ハンズフリーオーガズムのためのオーバーヘッド推定とballbusting

I've been estimming for an hour, and it's time to rachet up the intensity. I start out slapping the crap out of my dick and balls, and turning up the power on the electrodes.My cock starts twitching, so I whack it some more and play with zapping my nipples. It all leads to a happy ending. HFO.
