You are such a wimp. I knew you'd give in, but I didn't think capturing you would be quite so easy!
Let's get a few things straight. You only cum when I say. That's right. You have no control over when I might let you shoot your own cum. You can stroke that raging erection of your as much as you want, but you DO NOT have my permission to cum.
Wimps like you keep their nasty sperm inside, where I say it belongs.
Me and my lovers, of course, are allowed to cum as much as we want! You'll soon find that my pussy is nearly always filled with cum from my lovers. If you're really obedient I might let you watch when we fuck! I can see the way your penis is throbbing, that you'd really enjoy watching a real man fuck me!
