Paco, the older of the two, can't resist his stepbrother's youthful allure. He pins Luis against the wall, his thick cock sliding into Luis' waiting hole. Luis gasps, his body tensing as Paco's length fills him completely. They move to the bed, Paco fucking Luis missionary, then switching to doggy style, their bodies slapping together, their moans echoing through the room. Paco pulls out, cumming all over Luis' back, before they share one last kiss, their taboo lust satisfied.
