I did, actually - some years ago. A pretty Pole with an over active thyroid so she was "full" and ready to go - most of the time. She also preferred A to vaginal intercourse claiming she could "come in her arse." For nearly a year she "fed" me every day and I never succumbed to any infection or disease. She liked to wash it down with her pee. She was also the most fantastic domina and while sitting/shitting on my face would be whipping me or stubbing a cigarette out on my arm. PERFECTION.
