My, How You've Grown!

Zac Wild struts into the parlor dripping sweat. His step-mom, Chanel Preston, thanks him for hauling that busted couch. "All good," he pants, "just worked up a sweat." Grinning, he lifts his shirt to mop his face and shows off cut abs. Chanel lets out a hungry little gasp. "What?" he asks. She chews her lip and drinks him in. "You got big since you turned 18," she admits. He shrugs, still the same dude under the new muscles. Shifts toward the door, says he'll shower at home. A glint hits her eyes. Why not here? Towels already waiting. He laughs and agrees. Steam curls around Zac as the water beats down. Chanel edges in, eyes glued to his wet frame. She squeezes her thighs together, hand drifting over her shorts. Need drowns caution. A towel hangs near the stall. She palms it, slips closer. Throws her voice loud as she rounds the corner. "Brought you a towel!" she sings, faking shock. He laughs, says he's been naked around her before. She eyes the thick V that disappears into soap and admits maybe things did change. He reaches back, struggling. She offers to scrub him down. Reluctant at first, then he gives in. Her slick palms glide over slick skin, touch growing bold. Suddenly her fingers wrap his cock. He jerks away, chest tight. She flashes her sweetest smile, offers a NURU rub to calm every sore muscle. He takes the bait. Gel glistens across his back in the massage room. Chanel climbs on, skin sliding over skin with slow, filthy strokes. Grunts leave his mouth. Flip, she tells him. Now her tits graze his chest, bellies kissing, her soaked cunt dragging across his thigh. His cock hardens fast, thick as a forearm. Chanel bites her lip, says his biggest muscle looks pretty tense. Happy to help. She grips him tight; he sucks in a breath. She marvels at how grown her boy got—about to show her how much bigger he can still get.
