My, How You've Grown!

Zac struts into the massage parlor, dripping sweat and breathing heavy. His step-mom Chanel Preston flashes him a grateful smile. 'Thanks a ton for hauling that beat-up couch to the curb,' she says. 'No sweat—literally,' he shoots back with a grin, wiping his forehead by yanking up his t-shirt. Boom—there’s his ripped six-pack, gleaming under the lights. Chanel gasps, eyes widening like she just hit the jackpot. 'What?' Zac asks, smirking. 'Oh, nothing... just...' She trails off, raking her gaze over him slow and deliberate. 'I mean, since you turned 18 last year? You've bulked up like crazy. So damn big and strong now,' she purrs, nibbling her lip. 'Hey, living together makes it easy to miss the glow-up,' he laughs. 'But I'm still me under it all.' 'Oh yeah, my sweet boy,' she murmurs, fighting a losing battle not to ogle him head to toe. He clears his throat. 'Gonna head home and scrub this grime off.' But then—lightbulb moment for her. 'Whoa, hold up. We've got a killer shower right here. Rinse off quick? Beats stewing in your own funk on the drive.' A sly flirt edges her voice. 'Eh, why not?' he chuckles. 'Saves me the car-seat sauna.' 'Precisely!' She beams as he heads off. Alone, she taps her chin, plotting like a fox in the henhouse. Cut to Zac under the steaming spray, soaping up smooth. Chanel sneaks a peek around the corner, eyes locked on his slick, muscled frame. Heat builds fast—she bites her lip hard, hand slipping down to rub her pussy through her skirt, breath hitching. She tries to bail, but nah, she's hooked. Temptation wins the tug-of-war. Spotting a towel on the rack, she snatches it sneaky-like, heart pounding. Deep breath. Then she struts in, all innocent. 'Brought you a towel!' she calls, popping into view by the stall. 'Oh gosh, sorry! Thought you'd be done!' Fake shock sells it. Zac just laughs, easy as pie. 'Chill, Mom. You've seen the full monty on me a million times—no biggie.' 'Guess some things never change, huh?' he teases. 'Mmm, not so sure...' Her stare devours him, bold now. She's not his bio mom, but she raised the kid—remembers him all scrawny and awkward. Now? This stud. She clocks him struggling with his back. 'Want a hand?' Hesitant nod from him. Game on. She lathers him up, and whoosh—the vibe turns steamy quick. Hands glide sensual, steam thick as their pulses race. Then her fingers wrap around his cock, stroking firm. Zap—too much, he jerks back. But she's not quitting. 'Hey, how about a massage? Loosen those sore spots.' He caves. In the massage room, she flips him belly-down, slathering NURU gel over his back like liquid sin. Then she slides her naked body atop his, grinding slow and slick. He melts into it, eyes shut, low groans escaping. 'Roll over,' she whispers. Front side now—her curves press and rub against him, skin on skin electric. Friction sparks wildfire. His dick twitches to life, stiffening proud. She spots it, lip caught between teeth. 'Looks like you've got one hell of a tense muscle there. Let me work that out.' Her hand claims his shaft, pumping deliberate. He gasps sharp. Chanel's mind reels—her boy's all man now, and he's packing heat that's about to prove just how much bigger he can get.
