I witnessed my girlfriend used by two strangers
During a night out in town, I had noticed a couple of guys watching my girlfriend, I think that she had noticed too and kept glancing across at them. At some point she had gone to the ladies room to freshen up, as she had been gone for quite some time, I decided to check she was OK. There was a fire door by the restrooms leading to the back of the building and I could hear noises, so checked outside. The two men had my petite girlfriend pinned against the wall, they had her dress pulled down to her waist sucking her tits as they ran their hands over her pussy and she was twitching and moaning loving the attention. I watched as one guy dropped his pants and the other spread her legs and as the guy fucked her hard against the wall, the other guy sucked her ample tits, the scene was so hot, I just watched and stoked my cock until I had seen them both cum on her. I slipped back inside and returned to our table. I never told her what I saw, but think about it all the time.
