Married teacher's silent, tenfold pleasure through dry sex instruction - Reiko Iwai IQQQ-38

I know that having inappropriate relationships with students is unbecoming of a teacher, but the more I feel the guilt, the more it burns within me, and I enjoy the thrill of not being discovered. Recently, however, these sexually charged students have made even more provocative demands, wanting to have sex even at school. Even when I scold them and tell them no, they won't stop. So Reiko can only silently endure the suffocating pain.
