I had dropped hints to my gf that I liked my friends looking at her. She never seemed to respond well, or she would just brush it off. In the many years of our relationship she hardly ever dressed provocatively anyway, which is why the idea of it was so hot to me. She is curvy, blonde, and has beautiful pale round chubby boobs with large pink areola that would poke out of a low cut dress if she were to wear one. My cuckold fantasies and just generally wanting to see her exposed were only in my mind and I never expected anything to come of it in reality. My gf must have remembered me talking about it though and internalized it…
On the night in question we went to see bands play at a local bar where a group of my friends were drinking. We got pretty wasted before we even left and when she got ready I didn’t think much about her outfit. She was wearing a black miniskirt with tights and a very low cut top, but she had a jacket on that hid her chest. We went to the bar and she was acting strange, more confident than usual while we caught up with friends. After a short while we decide to go smoke a joint and she invites one of my friends to come to the small bathroom in the courtyard of the bar, it is very crowded and not a super private place. I didn’t suspect anything at this point.
