With another contest of course!

"Here's what we're going to do." Fiona explains, scorn sneaking into her voice as she releases your penis, shaking her hand and grimacing as if she'd touched something dirty. "Elsie and I are gonna give you another chance after your pathetic showing yesterday, to prove that you're not the quick-squirt, premo loser I bet you are. We're gonna watch these teen sluts on TV get their pussies wrecked," Fiona nods towards the television, where - indeed - a squad of well hung football players has somehow materialized and begun to crowd around the porn starlets, "And you're gonna get those hands to work getting us off."

You blink, not sure if you processed correctly that Fiona wanted you to give her, and not to mention Elsie, a handjob, but you set that aside for the moment because Fiona's not done talking yet.

"At the same time, Elsie and I will take turns with that peashooter you call a penis. You cum first, you prove me right, and you finally make yourself useful giving us blowjobs while we enjoy our movie night." She finishes, staring at you expectantly, eyes daring you to refuse.

But wait, hasn't she forgotten something? "And if I don't?" You ask, trying, and failing, to match her 'million-times-better-than-you' tone.

"As if-" Fiona snorts, then shrugs. "Whatever. In the one in the million chance that you manage to get Elsie to shoot before you do," you note she doesn't bother to include herself in the statement, "then she'll give you one or whatever. Now, are you in? Or do you just want to give up and admit your a bitch from the get go?" Fiona rolls her eyes, silently conveying that you're wasting her time.

Pass up handjobs from both your sisters? Not a chance, that much is obvious from the start, but, abruptly you realize that Elsie's been weirdly quiet this whole time. Shouldn't she have something to say? Is she just going to go along with Fiona's scheme without complaint? Or was this something she'd been in on all along? Twisting around, you look over at Elsie and... wow. Just, wow.

Legs now pulled up atop the couch, you little sister is staring vacantly at the porno, breath ragged and face gone red with arousal. She's pulled her nightie up even further, biting down on the top and holding it in her mouth to expose the entirety of her lower half. In the dim light cast by the television, you can make out one hand wrapped around the top of her swollen cock, jerking rapidly across the purple tip and smearing a steady trickle of glistening precum along her shaft. Elsie's other hand is darting back and forth between her pert breasts and the wet slit between her legs, fingers tweaking nipples and darting into her innermost depths with feverish determination.

It's a sight that leaves you stammering, but Fiona isn't fazed. Leaning over you, and no doubt intentionally dragging the tip of her cock across your t-shirt, she reaches out and gives Elsie's nipple a vicious twist. You wince in sympathy as Elsie gasps, eyes tearing up as she whips her head towards the two of you, blinking dumbly once, twice, as her mind reconnects to the situation.

"Huh, ah, OH!" She chirps, "you gonna play the game big bro? Awesome, this is gonna be so freakin awesome!" Ellie is practically buzzing with excitement and her cock is jerking up and down between her legs like a perverted metronome. "Ah yea, I told you yesterday we were gonna have fun and we are. Alright, let's do this big bro. I'm so ready to shoot my load down your throat, it's gonna be so hot popping your mouth cherry." Elsie pauses then, before sheepishly continuing, "Um, I mean, if I beat you Jesse."

Not even Elsie has any confidence in me you think to yourself somewhat dejectedly, before shaking your head. Whatever, you'll just have to prove yourself to your family and this will be the first step.

"Let's do this," you say, pulling down your boxes to match your sisters and reaching out to wrap a hand around each of their dicks, though around might be stretching the term with Fiona's you can't but think.
