Innocent-looking picture book writer Machi-chan. Because she usually masturbates while looking at erotic manga and likes vibrators, when she does vibrator insertion exposure, she cries hysterically many times because it feels so good. She has an exposure orgasm while suppressing her crying voice. The highlight is the in-car exposure vibrator masturbation on the way to the hotel (she's cumming with her eyes rolled back). The completely self-made vibrator masturbation kamishibai is also a must-see!
