Do it a lot! Susie giggled to herself. Her mother was pretty foxy, but in some ways she was prim. Well, the years will tell. Lisa had to be at least thirty-five. She'd been married very young and had Susie and Billy tight away, but still, she wasn't a kid anymore.

Susie pictured her Uncle Bob naked. At least she tried. She'd seen him in bathing shorts many times, but she'd never seen him undressed. Now that he and Tina were living next door, maybe she'd have an opportunity. God, her pussy dripped just thinking about it!

She thought of Billy upstairs in his room and wondered what he was doing. He was probably jerking off. She thought about her ex-boyfriend, Cliff. Since they'd broken up a week ago, she hadn't gotten laid once.

Now she made a sudden decision. She was horny and Billy was probably upstairs jerking off. It was silly to waste a perfectly good hard-on. And, God knows, Billy walked around with a constant hard-on. She'd just go upstairs and see what was happening. If she wound up in bed with him, well, so what? Wasn't that what it was all about?

In fifteen minutes Susie was in bed next to him, stroking his cock.

"Jesus!" he said.

"You ever do it before?"

"Sure."

His fingers trembled as he reached for her tits. When she'd walked in on him, she'd quickly stripped her clothes off and climbed into bed beside him. He'd been in the middle of jerking off and her presence so shocked him he almost lost his hard-on.

Now she pumped away at his prick. She sat cross-legged with her wet cunt totally exposed. Her muff was thick and curly and golden blonde. Different from Tina's dark one.

"You ever do sixty-nine?" Susie said.

Billy grinned. "Yeah."

They climbed around and lay down on their sides, head to foot. Susie sucked his cock into her mouth and started licking his cockhead while she squeezed his balls.
