The female teachers' performance

The matter concerns my mother, Yu Lili, who is forty years old and a university cadre working in the school's Women's Affairs Committee.

As usual, she became very busy during the winter break. This year, as the director, she seems even more dedicated, leaving early and returning late every day, as if rushing to do something. She appears quite tired when she gets home, but also seems happy, as if she's had a fun day.

This Saturday, Mom hurriedly finished breakfast at seven in the morning and rushed out. I said, "Mom, you have to work on Saturday?" She said, "Isn't it always like this? There's a lot to do at the end of the year, everyone has to work overtime. Besides, I just became a manager this year, so I have to work even harder, don't you think?" Saying that, she walked out the door with a smile. The doubt that had been surfacing in my heart every year rose up again, and even more so than before, "What kind of work do they actually do?" Watching Mom's receding figure from the window, I asked myself silently. No, I must find out this year! I decided to secretly follow her to see for myself tomorrow.

The next day, Mom was about to leave again just after seven o'clock. I said, "Mom, I'm going to a classmate's house to play today, I might be back late." She said, "Okay, don't stay out too late!" Saying that, she turned and left.

As soon as she closed the door, I quickly got dressed, put on my shoes, and went out. Seeing that Mom had already set off on her electric bicycle, I immediately took my mountain bike from the garage and chased after her. Luckily, she wasn't riding very fast, and soon I saw a woman in a blue coat in the distance—that was Mom.

I kept a distance from her, and half an hour later we arrived at the school. "Mom's here to work," I thought. School was quiet after the holidays; most students had gone home, and the campus felt deserted. She didn't ride to the administration building, which caught my attention. Didn't they work there?

I saw Mom ride her bike to a small building behind the teaching building. It was an abandoned little building. I remembered it used to be used for rehearsals by the school's arts department. After the multi-purpose activity building was built, it was no longer used. The little building looked rather dilapidated, and no one paid any attention to it.

"What's she doing there?" I wondered to myself. To avoid my mother finding my car, I deliberately parked it in a shady spot next to the library. I figured no one would go there.

Five minutes later, someone rode up on a bicycle. She was also a teacher from the women's committee, about the same age as them. She said to my mother, "Director Yu, you're here? I'm sorry I'm late." My mother smiled and said, "Not late at all, just in time. You've all been working so hard lately. Let's go inside!" My mother walked in front, followed by seven colleagues. My mother took out a key and unlocked a rusty lock on the door of the small building. The door opened, and they all followed me inside. I heard the door lock itself from the inside. My suspicions deepened. What were these female teachers doing in this abandoned building?

I emerged from the woods and circled the building. I noticed a broken lock on one window, so I opened it and carefully climbed inside. The floor was covered in a thick layer of dust; it seemed no one had been there for a long time.

There was no one on the first floor, but I heard some noises coming from the second floor. I quietly made my way up, feeling like a thief.

The sounds were coming from a room. I went over; the door was closed, but I could definitely hear a woman's voice coming from inside. I walked around the room, but the windows were all covered by thick curtains, so I couldn't see inside at all. What should I do? Then I saw a back door, so I gently pushed it. The door opened a crack, and thankfully, the back door only had a single pin tumbler lock on the handle, which was quite loose.

I listened carefully and could hear voices inside. Although it was very quiet all around, the sounds were still easy to hear. I heard my mother say, "Yesterday's rehearsal went quite well. You've been improving every day these past few days. Today, let's practice and refine it a bit more. Everyone, get ready!" I was puzzled. "What rehearsal? Why are you making such a fuss? Mom has never mentioned it before!" I saw them take off their shoes and coats and put them aside. "Are they going to dance? They're all in their forties and fifties, what are they going to dance for?" I thought to myself.

Then Mom took off her purple sweater, revealing a white thermal undershirt underneath. The other teachers also took off their sweaters, and I was startled again: "What are they going to do?" Then Mom's next move left me speechless: she unzipped her pants and deftly pulled them down. "What are they doing…" I didn't dare think any further. The

other teachers also took off their pants; all eight of them were wearing thermal undershirts and long johns. My mother paused for a moment and asked, "Is everyone still cold?" "No, Director Yu." "It's quite warm in here." At this moment, I could also see the seven teachers clearly: Li Yuan and Zhang Tianya from the same college as my mother, Zhang Sufang and Wang Lisha from the College of Literature, Zhao Juanjuan from the College of Foreign Languages, Guan Lingling from the Music Department of the College of Arts, and Pang Yan from the Fashion Design major.

Mom laughed and said, "Teacher Pang's idea is really good. This year, everyone should wear tight-fitting thermal underwear, so we don't have to order new ones and change them as we used to, which is uncomfortable." Everyone agreed, "Yes! That's a great idea, really good." Teacher Pang also smiled and said, "I also wanted it to be more natural, and of course, it's also good to be more convenient. Hehe!" When I heard this, I thought, "And in previous years, do they do this every winter vacation...?" I didn't have time to think further and continued watching.

All eight of them were indeed wearing tight-fitting underwear, which was a bit different from ordinary thermal underwear. It clung tightly to their bodies, highlighting their female figures. Especially Mom, in her snow-white underwear, her breasts were large and firm, and her buttocks were round and perky. She didn't look like a forty-year-old woman at all; she was so charming! The other teachers were also quite attractive, each wearing different colored bodysuits, looking much younger and exuding feminine charm.

My penis gradually hardened, and I touched my bulging crotch, swallowing hard. Mom turned on a tape recorder on the floor, and a burst of upbeat music from European and American bars immediately blasted out, mixed with many sexy and ambiguous elements. Mom

clapped her hands and said, "Let's begin!" Everyone lined up and began a series of movements: raising their arms, kicking their legs, turning around, and twisting their waists—a truly dynamic dance routine.

After jumping for five or six minutes, Mom clapped her hands three times and said, "One two, take off your tops!" Everyone immediately and skillfully took off their bras, swung them around their heads twice, and threw them behind them, instantly revealing eight pairs of breasts encased in eight bras. Mom's were the biggest and firmest, and the red bra she wore was incredibly alluring, with most of her breasts exposed. It was the first time I had ever seen Mom's breasts, along with the other seven teachers'—it was so stimulating!

Mom said, "Get moving!" Everyone immediately shook their upper bodies, and the eight pairs of breasts bounced up and down. Just as I was enjoying admiring the breasts, Mom suddenly shouted, "One two, sisters, take off your pants!" Everyone immediately took off their thermal underwear, their movements quite synchronized. They tossed them onto the ground, took a step forward, leaving eight pairs of pants behind them.

Each teacher was wearing a pair of briefs. Mom was wearing her usual beige underwear, the kind that usually hung out to dry on the balcony—utterly ordinary, but today it looked inexplicably sexy. The other teachers were also wearing ordinary underwear, except for Teacher Pang, who was more fashionable, wearing a very revealing pair of lace underwear.

