There's no better way to differentiate between the two men in your life than to let one cum inside you and make the other clean up the mess.

The superior man is the one that gets to enjoy the pleasure of fucking you. He gets to enjoy your warm, wet, tight pussy. He gets to kiss you. He gets to play with your tits as he pounds your pussy. He gets to make you cum with his big cock. He gets to cum inside you.

The sexually inferior man - your cuckold - gets to crawl between your legs and lick a hot load of cum from your cunt. He can cum if you give him permission, but unlike your bull, he must first get that permission from you. He's not entitled to that pleasure. Not in the slightest.

Do this just one and your cuckold will understand that he's the sexually inferior man. He'll understand his place. Chances are good he'll feel a newfound love for you, too, as he gets off on the humiliation of being put in his place.
