Mia Helps Out Her Brother and Roommate (Mia, Riley, Julia)

CW: castration, bro/sis (nonsexual)

“Get me another beer?” Max asked dejectedly. 

“Sure,” Mia said and reached into the minifridge, “that test really got you down, huh?”

Max had come straight from his last final to his twin sister’s dorm room. After announcing that he thought he was going to fail all of his classes, he started depleting her beer supply.

“Yeah,” Max said as he ran his hand through his short blonde hair in a gesture that displayed well-defined biceps. “I could have done better on the exams, but I was really distracted. Leah broke up with me last night.”

“Finally?” Mia asked before she caught herself, “I mean, I knew she was thinking about it. Girls talk, ya know?”

“Yeah, she said we just weren’t working out,” Max replied glumly, “And now because I was thinking about her, I probably failed my finals. If I don’t get at least Cs Mom and Dad will stop paying for my apartment.”

Mia didn’t want to think about “his” apartment. Last August, when they both started their freshman year of college, it was *their* apartment. Their mom and dad agreed to pay the rent for a nice place close to campus. After two months, Mia realized that she needed more peace and quiet to study. The pre-med program she was in required an insane number of classes, and with Max’s late-night partying and all-day gaming, she was constantly distracted.

To her dismay, the solution her family decided was best was for Max to keep the apartment and her to move into the dorms, which meant she had to take out more student loans. It wasn’t all bad. She loved her new roommate, Riley. But the fact that Max got the whole apartment basically by being a shitty roommate still annoyed her.

“Well,” she said, pushing the thought from her mind, “I can’t help you with Mom and Dad, but I can help you get a girl if you want. Do you still have a crush on Riley?”

A blush spread over Max’s boyish face. “I don’t have a crush. I just. You know. Your roommate is hot.”

“Well,” Mia said, “She just broke up with Nate. I can put in a good word if you want.”

“Yeah!” Max perked up.

“Ok,” Mia said as a tight smile spread across her thin lips, “But you have to work with me, ok? Riley has high standards when it comes to guys. And, well, Leah told me some things about you that, uh, aren’t great.”

“Like what?” Max asked defensively.

“Well, for starters that you aren’t fixed,” Mia said seriously.

“What the fuck?” Max sputtered, “Fixed? What do you mean?”

Mia laughed, “Sorry, I didn’t mean to say it like that. I mean you haven’t had a vasectomy. There’s still a risk you’ll get a girl pregnant.”

“What the fuck are you talking about?” Max asked.

“Oh God, don’t you know anything?” Mia rolled her penetrating eyes, “Look, if you expect a girl to have sex with you, you need to get fixed. It’s too big a risk otherwise. This is why you’re still a virgin!”

“What? No! That’s not why,” Max stammered, “Leah never even asked about that.”

“Girls shouldn’t need to ask,” Mai said coldly, “We *always* look for the scars. If we don’t see any, we know you’re still a risk, and any serious girl, like Leah or Riley, won’t let you get past third base.”

“Are you serious? You expect me to have a major surgery and never have kids just to get with your roommate?” he asked in disbelief.

“It’s not a major surgery!” Mia laughed, “It’s a really minor one. Super easy! I learned how to do it this semester. You can just get it reversed if you want kids. It’s literally the least you can do to show a girl you care about her.”

“You’re kidding!” Max shook his head, “They really teach that surgery to freshmen pre-med students?”

“Not officially,” Mia grinned, “Every year, the senior girls in the program teach the freshmen girls. I told you, it’s really important to us girls. And a good thing to know if a guy is embarrassed to go to the doctor or just doesn’t want to spend the money. I did it for three of my guy friends this semester already!”

“You’re fucking kidding!” Max laughed.

“Not at all,” Mia said seriously, “Let me do you! You should get it done anyway, and I can casually mention to Riley that I fixed you. I know she already thinks you’re cute. It will be the perfect nudge for her!”

“That’s crazy,” Max said, but as his eyes met Mia’s she could tell that she already had him.

“Look, you want a chance with Riley, don’t you?” she asked reasonably, “You also don’t want to get anyone pregnant. And with me doing it, it won’t cost you anything. We can do it now! Just have another beer and let me get some things ready, ok?”

“I don’t know,” Max said softly as he traded his empty for a new beer. Mia subtly took out her phone and sent Riley a message full of smiley faces and scissor emojis.

