That's it, on your knees, clutching the sheets, fucking yourself. Take it for me. Look in the mirror and see my beautiful body. Worship it. Fuck yourself for it. Moan and beg for a throbbing cock in your hole, just so you can continue to serve it.
Look at yourself. Watch yourself being fucked. Does it turn you on, how deep down the rabbit hole you've gone? You're neither a man nor a woman, now, just a hole for your mistresses amusement. This is what sex is to you now - on your knees, locked in heels and chastity, fucking your ass without even the hope of coming.
And it feels so nice, doesn't it? It feels so nice to be under my control. It feels so nice to be frustrated, and humiliated. It feels so nice to fuck yourself into a frenzy and be all pent up with desire.
Enjoy it for as long as you like, and when you're done, thank me.
