In the cramped shower stall, stepson Nick Floyd and stepdad Derek Allen stand under the streaming water, their bodies pressed together. Nick's heart races as Derek's hands roam, exploring his smooth skin, tracing the lines of his muscles. When Derek's lips press against his, Nick hesitates, but only for a moment. He kisses back, tentatively at first, then with growing passion. They soap each other up, their hands sliding over slick skin, exploring every inch. Nick drops to his knees, taking Derek's hard cock into his mouth, feeling it throb as he takes it deep. Derek pulls him up, pressing him against the cool tile, his fingers finding Nick's asshole. Nick gasps, pushing back against the intrusion, wanting more. Derek gives it to him, fucking him hard and fast, their bodies slapping together, the sound of their moans drowned out by the pounding water. Nick takes it all, his own cock rock hard, leaking pre-cum. Finally, Derek pulls out, Nick turns around, and they share a final, hungry kiss, their bodies slick and spent.
