During a visit to the family grave, I returned to my hometown and unexpectedly met my teacher from my student days. Conversation flowed, and we ended up going to a bar to drink. Carried away by the moment, we spent the night together... However, it turned out that the teacher had a liking for bondage... For the first time, I experienced being bound and awakened to an unknown pleasure. The pleasure of the ropes was unforgettable, and Mei tried self-bondage masturbation but was not satisfied... While her husband was on a business trip, she embarked on a two-day, one-night affair and training trip with the teacher.
