This video is a compilation of works submitted to the SM magazine "Mania Club." [Editorial commentary] Setsuko is a former female teacher at a public school. Her young master, Takuya (not his real name), who is nine years younger than her, is her former student. It all started when she met Takuya at a class reunion and exchanged email addresses with him. In her conversation with Takuya, Setsuko learns that he has had a crush on her since their school days, and that those feelings haven't changed, and Kokoro is shaken. Since giving birth to her child, Setsuko and her husband have been sexless. Setsuko is about to cross the line with her student Takuya. He tells her, "If you use the back hole, it won't be cheating," and she accepts his words. That was the beginning of everything. Having discovered the pleasure of anal sex, Setsuko's body begins to accept Takuya's sadistic desires with her whole body, and she begins to desire them herself. Group play, rental slave, enema, bondage, and an anus that is expanded to the point of swallowing a vibrator... With the escalating training, she has now been transformed into a complete slave. ■Scene 1 A collaboration of a full-head mask, bizarre costume, and a mature woman. Tongue clothespins, nipple chains, anal vibrator torture, anal electric massager insertion, the torture of the anus escalates while she is deprived of vision. ■Scene 2 A glass cup is inserted into her anus. Her anus swallows it easily. Her rectum is exposed through the glass. The deeper it is inserted, the thicker the diameter becomes, so her sensitivity increases. ■Scene 3 Intense anal fisting. Setsuko's sphincter tightens her wrist like a vice. ■Scene 4 Before starting the anal training in earnest, the shower is poured directly into her anus. Her anus is poked with her fingers, and all the remaining excrement is made to come out. ■Scene 5 She is made to drink every drop of urine as a reward. ■Scene 6 She is so desperate for a vibrator in her anus that she presses her hips against it. She is forced to walk on all fours while still penetrated. She licks her legs as a sign of loyalty while moaning in pain. The vibrations of the electric massager bring her to her limits. ■Scene 7 The fist wriggling inside her anus brings her to orgasm again and again. ■Scene 8 The vibrations of the electric massager that she swallows build up inside her body and eventually come together as a huge climax. Her labia throbs red. ■Scene 9 A sex slave who welcomes Uichi and another sadistic man to continuous anal rape and full-scale dildo expansion. A female teacher whose masochistic desire has blossomed in the pleasure of her genitals and anus, drowns in a bottomless swamp of abnormal love. ■Scene 10 She straddles the toilet seat and is subjected to anal vibrator torture and hard fisting. Her orgasmic face is exposed to the intense anal torture.
