sex move. While penetrating the vagina from behind, the penetrator must use his thumb to excavate the asshole. If the female being boned allows the thumb to stay in the asshole for an extended period of time, the penetrator must use his thumb as a "shoehorn" to ease his member inside the rectum. This way, the female will have no chance to retaliate while the switch is made
