"Shove, Jimmy!" she yelped, "Shove it in me!"

"It is in, Sharon," he croaked.

"Not all of it!" she squealed. "You're supposed to get all of it in me! Shove hard, Jimmy!"

Jimmy shoved.

A sharp pain shot through Sharon as his cock stabbed into her cunt. But it was so quick, it made no impression on her. The pain felt searing, but then there was an amazing feeling. She couldn't believe how good it felt to have his cock in her cunt. She felt full, stuffed to her stomach, her cunt stretched so deliciously.

"Oooooh, Jimmy!" she howled. "Ohhhh, that feels so good in me!"

She wiggled her ass, her fingers clutching and clawing at the bedspread, her eyes half-closed, feverish, panting and sobbing with the greatest pleasure she had ever felt in her young life. She writhed and twisted her ass, feeling her brother's cock throb between the tight lips of her cunt.

Jimmy seemed frozen en top of his sister. Her cunt gripped his cock as hard as his fist ever had, only it felt a thousand times better.

"Pump, Jimmy!" Sharon gurgled. "Pump up and down! You know, like you did your finger!"

Jimmy started pumping slowly, thrusting his cock in and out of his sister's clinging cunt.

"Ooooh, yes!" Sharon gurgled, twisting her naked ass. "That's how it's done! Ohhhh, go a little faster, Jimmy!"

Jimmy speeded up.

He lifted himself up, bracing his hands on each side of his sister's shoulders, trying to look down, watch his cock move in and out of her cunt. He saw his cockshaft lift upward, glistening with wetness. Sharon tucked her chin down, trying to see, too. She couldn't see anything at first. Then she saw the base of his cock.

"Ohhhh, look at that, Jimmy!" she whimpered.

"Yeah!" he groaned. The sensations of having his cock inside a cunt for the first time in his young life were overwhelming. He began to stab fast and hard into his sister's cunt.
