"Ok rule 3. You will never cum without my permission. Never. And while we are on that subject I want you to speed up your stroking."
"You begin to move your hand back and forward faster and faster."
"Have you ever heard of edging josh?"
"Yes, mistress. It's where you pleasure yourself right up to you're about to orgasm and then stop straight away."
"Oh, you naughty boy! I can't wait to try it with you. keep going until you are at the edge of orgasm and then take your hands off."
You picked up the pace until you were jerking very fast, in almost no time you felt the pleasure building to a crescendo and you threw your hands away, it wasn't as close as you could have got but you didn't want to screw up.
"Hahaha look at your little man! awwww so frustrated, he's twitching up and down. I love it!"
