My [33m] girlfriend [33f] disappeared today and fucked a stranger in front of his wife [MFF]

My girlfriend (a chubby/fat girl with brown hair to her shoulders, DD tits and a big ass) and I are long distance at the moment. I love her very much. Because of our distance and because it will be a while until we are together, we have an open relationship. Everything goes fine. We have rules; each other has to know about every event and be checked in with after, play safe, nothing with anyone else that we don’t do with each other, basic stuff. We haven’t had any problems.

Generally, my girlfriend is shy and awkward. She does not take advantage of being open that much. She might occasionally flirt or go on a date here and there, but she has only been with a few men her whole life. She has never really been adventurous in any way.

Today we were having some fun. Internet sucks where she is so she went to gas station to use 4g and video chat with me. We were talking and eventually I flashed her my dick and started masturbating. She was obviously very horny today, because she joined me. We had fun.
