A Champagne Toast

I have a fetish for filling my subs vagina with different kinds of fluids and objects. My favorite of course is a bottle of champagne :D (yes..ever since I saw the Rocco Sifredi film clip) because it gushes back out so wildly and drives my sub crazy. She says it burns and tickles at the same time. It started with a beer bottle once when we were both drunk. I have also used seltzer and water. Of course its more of a "party" when the fluid is carbonated. I have used ice dildos but she gets too numb for any further play. Has anyone else done this or used other fluids or unique objects. Also, the goal is stimulation or discomfort, not pain, so leave out the baseball bats. Is it possible to train her to hold these fluids for a period of time?

this girl love being told to use frozen grapes. She has used them to give her Master B.J's and he has filled her cunt with them and ate them out of her as well as fucked her with a couple of them in her. The heat of hei cock and ant coldness of the grapes is intense and so enjoyable for both of us. And when this gilr uses them while taking his cock in her mouth she doesn't have to sorry about sharp edges from ice cause she doesn't have to break them to use them. As for liquids this girl'[s Master hasn't done that to her yet but she thinks it is on his list of to do's .
