Fingers

A burning desire took over her like wildfire. It fired up her throat and trickled down her spine, spreading to all of her nerves until her entire body was ablaze. She excused herself to take a moment's calm inside the comfort room.

But the confined space that was the cubicle engulfed her in flames even further. Incapable of resisting it any longer, she allowed herself to succumb: first a finger, but it barely made impact. She then inserted two, wiggling her fingertips around the warm- and wetness inside, until she made it three to reach the stimulation she desired. She thrust them deeper, her chest heaving as she tried to catch more air---

And then she squirted. She gave out a stifled grunt as the pool of sick flooded the depths of the toilet bowl, leaning on the door behind her as the force of releasing half of her dinner drained much of her menial strength and self-control.

After a few more minutes she went back to her friends, chewing in the next course after expelling dinner's demons, worry eradicated from her face now that there's room for some more.
