Women are inherently jealous creatures. It is bad enough that a woman must share her man's cock, but to insert him 
into some other slut's sopping wet pussy is just about the most humbling thing a woman can be asked to do.

Here’s why. Because there will come a time where she becomes so desperate to cum that she’ll do anything to be 
allowed to cum. The amount of depraved and disgusting things she will do in order to earn an orgasm from you will be 
incredible. So deny her until she has no shame left in her body and make sure she proves it.
