Accepting your Femininity
Well alright, let's talk about the male orgasm for a minute. This is something you will get used to causing, but not experiencing yourself.
The amount of cum a man shoots is based on a lot of things. How recently has he came? How much pleasure is he receiving? How many times have you brought him to edge before allowing him to explode?
As a sissy slut you'll be in control of most of these things. Whats that? You didn't think you were going to be a slut? How else do you expect to practice your skills? Soon you'll be going out to STRAIGHT bars and asking guys if you can suck them off in the bathroom. You'll deal with rejection like all sissys, but every few guys you'll get one who will say yes, you'll take him in back and *ahem* lighten his load.
The most important thing in getting a man to cum every last bit is the performance. Everything from seduction, to fourplay, to sex, to the final handy/blowy before his shoots. Thats what I'm going to have you practice, but first we need to sort a few things out.
