This video is a compilation of a large number of videos sent to the editorial department of an SM magazine. The two being trained are a slender female college student named Yayoi and a trained masochistic woman named K-ko. Yayoi is a beautiful female college student who still has a youthful air about her, and has always been interested in SM play and yearning for it since her childhood experiences. Before entering college, she signed a slave contract with a man she met, and was trained as a slave, and is now an anal rental livestock that is also being trained by another man. K-ko has been kept as a livestock for over a decade since she was a female college student, and is now a livestock female specialized in milking men's semen. This is a valuable record of the double training of a beautiful female college student who blooms in masochism in pain and shame, and a trained obedient sex slave who is specialized in satisfying men's desires and milking them, with the two of them forced into lesbian sex, forced cunnilingus with semen wiped from the pussy, double dildo binding, anal orgasm, neglect, double semen drinking, continuous anal hook torture, semen sharing kiss, 4P orgy, anal sex, bondage, whipping, anal long dildo insertion, sex slave sex instruction, etc. This work contains training videos carefully selected from a vast amount of play records, so please take a look. [Before purchasing] This work is a play video posted by an amateur SM enthusiast. There is no so-called AV-like acting or direction, and no story. It is a vivid and lewd video record.
