Donald was still fast asleep upstairs. Impulsively, Vivian rose from the chair and rushed into the hall. Her big, braless tits bounced heavily under her bathrobe, and she could feel the leaking fuck juices squishing lewdly between her inner thighs.

She'd told herself only minutes ago, when she'd awakened, that she would never, ever fuck her son again. But seeing Richie's hard-on as he ogled his mother's ass had made Vivian incredibly horny.

She was a dirty son fucker, Vivian thought, climbing the stairs two at a time. She was as horny as a bitch in mating season. Her pussy was throbbing, and she craved her son's stiff, fat cock.

Donald was fast asleep in his room. Vivian shut the bedroom door softly behind her, shrugging off her robe as she crossed to his bed. Gingerly, she sat on the edge of the mattress. She stared at Donald's face as she pulled the covers slowly to the foot of the bed.

He was naked, sleeping on his back. Lovingly Vivian gazed at the thick tube of cock meat resting across his thigh. She hefted his cock on her fingertips, curling them around his cock shaft to lasciviously massage his prick. Immediately, his cock started swelling in her hand.

Oh, fuck, what a filthy slut I am, Vivian thought, as she commenced the slow, hard hand-job. Donald sighed in his sleep, arching his ass off the bed, fucking his stiff cock through her fingers.

Vivian released his prick. She shuddered with fuck passion as she watched the boy's hard-on twitch and throb in an arc over his belly. The cock knob was already oozing thick, milky drops of pre-cum.

Curling onto her side beside her child, Vivian slurped unashamedly as she sucked in the first several inches of her son's cock shaft.

Donald's eyelids fluttered as he began to awaken. By that time his horny, naked mother was sucking his prick extremely hard, lovingly laying her tongue around the flared tip of his prick.
