Step-Mommy Finds Johnny's Used Condom And He is in Trouble

I come home and there's my step-mom Melanie on the couch, pinching a used rubber between two fingers like it's Exhibit A. She found it under my bed. Guess my old man always had a hunch I was knocking boots up there; this proves it. I figure I'm screwed—Dad's never been big on girls spending the night. But Melanie? She's eyeing the stretched-out latex, clearly impressed by the size, and the next thing out of her mouth is, "Let me see the real thing so I know it's yours." Five seconds later I'm out of my jeans, dick in hand, rock hard while Dad's supposed to be at work. Or maybe he isn't. Either way, Melanie's already pulling her shirt over her head, and I'm about to rail my own step-mom on the couch like it's the last forbidden fuck I'll ever get.
