Some thoughts:
The small 18 years old guys will jerk it while she gives them a show.
The conclusion would be that they cum too fast and cum on her.
To avoid the mess she could let them cum in her hands ( as already seen) or let them cum in her mouth. The moouth would be for sure the better option in many ways.
On the way to the bathroom to clean up the mess or spit it out she meets the girl and is forced to swallow it
