Make the most of every opportunity!

Don’t miss an opportunity to edge him, even if it’s just idly like this while doing something else.
More edges = hornier = better
Just make it second nature to simply tell him ‘get your cock out’. Even when you’re not in the mood, try it. Once you have your hand wrapped around his cock and hear his little frustrated horny moans you will be happy you did.

The movement she’s doing here is basically perfect. If he’s horny then the precum he produces will be enough to just keep that bit lubed indefinitely. If you run dry just give one stroke up his cock and more will seep out.

Leave him hanging…
It’s really hot to just stop sometimes, as though you’ve forgotten, leaving him there getting desperate for even the gentle touches. A cock ring makes this even more fun as he’ll stay harder longer and ache for more.

If you’re in the mood, wait till he asks for more, then say ‘if you ask again you’re going back in your cage’ – trust me, so hot. Being ignored isn’t hot, but knowing you’re doing it deliberately, amazing!

If he goes limp, tease him, ‘maybe he should just be locked up again’ (watch him get hard at that lol)

Personally I like playing with his flaccid cock too, if you’ve edged him so he’s already really sensitive, or he’s been caged a while, slow, lubed strokes and finger play that isn’t enough to get him hard will drive him absolutely crazy.

Make him do it!
And if you get bored, or really don’t want to, tell HIM to!

‘Edge your cock for me’

Or make it more productive than that:

‘Edge for me while you find me some hot tumblr posts’
or even more specific
‘Edge for me while you find me some big cocks’ 
Or whatever you’re in the mood for, sloppy blowjobs, romantic pics, mean bitches, ruined orgasms, cum shots, etc – and then you look at them while he goes down on you!

Or you can go directly to that, just have him go down on you, while he edges himself. Watch a movie, read a book, or browse Tumblr while he does. If he’s getting too excited, or just to mess with him, get him to stop sometimes and just focus on you. Then tell him to stroke it again. 

Try a dry, cleaned out condom on him to see how much precum he can produce!

Or add some variety, surprise him by throwing him dildo and some lube, he’ll think it’s for you, and sure you could do that, but even hotter to say ‘it’s for you, fuck your arse while you lick me’ (and even add ‘if you can cum from just that I’ll let you’)
