"What? The fuck? The cock? Your cunt?" he teased, wanting to hear her say the sexy words that he knew would turn him on even more.
"Yessss! The fuck! Your gorgeous prick! My wet little pussy!" she cried obscenely.
Again, Stu thrust upward, ramming her hard, pounding up into her cunt until her back arched and she bounced on his loins, a babbling, incoherent mass of lust-filled flesh.
"Ohhhhh, baby, baby, baby," Stu moaned over and over again, his mouth slack, saliva drooling from its corners.
Libby's eyes rolled in their sockets, her breathing harsh and labored. Her orgasms continued in a never-ending series of explosive convulsions that tore through the girl's entire body like shock waves.
She clutched her cousin's shoulders, rocking back on his slamming cock, pitching forward on top of him. Then, his arms were around her, holding her tightly to him. His tongue was in her mouth, hers in his, the moans muffled. She pushed down with her juicy, spasming cunt, feeling it being smashed upward as Stu drove into her with the force of a hurled fist.
He drove into her, faster and harder, his strokes like a trip hammer now. He grasped her hips in his strong hands and held onto her, impaled on his cock, his own hips smashing into her with frantic strokes.
She could not squirm in his grasp, could not escape the relentless pounding of his prick, not that she wanted to! He held her fast and felt his own orgasm beginning as her pussy clutched his prick so hard he thought her cunt was going to chew his cock right off!
Stu's cock was a blur of speed, fucking into her dripping pussy with excitingly hard strokes. Libby screamed and bucked, breaking her mouth away from his.
He felt her twisting in his hands, her body writhing orgasmically on top of him. He dragged her down, pulled her hips into his and drove faster and deeper and harder until his cum burst from its sac, shot up the tube and burst forth inside her.
They shuddered together, a long spasmodic convulsion that left them mindless of everything except the powerful orgasm that tore through them.
"Ahhhhhh, commmmmiiinnnggg!" Stu groaned as the last of his cum shot into his cousin's pussy.
Feeling his hot cum splashing inside her, Libby fucked his twitching prick and ground her cunt down on it brutally.
"Oh, Stu, Stu," she moaned, "commmmmiiinnnnggggg!"
