Denise was sitting on the couch watching the game, when suddenly she found herself getting more and more distracted by several thoughts, all of which involved Andy. Eventually she couldn't take it anymore and stood up. She left the room and headed towards his room. Without knocking she entered to find him sitting on his bed looking longingly at the duster in his hand.
"Forget that thing" she grinned lustfully, "How about you help me out instead" she added with a knowing glance to her crotch. Andy followed her gaze and licked his ruby lips sensually.
"Oui Madame" he replied as he climbed off the bed and onto his knees before her. He slowly pulled Denise's boxers down and began to kiss her inner thighs and just above her groin. He smiled to himself as he felt his mother quiver with each kiss. Finally he brushed his tongue over her clit, which felt hard and swollen, and she let out a small gasp of pleasure.
"That's it baby" Denise cooed, "now suck it!"
Andy was more than happy to oblige as he wrapped his lips round it and let his tongue dance. AS he did so he could feel it begin to swell more and more, and his mother clit began to stretch further into his mouth. Soon he could feel slight pulsations forcing it to grow wider as well. With each pulse Denise grunted, and oddly she could feel her pussy getting dryer and tighter. She grabbed her sons head and pulled him off, standing him up and leading him to bed. She pushed him down forcefully and stradled him so her now 6inch long clitoris hung above his face. She pulled down his panties and began to lick the tip of his penis. Andy resumed his sucking as two balls dropped from within her vagina leaving no trace of the opening that was previously there.
With each stroke of her tongue Denise could feel her son's member shrinking. She placed two fingers between his balls and began rhythmically pushing them in and out. Each push seemed to move further and further into his body as his penis shrunk at the same rate. Before she knew it she had pressured his balls all the way into his body, the sack forming two moist lips which her tongue was now lapping at hungrily.
