After many years I now discover I can cum 'hands free'. Having a morning hard on I closed my eyes and imagined my partner giving me a blow job. A few minutes later with a bit of stretching I shot over the sheets. A few days later I told her what happened. She wanted to watch so I did it in front of her. I now find I can do it standing up and in most positions. All guys experience wet dreams at night but not this. Just goes to show, you keep on learning new tricks!
