Jackin' Jacks

After a long while, Kelly rolled onto her back beside me and stretched lazily. As she yawned, her movements pulled the sheet sideways off of me and briefly exposed my hard cock. I scrambled and grabbed the sheet immediately, pulling it up all the way up to my chest as Kelly lazily turned her head towards me.

"Morning Jacks" She said in a half whisper, still rubbing her eyes.

"Hey you. I guess you got cold or something last night?" I asked, sitting up against the headboard.

"Kind of." She said, laying her head on my leg. That certainly didn't help matters. "I got up to pee about 2 o'clock, When I got done and came out of the bathroom, I saw you laying there. You looked so warm and cozy, I decided to cuddle up next to you."

"Well, it is good to know that I'm cozy at least." I said with a smile.

"You are. I feel a lot better this morning. Thank you, big brother." She sat up and kissed me on the cheek, so sweet and innocent. Then she slid out of bed and into the bathroom.

I took the opportunity to scrounge up a pair of boxers and my running shorts to put on. My erection had subsided somewhat, but I felt uncomfortable sitting there in bed talking to my sister while I was naked. I was pulling a t-shirt on when she emerged from the bathroom. She smiled at me and headed out to the living room. I went into the bathroom and cleaned myself up a little, brushed my teeth and washed my face. I put on my knee brace, grabbed my running shoes and prepared to head out for a morning run.

I went out to tell Kelly where I was going but was distracted by sounds coming from the kitchen. I saw her on her tiptoes, trying to reach the upper cabinets to open them. Her body stretched to its limit, her top strained against her small breasts and her shorts riding up higher into the cleft of her perfect little ass. I had to shake the image from my head as I reached above her and pulled the cabinet open. It was empty. She turned to frown at me.

"So, I thought I'd make you some breakfast," her voice rang out, "but there isn't much here to work with. No eggs or bacon. Not even bread to make toast with. Or milk. Or cereal."

"Yeah, breakfast isn't my thing. Usually, on most days, I eat an early lunch and then just a small dinner after I work out."

"Well then." She sighed, then noticed my shoes. "Are you going somewhere, Robo-knees?"

"Funny. And it's Robo-knee. Just the one leg, remember?" I joked, slapping the metal brace on my right leg. She had decided when she was 11years old that my knee brace made me a robot.

"I'm going for a run. I'd rather run before the heat of the day sets in. I can take you back to the dorms when I get back."

"Oh, sure," she sighed. "I guess I'll be ready."

I took off on my run. Even though I wasn't the superstar athlete anymore, I did my best to stay in decent shape. I tried to run in the morning every other day or so, and usually did some sort of work out most evenings. The runs helped me clear my head and get ready for the day.

Today, I thought about my date that evening. Pamela was another grad student who had only been on campus for a semester now. She was a former volleyball player, and her smoking hot body reflected that. Her scrumptious thick thighs and round bubble butt made me salivate. She was a chemistry student, working on her masters, and her lab was clear across town in the new extension campus. It was only by chance that our paths had crossed in the business office. I was determined not to let that chance be wasted.

She was smart, funny, and had one of those smiles that you couldn't look away from. I'd been texting and talking to her for weeks now, trying to convince her to go out with me. She finally accepted, and I was very much looking forward to turning on the charm with her.

I walked back into my apartment to find Kelly was sitting on the couch, still in the old t-shirt of mine. I told her I was going to take a shower and get dressed. She smiled half-heartedly and nodded. "You alright sis?" I said, stopping in my tracks. Her face was red.

"No." She burst out bawling out of nowhere. I went back over to where she was, pulled her to her feet and hugged her close to me. She cried hard for a few minutes. I had no idea what to do or say. I felt foolish just standing there holding her, but what else could I do?

Her sobs turned into silent shivers, her shoulders vibrating with every shudder. I eased us to the couch and back into it, making sure Kelly landed softly against my chest. She calmed down shortly thereafter and we sat there silent for an agonizingly long time. I had no idea what to say, or what to do. Do I ask? Do I wait for her to tell me? I just held her head to my chest, waiting out the tears.

"Jackson?" She finally piped up.

"Yes?"

"You stink." She giggled softly and rolled off me and onto the floor. I sat up and stretched my arms up.

"Well, I was heading for the shower."

"You need one. Go." She shooed me away with her hands comically.

"As you wish." I replied with a bow, drawing another small laugh from her. She loves The Princess Bride almost as much as I do. That was one of the few intentional influences on her I had while she was growing up.

