You use some mental gymnastics to justify your actions

As soon as you see the butts, you already deep down know that you're going to cave.

These three fine fat-assed women are suspended in the wall by tight, rigid, padded holes. One each of them, all you can see are their hands, feet, and thongkini-clad buttocks. And the swimwear that has been chosen to clothe these convicts leaves little to the imagination. Indeed, that brown chick on the right's blue bikini bottoms are so tiny and tight that they are harshly digging into her pussy and ass crack. You can actually see her labia, and you can tell by the way her fingers and toes can't stay still, that she's desperately uncomfortable.

There's no way you can hold back and leave here without getting your dick wet in one of these fine holes, and you can sense that the other eleven men to your sides feel the same. But still, you go through the motions, coming up with logical justifications for why it'll be okay for you to fuck a butt tonight.

It's just a butt in a wall. Sure, it's a real person, but it might as well just be a sex doll.

There's no intimacy. You don't even know their names. You've never even seen their face, or heard their voice. How can you call that cheating? Watching porn is more intimate than this.

It's important for the case. The defence lawyer said so. This is about justice.

These women are here to pay their debt to society. It's your role now to help them achieve that goal.

Your relationship with Julia is on the rocks anyway. You'd regret it for the rest of your life if you were to miss out on this opportunity and then end up breaking up with her in a few day's time.

And finally... She accused you of cheating. This feels like a poetic way to (privately and secretly) punish her for that injustice.

"The woman on the left has almost paid her 'fine', so she'll be released after one more person uses her."

The uniformed prison officer turns to look at the woman with the orange thongkini. She seems really jaded already, speaking so casually, as if she wasn't talking about what is essentially this woman being used against her will in front of her very eyes.

"Does none of this bother you?" You ask, a little unsettled.

"Why the hell would I be here if it did?" She shoots back.

Good point, you think.

"So, who's going to go first?" She asks, before turning around and looking directly at you. "Well volunteered."

You look around you in confusion, and see that everyone else has stepped back a step or two, leaving you clearly out in front. This, combined with the fact that you're the only one who's said anything, makes it seem like you're by far the most eager.

"Well, which one are you going to fuck?" The prison officer answers impatiently.

Well, if this is really happening, who cares if I'm first or last or whatever.
