My boyfriend's dirty little secret

All characters in this story are at least 18 years old.

Hi, my name is Lea, I'm 24 years old, with long, black hair, dark eyes and a nice rack with firm, perky C-cup boobs. Today, I want to tell you about how I found out about my boyfriend's dirty little secret, and how I got to enjoy his kink just as much as he did.

It was a slow day at work, so I took a half day off and hit the gym before I returned home. When I entered, I found my boyfriend Dave in his home office, his working notebook right next to his private one. When I came in, he looked at me like a dog who had been caught stealing food from the kitchen, quickly clicking something on his screen before looking up.

"Ohhh... hey honey, you're early today." he said a bit too casually not to raise any suspicions. I stepped around his desk and let myself fall onto his lap, hugging him and giving him a deep, passionate kiss. Curiously, I threw a glance at his screen but there was only his desktop. I noticed the size and hardness of his cock and began wiggling my butt a bit on top of it. He instantly moaned.

"Someone is excited to see me, hum?" I teased him before leaning in for the next sensual kiss. "Are you done or gotta work a bit more?"

"Oh I'm pretty much done. But I still wanted to go for a quick run." he said and slapped my butt playfully to make me get off his lap. I jumped off, a bit confused why he was so horny, apparently, but not that eager to engage with me.

I watched him getting dressed for his run, excited and a bit horny myself. After he left, I took his notebook that we usually used to watch Netflix together and laid on the couch. When I opened the browser, a window appeared, asking if I wanted to restore my previous session. I instantly wanted to click 'no', but I halted. His surprised reaction, the boner that couldn't have grown as fast as I had taken to stride around the table... The curiousity about what he had been doing was too much for me. I tiny peek wouldn't hurt, I thought, and clicked yes.

I found myself on Reddit and was even more surprised that Dave had an account there. He didn't use any social media at all, usually. The only sub he was active in, was one named "BallbustingStories". With astonishment, I began reading one of the stories that he had up-voted.

The process, my mind went through, while I read the story, was amazing. At first, it felt really strange to read the description of a guy who was disrespectful to his girlfriend. When she decided to give him a hard kick into his groin, I laughed out loudly. Now this was what "ballbusting" meant.

The initial amusement and astonishment quickly gave way to something else, when the story got into a detailed description of what the guy felt, physically and emotionally. It instantly had me hooked on a very sexual level. With my mouth opened in wonder, I quickly finished the story. Somehow, the whole concept was dripping in erotic, I had to admit.

In high school, I had kicked a guy in the nuts once. He had been a total douche and I had simply decided that he deserved the pain, nothing more. Little had I known of what it really *meant* for a guy to get his testicles kicked by a girl.

Suddenly I noticed that I had unwittingly played with my left breast and nipple while reading the story. I was actually horny as fuck. Not only the written concept, but the memory of the hulking football player falling to my feet as a result of my sneaker rocketing into the nice, meaty bulge in his groin was insanely arousing.

I quickly read another story, and another. Before long, my hand had slipped under my jeans and I began touching myself down there. At first touch, I nearly came. Reading through the stories of men getting their balls kicked, punched or squeezed by mean girls, I was edging like never before in my life. 

Dave especially loved couple stories, as far as I could tell. And he loved when the guy didn't know or understand why his girl was doing this to him. The concept of non-consensual, sensual busting was actually incredible.

Suddenly, I heard a noise in front of the door to the living room, quickly pulled my wet fingers out from my jeans and closed the browser. Dave came in hot and sweaty, and with that amazing bulge of male pride and vulnerability in his tight running shorts that instantly got my attention.

"Hey babe, I'mma take a quick shower." he just said in passing, not aware of how I ate him up with my eyes alone. For a moment, I thought about confronting him with what I had found, but I quickly bit my lip. There was a *much* better approach to this.

When I entered the bathroom, Dave was already nude and in the shower. A glass wall separated the large shower booth from the rest of the room, allowing me a wonderful view on his strong, ripped body under the running water. My eyes instantly wandered down to his large cock and the nice, meaty pair of balls.

Trembling in arousal and anticipation, I quickly stripped naked and stepped into the booth, too. My nipples were rock hard and aching a bit, when I stood behind him, and the tickling, wet arousal in my crotch was killing me. I estimated the right distance and pulled back my right leg a bit. The suspense was so intense! Taking a deep breath, I tried to calm down.

"Hey hottie!", I called out, teasingly. In the moment, he turned around, I launched my foot up towards his groin. The expression of shock and his desperate flinch made me stop halfway through the kick, while I involuntarily began giggling. Watching the large, strong guy jump in anticipation of a threat to his genitals was so funny, somehow.

"Relax babe, I'm not gonna kick you *down there*." I pressed out in between giggles. His desperate attempt to hide his disappointment and regret for his instinctive reaction behind a relieved act was beautiful. His rapidly inflating cock told a very different story.

I opened my arms, pursed my lips and stepped closer. With opened arms and wide legs, my tall boyfriend leaned in for a hot kiss, eager to feel my nude body against his. A moment before our lips met, I closed my eyes and mercilessly pulled up my knee in between his legs.