I stared intently at their lower bodies. My mother shouted, "Twist it!" Everyone turned around and twisted their hips in unison. Eight big butts were right in front of me, and I felt like I couldn't breathe.

After twisting for a few minutes, I thought to myself, "Do we have to take them all off?" Before I could think any further, my mother spoke with her back to me, "One two, get your bras!" I saw all eight of them still twisting their hips while reaching behind their backs to unhook their bras!

They all took off their bras in unison. They each held their bras in their right hand and covered their nipples with their left arm and palm. They turned around, laughing, and twirled their bras three times in their hands. My mother in the middle threw her bra out first, and the other seven teachers immediately threw theirs out as well.

They were still writhing, and Mom said to the front, "Want to see?" Then she added, "Sisters, are you willing to keep showing?" Everyone shouted in unison, "Yes! As long as Director Yu says so!" Mom said, "One at a time!" She first removed her left hand from her breast, completely exposing it. One by one, the teachers on both sides revealed their breasts, and suddenly eight pairs of breasts were displayed in front of me. I couldn't hold back any longer, so I suddenly unzipped my pants, pulled out my penis, and started rubbing it. I couldn't take it anymore! It was the first time I had ever seen so many breasts swaying in front of me.

They were shaking their breasts up and down just like before, with eight pairs of nipples bouncing up and down. I noticed that my mother's nipples were light brown, and they were sexier than the other teachers'. The mother shouted the slogan, "One two places, one two places!" Everyone followed her slogan, shaking their breasts up and down in unison. Although Zhang Sufang from the School of Literature had slightly sagging breasts, she still laughed and bounced energetically, displaying her body to the fullest. They danced passionately for a few more minutes, and the most exciting moment was about to arrive. Sure enough, the mother said, "Sisters, are you still willing to show your vulva?" Everyone said in unison, "Yes!" The mother said, "Sisters, one two places, take off your underwear!" Everyone bent down and took off their underwear, twirling them over their heads a few times as before, and then throwing them forward with all their might.

I saw eight thick tufts of black pubic hair peeking out. Zhao Juanjuan from the Foreign Languages Department had the thickest and darkest pubic hair, looking incredibly sexy. I first looked at my mother, then at this teacher, then that one, and before I knew it, my face was flushed, and of course, my glans was red from the engorgement.

They then did something even more stimulating: they all turned around, knelt on the ground, supported themselves with their hands, and arched their buttocks up and down, as if inviting someone to penetrate them. After a while, my mother said, "Spread your legs!" Everyone immediately spread their legs, displaying all eight vaginas, still arching up and down, looking even more stimulating than before.

A moment later, they stood up again, legs spread, hips thrusting forward, touching their pubic hair. Then they bent over, letting their large breasts sway. The striptease performance reached its climax, and I felt myself about to climax, a tingling sensation spreading through my penis.

Suddenly, I felt a heat below, and my semen shot out, spraying directly onto the door. The striptease performance ended in this climax. I quickly and secretly ran to the bathroom, wiped my penis clean with a napkin, and splashed water on my burning face to calm myself down. I never dreamed my mother and those teachers would do such a thing.

After I finished, I secretly went to the back door and peeked through the crack. The teachers all looked tired, wiping the sweat from their heads and breasts with tissues.

My mother said, "The rehearsal went very well this time, everyone worked hard!" The teachers seemed still immersed in excitement, all smiling and saying, "It's all thanks to Director Yu's excellent direction!" My mother said, "Not at all, it's mainly thanks to everyone's support! This time, we must thank Teacher Zhang Tianya. She secretly downloaded a lot of striptease videos at home and burned them onto CDs for everyone to study. Several times, to avoid being discovered by her family, she stayed up until the middle of the night." "If it weren't for her, I really wouldn't know how to dance a striptease!" Teacher Zhang Tianya laughed, her face slightly red. Her mother walked over, patted her shoulder to express her gratitude, and then said, "There are still some things to pay attention to when dancing a striptease. Striptease is about teasing, and it's different from aerobics." Everyone nodded in agreement. The mother continued, "For example, when you wiggle your hips, the movements should be natural." As she spoke, she raised her hands and wiggled them a few times, then said, "Teacher Li, I feel that your movement is a bit stiff. Try it again." Teacher Li also raised her hands and wiggled her large but slightly sagging buttocks. The mother adjusted her hips and waist movements a few times with her hands, saying, "Like this is fine. Practice a few more times in the next few days." Teacher Li smiled and said, "Okay." The other teachers also practiced wiggling their hips a few times.

The mother then said, "When shaking your breasts, make sure they shake fully, in rhythm with the music, and concentrate your strength in your upper body." She demonstrated by shaking her own breasts, and then had each teacher shake their breasts in the same way for her. After watching, she was quite satisfied, nodded, and said, "Yes, everyone did very well, it felt great." "Mom continued, 'Now that we've talked about buttocks and breasts, we're going to talk about that part of us women, which is something we have to talk about. Leaders especially like to look at that area, and it's the most provocative part, so when we jump to the back, we must spread our legs wide and show it completely without any reservations.' Mom is a rather conservative person, and she never said the word 'vagina' in this setting, but I felt that it was particularly lewd for her to say these words, as if she were openly telling all the teachers to show their vulvas."

Mom continued, "Before the official performance, everyone must wear clean underwear, preferably in bright colors, the leaders like that. Also, bras and panties should be as small and close-fitting as possible, not too big, so it looks sexy. Also, wear briefs, don't wear boxer briefs, they're not convenient to take off." Mom paused, touched her own bottom, perhaps a little tired, and continued, "That day you can put on some perfume, just not too strong; you can also apply some powder, so the skin is smoother and easier to take off clothes. Also, make sure your lower body is clean, we're all getting old, it's not as tender there anymore..." As she spoke, she couldn't help but laugh, and the other teachers smiled knowingly as well.

It was almost Chinese New Year. One day, before rehearsal, my mother said, "The official performance is tomorrow. Everyone has practiced very well these past few days. We only need to practice twice today. Go back and prepare well." They practiced twice that day. My mother gave them some instructions, and then they moved several sofa chairs from an abandoned classroom next door and placed them at the back of the dance studio. I had been peeking through the crack in the door from the men's restroom. I was surprised to see that they had prepared all this. How thoughtful! After moving the chairs, they wiped the dust off and left.

The exciting day was almost here. I suppressed the excitement welling up inside me, and even the cold wind seemed less biting.

The next day, my mother left early as usual, and I set off as soon as she left. I rode a little faster today because I wanted to hide near the small building before the leaders arrived. I was especially eager to see which school leaders wanted to see their performance. When I arrived at school, I parked my bicycle in the shady spot next to the library, then secretly went to the grove of trees next to the small building, watching intently at the entrance. My mother and seven teachers had arrived. My mother smiled and said to everyone, "Are you all ready? Hehe, don't be nervous, it's not the first time." The teachers all said, "Director Yu, don't worry, we'll perform well." My mother gave a few more instructions, checked her watch, and said, "The leaders will be here soon. I think you should go up and prepare first, and I'll bring the leaders up in a bit." Everyone agreed.

