"T-this one, ahhhh... next...." you manage to moan out while the head worker relentlessly fondle your boobs. She even has been teasing your nipples as well, which are making it very hard to think about anything other than pleasure at the moment. But you manage to still answer her question somehow. The head worker lady stops her assault on your tits and relaxes her posture while you take this time to catch your breath.
She has different plans for you though and forces you to bend down, almost in half, at the waist. If not for your new feminine body, you are certain something would have been pulled or broken with how hard she pushed you down. However, apparently this new body of yours is so flexible that your legs can easily wrap fully around your back, painlessly.

You really want to sit back up, but the lady is firmly keeping you bent over. She watches how your spine begins poking at your skin, slowly pushing it out further and further. You can feel what you think is your ass stretching out longer and longer, as your new tail slowly begins taking shape. Your new apendage reaches about 4 feet in length. It is there that it finally stops growing longer, only to start widening out a small bit, as new muscles grow in. It finishes by becoming coated in a shiny black coat of fur, which matches with your new hair color perfectly.

The lady gets the idea and releases the pressure from your back which her hand was making. Finally you can sit back up and stretch back a bit. Your tail stops flicking side to side and switches over to standing straight upright, showing that you mood has improved.
"Well now, that's quite the beautiful tail you grew there" she says, as she begins stroking your lower back. The moment she touches your lower back, right above where your tail connects, you suddenly feel extremely good, and your hips automatically begin pushing your lower back into her hand. "Oh? You seem to enjoy having this spot rubbed quite a lot. I'll keep a note of that for your owner."
You just bite your lower lip and moan while nodding. You also reach out and point to the tray labeled...