\~\~

Within an hour, Mia had everything ready. A plastic tarp was spread on the floor. Towels were neatly arranged on her desk next to several sorts of pain killers. Her surgical kit was zipped up so that Max wouldn’t see the scalpels and freak out, and she placed it discreetly on the floor by her dresser, where she could easily access it without Max seeing exactly what she was doing.

Meanwhile, Max’s nervousness had increased the pace that he was going through beers, and he was beginning to look pale. Mia hoped he wouldn’t puke, but got a large bowl ready just in case.

“Ok!” Mia piped with enthusiasm, “Time to get you fixed!”

“Please don’t say it like that,” Max said unsteadily.

“Sorry, Bro!” Mia giggled, “You know what I mean! It will all be over super quick, and you’ll be so much better afterwards! Now take off your shorts and boxers and lie down here.”

Sheepishly, Max obeyed.

“Oh, God,” Mia said in disgust, “I forgot that Leah told me about that too! Don’t you ever shave down there?”

“No,” Max said embarrassed.

Mia rolled her eyes again, “Well, first, use a towel and rub this all over your cock and balls. It’s lidocaine cream. It will numb everything. I don’t want you getting excited by any of the stimulation. Then shave yourself.” She handed him an electric grooming razor from a dresser drawer.

Mortified, Max obeyed, and soon his crotch looked neater but also more vulnerable. Seeing the pale and totally defenseless expanse of flesh, Mia felt an exhilarating surge of power and couldn’t suppress a broad smile.

As she instructed him to sweep up and throw away the hair, it wasn’t lost on her that this was one of the only times he had actually listened to her when she had asked him to clean anything up. Maybe their relationship was already changing for the better!

By now, the skin of his sac and cock were numb. It was a distressing feeling, and he poked worriedly at himself.

She ordered him to lie on his back and pull his legs to his stomach, holding his knees with his hands. He did so shakily, as she grabbed a small vile and syringe from her desk.

“This is injectable lidocaine,” she said as she measured a dose, “It will numb your balls, just like the cream numbed your dick and sac.” She saw the fear in his eyes and said sweetly, “Aww, don’t worry! It will just be a quick little pain, I promise!”

She pricked his sac in several places with the syringe until she was satisfied it was fully numb. She desperately wanted to sterilize him, but didn’t want to hurt him. Not too badly, anyway.

She gripped his right ball firmly and took a deep breath. As she breathed in, she thought how few women ever have the pleasure of having a guy in such a vulnerable position. As she thrust the needle into his ball, his high pitched yelp of pain gave her a surprisingly powerful rush of joy.

Suppressing giggles, she tried to sound sympathetic as she said, “Awww, I’m sorry, there’s just no way to do it totally painlessly. Just one more, I promise it won’t be bad!”

More giggles welled up as she watched the trembling fear in his face while she prepared the second injection. She couldn’t resist giving his left nut an extra hard squeeze that made him whimper and squirm before she thrust the needle in. Because they were both now expecting it, both of their reactions were more intense. Max yelped loudly and began to cry, which fortunately covered Mia’s high-pitched squeal of pure delight as euphoria washed over her.

She recovered and put on her sympathetic voice: “That was the hard part! Now we just have to wait for your balls to go numb.”

“Mia,” he whimpered, “Please, I don’t think this is a good idea.”

“Aww,” Mia cooed softly, “You aren’t going to back out now, are you? I told you, the painful part is over. If you want this done later at a hospital, they’ll have to start all over. That’s two more needles in your balls! And if you don’t get it done sometime, no worthwhile girl is going to want to have sex with you, so you’ll be a virgin all through college.”

As she spoke, she had been tentatively squeezing his balls, gauging his reactions as the lidocaine took effect. She noted with satisfaction that although she was now squeezing them hard, he was barely reacting. She wondered with a giggle what he would feel like once the painkillers wore off.

Unable to help herself, she thought about him getting the apartment that was supposed to be for both of them and squeezed both of his nut hard in her fist. She felt them distend between her fingers. God, that was satisfying! she thought as exhaled.

Max was still whimpering but not saying anything, so she said seriously, “You have to hold totally still now, ok? Don’t even talk. One wrong move and I might accidentally castrate you!”

“Wait…!” he gasped, but she was already running the scalpel across his sac.

“Shh!” she hissed sharply, “What did I just tell you?”

