(III)

After returning home from the night shift, Yi'er was still in class and hadn't come back yet. As her senior, Fang Run had tutored Yi'er in many subjects. Although Fang Run's grades were neither good nor bad when he was in school, he was an experienced person after all. Under his guidance, Yi'er's grades were among the best in the class.

The house was empty, except for a small sticker left by Yi'er on the refrigerator: "Little brother, remember to rest well when you get home. There's breakfast in the refrigerator." Seeing this, Fang Run felt a warmth in his heart. He thought that although he worked hard every day and had done something wrong to Yi'er last night, Yi'er still cared about him like this. Sigh, if he let her join the experimental group, he could collect the data himself, but what if Professor Lin really wanted to do double-blind experiments? Wouldn't he be worse than an animal? He should just forget about it. He couldn't tell her.

Sigh… Thinking of this, Fang Run felt extremely guilty. He silently took out his breakfast, heated it up in the microwave, ate a couple of bites hastily, and lay down on the bed without even bothering to clear the plate. Unconsciously, he gradually drifted off to sleep.
When he woke up, he found a soft body pressing down on him, holding him, and a soft hand caressing his body, unconsciously reaching inside his clothes, moving from top to bottom, slowly approaching his private parts.

He suddenly opened his eyes and saw Yi'er lying on top of him, wearing only a bathrobe, clearly showing that she wasn't wearing anything underneath. She grinned mischievously and said to him, "So tired last night? Did you go on a date with a nurse? The nurses in your department are all so alluring, I wonder if they'll steal you away? I'm just checking to see if you're still there~"
Fang Run was startled, but immediately pretended to be calm and started making excuses about various things in the ward. As they talked, Yi'er kissed him, and the two pressed tightly together, their tongues intertwining, entwined on the bed like that. Yi'er freed her hands to unbutton Fang Run's shirt, and Fang Run, impatient, quickly stripped off all his clothes, peeling back Yi'er's robe. Underneath, everything was revealed: smooth skin, soft breasts pressed against Fang Run's chest, making him even more proudly erect.

Fang Run gently lifted Yi'er, kissing her from head to toe, then gently placed her on the bed. His hands roamed over her silky skin, with only one destination in mind.

Having lived together for over half a year, they had developed a deeper understanding of each other's bodies, both acutely aware of each other's physical changes. When Yi'er tensed her body and raised her mons pubis, Fang Run promptly slipped his hand into her genitals, rubbing back and forth. She was already quite wet, so wet it seemed as if water would drip from his fingers.

Repeatedly, Fang Run touched Yi'er's already firm clitoris, circling and pressing it. Yi'er, under Fang Run's fingers, writhed incessantly, clinging to Fang Run's waist and arms, her face gradually flushing.
Suddenly, Yi'er let out a whimper, hugging Fang Run even tighter, then moaning, "No, no, no more..." Fang Run knew Yi'er was close to climax, so he sped up even more. Yi'er groaned, and soon her body went limp.

Looking at Fang Run with a flushed face, she said, "You're so naughty, it's my turn now!" She pushed Fang Run down, grasped his penis, and began stroking it back and forth, kissing and licking it from top to bottom, finally teasing the glans with the tip of her tongue. At this moment, Fang Run suddenly remembered his intimacy with Xiao Fei last night, and that he hadn't washed up yet, but it was too late.
Yi'er swallowed Fang Run's entire penis, sucking it a few times before spitting it out. It was clear that Yi'er had already sensed something was wrong. Before Fang Run could explain, Yi'er, seeing his expression, seemed to understand and started crying. She got dressed to leave, but Fang Run quickly grabbed her, apologizing profusely. He then recounted the events of the previous night in detail. The more he spoke, the harder Yi'er cried, and Fang Run didn't know how to comfort her.

Finally, Yi'er asked, "How was Xiao Fei's performance last night? Did you find it more enjoyable to sleep with her, or more comfortable with me?" Fang Run replied, "Of course, it was better with you, my wife! But last night, under the design of that project with my supervisor, it really felt different!" Hearing this, Yi'er burst into laughter through her tears and scolded, "You two, teacher and student, are disgusting! You always do these lewd things. Have you slept with every woman in your department?" 　　Fang

Run explained again, and then Yi'er said, "Since you say it's different, tell me about the content of your project!"

Knowing that everything was fine for the day, Fang Run touched Yi'er's vulva and said, "Then let's demonstrate again and you'll know!" Yi'er laughed and scolded, "You pervert, you bullied the little nurse and now you want to bully me too."
Fang Run said, "Whether it's comfortable or not, you'll know once you try!" So they went through the steps from last night again. Sure enough, having women point out their erogenous zones was not only efficient and accurate, but it also touched their sense of shame, making them more open. Yi'er was the same; soon she was panting heavily again, and before the experiment was even finished, she pulled Fang Run into her body.

