Men's beauty salons advertise themselves as non-sexual services, but many people have a grey area in their minds. What is it really like? We invite mature men's beauty salon girls, who are rumored to offer hidden services, to a room fitted with a small camera to find out what it's really like. The girls we invited are Ms. M, 34, and Ms. T, 40. Will they really let us do it when they beg you to let them? From the usual massage to tense negotiations, to a dramatic ending. The whole story has been secretly filmed and is published here. The work of these mature men's beauty salon girls is far from grey; it's pitch black. Please enjoy.
