My romantic affair with my sister-in-law

My Romantic Affair with My Sister-in
-Law: The opening is another cliché, this is a true story… but it is indeed true. Aside from the names not being real and slight differences in the plot, it's basically true. Due to my limited writing skills, it's not very engaging. Just bear with it. I guess it will be better next time. Okay, enough chit-chat, let's get down to business. Let me introduce myself first.

I am a humble scholar, with a meager life. I can't say I'm handsome as a prince, but I'm probably close (just a little daydreaming)... As for my name, let's call me Wei. I work for a private company, and the pay is pretty good. My wife is the eldest child, with a younger brother and a younger sister. My brother is already married, and my sister is 22 years old. When I first met my sister-in-law, I didn't feel anything special, except that I was amazed by her ample bosom. She was only 1.62 meters tall, yet possessed a C-cup (at the time, it was just a guess, as I didn't have a precise idea), which was quite impressive. Later, after some research, I guessed it was genetic, since my mother-in-law also had a pair of large, firm breasts.

In the summer of 2008, my sister-in-law was transferred to a job near our home. Although the company provided dormitory accommodation, it lacked air conditioning, and we had to eat in the cafeteria. My wife, worried that her sister-in-law would suffer at the company, decided to have her stay with us. I was very reluctant at the time; we had just gotten married and hadn't even had enough of our life as a couple. The thought of someone suddenly coming over felt awkward. Before, when it was just the two of us, we could make love anywhere else after a quickie. But now my sister-in-law is here. Does that mean we're stuck in the bedroom, and even then, we have to be extremely careful? But you ca

n't fight city hall, and I have no choice but to obey unconditionally. The day my sister-in-law moved in, the weather was unbearably hot. Even though the air conditioning was on, I couldn't let the beautiful woman do all the moving herself. I was drenched in sweat, feeling incredibly uncomfortable. Only after we finished moving everything did I finally get a proper look at my sister-in-law. They say beautiful women are like a spring breeze, refreshing and invigorating. One glance at her and I felt a surge of energy; the heat instantly dissipated. My sister-in-law was wearing a low-cut t-shirt that day, revealing glimpses of her pink bra. Perhaps her breasts were quite large, or perhaps the shirt was too small, but they looked almost bursting out. I can't quite remember if she was wearing shorts or a skirt, because my attention was completely captivated by the White Rabbit candy. Everyone knows the Big Bad Wolf is a villain, but that's not entirely true. If it weren't for the allure of the White Rabbit candy, the Big Bad Wolf wouldn't be so evil. So, the culprit is the White Rabbit candy. "Brother-in-law!"

A clear voice interrupted my thoughts. "Oh, oh, Ying, sit down quickly, I'll get you an ice cream."

While speaking, I secretly glanced at my wife. Finding her attention completely on the TV, I secretly rejoiced.

After we got married, I took over all the cooking because my wife's cooking is really not that great. She usually just helps out, washing and preparing the vegetables. Naturally, the responsibility of cooking dinner fell to me. Maybe it was because my sister-in-law was visiting, and my wife wanted to show off her status at home. I called her several times to help prepare the vegetables, but she didn't budge. "Brother-in-law, let me help you,"

my sister-in-law appeared at that moment, probably noticing my embarrassment. She sat on a small stool and started preparing the vegetables for me. Since she had to bend down to get the vegetables, I was sitting opposite her, and I got a real treat for my eyes. Deep cleavage, soft skin, I couldn't even tell what color her nipples were. Several times I was just a hair's breadth away from seeing her nipples. But each time I was disappointed. Perhaps sensing my gaze, my sister-in-law looked up, meeting my lecherous eyes. I felt genuinely ashamed, realizing how wicked I was to try and take advantage of her (later I concluded, "Why let the good stuff go to outsiders? If I don't take it, I'm not even as good as an animal"). Surprisingly, she only gave me a slight glare, her face instantly turning red. That night's dinner was truly exceptional, perhaps due to the excitement.

After dinner, I urged my wife to go to sleep. Perhaps due to excessive hormones, my penis had been protesting more than once, so I needed to release it quickly, or I would definitely break down.

Back in the bedroom, I couldn't wait to pounce on her. My wife's figure was stunning, with curves in all the right places, especially her snow-white, large buttocks. Every time I climaxed, I wanted to ejaculate on her. My wife was also quick to heat up; after a few gentle caresses, she immediately mounted me. Perhaps because my sister was in the opposite room, her moans were much quieter than usual, but I did the opposite. I thrust as deep as I could each time. The sounds of flesh colliding filled the room.

"Oh, oh, I can't take it anymore, I can't take it anymore..."

my wife cried out, a mixture of pain and pleasure. But I couldn't let her go so easily, increasing the frequency of my thrusts. But my mind was filled with images of Xiaoshi, her deep cleavage... "Wei, you're amazing tonight, I really can't take it anymore, um, um, um..."

Just as I was thrusting intensely, I suddenly heard a slight noise outside. Since it was just the two of us at home before, we never closed the door when we made love. Maybe it was a habit, because this time I only slightly closed the door. My wife was probably too engrossed in it and didn't notice the door was closed. Obviously, the noise outside was coming from my sister-in-law.

"What was that noise?"

my wife asked. "Nothing,"

I laughed and said. "Honey, I'm coming," I said,

probably affected by the noise, and immediately ejaculated. "Ugh, go to sleep, you have to go to work tomorrow."

I don't know if my sister-in-law saw me, but with that question in mind, I drifted off to sleep.

When I woke up in the morning, my wife had already gone to work. My job is quite flexible. As long as you complete your tasks, your boss doesn't really care what you do each day. And my boss values me highly. Our relationship is very close. My wife's job is much more demanding; she only has holidays during the Lunar New Year, no weekends off. The nature of her job led to my affair with my sister-in-law. Well, I can't say my willpower wasn't strong enough.

"Brother-in-law, come over for dinner!"

My sister-in-law smiled at me when she saw me. There was nothing unusual on her face; it seemed she hadn't seen anything last night. I told myself that.

"Okay, I'll wash up."

Eating dinner was very awkward, which is my weakness. I always feel tongue-tied when I see beautiful women. I don't know what to say. I secretly glanced at my sister-in-law a few times during the meal. My sister-in-law has a round face with a slightly pointed chin, bordering on oval.

