As usual Luna got up late and in the fridge she finds only a yogurt for breakfast. It seems to be a particular kind of yogurt, famous for its extremely powerful probiotics.. for sure the color is strange, but the taste is acceptable so the girl swallows it all in a few seconds. After a few moments, however, strange noisy cramps begin to pervade her abdomen. Maybe it's time for her daily toilet trip? Luna sits on the toilet but realizes that something is wrong: what she feels is a totally new and different pain.. she doesn't have to go to the toilet! She moves to the bed where she hopes to get some relief by lying down, but at that point her belly starts to be beaten by wild spasms, as if something is putting pressure from inside to.. get out? Luna is terrified, describing what she feels until the inexorable explosion.