Mom opened the door, and all seven teachers went inside. She locked the door again and waited by the path, glancing at her watch every now and then. About ten minutes later, I heard the sound of cars on the road. They were two ordinary vans, not the luxury cars the school leaders rode in. Could it be them?

Just then, the cars stopped in front of the building. Mom went to look, and seven or eight people got out of the two cars—all middle-aged men in their forties and fifties. The one in the lead greeted Mom warmly. Looking closer, I realized it was Principal Zhang from our school! He's definitely someone important!

I heard my mother say, "Hello, Principal Zhang! Why did you come in this car today?" Principal Zhang said, "Hehe, I was afraid of being recognized, so I specially rented two old vans. That way, it won't attract attention! Hahaha..." The other leaders also laughed along, and one of them said, "Principal Zhang is the most thoughtful. Hehe!" I looked and saw that it was Director Ding from the Academic Affairs Office.

While they were talking, I got a good look at each leader. There were seven people in total: Principal Zhang, Vice Principal Wang, Vice Principal Wu, Party Secretary Han, Director Yuan of the Graduate School, Director Ding of the Academic Affairs Office, and one I knew best, Chairman Jin of the University Labor Union. He was in charge of the Women's Committee, and I often saw him in the administration building.

The principal asked my mother, "Director Yu, is everything ready?" My mother replied, "Everything's ready, Principal Zhang. Don't worry, it'll be amazing!" My mother opened the door and led the seven school leaders inside. I heard the door lock behind her. I waited there for five minutes, guessing they were all inside, before sneaking in through the window and going up to the second floor. There was no one in the hallway; they must have all gone into their rooms.

I peeked through the crack in the back door and, sure enough, eight teachers and seven leaders had gone in. They were chatting, but I didn't listen carefully. They were talking about taking medication. The leaders were all quite old, so it wasn't surprising that they took medication for this kind of thing, especially given how intense it was today.

My mother and the female teacher had taken off their clothes and shoes; they seemed ready.

The leaders chatted for a while longer, then Principal Zhang rubbed his hands and said, "Everyone, look, can we begin?" He seemed a little impatient. Principal Zhang was only in his forties, and in recent years, he had become quite successful; his sex drive should be rather strong. The other leaders indicated that they could proceed, and they all seemed excited.

Mom came over and said, "As long as Principal Zhang says the word, we can begin!" Principal Zhang said, "Then let's begin!" The seven leaders sat on the sofa chairs, and the principal said, "Director Yu, let's begin!" Mom stood in front of the seven teachers, smiling, and said, "Next, please enjoy a group striptease performance brought to you by our Women's Committee teachers!" The leaders clapped a few times.

Mom pressed the switch on the tape recorder, and a few seconds later, passionate rock music burst out. I knew that music all too well; I'd been listening to it every day lately. To the music, they made all sorts of extremely provocative movements, just like in rehearsals. Finally, they were all naked, their underwear completely off, eight alluring nude bodies swaying, each one completely absorbed.

Even the leaders couldn't sit still anymore; soon, someone would take off a piece of clothing. After the striptease, everyone was completely naked. Principal Zhang led the applause again, and everyone expressed their satisfaction, their faces beaming.

My mother stepped forward again and said, "Now, please enjoy the passionate performance by our teachers!" I saw that Teacher Guan from the music department had changed a cassette tape and played a folk song. Wasn't that my mother's favorite, "Good Days"? No wonder she'd been listening to it so much these past few days.

My mother stood at the front and sang the entire song completely naked. The other seven teachers were also naked, standing hand in hand, swaying from side to side as backup dancers. Every now and then, they had to turn around so the leaders could get a good look from both the front and back. I noticed that almost every leader was intentionally or unintentionally putting their hands on their genitals—any normal person would react that way.

After my mother finished singing, she joined the dancers, and Teacher Li took her place. And so, each teacher sang a folk song they were good at, completely naked. They all sang very well, and the leaders listened with great interest.

After the eight teachers finished singing, Mom stepped forward again and said, "Next, it's time for the leaders and the teachers from the Women's Committee to interact. This can be any form of interaction between men and women." When she said this, her face was slightly red, whether from the heat or from feeling embarrassed, I didn't know: "Please, leaders, choose your interaction partners first." Everyone told the principal to choose first, and the principal smiled and said, "Then I'll choose Director Yu! Hehe!" The next six leaders also each chose a teacher. In the end, Teacher Wang Lisha was not chosen, and everyone humbly said, "Let's give it to the principal!" The principal couldn't refuse, so she agreed.

The passionate sexual interaction began, and I watched Mom, Teacher Wang, and Principal Zhang's couple. The mother laughed and said,

"Principal Zhang, it's so hot in here, I think you should take your pants off!" Principal Zhang said, "Okay! Okay!" Saying that, he took off his long pants and thermal underwear and put them aside. He was wearing a pair of boxer shorts underneath, nothing special, his penis bulging out of the shorts, with a little water stain on them. The mother said, "Principal Zhang, how about you stand up, and I'll give you... Teacher Wang will give you a push from behind?" The mother was still a bit conservative and didn't say "that."

Principal Zhang said, "Okay!" He stood up, and Teacher Wang walked behind him, put her hands on the principal's shoulders, her breasts pressing against his back and pushing him up, making Principal Zhang's penis even more erect.

The mother squatted down, looking at the principal. Principal Zhang smiled and nodded. The mother slowly took off his underwear. Principal Zhang's penis was quite large and hard, indicating that he was in good physical condition. The mother grasped his penis and gently rubbed it. Principal Zhang looked very pleased, praising repeatedly, "Hmm, Director Yu's hands are really capable. No wonder Chairman Jin always praises you. Very good! Teacher Wang's massage is also good. You are both very comfortable." The mother and Teacher Wang smiled and continued to serve the principal.

The other teachers also began their work, rubbing the leader's penis, while the leader touched the teachers' bodies. Secretary Han was the oldest, over fifty years old, and perhaps his erection wasn't very good in that area; Teacher Li Yuan had been rubbing him for a while, but he was still only half-erect. To help him get an erection, Teacher Li had started using her breasts and her tongue to lick him.

Mom whispered, "Principal Zhang, would you like me to give you a blowjob?" The principal said, "Sure! Thank you, Director Yu." "Still being polite at a time like this; leaders really do things differently from ordinary people!" I thought to myself.

Mom stuck out her tongue and gently licked the principal's glans, while simultaneously making lewd moans that sounded incredibly alluring. Principal Zhang couldn't take it anymore and couldn't help but let out "Ah...ah..." sounds.

