I've been waiting months for this moment. It's time to tell you how I feel.

I slink up next to you, lean down to your ear, "Hey there big brother... I've been missing you..." Why am I so nervous?

"Oh, hey sis, are you here?" You jerk your controller around, playing the game. Let's get your attention.

"I'm not wearing any underwear." I whisper in your ear.

You pause the game, looking straight at me. Bent over beside you, your eyes land on my cleavage. I pull the neck of my shirt down, baring more skin than necessary. "Wanna see?"

"Hey, what gives?" Frank grunts.

"I'm talking to my sister. Shut the fuck up a minute, jack ass." You manage to pull your eyes up from my tits. "Yes?" You reply to me.

Here goes. "Tell Frank to leave and you can have me. I'm yours. I want your cock. I want it so bad. I want your cum in me. I want you in my mouth. I want you in my pussy. I'll do anything for you." Fuck, I think even my tits are blushing!

You just look blankly up at me, and squint for a moment. "Anything?" You say blandly. Not... exactly the enthusiasm I was expecting...

"Whatever you want." I smile sweetly over to Frank, looking annoyed at our private chat.

"Absolutely whatever I tell you to?" You raise an eyebrow.

I swallow, and nod. "Absolutely anything."

You pause. "Prove it. Distract Frank so I can win. We bet $50 on this." Not... exactly what I was thinking...

Anything.

"Okay." I cross over to Frank. "Um, hey." I smile.

"What's up?" He just looks confused.

"Ready, Frank?" You say.

"Yup." He looks at the screen, the game un-pauses.

"My sister isn't wearing any underwear." You say, my face turning bright red. Not what I meant!

"The fuck!?" Frank looks up at my chest, nipples suddenly poking themselves through the thin fabric. "No shit!"

"Get naked, sis." You say.

Anything.

"Um..." I pull my shirt up, Frank eyes going wide as my large nipples as they come into view.

"Naked, sis." You say.

I push my skirt down, baring my smooth little slit to Frank as it slips quickly to the floor, leaving me totally bare. "Holy fuck your sister is fucking smoking, dude!"

"And... I win that round!" You smirk.

I cross an arm in front of me, wanting desperately to cover up. I wanted to show you, not Frank...

"Fuck!" Frank says, looking away from me as the next round starts. I glance awkwardly back at you, standing there naked in the middle of the room.

"God damnit... suck his cock, sis." You look frustrated at the TV.

I lick my lips, glancing down at the obvious bulge in Frank's jeans. Anything.

I step away from my clothes, discarded on the floor, and knee in front of Frank's chair. "No fucking way!" He blurts as I skillfully open his fly and free his very stiff cock.

I must have given a hundred blow jobs before, and for every single one, I imagined it was your cock. Frank's was no different: it was your cock I imagined as his slid effortlessly past my tongue and into my throat.

"Holy... fuck..." Frank crumbles in his chair as I slide on and off of his cock, deftly shifting between stuffing his whole shaft inside me to dancing my tongue around his head.

"And that's fifty bucks!" You chime from across the room as my head bobs in Frank's lap. "Now for some fun with that promise of yours, sis!" I pull off to see you picking up my skirt. "Oh, don't stop just yet." I turn, dutifully pushing my mouth back around Frank's cock. "Hands please." You take my hands behind me, twisting my skirt up and wrapping it around my wrists until they're tight together behind my back, my head still bobbing on Frank's now-twitching cock.

"Pull of him, sis." You order, and I oblige.

"Oh, come on!" Frank whines.

"Do your arms hurt like this?" You ask, ignoring Frank.

"No..." That blowjob was wet... drool is running down my chin and I can't stop it...

You shove the twisted skirt up my forearms, pulling my shoulders back with it as I wince, thrusting my bare breasts forward until it's binding my elbows behind my back. "Now?"

"A little..." I swallow. Drool is still all over my chin. I can feel it. Fuck it's bugging me. "Can you wipe my face off? My drool is bugging me..." I ask Frank.

"Don't like stuff oozing down your face, sis?" I walked right into that one, didn't I? "Stand up, Frank." I wobble back on my knees as Frank pulls up in front of me. "Make him cum all over your face."

My arms bound behind me, all I have is my mouth, and Frank's cock is point up fairly sharply. "Um..." I try sucking his balls, but I'm not certain this is going to work.

"Help her out a little with that thing." You say, and Frank tilts his cock down with his hand. I slide it into my mouth, looking up gratefully at him. He was about to cum before you pulled me off him, and he bursts in my mouth seconds later. I pull off, pushing the cum out with my tongue to let it dribble down my chin. He starts stroking himself, pouring little spurts across my face, my cheeks, my nose, my forehead.

I can feel it oozing already... Grr...

"Now the fun can really begin!" You say as I look nervously up at you through cum-streaked eyes, kneeling there naked, arms bound.
