Forced farting using chastity belt and electric butt plug

I have a chastity belt and an electric butt plug. The belt is leather and a butt plug holder is used to hold the electric butt plug on the strap.

One day I discovered if I pull the plug holder up, strap it in really tight and put my butt up in the air their is enough space for my anus to gape a little. The shocks make the muscles move in and out which make my butt gulp air. I can feel the air moving in and out of my butt and if I bare down my butt produces a really loud fart! Like comically loud. I can fart over and over in this position. I did it for 5 minutes strait today. I'm not really into farting but I do like humiliation and being forced to fart loudly is pretty humiliating. I'm astounded that I can reproduce this effect. Does anyone have any thoughts?
