She's fucked pretty much every guy in the bar

You and Mia return to the bar to find things have quietened down, it's getting pretty late and you suspect a lot of people have gone home for the night. You start making your way towards the bathroom when you're interrupted by the guy you were playing pool with earlier.

"Hey man, you didn't give me your number earlier so I can collect on your debt." He turns to Mia and says "Damn hoe, you've cleaned up quickly. I can't wait to have you all to myself. Although I might've mentioned you to a few other guys who might wanna have a turn with you too. I hope that's alright."

He's clearly gotten Mia confused with her twin sister, but she doesn't say anything in response as she's quite confused by this exchange herself. You gesture for the college kid to give you his phone and put your number in so the two of you can organise for him to take Tracy for the 20 hours he had 'won' playing pool. He leaves with a satisfied smile to return to a couple of his friends who are still playing pool and the group starts to pack up to leave, clearly he was just waiting at the bar for you specifically.

Whilst you and Mia continue on to the bathroom you know you'll find Tracy in (since she's handcuffed and couldn't have really gone anywhere) Mia starts to question you.

"So what was that all about?"

"I made a deal with that guy that he could have Tracy for 20 hours to use however he pleases."

"So is that how the two of you work now, you're like her pimp, whoring her out to other men?"

"I guess it's sort of like that, although I'm not exactly whoring her out since the men never have to pay. Basically, your sister is a nymphomaniac slut, and in order to keep her satisfied I've taken over her sex life and put her in various situations where she'll be taking a whole lot of dick. From what you were saying earlier about hooking up with lots of guys in bars it sounds like the two of you have a lot more in common than just your looks."

Mia lets out a soft *hmphh* and stares at the ground in shame. Even if she did enjoy hooking up with a number of strangers from a bar, she obviously wasn't on the same level as her sister. Speaking of Tracy, the two of you had now reached the bathroom she was located in. It's a lot more empty than the last time you two were there, in fact there's no one in sight anymore. The two of you walk down to the end of the row of bathroom stalls to find Tracy on her own, still locked in her precarious position.

Tracy looks like a mess. She's down on her knees bent over the toilet with her face turned to the side, down on the lid. Her bare ass is pointed out towards the two of you and you can tell that both her pussy and her asshole have been used thoroughly over the past few hours. At some point her top has been removed so her perky tits are being squashed down into the toilet lid as she lies there. Her skirt has also been completely removed now and tossed onto the floor alongside her top. The one piece of clothing she is still wearing are her thigh-high boots, which have a number of used condoms tucked in around the top and dangling down. There are a number more scattered around the bathroom stall on the floor, with some more on her back and a couple in her hair too, which you notice is also a mess. Looking into her purse which is still dangling from the door, you notice that the condoms ran out at some point, which explains the cum running out of her holes. Her body is also covered in some sort of liquid which you'd need to inspect closer to identify.

"Oh my god!"

Mia is clearly shocked by the trashy appearance of her sister, not having noticed the finer details through the crowd earlier, such as the handcuffs still attaching her to the metal bar on the wall. Tracy recognises her sister's voice immediately and turns towards the two of you with a shocked expression on her face.
