Billy stopped with his cock pushed as deep into her throat he could manage. "Wow Mom, you are quite the little cock sucker you know that?" He yanked her off his cock.

"Is that a compliment son?" Rachel sneered up at him.

"Maybe. Let's see if you can still give a good rim job." Billy replied. Still holding his mother by the hair he half dragged half lead her to the bed and tossed her on it then straddled her face. "Get to work." Rachel extended her tongue out slowly and pressed it against her son's rectum. "That's right, dig in." Billy groaned grinding his ass down against her tongue. Rachel jammed her tongue up into her son wriggling it back and forth until he started to squirm. Instead of letting him do as he wanted she wrapped her arms up around his waist holding him down while her tongue continued it's lewd invasion. "Oh fuck!" Billy gasped leaning forward on the bed. His mother didn't stop, she slithered out from beneath him and continued lapping at his ass, reaching around to stroke his hard cock. Rachel felt Billy's hips lurch, then his cock started pulsing in her hand. That only made her move faster pumping his dick in rhythm with her tongue until he came and collapsed in his own semen.

"Is that enough? Is that what you wanted from your whore mother?" Rachel taunted. "You know I used to fuck for a living, against guys who made their money by not cumming. You're just a little boy."

For a moment Billy just lay still but then he rolled over. "I'm not finished with you yet Mom."

"Yes you are. You've cum twice in the last hour and you're dru-" Rachel stopped mid word and found herself staring at her boy, specifically at his still hard cock bobbing defiantly in front of her. "You've got to be fucking kidding."

Billy grinned. "Nope, now get up on the bed." Rachel obeyed crawling up onto the bed. Billy grabbed her by the hips easily manhandling his mother so her face was buried in the pillows and her ripe rump was pointed invitingly skyward. Rachel spread her legs slowly urging her child on with a low desperate groan. He didn't keep her waiting either, Billy thrust his cock into her so suddenly her head bumped against the headboard.

"Harder! Harder baby, Mommy's about to come." Rachel placed her hands against the wall and pushed back against Billy, matching each of his brutal strokes. It had been years since the last time she'd had a man just fuck her. Billy didn't need to be encouraged. Even if she'd been begging him to stop he wouldn't have. Not until he came.

Suddenly the depravity of what they were both doing hit both of them and mother and son came together. Rachel was howling like a banshee, later she'd have to explain to the neighbors how she was a having an affair with two young studs which was a much less interesting story than the truth. Billy on the other hand was completely silent taking a few last thrusts before he rolled onto his back utterly spent.

"You are amazing." Billy whispered.

"You're not half bad." Rachel panted.

"C'mon lets go take a shower." Billy said sitting up. Rachel looked at her son then obeyed.