Fang Run could also feel that Yi'er was different today. She had been too nervous last night and had ejaculated quickly, but today in his bed, she was in her element, playing with her nine shallow and one deep strokes until Yi'er cried out incessantly. In the end, both of them were covered in sweat and hugged each other, and Fang Run ejaculated inside Yi'er.

Slowly, slowly, Fang Run's penis softened and slid out. Yi'er kissed Fang Run's chest, touching his limp penis with her hand, and asked with a smile, "You said there's an experimental group, and your teacher asked you to introduce me to participate. Does he want to see us... uh-huh?" Fang Run was startled when he heard this, not knowing what to say, but his body was already aroused. His penis, which had just softened, began to swell again in Yi'er's hand, so hard that he felt a throbbing pain. Yi'er

clearly noticed this as well, and gently slapped Fang Run's penis, saying coquettishly, "You're so annoying, you want your teacher to see me naked too?" Fang Run laughed and said, "Not only do I want to see you naked, but I also want to fuck you good!" He then pressed Yi'er down beneath him, his erect penis aimed at Yi'er's vagina. The semen that had been ejaculated last time, mixed with her vaginal fluid, slowly flowed out of the opening. Fang Run thrust in all the way.

Yi'er looked at Fang Run and said with a wicked smile, "Teacher Lin, I've given myself to you like this, so you have to be nicer to my Fang Run!" Seeing his girlfriend's seductive demeanor, Fang Run got even more into character and laughed and scolded, "You little slut, how about we give your little Fang a son?"

Yi'er was already out of breath from Fang Run's rapid thrusting, panting as she said, "Okay, okay, come on! Come on!" The two of them embraced on the bed and had another big battle...

(To be continued)
(IV) After taking on the research project, Fang Run was also worried about how to find volunteers.

He also put up posters, and Xiao Fei helped him coax and trick a few girls into coming.

But only 4-5 girls came from beginning to end. Let's not talk about their looks, because Xiao Fei was always there to help record the data during the experiments, so nothing happened.

However, after a few experiments, Xiao Fei stared at Fang Run with dreamy eyes.

Fang Run also knew that he had gotten too close to this girl last time.

If they continued to entangle themselves, and Yi'er seemed to know about it, things could easily escalate into a major mess.

So, without saying anything more, she quickly collected and organized the information and went home.

There was nothing she could do; nobody's a saint. Every time Fang Run got off work, he was burning with lust. Seeing Yi'er, he wouldn't say much, just pull her to bed and start making love.

Yi'er knew the reason and understood Fang Run. She was even more pleased that Fang Run wasn't out there flirting with other women, but instead came home and dutifully paid the rent.

Each time this happened, Yi'er became increasingly interested in Fang Run's research. She was curious about the kind of environment and examination that could ignite such passion in her boyfriend.

She kept thinking how wonderful it would be if she could see it with Fang Run someday.

She subtly brought it up with Fang Run a few times, but he never gave a direct answer, and the matter was dropped.

Not long after, Yi'er still couldn't forget about it. Then, by chance, she saw Xiao Fei at a colleague's birthday party.

Seeing the girl who had once seduced her boyfriend, Yi'er suppressed her disgust and approached her. They quickly became acquainted.

Xiao Fei was also a very outgoing girl, usually quite unguarded. Seeing Fang Run's girlfriend, she thought that since she and Fang Run seemed to get along well, his girlfriend must be a good girl too.

Before long, emboldened by alcohol, the two girls began to talk more and more deeply.

Yi'er confessed that she knew about what happened between Xiao Fei and Fang Run that night. Xiao Fei blushed and told her about her feelings for Fang Run, even her secret relationship with Senior Brother Lu and Professor Lin's sexual harassment of her.

The two girls grew closer and even exchanged contact information.

Finally, Yi'er asked Xiao Fei to take her to visit Fang Run's experiment.

Xiao Fei, half-drunk, readily agreed.

Yi'er contacted Xiao Fei repeatedly, putting Xiao Fei in a difficult position. On one hand, she had promised Fang Run to keep the experiment confidential, and hospital regulations didn't allow it. On the other hand, this was Fang Run's girlfriend, and it wasn't really a big deal, plus she had promised her.

She wasn't sure if she should do this, and after a passionate encounter, she consulted Senior Brother Lu.

Senior Brother Lu, true to his reputation, had a lot of bad ideas. He suggested that Xiao Fei prepare a nurse's uniform for Yi'er, so she could sneak in, wear a mask, and not speak—Fang Run might not even recognize her.

If asked, she could say she was a nurse visiting for further training, interested in joining the group, and just wanted to observe.

Xiao Fei thought it was feasible and informed Yi'er.

The time was set for the next experiment.

Senior Brother Lu also had a vague feeling there would be a good show to watch. On the day of the experiment, he finished his surgery early and sat in Professor Lin's office watching the surveillance footage.

