The first time Jenny kicked me in the nuts was at a pool party. She's a tall busty blonde, and she looked amazing in her red triangle-top bikini. I wanted to get her attention, so I stole her phone. She chased me to get it back, her boobs bouncing wildly in her top, looking like they were trying to escape (which I loved to see). She wound up cornering me over in a grassy corner of the yard, so I held the phone up over my head. She tried jumping up to grab it a couple of times, but without success (although with more bouncing boobies, which I greatly enjoyed). Then she got an evil look in her eye and she delivered a hard knee right to my crotch. With nothing to protect me but my thin swimsuit, I went down in a heap. She leaned over me and grabbed her phone away. She sort of gave me a smirk and then strutted away. I stayed down longer than I needed to, to hide the big erection I got afterwards.
A couple of hours later, as the pool party was wrapping up, she and I wound up in the living room both waiting for a bathroom or bedroom to be free to change in. "Sorry," she said. "That was probably taking it too far. I don't usually knee a guy in the nuts unless they've done something to really deserve it, like grabbing my tits."
"Like this?" I asked with a smile as I suddenly grabbed one of her big soft breasts in each hand, squeezing them.
"Exactly," she said, smiling back. And then quickly, she rotated forward, swinging her knee hard and fast right into my balls. The impact was so forceful that it took my breath away and my legs turned to jelly. I was crumpled in a heap on the floor again before I knew it. A bathroom door opened and she stepped over me to go change.
I didn't see her again that day, but over the next few months, that became our thing: whenever the two of us were alone, I would grab her tits and she would give me a really hard knee to the nuts. They were forceful knees, her aim was spot on, and I'm not really a balls-of-steel type, so I would collapse every time. And usually, I'd wind up jerking myself silly remembering it for the next few days afterward.
I started trying to engineer times when we'd be alone, and she seemed to go along with this happily. There was even a time or two when I thought she might have arranged for an opportunity. In total, we wound up doing that about a dozen times over the course of a year.
It all finally came to a head a few days before graduation when she asked me over to her place to help her pack. I got the impression that she was having friends over to help her do it, but when I got there, it was just her and me. Her roommate seemed to have already moved out.
Seeing that we were alone, I went in for the titty grab, but she stepped away and said, "I thought that maybe we'd try something more involved. I can tell by the hard-ons you usually get afterwards that this turns you on. So I thought maybe we'd try something sexier. Are you game?"
"Absolutely," I answered smiling. I never imagined she'd be this forward about it.
"Then, to start, get naked." She pulled her shirt over her head, revealing her big white bra, and seeing that she was stripping too, I started taking my clothes off, too. Soon, I was completely naked, and she was only wearing her white cotton panties. I'd never seen her tits uncovered before, and, I have to say, they were fantastic. Big and round with pink, pointy nipples.
"You like?" she asked, waving her chest side to side just a little.
"Very much," I said, but I think my hard cock had already given my feelings away.
"Well," she said, "you can play with them, but as you do, I'm gonna squeeze your balls. Once you take both hands off my tits, you're done."
She faced towards me and grabbed my balls, one in each hand. I put my hands on her tits and began to squeeze and fondle them. As soon as I did, she started a gentle squeezing of my balls. After about half a minute, she began to squeeze a little harder and then a couple of minutes later, a little harder still, and soon I was gritting my teeth to deal with the pain, but I managed to continue playing with her lovely chest. I continued massaging her boobs for about another minute as she slowly tightened her grip more and more. But then she really ratcheted up the pressure suddenly. She was squeezing so hard, that I felt like they were gonna pop. My knees started to knock, and I just couldn't take the pressure any more, so I took my hands off her tits.
She released her hold and said, "you did better than I thought you would."
"Thanks," I said, the pain still clear in my voice.
"I have a little secret to tell you," she said. She paused just a little for dramatic effect, and then continued, "This turns me on, too."
I smiled at her.
"So," she continued, "for the next game, we're gonna masturbate and see who comes first. But, with a special twist. You only get to masturbate when you're standing up, and I only get to masturbate when you're on the floor."
I started to ask a stupid question, "But why would I be on the flo– oh, right."
She smiled with a special twinkle in her eye. "Okay, get stroking."
I was already hard again, having recovered pretty well from the squeezing, and I began to jerk off right away. I had gotten about five strokes when she suddenly kicked me hard in my exposed nuts. Her bare foot struck both balls evenly and forcefully. I crumpled to the floor. She giggled, and her hand went into her panties and I could see that she was her jilling herself off. Watching that helped speed my recovery, and after a couple of minutes, my balls were feeling okay, and my cock was hard again. I struggled to my feet. She stopped masturbating herself, seeming disappointed. I grabbed my cock and started stroking. After three strokes, she kicked me again, even harder this time. My balls were engulfed by pain and I crumpled in a heap once more. This time, I was completely insensible from the ball pain. By the time I was recovered enough to look around and take in my surroundings, she was nearing orgasm.
