I wake up still in the closet

I awoke thirty hours later in a daze. I snapped out of it and tried to remembered what I was doing. I recalled whacking off to Yumi masturbating and I was kinda ashamed of myself for doing such a thing. But then at that moment I heard the ripping of a electric guitar and Yumi screaming.

I then went back to looking through the keyhole of the closet at was amazed of what I saw. Yumi was still naked but 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.
