Kelly smiled as she leaned back on her bed and threw her legs up over her head and spread them wide. It was an incredible sight to behold; my cute little sister, naked, except for her light blue panties stretched tightly across her pussy, so lewdly displayed in front of me. Her panties were so wet, they did very little to hide her mound, and they clung to her labia in such a manner that I could completely make out the shape of her lips as they pushed against the material. It was, without a doubt, the hottest and most vivid view of a girl in her panties I'd ever seen. My cock throbbed as I looked down at the juncture of her thighs, and all I wanted was to stop time so I could look at her like that.
Her breasts, although not huge, weren't small either and they juggled on her chest while her nipples stood at attention. I've never been a 'Breast Man' so to speak, but, I do appreciate a nicely formed set of tits. Kelly's were almost perfect, though. I don't know if it was just the fact that my own sister was voluntarily baring her breasts to me, or that I suddenly became a 'Breast Man', but, whatever it was, they looked good enough to eat, and for a few seconds, I thought seriously about sucking one of her elongated nipples into my mouth and tonguing it until she screamed and begged me for mercy.
She stayed in that position, letting me look at her near naked body for several minutes. It was almost as if I was having my own slow motion fantasy with her posed there as she was -- legs wide open and intentionally displaying herself to me. I'd always dreamed of having her like this and now, my dream was being fulfilled.
I looked up at her face and she was grinning at me. Then, as if she'd just had a brainstorm, her eyebrows peaked up three or four times. "Kyle," she said seductively, "I wasn't kidding when I told you I wanted to see you stroke that thing in your hand, but, I was just wondering if you'd rather I took my panties off so you can look at me completely naked while you make yourself cum, or, if you'd like me to leave my panties on so you can sniff them while I'm wearing them?"
Shit, Kelly wasn't kidding about wanting to be a nasty little sister, was she! Believe me, I wasn't the least bit squeamish about beating my meat in front of her, and here she was asking me if I wanted to masturbate with her baring all her feminine charms to me naked, or if I wanted her to keep her panties on while I did it.
"If you leave your panties on, can I touch you?" I asked.
"Well, duh!" Kelly replied. "If you're eventually going to make love to me, you might as well go ahead and touch me as much as you want." She said smiling.
"And," I continued, "would you be okay with it if I.... you know..... rubbed my nose down there and sniffed and licked you a little, too?"
"Oh, I'd definitely be okay with that, big brother." Kelly answered, giggling. "But, what ever you do," Kelly continued, "you're still going to play with your self while you do it - and I mean all the way, Kyle. I want to see your sperm shoot out. You have to face me so I can see you clearly when you're ready to cum. Got it?"
"Fuck!" My mind cried. It's like she pulled this from one of my own sacred fantasies. She was going to let me touch her -- I mean actually touch her pussy and her panties, sniff and lick her, and all I had to do is let her watch me jerk myself off? Not only yes, but hell yes!
"Fine with me, little sister!" I exclaimed. "Leave your panties on, then."
"Okay," Kelly replied, "you tell me how you want me and you're free to touch, lick, suck, rub..... whatever your little heart desires. But," she added, "I don't forget I get to watch you, too. This is Quid Pro Quo, remember? It can't be all about you. I want a good view of what you're doing to yourself."
"I know, I know." I said. I asked Kelly to move to the center of her bed and then pull her legs back up -- way up, so her panty covered pussy was pointing straight up at the ceiling. I stripped my jockeys all the way off and climbed up on the bed on my knees right next to her. In that position, my cock hung over her belly button and my left hand could easily reach down to her panties while my right hand stroked my pole. God, this was going to be unreal. I was going to be able to feel between her legs while jacking myself off.
Kelly's eyes were locked on my cock as I started to stroke it again. Wanting to give her a good show, I twisted my midsection toward her head and leaned across her body. In that position, my cock was right above her face, only inches from her mouth -- and I smiled down at her as I continued to stroke it. Kelly's eyes got wide when she saw how close she was to my cock, but you should have seen the look on her face when I stopped stroking for a minute and bent my hardened member down so it was pointing right at her mouth. My cock head was so close to her, if she'd have stuck her tongue out, I could have wiped my cock it.
I couldn't have planned what happened next any better if I'd done it intentionally. And, I was just as surprised as she was when a drop of precum fell from my cock head and hit her on the side of her cheek! Her head jerked to the side when she felt it, causing the shiny fluid to run down her cheek, leaving a clear and slimy trail on the soft skin of her face. I laughed when she flinched, then I got a truly dubious idea.
Grasping my cock closer to the base, I waited until she moved her head back to where it was and I looked down at her. "It's just precum." I said. "It won't hurt you."
"I know." She said, sarcastically. "I just wasn't expecting my big brother's penis to drool all over me."
Thinking quickly, I replied, "Juice for juice, Kelly. Quid Pro Quo, remember?"
I don't know what made me do it, but I lowered myself and guided my cock toward her lips. The look on her face as my cock traveled the few inches toward her mouth was priceless -- it was a mixture of fright, surprise and longing. As I inched my pole closer and closer to her lips, my sister opened her mouth -- just like a baby bird waiting to be fed, and I knew she was prepared to take the head of my cock into her mouth when I got close enough.
Instead, though, I stopped about an inch from her and started squeezing my cock, milking several drops of my precum out of the end of my cock. Each drop fell squarely into her waiting mouth as she held it open. Then to finish off my nasty display, I wiped my dribbling cock across her lips and raised myself back up and smiled down at her.
Kelly was completely blown away, laying there with her mouth still open and her eyes staring at my throbbing and pulsing cock. "Go ahead," I urged her, "taste it."
As if she was in some kind of trance, my sister closed her mouth and swirled her tongue around in her mouth as she tasted my precum. She never took her eyes off my cock, though, and as I settled back on my haunches to resume jacking myself, I casually asked, "When I'm ready to cum, where do you want me to shoot it? On the floor?" I asked.
It took Kelly a few seconds to snap herself out of her precum eating trance, and when she did, she asked, "Is it gonna be a lot, or a little?"
"I can almost guarantee it going to be a pretty healthy stream." I answered. "Considering how worked up I am and the fact that I'm going to bury my nose in your panties and suck as much of your pussy juice through those panties as I can, you better be ready for a flood of cum."
