Her tongue scraped along the split of his ass. The hand on his cheek moved to the small of his back, pressing. Bobby leaned, bracing himself with his hands on his knees. Barbara drew back, gazing at her son's ass with smoldering, excited eyes. His cock was steadily growing in her jerking fist, throbbing. She felt her son tremble.

"Mmmmmm!" she moaned, darting her tongue to the split of his ass.

She ran it up and down the split, lowering her face and trying to tap against his balls. Bobby leaned farther, and Barbara's tongue tasted his balls. Her nose shoved into the crack of his ass. Running her tongue about his dangling balls, she drew it back, sliding it into the spilt of his ass cheeks. The tip licked at his tight asshole bringing a grunt from her son. The heat of his asshole seemed to scald her tongue, and Barbara rammed it tightly, twisting, licking.

Releasing his cock, she clutched the cheeks of his ass, spreading them. The tiny ass pucker winked at her. With a low groan, Barbara shoved her face into her son's ass, her lips open, and tongue wiggling. Pressing her lips around his asshole, she sucked; her tongue licking.

Bobby's cock throbbed and began to drip. Arching his ass back, he waggled it in his mother's face. Barbara tried to run her tongue into his asshole, but it was too tight. She licked along the inner cheeks; tasting the smoothness of his flesh. Again she stabbed her tongue at his asshole, trying to penetrate it. Again she failed.

"Ohhhh, damn!" she cried with disappointment. "Turn around."

Bobby stood upright and turned to face his mother. His cock was up, throbbing, waving. Slipping her hands up the back of his thighs, Barbara cupped his ass, pulling him forward slowly. Bobby watching his mother's face, his eyes glowing. The tip of his cock brushed her lips, and Barbara whimpered softly. His cock slid along the side of her nose. She shoved her tongue out as his balls rubbed across her lips. With a cry of pleasure, Barbara pulled her son's balls into her mouth. She sucked and licked them, digging her fingers into his ass cheeks.
