Danse sous la douche, ouverture surprise en public

On typical sunday I went to the gym near my house, i do not often take bath there because is crowded and a small locker room. But at this day I felt a suddenly will to dance and mock in front of a mirror, and then I have noticed that mirror is in front of one of the shower, even tough with afraid to get caught i went down brave showering master as i usually am!
