What ever will we do? You want a taste of my cum so badly, but you're not worthy enough to lick my asshole clean. However, to show I'm not all cruel I want you to rub yourself until you have a little bit of white cum on your cock, not just pre-cum, but a little bit of real cum. Now take that cum up with your finger and rub it around your lips.
There's no way a woman's going to let you down there and even if she did you'd never be able to make her cum. You're own man jiz is the closest you're ever going to cum to getting real cum on your lips.
