Incest Seduction/Get your brother's attention
You try not to look right at your brother but you do your best to signal him. You're not okay with just giving your money away and you really want him to help you. Winning your bet with Zack is at the forefront of your mind. Even though Zack would be hurting his chances of winning that bet by helping, he does step in with another idea. A wild unexpected idea.
"Don't take her tips dude. That's not fair to her. Besides, shot glasses are cheap. If you're just looking to punish her... then maybe..." Zack starts, stepping behind you. "If you don't think she's looking hot enough right now, we could try to fix that."
Zack unties the back of your short skirt causing it to split and reveal each of the tight globes of your ass. He pushes the flaps of the skirt all the way forward until it hangs in front of you as bunched up layers of lace, making the sides of your hips and thighs fully visible. You're still wearing your g-string (for what little that does) but your slutty pseudo-dress just became a proper apron. Save for a few paltry strings, there is now an uninterrupted trail of bare skin going from your feet, up your short legs, over your bum, up your back, running all the way up to your hairline. In some ways it's like you're wearing half a dress, but just the front half.
Cam fails to suppress a smile as Zack turns you around in place, showing you off like a piece of meat. He clearly likes this idea. Whistles, laughs, and whispers are heard from the crowd. It's flattering and humiliating all at once. You suddenly go from minor fright and trepidation to outright embarrassment, your already blushing cheeks reddening a little more.
"Yeah? I mean, hey! If she wants her tips that bad, then sure! Do you Kim?"
Cam waits patiently for your answer. You step to the side and pickup your tray from the floor. While bent over, not only do you find your well toned ass sticking out behind you, but the skirt of your apron swings away from your body. It's hanging from those two vertical strips of fabric that are covering your tits, the strips themselves held against your body only by the single string tied underneath your chest. Now that the skirt is untied it is free to sway and twist when those strips drift away from your stomach.
This is such a precarious state you're in now. Merely leaning forward flashes your barely covered crotch to anyone nearby. Suddenly you're very thankful for your skimpy g-string, or else you would be giving an ass and pussy show. But you force those thoughts to the back of your mind. You have a bet to win.
Standing, you compose yourself and let the more confident Kim take the wheel again, shrugging coyly before replying, "I'm only here to get paid."
The muffled hoots and laughs from the audience get rowdier. You feel weirdly empowered that you changed the whole energy of the room just by agreeing to show a little more skin. It's like your own weird, sexy, confidence boost cocktail. But the crowd's opinion of you isn't what matters most; it's your brother's. He just gave you his approval - if not an outright request - for you to look even skankier than you already had wearing this poor excuse for a dress. He must like you this way, showing you off to the room the way he did. The thought brings you to smirk.
"Nice. Respect. I take it all back Zack," starts Cam, putting his arm around your brother. "You found a great girl. Hey Kim! Go get Zack another one of... whatever he's drinking!"
"One whiskey sour coming up!" you say as professionally as you can.
"Dude, what high school did you pick up this chick from?"
"Jesus, I told you, she's not a high schooler."
"Yet," you add in your head, "but soon." Although after thinking about it Zack is probably trying to pass you off as a college student. That's certainly nice of him. You'd be more than happy passing as a high schooler. But despite being shorter than nearly everyone at this party that was the first such comment you've overheard about your age. You must be doing something right. Wearing this outfit is probably all you need honestly. Few girls would ever be brave enough to wear something so brazenly revealing to a party. Although you don't think you're brave so much as motivated. It's still nice to not be thought of like a kid. You'll just have to be an extra good waitress from here on to hide the thinly concealed fact that you're a nervous and clumsy teenager.
You return with Zack's drink then keep on working and hustling. Dave doesn't have much to say about your wardrobe alteration. He just encourages you to make your money your way. And you keep trying your hardest, but getting tipped seems to be getting harder and not easier. Maybe there aren't a lot of people here who like liquor. Maybe they're all broke. Maybe you're too slutty now and people are keeping their distance. You can't figure it out, but you know that you aren't making the same kind of tips as when you started.
