My Step-Mom's Secret

Zac Wild walks into an empty house after class and starts yelling for his dad and stepmom Silvia. Nothing. Snacks sit on the counter next to some weird jug labeled 'Magic NURU Gel' like it's normal household shit. Zac scoops it up to stash it back in their room when he hears this low voice behind a door talking about spreading gel all over a body. He cracks the door for a look and catches Silvia stretched out naked on a rubber mat, slicking oil across her big tits, rolling those stiff nipples under her fingertips. Girl's in her own world, practicing some sticky massage technique. Zac's got his hand straight down his pants before he even thinks. Then his belt buckle clangs off the door frame. Silvia whips her head around, loses balance, starts sliding. Zac lunges to catch her and ends up with two handfuls of slippery tits. She freezes mortified. Doesn't want his dad finding out about her 'alternative medicine' hobby. Zac says she should practice on him instead of risking Dad's wrath. She fights it, but the logic wins. Minutes later she's pouring the thick gel down his back and smearing it across her own chest. She climbs on, tits pressing into muscle, grinding her slick pussy along his spine. Flip him. Zac's cock's standing hard, and Silvia wraps her hand around it without hesitation. She works more gel into her cunt, then sinks down, riding her stepson in long slow strokes till they both finish with a grunt and a grin.
