Rachel grinned at the fetal ball of whimpering male suffering beneath her as a quiet involuntary moan of anticipation escaped her lips.
She gently placed a sandalled foot on Paul's hip then quickly shifted her body weight to roughly jerk his pelvis down to the floor, forcing him out of the fetal position unto his stomach.

She smiled briefly as the sounds of his moans and sniffles reached her ears despite his face firmly burrowing in the basement carpet. He was unable or unwilling to move as his feeble legs spread enough for his battered balls to be seen protruding temptingly from under his ass.
Rachel slowly walked into the V between his legs, slipped off her sandal, and stepped firmly on his aching nuts. The young female tormentor giggled joyfully at the feeling of Paul's soft balls squishing between her little toes as he desperately tried to close his parted legs and reach for her ankle, squealing pitifully into the carpet.

Laura barely payed attention to her little sister's brutal ****, focusing instead on the sweet squeals of male agony, as she continued her own self-gratification. Working on her clit, she rubbed steadily and vigorously, bringing herself to the edge of orgasm before shifting her hand. The girl inserted two fingers into her dripping tunnel and focused the thumb on the clitoris above, digging inside her pussy with the thrusting lower part of the hand while steadily rubbing the erect pleasure button with her thumb. The jolts of pleasure from each source of stimulation didn't take long to bring her to the pinnacle of climax, as an eruption of intense pleasure burst through her body, her juices gushing out onto the old basement couch. Laura panted rapidly, relishing the waves of pleasure washing over her body.

Rachel raised the heel of her foot, placing all her weight on the toes planted firmly on Paul's organs and concentrated to maintain balance in that position, only falling back on her full foot for a second before resuming the agonizing toe stance. She giggled uncontrollably watching Paul's legs flail violently as he gave up trying to stop the young girl's persistent onslaught and screeched dejectedly into the carpeted floor.

She maintained this exercise until her toes grow numb, abruptly stepping off her classmate's throbbing orbs to recuperate.
Paul curled back into a fetal ball at her feet, covering his swelling nuts and whimpering softly.
