Tied Up Fellatio

I like giving guys head, but only when I'm fully in control, I don't like being pushed or groped, and hate being face fucked in any position. So my solution is: you get a blowjob from me only if you are naked and tied up. Then I can do it at my own pace, there's nothing you can do about it, I decide when to start and stop and how to do it. Long after you climax I can untie you.

And no, you can't tie me up, doesn't work in reverse.