It's hard to describe, she's just very beautiful. Especially her lips; the two thin, small lips are playfully upturned like fresh fruit, very sexy. Seeing her lips, I thought how wonderful it would be to have her give me oral sex. They say you can tell the shape of a vagina and the amount of pubic hair by looking at the mouth. But I don't have that ability. I don't know what shape my sister-in-law's vagina is. Is it like my wife's, with thick pubic hair? Or is it sparse? Her hair was casually tied up, but it gave off a natural beauty. Maybe because she had just woken up, she hadn't changed yet, wearing last night's pajamas. Hmm, she probably wasn't wearing a bra underneath. But the pajamas were too loose. I couldn't see her nipples. Her nipples should still be pink.

I haven't heard my wife mention having a boyfriend. Sitting across from me, I could smell a faint fragrance; I couldn't tell if it was her natural scent or perfume.

"Ying, why aren't you at work?"

I asked, trying to make conversation. "The company gave me two days off to pack,"

my sister-in-law said. Then I fell into an awkward silence, not knowing what to say. Although I had lustful thoughts, I really didn't have the guts. After finishing my meal, I practically fled. Some readers might say that two days off is the perfect opportunity. I think those who think that have read too many erotic novels. Just touching her hand, or creating an environment where she immediately gives in. Pure nonsense. If things go wrong, it could lead to divorce and children breaking up, ugh. And we don't even have children yet. That would make it impossible for her to live a decent life.

Although I did have thoughts of possessing my sister-in-law at the time, it was just a thought; turning it into reality was something I might never have the chance of. Every time I saw my sister-in-law wearing revealing clothes, or looking alluring after a bath, I couldn't help but fantasize. Of course, I needed an outlet, which was to attack my wife repeatedly. My wife was exhausted and confused by me.

I don't know why my libido suddenly became so strong, and I was afraid of being heard by her sister, so I never dared to moan loudly. I felt this wasn't working, because I didn't know if my sister-in-law had feelings for me. I couldn't just sit and wait to die; if she did, then if I didn't act on it, wouldn't I really be worse than an animal? So I often did some outrageous things to test my sister-in-law's reaction.

One night, after dinner, my sister-in-law went to take a shower. I deliberately teased my wife and made her itchy. In fact, my wife's sexual desire is indeed very strong, but she is a bit conservative. I said to her, "Honey, I want it."

My wife rolled her eyes at me and said, "Pervert, just wait until you go to sleep."

That's okay. So I continued teasing, took out my penis, put it to my wife's mouth, and asked her to give me a blowjob. My wife had no choice but to compromise and said, "How about we go back to the bedroom."

I thought to myself, how can I do that? If I go back to the bedroom, it won't achieve my goal. I said, "I can't wait, just stay here."

"Ying is still in the bathroom."

I said, "It's too early to finish washing, let's solve it quickly."

So I lifted up my wife's pajamas and looked for the launch port. In fact, my wife didn't wear underwear after she changed into her pajamas when she got home. So I easily entered. I really don't want to describe my wife's lower body or the process of making love here. Because it's like eating a meal, it feels so ordinary. I'm not interested in describing it anymore, no matter how beautiful my wife is. I wonder if you, the reader, feel the same way.

However, this time my wife was more wet than before, probably because she felt her sister was in the room. She climaxed quickly. I think I was losing control, but I couldn't stop because my sister-in-law hadn't come out yet. About ten minutes passed. (Yes, exactly ten minutes. Not bragging, that's how it is. Haha.)

I heard the bathroom door open, but my wife was probably too excited to hear it. I pretended not to hear it and continued, not daring to look back. I was also afraid of embarrassment, but I knew my sister-in-law was right behind us, so I increased the intensity of my thrusting, trying to expose the point of contact to her. Stimulated, I finally couldn't hold back and ejaculated hard inside my wife. I heard my sister-in-law's footsteps move back into the bathroom. Afterwards, my wife quickly got up and cleaned up. A few minutes later, my sister-in-law came out. My wife pretended nothing had happened, saying, "Why did you take so long to shower? I was waiting to use the toilet."

She then hurried to the bathroom. I knew what she was thinking, because she still had millions of offspring inside her. She had to deal with it quickly. After my wife went in, my sister-in-law stared at me for a long time and said something that left me speechless. "Mind your image!"

I asked, feigning ignorance. "What do you mean, mind your image?"

My sister-in-law spat and fell silent, but I noticed her face was red. I couldn't tell if it was from taking a shower or something else entirely. It's impossible to verify now, because whenever I asked her later, she wouldn't say, only that I looked like a jerk.

After this incident, I concluded: at least my sister-in-law doesn't dislike me. Whether there's a chance remains to be seen. It seems that as a Communist Party member, my awareness is quite high; I know to reflect and summarize after each problem or difficulty. Thank you to the Party, thank you to the country. Without such good habits, there wouldn't be this progress.

After that, I frequently sought opportunities to contact my sister-in-law. Having read many novels, I summarized several strategies I could employ, such as drugging her. However, this is difficult to resolve once done. If she's willing, it's fine; but if she's unwilling, and especially if she's a chaste and virtuous woman, then I'm in for a rough time. Another method is to take the opportunity to touch her hand and observe her reaction. If it's good, I'll put my arm around her waist and kiss her. Then… if that feels inappropriate, I might watch a pornographic film together to see her reaction. Yes, that's what the novels say—put a few adult films on the computer, let your sister-in-law watch them, and then test her reaction.

That's it. This is the only feasible plan I can think of right now. Since we only have one computer at home, and it's in my bedroom, my sister-in-law often goes online there. So, as soon as my wife leaves on the weekend, I quickly put the hidden movie clips on the desktop, changing the names to random movie titles. I was hoping my sister-in-law would see them.

By the time my hair was almost white, it was already past 11 pm, and my sister-in-law finally got up, feeling annoyed. But as I hoped, in the afternoon, she went online. I pretended to go back to the bedroom to get something, to see if she was watching. Things didn't develop as I imagined, and there was no blushing or anything like in the novels. Later, I checked the playback and confirmed it was on, but only for a few seconds. I probably realized something was wrong and quickly turned it off. However, I still gained something. When I went back to the bedroom to see what she was doing, I saw what I'd been dreaming about. White and fleshy, I wanted nothing more than to ravage it. Because the neckline of her pajamas was quite low, I could see her tender nipples. Despite her large breasts, her nipples were actually quite small. I couldn't see them clearly, but that was enough. I don't usually like steamed buns, but from then on, I developed a liking for them, always squeezing them flat before eating. I only ate two at a time.

