Doublegirthsquirt
A doublegirthsquirt is when a man ejaculates inside of a girl and at the same time a girl ejaculates and squirts out all of the cum, creating a doublegirthsquirt. It is the combination of both gender's liquids coming out of a vagina at the same time in one shot.
My friend told me he had the craziest doublegirthsquirt with some girl the other night! Can you believe that?
