Now I'll leave you to your reading, enjoy)

It was a warm saturday in your country like you've witnessed many before. The sunlights were already crossing the thin fabric of the curtain in your room. Your body was slowly booting up, and beside you ? Was your futanari girlfriend sleeping soundly.

Tania was a 25 years old futanari with incredibly big, bouncy and perky F-cup sized breasts that rest proudly on her torso, a fairly slim waist attached to her big and plump ass, a rather fit belly due to the exercises you motivated her to do, silver dyed hairs and charming brown eyes that cought your attention the first day you both met. All without forgetting her smooth dark skin that has never been violated by any kind of ridiculous amount of fat. And of course, a package nobody is suspicious of when she walks outside in her casual clothes.

Today was a day like any other day.... Or maybe not. The thing is, it has been a couple of months since you've started watching those "ballbusting" videos. You were intrigued by the genre of these videos related to hurting, punishing and sometimes completly destroying their partener's sex.

Of course most of them were fake but you couldn't stop yourself from imagining yourself doing it for real. The thought of someone having the other's sex life in the palm of their hand and decidinh wether they'd destroy it or just torment their partner before sparing them, had turned you on more and more while looking at those videos and luckily enough for you, your girlfriend here has balls ! Balls that are begging to be completly shattered. At first you didn't really want to destroy them as it would result to an end for your other favorite sexual activities with her. But looking at her shamelessly exposing them before you, completly unguarded, while you were struggling with your demons made you change your mind quickly. You had to find a way to relieved this need for dominance and destruction. You just never found the time with your studies, diet, job applications, etc... Your life was not a "mess" but you were certainly busy.

After keeping those desires inside of you for too long, today was the final day of your denial. You straighten up slowly beside your girlfriend who was still sleeping beside you. Your eyes walked over her body taking in the sight of her raising topless breasts with only a tight boxer on perfectly embracing her hard on. You turned to her side slowly moving your finger tracing her jawline, drawing the curves of her body, caressing her nipples, then made your way with a feather like move, to her bulge. She was really hard. Just what you'd expect in the morning...

After that you moved to her balls and slowly parted her legs away leaving her genitals defensless. You didn't hesitate to give them small but solid taps to test how full they were. Then suddenly, you grope her balls roughly and tightened your grip on them making her flinch slightly before moaning deeply from the sudden feeling of discomfort. Thankfully, Tania was an heavy sleeper, and I mean, really heavy sleeper. Funny to think that one of the phew things that usually annoy you with her, will be really handy to you now.

After playing with her cock, you stand on fours over her sleeping figure. Your arms pinned her against the bed on both sides of her head. Your legs were crossed together between hers, then after aiming for the best possible angle, you threw your knee right where her innocent balls were resting.

"Oogh-hng !" She proactively groaned with her soft voice. Her body instinctively curled forward but her brain didn't seem to be awake yet.

"Shhhh~" As she called your name with confusion you slowly stroke her hairs to put her back to sleep, and believe it or not her eyes slowly closed back and she went back to sleep under your gentle touch with her hands still cupping her poor babymaker. And this only turned you on more.

But this could not end this soon, Tania was an easy prey. And her feminine testicles were going to crack today... No. Matter. What. All you had to do was decide how to proceed with her now.
