Well i myself never gave any guys a hand job so i wouldn't know from experience but as a basic starting point, however,firmly, but gently, wrap your fingers around his member and move your fist up and down his shaft in a slow, steady motion.
Variety is one of the key ingredients to a moan-worthy hand job, so mix up your speed and pressure as his arousal grows. Be sensitive to the way he responds, and you'll soon find the confidence to try out different techniques. Ultimately, the only limit is your imagination, so here are a few ideas to get you thinking;
The Ring of Pleasure
Instead of using your hand around his shaft, form a donut ring with your thumb and forefinger and get a rhythm going just under the glans at the top of his penis.
The Comb Over
On every other 'upswing' or so, take your thumb and rub it over the top of his penis head before bringing your hand down again.
The Pastry Worm
andwich his penis between the flat of both hands, then roll one hand forward and the other back. Repeat the motion back and forth as if you were playing with pastry, and not trying to light a fire with sticks.
