I've been starting to fill my gym shorts and sports bra with the help of people on Reddit and I thought I'd let you lot join in to!

All you need to do is comment below where you want me to put a cup of gunge inside my clothes and give me an exercise to complete. Once someone else has commented you can comment again!

Lets fill me up!