After a while of intense oral sex, the principal suddenly said, "Director Yu, I...I want..." As he spoke, Mom's mouth stopped moving, but his penis was still inside. Principal Zhang let out two soft "ah ah" sounds. Mom waited a moment, then slowly sucked a few more times.

"Could it be..." I wondered.

Then Mom spat out his penis, which was covered in milky white semen. Principal Zhang had ejaculated directly into Mom's mouth!

Principal Zhang said, "Director Yu, I'm sorry, I didn't have time to..." Mom shut her mouth and remained silent, making a few swallowing motions; it seemed she had swallowed the semen!

Then Mom said, "It's okay, Principal Zhang, it's only right that you ejaculate in my mouth, it feels better that way. Let me lick it clean for you!" She then used her tongue to lick the remaining semen off the principal's glans.

At that moment, I heard another loud shout from a man. I looked and saw that Director Jin had also ejaculated, shooting his semen onto Teacher Pang's face. The atmosphere in the room grew increasingly intense, and everyone let loose and played around.

After a moment, the principal said, "Director Yu, your oral skills are really good! Very good!" Mom smiled but didn't say anything.

Principal Zhang squatted down, touched Mom's buttocks, and said, "Director Yu, your buttocks are nice! Come on, stand up." Mom obediently stood up, and the principal gestured for her to turn around.

The principal suddenly remembered Teacher Wang, turned around and smiled, saying, "Teacher Wang, your breasts feel really good, thank you! Now you can go and serve the other leaders, let them have some fun too!" Teacher Wang smiled and said, "Thank you, Principal! Okay!" She went to ask the other leaders if they needed two people to serve them, and Director Ding from the Academic Affairs Office agreed. She then used her big breasts to massage Director Ding's penis.

The principal turned around, kneading his mother's buttocks with both hands, praising them with a series of "tsk tsk" sounds: "Hmm, really good, big and round, so much better than my withered buttocks!" His mother responded, "Hmm, it's a rare treat, Principal, don't be shy! Go ahead and do it!" The principal actually buried his head in his mother's big buttocks, licking them wildly, and even biting them a few times. It seems he really liked his mother's big buttocks. No wonder, my penis gets hard whenever I see my mother's buttocks.

The principal played with her for a while, then gradually moved towards the mother's vulva. He pinched her buttocks while simultaneously reaching around to touch her pubic hair. The mother, in turn, squeezed her large breasts, moaning loudly and seemingly enjoying herself immensely—whether genuinely pleasured or deliberately making noises to please the principal was unclear.

Having had his fill of her buttocks, the principal gestured for the mother to turn to face him, indicating he was about to play with her vulva. The mother spread her legs wide, thrusting her vulva forward, like a stripper—a very alluring sight!

Principal Zhang buried his head between his mother's legs and began licking her vulva wildly with his tongue. His mother's moans grew louder: "Principal Zhang...you...it feels so good...ah...um...um...I can't take it anymore...it's so itchy...so good...ah...ah..." Principal Zhang also felt great, praising repeatedly: "Director Yu, your vulva is so beautiful, so delicious, much more fun than my wife's!" I saw a lot of vaginal fluid flowing from my mother's vulva, which Principal Zhang greedily sucked, as if it were holy water. Soon, his lips were covered in white, sticky fluid.

After licking for a while, I saw Principal Zhang reach for his penis, which was clearly erect. He suddenly stood up and said, "Come on, Director Yu, rub me." He then pulled his mother's hand and placed it on his penis.

His mother asked, "With your mouth or your hand?" Principal Zhang said, "No, with there." He pointed to his mother's large breasts.

At this moment, Mom's breasts became even firmer with excitement. Principal Zhang pinched and played with them a few times, then took the erect nipples into his mouth and licked them for a while. His hands also kept stroking Mom's buttocks and vulva, and his fingers kept probing inside her vulva. Mom seemed to be unable to bear it any longer, and gently grabbed the principal's hand, saying, "Principal Zhang, there... there, be gentler, um..." After a while, Principal Zhang also couldn't bear it anymore, stopped sucking, and gestured for Mom to squat down. Mom understood and sandwiched Principal Zhang's penis between her breasts, pressing hard and rubbing it up and down. Principal Zhang watched Mom's actions intently, his eyes shining with infinite satisfaction.

After pushing her breasts for ten minutes, Principal Zhang said, "Director Yu, you did a great job! Let's start doing *that*!

You're on the bottom." Mom immediately lay down on the ground, legs spread wide, her large vulva facing Principal Zhang. Principal Zhang squatted down and thrust into Mom's vulva with a sudden, powerful thrust, penetrating her completely. He wasn't wearing a condom!

Mom cried out, and Principal Zhang seemed even more excited, starting to thrust slowly and gradually increasing the speed, just like in pornographic films—nothing special. He was very absorbed in it, not saying a word, seemingly enjoying Mom's large vulva.

After more than ten minutes of penetration, Principal Zhang still hadn't ejaculated, so his physique seemed pretty good. He pulled out his penis and said, "Director Yu, try from behind." My mother struggled to get up, placing her hands on the sofa and raising her buttocks high.

Principal Zhang didn't say much, spreading my mother's buttocks and launching into a frenzied series of thrusts. My mother's body swayed back and forth with each impact, emitting loud moans. At this moment, I noticed the moans and groans of men and women echoing throughout the room, quite a lively scene. Every leader was having sex with the female teacher beneath them. I simply couldn't believe it was real; it was no different from the group sex scenes I'd seen in pornographic films.

When I looked at Principal Zhang again, he was holding my mother's waist. After a series of extremely violent thrusts, he stopped moving, panting heavily, apparently having ejaculated. Sure enough, he pulled out his penis, which was covered in milky white semen and vaginal fluid. Semen was also flowing from my mother's vagina, indicating that her vagina was completely filled with semen. My mother sat weakly on the ground, licking Principal Zhang's penis clean. Principal Zhang seemed very satisfied and whispered a few words in my mother's ear, but they were too soft for me to hear. After each teacher and leader had finished, there was an exchange. My mother had slept with Vice Principal Wu, Minister Yuan, and Director Ding from the Academic Affairs Office. The process was similar for each of them, so I won't go into details here. Minister Yuan, who enjoyed anal sex, ejaculated inside my mother's anus. They engaged in debauchery for several hours, until everyone was exhausted. Clothes, pants, and toilet paper were scattered everywhere; everyone had released their sexual desires to the fullest. When they left, Principal Zhang and the other leaders praised the Women's Committee's work, especially commending my mother for her excellent arrangements and how comfortable it was. Finally, the principal gave each teacher a red envelope.

It was almost dark, and everyone chatted for a while before leaving, seemingly still wanting more. I secretly ran up to the third floor and watched them all leave before climbing out. I couldn't believe that all of this had happened right before my eyes.

From that moment on, my attitude towards my mother, her colleagues, and the school leaders underwent a complete change. It turns out that human desire can drive people to do anything unbelievable.

