The Ballbusting Yandere

Note: I posted earlier about an effort to use stories on this sub to train an AI to write ballbusting stories. So far I've had some mixed results. The training process is taking a long time (days) to get just a tiny bit closer to being able to accurately predict/match the data in the training set. I have a feeling part of the problem may be the quality of the data. For instance many stories written by non-English speakers contain spelling and grammatical errors that might be confusing the machine.

The ideal long term solution would be a carefully proofread and edited collection of stories, and I'm reluctant to put that much work in unless I know I can ethically share the outcome of the project. So I wrote my own story from scratch (no AI assistance) to serve as the first story in a publicly available dataset. Once I have it uploaded somewhere I'll see if I can get permission from other authors to add their stories to the collection using my own story as an example of what the distributed content will look like.

P.S. I found an old post about matching story writers with editors, I'm not sure if that's still a thing but I would be happy to have this looked over by someone with more writing experience. I did my best to follow the editing tips in the comments of that old post, but English was always my worst subject 😆️. Anyways here's a story based on a concept that I don't recall seeing as I was glossing over all the existing stories on the sub.

CW: Castration (though not to MC)

# The Ballbusting Yandere

As Tom was getting a head start on his homework he couldn’t help but overhear some nearby students gossiping in hushed tones.

“Hey, did you hear about what happened to John?”

“Wait, don’t tell me the reason he’s absent today is…”

“That’s right, Jane the nut ripper got him.”

“Jesus, what did she do to him?”

“Apparently she tied him to a pole and kneed him in the nuts until he threw up. Then she skewered them with a bunch of needles before ripping them out with her bare hands!”

Jane the nut ripper. That was the name the local media gave to the unknown attacker that’s been assaulting and castrating male students at Bank Barnes high school. Her signature calling card was ripping off the guy’s testicles with her hands and keeping them as a trophy, hence the name. Tom felt his own nuts retreat a little further into his body at the thought of it.

“Did he see her face?”

“No, she was wearing that mask like always.”

“Did they find anything on Kelly yet?”

“Shhh! Dude, she might hear you!”

Everyone suspected Kelly. She was a tom boyish tough girl and the leader of a girls gang named ‘the Amazons’. It was pretty common for guys that mess with her to end up with bruised and swollen nut sacks. She’s even ruptured a few. Most of those guys were on the wrong side of the law themselves though, and the police had nothing concrete connecting her to Jane the nut ripper. Like most guys Tom simply gave her a wide berth, but a few hot heads decided to take justice into their own hands and came out with fewer balls than they went in with.

The gossip was cut short by the final bell and the daily PA warning:

“Attention all students, due to the recent rise in violent assaults we urge everyone to take appropriate precautions while walking to and from school. Please travel in groups and avoid isolated areas. Male students in particular are considered to be at high risk.”

Tom barely noticed the announcement at this point, having heard it so many times before. He gathered up his things and headed towards his locker with the other students.

On the way to his locker a bump from behind caused him to lose his balance and stumble forward, knocking over someone else on his way to the ground.

“Sorry, I—” Tom froze mid sentence as he got up enough to see Kelly glaring at him. Not only had he knocked her down, but when he put his hands out to break his fall they just happened to land on her large juicy tits. As her cheeks turned red he resumed in a panicked frenzy, “sorry, I didn’t mean to—”

*Thud!*

“OOOOOOOOOOH!” This time he was cut off by her knee slamming into his nut sack. He immediately moved his hands from her breasts to his groin as he crumpled into the fetal position in agony.

“Perv.” Kelly pushed Tom off of her and stood back up. She took a moment to collect her things and walked off, leaving him to nurse the pain in his gonads. She nailed them like a seasoned pro, and by the time he was able to stand and walk again he was alone in the hallway. He gathered his things and walked home by himself with a noticeable limp.

Tom took the same route home that he always did, but he couldn’t help feeling uneasy walking it alone. Especially after he just pissed off Kelly. He quickened his pace, hoping to get home faster. However as he made his way down a particularly secluded path, something hard collided with his head knocking him out cold.

Tom woke up to a throbbing pain in his balls. He groaned in pain and tried to cover them only to find that his arms and legs had been tied to the bed posts. He was also totally naked, and the girl squeezing his nuts was… Amy?!

“Wakey wakey, darling,” she said with a huge smile as she released Tom’s balls. She was a very petite and quiet girl. The sort that’s easy to overlook. She giggled as she hopped onto the bed wearing some *very* sexy red lingerie. “I’ve been waiting for this day for a long time.” She straddled his midsection, causing her modest breasts to jiggle in her tight outfit.

“Wait, what are you talking about? What’s going on?”

Amy giggled. “It’s time for us to be together my dear.” She smiled down at Tom and stroked the side of his cheek lovingly, her long black hair framing her cute round baby face.

“What are you saying? We aren’t a couple, I don’t even like you. You—” Tom was stunned into silence as he witnessed all semblance of emotion instantly vanish from Amy’s face, as if someone had flipped a switch. She repositioned herself between his wide open legs sending a wave of fear up his spine, then grabbed his balls with both hands and squeezed the life out of them.