I turned on the shower and cleaned the eight or so miles of sweat off of me. Kelly still seemed pretty down. I wondered if she'd be ok on her own tonight. I had put in so much time and effort into even getting this date with Pamela, I cringed at the thought of having to cancel. But I would feel really bad leaving my sister alone if she wasn't up to it.

I stepped out of the bathroom and dried off. I tossed the towel aside and opened the door into the bedroom. I froze immediately. I expected to see an empty bedroom, just as it was when I had gotten in the shower. Instead, I see Kelly in my bed, blanket pulled up to her neck, eyes glued to her phone. I backed up and slammed the door shut right as she looked up. Had she seen me? Dammit why was she in there in the first place?

I wrapped the towel around my waist and opened the door again, slower this time. Kelly was still there in the same spot, eyes still rooted to her phone. She looked up momentarily, then back to her device.

"I'm sorry about that. I didn't know you'd be in here" I apologized.

"It was my fault." She responded, never looking up. "I needed to charge my phone. I forgot to bring my charger, and you don't have one out there. This one is plugged in behind the bed and I couldn't reach it, so I just got comfy instead." She said, her sparking green eyes flicking up to meet mine for a moment before returning to her screen.

I rummaged around in my dresser, taking some boxers and walking shorts with me to the bathroom. As I dropped the towel and pulled them on, I realized my cock was getting hard. Not ready-to-fuck hard, but enough that it was going to be visible under my shorts. I guess the shock got the adrenaline running through my veins and pumped me up somewhat.

I emerged running a comb through my hair. Kelly noticed what I was doing. "Are you going somewhere else?" She asked in a quiet voice.

"Well, I figured you'd need to go back to your place, and plus..." I caught her puppy dog eyes looking up at me, "I have a date tonight."

"And you don't want your little sister around while you get some pussy. Got it."

Her sudden vulgar language shocked me. I had never heard her speak like that. "It isn't that I don't want you around..." I said as I pulled a shirt over my head, "it's just that ..."

"I get it." She said with a huff, cutting me off, "You're kicking me out."

I sat on the bed beside her and put my arm around her shoulders. "I'm sorry Kel. I didn't mean to make it sound like I was kicking you out. I've had this date planned all week."

"So, it's a first date?" She piqued.

"Yes, it is. I had to work really hard to get it too. It took weeks and weeks of wooing her to get her to say yes," I replied.

"Wow. She must be hot to go through all that effort wooing." She smiled. I was glad to see her smiling again.

"She is. She used to be a volleyball player."

"That means she has a nice ass," she said, smiling.

I laughed. "Very much so. And thighs that could probably crack my skull like an acorn."

"And you'd like that I bet. Does she have big tits too?" She grinned.

"I wouldn't say big. They're nice. Probably B cups if I had to guess."

"A lot bigger than mine anyway." Kelly looked down her shirt and crossed her arms in shame.

"Size isn't important." I tried to sound reassuring, although it was a bit awkward. "They fit her frame well, that's what makes them sexy."

"It's kind of funny hearing someone say, 'size doesn't matter' when they're not talking about a guy's cock." She giggled.

Again, her language caught me off guard. Pussy, cock. Since when does she say things like that? "Yeah, well, that's a thing people say." I shrugged.

She sat quiet for a moment. I stood up and stretched. I was about to go to the kitchen for some water, when suddenly, out of the blue, she blurts out "I wish mine were bigger," and covers them with her hands.

I sighed, sitting back down beside her. "Kelly, yours fit your body. You're small, thin and petite. If you had some big 'ol double D's, you'd look like you were about to fall over when you walked."

She laughed softly, then stood and looked at me questioningly, eye to eye. "So, you're saying you've looked at my boobs before?"

"No, that's not what I meant... I... Umm, you see... What I meant was... I haven't tried to look, but..." I stammered, caught totally off guard. Kelly erupted into laughter.

"You should have seen your face! Priceless!" she shrieked, falling back onto the bed laughing at me.

I sighed and gave her a congratulatory slow golf clap. She got me good there. She sat up and leaned her head against me.

"Jacks, I really don't want to be alone in that dorm room tonight." She whispered.

"You can stay here." I gave in. Of course, I did. I was always going to give in.

"Even if it means you won't get laid?"

"Even if I don't get laid. Who knows, maybe we can go to her place instead." I said as I kissed the top of her head.

"You're assuming she would want to have sexy times with you in the first place," she said, smacking me in the gut. "Typical man, thinking with his dick."

"Yeah, well he's been right more often than he's been wrong. I let him think all he wants," I said, drawing a smirk from Kelly.

"So, my brother is a player. You're a bad boy, Jacks," she said, still smiling.

"That's not what they tell me."