The matter concerns my mother, Yu Lili, who is forty years old and a university cadre working in the school's Women's Affairs Committee.

As usual, my mother became very busy during the winter break. This year, as the director, she seemed even more enthusiastic about her work, leaving early and returning late every day, as if rushing to do something. She seemed quite tired when she came home, but also appeared happy, as if she had done something interesting that day.

This Saturday, Mom hurriedly finished breakfast at seven in the morning and rushed out. I said, "Mom, you have to work on Saturday?" She said, "Isn't it always like this? There's a lot to do at the end of the year, everyone has to work overtime. Besides, I just became a manager this year, so I have to work even harder, don't you think?" Saying that, she walked out the door with a smile. The doubt that had been surfacing in my heart every year rose up again, and even more so than before, "What kind of work do they actually do?" Watching Mom's receding figure from the window, I asked myself silently. No, I must find out this year! I decided to secretly follow her to see for myself tomorrow.

The next day, Mom was about to leave again just after seven o'clock. I said, "Mom, I'm going to a classmate's house to play today, I might be back late." She said, "Okay, don't stay out too late!" Saying that, she turned and left.

As soon as she closed the door, I quickly got dressed, put on my shoes, and went out. Seeing that Mom had already set off on her electric bicycle, I immediately took my mountain bike from the garage and chased after her. Luckily, she wasn't riding very fast, and soon I saw a woman in a blue coat in the distance—that was Mom.

I kept a distance from her, and half an hour later we arrived at the school. "Mom's here to work," I thought. School was quiet after the holidays; most students had gone home, and the campus felt deserted. She didn't ride to the administration building, which caught my attention. Didn't they work there?

I saw Mom ride her bike to a small building behind the teaching building. It was an abandoned little building. I remembered it used to be used for rehearsals by the school's arts department. After the multi-purpose activity building was built, it was no longer used. The little building looked rather dilapidated, and no one paid any attention to it.

"What's she doing there?" I wondered to myself. To avoid my mother finding my car, I deliberately parked it in a shady spot next to the library. I figured no one would go there.

Five minutes later, someone rode up on a bicycle. She was also a teacher from the women's committee, about the same age as them. She said to my mother, "Director Yu, you're here? I'm sorry I'm late." My mother smiled and said, "Not late at all, just in time. You've all been working so hard lately. Let's go inside!" My mother walked in front, followed by seven colleagues. My mother took out a key and unlocked a rusty lock on the door of the small building. The door opened, and they all followed me inside. I heard the door lock itself from the inside. My suspicions deepened. What were these female teachers doing in this abandoned building?

I emerged from the woods and circled the building. I noticed a broken lock on one window, so I opened it and carefully climbed inside. The floor was covered in a thick layer of dust; it seemed no one had been there for a long time.

There was no one on the first floor, but I heard some noises coming from the second floor. I quietly made my way up, feeling like a thief.

The sounds were coming from a room. I went over; the door was closed, but I could definitely hear a woman's voice coming from inside. I walked around the room, but the windows were all covered by thick curtains, so I couldn't see inside at all. What should I do? Then I saw a back door, so I gently pushed it. The door opened a crack, and thankfully, the back door only had a single pin tumbler lock on the handle, which was quite loose.

I listened carefully and could hear voices inside. Although it was very quiet all around, the sounds were still easy to hear. I heard my mother say, "Yesterday's rehearsal went quite well. You've been improving every day these past few days. Today, let's practice and refine it a bit more. Everyone, get ready!" I was puzzled. "What rehearsal? Why are you making such a fuss? Mom has never mentioned it before!" I saw them take off their shoes and coats and put them aside. "Are they going to dance? They're all in their forties and fifties, what are they going to dance for?" I thought to myself.

Then Mom took off her purple sweater, revealing a white thermal undershirt underneath. The other teachers also took off their sweaters, and I was startled again: "What are they going to do?" Then Mom's next move left me speechless: she unzipped her pants and deftly pulled them down. "What are they doing…" I didn't dare think any further. The

other teachers also took off their pants; all eight of them were wearing thermal undershirts and long johns. My mother paused for a moment and asked, "Is everyone still cold?" "No, Director Yu." "It's quite warm in here." At this moment, I could also see the seven teachers clearly: Li Yuan and Zhang Tianya from the same college as my mother, Zhang Sufang and Wang Lisha from the College of Literature, Zhao Juanjuan from the College of Foreign Languages, Guan Lingling from the Music Department of the College of Arts, and Pang Yan from the Fashion Design major.

Mom laughed and said, "Teacher Pang's idea is really good. This year, everyone should wear tight-fitting thermal underwear, so we don't have to order new ones and change them as we used to, which is uncomfortable." Everyone agreed, "Yes! That's a great idea, really good." Teacher Pang also smiled and said, "I also wanted it to be more natural, and of course, it's also good to be more convenient. Hehe!" When I heard this, I thought, "And in previous years, do they do this every winter vacation...?" I didn't have time to think further and continued watching.

All eight of them were indeed wearing tight-fitting underwear, which was a bit different from ordinary thermal underwear. It clung tightly to their bodies, highlighting their female figures. Especially Mom, in her snow-white underwear, her breasts were large and firm, and her buttocks were round and perky. She didn't look like a forty-year-old woman at all; she was so charming! The other teachers were also quite attractive, each wearing different colored bodysuits, looking much younger and exuding feminine charm.

My penis gradually hardened, and I touched my bulging crotch, swallowing hard. Mom turned on a tape recorder on the floor, and a burst of upbeat music from European and American bars immediately blasted out, mixed with many sexy and ambiguous elements. Mom

clapped her hands and said, "Let's begin!" Everyone lined up and began a series of movements: raising their arms, kicking their legs, turning around, and twisting their waists—a truly dynamic dance routine.

After jumping for five or six minutes, Mom clapped her hands three times and said, "One two, take off your tops!" Everyone immediately and skillfully took off their bras, swung them around their heads twice, and threw them behind them, instantly revealing eight pairs of breasts encased in eight bras. Mom's were the biggest and firmest, and the red bra she wore was incredibly alluring, with most of her breasts exposed. It was the first time I had ever seen Mom's breasts, along with the other seven teachers'—it was so stimulating!

Mom said, "Get moving!" Everyone immediately shook their upper bodies, and the eight pairs of breasts bounced up and down. Just as I was enjoying admiring the breasts, Mom suddenly shouted, "One two, sisters, take off your pants!" Everyone immediately took off their thermal underwear, their movements quite synchronized. They tossed them onto the ground, took a step forward, leaving eight pairs of pants behind them.

Each teacher was wearing a pair of briefs. Mom was wearing her usual beige underwear, the kind that usually hung out to dry on the balcony—utterly ordinary, but today it looked inexplicably sexy. The other teachers were also wearing ordinary underwear, except for Teacher Pang, who was more fashionable, wearing a very revealing pair of lace underwear.

