Sheer Tease (a classic)

Sheer Tease (a classic) by Ford

You looked like you were getting close there... I like pushing you to the edge like that... so give me three more sets. But this time, there's a twist... literally. On the slow sets, I want you to twist that hand back and forth around your shaft on the upstrokes, all the way up to the head, at least three good twists... and then slide down hard on the downstroke... three twists back and forth, slowly up, and then one good hard yank down.

Do that 20 times, and then give 20 good fast strokes, then count to ten and repeat twice more. See if you can do that without stopping, but stop for a minute if you feel like you're going to come.
