Somehow, I'm captivated, sitting on a chair, looking at the gentle and cute Sumire-chan. Suddenly, she gazes lovingly at a finger that appears, and then directly into her mouth. She sucks on it seductively, and then begins to stroke her own body with that finger. Using an unknown person's finger to masturbate is so exciting to watch, the person doing it must be quite something. Boldly spreading her legs, she next directs that finger towards her vagina. She presses it vigorously, imagining herself being toyed with by someone.
