OMG i fucked my stepson by accident

I got home from a girls night out and creep into bed with my boyfriend, I'm so horny from all those margaritas! So I get him to fuck me! And it's so good! His cock felt different! It felt thicker and bigger! The next morning I'm making breakfast for the both of us, but it wasn't my boyfriend standing outside the kitchen... it was my STEP-SON! HOLDING MY BRA! I freak out, I tell him it was dark, and I was tipsy and that I obviously didn't mean for that to happen! And he tells me he will stay quiet if I let him take pics of me, I get mad, but I ultimately accept seeing no choice... besides I enjoyed that good fucking he gave me!
