You already saw me in your mirror when I first showed up. You’re just seeing how far I’ll take it now.

I am seriously going at it back there! Fuck, you didn’t expect your little sister to be hotter than freakin’ porn, but you’re not even watching the laptop at this point.

“That’s not fair! I could do that!” The red head is apparently ready to take her turn on this guy’s cock, but your eyes are glued on me. This little rearview mirror on your laptop is awesome, if small: no one ever notices it. It’s saved you a few times now. You wonder just how far I’ll go.

You turn your chair, just the chair, and your legs, and your cock, to the left. But keep facing the screen. You brace the floor like it’s just a normal way to jerk off, all twisted and sideways. My eyes go very wide as your cock comes into view.

“Double or nothing?” The blonde giggles.

The only problem with this little mirror is that it’s, well… little. You can see my face, but little else. There’s plainly more worth seeing there…

Fuck it.

You pause the video and turn, spinning your chair to face me as you smile. I’m standing there in my cute little jammy shirt, the one my panties always peek out of, only this time, there’s no panties. My fingers are frozen, buried inside my smooth little pussy lips, my other hand playing with my braless breasts. That look of panic clearly means I thought you’d never notice me.

You try to think of something to say. Something to convince me to suck your cock, maybe? You're about to make a mess? That’s fucking stupid. You could use a hand? No, no hands! Am I hungry? What the fuck does that even mean? Always good to start the day with a protein shot? Uh...

Fuck it.

You stand, stepping toward me, your hard cock the first thing to press into me before your arms wrap around me. Your lips meet mine and I melt in your arms, my entire body melting around you. You never realized your sister was so fucking horny! I start kissing down your neck, your bare chest, you pull off my shirt and as soon as my hands are free I roughly yank down your boxers. You kick them off and I drop smartly to my knees, as if I could read your mind. My kisses work their way down your taut stomach, through the neat little bush of hairs, teasing at your balls before working my way along and up to the tip of your cock.

You quickly realized I'm a fucking pro at blow jobs, and wonder just how horny I've been while you were away. I take your whole length in on the first press, straight down my throat, and it feels… incredible.

You don’t want to wait for the slow roll, and grab my head, fingers tangling into my hair, guiding me back and forth on your cock. You’re so deep in my throat, and it feels so good. You only pulling your head out into my actual mouth once or twice, and I expertly tease you with my tongue when you do. You’re nearly there. It occurs to you briefly that maybe you should stop and, like, reciprocate before you cum.

Fuck it.

You pull my head hard against you, your cock pressing deep into my throat. I don’t gag in the slightest, even as you start pumping cum into me. Fuck, you’re cumming down your little sister’s throat and it feels so fucking good…

You let go and I slide back, a last dribble of cum dangling between us as I pull up, wiping it off my chin with a smile.

“Welcome home, big brother!” I grin, turning, heart racing, bouncing off naked toward my room.
