HUNTC-426 My caring sister-in-law becomes my nude model!? I joined the art club because I wanted to see a woman's naked body. But! Nude drawing time only comes once a year! When I found out the truth and was depressed, my sister-in-law actually became my nude model at her house. I was so excited watching her shyly take off her clothes! And then...

I joined the art club because I wanted to see naked women, but we only get to do nude drawing once a year. I want to see more real naked women! I was suffering in my room like an artist in a slump when my sister-in-law, who cares deeply for her younger brother, volunteered to be my nude model! I was incredibly excited as she shyly took off her clothes in front of me! I got a massive erection from my sister-in-law's artistic naked body! My creative urge was ignited, and as I began to paint, my sister-in-law was made to strike all sorts of embarrassing poses, and before I knew it, a sparkling, clear liquid was dripping from between her legs! After seeing this, I couldn't focus on drawing anymore! I sublimated my surging artistic spirit into a lecherous spirit and poured it all onto the canvas of my sister-in-law's pussy!
