A voluptuous woman with bound breasts, seemingly fallen from ropes - Himesaki Hana DASS-235

Homeroom teacher Hosoda is a sadistic man with a craving for bondage. Every night, he fantasizes about tying up his student, Himeaki. One day, he calls her to his home for career advice and places a rope where she can see it. She keeps staring at it. Seeing her reaction, Hosoda is convinced she has a "bondage desire" and uses his words to lead her into bondage. At first, she doesn't like it, but on the other hand, her vagina becomes wet. From then on, through Hosoda's "punishment," her perversion accelerates further.