Pushing her enjoyment to the back of her mind, Mia focused on making a small slit in his sac. She maneuvered her slender fingers precisely as she worked one ball and then the other out. She took a moment to appreciate how alien and totally helpless they looked outside of their protective sac.

Just then, the sudden sound of someone unlocking the door made both her and Max jump. Standing in the doorway with a bright smile on her face was Mia’s roommate, Riley.

Riley looked like she was ready for a big date. She had put her red hair up in an elaborate braid, with delicately curled strands flowing down to frame her face. She was wearing a loose camisole that accentuated her soft shoulders and pert breasts and a tight-fitting short black skirt above strappy kitten heels.

As she took in the scene, the smile on her face grew. “Oh my God! I’m so sorry to interrupt! Max, is that you?” she laughed, “I’m sorry! I know I was supposed to already be moved out for the summer, but wanted to go out one last time here. Oh my gosh! Mia, are you fixing your brother?”

“Yeah!” Mia chirped happily, “Can you believe he hasn’t been yet?”

“The important thing is he’s doing it now!” Riley said enthusiastically, strolling into the room and looking down at Max, “Whose the lucky girl you’re getting snipped for? I heard you and Leah broke up.”

“Yeah,” Mark managed to spit out, feeling like he might die of embarrassment. He frantically want to cover himself but was afraid of what would happen to his exposed balls if he moved.

“He’s doing it for whoever the next girl is,” Mia answered for Max, “Isn’t that thoughtful of him!”

Riley smiled warmly at Max, “It sure is! I didn’t know you were such good boyfriend material! Do you mind if I watch? I’ve always found this operation… exciting.”

Max was bright red and too embarrassed to even make eye contact, so Mia answered again, “You can do more than watch. I could really use your help! Max is kinda bad at keeping his legs still. I’m afraid I’m going to cut something I don’ want to! Would you sit on them?”

“Like this?” Riley asked as she planted her feet on either side of Matt and lower herself down so that she was sitting on the backs of his bent thighs, pressing them down.

“Perfect!” Mia smiled, “Just hold him like that and I’ll have him sterilized in no time!”

The position that Riley was in, with her knees locked outside of Max’s knees, left her own legs spread. Max saw immediately that she wasn’t wearing any panties. He tried (unsuccessfully) to pretend like he wasn’t looking at the soft, inviting folds of skin that were framed by close-trimmed pubic hair.

“Oops,” Riley laughed, “I guess I’m giving you a little show, aren’t I? Sorry! The other reason I came back was I accidently left all my underwear here when I moved out. But, under the circumstances, I guess it doesn’t really matter much.”

Max muttered an apology and shifted nervously, but Riley’s weight held him in place and her eyes locked onto his. “It’s ok,” she said soothingly, “I don’t mind. You know this operation really does excite me. And, it shows you are going to be a good boyfriend for someone. Maybe after you’re feeling better you can take me on a date. What do you think?”

Max nodded. “Thank you” was all he could think to say.

Meanwhile, while her brother was distracted, Mia was working quickly. She had told a small lie. She had never performed a vasectomy before, and isolating the vas deferens in the spermatic cord and then snipping only it wasn’t something she felt confident doing. Instead, she had planned all along to perform an epididymectomy, but didn’t want to risk scaring Max with the details.

The epididymis, the tight cluster of tubes at the back of each testicle where sperm is stored before it reaches the vas deferens, was super easy to identify, and it only took a matter of seconds for Mia to make the slices necessary to sever it from Max’s right ball.

The big difference between a vasectomy and an epididymectomy is that many vasectomies can be reversed (though not nearly as certainly and easily as Mia had led Max to believe). But once she finished with his other ball, there would be no way her brother was ever going to father children of his own.

The thought filled her with a mischievous happiness. She thought about the time their dad, without thinking about Mia’s feelings, had proudly proclaimed that Max was special because he as “going to carry on the family name.” As if she couldn’t give her kids whatever name she wanted and as if his family’s name was more important than their mom’s, which she had given up when she got married.

She smiled thinking about how horrified her dad would be if he could see her casually ending Max’s ability to pass on his genes. With a deep sense of satisfaction, she severed the epididymis from his left ball. That was it. If Max passed on the family name now, it certainly wasn’t going to be to his biological kids!

