Well, I am in a similar situation. Although in general, I prefer cyber to remote control. Also, I find that I can be quite spontaneous and rarely get stuck on what to do.

Here are some random ideas -

get him to kneel (at least long enough to make his knees sore) and lightly pinch himself all over.

Get him to bring himself colse to cumming, then have a cold shower, then go for a run, wait a bit, then repeat - this should tire him out.

No pillow or sleep on the floor for that night.

Dance and sing naked.

Get him to write lines (with pen and paper).
For example - "I will not have an orgasm without permission" X 50.

Get him to write a 500 word document.

Have him miss watching his favourite TV show/radio programme or some other habit he enjoys (no dessert?).

I don't know how useful any of the above ideas will be to you (considering I made most of them up on the spot) - but I hope they are of some help.
