Trampling and Golden Showers

My is I would love to have a mistress trample me underfoot for around a solid hour. During which time she alternates between high heels and barefoot. I would love to have foot worship laced throughout this session, allowing me to lick and suck her feet in between being trampled. After this, i would like to have the mistress urinate on me, getting some in my mouth and body. Then I would like to be placed in the perspex toilet for the usage of the other mistresses, whereby they also urinate on me at thier leasure. All told, i would like to be used as a toilet for around four to five hours.
