The gecko is a sexual act between two people or more (if that’s what your into) where the thumb is inserted into the anus of the other player and that person is made to climb up a wall in the motion of the cold blooded reptile known as a gecko.
Hey guys, the coolest thing happened! Me and my dog did the gecko last night!!! He claimed sooo far up the wall!
