Talked to sister on the phone - shamelessly waxed!

An unbelievably huge cumshot that hits me in the face. And I've got my sister on the other end of the line! I always tell her everything and she knows that I fuck my flatmate's boyfriend, grin. Anyway, I was just about to tell my sister about my last video shooting experience when the guy arrives and wants to fuck. He pushes me, just like that. But just because I don't join in straight away, he starts wanking. And what can I say, in the middle of the conversation, he hammers a mega load of cum into my face - or rather right onto my mouth, oh my God. So much cum! I couldn't speak properly, the sperm was already throwing bubbles. Do you think my sister noticed? Mean or?
