Here is start of my experience fist myself standing up. I become really rough, wild, even had orgasm standing up in the end, I came with my fist inside!!!! It was wild, wonderful! I start from oiling my body near mirror - you see my ass and my face and tits at same time, I see my body reflection in the mirror, feel oil cover my body, become excited, horny, I like my nipples - they hard, do play with them, spank my boobies, spank harder and it blows my head off!!
