tri-beza gag
First performed by Theodore Beza in Burgundy, France, and made popular in Tribeca, New York, the tri-beza gag is a sexual act typically involving three people. In the traditional form the act consists of 3 people performing and receiving oral sex and simultaneously reaching climax together while gagging on each other's penis.
Mark invited 6 of his friends over for wine in hopes of ending the night with a double tri-beza gag.
