Back in the day gf and i were into some cuck stuff. We never did anything but talked about it openly. I was more into it and she played along. One day she came to me and said a friend of hers ask her if she would be interested in having a threesome with her and her boyfriend. it was her friend's bf's bday and her friend wanted to do something special for him. seeing an opportunity i asked her if she was interested. her friend was hot and my girl was bi. she admitted she was curious. i told her to go for it. she was a little reserved and basically asked if i was sure i was okay with it. i promised her i was and my only ask was that they took some pics so i could enjoy later.

She talked to her friend (who was surprised to learn my girl was with me - she thought my girl was single when she asked) who agreed she was fine with pics for me. The day came and my girl headed out to go see them. about 30 mins later get a text on my phone. her and her friend laying naked on a bed together. text follows "about to fuck them both - thanks man" cleary from her friend's bf. instantly rock hard knowing shes probably getting fucked in that moment.

few hours later she comes home. instantly bring her to the bedroom and she starts to undress. her pussy is red and swollen. asked her how it went and she said it was basically him fucking her for a few hours while his girl watched. he didn't wear a condom (one of the things i thought we discussed) but she was on birth control. asked her if she liked it and she said "yea". fucked her brains out and came so hard.

still get rock hard to the pic to this day. she ended up having sex with them a few more times and 1 other couple we met online.
