You call your little sister, Shannon.

You sit on the edge of your bed, flipping through your phone for a moment. Your finger pauses over the name of your little sister, Shannon. You bite your lip, the throbbing in your panties growing suspiciously strong.

"Holy shit." You think to yourself. "Am I really thinking about seducing my little sister?? She's only 18 for fuck's sake! She doesn't even graduate high school for another couple of months." Yeah, it was probably better if this one stayed a fantasy. FUCK was she ever sexy though. Damn that Sappho for stealing your favorite dvd, it was hard to admit even to yourself, but fucking your sister had been a big fantasy of yours. Lesbian Seductions 8: Sisterly Love always got you off in no time. And ever since sweet little Shannon had filled out, it had only gotten worse. Spending night after night knuckle deep in yourself watching that dvd, imagining it was Shannon's face buried between your legs, licking and sucking bringing you closer and closer to...

Suddenly your phone buzzes in your hand, and you almost drop it with a little yelp. A picture of Shannon at last month's cheer leading semifinal fills the screen. You punch accept.

"HAPPY SATURDAY KRISSY! Its your wake up call big sis!" Shannon's upbeat voice pounds through the speaker.

"O-oh hey Shan, what's up?" You reply meekly, the picture of your sister in her cheerleading outfit immediately springing to the front of your mind.

"Oh come on, you can do better than that! What about, 'oh hey Shannon sweet sister o mine, how was your week oh light of my life?" Shannon snorts with laughter at her own mocking tone.

You grin, Shannon had always been so good at making you feel comfortable, her personality was near the exact opposite of yours, outgoing, bubbly, warm. She radiated charisma and everyone loved her. She wasn't as tall as you, and her boobs weren't as big, but in every other category she was better. By a mile. She was the cheerleading captain, you were the drama nerd. She liked going out and hanging with friends, you preferred quiet evenings at home. The differences should have made her easier to hate, but instead you two had really bonded growing up, despite the near 5 year age gap. In fact there had been times when she had felt like your only friend in the world. You hadn't come out to her yet, but at this point, considering how close you two were, she no doubt had strong suspicions.

"Ok, ok!" You laugh, relaxing a little. "Sorry, I've just been up for a while now and..."

"Stop the presses!" She teased, giggling. "Our little Krissy, up and out of bed before noon on Saturday? Who are you and what have you done with my sister? Has being a corporate drone made you a sad conformist already? You've only been out of college for a year!"

"If I want to get up and get dressed earlier than normal, that's my business. Just why are you calling anyway?"

"Sorry I'm not built like a giraffe like SOME people. I called cuz..." She pauses, suddenly sounding unsure.

"What is it, Shan?" You ask gently, leaning back on your bed.

"Oh nothing!" She laughs and you get the feeling she was about to say something important. "I just was suddenly thinking about you and I had a weird feeling... so... I just NEEDED to know you were ok, ok?? Is that so bad??"

"No sweetie, not at all. I'm fine, but its super sweet of you to call and check up on me."

"So all dressed up already huh?" Shannon's tone turned thoughtful. "So I gotta ask... what are you wearing?" She said it in faux deep sexy voice, but you could tell there was something else there, something...deeper. Longing...? Desire...?

You catch yourself playing with the ring. Oh no. OH NO. Was this....really happening? Your mind spins, you immediately think of ending the call, maybe blaming bad reception or something, or maybe...
