"Partying with medical students is the best" David thought to himself, while taking another hit of the weed. He was not one of them, but he was a close enough friend to be let in and welcome. As expected, their expertise on drugs was unparalleled, the weed he smoke made him feel just the right mixture of relaxed and perceptive.

"Relaxed?" a petite, brown haired girl asked, sitting down close next to him.

"Oh yes, this shit is the best" he replied, with no filter over what he's saying.

"That is great news. Care to join us for a... private lesson?"

"Us?"

He's finally noticed the shorter, black haired girl to his left, mostly due to her hand making its way into the leg of his shorts.

"Us. I'm Caroline. This is Veronica. Let's... study together" the shorter girl said, while her hand weighted his balls, then measured his cock.

"I'm interested" he muttered, then stood up and followed the girls to a separate room.

Caroline unceremoniously pulled his pants down to reveal his cock.

"Woah, holy shit, he actually IS hung" Veronica exclaimed.

"Told you I can tell at a glance" her friend replied, with smugness in her voice, as she began to undress. "Let's impress our guest with our bodies in return, shall we?"

Soon enough, the two girls stood naked before him. Veronica, being slim but not malnourished, reminded him of a Barbie doll if it had more realistic proportions. Caroline, while short, was absolutely packed sexy features - a strong hourglass shape, pretty impressive tits, a very big ass compared to everything else, a pair of the best dick-sucking cherry lips he's ever seen. Despite her seemingly wide frame, she wasn't really fat, there was a surprising amount of muscle hidden underneath all the delicious jiggle. Both were his type, and his cock has stiffened to full in almost an instant.

"First lesson - sucking cock. Look and listen closely" Caroline spoke. "Men do like the whole soft and wet sensation of a blowjob, but nothing beats hitting the clit spot just right. It's right here, under the head of the penis" she said and then touched the spot with her tongue, causing David to spasm a little with pleasure.

"Why do you know so much about cocks?" David asked.

"Did you forget? We are med students. But more importantly, we really want to specialize in urology. We are passionate about dicks, and if we could, we would do what we're about to do to you to every man that we meet" said Caroline, then proceeded to fill her mouth with his cock, using the tongue to pleasure his sensitive spot. The feeling of her full, soft lips was also unforgettable on its own. She stopped close to his climax and asked: "want to finish him off?"

"Sure" replied Veronica, then continued after her friend. The impression that Caroline left on his cock was so good, that it really didn't matter how well Veronica was to do, he would cum soon anyway.

"Now that the premature ejaculation is gone, come here big boy" said Caroline, laying on her back, with her exposed ass and pussy at the edge of the bed. "I've seen the looks you gave my ass, I know you want it." He did. He began to fuck her with all the enthusiasm he had, his cock going in and out almost full length, her breasts fully grasped in his palms. "My oh my, it seems like me being short makes your massive monster cock hurt me a little. Don't worry though, I like it." She winked at him, then spread her legs a little more. Every consecutive thing to happen has made his experience more pleasurable and intense, despite him believing he's at absolute peak at the moment.

He finished, both panting loudly. His semen filled her up enough to leak out right away. She stood up, grasped his cock with one hand and balls with another, admiring them from up close. "Those little balls of fun can create quite a load, huh? Impressive, I don't remember getting creampied as much ever before." His dick twitched with excitement when she played with his balls and she's quickly taken notice. She then looked at her friend Veronica - "wanna get dicked? This one is really good."

"You bet!" Veronica laid down in Caroline's former place, spreading her legs to welcome David. They began to fuck. David was a bit worried that since he came twice already, this time it will take much longer and Veronica will end up feeling inadequate. As if in response, he felt Caroline's tiny hands on his back. They began a massage. The skin od his back was now being folded and stretched in relaxing ways. He felt her hands wandering lower and lower. Eventually, she cupped his balls in her hands. She has started playing around with his testicles by giving them a bit of a massage, moving them around a bit. Each thrust he did caused a little tug on his scrotum, quite rigidly held in a stationary position, and to his surprise he enjoyed this sensation almost as much as he enjoyed his cock and balls being praised and worshipped. Veronica was enjoying herself too, her moans becoming audible as her hands gripped the sheets in ecstasy.

"Oh wow, the feeling of being fully filled with cock, this is something else!"

"Yeah, that's something every girl needs to experience, I can't imagine a life without proper good cock from time to time" Caroline responded while rustling behind his back.

"Now that I know the feeling, I can't imagine it too!" Caroline chuckled as Veronica's words were choked out by the approaching climax. David felt a new cold touch from under his balls. Slippery. Rubbery? She's wearing gloves.

