That JAV

My name is Rei Hanamiya, and I have been assigned to this private ● school as a new teacher. After failing a number of employment exams, I found an opening for a temporary position at this school on a dark web site. The hours were very short, but the pay was double the normal salary...but there was a secret to it. The special contract for the temporary position was that I had to sign a mistress contract with the principal and perform sexual services for her every night. However, a certain adulterous sado-scholar got wind of this, and I ended up being played by both sides.