"Ouuuhhhffff", I heard him grunt while a wonderful rush of sexual power shook my body. The sensation of his large, elastic orbs pressed against the hardest part of my thigh, just above the knee, was marvelous. So marvelous, that I had to leave my leg there for a moment, flattening the sensitive pair against his unyielding pelvic bone.

I shortly recalled the detailed descriptions of the fictional male characters getting their balls busted by their naughty girlfriends and opened my eyes to look at Dave. His face was a wild mix of agony, surprise and awe. Emphasizing with his sensations and emotions while his balls pressed against my thigh, suddenly pushed me over the edge. Bare any recent stimulation of my pussy, I came with a surprised, loud pant of deep joy and desire while my body shivered from the colorful pleasure spreading into every last cell of my female body.

Finally, I withdrew my knee from his testicles and let him fall down onto his butt. The look he gave me from below was so funny, that I had to laugh out in the climax of my intensive orgasm. His mind obviously failed to process, what was happening, while he knew that he had been promoted to the heaven of his deepest desires and dreams. The water running down and making it hard for him to comfortably look up at me made it even more amusing.

"Show me your balls!" I shortly and dominantly demanded, as he had cupped his manhood with both hands. Without hesitation, he lifted his arms and grabbed my butt with both hands while I stepped under the shower head in between his legs. Dave sat on his butt, his legs spread as widely as the shower booth allowed. The pair of vulnerable testicles was resting on the bottom of the booth right in front of my feet, his raging boner pointing up at me.

Without hesitation, I stepped onto his balls with the front of my right foot and tossed my left knee over his shoulder. Despite the orgasm that had finished barely seconds ago, I was so fucking desperate to come. Dave's painful scream was muffled by my pussy when I pulled him in with my calf.

The instant, incapacitating sensation of deep, sensual delight made me forget about the sensitivity of his genitals for a moment. I threw my head back into my neck and moaned deeply. When Dave desperately tapped my butt with both hands, I became aware of the pressure on his balls by the front of my right foot and reduced it a bit, instantly feeling bad for him in a very naughty, fetching way. 

Fortunately for my boyfriend's testicles, I came very fast. Unfortunately, I loved it so much that I was instantly craving for more. My bright, delightful screams filled the steaming bathroom while I was lifted to unknown levels of sexual bliss and ecstasy. The sensation of the squishy, vulnerable pair of male reproductive organs under the sole of my foot was insanely uplifting. Also, it gave me the perfect leverage to reward or punish him into submission to use his tongue just as I desired him to. Good lord, he was good like this. After the third, rapid orgasm in a row, I pushed him away, took my leg off his shoulder and released his testicles. 

"Up!" I strictly demanded, a second before I bent down and grabbed his nuts to pull him up by them. When my hand closed around his swollen testicles, he instantly complied and struggled to his feet, his knees weak and trembling. Dave's face still looked like he was unable to process any of what was happening. The sudden desire of his girlfriend to hurt and control his vulnerable balls left him in a state of scared admiration and painful bliss.

I roughly pushed him against the wall of the booth and got onto my knees in front of him. After seizing one of his testicles in each hand, I couldn't wait to suck on his raging hard dick. It was so full and massive that I had trouble getting it into my mouth. After all the sudden ball torture that I had put him through, I really wanted him to enjoy this. The more he did, the rougher I would be able to treat his manhood the next time, I figured. 

Every time, the pulsing of his raging cock increased when he was about to cum, I withdrew my face and focused on squeezing the hell out of his balls while looking up at him with a naughty, challenging smirk. At first, he bent over and tapped my head. Another few squeezes later, I had him moaning, and soon after, he openly begged me for mercy.

"Oh Lea, babe, please don't break my balls... Oh gosh it hurts so much. Please, be gentle." I fucking loved it. I considered finally letting him cum, but I was too horny to allow his cock to become flaccid again. Smirking at the disappointment and terror in his face, I let go of his manhood, pushed myself to my feet and stepped back. 

After kneeing, stomping and squeezing his balls, I still wanted to give him the normal kick that I had not pulled through before. Dave became aware of my intention much too late. My leg was so fast and merciless that there was nothing he could do. When I felt Dave's bare, large balls slap against the top of my foot, I quickly recalled that high school football player again. It was crazy that I hadn't been aware of the sexual implication of my action back then. This simple, effective kick was such an amazing statement for female superiority and dominance.

Before my boyfriend could fall onto the floor, I caught him and pressed him against the wall again. Then I turned around, bent over and let his massive, hard cock slip into my pussy. It had been at most three or four seconds since that mean kick and his moans of agony indistinguishably turned to moans of extreme pleasure from both of us.

The last stage of our sexual interaction was over within seconds. When I reached back in between my legs and grabbed his balls, it became too much for both of us to take. With his amazing cock pulsing and twitching deep inside of me, another wave of unimaginable well-being shook my body violently. 

Panting hard, I arched my back up and leaned against Dave's muscular chest, turning my head for an intimate sideways kiss while the sensation slowly ebbed off. When our lips disengaged, I listened to my boyfriend's panting. He was obviously desperately trying to find the right words to conclude what had just happened.

"Oh babe... I fucking love you!"
