no teeth, lick and suck his balls, lick the sides of his sack, swirl your tongue around the head, use plenty of spit to keep it wet, suck it hard so that it makes a loud pop out of your mouth, slap it against your tongue, make sure to moan and make plenty of filthy sucking noises, suck him and jerk his shaft at the same time if he likes getting jerked, finally, stick your tongue out submissively and feel his warm semen splash on it, embrace his orgasm like it was your own, swallow his sperm like you're starving.
