Hey you’re here early!” Sempai shouts, bursting in through the door, her cape flapping behind her. “Umm, I'm not here early. Actually, it's already nine thirty-five, so you're late!” I retort, returning to the book I was reading. “Oh, hehe, I guess you're right! But ugh, don’t worry, my diligent assistant! I know just how to make it up to you!” Sempai whisked over to where I’m sitting with a mischievous grin spread across her face. “Now You are just making me nervous… what are you up to sempai!” “Well, you see, all men have one weakness, but if I could turn that weakness into a strength, maybe we could use it for a trick!” she said, suddenly holding up a picture of a perfectly anatomically accurate man. “W-what are you getting at!?” I say, genuinely starting to worry about what she has in mind. “It’s the TESTICLES, of course! You see, they're full of super dense little nerves that fire off incredibly quickly when they're hit, causing an extreme amount of pain!” She proclaims proudly, pointing to the crotch of the man in the picture. All I can do is gulp. What does sempai have in mind?! “But, everyone knows that… Sooooo if I use a hypnosis trick on you, and make it so that you testicles aren't super sensitive, we can pull off some amazing tricks!” My jaw dropped. Was she… “Are you serious?!” I yell, wondering what I did to deserve this! “Of course, my faithful assistant! We’re going to make some amazing ballbusting magic!” “No, no, no, no! There’s no way you have to be crazy!” “Awww, come on, it’s just your balls! Hmmm… What if… we did this first?!” she said before tackling me to the ground. “Ouch! Huh!? Why did you… That hurt!” I groan, my back stinging from suddenly being smashed into the floor with the weight of Sempai on top of me. “You… umm… like these, right?” Sempai says, slowly taking off her blue sweater, revealing only her bra underneath. “Waaaah! I… I mean… why are you!?” “D-don’t make this awkward, assistant! L-look, I’m going to… hypnotize you with my… boobs, and then your testicles will be… strong!” Her stutter getting worse as she starts to shake her chest. “Uuugh… Sempai.. I dont know… if…” my words fall out of my mouth slowly, as if I’ve inherited her stutter. “Yes! S-see, it worked! Now, let’s test your nuts!” Before I can react, Sempai brings up her knee and then slams it hard, straight between my legs and into my balls. “Yes, direct hit! Right in the balls! How are you, assistant?” “Oooooooh!” was all I could mutter. The pain was overwhelming, and it was as if I could still feel her knee driving into my nuts! My mind almost went blank, and all I could do was reach to defend myself, but Sempai was in my way! “See, it’s no big deal! Your testicles are like steel balls now! Let’s try again! This time, full force!!” Again, her knee came up, and I saw it float for a second before she launched it straight down, and this time she did a little jump, putting all her weight into her knee as it crashed into my jewels, flattening them both! “SEMPAI!! MY BALLS!!” I howled as the pain exploded through me. Every inch of my body was flooded with pure agony. I felt it. I felt her knee actually compress my poor nuts with all her weight… Fuuuck, it hurt sooo much! “Oh, come now! You're just being a baby… and a loud baby! Hmmm, I know how to silence you, though!” Slowly and methodically, she twisted her body while remaining on top of me and shifted her weight so that her soft legs wrapped around my head, before she plopped down with her soft ass directly in my face. “Now, let’s try again! Sempai's steel ball attack!” She yelled before raising her fist and smashing it down on my already throbbing balls! This time, however, the pain was different. I felt it in my throat, rising like a banshee’s wail, but as I opened my mouth to scream, something warm and wet muffled my face. I realized that my cry of pain directly funneled into her... underwear!! The sudden sensation was like nothing I had ever felt before. It was as if the pain itself had turned into a vibration that was now resonating through my mouth and into her most intimate area. Sempai’s eyes widened for a moment, surprised by my involuntary reaction, before an embarrassed look spread across her face. "O-oh.. assistant.. I didn't expect.. that! Mmmm, that feels... kinda... nice! Maybe I Should, keep going!" Sempai moaned slightly before raising her hand yet again, this time with a devilish smirk playing on her lips. Her hand swung down with a sadistic grace, and I felt the crushing impact of her fist against my sack. The pain was so intense that it seemed to travel through every inch of my body, but before the scream could escape my lips, the warm, moist cavern of Sempai's pussy dampened it once more. My howl of agony reverberated through her, and she gasped, her body convulsing slightly. The pressure was unbearable, but the sound was trapped within her, a symphony of suffering that seemed to resonate with something primal in us both. "Oh god, that's... that's amazing! You.. you have yo scream more! Scream for your sempai, assistant!!" I could feel her slightly shuffling around, pushing her bitt backwards and making sure her pussy was directly in line with my mouth... but then I felt something else. Her hand slipped down my pants and quickly wrapped around my balls. "OOOOH, NOOO NOOO, DON’T SQUEEZE MY NUTS, NOT MY NUTS!" But the sound was lost, turned into Sempai’s pleasure, and only motivating her further. Her grip tightened around my balls, and she massaged them with a rhythmic cruelty that had me writhing in pain. Each squeeze sent a fresh wave of agony through me, and I could feel her body responding to the vibrations of my muffled screams. Her pussy grew wetter, the sound of my voice echoing within her, turning into pure ecstasy for her that seemed to pulse through her very core. "YES! YES... MAKE YOUR SEMPAI CUM, LOUDER, SCREAM LOUDER!" Her own howls now filled the room, and for a second, she released some pressure on my aching nuts... only to squeeze them the hardest I've ever felt. "OOOOOOOOOOOOOOHHHHHHHHHH!" I howled into her pussy, the sound reverberating through her lie waves of bliss crashing over and over again into her. She dug in with her fingers, compressing every nerve in my trapped testicles. Sempai's eyes rolled back into her head as she felt the vibrations of my anguished cry, her breathing becoming erratic and shallow. Her hips began to rock harder, grinding her wetness against my face, the smell of her arousal pouring into me. "T-This is.. it... assistant... I... I can't hold it!!" The sensation was intoxicating, and as I felt her begin to climax, she clamped down on my balls with everything she had, flattening them to half their size and pushing every painful button possible. Her body arched, back bending as if hit by a bolt of lightning, and she let out a scream that seemed to shake the very foundations of the room. Her muscles tensed, and I could feel the vibrations of her orgasm in her grip, a symphony of pleasure and pain that washed over her in waves. Her legs tightened around my trapped face, a vice grip that held me in place as she bucked her hips, riding the crest of her climax. The wetness grew, a warm river that flooded my mouth and nose, and the scent of her liquids was all I could smell. Her breathing grew ragged, and she let out the most feminine moans that pushed her into pure ecstasy. Her body quivered and spasmed, and in that moment, her eyes rolled back, and her pupils dilated as she reached the peak of her pleasure. Her grip on my balls was still like a vice, each twitch of her hand sending a new shockwave of pain that seemed to resonate with the pulsing of her own climax. It was pure pleasure for her, and absolutely torture for me, but finally, after what seemed like an hour under her, she slowed down and Sempai slowly slid off of me, allowing me to curl up into the fetal position, nursing my poor jewels. “Oooh, that was incredible, assistant! I’ve never felt anything like that before! Your screams... they were like... like...” she couldn’t find the words to explain it. I'm sorry about your... testicles... but... at least we learned right, hehe~ If this keeps up, sempai is going to break my balls!!
