Finding a Back Massager

I was so horny always keeping an eye out for new ways to masturbate. One day at my friends, looking for towels, I found a back massager. I moved it so I could find it when I wanted to use it. My chance came a few days later. I had an entire evening till morning to go at it. I locked myself in a room upstairs for privacy. It had three speed settings. A bit over zealous I turned it on high. It vibrated my cock so vigorously I could barely handle it. I wanted to make it last and lowered it to the lowest setting. I sat naked laid out on the couch. I squirmed as I pressed up against myself. This went on for around 45 minutes. I then turned it up a notch making it impossible to sit still. I reached a strong orgasm that flew out from my vibrating cock. I ejaculated three or four more times through the night.