“AAAAAAAAAAAAAAAAAAAAWWWWWW!” Tom had never felt so much pain in his entire life. It felt like both his nuts were going to burst into a giant pile of worthless goo any second now. He writhed in agony and pulled hard on his restraints, but they held firm. Just when he thought the pain couldn’t possibly get any worse, Amy twisted his nuts as far as they would go and pulled them away from his body until they were nearly at their ripping point.

Tears welled up in Tom’s eyes and his balls started to turn purple inside Amy’s two-handed death grip as she held them at the brink of castration. Her expression remained a cold heartless void as he writhed and screamed until his voice became hoarse.

Amy refused to let up for even a moment and ignored all of Tom’s desperate pleas and apologies with the same emotionless expression. She waited until he had quieted down enough to hear her, which didn’t happen until his voice started to give out from all the screaming.

“What did you say earlier? I didn’t hear you,” Amy said in an empty monotone voice.

“I-I said… I’ve… always liked… you,” Tom whimpered out in a high pitched voice.

“Awww, you’re so sweet.” Amy’s tone and expression immediately changed back to a cute and happy one as she finally released Tom’s testicles.

Tom gasped and groaned in relief and agony as his balls were allowed to untwist and fall back to their normal position. He made a mental note to never say anything that might upset Amy again.

Amy returned to her former position straddling Tom. “From now on, no one will ever separate us my love.” She slid her hips along his body, rubbing her pussy against him through her lingerie. He hadn’t even begun to recover from her devastating testicular assault, but she didn’t seem to care. She popped her nipples out of her lingerie and lowered her chest towards him, rubbing her naked breasts all over his face. “How are they? Do you like them?”

Not keen on having his balls ground into a paste Tom gave the only answer he could, “I love them, they’re very sexy.” Truth be told, this was Tom’s first time ever feeling naked breasts. It was remarkable that a creature with such soft and tender body parts could cause him so much pain through his nuts.

Amy giggled, pleased with Tom’s answer and slipped off her lingerie. “That’s a good boy,” she cooed and turned around, crawling towards his exposed groin. “This is your reward.” She scooped up his swollen nuts and started sliding her tongue all over them in long sweeping strokes.

“Ooooh! Oh fuck! Oh!” Tom began to moan and squirm in pleasure. The tenderness of his balls made the sensation feel ten times better as Amy started kissing and sucking on them too. Once again the restraints held him firmly in place as he squirmed, presenting his sensitive bits to her on a silver platter. As his dick rapidly inflated, she grabbed hold of it and buried it between her tits while she relentlessly targeted his balls with her mouth. His mind started to go blank with pleasure as she gave him a tit fuck while licking and sucking on his balls. His virgin dick didn’t last long and he came harder than he ever had in his life, blowing his load in between her breasts.

Amy giggled. “You came already? You’re so cute.” Even though Tom just came, she continued working on his nuts. He couldn’t help remarking on how she managed to make him feel both the worst pain of his life and the greatest pleasure all through those orbs between his legs.

“I love big meaty testicles,” Amy confessed as she kissed and licked Tom’s balls. “Ever since the first time I saw them I knew I needed to have them.” She slid her hips up and down, rubbing her clit along his body as she continued obsessing over his nuts. “That’s how I knew we were meant to be together, such big beautiful specimens.” She grabbed one in each hand and gave them each a firm squeeze.

“OOOOOOOOOOH!” Tom cried out in agony but Amy didn’t seem to care. She began kneading them with her fingers as her pussy left wet streaks along his body. He started writhing in agony again, but was shocked and confused when he suddenly felt her tight juicy pussy wrapped around his rock hard erection. He didn’t even realize he had gotten hard again, and feeling his dick inside a pussy for the first time was pure bliss.

Amy rode Tom reverse cowgirl, squeezing and kneading his balls the whole time. His mind went blank again, as the pleasure of his first proper fuck mixed with the pain in his balls. He couldn’t even decide if he loved this or hated it. When she finally came, she clamped down hard on his testicles causing him to cry out in pain. However the pain started to fade as the feeling of her pussy squeezing and contracting around his member quickly brought him over the edge as well.

Tom moaned in ecstasy as he blew his second load deep inside Amy. Then howled in agony as the pain in his balls was no longer masked by the pleasure in his cock. She let up the pressure but continued to hold his delicate orbs, rubbing them gently. The sudden change in sensations sent shivers through his body and he found himself trembling uncontrollably. She could do anything to him through those balls. Pain, pleasure, whatever she felt like, and he was completely powerless to stop her.

“A great pair like this deserves to be cared for specially.” Amy continued rubbing his balls. “It just wouldn’t feel right to give them the same treatment as the rest of my collection.”

Tom’s heart sank. “Collection?” he asked nervously.

Amy giggled. “You want to see it?” She slid off of Tom and skipped over to a large cupboard with a happy smile. “Look,” she says as she opens the doors to reveal, shelf after shelf of jars. Each one seemed to contain some sort of embalming fluid, along with a single pair of testicles.
