I've been playing with a sub who loves orgasm control. Most of her fantasies include an element of being edged but denied an orgasm until she's practically begging to be allowed to cum. We've played with mutual masturbation a bit and I'd really like to incorporate orgasm control into our play but I'm struggling to work out the best way to do it.

Most of the time we're limited to sexting which causes a few issues. I want to either roleplay a fantasy scenario with her while she masturbates or give her instructions on how to touch herself, but without seeing or hearing her its impossible for me to know how close she is. I want to instruct her to stop as she's getting close and only let her cum when I think she's earned it.

The only way I can think of it working is if she keeps me updated on how close she is, perhaps sending me a number between 1-10 to indicate closeness every few minutes, but I think that might take her out of the moment too much.

I want to be able to guide her and control her actions while giving her something hot to think about, but doing this while we are both texting seems like a bit too much to focus on.

I'd love to hear if anyone has done anything like this successfully and how you made it work, or any random thoughts, ideas or suggestions around edging play over long distance.
