Chapter 1 of The Experiment

Peter and Alex were deeply in love. They met during their sophomore year of college and became an item by their junior year. Peter admired Alex's witty, lively nature, as well as her adorable form and curvy rear end. Alex was drawn to Peter's handsome face and his intelligence. She recognized his potential for success in the future.

Also during Alex's sophomore year, Peter maintained a playful relationship with Stacey, her best friend and former roommate. They spent the entire summer together in their suite, and Stacey frequently found herself flirting with him. Despite Peter's lack of understanding of social cues, he was mostly unaware of this.

Meanwhile, Stacey, who routinely had intercourse with members of the basketball and football teams, enjoyed mocking Peter, teasing him about his short stature and effeminate appearance, and bragging about the sexual prowess of the men she slept with. Peter was aware of this on multiple occasions due to their loud, extended lovemaking sessions that kept him awake. Over time, this became a significant turn-on for him, listening to Stacey moan in ecstasy through the thin walls and then seeing her in just her bra and underwear the next day. Since Alex was unavailable to provide hand jobs, Peter's masturbatory sessions became centered on these experiences.

Unbeknownst to Alex, their connection was strong and fulfilling. Peter was disheartened by the absence of sexual activity in their relationship - he occasionally received a handjob, but mostly found himself masturbating - yet Alex was definitely worth the wait. She had already had numerous boyfriends but none of them possessed the same level of sexual prowess he imagined himself having someday. She desired to ensure that Peter was "the one" before partaking in sexual activities with him.

Alex stood apart with her 5'4" height. Peter shared her pride in her long, dark hair, tanned skin, athletic frame, and generous derrière. Stacey boasted a spectacular physique, standing 3" taller than Peter with blonde locks, a voluptuous body, and seductive eyes.

During their senior year, Stacey and Alex shared a suite with two separate bedrooms, a living room, and a shared bathroom. This living arrangement gave them privacy in their own rooms while fostering camaraderie in the shared spaces.

Several weeks into their senior year, Stacey returned to the suite with her findings. Stacey needed volunteers for her Psychology of Sexuality research project. She had a daring idea: lock a man in a chastity cage for three months and analyze potential personality changes. The participant would be allowed prostate stimulation once a week, but the cage would remain locked the remainder of the time. He wouldn't be burdened with tasks but might be faced with light ridicule. His refusal could extend his stay in the cage.

"So, umm, I, well, Stacey, I'd like to assist, but... is this really necessary?"

"Well, think about it this way: we were typically apart over the summer, so there were no hand jobs for you. Isn't this more of the same, then?"

"Umm, I don't know that it's...I'm okay with this if Alex agrees."

"Alright, honey, I'll consider it and let you know," Alex stated.

The following day, they discussed Peter's potential involvement in Stacey's study. Alex explained the project to him while Stacey looked on. They required someone to accept locking in a chastity cage for three months. The prisoner would undergo weekly prostate stimulation, but would be continuously caged. There would be no requirement to partake in activities. However, refusal could lengthen the duration he was locked.

"Okay, well, umm, I... want to help. But is Alex okay with me doing this?" Peter nervously inquired.

"Oh, she's already agreed," Stacey calmly replied.

A few days later, Alex intimated that Peter could receive a blowjob from her if he were to assist with Stacey's study. Additionally, she offered him a lingerie photoshoot with both women, allowing him to keep the resulting images.

"Wow, that makes things more appealing." As Peter pondered his rewards, his penis began to stiffen inside his shorts. "I guess I'm in."

Stacey burst out in excitement, giving Peter a big hug as his head was enclosed in her cleavage. Alex also gave him a hug and whispered, "thank you."

"So, the next step is for you to measure for the device. Alex will be helping you with that."

They headed into Alex's room. When Peter took off his pants to reveal his erection, she giggled.

"I guess you need one more hand job before it goes in, huh?"

Peter nodded, and Alex started stroking his dick. She always held it with her thumb and forefinger, stroking the short shaft instead of using her whole hand. A few minutes later, he ejaculated, and she giggled at his pleasure. They snuggled for a moment before measuring his penis.

"That's... 2.5 inches long and 1.5 inches around! I'll let Stacey know so she can order the device."

Peter blushed at the thought of Stacey knowing his dimensions.

"Don't worry, no one cares about the flaccid size!" Alex comforted him, seemingly reading his thoughts.

Still, Peter thought he noticed a smirk on Stacey's face when Alex informed her of the measurements. Indeed, within a few days, it was revealed that the smallest device size was 3 inches or they could get a custom one. They all agreed on the latter option.

The device arrived a few days later, and Alex snapped it on. Then they sat down with Stacey to discuss the rules.

