She slid up his belly.

"Mop me up, Chuck!" she moaned. She jerked her pussy into his face, and the cunt-hungry youth slurped up the seepage with relish.

Then the nimble girl twisted around and took his semi-stiff cock into her mouth, sucking all of their combined juices from the rubbery meat.

"Wanna fuck again, Sis?" he rasped. She considered for a moment. She nibbled on his prick while she pondered the possibility of further sibling incest.

But then, with an impish grin, she shook her blonde head and said, "Let's save it." Chuck raised his eyebrows.

"If Mom goes shopping, we can suck and fuck in the big bed," Frostie said.

He grinned – more a grimace.

"Yeah! I can make believe that I'm throwing the cock to Mom!" he grated.

"And I'll pretend I'm fucking Daddy!" the delectable daughter responded.

This, obviously, had a profound effect on their listening mother. It seemed that her children were as hot to fuck with their parents as she was to have sex with them.

Things were going to work out fine. Chuck and Frostie got dressed and went back down through the trap door.

Rachel, sticking the rubber cock back up her cunt, came across the attic and knelt on that door. There was a gooey puddle glistening on the wood where cunt-cum and jizz had dribbled down Chuck's groin when his sister had been riding on his cock.

Rachel lowered her head and licked it up.

It was scrumptious.

And that family-oriented lady could just imagine how much more succulent it would be when she was drinking it straight from her son's cock and tonguing it from her daughter's pussy.

Her mind was made up.

She lapped up all the second-hand slime. Then she gave her cunt a last pounding with the rubber cock, creaming off once more.
