MVSD-654 - Despite having a girlfriend next to me, a nude model, older sister Maki Izumi, shows me that place and smiles at me during drawing sessions.

I'm dating "Megumi" from the same art club at university. Starting next month, a female model named "Ms. Maki" will come once a week, and nude drawing classes will begin… I don't know any other naked bodies besides hers. She was beautiful and had a great figure, unlike her. Ms. Maki kept smiling at me a lot during the drawing sessions… The mature charm that confuses me, who only knows me… The nude model sister's hidden face was a mysterious exhibitionist who loves herbivorous men. One day, I was called to the art room at night under the pretext of individual drawing… and she spread her male genitalia dripping and tempted me. Ms. Maki suddenly kissed me on my blushing face. "Making the penis so erect… cute…" I couldn't control myself with the overflowing pheromones and seductive nudity…
