Steve's cock was throbbing, transmitting the pulsations through her hand; up her arm, into her body, then down to her cunt. She was very wet inside her bikini, and her clit seemed ready, to burst through the material. Her eyes burned as she stared at her son's cock and balls. She knew now that he was ready for girls, ready for cunt, for fucking.

As if obeying silent signals from her cunt instead of her brain, Mary's fingers closed about her son's cock. She held it tightly, then thrust her fist up and down. Steve gasped, but he remained still as she jacked up and down his throbbing prick, his eyes wide with surprise and excitement. Removing her hand from his cock, she gently cupped his tender, precious balls.

"Mom, what's going on?" Steve asked.

"Shush," she mewled, twisting her son's balls in a loving way. "Just be… don't say anything, Steve."

Her voice came out in a husky whisper, her eyes gleamed with desire. She slowly licked her tongue over her full, moist lips and, although she knew her face was falling lower and lower, she couldn't stop herself.

"Ooooh!" Steve gasped, his eyes shining as he looked down at his mother's face so close to his cock. "Mom!"

"I said hush," she whimpered.

Her tongue snaked from her mouth, and she touched the tip in a feathery way upon the swollen smoothness of her son's cock. She felt and tasted the throbbing heat there. She sucked in a deep breath, then lapped her tongue along the smooth head of Steve's cock.

Steve gurgled, twisting his naked ass that still hung over the edge of the bed. Mary's mind was burning with intense desire as she moved her tongue about the head of her son's cock. She knew this was insane, but her body, especially her twitching cunt, was telling her not to stop.
