As you pin him down, spread apart his legs and kiss him through his underwear. Kiss his inner thighs and work your way to his sweet spot, making sure to kiss a little longer where it’s most sensitive.
Lick him up and down, still through his clothing, until you can see his bulge twitching and bobbing in anticipation. Slow down your pace until he’s bucking his hips, raising himself to press against your tongue.
Only when he’s a crying, shaking mess of a man do you begin to undress him.
