Requesting Ideas for Hidden Public Bondage

[LoveBreastBondage]

I am an 18-yr-old girl looking for ideas on self-bondage under my clothes, specifically on my breast/nipples, during class (college). Thanks!

First make yourself a right crotch rope. Then tie your breasts up. Now your the crotch rope to your tits. Make it tight enough so the only it doesn't hurt is if you bend over a bit.

Bra one size too small and lined with coarse sandpaper, and modify the back strap so it can be locked with a padlock - better still two padlocks: one wih key and one with 4 digit combination.