Ever since I saw my wife's younger sister's breasts that time, I've been obsessed. I even thought about buying a camera, but I really didn't know where to buy one; I always felt like most of them were scams. But that didn't stop me. I was like a fanatic at the time. Every time I saw my wife's younger sister, my eyes would burn with a burning light. Luckily, I didn't get a nosebleed, or I would have been in big trouble.

One weekend, my wife's younger brother, sister-in-law, and their daughter came to visit. Because they had drunk some alcohol at dinner, my wife didn't let her brother drive home. Getting caught driving under the influence would be a big problem.

Arranging for them to sleep became a problem, since we only have two beds. I originally planned to sleep on the sofa, with my wife and sister-in-law sharing a bed, and my brother, sister-in-law, and child sharing another. But my wife probably felt sorry for me and wouldn't let me sleep on the sofa. She said I could sleep with her and her sister-in-law, since we weren't strangers. What an understanding wife! I was so touched I cried, but I had to pretend I wasn't too happy. So my wife slept in the middle, and my sister-in-law and I slept on the sides.

I get really horny when I drink, even though it's bad for my health. I can't control myself. I'd barely lain down for a bit when my hands started wandering. And with my sister-in-law right there, I got even more excited. I reached for my wife's breasts, but she pulled them away. So, true to my Communist Party spirit, I kept harassing her. Maybe she was afraid of being discovered by her sister, so she just let it go. But once you get aroused, you can't control yourself. Finally, under my onslaught, my wife gave in. Her vulva was all wet. She turned her hips toward me, and I knew what she meant. I moved my penis to the cleft between her labia. I gently ground her breasts while one hand caressed her pert, pear-shaped breasts. My wife couldn't help but let out soft, lewd breaths. But they were very light. As I mentioned before, my wife doesn't wear underwear with her pajamas, which made my movements very convenient. My engorged penis heaved against her pubic hair. After a while, my wife couldn't take it anymore. She reached behind her and pressed her legs together forcefully. I knew she was close to climaxing, so I sped up. Just then, an untimely voice rang out. "Sis, are you feeling unwell?" My wife

pretended to be fine and said, "No."

But I could hear a tremor in her voice. After she finished speaking, I felt a gush of fluid well up from her lower body. My wife had an orgasm at that moment. Stimulated by the double stimulation, I also reached my climax. After a while, my wife pretended to go to the bathroom to clean up. As soon as she left, I sensed a different atmosphere, like the sweet feeling of first love. "Brother-in-law, really, I'm still here, couldn't you wait until I got back to do it?"

It turned out my sister-in-law knew, and it seemed she wasn't too bothered. Hearing this, I reached out and pinched her breast hard. Perhaps I pinched too hard, or perhaps she was startled by the sudden touch, because she cried out and slapped my hand hard

. "What's wrong?"

my wife asked, walking in. We both replied in unison, "Nothing." My wife didn't press further. The night passed peacefully.

Ever since that time I touched my sister-in-law, I've dreamt of touching her while sleeping every night. This dream torments me, leaving me physically and mentally exhausted, so I decided to take the risk. One night, after my wife had fallen asleep, I remember it was around midnight, I quietly got out of bed and cautiously made my way to my sister-in-law's room. I knew she didn't lock her door when she slept.

So I quietly opened the door, waited a while at the entrance, and when I heard no movement inside, I tiptoed in. My sister-in-law was sleeping peacefully. I walked to her bedside and reached out my hand towards her ample breasts. I gently touched them first; they were soft. My heart was pounding. I was worried that my sister-in-law would suddenly wake up, and I was also worried that my wife would find out I wasn't in the room and come out to use the bathroom. If she couldn't see me, it would be a big problem. But my sister-in-law's body was too tempting for me; I couldn't just be satisfied with a light touch. So I reached out my hand again. This time, when I placed my hand on her, I can't describe the feeling; it was like I melted. Actually, it only lasted about ten seconds before I quickly withdrew. Yes, I didn't dare go any further, because I still had my senses.

From then on, I would sneak into my sister-in-law's room late at night to caress her, trying to find my inner Mona Lisa. But even the most careful person can get their feet wet. Because I entered her so frequently, my sister-in-law noticed something was wrong. At that time, my wife was pregnant, and after discovering the pregnancy, she forbade any intimate contact with me. Even oral sex was forbidden.

This is why I entered her so frequently. That night, it was a rainy night; if it hadn't rained, there probably wouldn't have been any problems. I went into my sister-in-law's room as before. I placed my hand on her chest, caressing it and feeling the smoothness and softness of her breasts. Just as I was lost in this sensation, a hand suddenly grabbed mine. My mind went completely blank; I knew it was all over. But my sister-in-law didn't make a sound or do anything drastic. She just said two words: "Get out." I don't know how I got back to my own bed. I tossed and turned, unable to sleep, unable to understand what my sister-in-law meant. As dawn approached, it dawned on me: my sister-in-law liked me too. Looking back now, I realize how foolish I was. It was because my wife was pregnant, and my sister-in-law didn't want to upset her, fearing it would affect the baby. However, it was precisely because of my mistaken thinking that I ended up with my sister-in-law by a twist of fate—but that's a story for another time.

The next morning, my sister-in-law acted as if nothing had happened, chatting and laughing as usual, which only reinforced my belief that she liked me. After breakfast, my sister-in-law changed her clothes to prepare for work. She wore a business suit. She had a very mature, married woman's air about her—a light blue mini-skirt and sheer, flesh-colored stockings, I couldn't tell if they were half-length or a bodysuit, and I really wanted to touch them. I wouldn't have dared to do this before, but since what happened last night, I've become bolder. My sister-in-law was putting on her shoes, sticking her butt out as she did so; it looked very full, especially with the stockings, making it even more irresistible. I couldn't see any panty lines, so was she wearing a thong? At that moment, I was already driven by lust. I pretended to put on my shoes too, and then, as if I was about to stumble, I grabbed her buttocks. My sister-in-law reflexively straightened up immediately. I smiled shamelessly, and she walked away as if nothing had happened.

