“FUUUUUUUCK!” She squealed, gasping as she adjusted to the new experience.
I continued to stimulate all of the sex centers I was playing with, and a minute later, she gasped again, spasming.
I took my queue and I positioned myself on the bench, lifting her legs and placing myself between them. Lizzy looked down at me worried, as I took my six inch cock and placed it at the opening of her tunnel.
Seeing the look of panic on her face, I assured her. “I will be gentle.” And I inserted the head as she nodded. I felt her hymen and drew it tight as I got close to two inches into her exceedingly tight pussy. I leaned down and kissed her, getting traction on the tiles with my feet and I pushed gently forward. Lizzy’s hymen strained for a second, then I felt it release, like the stem of a dandelion breaking in your fingers, and I carefully didn’t push in further.
Lizzy’s arms wrapped around me, and her legs squeezed my sides. I kept kissing her, and held her as she adjusted. After a few moments, her arms and legs relaxed, and I pulled away from her lips.
“Ready for more.” I asked.
Again, wordlessly, she nodded.
I resumed kissing her and pressed into her warm, wet depths. I rocked back and pushed in further, thrusting and making her moan into my mouth, as our tongues tangoed. As my dick opened her vaginal cavity, her lips and tongue became less and less responsive. When they fully stopped responding, I sat up, watching her remain stationary, her tits bouncing as I continued to thrust into her love tunnel. I began massaging her bouncing tits and continued to fuck my newest harem girl.
Lizzy moaned and was lost in the sensation as my cock filled her in ways she had never even known she would experience. I loved the happy haze on her face, but realized my climax was coming.
“Lizzy, I am going to cum soon. Are you on the pill? Do I need to pull out?” I asked her.
She shook her head, “On… the pill… please… inside…” She gasped.
I continued to press into her massaging, wet, tight pussy. I could feel her tightening as her orgasm built with mine. I couldn’t tell who was going to come first, but wanting it to be Lizzy, I began rubbing her clit with my thumb. The clamping down of her vagina pushed me over the edge and I thrust in deep and released my sperm into her womanhood.
“OH GOD!!!!!!!!!!!!!!!!” Lizzy yelled as my pulsing cock sprayed my white fluids into her.
“Congratulations!” Sarah told her, her tits swinging as she leaned down. “Was it as good as you hoped?”
Lizzy smiled, wiping happy tears from her cheeks.
“You can have it any time you want.” Sarah told her. “You can ask Tom to make you feel this way any time you want.”
Lizzy pulled me down in a hug, and whispered in my ear. “Thank you.” And I felt her vagina still massaging my cock in her depths.
“Now, Lizzy, we have a tradition of taking a picture of new girls the first time they have sex with Tom. We don’t show anyone outside of the harem. Is that okay?” Sarah asked.
Lizzy seemed unsure.
“If you don’t want to, you don’t have to.” I told her.
Lizzy tightened her grip on me. “No, I… I’ll do it.”
I kissed her, and pulled my cock from her womanhood. She groaned sadly as she felt the emptiness I had been filling.
I pulled out my phone and turned to Lizzy, “Pull your knees up by your breasts and smile.”
Lizzy, blushed, but complied, pulling her legs up and spreading the beautiful pussy I’d just fucked and her breasts slipped between her knees for a gorgeous picture of my freshly fucked, former virgin. There was a little blood, but I must have really enjoyed it, because she had a lot of sperm leaking from her baby tunnel.
I snapped the picture.
“Now, you never need to be embarrassed in front of me.” I told her, “You are beautiful, sexy and wonderful.”
Lizzy looked down, then said, “Thank you, but… can I clean up and dress… with just Tina and Sarah?”
I chuckled, and kissed her again. “Of course. Welcome to the harem.” I wiped my cock off with some toilet paper, flushed it, and pulled my clothes on. Giving one last satisfied glance at my newest harem girl, and walked out to the gym.
