First of all, it is just an idea. IO haven't tried it yet.
Second, sorry for any English mistake.
- A dildo (blue) in anus, firmly attached to a shaft (black).
- A shaft (black), tied to ankles.
- A rope (green) that binds both ankles and prevets the dildo to get out anus.
- Another rope (brown) that must be pulled by feet and triggers a release mechanism.
I can foresee that, if the person rise his or her feet, the dildo would slip out. So, I thought the shaft should run in some ring screws.