Glowing with pride, both at her surgical skill and at control she had just taken over her brother’s future, Mia finished cauterizing the wounds, gently slid his balls back into his sac, and stitched the incision shut.

“All done!” she announce happily and Riley clapped her hands in delight.

Riley kept Max pinned in the same humbling position while Mia put two pills in his mouth and told him to swallow. With all the beer that Max had drunk and the physical and mental stress of what he had just been through, the tranquilizers kicked in quickly. As he stared dreamily at Riley’s wet pussy, he quickly drifted out of consciousness.

\~\~

When Max came to, sunlight was streaming on his face. His first thought was that he had drunk way too much last night. He had this weird dream that he let his sister… OH FUCK! He sat bolt upright and his hands shot to his aching balls. Fearfully, he ran his finger over the fresh row of stitches in his ball sac.

“Oh shit!,” he said to himself, “Did I really let Mia fuck with my balls?”

He heard a giggle to his left and jerked around to see Riley lounging in the bed on the other side of the room. She was wearing boy shorts and a pink crop top. Her vibrant red hair was down now, flowing over her shoulders in messy curls, and she had a wild, mischievous look in her eyes.

“She didn’t fuck with them,” Riley laughed, “She just sterilized you, that’s all. Guys are so dramatic. I’m surprised Leah never got you taken care of before. I guess you weren’t having sex?”

“No,” he admitted quietly, bowing to a strange power that he now felt Riley had over him.

She swung her legs over the side of the bed and planted them wide in a stance that filled Max’s mind with the memory of his view up her skirt the night before. The image filled him with a strange mixture of arousal and humiliation.

“So, are you still a virgin?” she asked directly.

“Yeah,” he muttered, looking down. He only then realized that he was in Mia’s bed. “Where’s Mia?” he asked.

“Oh, she took your keys and went back to your guys’s apartment. She said you won’t mind if she takes it for the summer. After your little surgery, you’re going to need to rest and then do some things she isn’t comfortable being around for. Because she already had permission to stay in the dorm through summer, I agreed to move back in and help you with those things here.”

“Wait,” Mark said in bewilderment, “help me with what things?”

“Well, first recover,” Riley smiled, “Speaking of which, pull down that sheet and let me see how they look. Oh, come on, don’t be shy! I’ve already seen them out of your bag! You’re going to have to get used to me inspecting them if you want me to help you recover.”

Slowly he lowered the sheet. His scrotum was bruised and his balls swollen. Seeing Riley, though, made his cock rise weakly, despite the pain.

“We should get some ice on there!” Riley said as she retrieved an icepack from the minifridge and sat beside Max on the bed. Instead of just placing the icepack on his balls, where it was needed, she pressed it onto his cock and got a gratifying thrill of power as she felt it soften and shrivel. She pressed down firmly, slightly compressing his balls beneath the ice in an effective display of her dominance.

“Here’s what we are going to do,” she said coolly as he squirmed, “For two weeks, I’m going to make sure you heal. That means absolutely no cuming. Do you understand?”

“Yes,” he said meekly.

“Normally, a doctor would prescribe something to keep you soft, so you aren’t tempted to cause any damage while you heal,” she explained, “Instead, I’m going to put this on you.”

She produced a small, pink chastity cage from under the bed. “I’m sorry about the color,” she giggled, “It was all the local store had in stock on short notice. Oh, also, don’t worry about paying us back. Mia took your credit cards along with your keys and ordered it online.”

“But…” Max began before he was cut off by the sharp pain of Riley pressing hard on the icepack.

“Shh,” she ordered, “I don’t want you to talk while you’re recovering. Just listen. I’m going to lock you up now for your own health. I’ll wear the key on my necklace, so you can always see that it’s safe, but I’m not unlocking you until you’ve healed up for three weeks.”

Max didn’t resist as Riley secured the cage. He was confused by the situation and his feelings. Was she flirting with him? Looking at him as her next boyfriend? If so, had he already given her the power in the relationship?

“Aww, that looks so cute!” she exclaimed as she leaned her back against the bed’s footboard and smiled at the way the cage pushed down his flaccid cock and pushed forward his swollen ball sac, “Let’s get to know each other! Here, massage my feet while we talk!”

She swung her feet fully onto the bed and rested them between Max’s legs. Her pale toes, adorned with light pink nail polish, brushed lightly against his nuts, causing him to reflexively lift her foot into his hand. For the next hour, he massaged one foot and then the other, blushing and shifting nervously as she regularly grazed his balls and caged cock with the idle stretches of the foot he wasn’t massaging.

