Standing up Wanking

I've used oil , to get better slippage . I roll my dick around and massage my balls , because it gets me really hard and me very horny ,I love cupping my Balls just before I cum . I like to feel them throbbing When i ejaculate and standing I get a better orgasm , getting to the orgasm i have to push hard and when i cum , my legs tremble and shake as i shoot my load.
