She 'plays' with her guitar

Yumi then had her guitar and amp set up on the bed. Her pussy was resting on the side of the guitar which I believe was a v-shaped one. I didn't know what it was called but I don't know much about rock music equipment. She was then playing some rips on the guitar shrieking in delight from the vibrations. Her juices were dripping all over it.

I found this kinda clever making a vibrator out of her own musical tools.
