After finishing her paperwork Zoe is brought back to the operating room on her own leaving you alone with Liz at the front desk. Knowing that everything is waiting on you you begin looking through the long list of potential options. Three in particular stand out to you: anus, buttocks (full), and buttocks (cheek). "What's the difference here? you have three different options for ass."
Liz looked more than happy to illuminate the situation for you. "Well for one you would just be inhabiting the anus and immediate skin around it. Essentially you would be the confines of her ass crack. This of course would entail processing all of Miss Albright's waste." She gestured to a mannequin in which on the body were marked to designate transfer zones. "The cheek option is for those ass-lovers who aren't quite ready for the scatological experience. Your time would be mostly spent being sat on and stuffed in her jeans but I'm told it can be quite enjoyable." She goes on. "And finally there is the full package option in which you would inhabit both anus and both cheeks for the best of both worlds."
You hated to admit it but there was something actually kinda hot about being the hole a trucker shit out of. You had never had a scat fetish before but then again you had never known about any of this either. "Would I have any control over anything, like could I make her fart or shit herself if I wanted?" Liz looked amused for a second. "Well while yes we do normally offer that option we do not in Miss Albright's case. She opts to maintain control of the function of all of her body parts. You would be at her mercy in that regard."
There was still one thing on your mind however: the taste. If you're going to be her ass wouldn't that mean you'd have to taste her shit? "Would I still taste it? Like is there any way to modify it so I like the taste?" Liz grabbed a different pamphlet and flipped to a page. "Once again that is an option we offer although technically it's a different procedure entirely that we perform on top of the transfer." The page said that essentially it could trick your tongue into thinking it tasted like something else, the example given being chocolate but apparently there were quite a few more options. "I know Miss Albright would prefer your senses are maintained as normal but she wouldn't stop you should you choose to take it. It is an additional 400 dollar cost, however on top of the 600 for the transfer that Miss Albright has already so generously paid for."
"I should note that Miss Albright has been with us since we started our original pilot program over a year ago. Her breast was actually one of the junior researchers who helped establish the program." The thought that Zoe's tit was actually a successful Scientist once-upon-a-time amused you quite a bit. "She's had quite a few clients and all of which have given her glowing reviews so I'm sure she would do everything in her power to make your time with her enjoyable."
This puts you at ease a bit. Zoe was nice enough in person but hearing it from someone else was reassuring. That's it you've made up your mind this weekend you'd be spending your time in the back of a trans-trucker's panties. You took the pen to the form and signed off on…
