This girl is my girlfriend, Shiraki Lisa. She has excellent grades and is the student council president. It's been a year since we've been dating, but he still doesn't let me have sex because he's super serious, and I made a promise that I won't have sex until I'm old enough to take responsibility for each other. But it's true that H should be done when you're an adult. I want to spend more important time with Lisa that I can only experience now. One day when she started to think so, on her school trip, Lisa was cuckolded by unknown college students.
