3 women. The first one was an older woman that I knew from a friend and we hooked up at the end of the night during one my friends house party. Several years later I was dating an older woman and she enjoyed it...the first time was after having sex for a while and I got her to let me rim her. THis was a first for her and she instantly loved it and it progressed to me cumming inside. From there it was an integral part of our fun.

Yes, I would...I love to rim but my wife is not that into it unfortunately.

I am bi and I once played with a husband and wife who were both bi. I was sucking the husband's cock and his wife came up behind me and slid her strap-on in my ass. It caught me off guard at first because it was bigger than any guy I had played with before but I quickly adjusted to the size and it was such a euphoric experience. Sadly that only happened once but I would want it again.
