Demanding Mistress
Well then, how long was that, slut? If you took more than a minute I'm very disappointed in you slut, you're not improving your chances to cum at all. Smack your balls, HARD! 1 smack to each ball for every 5 seconds longer you took than a minute. Look up at my beautiful ass as you punish yourself, in fact, even if you did get back on time, give yourself five hard smacks to each ball, and thank your Mistress for giving you her attention.
Light that candle slave, put it in a safe place, I just wanted to create a little atmosphere, hehe. Oh, and lay that towel underneath you, we can't have you making a mess now can we?
Now stroke for me slave, get that cock nice and hard, you may use your lube. Edge for me slut, get as close as you can to the edge for your Mistress.
Now STOP! Hands off until I say so, show your respect for your Mistress.
