Father of girlfriend nibbled. Am I a slut?

I've had the hots for my girlfriend's father for a while now. When she was out, I went to her house and waited for her father in the living room. When he finally came, I wasted no time and made it clear to him straight away that I thought he was horny and would like to fuck him. I have to admit that I was a little surprised by his reaction, because he had obviously been wanting to lick and fuck my little pussy for a while. We did it right in the living room, but when we were finished, I felt guilty. Am I a bad girlfriend? Am I a slut?
