So I moved in with my best friend and her husband earlier this year (2011) and everything started off really cool. Then one day I was going in for a shower, turned it on then went back to my room to get my towel and hair products. So when I go back to the bathroom, my friends husband is in there, naked, about to get in the shower. He heard me open the door and we saw each other naked (accidentally). I felt so embarrassed! My best friends husband and I had seen each other naked! I quickly closed the door and went into my room. Thankfully my friend wasn't in the house at the time.

After a few minutes he knocked on my door and came in, we discussed what had happened and agreed that we should keep it to ourselves.
Over the next few days I noticed him looking at me in a very different way. I felt embarrassed still, but found myself thinking about him more and more.
Finally, one day when my friend had left early in the morning for work, I bought it up, he said he has been thinking about me more and more and I said the same. We ended up kissing, which led to us going into their bedroom and having sex. I was ashamed, but I also couldn't help but feel amazing. He touched me in ways I've never been touched before. He went down on me and got me so wet, I came all over him and the bed. I then repaid the favour. And we had amazing sex. The best I've ever had in fact.

After, we changed the sheets and didn't talk much more for the next couple days. But then it happened again and again and again etc. It's been nonstop for a while now and I really want to end it because I hate doing this to my friend, but it's just he makes me feel amazing when we have sex. One side of me won't let me stop having sex with him, the other wants me tell and leave the house. The worst thing is my friend has no idea and thinks her marriage is better than ever.

Seriously don't know what to do!