Fang Run, completely unaware of anything, arrived at the experimental room on time and, following procedure, repeated the countless teasing actions he had performed on the volunteer.

Xiao Fei was also recording data nearby; everything seemed normal.

Only, there was an additional visiting nurse present, a rather unreserved nurse.

When Fang Run finished the experiment and saw the volunteer off, Yi'er finally couldn't hold back any longer. She grabbed Fang Run from behind, and the two of them twisted into the darkroom. Yi'er gasped, "Husband, I want it."

Fang Run now understood what was going on.

He knew there were surveillance cameras, but he knew the footage was in Professor Lin's office. He knew this would be discovered, but he knew Professor Lin was never in the department in the afternoons; only he and Senior Brother Lu had the keys, and Senior Brother Lu was probably in surgery right now.

All he had to do was delete the footage afterward.

But to his utter surprise, Senior Brother Lu was watching intently behind the monitor.

Fang Run watched his girlfriend in her nurse's uniform, her legs pressed together, making her curves even more pronounced.

Having just witnessed a live sex scene, Yi'er's desire was completely ignited; she hadn't expected science to be so lewd.

Fang Run carried Yi'er to the bed in the darkroom's rest room, took off his white coat, and quickly removed Yi'er's nurse's skirt and stockings.

At this moment, Xiao Fei walked up from behind, laughing and saying, "So hasty? You came in your nurse's uniform, aren't you afraid of getting dirty?"

Fang Run turned around and found Xiao Fei already stripped down to her bra and panties, standing behind him.

Xiao Fei laughed and said, "What are you waiting for? Hurry up and lock the door, or someone will find out. I'll take care of your sister-in-law." Fang Run,

ignoring his loose belt, rushed to lock the door.

Xiao Fei went to the bedside and unbuttoned Yi'er's top and bra. Yi'er was also unable to control her desire; she had never been so closely touched by a woman before.

On the other end of the computer, Senior Brother Lu cursed, "Xiao Fei, you slut! You actually went to play threesome with Fang Run! See if I don't kill you next time!"

As a woman, Xiao Fei was very sensitive to Yi'er's erogenous zones. She stroked down Yi'er's body, sucking on every inch of her skin, each touch sending a shiver down Yi'er's spine.

Xiao Fei slid over Yi'er's pert, white breasts, over her flat, supple abdomen, over her snow-white, delicate thighs, finally reaching the secret garden between her legs.

At this moment, Fang Run returned after locking the door and saw Xiao Fei buried between Yi'er's legs, Yi'er looking dazed. He was instantly consumed by lust, walked behind Xiao Fei, and pulled down her panties.

Senior Brother Lu on the other end of the screen was also about to lose control. He thought to himself, "Fang Run, I'll give you a free ride today. Anyway, I'm tired of fucking Xiao Fei. I'll definitely get your wife someday."

As he watched, Senior Brother Lu couldn't help but take out his penis and start masturbating.

Fang Run pulled down Xiao Fei's panties, finding them already soaked. He touched between Xiao Fei's legs; they were warm and slippery, causing Xiao Fei to shudder.

Fang Run quickly stripped naked, placing his already erect penis between Xiao Fei's legs. The swollen glans rubbed back and forth at the entrance of Xiao Fei's vagina, refusing to penetrate. Xiao Fei struggled to get her buttocks to move, unable to get her vagina to grip Fang Run's penis.

Xiao Fei's licking became increasingly uninteresting. At this moment, Yi'er noticed her boyfriend had joined the fray.

She sat up, crawled behind Xiao Fei, and used her hand to pull Fang Run's wet penis from between Xiao Fei's legs. She took it into her mouth and stroked it for a while, then directly grasped the penis, aiming the glans at Xiao Fei's vagina.

Xiao Fei seemed to feel her vagina being pressed against, so she sat back, and with a "plop," swallowed Fang Run's entire penis.

She twisted her buttocks back and forth, cooperating with Fang Run's thrusts.

Seeing his girlfriend so openly inserting his penis into Xiao Fei's cunt, Fang Run reached between Yi'er's legs to fill the void. Fang Run's fingers circled back and forth around Yi'er's nipples. Soon, Yi'er joined Xiao Fei's moaning. First, she sat up and hugged Fang Run, passionately kissing him. Then, feeling it wasn't enough, she lay down parallel to Xiao Fei in front of Fang Run.

At this moment, Fang Run had two beautiful women in front of him, their wet genitals waiting for him. He didn't dare to neglect Yi'er, so he pulled his bright red penis out of Xiao Fei's cunt and thrust it into Yi'er's body. He then used two fingers to tease Xiao Fei's wet cunt. Listening

to the moans of the two beauties beneath him, what more could one ask for in life? Senior Brother Lu, watching from the other side, was even more lustful. He didn't care that this was his mentor's office and immediately started masturbating on the sofa.