One thing that is happening is guys are trying to get your attention more often. They're just not buying anything. They want to talk, tell you how hot your outfit is, ask whether you have a boyfriend. You've been told 3 times by different guys "I've seen you in class" which is obviously not true. You try to deflect and keep moving through the party but you're not getting tips that way because you can't talk to anyone long enough to find out if they want a drink.
Obviously you're never going to make any money running away from people. So you lean on Kim, toss your cute pigtails, and try to flirt a little more. That works a lot better, once you eventually get tipped. But you're often forced to talk for minutes at a time before the guys realize you're not just here to fuck them and they decide to order something. Girls are easier to talk to but they don't tip as much either. It's better than no tips at all, but you decide you'd rather sway your hips a little more to try to get a bigger payout. At least until one guy pushes his luck.
He's clearly way too drunk already. You try to flirt and be nice at first but that gives him all the wrong signals. When you try to walk by him he steps in front of you. You go to the left and he grabs your sides and starts rubbing his hands over your waist. You try to turn and pull away and he pulls the straps of your apron away from your chest, twisting the dress to the side. One strap slips past your shoulder turning your halter into more of an arm strap, like you're wearing a frilly purse. With your chest and g-string fully exposed he gets even closer and starts grabbing your body, squeezing your tiny tits and pulling roughly on your nipples.
You scream. It's all you can think of because no one is helping you. You're not really fighting him either, otherwise paralyzed by the whole experience. But once it's clear you don't want this attention people start asking questions. Shortly both Cam and Zack find their way to you.
It all happened pretty quickly but it was still scary. Zack and some others kick out the drunk guy. Cam, still chill as always, apologizes as you fix your outfit and asks if you're good.
"I'm fine," you reply. You don't exactly know about that, but you're not hurt or anything.
"Cool. I didn't really want that guy here anyway."
And that's that. Cam starts chatting to someone else and everyone goes back to their own thing. You wish more came of it. True, it was just a drunk jerk. There are probably lots of jerks like him at parties. It just feels a bit deflating. Waitressing is hard enough. At least you know that people here have your back.
"She IS a stupid little bitch isn't she?"
Okay, maybe not all of them.
"It's her own fault. Who dresses like that anyway?"
Really? Are you hearing this right? A girl right next to you is talking all sorts of shit about you to her stuck up group of friends. She has to know you can hear her. Maybe that's the point.
"Yeah! She's hitting on everyone at the party so of course they all want to fuck her! Is there anything trashier? I've waitressed lots. This girl is a fuckin floozy."
"Umm... Hi," you interrupt, tapping her shoulder. She turns with a sneer, looking down at you like you're a cockroach. "Y'know I can totally hear you, right?"
"Please. Just. Shutthefuckup. I'd rather shit myself in class than be caught talking to you."
Yep. She's made it very clear. This girl is a total cunt. You sure don't have to think twice. You grab her own drink right out of her hand and throw it in her face.
She freaks out, starts screaming, and tries to shove you, but her friends grab her right away. That's pretty lucky because you were just as ready to fight this girl as she was. Maybe you just wanted to get some control back after being mistreated by that guy but you regret everything you just did the moment some of her friends get in your face while the others drag queen cunt down a hallway. Based on how they avoided outright violence, her friends are probably not going to fight you, but you can't be sure.
Cam watches the whole thing go down and steps in between you and the other girls defending their friend. It all gets really heated but the girls back down after Cam eventually agrees to sort you out, at which point they go off to check on their friend.
"Christ Kim. I can't babysit you. Can you stop fucking shit up?"
"Okay, but..." You check yourself, swallow your pride, and nod. "Sorry."
"I'm gonna have to ask them to leave too. They're gonna start shit if I don't."
"I said I'm sorry."
Frustrated, Cam gestures at you randomly, wildly, as if cursing in ASL, then says, "So?"
You shrug. "So what?"
"So how are we doing this? Are you going to punish yourself for that bullshit or do I have to?"
