GVG-378 Underground Anal Slave for Sexual Treatment II

Located in the basement of a multi-tenant building somewhere in Tokyo is an underground anal slave training center for sexual services. Women with special needs are gathered there and trained to become anal slaves tailored to the needs of the customers. The training begins with anal masturbation, anal expansion, and public enemas, and gradually becomes more and more rigorous, adapting to the needs of the customers and including special anal play such as double penetration, bondage, and candle play.
