Here are two scenes that can be used with figging:

A old wood kitchen chair is fitted with a long dildo or plug. Something that has lots of ridges or is imposing in length. The sub kneels in front of the chair with wrists tied to the back.

The Dom then makes a ritual of wiping the dildo with alcohol (bringing memories of doctors visits), putting on rubber gloves, preparing the fig and inserting it.

After a few minutes of silence the sub is lectured. Then a condom is put on the plug and then liberally coated with nice, cool lube.

Painful, burning rectum and large, cool dildo...

The Dom can then leave for a while if he thinks the sub will scratch their own itch while he is gone. Or he can ignore the sub waiting for the pleas and begging to be sufficient to let the sub impale them selves.

BJ Incentive:

Sub is put in kneeling position and fig is inserted. After a few minutes for the pain to build the dom puts on 2 condoms and informs the sub he/she will be sodomized only after working hard enough with their mouth. After enough effort, one condom is removed, lube applied and the fig is removed and replaced with a dildo or cock.