After she left, I quickly went into her room and finally found her underwear and bra in the drawer. The underwear was Reese's, some were even thongs. Why hadn't I thought to look at underwear before? I put the underwear over my penis, fantasizing about my sister-in-law, and ejaculated on her. After finishing, I quickly wiped myself and put it back in the drawer. That evening at dinner, while my wife was out, my sister-in-law suddenly asked me, "Did you go to my room?"

"No, how could I?"

I replied guiltily. "Don't think I don't know what you did. If you do that again, I'll tell my sister."

It seemed she still had some reservations, but at this point, I wasn't scared anymore. Because she had tolerated me time and time again, if I turned against her the first time, there probably wouldn't be a future. Since that was the case, I might as well go all the way and sleep with her that night, I thought to myself.

That night, after my wife fell asleep, I went into my sister-in-law's room again. Yes, I didn't lock the door. Maybe she thought I wouldn't dare to go back.

I didn't play with her breasts anymore, but instead chose to directly attack her pubic hair. Because I was afraid of waking her up, I gently lifted her nightgown. Sure enough, she was wearing a thong. The small piece of fabric couldn't cover up her pubic hair at all. Well, I can't say it was a pubic hair, because her pubic hair wasn't particularly thick; it was sparse. I gently pressed her clitoris with my hand. The thong felt a bit restrictive, so I went to the living room and got a pair of scissors. I cut the small ligament shorter, and then I couldn't wait to lie down on it and smell it deeply. It smelled nice. I gently parted her labia. Her labia were rosy in color, completely different from her sister's. My wife's labia were thin, wrinkled, and a bit dark. The difference was huge.

I stuck out my tongue and gently licked her clitoris and labia. My sister-in-law made a soft "hmm" sound, which startled me. I stopped, but after a while there was no further reaction; she was probably having a wet dream. I wondered if the object of her dream was me. I increased the speed of my licking. Then, my sister-in-law's body moved slightly. I inserted my fingers into her vagina, teasing the delicate flesh at the vaginal opening. Her labia minora began to naturally separate and turn to the sides. At that moment, some fluid flowed out. Seeing that the time was right, I quickly aimed my already erect penis at her vagina. I knew my sister-in-law didn't have a boyfriend, so I figured she was probably a virgin. I carefully moved forward... Huh?

Without resistance, I continued forward, most of my penis already inside. It seemed my sister-in-law wasn't a virgin anymore. I felt a mix of disappointment and joy. If she wasn't a virgin, my guilt would be less, but the fact that she wasn't made me curse inwardly who had taken her virginity. But this wasn't the time to think about that. I moved my body slowly, so tired, so very tired, afraid of waking her. But she did wake up. As soon as she opened her eyes and saw me, she immediately pushed me away. Seeing that she was awake, I didn't need to be careful anymore. I lowered my hips, penetrating her completely. "Ah,"

my sister-in-law let out a soft moan, not very loud. It seemed she was still hesitant, afraid her sister would hear. Since that was the case, I wasn't afraid anymore and increased the speed of my thrusts. "No, brother-in-law, no!"

my sister-in-law pleaded, her voice low as she pushed against my arms and chest, perhaps trying to avoid making noise if she hit me. I didn't let her continue, my lips chasing her retreating mouth while my hands kneaded her breasts and nipples. I pulled her loose clothes up, and when I saw her firm pink nipples and smooth, white breasts, I didn't hesitate to bite them, my tongue quickly licking her sensitive nipples. She cried out in stimulation. "No, no! Brother-in-law, my sister is next door, I can't let her down."

Hearing this, I became even more enthusiastic, gently biting her nipple with my teeth. "Ah,"

my sister-in-law was already breathing heavily, repeatedly saying, "No, no,"

but her hands were no longer resisting. She was still occasionally stroking my back; she seemed to have broken down. I knew I couldn't let my guard down now; I had to completely conquer her. I sped up, making slapping sounds. Suddenly, she pressed down on my buttocks and said, "Keep it down, don't let your older sister hear."

Upon hearing this, I almost lost control and ejaculated. It seemed she had accepted, at least temporarily, so I reached out to take off her pajamas. My sister-in-law obediently lifted her back and took them off. I had been so focused on forcing myself on her that I hadn't properly appreciated her breasts. Since the lights were off, I couldn't admire them, so I could only feel them with my hands. While kneading her breasts, my penis thrust rapidly inside her vagina. After dozens of rapid thrusts, her body trembled, and she tightly hugged my neck. "Ah,"

I cried out in pain. My sister-in-law bit me during her orgasm! Oh no, what if my wife sees this tomorrow? Never mind, I'll deal with tomorrow's problems tomorrow. As she tensed up, experiencing that excruciating, bone-melting pleasure, I slowed down a bit and thrust deeply into her vagina, feeling the slippery, hot flesh, the sensation of her vagina constantly writhing due to her orgasm. I thrust heavily into her flower, and after the first orgasm, the second came quickly. This time, having learned from the first experience, I didn't let my sister-in-law bite me. After the orgasm, my sister-in-law said, "Let's not do this anymore. I'm sorry to my sister."

I knew it was too late to say anything now, because she was awake, and I was worried my wife would find out I hadn't been home for a long time, so I hurriedly ran back to the bedroom. Fortunately, my wife was sleeping soundly.

"Sister, I think I should move back to the company dorms. Work is really busy right now, sometimes I have to work late, and it's inconvenient to come home at night."

I had just woken up when I heard my sister-in-law talking to my wife. I knew she was making excuses to avoid me, so I quickly got out of bed and said, "You shouldn't stay at the company dorms. Your sister is pregnant, you can take care of her if you stay home."

"Yes, Ying, don't stay at the company dorms. There's no air conditioning in the company dorms. If you come home late, I'll have your brother-in-law pick you up,"

my wife chimed in. Seeing there was no other way, my sister-in-law didn't insist anymore. But for the next few days, she kept avoiding me, leaving early every morning and locking herself in her room at night. And she never let me pick her up even once. It was really frustrating.

