Return to the help desk.

You return to the help desk to find the librarian spread out, her green sweater popped open at the buttons, and her two ample, fully exposed breasts swaying up and down as she moans rhythmically from pleasure. The guy who had been in front of you in line was mounting her, fully clothed except that his pants were pulled down to his knees with the side of his ass protruding beyond his untucked shirt.

They don’t seem to care about the noise they are making — a loud rumpus reverberating throughout the entire building — or the fact that with every thrust, they knock papers, books, and pencils about and onto the floor. They’re definitely enjoying themselves, though.

As startling as stumbling upon two people having loud sex in public can be, what is perhaps more starting is the lack of reaction you notice from anyone in the vicinity. Not a single person — student, faculty, or otherwise — reacts to the brazen sexual display. They respond to the sounds as they would music playing in the elevator, giving as much (or little) attention to the scene as they would a fish aquarium or an ornamental plant. That is to say, no one seems to give a fuck.

You look back at the librarian’s voluptuous breasts. They seem perfect. You’d like to get a closer look (hell, you’d love to touch them!), but as of now, the two haven’t noticed you. Moving closer might change that. On the other hand, you got this strange book in your hand - and while it’s not the book you were looking for, you can’t help but think it’s related to this weird sexual encounter. It might even make sense to take the book back to your dorm room for further study.
