"Sit up on the edge of the bed for me, will you? Hurry, Mark!"

Mark did as his mother asked, sitting on the edge of the bed with his giant fuck-tool throbbing wildly up in front of his belly. Sharon felt her pussy creaming heavily as she slid off the mattress and knelt before him. It was, she thought, high time for a long session of mother-son cock-sucking.

She wrapped her fingers tightly around the bloated fuck-tool looming in front of her face, again marveling at its thickness and stiffness. Then the horny, naked mother started pumping her fist rapidly up and down in a skillful hand job. Mark shuddered with pleasure, sticky cum-juice bubbling more heavily out of his pisshole, running onto his mother's hand.

"Does this feel good, baby?" Sharon mewled. She jacked her hand fast, staring at his cock-head, watching the pre-cum ooze out in obscene little squirts. "This is how you do it to yourself when you beat your cock-meat, isn't it? Do you like the way Mom's beating your cock meat for you?"

"Yes!" Mark cried. "Oh, yes!"

"Then I'll bet you'd like it even more if Mom did a little cock-sucking," Sharon said excitedly. "Would you like that, baby? Would you like your own mother to suck off this big, throbbing cock?"

"Yes, yes! Oh, please!"

Sharon slid her cum-slicked fingers to the root of his massive boner, preventing it from throbbing so violently. Then she opened her mouth wide and plunged her lips over his cock. She forced her head down until she was nearly choked herself on his cock with half of it jammed into her gullet.

Sharon shut her eyes and locked her lips in a tight, compressed circle around the blue veined stiffness of her son's fuck-meat. Then she started sucking, very hard, bobbing her head and slurping noisily around the tasty stiffness of Mark's cock.

It was delicious, the biggest, stiffest, tastiest cock she'd ever sucked in her life. Sharon had been a little obsessed with cock-sucking during her late teens, and had gone through a period in which she'd tried to coax the cum out of a different set of balls every day. But her son's cock was the biggest and best-tasting of all. Sharon really knew that she would never get her fill of sucking the hot spunk out of her own son's cock.
