I have thought about my best friend's wife for years (also my gf best friend). She has a amazing body and a ass to die for (honestly the best ass i have ever seen). We went over to there place. We hung out for a while. When my friend's wife and i where alone we went into their room. We fucked eachother and i came inside her. She is not on anything (no birth control. my friend and her want to get pregnant) and i didn't use a condom. It was the best sex I ever had. She loved it. We have never done anything before but we will be in the future. Her ass felt as good as it looked. We both have talked afterwards and agree that we want to fuck every chance we get. She told me she shouldn't be ovulating. Now we both can't take our minds or thoughts off eachother. We want to fuck eachother again all day every day. I have told her I loved cumming inside her. She loved it to. She and my best friend are trying to get pregnant so we both deside for her to get the pill. I have told her that i can't pull out and that she has to be in control of that. She said she wants me to cum deep in her pussy. I couldn't resist. She can't use the pill now.

What should i do. I have very strong feeling for her but I love my gf and she loves her husband (my best friend).