She asked him some questions but mostly talked about herself. Max learned that she had recently broken up with Nate after discovering that he had been having sex with her friend, Morgan.

“I don’t know if I should tell you this, but last night, when Mia said she was ‘fixing’ you, I was really excited because I thought she meant *fixing* fixing. Do you know what I mean?” she asked, jabbing her foot into his bare balls hard enough to make him whimper.

She stared at him until he finally said softly, “Cutting off my…” but he couldn’t bring himself to finish the sentence.

“On the farm, we call it castration,” she laughed, “It’s good for male animals. It doesn’t just make you better behaved, it makes you happier. Did you know that Nate felt so guilty after he cheated on me that he asked your sister to cut off his balls? It was too little to late, but the idea of a castrated boyfriend really turned me on! So, when I thought that Mia was really fixing you, I thought, oh my God, that is so hot! I think you saw how wet that made me, didn’t you?”

Max gazed in embarrassed silence as he watched a flush of excitement spread over Riley’s face. He looked at her smooth, slender legs and remember how wet and inviting her pussy had looked last night as she had pinned him to the ground. He would give anything to be inside her. But if he gave up his balls, would he even be able to do that?

His cock began to harden and pressed painfully against the cage.

“Oops!” Riley laughed as she playfully rubbed the cage in a circular motion with her foot, “It looks like someone is getting excited! Don’t worry, I promise it will get easier. After a few days in the cage, your little dick will learn to stop trying to get out. It’s cute that you are so excited just talking to me though! I did say that you could take me on a date, didn’t I? Although I’m kinda disappointed that you aren’t *totally* fixed, you can still take me out one time after you recover, sound good?”

“Yes,” Max said humbly glancing from the outline of Riley’s nipples against her top to the small key hanging from her neck.

\~\~

Over the next days, Max passed the time in the small dorm room in different ways. When Riley was there, he talked to her, or rather, mostly listened while she told him about herself. When she was gone, he sometimes used the small area of open floor to do push-ups or sit-ups, sometimes watched TV, but mostly wished that she would return.

He was embarrassed to always be naked, but Riley said she didn’t know what happened to his clothes. Finally, she agreed to drive to his apartment and get some clothes and his PlayStation.

When she returned, she had a duffle bag crammed with all the clothes from his closet. “Here you go,” she said tossing the bag on his bed, “Mia said she’s using the PlayStation, so I didn’t take it. Look at this though!” She spun around to show off a loose summer dress. “Mia got me this with your credit card as a thank you for taking care of you,” she explained, “Isn’t that nice?”

“My credit card?” he exclaimed.

“Oh, don’t worry,” Riley said with a wave of her hand, “It was just a little purchase. And she saved you so much money by neutering you herself, it’s really the least you owe us! Don’t be grumpy about it or I won’t show you the bra and panties she got me!”

“Sorry,” he said humbly trying to will the tightness in his cage to lessen. Riley was right, he was getting hard less often, but it was still uncomfortable when he did.

“Before you get dressed,” she instructed, “You need to shower.”

“But,” he said uncertainly, “the only shower on this floor is for the girls who live here. I’m not even supposed to be staying here.”

“Don’t worry. I talked to the dorm RA, Julia, and explained your, uh, situation,” she smiled and nodded at his caged cock, “She said she just has to do an inspection, but then you can use the shower.”

“An inspection?” Max asked, but was interrupted by a knock on the door.

Before Max could do anything other than cover himself with his hands, Riley had opened the door and welcomed in Julia. Max recognized her immediately from the girls’ soccer team. He and his friends sometimes went to games just to admire her huge boobs. He blushed looking at her curvy figure in soccer shorts and a snug tee-shirt.

“Hi!” she smiled to Riley, barely glancing at Max, “So, he’s locked up safe and sound?”

“Yep,” Riley responded happily, “He’s recovering from a DIY vasectomy Mia gave him, so no cuming for another two weeks.”

“Nice!” Julia smiled, “In that case, I just need to check that the cage is secure.”

She stepped so close to Max that her ample chest brushed against him as she felt the cage, turning and pulling it slightly to make sure that it was inescapable. Then, she gripped both of his balls tightly in her fist and yanked them hard twice. How the fuck was that testing the cage? he thought as he doubled over and tears welled up in his eyes.

