Step-Son, why are you home? I thought you were spending the night at your girlfriends! You had a fight?! Oh no what happened. You two were getting sexual and you accidentally called her step-mommy?!! OH NO!! It's all my fault! I’m a horrible step-mommy, wearing provocative clothes around you always. step-Son! Why do you have a massive boner? Because your girlfriend didn’t finish satisfying you and now you’re thinking about fucking step-mommy?! Okay step-son, since it’s my fault you are so hard, I’ll take care of it for you. But only this once, then you need to stop thinking about me sexually!!
