My gf and I have a fairly new occasional partner who plays with us from time to time that we met at one of our first times at a Lifestlye Club. My gf and I enjoy anal, and do ATM on occasion, but its not a common thing for us, and she will only do it when things are drying up and we need more spit on there. The woman who plays with us and every few minutes of anal she will do it. One of her ground rules, though, is that she won't ever do it from my gf's ass. We have had numerous group experiences, and other men/women join us, so we def respect that rules are rules, but I really dont see how it can be that worse out of someone else ass vs your own. Does anyone have experience with this?
