wife's friends buttholes

I’ve seen one of my wife’s friends buttholes. Ha. Such a specific inquiry. I’ve told the story here before but we were drinking with some friends and one of her friends had a summer dress on and had removed her underwear to try on this goofy Viking underwear thing that my roommate had received as a gag gift. It was part of a drinking game dare. When she switched back to her dress the underwear never went back on. After a while we were all pretty drunk and she was messing and flirting with my roommate who was not at all interested as he had a girlfriend. At one point she lunged at him and he turned away and she fell backwards over the coffee table. The way she landed was on her back with her legs in the air facing me. I saw EVERYTHING. Haha. Pretty funny and sexy moment.