About five minutes later, Lizzy walked out of the locker room, fully clothed. She waved to me, then almost ran to the kitchen.
“That went about as well as could be hoped.” Sarah said, adjusting her skirt as she walked out of the locker room. “What were you wanting to talk to him about anyway, Tina?”
“Oh, right. That’s why you were here.” Tina laughed, she had changed into a t-shirt and jeans. “I think our experiment might be working.”
I took a second to realize what she was talking about. “You mean the cum drinking thing?”
Tina nodded. “So the difference between each cup size is an inch difference between band measurement and the bust measurement, and I have been one and a half inch different since I graduated high school. Almost exactly, an inch and a half. It has been consistent, because generally, your bust doesn’t keep growing. But after a month of swallowing your cum three times a day, I am now an inch and five eighths. I measured it 5 times this morning. That doesn’t seem like a lot, but that was just one month. If that continued, I could be two inches in another three months. Then I could be a C cup by summer. Now, I wouldn’t be surprised if it was less consistent, because rarely is something like that linear like that, but there may be something to this.”
“Shut up.” Sarah gasped, “Let me measure.”
Tina shrugged and tossed off her shirt and bra. Sarah grabbed the tap measure from Tina’s bag and measured.
“Holy…. She is right!” Sarah gasped, measuring again and taking a picture so she could compare to the picture we took when we started the experiment. “It is a small difference, but it is there.”
“Found a story about a doctor out in California who drinks a pint of sperm from her male friends each day. She was an A-cup when she started 10 years ago, and now she is a Double Z-cup.” Tina informed us, pulling her bra back on.
“What is a double Z-cup?” I asked.
“A twenty seven inch difference between band and bust.” Tina informed me, pulling up the story which had a picture. “At the writing of the article, she was still planning on getting them bigger, maybe a year or two. I can’t find any more information.”
The smiling blonde in the picture with the article had massive tits. They looked like basketballs held in her thin shirt. I’d say they were balloons, but there was enough flesh showing to prove they were flesh.
“Wow…” I muttered.
“Yeah, I had doubted all your talk about not wanting giant boobs, but seeing this, I can see why you might want them…. More reasonable.” Tina admitted.
The doctor’s boobs, if she was indeed a doctor, were stretched tight with several blue veins visible, and my immediate response was that they must be fake.
“Have you verified anything about the article?” I asked.
“Well, the same article is posted in half a dozen places.” Tina informed me, “I did a reverse image search and found one article from a European site claiming her tits were fake, but it was sketchier than any of the articles claiming they were real. Like I said, there are multiple places running the article about them being natural, but only one I could find saying they weren’t… and my bust size did go up a bit. She says in the article she was pretty flat chested in high school, and her boyfriend used the old ‘your boobs will grow’ to trick her into giving him blowjobs, but then it started working, and she started increasing her intake. So assuming that she went from A-cup to double Z-cup in ten years, that would be about a fifth of an inch every month, which is a little more than what I got. But even sucking you off three times a day, I think she was drinking more sperm than me. I imagine the amount most girls get from their occasional blowjob is mostly irrelevant. Even pornstars only intake bursts of sperm, as most don’t live their lives like a porn shoot. So like most things a rush of an input generally doesn’t result in long term results.”
“And the ethics of doing an official study of this nature makes it impossible to refute or verify without personal experimentation.” Sarah mused.
“So, if you are okay with it, I’m going to keep going, maybe until I have C-cup breasts, if it keeps working?” Tina asked. ”
“I mean, sure.” I told her.
“It is possible my breasts are swelling based on my current fertility cycle, so I will keep measuring. Sarah, would you be willing to keep helping me with this?” Tina turned to the other girl, pulling her shirt on.
“Of course, the chance we have to experiment this way is quite exciting, actually. I hope you don’t mind being the guinea pig?” Sarah assured Tina excitedly.
