Then Mitch sat up on his knees, withdrawing his mouth and fingers from her throbbing cunt. The moment Karen saw his grinning face she knew that her trick was being turned against her.

"You fucker," Karen said hoarsely. "Don't you do this to me!"

"Turnabout's fair play, teach!" Mitch smiled.

Karen thought for a moment, then, with one swing of her arm, knocked the papers and books off her desk. She crawled onto it and wiggled her ass to the edge facing Mitch, again spreading her legs and planting her heels on the side of the desk, opening her pussy for the invasion of his bone-stiff prick.

"I guess you get to fuck me, Mitch," she whispered. "Then we both get to cum. Come on now! Ram my pussy full of that big, hard dick!"

The desk was low, so that as Mitch stood he wouldn't have to bend over far to fuck his cock into her. Rising to his feet, the strapping youth held his jerking, pulsing prick in his fist and pushed the cock-knob onto the syrupy slit of her pussy.

They were both too horny for any kind of foreplay. With one savage thrust, Mitch fucked his cock all the way into Karen's sopping cunt. Immediately he started to fuck her pussy hard and fast, moaning as her cunt tunnel sucked around his prick.

"Ahhhhh, fuck it!" Karen cried. She shook her head deliriously back and forth on the desk and whipped her ass frantically off the hard wood, pumping her hairy pussy onto the boy's fat prick. "That's good, Mitch! Gonna cum, making me cum! Fuck me, fuck me faster! Unghh! I wanna cum so much!"

Mitch dropped his hand to her tits, hungrily rolling the huge, spongy tits under his palms, feeling the stiffness of her dark-red nipples. He began to pant as he wildly fucked his bloated cock through the gurgling sheath of her pussy, feeling her cunt slit nip his prick with every thrust.

"Gonna cum, Mitch!" Karen cried repeatedly. "Keep fucking me, fuck me hard! It feels so good up my pussy! I said I'm gonna cummmm! Fuck me, I'm cumming, oh God I'm cuuuummmiiinnnngggg!"
