"Do it, edge yourself for me!, go ahead- Get as close as you can and then let go of your cock!. Don't dissapoint me again slave!.
(You edge yourself to the very brink of orgasm)
"So far so good, no accidents as far as I can see, good.. Ok, just calm yourself for a second and then use your non dominant hand and edge yourself twice in a row for me. But remember to behave yourself slave. I swear if you accidentally ruin your orgasm here with me you'll regret that dearly. I'm the only one who can order you to do that."
(You edge as you're told)
