Here's a simple one.
Put your vibe under your clothes on your clit and go to your college central area/courtyard/quad or the equivalent and have an orgasm
Here's a complicated one.
You are going to go for a walk or jog around where you live. Wear some light colored spandex shorts and a white t-shirt without a bra (sports bra if that is to public) Put your bullet vibe in and set it to a medium/high setting. Take a bottle of water with you. If you feel yourself edging, take a drink of water but you are only allowed to waterfall it (pour it in your mouth not actually touch it with your lips) You can't stop walking/jogging. If you do go over the edge, pour whats left of the bottle over your head. Try to make your walk/jog at least a mile.
