Stay quiet and hope they forget you

Maybe, if you're unobtrusive, you'll be able to slip away.

Unfortunately, an opportunity never presents itself. Kistel fucks you several times, each time taking longer to cum; by lunchtime, they're just walking around with you impaled on their cock and holding on for dear life. Your cunt is so raw that the crew can only use your mouth at lunch.

After lunch, Kistel gives you an actual job; go through a crate full of coloured boxes of some kind of powder, sort the boxes by colour, and put the different colours in smaller crates. Hey, at least it's better than getting fucked.
