PPPD-754 I was found out by a local classmate for working at an izakaya. It's Rinne and Yuuka.

To save money for my dream of studying abroad, I decided to work at an old man's pub a bit away from my hometown. By chance, a male classmate came to the shop and was found out. Rumors spread, and even my least favorite teacher from back then showed up… From being forced to do breast handjobs in the store, demands escalated to actual in-the-act ejaculation, and ultimately turned into a class reunion of in-the-act gangbangs by my classmates… 'Wow! These are the nipples of Rinne, famous for having the biggest tits in school!!'
