First and foremost have a safe word. This must be some obscure word not used in normal conversation. The purpose is so that there is an "out" should he want it. NEVER EVER violate the safe word. When he says it then whatever you are or have been doing stops immediately. If he says "don't" or "stop" or anything else, you can probably choose to ignore what is said.

Use a feather to tickle his skin and send shivers up his spine.

Have your way with his penis, possibly over and over and over again.
Do things to it that you know he likes. You can build him up repeatedly
all within a few minutes, or, you can keep him wanting more by spacing
your caresses out over time.

You can shackle him to the bedposts or you can sit him in a straightback chair. If the latter, give him a lap dance..............

These are just some ideas from me. Who else has some tantalizing suggestions?