I stared intently at their lower bodies. My mother shouted, "Twist it!" Everyone turned around and twisted their hips in unison. Eight big butts were right in front of me, and I felt like I couldn't breathe.

After twisting for a few minutes, I thought to myself, "Do we have to take them all off?" Before I could think any further, my mother spoke with her back to me, "One two, get your bras!" I saw all eight of them still twisting their hips while reaching behind their backs to unhook their bras!

They all took off their bras in unison. They each held their bras in their right hand and covered their nipples with their left arm and palm. They turned around, laughing, and twirled their bras three times in their hands. My mother in the middle threw her bra out first, and the other seven teachers immediately threw theirs out as well.

They were still writhing, and Mom said to the front, "Want to see?" Then she added, "Sisters, are you willing to keep showing?" Everyone shouted in unison, "Yes! As long as Director Yu says so!" Mom said, "One at a time!" She first removed her left hand from her breast, completely exposing it. One by one, the teachers on both sides revealed their breasts, and suddenly eight pairs of breasts were displayed in front of me. I couldn't hold back any longer, so I suddenly unzipped my pants, pulled out my penis, and started rubbing it. I couldn't take it anymore! It was the first time I had ever seen so many breasts swaying in front of me.

They were shaking their breasts up and down just like before, with eight pairs of nipples bouncing up and down. I noticed that my mother's nipples were light brown, and they were sexier than the other teachers'. The mother shouted the slogan, "One two places, one two places!" Everyone followed her slogan, shaking their breasts up and down in unison. Although Zhang Sufang from the School of Literature had slightly sagging breasts, she still laughed and bounced energetically, displaying her body to the fullest. They danced passionately for a few more minutes, and the most exciting moment was about to arrive. Sure enough, the mother said, "Sisters, are you still willing to show your cunts?" Everyone said in unison, "Yes!" The mother said, "Sisters, one two places, take off your underwear!" Everyone bent down and took off their underwear, twirling them over their heads a few times as before, and then throwing them forward with all their might.

I saw eight thick tufts of black pubic hair peeking out. Zhao Juanjuan from the Foreign Languages Department had the thickest and darkest pubic hair, looking incredibly sexy. I first looked at my mother, then at this teacher, then that one, and before I knew it, my face was flushed, and of course, my glans was red from the engorgement.

They then did something even more stimulating: they all turned around, knelt on the ground, supported themselves with their hands, and arched their buttocks up and down, as if inviting someone to penetrate them. After a while, my mother said, "Spread your legs!" Everyone immediately spread their legs, displaying all eight vaginas, still arching up and down, looking even more stimulating than before.

A moment later, they stood up again, legs spread, hips thrusting forward, touching their pubic hair. Then they bent over, letting their large breasts sway. The striptease performance reached its climax, and I felt myself about to climax, a tingling sensation spreading through my penis.

Suddenly, I felt a heat below, and my semen shot out, spraying directly onto the door. The striptease performance ended in this climax. I quickly and secretly ran to the bathroom, wiped my penis clean with a napkin, and splashed water on my burning face to calm myself down. I never dreamed my mother and those teachers would do such a thing.

After I finished, I secretly went to the back door and peeked through the crack. The teachers all looked tired, wiping the sweat from their heads and breasts with tissues.

My mother said, "The rehearsal went very well this time, everyone worked hard!" The teachers seemed still immersed in excitement, all smiling and saying, "It's all thanks to Director Yu's excellent direction!" My mother said, "Not at all, it's mainly thanks to everyone's support! This time, we must thank Teacher Zhang Tianya. She secretly downloaded a lot of striptease videos at home and burned them onto CDs for everyone to study. Several times, to avoid being discovered by her family, she stayed up until the middle of the night." "If it weren't for her, I really wouldn't know how to dance a striptease!" Teacher Zhang Tianya laughed, her face slightly red. Her mother walked over, patted her shoulder to express her gratitude, and then said, "There are still some things to pay attention to when dancing a striptease. Striptease is about teasing, and it's different from aerobics." Everyone nodded in agreement. The mother continued, "For example, when you wiggle your hips, the movements should be natural." As she spoke, she raised her hands and wiggled them a few times, then said, "Teacher Li, I feel that your movement is a bit stiff. Try it again." Teacher Li also raised her hands and wiggled her large but slightly sagging buttocks. The mother adjusted her hips and waist movements a few times with her hands and said, "Like this is fine. Practice it again in the next few days." Teacher Li smiled and said, "Okay." The other teachers also practiced twisting their hips a few times.

The mother continued, "When you shake your breasts, make sure they shake fully, in rhythm with the music, and concentrate your strength in your upper body." She demonstrated by shaking her breasts once, and then had each teacher do the same for her. After watching, she was quite satisfied, nodded, and said, "Yes, everyone did a great job, it felt really good." "Mom continued, 'Now that we've talked about buttocks and breasts, we're going to talk about that part of us women, which is something we have to talk about. Leaders especially like to look at that area, and it's the most provocative part, so when we jump to the back, we must spread our legs wide and show it completely without any reservations.' Mom is a rather conservative person, and she never said the word 'vagina' in this setting, but I felt that it was particularly lewd for her to say these words, as if she were openly telling all the teachers to show their vulvas."

Mom continued, "Before the official performance, everyone must wear clean underwear, preferably in bright colors, as the leaders like that. Also, bras and panties should be as small and close-fitting as possible, not too big, to look sexy. Also, wear briefs, not boxer briefs, as they're not convenient to take off." Mom paused, touched her own bottom, perhaps a little tired, and continued, "That day, you can put on some perfume, just not too strong; you can also apply some powder, so the skin is smoother and easier to take off clothes. Also, make sure your lower body is clean, we're all getting old, it's not as tender there anymore..." As she spoke, she couldn't help but laugh, and the other teachers smiled knowingly as well.

It was almost Chinese New Year. One day, before rehearsal, my mother said, "The official performance is tomorrow. Everyone has practiced very well these past few days. We only need to practice twice today. Go back and prepare well." They practiced twice that day. My mother gave them some instructions, and then they moved several sofa chairs from an abandoned classroom next door and placed them at the back of the dance studio. I had been peeking through the crack in the door from the men's restroom. I was surprised to see that they had prepared all this. How thoughtful! After moving the chairs, they wiped the dust off and left.

The exciting day was almost here. I suppressed the excitement welling up inside me, and even the cold wind seemed less biting.

The next day, my mother left early as usual, and I set off as soon as she left. I rode a little faster today because I wanted to hide near the small building before the leaders arrived. I was especially eager to see which school leaders wanted to see their performance. When I arrived at school, I parked my bicycle in the shady spot next to the library, then secretly went to the grove of trees next to the small building and watched intently at the entrance. My mother and seven teachers had arrived. My mother smiled and said to everyone, "Are you all ready? Hehe, don't be nervous, it's not the first time." The teachers all said, "Director Yu, don't worry, we'll perform well." My mother gave a few more instructions, checked her watch, and said, "The leaders will be here soon. I think you should go up and get ready first, and I'll bring the leaders up in a bit." Everyone agreed.

