My gf is 22 Latina, Sometimes I trade her partial nudes online (nothing more than bare ass at max, no nipples or pussy). I find it really hot. Anyways so Me and my friend were out at a bar and we were watching some boxing matches and started to fumble around the idea of making bets. He joked about me being broke (I’m a struggling college student lol) and said I had no money to bet. He then said it’d have to be something else “like nudes” I asked what he meant then he laughed and said he’s joking. Another match went by and I asked what he meant again and he said we could bet our gfs nudes. Then quickly said he was joking. I told him I was down for that and he pretended to think about it and agreed too. We are both in 3 year relationships. After a few fights and a few bets, we both owed eachother a few pictures. As I was driving him home we exchanged pictures. I never found his gf attractive but seeing her like that was really hot. We started of with lighter pictures and then got a bit more dirty. We ended with pictures of our girls bent over spreading their asses. I never showed anyone my gfs tits, let alone her asshole and pussy.. me and my friend talk about what happened openly and joke around but haven’t done it since. I have this other friend with a wife that I want to do something similar with now. She’s gorgeous. I just don’t even know how to even try doing that. Feel free to give me advise or ama.