“Looks good!” Julia exclaimed cheerfully, “Is that the key around your neck?”

Riley nodded.

“I’m going to need you to give that to me as well as the spare,” Julia said matter-of-factly, “I’ll keep them in the safe in my room. If you need to unlock him for any reason, just get me. I’m here most nights, and you can always text me and I’ll respond within 24 hours. Whenever he needs a shower, let me know and I’ll supervise.”

Max feebly objected as Riley handed Julia the keys. Then Julia grabbed Matt’s balls painfully tightly and pulled him into the hallway. The few girls who were on the floor for the summer all seemed to have their doors open and smiled or giggled as they watched Julia drag Max down the hallway to the showers. One girl he recognized as his ex-girlfriend Leah’s best friend and prayed that she didn’t recognize him.

After confirming that the shower room was empty, Julia led Max in and watched sternly as he showered. When he finished, she threw him a towel to dry off, but didn’t allow him to cover himself as she pulled him back down the hallway, past all of the giggling and waving girls again, to Riley and Mia’s room.

The embarrassment convinced him that he should just leave. He had clothes now, although no cell phone and no keys or wallet. Surely, though, he could find someone to give him a ride back to his apartment and then get all his stuff back from Mia.

But, he changed his mind immediately when Riley opened the door wearing only a lacy bra and panty set. Through the lace, he could make out her small, firm nipples and the soft folds of her pussy.

“Now that Julia has the keys,” she said with a broad smile, “I’m comfortable wearing things like this, knowing you aren’t going to beg me to unlock you. I figured I would give you a something nice to look at while you paint my toe nails.”

Max was filled with genuine gratitude as he entered the room and set to his task.

\~\~

At the end of the three weeks, Riley announced excitedly, “It’s a big day today! You should be all healed up and ready to cum! Julia will be here with the key any minute.”

“Oh my God!” Max almost wept, “I can’t wait to be inside you!”

“What?!” Riley laughed, “No. No. No. No. What the fuck makes you think you’ll ever get to be inside of me?”

“You don’t want…” Max stammered, “Why are you doing this if you don’t want me to…?”

“I’m doing this,” she said firmly, “as a favor to your sister and any girl you date after this. I promised you one date, just one, after we are all done. And there are no promises that anything is going to happen on that date. Do you understand?”

“Yes,” he said embarrassed, “I’m sorry.”

 “One thing is certain, though,” she said grabbing him firmly by the balls, “you aren’t going to put your little dick inside anyone until there is zero risk of pregnancy. Mia says that you could still have leftover sperm in there for up to two months. So, my job for the rest of the summer is to make sure that you don’t get close to any pussy until your sperm count is zero. After that, you can do whatever you want. Do you understand?”

“Yes,” he said defeatedly.

Just then, Julia arrived with the key. She watched with interest as Riley unlocked Max and ordered him to sit on the floor.

“It will take a while for you dick to remember how to get hard,” she said in an almost sympathetic tone, “So I’m going to be nice and touch you a little to help you out. But only with my feet. While I do, you can look up at me and fantasize about whatever you want.”

She trapped his cock, which hurt from being caged, under her foot and began to slowly grind. From this angle, her legs seemed incredibly long, and he felt insignificant under her gaze. He wondered, had Mia really cut off Riley’s ex-boyfriend’s balls? Did Riley get off on that? She looked like she wanted to grind his own manhood out of existence. An image of her wet pussy sprung into his mind, and suddenly, cum spilled out of his semi-hard dick in spasms.

“Oww!” he yelped as unexpected pain filled his balls, “Oh shit. It hurt when I… when I…. Oh fuck, that hurt!”

He looked like he might vomit and fell forward clutching his balls.

“Huh, that’s strange,” Riley said with interest, “Mia said that you might have some pain, but I didn’t think it would be so dramatic!”

“It feels like I got kicked in the balls,” he moaned.

“Well, unless you want to get kicked in the balls for real, you need to lick the mess you made off of my foot,” Riley said with a grin as she rubbed her cum-coated toes against his mouth.

“What?” he began to protest but couldn’t say more as Riley pressed her toes into his mouth. Still cradling his sore balls, he began to dutifully clean her foot with his tongue. Riley sighed contentedly as Julia looked on and laughed.

