I was 17 and finding ways to hit guys in the nuts was all I could think about. I'm really cute, if I do say so myself, skinny with short red hair, so guys were always approaching me at school and tempting me. The only problem was, I didn't want the whole school to know me as the girl who kicked guys in the balls. I had to find some way to do it without anyone finding out.

Right at the start of my senior year, I started volunteering after school as a counselor for the school, someone the other students could come talk to. Lucky me, that's where I met Amber. She started coming by every few days, and at first it was just small talk, but finally she told me that she's transgendered. Until that point I had no idea, she looked like a beautiful girl, a little on the tall side, with decent curves and beautiful wavy dirty blond hair. She said she had been on hormones for a while now and had just switched schools, because her secret got out at her old one. She was terrified of people finding out here, so I was the only one she could confide in.

That's when I realized she was perfect. If I worked this right, I could have all the fun I wanted and nobody would ever know. I slowly befriended her, which wasn't hard, and then invited her over to my house on a Saturday.

The next thing I did was call up two friends of mine, because I knew they would kill me if I did this without them. The first was a guy named Jet, a nice tall bisexual with spiked-up hair. We had dated for a little while, and I told him I wanted to kick a guy in the balls, hoping he'd be into it. He wouldn't let me, but he said he also wanted to try beating someone's nuts, so he became the first guy I could talk to about it.

The second was my little sister, Renee. She was 12 at the time. We got along about as well as two sisters normally did, but a few months ago she had asked me about guys' balls, and the more I told her the more excited she got. She was absolutely dying to hit someone between the legs. Plus I thought it would be hilarious to see a little 12-year-old dominating a 17-year-old tranny.

Finally the day came and we had all the supplies we needed. Amber came to the door and I invited her in and introduced her to the other two. She had no idea she was being introduced to the people who would make her life miserable. She was wearing a knee-length blue skirt, a white blouse, and long white socks. I told her I had something to tell her, and she turned to face me.

That's when I gave her a big grin and swung my foot right up between her legs. I could feel her parts through the thin fabric of her skirt and underwear, but they felt really funny. I realized she must have tucked everything back somehow, so her nuts were pressed right up against her body. Bad news for her, 'cause they got crushed right between my foot and her pelvic bone. At first she just stared at me in shock, then in what seemed like super-slow motion her face twisted up in pain, her hands went to her crotch, and she started doubling over. I grabbed her to keep her from falling on the floor, and Jet held a chloroform rag up to her face. Her eyes rolled back into her head and she went limp. Everything was going according to plan.

Before she woke up, we had to get her ready. The first step was to strip her down. Jet took off her blouse and bra, while I took off her skirt and panties. Renee got the shoes, and we decided it couldn't hurt to leave the socks on. Sure enough, her penis was taped back between her legs, and her balls were stuck up against her body. They were already getting kind of swollen and red, I guess I probably bruised them. I pulled off the tape, hoping it wouldn't hurt enough to wake her up, and then taped her little cock up against her stomach to keep it out of the way.

I guess it was a pretty average size, actually, but I couldn't tell when it was soft. Her balls were kinda big at this point. The rest of her body looked great, you really couldn't tell it was all thanks to pills. I was a little irritated to find no boob job scar on her C-cups. She had bigger tits than me, and I was a natural girl! Renee had a digital camera, and she was taking all kinds of pictures of the naked t-girl. Those would be important later.

The next step was putting her in position. We tied her feet together and her hands behind her back, put a gag in her mouth, and pulled her over to the coffee table. We tied her legs to the it so that she was stuck on her knees facing the table, since it was just the right height that her balls rested on the wood surface. That way they couldn't just flop around when we hit them. The final step was putting a rubber band around her ball sack, so they couldn't pull back in towards her body. She looked ridiculous like that, tied to the coffee table with her testicles sitting there waiting to be hit, and Renee took more pictures.

She wasn't even starting to wake up yet, so we splashed water in her face. She still looked groggy, so I gave her a nice hard slap to her left tit. That woke her up. She stared for a few moments, taking everything in, and I could see fear in her eyes.

"Sorry about all this, Amber," I said, trying to comfort her with a smile. "I don't hate you or anything, I just needed someone with balls to hit. Nothing personal. So we're gonna smack your nuts around, and then we'll let you go, no problem, okay? You'll heal just fine, and if you tell anybody, we put these pictures up all over school." Renee took another pic, and Amber glared at her. "So just sit back, relax, and it'll all be over soon."