The opening is another cliché: this is a true story… but it really is true. Aside from the names not being real and slight differences in the plot, it's basically true. Due to my limited writing skills, it's not very engaging. Just bear with it. I expect it will be better next time. Okay, enough chit-chat, let's get down to business. Let me introduce myself first.

I am a humble scholar, with a meager life. I wouldn't call myself handsome or as dashing as Pan An, but I'd say I'm only a little bit (just kidding)... As for my name, let's call me Wei. I work for a private company, and the pay is pretty good. My wife is the eldest child in her family, with a younger brother and a younger sister. My brother is already married, and my sister is 22 years old. When I first met my sister-in-law, I didn't feel anything special, except that I was amazed by her ample bosom. She was only 1.62 meters tall, yet possessed a C-cup (at the time, it was just a guess, as I didn't have a precise idea), which was quite impressive. Later, after some research, I guessed it was genetic, since my mother-in-law also had a pair of large, firm breasts.

In the summer of 2008, my sister-in-law was transferred to a job near our home. Although the company provided dormitory accommodation, it lacked air conditioning, and we had to eat in the cafeteria. My wife, worried that her sister-in-law would suffer at the company, decided to have her stay with us. I was very reluctant at the time; we had just gotten married and hadn't even had enough of our life as a couple. The thought of someone suddenly coming over felt awkward. Before, when it was just the two of us, we could make love anywhere else after a quickie. But now my sister-in-law is here. Does that mean we're stuck in the bedroom, and even then, we have to be extremely careful? But you ca

n't fight city hall, and I have no choice but to obey unconditionally. The day my sister-in-law moved in, the weather was unbearably hot. Even though the air conditioning was on, I couldn't let the beautiful woman do all the moving herself. I was drenched in sweat, feeling incredibly uncomfortable. Only after we finished moving everything did I finally get a proper look at my sister-in-law. They say beautiful women are like a spring breeze, refreshing and invigorating. One glance at her and I felt a surge of energy; the heat instantly dissipated. My sister-in-law was wearing a low-cut t-shirt that day, revealing glimpses of her pink bra. Perhaps her breasts were quite large, or perhaps the shirt was too small, but they looked almost bursting out. I can't quite remember if she was wearing shorts or a skirt, because my attention was completely captivated by the White Rabbit candy. Everyone knows the Big Bad Wolf is a villain, but that's not entirely true. If it weren't for the allure of the White Rabbit candy, the Big Bad Wolf wouldn't be so evil. So, the culprit is the White Rabbit candy. "Brother-in-law!"

A clear voice interrupted my thoughts. "Oh, oh, Ying, sit down quickly, I'll get you an ice cream."

While speaking, I secretly glanced at my wife. Finding her attention completely on the TV, I secretly rejoiced.

After we got married, I took over all the cooking because my wife's cooking is really not that great. She usually just helps out, washing and preparing the vegetables. Naturally, the responsibility of cooking dinner fell to me. Maybe it was because my sister-in-law was visiting, and my wife wanted to show off her status at home. I called her several times to help prepare the vegetables, but she didn't budge. "Brother-in-law, let me help you,"

my sister-in-law appeared at that moment, probably noticing my embarrassment. She sat on a small stool and started preparing the vegetables for me. Since she had to bend down to get the vegetables, I was sitting opposite her, and I got a real treat for my eyes. Deep cleavage, soft skin, I couldn't even tell what color her nipples were. Several times I was just a hair's breadth away from seeing her nipples. But each time I was disappointed. Perhaps sensing my gaze, my sister-in-law looked up, meeting my lecherous eyes. I felt genuinely ashamed, realizing how wicked I was to try and take advantage of her (later I concluded, "Why let the good stuff go to outsiders? If I don't take it, I'm not even as good as an animal"). Surprisingly, she only gave me a slight glare, her face instantly turning red. That night's dinner was truly exceptional, perhaps due to the excitement.

After dinner, I urged my wife to go to sleep. Perhaps due to excessive hormones, my penis had been protesting more than once, so I needed to release it quickly, or I would definitely break down.

Back in the bedroom, I couldn't wait to pounce on her. My wife's figure was stunning, with curves in all the right places, especially her snow-white, large buttocks. Every time I climaxed, I wanted to ejaculate on her. My wife was also quick to heat up; after a few gentle caresses, she immediately mounted me. Perhaps because my sister was in the opposite room, her moans were much quieter than usual, but I did the opposite. I thrust as deep as I could each time. The sounds of flesh colliding filled the room.

"Oh, oh, I can't take it anymore, I can't take it anymore..."

my wife cried out, a mixture of pain and pleasure. But I couldn't let her go so easily, increasing the frequency of my thrusts. But my mind was filled with images of Xiaoshi, her deep cleavage... "Wei, you're amazing tonight, I really can't take it anymore, um, um, um..."

Just as I was thrusting intensely, I suddenly heard a slight noise outside. Since it was just the two of us at home before, we never closed the door when we made love. Maybe it was a habit, because this time I only slightly closed the door. My wife was probably too engrossed in it and didn't notice the door was closed. Clearly, the noise outside was coming from my sister-in-law.

"What was that noise?"

my wife asked. "Nothing,"

I chuckled and said. "Honey, I'm coming," I said,

probably affected by the noise, and immediately ejaculated. "Ugh, go to sleep, you have to go to work tomorrow."

I don't know if my sister-in-law saw it, but with that question in mind, I drifted off to sleep.

When I woke up this morning, my wife had already gone to work. My job is quite flexible. As long as I complete the tasks, my boss doesn't really care what I do each day. And my supervisor values me highly. We have a very good relationship. My wife's job is much more tiring. Except for the Lunar New Year holiday, she doesn't have any holidays, not even weekends. The nature of her job led to my affair with my sister-in-law. Well, I can't say my willpower wasn't strong enough.

"Brother-in-law, come over for dinner!"

My sister-in-law smiled at me when she saw me. There was nothing wrong with her face; it seemed she hadn't seen anything last night. I told myself that.

"Okay, I'll wash up."

Eating dinner was very awkward; that's my weakness. I always feel tongue-tied when I see beautiful women. I don't know what to say. While eating, I secretly glanced at my sister-in-law a few times. She has a round face with a slightly pointed chin, bordering on oval.

