Don’t start immediately
When you are planning on a hand job, don’t start right away. First kiss and caress the rest of his body. When you take his pants of, don’t remove his underwear immediately. Get him longing for your hands on his naked body. Build up the tension. Caress his buttocks and thighs, letting your hand touch his penis accidentally now and then. Once you start touching his penis do it very lightly at first, touching the sensitive spots before you start jerking. Let him long for a firm grip. When you tease him this way he’ll really appreciate it once you start stroking his penis in a steady rhythm. Another way to tease him is to stimulate only the shaft and wait with the glans till he cannot stand it anymore.

Postpone his orgasm
A hand job is more fun if you postpone his orgasm. If he is almost ready to come, you no longer pay attention to his penis, but start caressing another body part. After a while you stimulate his penis again. This way he gets more and more horny, his orgasm being more intense than if you let him come right away.
