Vivian and Lana had grown up together in a small town in the south, remaining inseparable until their marriages had separated them. Vivian had married, given birth to Donald, divorced and retired to a pleasant life as a single mother with a generous alimony check.

Lana's husband, on the other hand, had died in a tragic car accident only a month ago. The next day Vivian had heard from her former best friend for the first time in years. Would it be all right, Lana had asked tearfully, if she and her own son Richie came to stay with Vivian for a while?

Vivian had agreed immediately. Lana and Richie had now been living with Vivian and Donald for two weeks. There were no problems, except one big one.

Ever since the divorce, an increasing amount of sex play had developed between Vivian and her son. It had seemed harmless at first, but it wasn't harmless anymore. Tonight Donald obviously wanted to fuck her, and Vivian was beginning to wonder if she had the willpower to stop him.

"No, Donald!" Vivian gasped, trying to push his mouth off her straining nipple. "No, Son, don't you dare touch my pussy! Ungghh! Get your hands out of my panties, Donald! Nooooo…"

But the tit-sucking son had finally managed to work his fingers under his mother's panty crotch. Vivian hissed as she felt his fingertip probing between the wet, swollen, pouty lips of her hairy cunt. She grunted loudly as his finger wormed deep inside her gooey fuck tunnel.

"No, Donald! Stop it, Donnie! Awww, noooo!"

Slurping on her fat nipple, Donald fucked his finger to the knuckle of his mom's burning, itching pussy. Vivian was painfully conscious of his long, fat prick throbbing on her thigh. She gasped as her son started finger-fucking her cunt.
