You're about ready to pop

So you're lying there, a very attractive girl is on her knees sucking on your cock with gusto, her annoying companion is out of sight and mind, life is decent right now. You can feel a familiar pressure starting to build up in your balls. After all, you were watching porn before the women arrived and the whole experience has been pretty damn erotic. Straight out of a porno even, if you do think so yourself.

Now Sister Holly is bobbing her head up and down and your balls are bubbling. You try to ignore the periodic scrape of the teeth and focus on her magnificent rack. Her eyes are either closed or down, she can't bring herself to look at you. You can feel yourself getting ready to cum. Do you hold back? Do you try to push this to another level? Do you let Sister Holly know you're about to shoot a load down her throat? Are you about to treat Sister Holly the same way Jackson Pollack treated a canvas?

Too many options!
