You pig!!! You fucked my stepmother!?!

After he's been away for 2 weeks, I'm incredibly happy that my boyfriend is finally back. I go out and buy some nice underwear to surprise him with. When I cum home, he's lying on the couch and my stepmother is with him. They are acting a bit strange, but I don't think anything of it yet. So I send the old woman away and lock the door so we can be undisturbed. In the heat of the moment, I even forget the condom. Anyway, we've been together for a long time and we love each other. After he fucked me and jerked me off (which was much less than usual), I was looking forward to cuddling with him. But then I found a pair of panties between the cushions of the couch. They belonged to my stepmother. That lousy pig had actually fucked her. What am I going to do now? How the old slut seduces my boyfriend, you can see in the video "Cum to mother-in-law" in the profile of @Texaspatti.
