My step-mom has been away on a business trip for the past month in California so she left you, my stepdad, in charge of making sure I don't have parties or get into trouble while she is gone. One day I get a call from my best friend who told me she saw you on Tinder. She decided to swipe right to see if you matched with her and you did. I barge into your room extremely mad that you would cheat on my step-mom with some random slut on the internet. You beg me not to tell her but the only way I won't is if you teach me how to fuck. There is a guy that I like in one of my college classes and I want to be prepared when we fuck. You resist at first, but then you finally give in. I have had a crush on you ever since you married my step-mom, so this is going exactly as planned. I tease you first by slowly taking off my skirt and my top, showing you how wet my pussy is. Before we fuck you tell me I have to use a condom even though I am on birth control. I agree and you tell me how to put it on your cock. I ride you in the cowgirl and reverse cowgirl position as you teach me how to fuck you correctly. When you are about to cum, I tell you to look in my eyes and give me a signal so it will be hotter whenever you cum. I pretend your dick slips out of me and I sneakily remove the condom. I put your cock back in raw and you cum inside me. I show you that you came inside my pussy without a condom and you get mad. I apologize and tell you that I just wanted the full experience.
