It's been a little while since I allowed you to actually cum for me, even though I did give you permission to jerk off! Even if I didn't lock your cock in chastity, you know that being in mental chastity is much more powerful and efficient, as you love being mind fucked by me! And after all, you wouldn't want to disappoint your Goddess by doing something you know she didn't give you permission to! Well, today I woke up feeling generous, and I decided that I'm going to allow you to have an orgasm for me! That doesn't mean, though, that I'm going to let you cum just like that, without putting your obedience to test, of course! You're going to sacrifice for my pleasure, as you always do, by ruining your orgasm for me and then eating your own cum in the end! Oh, and there will be a little challenge you might have to pass if you don't want me to take your permission to jerk off away altogether! Yep, I might just not let you finish, even with a ruined orgasm, if you don't have enough self-control. What will the test be? Well, go ahead and find out, little one!
