By now, it was almost noon- just three hours since Kelly found me in the kitchen trying to search out something to eat for breakfast and gave me her Quid Pro Quo ultimatum. Now, as we lay together in her bed, recovering from our explosive dual orgasms, I thought back to the last three hours and the revelation that my little sister probably had the hots for me as long as I'd had the hots for her. All that time peeking at her and stealing her panties..... I could have had the real thing if I'd only paid attention to Kelly more than I did.
"I was just thinking," Kelly said as she rolled over toward me, "we should make a list of all the nasty things we'd like to do with each other. We can call it our nasty fantasy wish list. Who knows when we'll get a chance like this again soon, Big Brother. You know, we'll be home together for at least three more weeks."
"Kelly," I replied, sarcastically, as I grinned at her, "what you really need is some basic sex education first. Every girl your age should already know how to give a good hand job, how to suck a man correctly, swallow cum.... things like that. Then we can work up to the nasty stuff once you're proficient with those basic skills." I chuckled to myself at my wisdom.
Kelly elbowed me hard in the side of my chest. "You sound like one of my stuffy old professors at school, Kyle."
"Okay, okay!" I exclaimed as I rubbed my side and laughed. "How about if we make a list of the top five nasty things each of us would like to do and we'll spend the Christmas break working on them?"
"Oh, Yes!" Kelly giggled. "When can we start?"
"Well, if you're really serious about it, we might as well start now since Mom and Dad will be gone all day." I answered. "Get some paper and something to write with," I suggested, "we'll make our nasty wish list and see how many we can start on today."
Kelly looked at me in disbelief. "Really?" She asked. "You're not teasing me?"
"Sure!" I replied. "But, we need some rules, first."
"Rules?" Kelly inquired.
"Well," I thought, "like..... we both have to agree with what goes on the list. And, you can't make fun of what someone wants to do. Plus, there'll be no backing out, Kelly. Once it's on the list, we have to make an attempt to really do it. We'll take turns listing stuff – you can go first, then I'll go, and so on."
"Kyle," she said, as she looked at me with a scowl, "that all sounds so official."
"Maybe so," I replied, "but, the rules will keep you from chickening out!"
"Like hell!" Kelly exclaimed. "So you think I'm gonna to be the one chickening out? What makes you think that? You don't know what I'm going to put on the list, Big Brother. I bet you chicken out first."
"Yeah, we'll see, Kelly. Don't forget who the scared little virgin is." I said, laughing.
"Just because I'm a virgin doesn't mean I'm a chicken." Kelly said as she crinkled her nose at me. "Don't forget who's been waiting for whom all this time, Big Brother." Kelly smiled at me, knowing she'd gotten the upper hand.
"So," Kelly asked after a short pause, "can these wishes be fantasies, too? Something we'd like to do, or see or try, and the other one has to help make it happen?"
"I think that's fair." I agreed. "I can think of a few fantasies you might be able to help me with."
"Sounds good." Kelly said as she jumped off the bed, in her light blue panties. Very un-lady like, she bent over to look down into her book bag. I couldn't help but stare at her cute little ass, wrapped in her panties. It was such an amazing sight – her wet panties weren't doing much to cover her at all, and from the back, I could see the flesh color of her shaved pussy through the wet material and one edge of her panties was trying to creep up between her pussy lips. Kelly looked back over her shoulder and saw me staring at her ass. Then grinning and shuffling her feet apart, she stuck her butt out at me.
I could only stare at her. The view I had couldn't have been any better if I'd planned it and posed her myself. Kelly's panty covered pussy, clearly on display to me from behind, was framed perfectly between her legs. And, as she dug down into her book bag to get one of her class notebooks and a pencil, she wagged her ass at me seductively, trying to act as if she was doing it unintentionally.
Finally turning around, she walked up next to the bed and stood there. "You really get off on looking at me in my underwear, don't you?" Kelly asked, peering down at my cock, which was starting to get hard again.
"Panties." I corrected her. "I prefer to call them panties."
"Tell me," my sister inquired, as she watched my cock grow in length, "if you had a choice, would you rather see me in my panties or completely naked?"
"Hard to say." I answered. "Both, I guess. I do get really turned on when I see you in your panties or catch a glimpse of them when you're dressed. But, it's been a fantasy of mine for a long time to see you naked – I mean..... up close and naked."
"I've never minded you seeing me naked, Kyle." Kelly replied. "I used to pray you'd come in my room each night after Mom and Dad went to sleep.... I'd pretend to be asleep while you looked at my vagina."
"Kyle," she added, as she spread her legs a little and tugged the waistband of the light blue panties up so the crotch panel was pulled up tightly into her, "you don't mind talking about this kind of stuff, do you?"
"Talking about what?" I replied.