Mom opened the door, and all seven teachers went inside. She locked the door again and waited by the path, glancing at her watch every now and then. About ten minutes later, I heard the sound of cars on the road. They were two ordinary vans, not the luxury cars the school leaders rode in. Could it be them?

Just then, the cars stopped in front of the building. Mom went to look, and seven or eight people got out of the two cars—all middle-aged men in their forties and fifties. The one in the lead greeted Mom warmly. Looking closer, I realized it was Principal Zhang from our school! He's definitely someone important!

I heard my mother say, "Hello, Principal Zhang! Why did you come in this car today?" Principal Zhang said, "Hehe, I was afraid of being recognized, so I specially rented two old vans. That way, it won't attract attention! Hahaha..." The other leaders also laughed along, and one of them said, "Principal Zhang is the most thoughtful. Hehe!" I looked and saw that it was Director Ding from the Academic Affairs Office.

While they were talking, I got a good look at each leader. There were seven people in total: Principal Zhang, Vice Principal Wang, Vice Principal Wu, Party Secretary Han, Director Yuan of the Graduate School, Director Ding of the Academic Affairs Office, and one I knew best, Chairman Jin of the University Labor Union. He was in charge of the Women's Committee, and I often saw him in the administration building.

The principal asked my mother, "Director Yu, is everything ready?" My mother replied, "Everything's ready, Principal Zhang. Don't worry, it'll be amazing!" My mother opened the door and led the seven school leaders inside. I heard the door lock behind her. I waited there for five minutes, guessing they were all inside, before sneaking in through the window and going up to the second floor. There was no one in the hallway; they must have all gone into their rooms.

I peeked through the crack in the back door and, sure enough, eight teachers and seven leaders had gone in. They were chatting, but I didn't listen carefully. They were talking about taking medication. The leaders were all quite old, so it wasn't surprising that they took medication for this kind of thing, especially given how intense it was today.

My mother and the female teacher had taken off their clothes and shoes; they seemed ready.

The leaders chatted for a while longer, then Principal Zhang rubbed his hands and said, "Everyone, look, can we begin?" He seemed a little impatient. Principal Zhang was only in his forties, and in recent years, he had become quite successful; his sex drive should be rather strong. The other leaders indicated that they could proceed, and they all seemed excited.

Mom came over and said, "As long as Principal Zhang says the word, we can begin!" Principal Zhang said, "Then let's begin!" The seven leaders sat on the sofa chairs, and the principal said, "Director Yu, let's begin!" Mom stood in front of the seven teachers, smiling, and said, "Next, please enjoy a group striptease performance brought to you by our Women's Committee teachers!" The leaders clapped a few times.

Mom pressed the switch on the tape recorder, and a few seconds later, passionate rock music burst out. I knew that music all too well; I'd been listening to it every day lately. To the music, they made all sorts of extremely provocative movements, just like in rehearsals. Finally, they were all naked, their underwear completely off, eight alluring nude bodies swaying, each one completely absorbed.

Even the leaders couldn't sit still anymore; soon, someone would take off a piece of clothing. After the striptease, everyone was completely naked. Principal Zhang led the applause again, and everyone expressed their satisfaction, their faces beaming.

My mother stepped forward again and said, "Now, please enjoy the passionate performance by our teachers!" I saw that Teacher Guan from the music department had changed a cassette tape and played a folk song. Wasn't that my mother's favorite, "Good Days"? No wonder she'd been listening to it so much these past few days.

My mother stood at the front and sang the entire song completely naked. The other seven teachers were also naked, standing hand in hand, swaying from side to side as backup dancers. Every now and then, they had to turn around so the leaders could get a good look from both the front and back. I noticed that almost every leader was intentionally or unintentionally putting their hands on their genitals—any normal person would react that way.

After my mother finished singing, she joined the dancers, and Teacher Li took her place. And so, each teacher sang a folk song they were good at, completely naked. They all sang very well, and the leaders listened with great interest.

After the eight teachers finished singing, Mom stepped forward again and said, "Next, it's time for the leaders and the teachers from the Women's Committee to interact. This can be any form of interaction between men and women." When she said this, her face was slightly red, whether from the heat or from feeling embarrassed, I didn't know: "Please, leaders, choose your interaction partners first." Everyone told the principal to choose first, and the principal smiled and said, "Then I'll choose Director Yu! Hehe!" The next six leaders also each chose a teacher. In the end, Teacher Wang Lisha was not chosen, and everyone humbly said, "Let's give it to the principal!" The principal couldn't refuse, so she agreed.

The passionate sexual interaction began, and I watched Mom, Teacher Wang, and Principal Zhang's couple. The mother laughed and said,

"Principal Zhang, it's so hot in here, I think you should take your pants off!" Principal Zhang said, "Okay! Okay!" Saying that, he took off his long pants and thermal underwear and put them aside. He was wearing a pair of boxer shorts underneath, nothing special, his penis bulging out of the shorts, with a little water stain on them. The mother said, "Principal Zhang, how about you stand up, and I'll give you... Teacher Wang will give you a push from behind?" The mother was still a bit conservative and didn't say "that."

Principal Zhang said, "Okay!" He stood up, and Teacher Wang walked behind him, put her hands on the principal's shoulders, her breasts pressing against his back and pushing him up, making Principal Zhang's penis even more erect.

The mother squatted down, looking at the principal. Principal Zhang smiled and nodded. The mother slowly took off his underwear. Principal Zhang's penis was quite large and hard, indicating that he was in good physical condition. The mother grasped his penis and gently rubbed it. Principal Zhang looked very pleased, praising repeatedly, "Hmm, Director Yu's hands are really capable. No wonder Chairman Jin always praises you. Very good! Teacher Wang's massage is also good. You are both very comfortable." The mother and Teacher Wang smiled and continued to serve the principal.

The other teachers also began their work, rubbing the leader's penis, while the leader touched the teachers' bodies. Secretary Han was the oldest, over fifty years old, and perhaps his erection wasn't very good in that area; Teacher Li Yuan had been rubbing him for a while, but he was still only half-erect. To help him get an erection, Teacher Li had started using her breasts and her tongue to lick him.

Mom whispered, "Principal Zhang, would you like me to give you a blowjob?" The principal said, "Sure! Thank you, Director Yu." "Still being polite at a time like this; leaders really do things differently from ordinary people!" I thought to myself.

Mom stuck out her tongue and gently licked the principal's glans, while simultaneously making lewd moans that sounded incredibly alluring. Principal Zhang couldn't take it anymore and couldn't help but let out "Ah...ah..." sounds.