“Good job!” Riley said when she was satisfied her foot was clean, “Now, clean up the rest of the mess that you made with these washcloths. But save one to jerk off into. We still have to get you drained.”

“But it hurt so bad,” Max objected.

“It felt like getting kicked in the balls?” Riley asked and Max nodded, “But, did it feel like getting kicked in the balls by a soccer player?”

When Max looked confused, Julia jumped in, “It’s my job as an RA to make sure that no guys are causing problems. And I know exactly how to deal with guys who are.” She stepped forward quickly. Matt dropped the washcloth and lurched to protect his balls, but too late. Julia’s muscular leg sent her tennis shoe rocketing directly into both of his nuts, and for a moment the pain made the world around him go dark.

“Do you know how hard you have to kick a guy to break his balls?” Julia asked, “I do. So does my ex-boyfriend Zack. You should ask him about it sometime. He doesn’t like to talk about it, though, or about why he hasn’t had another girlfriend since we broke up.”

Max remembered hearing the rumors about Zack, that he had dropped out after he had some kind of accident and had to have his balls cut off. He didn’t believe them at the time, but looking up at Julia’s wickedly smiling face above the shelf of her chest, he wondered. He never wanted to feel the pain of a kick like that again and decided that anything would be better than risking it.

He jerked off into the washcloth as he was ordered. First Riley instructed him him to look at her feet while he did, then at Julia’s legs, then Riley slid off her cut-off shorts and silky panties and told him to focus on her wet, neatly trimmed pussy. Although this excited Max, his cock was sore from being caged for two weeks, and his balls exploded with pain each time he came. By the time he forced out the last, quivering orgasm, he felt even more frustrated than when he had started.

“Good boy!” Riley said pleased, “Clean yourself up. Then, I’ll lock you up again so you can thoroughly clean the room and do the laundry. We’ll unlock you and drain you like this once every week until school starts. By that time you should pose zero pregnancy risk. Then you can take me out, like I promised!”

For the first time, Max realized what a long summer he was in for, but the possibility that he might get to fuck Riley at the end of it gave him hope.

\~\~

By the time the summer was drawing to a close, Max was very different than he had been at the start. It wasn’t just that he was now able to accept the agonizing pain in his balls whenever he came (Riley said that Mia promised to research the issue, but Max had given up hope that she would find with a solution).

The bigger change was that it now felt normal, instinctive even, for him to do whatever Riley told him to. He never hesitated when she told him to clean the room, or make her bed, or do her laundry, or paint her toe nails, or spread his legs so that she could give him a quick kick in the balls as punishment for doing any of these things insufficiently.

Even the embarrassment of Julia regularly dragging him down the hallway by his balls to shower had dulled. In late July, his ex-girlfriend Leah started regularly showing up on shower days to watch from her friend’s room as he was paraded by her open door. Both of them smiled, giggle, and blew kisses as he passed. Although this humiliated him, he felt strangely resigned to the fact that he was now powerless to resist Riley, Julia, or any other powerful girl.

One day in late August when Julia returned him from the shower to the dorm room, he found Mia there, talking animatedly to Riley. Max felt awkward at first. By now he was used to Riley, Julia and the other girls on the floor seeing him in nothing but the small pink chastity cage, but it was the first time Mia had seen him like this. He noticed a slight smirk as she glanced at it and felt wounded. Although they were twins, he’d always assumed that Mia looked up to him as her brother. Now he didn’t see any of that imagined respect in her eyes.

She did, however, look happier than he had ever seen her. She was wearing a loose floral blouse that looked both professional and girlish at the same time and a short skirt that accentuated her long legs. Riley, Max noted, was wearing the same kitten heels, skirt and camisole that she was wearing when she accidently walked in on them three months ago. She had even styled her hair the same. The memory of that night made him feel even more humble than usual.

“Hey, Bro!” Mia greeted him cheerfully, “I’ve got good news. The test of the sample Riley collected last week came back. We did it! You’re sterile!”

Although the news wasn’t unexpected, it still gave Max a twinge of sadness that not even the hope of finally being able to enter Riley couldn’t overshadow.

“But I’ve also got some other things to talk to you about,” Mia continued in a more serious tone, “First, you’re going to have to start working again soon. I used your bank account to pay for the sperm test, but after paying off your credit card bills each month, your account is getting really low. I could only afford to buy Riley one outfit this week for taking such good care of you.”

