Last night I did it:
Removed my clothes except for the leather ankle and wrist cuffs.
Tied in spread eagle with feet to the spreader bar with 2 ratchets so I could spread my legs out towards the spreader bar which is tied to the cabinet leg. So that I can not make any movement in the spread legs.
Below me a lounger cushion with a number of folded towels above to catch everything.
Close to the body, the elastic bands with the contacts above and below the penis connect to the B channel of the DG-lab.
Above these bands the
Masturbator Wand Attachment with the European wand vibrator at minimum strength in a position against the frenulum.
Lovense Gemini nipple clamps on position 4: constant pulling on the nipples.
Time padlocks at 2 hours duration for both left and right hand cuffs; the one on the left on a ring, the one on the right on zipties that I can open again as a backup (if both time padlocks should fail).
Then "Stay alive" app started so my cell phone doesn't go down.
Then xtoys.app with pattern Moan softly~ by Leetthief (4m05s) and the
5 steps program from HitchhikerNL and KinkInSpace, this time with the following changed settings (the other settings were the same as in the link):
Maximum strength on channel B at 160
Initial delay 120 sec (to get ready in bondage and to take a 2 minute break for the next rounds

)
phase 2 delay 30 sec
phase 3 delay 60 sec
phase 4 at max 245 sec (so to have all "Moan's streak softly~" program running during maximum strength)
end tour set at 115 minutes (at least 2 rounds, the first round focused on not having an orgasm, the 2nd round on having the orgasm as late as possible to have as little torture as possible - the latter of course failed

)
Pull the 2 ratchets for stretching and spreading the legs;
then left cuff with ratchet connected to the left time padlock;
homemade blindfold on so that everything was pitch black;
right cuff connected to the right time padlock;
tested if I can get to the zip ties (my only way out if something happens)
and then pull the ratchet of the left hand with the right hand.
Only the nipples hurt too much after the orgasm, but that was quickly forgotten when the penis also got its strong turn on.