It was amazing watching her cum while standing over me. She thrashed back and forth in ecstasy, her big breasts bouncing back and forth, and her long slender legs quivering. I almost wondered if she was going to remain standing, but she did. By the end of her throes of pleasure, my cock was an iron bar and my balls only had a dull ache. I stood again, and started stroking. By this point, I was so turned on, that I didn't think it would take very long, and I took advantage of her post-orgasm daze to get myself off as quickly as I could.
After about a minute of stroking I was starting to feel like I was heading towards orgasm when she suddenly stepped forward and kicked me in my naked nuts even harder than the previous times. I fell to the ground instantly and curled up in the fetal position, clutching my nuts.
I just barely managed to comprehend it when I heard her say, "that was sneaky, but sneaky is allowed. We'll do this until I get two more orgasms or until you get one." And then she started masturbating herself again. I just lay there holding my poor, aching balls. After several minutes, the pain was less overwhelming and I looked up at her again. She seemed to be building to a second orgasm, and I decided that since she had interrupted me, I should interrupt her, so even though I wasn't fully recovered, I stood up.
She grunted in frustration as she took her hand away from her clit and glowered at me. I started to wonder if I'd made a mistake. Just as I placed my hand around my dick, she stepped forward and, curling her hand into a fist, smashed it into my testicles with all the force she could muster. It got the right one more than the left and smashed it harder than it had been hit so far. I fell forward onto my knees, brushing against her, and then I fell sideways onto the carpet, cupping my right testicle and moaning loudly.
I was slowly getting a tiny bit acclimated to being busted and managed to stay aware of what was around me despite the debilitating pain. So I watched her quickly finish up the orgasm I'd interrupted. And while I was still moaning quietly, she managed to quickly rub her way to another one. Even with my testicles still wracked with pain, staring up at her as she got off had brought me back to a full and raging boner.
"Well," she smiled, "no cumming for you, I guess. As a consolation prize, would you like to suck on my nipples?"
"Fuck yes," I replied, any pretense of impartiality long gone.
She giggled, and sat down on the sofa. "Here," she said, "put your head in my lap."
I climbed up off the floor and lay down on my back on the sofa with my head in her lap, facing up towards her breasts. She bent down towards me, curling her torso just a little so that her nipples were within reach of my mouth. I sucked eagerly on her pink, pointy nipple, and soon my cock was twitching wildly in the air. After a few minutes, she switched me to the other nipple, which I sucked just as wildly. She leaned over just a bit and began to gently stroke my shaft, just brushing her fingertips up and down along it. She ran her fingertips around the edge of my cock-head and I bucked against the breast I was sucking.
"Please," I begged, "please let me cum."
"Okay," she said, "one more chance. Stand up."
I stood up and she stood too. There was a small bottle of hand lotion on her end table, and she reached over and squirted some on her hand. I gasped as she rubbed it onto my twitching cock. Once I was nicely lubed up, she grasped my cock firmly and did ten slow strokes, counting them as she did them. By the tenth stroke, I could feel myself teetering on the edge of orgasm. After the tenth stroke, she held my cock upwards and suddenly kneed me hard in the balls. I grunted and my knees started to buckle, but I managed to keep it together and straightened up again.
"Good job," she said and then began counting tight, slow strokes to my cock again. I thought that I was going to cum somewhere around 7, but I just didn't go quite over the edge. Somehow I just kept feeling closer and closer, but not quite getting there. At 10, I was the horniest I had ever been on my life, feeling like an additional touch could put me over.
That's when she kneed me again, this time far harder than the last time. My nuts felt like they were flattened, but I could feel an orgasm beginning as a first bit of cum came squirting out. I collapsed quickly to the ground from the pain, but I could feel cum ejaculating from my cock, spilling out onto the carpet of her apartment. She looked down at me and started giggling, watching me curled up on her floor with my cum dripping out.
She seemed to be trying to stop giggling, but just wound up giggling harder. Finally she got control of herself. "I'm sorry," she said. "I don't mean to laugh. That was just so unexpected. I knew you were into it, but I didn't imagine that you'd cum. That's kind of amazing."
I rolled over onto my back and looked up at her. I was still in a lot of pain, but I managed to squeak out a "Yeah."
I continued to lie there for a couple of minutes, but she put her clothes back on. I finally managed to sit up, my balls now having a sharp, but bearable ache from that last hard knee. "Sorry about that," I said. "Do you want me to clean it up?"
"No, that's okay," she said. "There's a carpet cleaner coming tomorrow anyway. There's a whole bunch of stains. That'll just be one more."
I managed to get up and go put my clothes back on. We talked a little about how surprising and amazing the ending had been. And I told her that despite how much my balls ached, I had loved it and would probably never forget the ball busting she'd given me. And she said that she'd had a great time, too. And she told me that she'd accepted a sales job for a corporate security systems company and would be traveling for work a lot and that if she was ever in whatever city I was in, she'd bust me good some other time.
Since then, I've lived in a couple of different cities for a couple of years apiece, but I've kept in touch. We haven't hooked up for a busting again yet, but it looks like the odds are good for another one some time soon.
