[ENGLISH-SUBTITLE] YUJ-019 My senior at work has a plain appearance but a strong sex drive and always invites me to have sex after work.

Kaoru, a senior at my part-time job, looked after me when I was drunk. However, I was so drunk I couldn't even walk properly, so worried about me, she let me stay at her house. When I woke up in the morning with a throbbing headache from a hangover, I found Kaoru in front of me, breathing heavily and defenseless...! When she woke up, I couldn't help but kiss her. I had no idea that Kaoru, who was rather plain and unassuming at work, would become so aggressive when it came to sex.
