Twin Twister

The act when twins each pick up a person from a different bar and take the girl or guy back to the same house without telling each other. Both twins use the same alias. After intercourse initiates, they must then meet at the bathroom and switch bedrooms. After they finish having intercourse, they swap back and the girls never find out.
