r/OneBarPrison

I have a scene planned with two submissive women (one cis and the other trans, non-op) using two identical vertically (90º from floor) aligned Hismith adjustable fucking machines with extension bars to ensure they reach the correct orifices.

Logistically, both subs are 5’7” and their crotch height is at 31” and 30” from the floor respectively. I have access to hard points above and both will be nude except for their collars.

I was planning on having them facing each other, with chest to chest, with their collars locked together with carabiners. A basic chest harness a hard point above, hands tied behind the back. Then tying the two of them together. Legs will be cuffed to the stabilizing arms of the fucking machine to keep them roughly shoulder width apart.

The actual insertables will be silicone, which I think is an important note since one submissive will have the prison installed vaginally and the other anally.

What other factors should I be considering and addressing? Anything from a safety standpoint that I need to factor in?

(This scene will be in a public dungeon but I’ll be working with the DMs to ensure at least some photos can be taken, hopefully including some I can share here if my bottoms consent.)
