Dominating your Man: An Introduction
When you feel like you're getting close, ask him if he wants to try to please you again. By this point, saying no shouldn't even be an option in his mind. With the vibrator, straddle his face again, but this time bury his face in your ass and instruct him to eat it. Grind on the vibrator, play with the clothespins on his body, enjoy the feeling of his tongue on your asshole. Periodically ask him if he likes how your ass tastes, if he wants to stick his tongue in it, how good it would feel to stick his cock in it, etc. This gives him a chance to take his breath before sitting on his face again.
Keep going until you're on the edge of an orgasm. Pull all of the clothespins off using the string like a rip chord as you go over the edge. Take however long you need to recover.
