Incest Seduction/Make some money giving blowjobs
Is he really asking you to... Wow! You could make way more money sucking dick than serving drinks! You only sucked Zack because... well, he's Zack. You'd never considered just sucking any old dick. But it's not like it's hard to suck a dick. In fact it's kinda fun, and real sexy, so you're not against the idea. You should probably just charge more than what you got for doing Zack. You don't want to seem too easy.
"Oh, umm... no, it's $200. And I really don't want to swallow anything." Well, you'd gargle Zack's spunk if he wanted you to, but that's different.
"The fuck? Hell no! I'm not gonna pay you $200 to just lick it! I'd hardly pay twenty! Jesus!"
The newcomer elbows his friend and shakes his head, insulted by your offer. You've gotten a $20 tip for getting someone a drink, so that doesn't seem to compare with sucking a dick. But maybe you did aim a little high. You really don't know what the going rate is for this kinda thing, but you're still okay with taking whatever money you can.
"Okay. $50 then. But I'm not swallowing."
The guy smiles at his buddy then turns back to you. "That's more like it! But c'mon, you gotta sweeten this deal a little... how's about I cum on your face instead of your mouth?"
"Uh, I guess? Sure." You shrug. He wants that? Guys are so weird.
With a price settled he practically throws his money at you before whipping his dick out. He's mostly hard already and nowhere near as big as your brother. He's probably average as he seems about as big as the guy who started all this craziness, but you still don't have a good frame of reference for dick, let alone things like growers vs showers, something you heard some guys at school arguing over.
The newcomer parks his dick in your face and you quickly get to sucking. You work his shaft with gusto, not the least bit shy. It is a blowjob after all. You'd like to think you have a good work ethic and frankly you're still trying to show off. It could also be good to get him off quickly so that you don't have to suck on a stranger's cock for too long. But as you suck you start thinking that the faster you make him pop the more money you can make. All it would take is half a dozen dicks to finish winning your bet with Zack. How long could that take? If they take as long as Zack, two hours tops?
Speaking of, your brother seems to have disappeared. You thought you heard someone say that they wanted to buy him a drink, so he was probably led away downstairs (since the waitress is busy). You already miss him, but you suddenly feel very vulnerable sitting half naked with a dick in your mouth, even though you've been like that for the past 20 minutes. Zack's presence helped make you feel safe and assured, but now you're missing that.
"Well shit! I'm next!"
The guy's buddy reaches past his friend to tuck a fifty into your armband. There was this one time at the fair you saw boys lining up quarters to reserve their spot for an old arcade machine. That's now you. You're the arcade machine.
"Fuck, this girl's tongue is crazy!"
You're not sure what you're doing with your tongue exactly, but you keep doing it. You pump and suck voraciously until you can feel a change in his shaft. You've felt your brother cum enough times now to know what that means. You pull him out of your mouth and keep pumping but he knocks your hands away and takes over. He jerks himself way faster than you were and a moment later sends semen flying into the air in front of you.
You're not sure what you were thinking with this agreement, but staring down the business end of a shooting cock is a little scary. When the first blast hits you on the bridge of your nose you reflexively turn away. The shooter quickly grabs a pigtail and straightens you out, plastering your cheeks and your lips with more of his cum. You can already feel it trickling slowly down your face and you end up leaning your head back thinking, for no particular reason, that it should stay in one spot and stop moving.
"Fuuuck!" he sighs. "That's a money shot right there! Fuckin money!"
Just as quick as he whipped it out, he shoves his dick back into his pants now that he's satisfied. The whole thing, start to finish, only took a few minutes. A fraction of the time Zack lasted. At that rate you could make a lot more money than you need to! Or be done an awful lot sooner.
You start glancing around for where you should go to wipe this off when the buddy steps in front of you. His cock is already out and he's jerking furiously. Was he beating off the whole time he was waiting?
He doesn't even say anything to you. He just grabs your head and shoves you onto his dick. He's about the same size as his friend, maybe a little thicker, and despite the surprise of a new cock so soon you do your best to get back to work. It's jarring to have someone shove themselves in your face but it's an easy bike to keep riding. It's not like you're going to fight him off. He's just eager for his turn at the arcade. And he did give you his quarter.
This guy isn't quite as respectful as his friend however. To start he didn't even let you clean up first. And now he's forcing more and more of his dick into your mouth. Zack was forceful too but he's your brother and you trust him. He wouldn't hurt you, not on purpose. But this new guy seems inconsiderate at best. After a minute of testing you, pushing you, seeing what you'll let him do, he really gets to work. He has you by both pigtails and starts going hard, using your head like a fucktoy. Zack did this too, so you go with it. You do your best to stay calm but when he bottoms out in your mouth, making you gag, holding your nose in his pubes, smearing his friend's cum over his own crotch, you start to worry that he might just disregard your only established rule and cum in your mouth anyway.
You fight against him and eventually pull off, coughing and desperate to catch your breath. You haven't even recovered when he grabs your chin and starts shooting long messy ropes of cum over your face. The first lands above your temple in your hair and stretches down across your eye. The next coats your forehead down the tip of your nose, and then your other eye gets blasted, and he's still not done.
Very suddenly you realize how bad of an idea this was. If you let this continue you might make a lot of money but you'll be covered head to toe in semen. You probably need to rethink this. Why did you insist on not swallowing?
Once the second guy is satisfied and walks away you start scraping across your eyes with your nails so you can see without staring through cum. Other interested guys step forward but you wave them all away. There are sounds of groans and disappointment and perhaps an expectation that you'll keep going if they give you a minute to sort yourself out, but you continue to insist, unsure of where you can wipe your fingers.
"Hey! I'll pay you $200 to not clean that!"
You blink and squint towards the spectator shouting at you. "Huh?"
"You wear all that cum for the rest of the party and I'll give you $200."
Someone punches his arm, sounding more excited than disgusted. "That's gross bro!"
"I knew you were a weird fucker."
"Why? It'd be funny! And kinda hot! Tell me you don't want to see that!"
You watch as a bunch of guys make fun of their friend for suggesting you wear semen like a face mask. But you've already proved to yourself that you can do that. You wore your brother's spunk on your face this morning for way longer than you needed to and you didn't even get paid for that. It wouldn't be hard at all. The worst part of it is already done and you'd much rather get back to waitressing than have to suck more cocks. But you should probably make it worth your while if you're going to go through with it.