I can't describe it, she's just very beautiful. Especially her lips; the two thin, small lips are playfully upturned like fresh fruit, very sexy. Seeing her lips, I thought how wonderful it would be to have her give me oral sex. They say you can tell the shape of a vagina and the amount of pubic hair by looking at the mouth. But I don't have that ability. I don't know what shape my sister-in-law's vagina is. Is it like my wife's, with thick pubic hair? Or is it sparse? Her hair was casually tied up, but it gave off a natural beauty. Perhaps because she had just woken up, she hadn't changed yet, still wearing last night's pajamas. Hmm, she probably wasn't wearing a bra underneath. But the pajamas were too loose. I couldn't see her nipples. They should still be pink.

I hadn't heard my wife mention having a boyfriend. Sitting across from me, I could smell a faint fragrance, I couldn't tell if it was her natural scent or perfume.

"Ying, why aren't you at work?"

I asked, trying to make conversation. "The company gave me two days off to pack,"

my sister-in-law said. Then I fell into an awkward silence, not knowing what to say. Although I had lustful thoughts, I really didn't have the guts. After dinner, I practically fled. Some readers might say, "Two days off is the perfect opportunity!" I think people who think like that have read too many erotic novels. Just touching her hand, or creating an environment where she'd immediately give in—it's pure nonsense. If things go wrong, it could lead to divorce and children breaking up, ugh. And we didn't even have children yet. That would make it impossible for her to live a decent life.

Although I did have thoughts of possessing my sister-in-law at the time, it was just a thought; it might never become reality. Every time I saw my sister-in-law in revealing clothes, or looking so alluring after a bath, I couldn't help but fantasize. Of course, I needed an outlet, which was to attack my wife repeatedly. My wife was exhausted both physically and mentally, and also inexplicably...

I don't know why my libido suddenly became so strong, and I was afraid her sister would hear, so I never dared to moan loudly. I felt this wasn't working, because I didn't know if my sister-in-law had feelings for me. I couldn't just sit and wait; if she did, then not taking action would make me less than an animal. So I often did some outrageous things to test her reaction.

One evening, after dinner, my sister-in-law went to take a shower, and I deliberately teased my wife, making her itchy. Actually, my wife has a very strong sex drive, she's just a bit conservative. I said to her, "Honey, I want it."

My wife rolled her eyes at me and said, "You lecher, wait until bedtime."

How could I let that happen? So I continued teasing, took out my penis, put it to my wife's mouth, and asked her to give me a blowjob. My wife had no choice but to compromise and said, "How about we go back to the bedroom."

I thought to myself, how can I do that? If I go back to the bedroom, it won't achieve my goal. I said, "I can't wait, just stay here."

"Ying is still in the bathroom."

I said, "It's too early to finish washing, let's solve it quickly."

So I lifted up my wife's pajamas and looked for the launch port. In fact, my wife didn't wear underwear after she changed into her pajamas when she got home. So I entered easily. I really don’t want to describe my wife’s lower body and the process of making love here. Because just like eating, it already feels ordinary. I no longer have the interest to describe it. No matter how beautiful my wife is. I don’t know if you, reader, have the same idea as me.

This time, however, my wife produced more fluid than before, probably because she sensed her sister was in the room. She climaxed quickly. I think I was losing control, but I couldn't stop because my sister-in-law hadn't come out yet. About ten minutes passed. (Yes, exactly ten minutes. Not bragging, that's how it is. Haha.)

I heard the bathroom door open, but my wife was probably too excited to hear it. I pretended not to hear and continued, not daring to look back. I was also afraid of embarrassment, but I knew my sister-in-law was behind us, so I increased the intensity of my thrusts, trying to expose the point of contact to her. At this point, stimulated, I finally couldn't hold back anymore and ejaculated hard inside my wife. I heard my sister-in-law's footsteps move back into the bathroom. Afterwards, my wife quickly got up and cleaned up the battlefield. A few minutes later, my wife's younger sister came out. My wife pretended nothing had happened and said, "Why did you take so long to shower? I was waiting to use the bathroom."

She then hurried to the bathroom. I knew what she was thinking, because she still had millions of offspring inside her. She had to deal with it quickly. After my wife went in, my wife's younger sister stared at me for a long time before saying something that left me speechless. "Mind your image!"

I asked, feigning ignorance, "What do you mean, mind your image?"

My wife's younger sister spat and didn't say anything more, but I noticed her face was red. I didn't know if it was because of the shower or something else. It's impossible to verify now, because whenever I asked her later, she wouldn't say anything, only that I looked like a jerk.

After this incident, I concluded: at least my wife's younger sister doesn't dislike me. Whether there will be an opportunity remains to be seen. It seems that as a Communist Party member, my awareness is quite high; I know that every time there's a problem or difficulty, I should summarize and reflect on it. Thanks to the Party and the country; without such good habits, there wouldn't be this development.

Afterwards, I frequently sought various opportunities to contact my sister-in-law. Having read many novels, I summarized several strategies that could be implemented, such as drugging her. This would be difficult to resolve afterward. If she's willing, it's fine; if not, and especially if she's a chaste and virtuous woman, then I'd be in for a rough time. Another method is to take the opportunity to touch her hand and see her reaction. If it's good, I'll put my arm around her waist and kiss her. Then… if that feels inappropriate, I'll watch a pornographic film together and see her reaction. Well, that's what they say in novels: put a few adult movies on the computer, let your sister-in-law watch them, and see how she reacts.

That's it. It's the only feasible idea I can think of right now. Since we only have one computer at home, and it's in my bedroom, and my sister-in-law often goes online, I'll wait until the weekend, as soon as my wife leaves, and quickly put the hidden adult movies on the desktop. Of course, I'll change the names—just a few random movie titles. Then I'll eagerly wait for my sister-in-law to see them.

