Gain glory from the hole

As soon as she was inside, Lisa noticed a few holes around the cubicle, and when she turned toward the door it was closed. Due to the drunkenness she didn't panic, and instead asked “Why is it closed? What do I have to do?”
She heard Silas laugh from the side "Don't worry, i'm just making sure you won't run off before paying your dues. As for what you'll do... well, just as the name implies, you'll be an attendant serving any guest in need of a toilet"
Drunk Lisa still didn't understand, especially since she was currently locked in a toilet stall. Silas didn't care, and to stop her from asking any more he barked "Stop asking so much and just wait, you'll get a gist of the job soon enough. Do a good job and you'll be out of there soon enough... be warned though, if i hear even a single complain then you'll be no attendant no more, just a toilet to be used like one"

She still understood very little, but a demotion to toilet sounded bad even to a drunken Lisa and so the girl steeled her intoxicated resolution, determined to be good at whatever will be thrown at her.

Determination she'd need very soon, and a ton of it as well as her eyes watched in confusion as an enormous log of black erect meat got pushed through the hole to her left.
It took the girl a few seconds to realize it was an enormous cock that she had to deal with, and yet the understanding only made things worse as the drunk girl froze in embarrassment, shock and a tiny bit of drunken arousal.
However the man on the other side would have none of it, grumbling "Hey girlie, my john ain't gonna suck himself and i ain't paid to hump the air so get to work, will ya?!" the voice sounded older than she'd like and definitively drunk, yet it definitively did the trick and snapped her out her trance as the man humped the hole, making his dick bobble up and down in front of her eyes.

In a different situation that sort of thing may have gotten an entirely different reaction out of her, but as drunk as she was and knowing she was here to work, knowing he paid for her to suck made it pretty clear how she'd have to earn her way out this shithole.
