The girl does not fall into pleasure

The story of the girls who were suddenly slaves one day, even though they were ordinary everyday life. Service and training days ... The limbs are shackles, the collar is fitted, the nipples are passed through the piercings, and the other is restrained and managed by a naked and narrow cage.
