Dear Miss Della,
I'm so proud that I reached such a personal best under your awesome wicked control (even if you didn't intended that I do the last 30

)!
150 edges in one week without cumming!
Thank you so much!
My balls feel so full and I'm so desperately longing for release!
I guess trying another 15 edges would drive me insane.
I need to cum!
I beg you, please, let me cum!!!
You said you want me to impress you. Hopefully this number will do a bit

I don't know f the following will do, but here is my proposal:
As you may have seen, I'm not only into T&D but also into bondage.
The preparation:
So I'd like to take two shoelaces, one to tie my up at the base of my cock and my balls. The second one to tie up my balls only with taking care to separate them, but keeping some length left to tie this end to the wrist of my stroking hand - long enough to stroke, but short enough that stroking to the head of my cock will result in tugging my balls.
To spice it up a bit I like to stand at the end of my bed my ankles spread and tied to opposite sides of the bed.
Ups, I nearly forgot to mention the metronome (
http://www.metronomeonline.com/) I need
The action:
Starting with applying a lot of lube to my cock to get it really slippery and setting the metronome to 40 (that's damn slow).
As 15 is our special number, I will do 15 strokes at this beat followed by five slow circles of palming this frustrated little head. Then increasing the beat one step and repeating the strokes and the palming. I will continue this for a total of 15 speed levels reaching finally 72 bpm.
Then I'll have to hold that speed for at least 150 strokes.
Btw: Needless to say that I deny myself not to cum even not to edge 'til this moment. In case I can't hold back, I have to ruin that orgasm.
In case everything goes well, I'll increase the speed for one step and do another 150 strokes. I'll repeat that until I cum!
Oh, I forgot to mention that fully cumming is only allowed during the last 30 strokes of these 150! Otherwise... hm, what do you think should I do? Ruin it or palming the head for 150 painful ticklish cycles?
Oh, now I'm so curious to hear you opinion!
Would this impress you, mistress?
Or would you like to 'optimize' this in your wonderful way, or even would you like to give me a total different order?
impatient regards