"Alex and I will each keep a key. You will only be unlocked in the event of a medical emergency. For the first month, it will be business as usual, and in the next two months we will try some experiments and document your response. Each two weeks will have a theme, and we won't share it with you beforehand. Nothing too extreme, but you should remember that this is a scientific study, and anything we do to you is for research purposes."

"And if you don't participate in these experiments, your time in the device will be increased by a week for each refusal."

"Will anyone else know about this?"

"Well, my research advisers will know, but they won't know about you. And apart from that, nobody will know unless they're essential to the experiment."

Stacey gave Peter a bright smile.

"How does the device feel?"

"It's not as bad as I thought... although we'll see."

"From what I've read, the first week will be the hardest, and then it'll feel like a natural part of you!"

One final instruction was given: "You'll need to release semen weekly for health purposes. I bought you a beaded anal toy. If you stimulate your prostate with that every week, it'll keep you free and clear! It'll also prevent you from getting blue balls!" Stacey giggled as Peter hesitantly accepted the toy.

The first month was uneventful as Stacey had promised. Sleeping became challenging during the first few nights, but soon, Peter became accustomed to the device. He did notice an increasing attraction towards the girls at school -- even average-looking girls seemed stunning, and the sexiest women on campus drove him insane.

Then the experiments began. It started on a Tuesday morning, when Stacey texted him:

"--Hey Carter, could you do me a favor? I need my car cleaned out. Can you have it done by dinner? Thank you! --"

Carter realized this wasn't random -- refusing to do the task would result in an additional week in the device. So, he promptly cleaned the car, wincing as he picked up used Magnum condoms from the backseat. She definitely has a lot of action back here, he thought.

The following day, Stacey asked him to clean a random dorm room's bathroom. He knocked, and Cristina answered the door. Carter didn't know Cristina well, or much about her, but she had one of the most gorgeous bodies on campus. He often masturbated to her Instagram pictures or fantasized about what she wore on specific days. When she opened the door in a sports bra and short shorts, he momentarily lost his breath.

"Hi Carter!" She greeted him happily. Peter was surprised she knew his name, but he supposed Stacey had mentioned it.

"Hi, um, I'm supposed to clean your, um, bathroom."

"Oh, right! Stacey mentioned you might be coming over. It's just down the hall!"

Carter tried to focus on the task but couldn't help but be captivated by his thoughts. [

How come she thinks I'm doing this? What did Stacey tell her? Will I have to repeat this?

Soon enough, he finished the task. He informed Cristina and she thanked him as he walked away.

The following day, he needed to wash Alex's clothes. While the job seemed mundane, he became aroused while folding her bikini bottoms and lacy underwear. If only I could see her wearing these... he thought.

Some days later, he was assigned to another room to clean. To his dismay, there was no one there. It was complete chaos. I hope this blow job is amazing...

Once finished, he sent Stacey the photos as she had requested, and she replied. "Thanks! Maurice will appreciate coming home to a tidy space after fucking me!"

Even though Stacey had always been active sexually, she would usually abstain from bringing guests into the room when Alex was present. However, that started to change around this period. Every few days, Alex would leave her room to clean her teeth and overhear Stacey's erotic moans with her male partners - always tall, athletic men, usually black athletes - experiencing her with what Alex envisioned was a notably substantial penis.

At first, Alex found these sounds unpleasant. But night after night of hearing them, combined with occasionally locking eyes with the fitness-buffed, attractive men in common areas, she started to be aroused.

One day, while they were watching TV with Carter in the living room, Alex brought up the topic.

"It seems like you enjoyed last night!"

"It was really fun!" Stacey said. "He was...important."

"How big was he?" Alex inquired with innocent curiosity, as Carter turned bright red from the sexual discussion in their presence.

"Oh, definitely big," Stacey continued, "but not so big it was uncomfortable or unwieldy. But boy was he well-hung - much bigger than anyone I've had before."

"Are you saying he was big enough for you?" Alex inquired.

"Not for every day, but it was definitely a pleasurable experience."

"9 inches!" Alex exclaimed.

"Yeah," Stacey confirmed matter-of-factly. "What, is Carter not well-endowed?" Stacey teased Carter.

"Well, no, but..." Carter said, feeling apprehensive.

"Don't worry, Carter," Alex replied. "It's normal for men not to be as large as athletes."

"Well, you know that saying, once you go black..." Stacey concluded.

"Wait - was he that big?" Alex asked.

"Mmhmm," Stacey responded, smirking at Carter. "Does Carter have a smaller than average penis?"

"Not unfairly small, but...is nine inches an average size?" Carter questioned.

"I guess it would seem big if you're used to Carter's moderately sized manhood."

"So Stacey," Alex began, "what's it like having sex with big guys like that?"

"Let's just say I definitely like it," she smiled.
