So did you enjoy yourself last night? I can't believe I ALLOWED you to do THAT. Most stepmom's would NEVER allow their stepsons to have their girlfriends over. It was because your stepdad was away on business otherwise he'd forbid it. I hate to admit it but I got jealous. I want to be your one & only. I tried giving you two privacy but couldn't. I heard things and HAD to listen.  The door was cracked open. I could see EVERYTHING. I saw the outline of your girlfriend's head under your covers sucking your dick. I think you felt me watching. Was she a good cocksucker?  Mmmm I bet!  It made me so inappropriately horny watching you get pleasured. Such naughty, dirty talk I heard coming out of your mouth as you pushed her head down into your dick. She's a good girl, right? You filled up her belly real good. Mmmm. It was fucking hot. Then it was time for you to fuck her mmm. And well, I just HAD to keep watching and pleasuring my OWN body too.
