"I told you nothing happened, just stop," the young man tried his best to push her away, but it was useless. She slammed him back against the toilet seat, the plastic rattling under his weight. Her skirt was already hitched up to her waist, revealing her dripping pussy that was already soaked and glistening. She quickly straddled his lap, enforcing her muscles with mana to double her strength, making it impossible for him to move his legs. She raised her ass up and shoved his face into the valley of her tits, suffocating him against her sweaty skin. She reached down with a firm grip and dragged out his bulging nine-inch cock. It was a monstrous piece of meat, thick and veiny, looking far too large for his frame. She gripped the base, positioned her soaking wet hole right over the head, and dropped.
"Argh!" he moaned directly into the sweaty skin of her breasts.
She clenched her teeth, her face twisting as the monstrous meat forcefully widened her tight hole, stretching the skin to the limit. She didn't just sit; she forced her weight down with a violent shove, literally screwing herself onto his cock until the very root was buried inside her. The instant his head hit her womb, the young man's body spasmed. He instantly flooded her internal walls with hot, steaming cum, his balls tight as he pulsed load after load into her. He began thrusting his hips upward, trying to empty every drop into her, his hands digging into her slender waist.
"Ahhh~! Ahh! Ahhh~!" She moaned like crazy, her voice echoing off the stall walls as she hugged his head tighter. She was cumming hard, her internal muscles squeezing his nine-inch rod, but then her ass began to move again. She wasn't finished. She was determined to break him today. She wasn't just slamming down anymore; she was forcefully screwing and unscrewing his cock, twisting her hips in a circular motion that ground his cock head against her cervix.
The pleasure hit the young man so hard his brain overloaded; he froze in a soundless scream, his mouth wide against her tits. She kept going, her ass having a life of its own as she milked him. Her buttocks bounced and slapped against his thighs.
PAH! PAH! PAH! PAH! PAH! PAH!
The sound of wet skin clapping against skin was deafening. White juice and internal fluids splashed out of her entrance with every impact, coating his balls and his thighs. His rod was foaming from the sheer friction of her tight, mana-strengthened walls. She went into a total frenzy, moving her hips at a blur, her pussy sucking on him like a vacuum. She was milking the young man dry, her body convulsing as she hit peak after peak, but she refused to let him go. She wanted him to belong only to her; she wanted to make sure he could never get hard for another girl after this.
"You're mine... ahh! Only mine! I'll break you... ahh~!" she moaned through grit teeth.
She spread her legs even wider, her knees hitting the sides of the stall, and bit down on his length with one final, violent drop. The impact made her massive tits jiggle and bounce against his face. The young man squeezed her waist so tight his fingers pressed deep into her flesh, his arms nearly touching her bones through her skin. Her ass flattened under the sheer pressure of his grip. He slammed his cock upward one last time, squeezing it dangerously against her womb, pinning her internal organs with the tip of his meat.
Her eyes rolled back until only the whites were showing. Her tongue lolled out of her mouth, saliva dripping onto his shoulder as her body fought back in a physical reflex from the maddening, brain-numbing pleasure. That was when he shot the final, heaviest load. Thick, white-hot cum blasted into her womb, filling her to the brim. His legs trembled uncontrollably, his eyes rolled back, and a guttural grunt left his throat as he reached a peak so intense it felt like his heart would stop.
Right as they were locked in that final, shaking convulsion, the door to the stall was kicked open. Standing there was a young girl, her eyes wide and her expression completely shocked.
"WHAT?!"
