Porn... It was obviously going to be porn.

Exposed in high def behind your older sister, a school bus full of busty co-eds wearing wet dream renditions of cheer leader uniforms somehow fails to come as much of a surprise. Really you rationalize it should have been obvious. After all, its not like you'd been invited to a movie night before you knew the entire distaff branch of the family was packing more meat than the New England Patriots. And yet, you still sit there, awkwardly staring at the screen while you process the fact that the first time you were going to watch porno with a girl would be with your sisters - as opposed to, say, your girlfriend, Allison. And if it weren't for Fiona walking back towards you with her stiffening foot-and-change of pussy destroying girl-cock, you might have had a better handle on whether or not that was a good thing.

Staring down at you, Fiona smirks. Up close and personal, her now-rigid prick meets your gaze from only a few inches away, a gleaming trail of pre leaking from the tip as if to say hello. Fiona's dick has a musk all of its own, both feminine and not that rolls over you from this close, equal parts arousing and confusing, not that that hasn't been par for the course already. Sitting stock-still, your eyes dart back up to meet Fiona's as her smirk twists into something cruel and... aroused? But you don't have time to ponder on that because a moment later, Fiona jerks her hips in a precise motion that brings her cock directly into contact with your mouth. A split-second of pressure, a moment of surprise, and you're suddenly left reeling back, lips smeared with precum from Fiona's heavy sack, the potent cloying taste unexpectedly on your tongue.

You stare up at Fiona, deer-in-the-headlights as your brain skitters and skips like a bad record, trying to get back on track. From behind Fiona the sound of the porno filters in - the cheerleaders are daring each other to flash their tits against the window or kissing or whatever. What would have had you riveted a day ago holds nothing on the fact that your older sister just...

She just...

She...

Just grabbed her cock in one hand while you were sitting there like an idiot and casually brought it up to smack one cheek, then the other, leaving the lower half of your face smeared with her leakage.

"Intimidated Jesse? Cock got your tongue? Awww, you poor thing." She lets out a callous laugh. "I'd be too if I'd been born with a needle-dick like yours. Hell, I wouldn't want to show my face for the shame if I had your package. What a fucking disappointment."

You want to say something, anything really, but you're still to stunned to even start forming the words on your lips, and you just sit there blushing until Fiona lets out a derisive grunt and presses herself down on the couch beside you, arm and leg pressed against you, leaving no space for you whatsoever.

"But maybe I'm wrong, little brother. Maybe there's a man in you after all and not the little bitch I saw jerking off with my panties yesterday. Tell you what, " Fiona reaches between your legs to unceremoniously fish your erection out of your boxers and smirks again as her hand easily envelops it, "lets find out."
