Feeling guilty

I'm a 19 year old girl and I recently fucked a married man. He's my older brothers friend andI met him in a club and agreed to going back to his that night.His wife was away for the week. We hadn't been in for more than 10 minutes and we started making out.I wanted to stop but I was incredibly horny.He was also so damn good.He ate my pussy till I came so I pulled his dick out,it was so big and such a strong erection,I sucked it.Then he spread my legs and slid his 9 inches in me.Yes he really had 9 inches. He fucked me so damn well,like a real man I would do anything he wanted of me. After my 2nd orgasm I wanted him to cum and to finish in me.I thrust my hips into him and he fucked me even harder.Then he groaned and came in my pussy.I felt him push right in as he came and that made me start cumming again,he noticed so he kept ploughing me and after we lay there for a while.When he pulled out I sucked his cum covered dick clean.
I've felt so guilty for doing that but I couldn't resist.
