Welcome aboard

"I can't believe you talked me into this." Jennifer grumbles to Ada, her best friend, who is sitting across from her on the train carriage."

"Relax, it's just a bit of fun. And for young women like us, so much cheaper!" Ada giggles.

And then, as the doors shut, and the train begins to move, a man's voice can be heard loud and clear over the speakers.
"Welcome aboard the Kinky Express International. As we begin our 16 hour direct journey to Berlin, please let me remind you of the most important rules aboard this service.

1) Women in green tops are riding with 'free' tickets. This means that they have submitted themselves to be completely free use for the entire journey. Please use their bodies to your hearts' content. Women in other colored tops are on discounted 'spectator' tickers and are not free use. You must NOT touch these women, but you are allowed to masturbate in their direction and verbally **** them."

Jennifer cringes at this, but Ada just giggles again. "It's just words. Get over yourself."

Jennifer looks down at her reddish top to reassure herself that she hasn't somehow accidentally worn green and doomed herself to 16 hours of non-stop degrading sex with strangers.
"If someone gets their cum on me, I'm going to freak out." She says to Ada.

Ada just giggles again.

The man continues his explanation through the speakers.
"2) Some free use women may express ****, or even passionate refusal. This is allowed, but does not mean that you should stop. No matter what they say, you should treat it as some sort of elaborate roleplay. By accepting a free ticket, they have contractually accepted that you are allowed to use their holes, even if they fight back and make you work for it.
3) As the Free Use women are enjoyed by our male passengers, we can obviously expect their clothing to be removed, or torn to shreds! Therefore, any woman with no top should be treated as if they were wearing a green top. That is to say - they are Free Use. Spectator ticket holders, it almost goes without saying, but make sure not to remove your tops, or we cannot be held responsible for what happens to you next!"

As if I'd be stupid enough as to remove my top. Jennifer thinks to herself, as she glances out the window to see the station platform already disappearing into the distance behind them.

And then, it happens so quickly that she doesn't even properly see the guy that did it. One moment, she's wearing her reddish top that makes sure people know they're not allowed to touch her, and the next, some evil man has ripped the fragile thing off of her. A split second later, he is sprinting down the carriage, and Jennifer just sees the black hoodie of this cruel criminal disappearing into the next carriage.

She immediately knows that she has absolutely zero chance of catching him before he probably throws the top out of the window. That is, assuming she could even confidently identify him.

"Jen! No!" Ada squeaks in panic.

"Fuck! What the hell was that?!" Jennifer responds in an equally high pitched voice.

"Quickly, put another top on!" Ada hisses.

"...Our baggage is all the way down the other end of the train!" Jennifer realizes.

"Um... Jen... I think... I think you... I think there's nothing you can do... Oh god..." Ada mutters weakly as she sees two lustful men already advancing on the poor innocent topless woman.
