She fucked up and down, meeting the thrusts of his cock with sobs of ecstasy, her cunt trying to consume him, his whole body. The steel-like shaft of his cock fucked deep into her clinging cunt lips. Her pussy contacted the rough fabric of his jeans. And Susan loved it, loved the slight pain those jeans gave her, knowing her thighs were being scratched… and caring only that his cock was plunging into her steaming cunt at long last.

Bobby was biting into her sensitive nipples, and even that felt good to her. His tongue fucked her nipples as his lips sucked. She felt one of his hands underneath her twisting, grinding ass, clawing at a smooth ass cheek. She tossed her hips up and down wildly, frantic to have his cock as deep as she could get it. Her skin was rippling and tingling and her toes curled. She was yelping and squealing as her mind reeled with the most intense ecstasy she had felt in years.

"Oooo, fuck me!" she cried hotly. "Fuck my cunt, darling! Ram my pussy… burn my hairy cunt up with your hard, sweet cock! Ohhh, give it to me, balls and all! Fuck me… fuck your Mary!"

The hot moans of her son increased her pleasure, as did his snorting breath against her swollen tits. The way he dug his fingers into her resilient ass cheeks caused her to throw her burning cunt even more frantically up to meet his cock.

She became frenzied with her movements, her ass churning up and down in a violent way, almost causing her son's cock to slip from her pussy once or twice. The grip of erotic ecstasy guided her motions, her mind, and she was powerless to control herself.

"Fuck moth… Mary!" she screamed, catching herself just in time. She did not want to shatter the fantasy for him. She had to keep building on that fantasy so he would not become embarrassed. At least, that was how she thought at this time. "Fuck your hot-assed Mary, Bobby! Fuck her hairy, hot cunt raw! Make her pussy come, darling, make her come with your hard, sweet cock!"
