Recently me (m22) and my gt (f21), we always go out with her and her friends at our local college bars, and she has about 4 girls we constantly go out with and it's always really fun. We usually pregame at one of their apartments and the last time during pregame, when her friends come out all dressed and ready, she was calling them hot and complimenting them obviously as they do look great. then next thing she tells me is that I can tell them they look hot as well. I got nervous like I thought it was a joke but I could tell she was being serious so I gave my opinion and told her how sexy the outfit she had on and my gf seemed to not be bothered by it at all which I just have never experienced before. Later that night at bars we were quite drunk and one of her friends has the most perfect boobs. My girlfriend caught me looking at her once and then started whispering all night to me how sexy her boobs were and it turned me on so much cause I know she now likes me looking at her friends it appears. Later in the night we had our normal sex routine the only thing different was to finish me off sometimes we watch porn together, but this time she finished me to a pic of her and her friends and I loved it. I am unsure if going out in the future if this is gonna be a thing or what just wanted to see if anyone had a similar experience and what it led to?
