Everyone is different when it comes to rules. My ex only did anal with family members. She enjoyed being gang banged and she enjoyed sex with other women. I enjoy rubbing frotage. Its an awsome feeling that i cant describe. I have a dildo, butt plug, and my girlfriend pegs, but nothing beets the feel of a real cock.
It is quite erotic. Feeling another cock rubbing on mine and mine of his inside a willing pussy is about the best feeling ever. Yes you feel the entire cock of the other man and her pussy too. First time with me with a friend and a woman we both knew. she wanted to do it and arranged a meet with the two of us and two other bi guys she knew. I laid down, and she climbed on. she bent forward and my buddy slid inside her easily, she was really ready! Only a few minutes later I shot my load in her and my buddy kept going. soon she told me she was not ready to cum and sat up, moved forward and sat on my face. My buddy moved to put his cock in her mouth as I ate her pussy full of my cum. She finally came and my buddy filled her mouth. Then the other two guys took turns in her mouth too! It was all great fun! Try it, you will like it.
