"Murr, it was a good idea to wear a bikini on top of it! It's getting so tight already, but I know it can soak up a lot more water. It's getting so mushy, so sloshy with its insides turning into a gel. What a lovely feeling! I just want to keep feeding it with the liquid and feel it growing more and more! Ooh, so heavy and big already! But it'll never get too big for me!"
This pussy is absolutely crazy about things that can grow, inflate and expand, be it a balloon, a soap bubble, a chewing gum or even... a diaper. She doesn't need them and can't even use them. But she doesn't need to for as long as she has a long water hose to stuck under the waistband and feed her diaper with water, feeling it growing between her legs.
