Ask what you'd be doing

"What would I have do do?" You asked hesitantly, looking over at the complicated looking coffee machine behind the counter. There are two clear tubes running into of it from out the back that tickle your curiosity.

The green haired barista turns and follows your gaze, making an 'O' with her mouth as she taps into the source of your apprehension.

"Oh, you don't have to make any of the coffees! I'll handle that. But, I will need a hand churning up some of Candice's 'special' ingredients out back. Some of our regulars like a bit of breast milk and cum in their coffees. You know, for extra protein and vitamins or whatever?" The barista shrugs, completely uninterested in speculating further on her customers motivations. "We keep a couple of red collars tied up out back who have been augmented by the local lab for our purposes."

"Augmented?" You ask in confusion.

"Yeah, like full year lactation, higher milk production, bigger tits, that kind of stuff. The doc at the lab's crazy good at crap like that." the barista informs. "So, how 'bout it?"