By the time my hair is almost white, it's already past 11 pm, and my sister-in-law finally gets up. I'm annoyed. But as I hoped, in the afternoon, my sister-in-law goes online. I'll pretend to go back to the bedroom to get something, to see if she's watching anything. Things didn't develop as I imagined, nor did it unfold like in the novels—no blushing cheeks, nothing like that. Later, I checked the playback; it was indeed on, but only for a few seconds. Perhaps realizing something was wrong, I quickly turned it off. However, there was still something I gained. When I went back to the bedroom to see what she was doing, I saw what I'd been dreaming about. White and fleshy, I wanted nothing more than to ravage it. Because the neckline of her pajamas was quite low, I could see her tender nipples. Despite her large breasts, her nipples were actually quite small. I couldn't see them clearly, but that was enough. I don't usually like steamed buns, but from then on, I developed a liking for them, always squeezing them flat before eating. I only ate two at a time.

Ever since I saw my wife's younger sister's breasts that time, I've been obsessed. I even thought about buying a camera, but I really didn't know where to buy one; I always felt like most of them were scams. But that didn't stop me. I was like a fanatic at the time. Every time I saw my wife's younger sister, my eyes would burn with a burning light. Luckily, I didn't get a nosebleed, or I would have been in big trouble.

One weekend, my wife's younger brother, sister-in-law, and their daughter came to visit. Because they had drunk some alcohol at dinner, my wife didn't let her brother drive home. Getting caught driving under the influence would be a big problem.

Arranging for them to sleep became a problem, since we only have two beds. I originally planned to sleep on the sofa, with my wife and sister-in-law sharing a bed, and my brother, sister-in-law, and child sharing another. But my wife probably felt sorry for me and wouldn't let me sleep on the sofa. She said I could sleep with her and her sister-in-law, since we weren't strangers. What an understanding wife! I was so touched I cried, but I had to pretend I wasn't too happy. So my wife slept in the middle, and my sister-in-law and I slept on the sides.

I get really horny when I drink, even though it's bad for my health. I can't control myself. I'd barely lain down for a bit when my hands started wandering. And with my sister-in-law right there, I got even more excited. I reached for my wife's breasts, but she pulled them away. So, true to my Communist Party spirit, I kept harassing her. Maybe she was afraid of being discovered by her sister, so she just let it go. But once you get aroused, you can't control yourself. Finally, under my onslaught, my wife gave in. Her vulva was all wet. She turned her hips toward me, and I knew what she meant. I moved my penis to the cleft between her labia. I gently ground her breasts while one hand caressed her pert, pear-shaped breasts. My wife couldn't help but let out soft, lewd breaths. But they were very light. As I mentioned before, my wife doesn't wear underwear with her pajamas, which made my movements very convenient. My engorged penis heaved against her pubic hair. After a while, my wife couldn't take it anymore. She reached behind her and pressed her legs together forcefully. I knew she was close to climaxing, so I sped up. Just then, an untimely voice rang out. "Sis, are you feeling unwell?" My wife

pretended to be fine and said, "No."

But I could hear a tremor in her voice. After she finished speaking, I felt a gush of fluid well up from her lower body. My wife had an orgasm at that moment. Stimulated by the double stimulation, I also reached my climax. After a while, my wife pretended to go to the bathroom to clean up. As soon as she left, I sensed a change in the atmosphere, like the sweet feeling of first love. "Brother-in-law, really, I'm still here, couldn't you wait until I got back to do it?"

It turned out my sister-in-law knew, and it seemed she wasn't too bothered. Hearing this, I reached out and pinched her breast hard. Maybe I pinched it too hard, or maybe she was startled by the sudden touch, because she cried out and then slapped my hand with a "smack

." "What's wrong?"

my wife asked as she walked in. We both answered in unison, "Nothing." My wife didn't ask any further questions. The night passed peacefully.

Ever since that time I touched my sister-in-law, I've dreamt every night about touching her while she sleeps. This dream torments me, leaving me physically and mentally exhausted, so I decided to take a risk. One night, after my wife had fallen asleep, I remember it was around midnight. I quietly got out of bed and carefully made my way to my sister-in-law's room, knowing she didn't lock her door when she slept.

So I quietly opened the door and waited a while. Hearing no movement inside, I tiptoed in. My sister-in-law was sleeping peacefully. I walked to her bedside and reached out my hand towards her ample breasts. I gently touched them; they were soft. My heart pounded. I was worried she might wake up suddenly, and I was also worried my wife might find me out of the room and come to the bathroom. If she couldn't see me, it would be a huge problem. But my sister-in-law's body was too tempting; I couldn't be satisfied with just a light touch. So I reached out again. This time, I covered them with my hand. I can't describe the feeling; I felt like I had melted. In reality, it only lasted ten seconds before I quickly retreated. Yes, I didn't dare to continue, because I still had my senses.

From then on, I would sneak into my sister-in-law's room late at night to caress her, trying to find my inner Mona Lisa. But even the most careful person can get their shoes wet. Because I entered so frequently, my sister-in-law noticed something was wrong. At that time, my wife was pregnant, and after discovering the pregnancy, she forbade any intimate contact with me. Even oral sex was forbidden.

This was why I entered so frequently. That night, it was a rainy night; if it hadn't rained, there probably wouldn't have been any problems. I entered my sister-in-law's room as before. I placed my hand on her chest. I caressed her, feeling the delicate softness of her breasts. Just as I was lost in this sensation, a hand suddenly grabbed mine. My mind went completely blank; I knew it was all over. But my sister-in-law didn't make a sound or do anything drastic. She simply said two words: "Get out." I don't know how I got back to my bed. I tossed and turned, unable to sleep, unable to understand what my sister-in-law meant. As dawn approached, it dawned on me: my sister-in-law liked me too. Looking back, I realize how foolish I was. It was because my wife was pregnant, and my sister-in-law didn't want to upset her, fearing it would affect the baby. But because of my mistaken thinking, I ended up with my sister-in-law by accident—but that's a story for another time.

The next morning, my sister-in-law acted as if nothing had happened, chatting and laughing as usual. This reinforced my belief that she liked me. After breakfast, she changed into a business suit. She had a very mature, married air about her, wearing a light blue mini skirt and sheer, flesh-colored stockings that were either cropped or bodysuits. I really wanted to touch them. I wouldn't have dared to do this before, but since what happened last night, I've become bolder. My sister-in-law was putting on her shoes, sticking her butt out as she did so; it looked very full, especially with the stockings, making it even more irresistible. I couldn't see any panty lines, so was she wearing a thong? At that moment, I was already driven by lust. I pretended to put on my shoes too, and then, as if I was about to stumble, I grabbed her buttocks. My sister-in-law reflexively straightened up immediately. I smiled shamelessly, and she walked away as if nothing had happened.

