I'm a lover of teasing handjob.

To me there's something sexy in the art of an edging handjob. Knowing just when your partner is on the edge and knowing just how to slow it down, from firm strokes with his cock in your oiled hand to light strokes with your fingertips.
Teasing the tip with your tongue and stroking his balls. Running a hand over his thighs and stomach. All keeping him on the edge, not letting him cum until you're ready for the sticky reward. Feeling the power and control knowing that his orgasm belongs to you.

The first time I did this for my husband I kept it going for nearly an hour. The last ten minutes he was writhing and begging me to let him cum. When I finally did I licked the head of his cock as he erupted with the most powerful orgasm he'd ever had (his words) taking him in my mouth letting his cum overflow, and then teasing his sensitive head with my tongue as I cleaned him up.
