Karin Onuki is a petite, lolita-faced girl working at a certain shop. Though she looks youthful, her body is surprisingly mature. Busy with work and without a boyfriend, she relieves her daily stress on her own. It's been a while since her last sex, making her extremely sensitive. Unexpectedly, she squirts multiple times, and finishes off cleanly with an internal mouth cumshot. Her performance is perfectly erotic.
