"I'm tired of being fat, I want to lose weight but without commitment... I don't want to give up good food and I hate working out!", Luna complains, "help me Mr. Google!" So she discovers the existence of Hydro Colontherapy, but the prices are really prohibitive for her! "After all, all it takes is a shower hose and a bathtub, right? I can easily do this at home by myself!" The girl moves to the bathtub, where she grabs the shower hose and shoves it up her butt. The water begins to flow into her, passing her rectum all the way up into her colon. It goes in and out, in perfect balance, inflating and deflating Luna's belly, who is extremely amused and excited by the situation and describes to you minutely what she is feeling. "now I want to try to hold the water in a little longer!" she comments, causing her belly to inflate and leave it swollen for a while, then release it again. "it's already working, I feel like I'm going to lose so much weight and I can finally wear skimpy bikinis and crop tops!", she comments foolishly. Suddenly, the water stops coming out of her body. It comes in, with impetuous strength and reaches her stomach, but it doesn't come out! What's going on? Luna can't turn off the tap because she thinks that the continuous flow is the only thing that with the pressure can help her to expel the trapped water, but.. her belly starts to swell, more and more! It hurts so much! It's swelling more.. it's out of control!!! Suddenly, darkness, and a wet explosion fills the air.
