“George’s birthday is coming up,” Chelsea said to her sister, Abby. “We’ve only been together a few months, but I want to get him something nice.” They were having dinner in her apartment while George was away for the weekend. Chelsea was fairly tall for a woman, and quite muscular since she was a devoted gymgoer. She wasn’t a bodybuilder, though - she had visible abs most of the time, but was blessed genetically to also have large tits and a firm, round ass, along with thick, soft thighs. Her black hair went down to her shoulders. 

Abby looked at her and replied, a little bitterly, “Chels, why are you asking me? I don’t know a single goddamn thing about relationships, obviously.” Abby was a few years younger than her, a senior at the local college. She was a little shorter and had longer hair, but otherwise they looked quite similar, with caramel skin and exquisite curves. She was also a lesbian and kept jumping between failed romances, each time convinced she had found the one. 

Chelsea giggled. “Yeah, you’re lucky you’re graduating soon. You’ll probably run out of lesbians in the city by next year!” 

“Ugh, shut up!” Abby groaned, before smiling nostalgically. “You know, for Melissa’s birthday, I got this sexy lingerie and this cool toy that lets us –” 

“Abby, stop! I don’t want to hear you talk about this!” Chelsea yelped. “Let me just say, our sex life doesn’t need any help.” Her mind drifted to what she had done yesterday to see off her boyfriend. It was only for the weekend, but still; she had done her best to drain his balls, literally squeezing his third load of cum into her mouth. His squeaks of pain and moans of pleasure were like music to her ears. 

Abby grinned mischievously. “Are you still punching him in the balls?” She punched the air viciously and then mockingly grabbed her crotch, pretending to bend over in agony that she would never feel. 

Chelsea stuttered. “N- no, Abby, that’s not - it was just one time - I mean - ugh! Shut up!” 

Abby giggled triumphantly. She had hit George in the balls once, when he had mistaken her for her sister and hugged her from behind. Actually twice: first, a knee to dislodge him from her, and then a kick with her heavy boot as he crumpled to the floor. It had been very early on in Chelsea and George’s relationship, before Abby had properly met him, and she had walked in on them having sex afterwards. Abby hadn’t thought anything of it; after she stopped gagging at the sight of her sister riding him, she had figured Chelsea was just “nursing him back to health” or something. But a few weeks after that, she had come into Chelsea’s apartment unannounced, and seen them making out, naked, on the couch. Her older sister had been holding him close to her, one hand around his back to pull him into her body, and the other was lightly punching his balls as his very erect cock twitched and he groaned with every blow. The two sisters had a long conversation about boundaries after that, but Abby was allowed to keep her key to the apartment. 

“I can’t believe you two are into that,” Abby said, ignoring her sister. “Aren’t you worried they’ll like… pop, or something? Aren’t boys so fragile down there?” 

Chelsea blushed, even her light brown complexion unable to hide the redness in her face. “They *are* vulnerable, but that’s what makes it so hot. It’s like, I control his manhood, you know? I can make him feel whatever I want. The greatest pleasure or the worst agony.” She became less embarrassed and more passionate as she went on. “And he’s giving me control! That’s what turns me on even more: he loves me and is so into me that he just gives me that power over him. And honestly, the balls are so fascinating. I never really paid them much attention before, but they’re just these two delicate little organs that hang out in the open, and they mean so much to him, and I can totally control his world with a little force. I wouldn’t *break* them, they mean a lot to me too.” She shuddered at the thought of him feeling that much pain and losing something so important, all because of her. It was… to be honest, it was a little hot, but not something she would ever do. But maybe she would start threatening to do it… she would need to contemplate this more when she was alone with her vibrator that night. 

Abby thought about it for a moment. “When you talk about it like that, it almost makes me wish I was into men. *And*, if Melissa had balls, I could have grabbed them and *squeezed* when she cheated on me.” 

Chelsea thought about chiding her sister, but she understood the urge. “You’ll find someone, don’t worry. I had so many shitty relationships before I found George. You heard all about them!” 

Abby laughed. They had spent years consoling each other about their terrible love lives. “You should have discovered this kink years ago. It would have kept some of those guys in line.” She checked her phone for the time and said, “Anyway, I gotta go. It was good seeing you again, sis.” They hugged and said their goodbyes. It was still early in the night, and Chelsea showered before reading for a bit. 

It was a warm night, so she was only wearing boxers and a tank top. When she decided it was time to go to sleep, she put away her book and took out her vibrator. She hadn’t been using it as much, since she and George slept with each other nearly everyday for the past few months. The familiar buzz was almost nostalgic, bringing back memories of the beginning of their relationship. She didn’t bother with porn, just thinking back to the electric rush in her veins when George let her explore his balls after their first date, squeezing and kneading them. His winces and sharp intakes of breath contrasted so perfectly with how erect his cock was, the precum leaking from its tip matching her wetness. The vibrator’s intensity drove her to an orgasm quickly and she paused momentarily, her heavy breasts jiggling in the loose tank top as she gasped for air. 

