Assistance Wrapping Up a Concept

I’m relatively new to SB but have dabbled a bit. I’m working on assembling a scene with the gear I own: an outdoor structure without electricity, some hooks and abots, rope, leather cuffing straps, a chastity device, and an Aneros. My aim is to set up something where escape is quick if needed (though not desired), perhaps using clamps attached to me and ropes securing my cuffs above my head? I’d like to be secured in place and see if I can reach orgasm without hand assistance while locked, relying solely on prostate stimulation. (I’ve pulled this off before) I just need a bit of guidance tying everything together. It doesn’t strictly have to take place outdoors; I’m open to various suggestions. What I really want to avoid is being stuck in an ice-lock scenario where breaking free becomes difficult.
