There are a few threads on here that talk about accidental creampies but I haven't come across any that looked at accidental female orgasms. If I hadn't seen this video I would have never believed it but it does happen.
Personally I find it hilarious, well this particular one is...I still can't find what 'caused' the orgasm tho because it seemed to have come out of nowhere.
Watch it and tell me what you think