After she left, I quickly went into her room and finally found her underwear and bra in the drawer. The underwear was Reese's, some were even thongs. Why hadn't I thought to look at underwear before? I put the underwear over my penis, fantasizing about my sister-in-law, and ejaculated on her. After finishing, I quickly wiped myself and put it back in the drawer. That evening at dinner, while my wife was out, my sister-in-law suddenly asked me, "Did you go to my room?"

"No, how could I?"

I replied guiltily. "Don't think I don't know what you did. If you do that again, I'll tell my sister."

It seemed she still had some reservations, but at this point, I wasn't scared anymore. Because she had tolerated me time and time again, if I turned against her the first time, there probably wouldn't be a future. Since that was the case, I might as well go all the way and sleep with her that night, I thought to myself.

That night, after my wife fell asleep, I went into my sister-in-law's room again. Yes, I didn't lock the door. Maybe she thought I wouldn't dare to go back.

I didn't play with her breasts anymore, but instead chose to directly attack her pubic hair. Because I was afraid of waking her up, I gently lifted her nightgown. Sure enough, she was wearing a thong. The small piece of fabric couldn't cover up her pubic hair at all. Well, I can't say it was a pubic hair, because her pubic hair wasn't particularly thick; it was sparse. I gently pressed her clitoris with my hand. The thong felt a bit restrictive, so I went to the living room and got a pair of scissors. I cut the small ligament shorter, and then I couldn't wait to lie down on it and smell it deeply. It smelled nice. I gently parted her labia. Her labia were rosy in color, completely different from her sister's. My wife's labia were thin, wrinkled, and a bit dark. The difference was huge.

I stuck out my tongue and gently licked her clitoris and labia. My sister-in-law made a soft "hmm" sound, which startled me. I stopped, but after a while there was no further reaction; she was probably having a wet dream. I wondered if the object of her dream was me. I increased the speed of my licking. Then, my sister-in-law's body moved slightly. I inserted my fingers into her vagina, teasing the delicate flesh at the vaginal opening. Her labia minora began to naturally separate and turn to the sides. At that moment, some fluid flowed out. Seeing that the time was right, I quickly aimed my already erect penis at her vagina. I knew my sister-in-law didn't have a boyfriend, so I figured she was probably a virgin. I carefully moved forward... Huh?

Without resistance, I continued forward, most of my penis already inside. It seemed my sister-in-law wasn't a virgin anymore. I felt a mix of disappointment and joy. If she wasn't a virgin, my guilt would be less, but the fact that she wasn't made me curse inwardly who had taken her virginity. But this wasn't the time to think about that. I moved my body slowly, so tired, so very tired, afraid of waking her. But she did wake up. As soon as she opened her eyes and saw me, she immediately pushed me away. Seeing that she was awake, I didn't need to be careful anymore. I lowered my hips, penetrating her completely. "Ah,"

my sister-in-law let out a soft moan, not very loud. It seemed she was still hesitant, afraid her sister would hear. Since that was the case, I wasn't afraid anymore and increased the speed of my thrusts. "No, brother-in-law, no!"

my sister-in-law pleaded, her voice low as she pushed against my arms and chest, perhaps trying to avoid making noise if she hit me. I didn't let her continue, my lips chasing her retreating mouth while my hands kneaded her breasts and nipples. I pulled her loose clothes up, and when I saw her firm pink nipples and smooth, white breasts, I didn't hesitate to bite them, my tongue quickly licking her sensitive nipples. She cried out in stimulation. "No, no! Brother-in-law, my sister is next door, I can't let her down."

Hearing this, I became even more enthusiastic, gently biting her nipple with my teeth. "Ah,"

my sister-in-law was already breathing heavily, repeatedly saying, "No, no."

But her hands were no longer resisting. She was also occasionally stroking my back, it seemed she had already broken down. I knew I couldn't be careless now, I had to completely conquer her, I sped up, making slapping sounds. At this moment, she suddenly pressed down on my buttocks and said, "Keep it down, don't let your sister hear." When

I heard that, I almost lost control and ejaculated. It seemed she had accepted, at least temporarily, so I reached out to take off her pajamas, and my sister-in-law cooperated by lifting her back and taking off her pajamas. I was so focused on forcing myself on her that I hadn't had a chance to properly appreciate my sister-in-law's breasts. Since the lights were off, I couldn't see them, so I had to use my hands. While kneading her breasts, my penis thrust rapidly inside her vagina. After dozens of rapid thrusts, my sister-in-law's body trembled, and she tightly hugged my neck. "Ah,"

I cried out in pain. My sister-in-law bit me during her orgasm! Oh no, what if my wife sees this tomorrow? Never mind, I'll deal with tomorrow's problems tomorrow. As she tensed up, experiencing that excruciating, bone-melting pleasure, I slowed down a bit and thrust deeply into her vagina, feeling the slippery, hot flesh, the sensation of her vagina constantly writhing due to her orgasm. She thrust deeply into my flower, again and again. After the first orgasm, the second came quickly. This time, having learned from the first experience, I didn't let my sister-in-law bite me. After the orgasm, my sister-in-law said, "Let's not do this anymore. I'm sorry to my sister."

I knew it was too late to say anything now, because she was already sober, and I was also worried that my wife would find out I hadn't been home for a long time, so I hurriedly ran back to the bedroom. Fortunately, my wife was sleeping soundly.

"Sister, I'll move back to the company residence. Work is quite busy now, and sometimes I need to work overtime until very late, which is quite troublesome to come home at night."

I had just woken up from my sleep when I heard my sister-in-law talking to my wife. I knew my sister-in-law was just making excuses to avoid me, so I quickly got out of bed and said, "You shouldn't stay at the company anymore. Your sister is pregnant; you can take care of her if you stay home."

"Yes, Ying, don't stay at the company. The company dormitory doesn't have air conditioning. If you come back late, I'll have your brother-in-law pick you up,"

my wife chimed in. Seeing that she had no choice, my sister-in-law didn't insist anymore. But for the next few days, she always avoided me, leaving early every morning and locking herself in her room at night. And she never let me pick her up even once. It was really frustrating.