After a while of intense oral sex, the principal suddenly said, "Director Yu, I...I want..." As he spoke, Mom's mouth stopped moving, but his penis was still inside. Principal Zhang let out two soft "ah ah" sounds. Mom waited a moment, then slowly sucked a few more times.

"Could it be..." I wondered.

Then Mom spat out his penis, which was covered in milky white semen. Principal Zhang had ejaculated directly into Mom's mouth!

Principal Zhang said, "Director Yu, I'm sorry, I didn't have time to..." Mom shut her mouth and remained silent, making a few swallowing motions; it seemed she had swallowed the semen!

Then Mom said, "It's okay, Principal Zhang, it's only right that you ejaculate in my mouth, it feels better that way. Let me lick it clean for you!" She then used her tongue to lick the remaining semen off the principal's glans.

At that moment, I heard another loud shout from a man. I looked and saw that Director Jin had also ejaculated, shooting his semen onto Teacher Pang's face. The atmosphere in the room grew increasingly intense, and everyone let loose and played around.

After a moment, the principal said, "Director Yu, your oral skills are really good! Very good!" Mom smiled but didn't say anything.

Principal Zhang squatted down, touched Mom's buttocks, and said, "Director Yu, your buttocks are nice! Come on, stand up." Mom obediently stood up, and the principal gestured for her to turn around.

The principal suddenly remembered Teacher Wang, turned around and smiled, saying, "Teacher Wang, your breasts feel really good, thank you! Now you can go and serve the other leaders, let them have some fun too!" Teacher Wang smiled and said, "Thank you, Principal! Okay!" She went to ask the other leaders if they needed two people to serve them, and Director Ding from the Academic Affairs Office agreed. She then used her big breasts to massage Director Ding's penis.

The principal turned around, kneading his mother's buttocks with both hands, praising them with a series of "tsk tsk" sounds: "Hmm, really good, big and round, so much better than my withered buttocks!" His mother responded, "Hmm, it's a rare treat, Principal, don't be shy! Go ahead and do it!" The principal actually buried his head in his mother's big buttocks, licking them wildly, and even biting them a few times. It seems he really liked his mother's big buttocks. No wonder, my penis gets hard whenever I see my mother's buttocks.

The principal played with her for a while, then gradually moved towards the mother's vulva. He pinched her buttocks while simultaneously reaching around to touch her pubic hair. The mother, in turn, squeezed her large breasts, moaning loudly and seemingly enjoying herself immensely—whether genuinely pleasured or deliberately making noises to please the principal was unclear.

Having had his fill of her buttocks, the principal gestured for the mother to turn to face him, indicating he was about to play with her vulva. The mother spread her legs wide, thrusting her vulva forward, like a stripper—a very alluring sight!

Principal Zhang buried his head between his mother's legs and began licking her vulva wildly with his tongue. His mother's moans grew louder: "Principal Zhang...you...it feels so good...ah...um...um...I can't take it anymore...it's so itchy...so good...ah...ah..." Principal Zhang also felt great, praising repeatedly: "Director Yu, your vulva is so beautiful, so delicious, much more fun than my wife's!" I saw a lot of vaginal fluid flowing from my mother's vulva, which Principal Zhang greedily sucked, as if it were holy water. Soon, his lips were covered in white, sticky fluid.

After licking for a while, I saw Principal Zhang reach for his penis, which was clearly erect. He suddenly stood up and said, "Come on, Director Yu, rub me." He then pulled his mother's hand and placed it on his penis.

His mother asked, "With your mouth or your hand?" Principal Zhang said, "No, with there." He pointed to his mother's large breasts.

At this moment, Mom's breasts became even firmer with excitement. Principal Zhang pinched and played with them a few times, then took the erect nipples into his mouth and licked them for a while. His hands also kept stroking Mom's buttocks and vulva, and his fingers kept probing inside her vulva. Mom seemed to be unable to bear it any longer, and gently grabbed the principal's hand, saying, "Principal Zhang, there... there, be gentler, um..." After a while, Principal Zhang also couldn't bear it anymore, stopped sucking, and gestured for Mom to squat down. Mom understood and sandwiched Principal Zhang's penis between her breasts, pressing hard and rubbing it up and down. Principal Zhang watched Mom's actions intently, his eyes shining with infinite satisfaction.

After pushing her breasts for ten minutes, Principal Zhang said, "Director Yu, you did a great job! Let's start doing *that*!

You're on the bottom." Mom immediately lay down on the ground, legs spread wide, her large vulva facing Principal Zhang. Principal Zhang squatted down and thrust into Mom's vulva with a sudden, powerful thrust, penetrating her completely. He wasn't wearing a condom!

Mom cried out, and Principal Zhang seemed even more excited, starting to thrust slowly and gradually increasing the speed, just like in pornographic films—nothing special. He was very absorbed in it, not saying a word, seemingly enjoying Mom's large vulva.

After more than ten minutes of penetration, Principal Zhang still hadn't ejaculated, so his physique seemed pretty good. He pulled out his penis and said, "Director Yu, try from behind." My mother struggled to get up, placing her hands on the sofa and raising her buttocks high.

Principal Zhang didn't say much, spreading my mother's buttocks and launching into a frenzied series of thrusts. My mother's body swayed back and forth with each impact, emitting loud moans. At this moment, I noticed the moans and groans of men and women echoing throughout the room, quite a lively scene. Every leader was having sex with the female teacher beneath them. I simply couldn't believe it was real; it was no different from the group sex scenes I'd seen in pornographic films.

When I looked at Principal Zhang again, he was holding my mother's waist. After a series of extremely violent thrusts, he stopped moving, panting heavily, apparently having ejaculated. Sure enough, he pulled out his penis, which was covered in milky white semen and vaginal fluid. Semen was also flowing from my mother's vagina, indicating that her vagina was completely filled with semen. My mother sat weakly on the ground, licking Principal Zhang's penis clean. Principal Zhang seemed very satisfied and whispered a few words in my mother's ear, but they were too soft for me to hear. After each teacher and leader had finished, there was an exchange. My mother had slept with Vice Principal Wu, Minister Yuan, and Director Ding from the Academic Affairs Office. The process was similar for each of them, so I won't go into details here. Minister Yuan, who enjoyed anal sex, ejaculated inside my mother's anus. They engaged in debauchery for several hours, until everyone was exhausted. Clothes, pants, and toilet paper were scattered everywhere; everyone had released their sexual desires to the fullest. When they left, Principal Zhang and the other leaders praised the Women's Committee's work, especially praising my mother for her excellent arrangements and how comfortable it was. Finally, the principal gave each teacher a red envelope.

It was almost dark, and everyone chatted for a while before leaving, seemingly still wanting more. I secretly ran up to the third floor and watched them all leave before climbing out. I couldn't believe that all of this had happened right under my nose.

From that moment on, my attitude towards my mother, her colleagues, and school leaders underwent a complete change. It turns out that human desires can make people do anything unbelievable.
