Machi-chan, a seemingly innocent picture book author. She usually masturbates while looking at erotic manga and loves vibrators, so when she inserts a vibrator and exposes herself, it feels so good that she cries repeatedly. She orgasms while exposing herself and trying to hold back her tears. A highlight is her vibrator masturbation in the car on the way to the hotel (she's orgasming with her eyes rolling back). Her completely self-made vibrator masturbation picture story is also a must-see! (Partially modified from the original product number SUN-043...)