"What are you doing?"

"We were supposed to learn, remember? Since you are here, I might as well practice my prostate exams" she said, then he immediately felt her slender, slippery finger enter his ass. He felt awkward about it, after all, in his intuitive understanding the men should be putting things into women's holes, not the other way around. Well, he was way too invested in nearing another climax to stop it now, so he's let her penetrate deeper. She's rubbed him in some weird spot which has made him finish pretty much instantly, and then keep cumming way longer than he expected. She kept rubbing the spot, incapacitating him with an ongoing orgasm. After a good while of this going on and not stopping, she used her other hands to grasp his balls and squeeze them a little.

"Come on, cum it all out already." Her squeezing his balls has made him orgasm harder, as opposed to what she's expected - him retracting in pain.

"Well well well, for such a big-dicked manly man, you sure are a submissive bitch."

The words have filled his body with cold shivers of excitement, the hair of his whole body stood up in a massive goosebump.

"You're of the kinky kind, huh. How about a deal - I will let you fuck me one last time if you admit your balls belong to me from now on."

"My balls are your property..." he admitted, mumbling in shame. She was not having that.

"Loud and clear."

"My testicles now belong to you!"

She smiled a smile of a scheming woman, grabbed his balls tightly, and whispered face to face - "good boy".

She lied down on the sheets once again, her face and body perked up by the newfound satisfaction of enslaving a new man. "Now fuck me David, like your life depends on it. In the meantime, Veronica will practice an orchiectomy on your balls."

"Orc... What?"

"Orchiectomy. A reversible anti-conception procedure that disconnects your testicles from your body and leaves them infertile in your ballsack. Meaning, you have a literal time limit before you become unable to cum."

It sounded incredibly irresponsible and dangerous, which in the heat of the moment, would be the exact right thing to get him off. "Just give me a moment" said Veronica, then injected something behind his balls. "Now you won't feel the pain of it. Enjoy your last fuck!"

Aroused beyond any reasonable limit, he began to thrust into Caroline right away, her sadistic expression giving him a whole new kind of arousal he never knew existed. The entire time he felt the dull, painless touch of a scalpel in his scrotum, he felt his testicles being meddled with, and the feeling was making him surreally horny. As he started to approach a climax, he suddenly heard Veronica behind him:

"Aaand all done."

So quickly? He was very surprised. He looked back and saw Veronica disposing of her bloodstained gloves, and next to her a silver platter with two pink, meaty lumps.

And then the realization struck. He quickly pulled out his cock and looked down. His testicles were gone. The girls laughed at his misfortune.

"What have you done?!"

"Collected my property..."

"This is not what we agreed on!"

"This is exactly what an orchiectomy is you uneducated fuck. Not our fault you pack more dick than brain. We've castrated you for the good of everyone, dumbasses like you shouldn't be allowed to spread genes." She grabbed his deflating cock. "Pity this piece of meat is going to waste though... Oh well, we can salvage it with a penectomy later."

His confusion has finally turned to horror.

"You've castrated me!"

Caroline began to pleasure herself hearing this. "Yesss, say it louder! The only thing that turns me on more than men realizing they've lost their balls, is everyone around finding out as well. Don't get me wrong, they already know. Everyone in our university knows I'm really into castration, and everyone knew what was going to happen to you the moment you agreed to come with us. I bet some are even eavesdropping at this very moment. If this cheers you up, this was Veronica's first human castration, so that's one virginity you took today. Oh, what's with that face? Are you sad that you didn't finish in time before we took your manhood away forever? Don't worry, I can still make you cum." She stood up and started rummaging through a cabinet, her delightfully shaped ass jiggling just the way he liked it. He will never be able to enjoy a good fuck with a girl like that ever again. Eventually, she found what she was looking for - a strap-on belt. She's covered it nicely in a thick layer od lube, then said "on your knees and spread for me eunuch!"

He obeyed, and felt the rubbery device enter him right after. It was way less gentle that her fingers, but still managed to rub the spot just right. He felt another climax approaching, slowly but inevitably. "I've promised you that we'd fuck one last time once you surrender your balls to me, so here it is, hope it was worth it, ball-less loser. As you are about to cum one last time, I want you to truly think about how today you stopped being a man forever, how you permanently became a woman's property. I know that you are useless without your balls, so you have no choice but to surrender to me. When you come back tomorrow, be ready to serve my whims for no reward. And I know you will come back - pathetic guys like you always do."
