This is a technique that came to me a few days ago. It's so very simple, yet so very effective.
Get your man lying in a position that he can easily assume, but that becomes uncomfortable over time. The one I used was lying on his back, with his legs raised and his his feet together, about a foot off the bed.
Anyone who's ever tried holding their feet up like that will probably know that after a while, your legs become very tired. So you tell him that you'll play with his cock, but only if he keeps his feet up. The second they drop, you stop playing.
At first, that'll be no problem. But after a few minutes, especially with the feeling of you teasing him and the pressure to keep his feet up, his legs will start to hurt pretty bad, and it's only a matter of time before he can't keep them up any more and he has to give in.
"Aw, sorry honey, you lose... Better luck next time, hehe."
