Free stroking:
Okay, I can understand. You've been in chastity a bit and you can't wait to touch that dick. Well, go ahead then. You got 15 minutes. I'll make myself some tea. No cumming though! (don't read the next part, click continue now, then start a 15 minute timer)
Guidance:
(she smiles)
I was hoping you would say that!
(quickly, she sets the metronome to 20 BPM)
You're gonna stroke with a full tight fist to this beat. But there's a twist!
The first beat you're not gonna stroke at all. Just hold your cock.
The second beat you're gonna stroke once. Just do it in one quick motion and pause for the rest of the time.
The next beat is one stroke more, so two strokes and so on.
When you finished the ten strokes, you start again at 0.
Do not edge though! Should you come close to an edge, stop before the edge and do a relaxation round: It again starts at 0, but goes to 3 and down to 0 again. After that round, procede normally until 10 strokes again.
(she starts a timer for 15 minutes)
I think this will be a good system to make you get in as many strokes as possible, right?
I hope you'll like it!