Soon enough, she was recovered and back at it. This time, remembering the taste of his lips on hers, the way her tongue entered his mouth and his cock entered her pussy. One of her favorite things to do was have him fuck her doggystyle, but she would reach back and grab his balls. This was a difficult position but she was athletic enough to manage it, and grabbing them made him so pliable, fucking her in exactly the rhythm she dictated. It gave her a good sense of his stamina too: his balls would fight even harder to retract into his body just before he came, and she would pull them down, delaying his orgasm until she was satisfied. She remembered the feeling of his cock pulsing inside her, twitching as he fired his cum deep into her, and came a second time. 

She took another short break, playing with her hard nipples as her clit recovered. Chelsea loved how much George loved her tits. She loved wearing low cut tops and teasing him with her cleavage. Sometimes, she would keep count of how many times she caught him staring at her chest, and then punish him for it. She turned the vibrator on again. Her boobs were big enough that she couldn’t go around braless all the time, but she did so at home. She would bounce in place - or, honestly, just walk around - and they would jiggle and bounce, catching his eye. Then she could easily sack tap him. She would modulate her force depending on how playful she felt. Sometimes, it would be a light tap with her fingers, just reminding him that he belonged to her. Other times, it would be a closed fist punch, smashing his testicles and sending him to the ground. Chelsea came a third time at the thought of how easily she could take him down; even her lighter hits could, if they caught him off guard and hit him at the right angle. 

She was getting tired now, but couldn’t stop herself from continuing. She started using her hand to more gently rub her clit. Chelsea wasn’t always hitting his balls; they had loving, tender, sensual sex as well. Thoughts of him slowly licking at her pussy filled her mind; she loved to sink her hands into his hair and pull him deeper into her. She repaid the favor, of course. George could never last long when she took his cock into her mouth. She would suck on his balls, too, and then focus her tongue on his sensitive tip. She loved the sounds he made; his cries and whimpers of pain while holding his battered balls were hot, but his moans of pleasure as she sucked his soul out through his cock turned her on just as much. Chelsea came a fourth time. This was a slower, gentler orgasm that tired her out enough that she was about to go to sleep. 

She was a bit sweaty from her exertion and her tits shook from her heavy breathing. Before she pulled her hand out of her pants, she remembered the thought from earlier and immediately began to rub her clit again. God… she would *never* hurt him that badly, she knew, but it turned her on to think of it. Her fingers moved even faster than before on her sensitive pearl. Chelsea loved squeezing his balls the most. It was the most intimate and gave her the most control; a kick from her powerful, muscular legs would be more devastating, but she was honestly a little scared they would burst. Her thighs were big and not just for show. Besides, she preferred the ongoing suffering from a good squeeze. She could turn the pressure up or down at any time and George knew it. He would tense up as soon as she grabbed his balls, even when it was just to fondle them. Chelsea liked holding them a lot while doing mundane things, like cuddling up on the couch to watch TV. He liked giving his most vulnerable organs up to her and his cock would soon awaken. Sometimes this would lead to sex. Other times, she would just tease him, running her fingers up and down the sensitive underside of his cock or even stroking it a few times before returning to the balls that she owned. 

What if the next time she got her hands on his balls, she didn’t let go? Didn’t stop squeezing, even as he whimpered and pleaded for her to let go? Didn’t stop, even as they broke apart in the palms of her hands? Would they burst with a POP, she wondered, or would it be more of a squelch, or maybe silent, drowned out by his high pitched squeals of pain? Her fifth orgasm was violent, leaving her shuddering and gasping in her bed. 

After the long, bright glow of pleasure wore off, she was left a little disgusted with herself. George was hers to take care of. She would never hurt him that badly. Abby’s words came back to her then: he was so vulnerable, in a way that she could never truly understand, no matter how much time she spent exploring his male weakness. It hadn’t taken them long to realize they were both deeply in love. They had discussed having children within the first few dates, and they both wanted to start a family together. What if she accidentally kicked him too hard one day? Maybe they should get his sperm frozen, in case the worst happened. Chelsea spent the rest of the weekend looking into it and decided that this would be her birthday gift to him. If she broke his balls, there were ways for them to still have sex, though she would miss hurting them during their lovemaking. This would safeguard his ability to have kids, even without his testicles. A perfect gift.


*What did you think about this chapter? I enjoyed writing it a lot, but it is a little different than most stories. There's no actual ballbusting, just people talking about it and fantasizing. This was supposed to be the lead in to Chelsea and George actually going to the clinic, but it got out of control and I thought it would be better as as a standalone chapter.*
