Boku-tachi wa Mada Aoku

Komachi says she is going to show him how she masturbates. However, she is embarrassed to be seen with her fingers in her crotch, so she says she will only show him how she plays with her clitoris.
She is breathing heavily as she plays with her crotch with her slender fingers.
...No, it's more erotic than I expected....
I didn't know Komachi liked it that way too....
The first time he saw her, he was so excited!
