MIAA-184 I was planning to secretly meet my boyfriend during the school trip at night, but I got caught by my annoying homeroom teacher and got lectured all night long... Akae Negao.

My first experience with internal ejaculation, my first vaginal orgasm, all taken away by the teacher I hate the most, and made to cum repeatedly until morning... I wanted to do it with the boyfriend I love... A couple trying to meet secretly (sex) on a school trip night. Despite being in a school that prohibits dating, the two young people expected to be able to stay together at night with the person they liked. But they were caught by a power-harassing teacher. Akari, threatened with expulsion, was subjected to a lecture through super athletic-style pistoning by a Showa-era sex machine...
