I've noticed a lack in Undertum and Inflation stories, so here's a collection I will work on every once in awhile! From inflation to weight gain!

Edit: I'm probably going to focus all the tummy love towards male characters, I find that there are so many female stuffing/inflation fics that I want to give the bois some love too! That doesn't mean that females cant be feeders/inflators, but I want all the belly action to be centered around the male characters...