Max slowly processed this. He hadn’t realized that in addition to claiming the apartment, Mia had effectively taken over all of his finances. The worry was quickly pushed out of his mind, though, by the next thing Mia said: “Second, one of the guy-friends I fixed like I fixed you told me that he tried to get it reversed, but couldn’t because I made the cut so big. I talked to one of the older pre-med girls, and I guess I’ve been doing the ‘irreversible’ style.”

“What?” Max gasped, “I can’t have kids?”

“That was kinda the point of the surgery,” Mia laughed, “Reversal was never a guarantee. This just means it’s definitely permanent. Trust me, though, this is so much better for you and any girls you date.”

“But, I want kids,” Max stammered in disbelief.

“It not your decision anymore,” Riley said coolly, and her voice instinctively silenced Max’s complaints.

“Mia and I have been talking,” she continued, “And we both agree that you should be fully castrated. You’re already sterile. It will stop the pain when you cum. And, most importantly, I want a long-term relationship with you. But only if we get rid of those balls now." 

“Now?” Max asked, pleadingly.

“Well,” Riley smiled, when we get back from our date, “I promised, so I’m going to let you take me out to a nice dinner. Mia already gave me your credit card to pay with. Then, we can come back here and I’ll let you do something you’ve always fantasized about before Mia castrates you. Now get dressed.”

Over an elegant dinner, Riley explained to him what their future relationship would be like. He would stay in the dorm as her pet eunuch. Julia would let him stay in the dorm as long as she was fully in control of rationing any testosterone he was prescribed and added a bit of estrogen to make sure he remained docile and impotent. Max would pay Mia back for the room by working. Mia would manage the money deposited in Max’s account to make sure that she and Riley were fairly compensated.

“It will be a lot like now,” she concluded, “but the big difference is that I’ll let you make me cum. You want that, don’t you?” He had to admit that he did.

When they returned to the dorm, the room looked exactly as it did on the night of the first surgery. Mia was seated at the desk glowing with excitement. “Are you ready?” she asked.

“Yes,” Riley responded at the same time that Max said “No.”

“What?” Riley asked Max annoyed.

“You said I could do something I fantasized about,” Max pleaded, “Can’t I take the cage off and fuck you?”

Riley laughed, “As long as you have balls, that cage is staying on. I don’t even have the key, and Julia is gone for the weekend. But I did promise. Haven’t you fantasized about making me cum?”

“Yes,” me answered desperately.

“Then take off your clothes and lie down on the plastic sheet,” she ordered and he obeyed. She planted her feet on either side of his head, and he saw that she wasn’t wearing any panties. She hiked up her skirt and slowly lowered herself onto his mouth.

“Lick,” she commanded.

He tried to say “yes,” but she pressed herself more firmly on his mouth and said, “Don’t talk, just obey. Pull your legs up like before.”

He did so, and she locked her arms behind his knees, trapping them firmly in place. “Ok, Mia, you can start working now,” she said.

At first, he struggled and tried to object, but Riley hushed him and told him to focus on making her cum. He did, gently licking and kissing while trying not to think about what Mia was doing between his legs.

He felt the stab of the lidocaine injections in one ball and then the other. The lurch of his body gave Riley her first orgasm, and she ordered him to slow down while she built to her next one.

It took Mia very little time to expose Max’s balls, but she paused to savor the significance of what she was about to do. She and Max were twins, but for all of their lives he slacked off while she worked constantly for a fraction of the praise and reward their parents, friends, and society in general seemed to think he was naturally entitled to. All because he was born with these silly chunks of flesh between his legs.

Well, that was about to change. She clamped each of the cords to limit the bleeding. She firmly gripped the right ball and pulled as she cut it free. Without putting the severed ball down, she closed the other one in her palm so that she was holding both of Max’s nuts as she cut the second one free. She look down with immense satisfaction and imagined how nice these little trophies would look prominently displayed in *her* apartment.

At that moment, Riley looked over her shoulder. The sight of the useless orbs in Mia’s hand set off a cascade of quivering orgasms.

Mia had been skeptical when Riley said she bet they could take Max’s balls without too much trouble, but she was right! A year ago, Mia probably wouldn’t even have admitted to herself how much she wanted to neuter her brother, but she now felt exhilarated and deeply fulfilled knowing that she had turned him into a ball-less pet for her best friend.