“Oh, you know, what girl hasn’t imagined herself with slightly larger breasts.” Tina laughed, “I bet Suki would eat a diet solely consisting of Tom’s sperm if it meant her tits grew a little.”
“Yeah, but we don’t want the girls all getting ideas.” Tina informed Sarah. “Tom’s body can’t make THAT much sperm and semen. And we’ll watch the long term effects before we have anyone going on the sperm diet.” Tina insisted. “I mean, I… I like how I’ve been feeling, but there is no proof that my increased energy, increased self-esteem and higher drive, both sex drive and other motivations, have come from drinking so much of Tom’s sperm. I don’t want to jump to conclusions.”
“Damn.” Sarah breathed, “If only we could do this study properly, and publish it, but the ethics of it would make us pariahs in the medical field immediately.”
Tina sighed reluctantly, “I know. I asked one of my professors if there had been any research about anything like this. She told me she didn’t know I had a boyfriend and he just wanted me to swallow. She said it was harmless to do so, but it wasn’t going to make me grow giant breasts. The assumption is that it is a trick boys use on their girlfriends. But I can’t help but wonder if this is one of those wives tales that got passed down and has some truth to it. Like how people were making tea with Willow bark long before the chemical was discovered in willow bark and made into Aspirin.”
Tina laughed and said, “Oh, damn. I am due for my second dose of sperm, but you just came for Lizzy. I’ll have to hunt you down in an hour.”
“Speaking of Lizzy…” Sarah murmured, she pulled out her phone and added the new girl to the text chain. “Welcome to the Harem, Lizzy.”
The other girls celebrated, and Lizzy tentatively said, “Thanks! I’m excited! Tom had sex with me earlier and I am a little sore.”
The other girls assured her that it was normal and it got easier after the first time.
“Speaking of new harem girls, you wanted to add Ruth’s other friends to the harem. Is there anything you need my help with for that?” I asked Sarah.
“Well, I don’t want to flood the harem.” Sarah mused, “But they all should be added before the end of the semester, and it is almost April now. Tamora will be the easiest, I think, to convince to join the harem after Lizzy. She might suspect something if Lizzy changes like how Suki did. I am not worried about her, Lizzy won’t say anything, probably to anyone. Tamora wouldn’t tell anyone unless she knew they already knew. Laura and Taylor I am trying to figure out on the order they should be invited. I think Ali should probably be one of the last ones because I don’t know how well she will keep it secret from her friends.”
“Okay, I will trust you to work with them.” I told her, “You may want to get consent from the rest of the harem sooner rather than later. I’d hate to have you prep one of the girls and have them get rejected.”
Sarah nodded, “I will. I gently encouraged them to get tested just before the lockdown started, so I know they are all clean. They are all virgins, or at least they talk enough like virgins that I believe it. They are way too frustrated to not be virgins, and if they weren’t virgins it would be frustrated in different ways.”
“So the only barriers to them joining the harem are themselves and the consent of the current harem girls.” Tina finished for her.
“Yep.” Sarah confirmed.
“You said Tamora might figure it out?” I pressed, “Like Ruth did?”
“Probably not exactly like Ruth, but yeah.” Sarah answered, thinking deeply.
“So what do I do if she confronts me?” I asked.
“If you have consent from the Harem, go ahead and take her somewhere private and explain everything to her. I’ll try to get you consent from that from the harem tonight.” Sarah directed, “If you want, you can always bring her to me. And I can explain everything, but I think Tamora would be on board even if the harem weren’t as great as it is.”
“Alright, well. I guess I’ll see you after dinner, Tina. And I will look forward to hearing from you later, Sarah.” I told them and left the gym.
Two hours later, Tina was busy sucking my cock when my phone vibrated with a text from Sarah. All of Ruth’s friends had consent to join the harem. Thinking of the four virgins, just down the hall that would likely join the harem, and I’d likely fuck them within two months, I dumped even more sperm than usual for Tina’s dose.