That's when I punched her in the nuts, slamming them down onto the wood table. She groaned loudly, and she tried to go into the fetal position, but she couldn't. I grabbed her testes in one hand and rolled them around, feeling the spheres getting bigger. She was wincing so I asked her, "Does it hurt just touching them like this?" and she nodded. Guess she must be pretty bruised. I pinned one ball to the table with the palm of my hand, and slowly put more and more weight on it. I could feel it get a little bit flatter under my hand.

Wanting to try something different, I switched positions so my bare foot was on the table. I pushed it down onto her balls and she let out a painful moan. Guess my legs were a lot stronger than my arms. I felt them flatten a bit more.

"Aw man, what's it feel like?" Jet asked, and I tried to describe it. "Her nuts are warm and soft, kinds like hardboiled eggs or something, but not that soft. I can feel them get flatter under my foot." He begged me to let him go next, and I wanted to see what he'd do, so I backed off and watched.

He started out with his hands, just rolling her nuts around like I did, feeling them. He got one in the palm of his hand and squeezed it, digging his thumb into the flesh, and Amber's eyes started to tear up. Then he tugged on them, hard, trying to pull them as far away from her body as possible. His arms were a lot stronger than mine, and I could tell Amber was in agony.

Then he switched gears, like I did, changing to using a foot instead. Unfortunately for Amber, he was wearing hiking boots, and didn't feel like taking them off. His big leather boot came down on her nuts hard, and I'm sure the rough treads on the bottom hurt bad. He rolled her balls around under his boots, slowly pushing down harder, and she was sobbing and making choking noises. When he took his foot off, her balls were dark red and had marks dug into the skin from the pattern on the bottom of his shoes. As his big finish, he gripped her nuts in his hands and pulled up, HARD. It was like he was trying to pick her up by the balls. She let out a squeal and threw her head back. That had to really suck for her. He gave her testicles a good squeeze and then suddenly let them go, and they fell down and made a loud smacking sound against the table. I'm sure she felt that, 'cause she tried to jump from the sudden pain, but the ropes held her down.

It was little Renee's turn next. She looked really unsure and hesitant at first, 'cause she'd never touched guy parts before, so I encouraged her. "Just grab 'em and squeeze," I said, and she slowly took Amber's balls in her hands, feeling them. She gave them a light squeeze and Amber let out a squeak. At this point those nuts were real big and swollen, like big chicken eggs. Renee slowly got used to it, tugging the balls in different directions, squeezing them harder, that sort of thing, but she still didn't seem that into it. "Use your feet," I told her, and she climbed up onto the table.

My little sister really likes socks, so today she was wearing cute orange-and-purple striped foot socks. She pushed her right foot down on top of Amber's left nut, and slowly increased the pressure. Amber was already groaning in agony, but then Renee took it up a notch. She picked her left foot up and put it down on the other ball. She was actually standing on Amber's nuts! Amber was gasping and whining as Renee smiled down at her, really into it now. She even bounced up and down onto the balls of her feet, placing the entire weight of her body on those poor swollen balls. I could actually see them flattening under my sister's little feet! I made sure to get a few pictures of the 17-year-old tranny completely at the mercy of a skinny little 12-year-old. Finally I had to tell her to stop 'cause I was afraid Amber's nuts would get crushed completely. She slowly stepped down, grinning from ear to ear, and I knew she'd be a ballbuster for life.

I let Amber sit there gasping for air for a few minutes, since her nuts looked... All wrong. They were huge and somewhat flattened, and the sack was stretched out, plus they were a dark red-purple. After a while, though, I couldn't wait any longer, I had to get one last hit in. I grabbed her balls in my hands and pulled them up and away, and she whined in pain. I twisted them around as much as I could, then I held them in place with one hand. I raised the other and balled it into a big fist, then slammed it into her nuts. I punched as hard as I could, and she squealed in agony. I gave them a couple more good whacks, then finally dropped them down onto the wood table. They looked even worse than before.

"All right, no more," I said to everyone in the room. I held Amber up while the other two untied her, then we put her down on the couch. She curled up into a ball with both hands cradling her swollen, sagging nuts, and we decided not to bother her any more. "When you're ready, put on your clothes and go home," I told her. "Do anything else, and these pictures will be all over the place." She didn't answer, but I knew she understood. "Oh, by the way... Get well soon."
