He felt his balls tighten. He had merely entered her, and already he was so very, very close. Justin looked away from his mother’s lust contorted face, staring at the blank wall, and counted to ten. Her cunt tightened around him. She made small mews and cries that he barely heard through the blood thundering though his ears. He looked down, into his mother’s stormy blue eyes. She winked at him.
Justin slowly eased his cock out of Diane’s clasping pussy. He grinned at her and began to fuck in earnest, slamming his cock back home with a grunt.
“Yes!” Diane cried out. “Oh my fucking God, yes!” Strands of black hair clinged to her face, but the rest of her mane was spread out beneath her. She threw her head back and cried out, “Fuck me, Justin! Fuck me, baby!”
Like a good boy, Justin did as his mother told. His cock sawed in and out of her, thrusting and jabbing, piercing her deeper and deeper with each forceful stab. He slammed into the roof of her womb again and again, the spongy tip of his cock expanding each time it connected, and he felt as though his dick were getting harder and bigger with thrust. He couldn’t believe how hard he felt, how wet she felt, how tight her pussy was.
Again and again he fucked into his mother, growing more savage and desperate with each movement. Justin had no technique, no skill, no experience. But he had a great deal of exuberance and repressed emotion, and he slammed away with all the force he could muster. Every time he pulled out, his mother moaned, and each time he stabbed home she cried out. Her hips rose up to meet his with equal ferocity. A froth of their combined juices formed at their joined crotches, matting Justin’s pubic hair and staining Diane’s pubic mound.
Her tits bounced against his chest. Justin ducked his head on a downstroke and captured a nipple between his lips, sucking lightly. Diane’s fingers left his shoulders and found the back of his head, threading through his hair and kneading his scalp.
Her pussy tightened around his cock as a fourth climax roared through her body. Her fingers dug into the back of his head, pressing his face into her tit as she came. “Oh Justin, my baby, my son,” she groaned.
With effort, Justin pulled his head away from Diane’s heaving breast. He jabbed his cock deep inside her and held his cock there for a moment, her muscles clasping him tightly. “Mom,” he moaned, “I’m gonna. . .”
“Oh,” she said. “Let me see it,” she gasped. “Let me see you cum.”
Justin groaned. His balls tightened. He felt a tingling at the base of his cock. He yanked himself free of her pussy with a sucking sound and raised himself up on his knees. His distended cock pointed across his mother’s belly, throbbing and pulsing.
Diane raised her head, eyes bright, and stared at her son’s cock. It was slick and shiny with her juices, and its head looked as though it had swollen in size. The little eye winked at her, and suddenly a long arc of pearly white jism jetted from his cock, across her belly and tits. It splashed against her chin and lips.
