No!
Although, I fucked a married chic for a while.
She was my ex-girlie's best friend and after we broke up she made a move because her husband is a complete stiff and wouldn't fuck her. I told her from day one we weren't dating and I'd never get serious over a chic who was cheating on her husband. She was just too damn hot to not bang her so I couldn't pass it up. After some time she told me she was gonna leave her husband so we could get together.....
She told me this right after we had sex, and I told her she was nothing more than sex and fun and I was never and would never be serious about her. I got up, put my clothes on, and left. That was the end for me. She's tried a few times to talk to me, but I ignore her.
