The ripe-titted housewife lay sprawled out on the bed. Her fingers were buried inside her pussy and she raised her full ass off the bed.

Jim Dorman dropped his bathrobe from his arms and sat down on the edge of the bed. "How come you're so horny lately?"

"What do you mean?" Lisa said, her fingers racing over her pussy-pulp. "I'm no hornier than usual." But she was and she knew it. Lately she'd noticed how fast Billy was growing up and just thinking about his hard, lean, teenage body was enough to make her cunt throb.

"Don't get mad, hon," Jim said. He was naked now and Lisa's eyes darted over his body.

"I'm not mad," she said softly. "It's just that I'm hot."

He shrugged, his big cock swaying as he climbed onto the bed. The blue veins on his shaft throbbed and his cockhead was swollen. Lisa licked her lips in anticipation. Maybe tonight she'd suck him a little before they fucked.

"What's the hurry?" he said as he stretched out on his back.

The brunette thrust a finger into her pussy. Her curly-haired cunt-flaps touched her finger and she stroked her cunt with her thumb. She thought about Billy and blushed. "Maybe it has something to do with my period. I'm so damn hot."

She stuffed a second finger into her gash and humped her ass off the mattress. "Fuck me, Jim."

He yawned. He turned onto his side and gazed at her. "I'm a little tired tonight, if you want to know the truth."

She reached for his prick. It was hard. "If you're so tired, how come you're stiff?"

He chuckled. "Reflex action, I guess."

She pumped his dick until it was completely hard and he rolled around and knelt between her widely splayed legs. Her heart beat faster when she realized he was finally going to give her what she needed. A good hard fucking.

She thought about her son and spread her thighs wider apart. The thought of Billy's crotch kept coming to her mind. She remembered how his cock had looked when he'd been small. Even as a baby he'd had a big one. But for the past few years he hadn't let her see him naked. Just when he was really getting interesting, she thought with a smile.
