The sexual act, similar to the eiffel tower, but with two girls as well as the two guys. Both couples face each other while having sex from behind, standing up and bending the girls over. The girls can make the bridge by holding hands for support, or draw it back by letting go of each other. The guys can high five over the top for added effect.
Me and Rich were down in Fort Myers together and were banging these two girls on the beach drawbridge style, right under the pier.
