Because fruit bats, it seems, have been doing it just as long as us. Very few animals engage in oral sex, but according to scientific research, fruit bats are all about blowies. During copulation the female fruit bat “lowers her head to lick the shaft or the base of the male’s penis but does not lick the glans penis which has already penetrated the vagina.” And the male bats love it so much that if the female bat gives them a little licky-licky during copulation, they’re likely to last longer.
