Check if she's ok.

It takes a moment to recover, your body still shaking form the intensity of your orgasm, but eventually you're able to gather yourself. You have to clear your throat several times before you can speak.

"Holy shit, Shannon, are you ok??" You ask, thinking of the loud thump you heard just before your orgasm blanked out any conscious thought.

You are about to hang up and redial her when you hear what sounds like the phone being picked up again.

"Shan?" You call into the phone. "Still with me hun? I didn't give you a heart attack or anything did I?"

"You...almost...did...sis!" Shannon is panting heavily, so out of breath she sounds like she just ran a marathon. "Holy shit... that was awesome Krissy! I've never...cum so hard... in my life!! The things you said....holy shit were they hot! I've never had someone.... talk like that to me! Who knew phone sex could be that mind blowing!!"

You couldn't help but agree, hearing your sister scream and moan and beg for you had been the hottest experience of your life, and the two of you hadn't even been in the same room!

A few moments pass, and Shannon finally seems to get her wind back. "Oh fuck, you would not BELIEVE the mess I just made on my sheets K! What is mom going to think??"

"Well how do you think I feel Shan? I've got to do my OWN laundry!"

There's a slight pause, then you both erupt into giddy post orgasm giggles.

"So Shan..." You begin.

"Mmm...yeah Krissy?" The way she says your name now has an almost purr to it that's hot as hell.

"What are your plans for today?"

"Oh I don't know... did you have something in mind, Krissy?"

"I mean, I really wasn't going to be doing much today, so you could, you know, come over to my place..." You trail off. Even after this morning's interesting turn of events, bringing yourself to openly propose your sweet little 18 year old sister come over and fuck your brains out wasn't an easy thing to say openly.

There's a pause on the line during which you hold your breath. Would she say no? Was she finally waking up to how fucked up this all was? What had you been thinking?? She was your sister, and you had said all those filthy things to her over the phone! What if your folks found out? What if...

"I'll be there in twenty minutes." *CLICK*

Lust and panic rise in equal measure as you set the phone down shakily on your nightstand.

You change into a fresh set of black panties, and you peel off the white T, but otherwise you leave your outfit just as it was. Why mess with perfection after all? Afterwards you keep yourself busy by tidying up the place a bit for your sister, a part of you humorously observing that you had never cleaned up for any of her other visits.

As you finish you hear the buzzer sound from near your door.

"Shan?" You ask into the intercom, trying really hard not to sound nervous.

"You know it, hot stuff." Shannon is once again using the faux deep-and-sexy voice she was using earlier when she was asking what you were wearing. You laugh, no matter how nervous you get, Shannon knows exactly what to say to make you feel completely at ease.

"Would you just get up here" You respond, laughing. You unlock the front door and head back into the bathroom.

Making some last minute adjustments in the bathroom mirror, you make sure to slip your heels back on, after all your sister is apparently a big fan! Shannon will be at your door any minute. Maybe queuing up a movie would help set the mood?

You walk up to your treasured dvd stack, your heels click-clacking on the hardwood of your hallway. You nearly do a double take when you see whats sitting on top of your dvd player. Lesbian Seductions 8: Sisterly Love. A little sticky note is attached.

"Really liked what I saw, but I figured you'd be needing this back sooner rather than later. xxxooxxxoo"

Why that sly little minx! You grin as you slip the disc in and hit play. You sit on the couch across from your big screen, crossing one leg over the other, remote in hand. Without hesitation you skip to your favorite scene.

Older sister "Hayley" had just come home and caught younger sister "Emily" masturbating, and had offered to show her sweet, nubile young sibling a trick or two. Not exactly Shakespeare, but it was enough context to get you going.

Unable to help yourself, you watch for a moment, entranced by the two women on the screen. They looked alike enough you could believe they were really sisters, and as Hayley slid her hand into Emily's jeans, movement from the direction of the front door catches your eye.
