I pushed her blouse and bra together up under her chin and lowered my mouth to suckle her. Like a hungry c***d I took her right nipple in and sucked h...ard. I teased her nipples with the tip of my tongue, I sucked them, I squeezed her tits. Her hips started making circles so I moved my right hand to her pussy again without taking my mouth off her left nipple.

She shoved me back onto the couch and straddled my face lowering her pussy down to my mouth. I didn't do anything at first, and she got aggressive and said, "Eat my pussy you little bitch, I made you cum...now you start eating and don't stop till I tell you to!" She ground her pussy down on my lips. It was. Billy went wild as I finger fucked Mom right in front of him.

I sucked them clean and said, “Go ahead feel up my mother.”Billy called out for a Pepsi too. It took Mom a little extra time to get her courage up and come back into the room. She stood between Billy and the coffee table, she opened her stance to allow him better access, and then Mom bent over.Billy took so long. Perhaps it was the urgent necessity to reaffirm her basic morality, after having succumbed to this inexplicable temptation, for to keep quiet now would be essentially a condoning of the whole sordid mess. Whatever it was, Lisa had kept the dog with her, going around the school in a determined attempt to find out who its owner was. Once she knew, she could perhaps confront him -- or her -- and receive some partial satisfaction that way. But nobody she'd talked to knew... or would admit they did..
