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

I can not believe my Step-Mom just goes snooping around in my room, I had just got home when my step-mom Melanie is sitting on the couch holding a used condom. She found it in my room, my parents had some suspicion that I was having sex but this just confirms it. I thought I was in deep trouble cause my Dad never liked me bringing girls over the house but to my surprise, Melanie was turned on by how big the condom was, she asked to see my dick to make sure it was from me. I can not believe I am gonna fuck my step-mom while my dad is at work..... or was he.....
