step-Dad Discovers That His Wife Has Been Fucking Their step-Son

I'm fucking my husband in missionary and am so bored. I hardly feel a thing and wish I was fucking my step-son instead. I then take a bath with my step-son and apologize for having sex with his step-father. We've been having sex behind your step-father's back for a while now and it's been great but all of a sudden he wants to come into the bathroom. I try and prevent that but he barges in but I manage to put your head under water. The next day in the kitchen we are having another argument but you sneak in and lick my pussy, then my asshole. I later let you know how much I enjoyed that and you fuck my ass until you cum on my face and tits. Your balls are still full so you fuck me some more and finish inside of me, then again on my tits. Suddenly step-dad walks in and is shocked, but I tell him that this is the new reality and he can take it or leave.
