Caught FREMDFICKING !!!!

Actually, the boyfriend of my best girlfriend only wanted to show me one of his new tattoos, but I was so horny that I really wanted to feel his fat cobra in my cunt and since his girlfriend still had to change the parking lot, I thought that we still had some time and it would not be discovered. So I let him fuck me secretly in the bath. He fucks me really hard and dirty. My tits shake and I have to suppress my screams and then suddenly his girlfriend is standing in front of the door.....Fuck, what do I do now?!
