My girlfriend's older sister, Ayaka, a technical instructor for [Ejaculation Courses for Women], was suddenly asked to become a male model, and I was played with my blindfolded dick with amazing techniques and I failed and ejaculated multiple times...!

Her older sister, Ayaka, was surrounded by veil, and her job was to be an AV actress and a technical instructor for the sex industry! Then I came to help with my work, but I ended up not being able to play the male model, so I ended up having to take on the role of a substitute! Covered by the sheet, I only stick out my dick, and I couldn't help but ejaculate so hard by Ayaka's amazing techniques! Furthermore, the students also ejaculate and are moaning when their dicks are played with! Even though it was a lecture, I had to ejaculate prematurely, which was a failure... #Chapter P