Kelly smacks me on the arm as she stands up, as she seems to be blushing somewhat. "How about you take me to lunch first? I'm starving, and there is almost no food in this place," she half asks, half orders.

"Sure. Let me grab some clothes and you can get ready in here."

She went into the bathroom as I grabbed a nicer set of shorts and a polo shirt. I got to the door and started to double back to the dresser for some socks. As I turned around, Kelly poked her head out of the bathroom door. I could hear the water running behind her. Even though she had cracked the door open just enough to put her head out, I was standing at just the right angle to see the mirror behind her. I had a pretty clear view of the reflection of her cute little naked butt. I couldn't help but stare. I knew my sister was attractive, but seeing her naked, even if it was just her back and ass, was a bit of a shock.

"Hey. I decided I want Indian food."

"Uhh... Sure." I replied, trying not to be obvious that I was staring. Dammit. And then she didn't close the door all the way behind her. The steam was starting to billow, but I got a fleeting glimpse of her perky tit, with its hard, pink nipple, as she stepped away from the door. And there was her cute little ass again as she pulled the shower curtain back to step in.

I stumbled to the living room and finished getting dressed. I grabbed my phone and messaged Pamela and told her I was looking forward to seeing her tonight. To my chagrin, she was now backing out on me. She said she had a family situation to deal with this weekend and wasn't going to be home. This sucked.

I guess my face showed my disappointment as Kelly emerged from the bedroom. She was dressed in another pair of very short shorts and a tight little sea green top with no sleeves. "What's wrong?" She asked immediately. I just grumbled and shook my head.

"She cancelled on you, didn't she?" She asked, running a brush through her flowing blonde hair.

"Yeah, she said a family thing came up and she had to be out of town." I said, tossing myself into the couch.

"I'm sorry Jacks. Maybe we can do something instead, just you and me?"

"Maybe." I grunted.

"Let's go eat and we can talk about it then." She said, dragging me out the door.

The food helped to diminish my bad mood. We had a pleasant lunch. Indian food is one of my favorites. We talked for over an hour after we had finished. She told me about her classes and who her roommate was cheating on her boyfriend with. I confessed to hooking up with a couple of girls in my office this semester. I couldn't bring myself to tell her about yesterday yet. For some reason, she wasn't shocked, but thought that it was funny. I had to admit I had a lot of fun spending time with her. It had been quite some time since we had hung out for any kind of extended period of time. I enjoyed her company. She was smart and witty, with a maturity beyond her years.

I let Kelly talk me into taking her mini golfing. I won the first round, so naturally, we had to play again. As we played the second round, we ended up behind a large family of six or so. Two of the kids, both girls, probably 9 or 10 years old, were staring at us pretty much non-stop. After two holes, the dad offered to let us play through them. As we did, I heard the one little girl say to their mother "Mommy, they're on a date. I bet they're gonna make out!" The mother shushed her quickly and apologized. Kelly smiled big and knelt to whisper in the little girls' ear. The little girl covered her mouth with her hand and giggled. She ran to tell her sister whatever Kelly had said.

As we started the next hole, I stopped Kelly beside a bench. "What did you whisper to that little kid?"

"Woman stuff. You wouldn't understand." She said with a grin. Then she jumped up on the bench, stretched up as far as she could and kissed me on the cheek. I heard an 'Oooooh' and childish giggling come from behind us. Kelly laughed as she took her next shot.

We went back to the apartment and I ordered pizza. Kelly grabbed the remote and went through my Netflix queue.

"You know, you watch way too many boring-ass documentaries and titty movies. You're such a little nerd-boy."

"I prefer man-nerd, thank you very much," I retorted. "So, pick something you like instead."

"Don't worry, I am." She said flatly, as if there were no other option.

I brought some sodas and paper plates to the coffee table as she started the movie.

"I like this movie. The one blonde guy in it is super-hot," she quipped.

"Lovely" I replied with a mouth full of food.

"Don't worry, I made sure to find one that showed some boobies. I know how much you like them." She winked as she took a drink from her can.

"You'd be surprised," grinning as I said it.

"Uh huh. Now shut up," she replied and turned the volume up.

When I was full, I leaned back on the couch. Within minutes, Kelly had wiggled herself up against my side, her head on my chest once again. As the movie went on, she'd laugh and slap me on the leg periodically. Soon enough, there was a romantic scene. The blonde male lead pulled his shirt off and I heard Kelly make an audible 'Mmm' sound. She shifted around beside me and I couldn't help but laugh a little.

"What?" She asked indignantly.

"Nothing." I said, trying not to smile.

"Tell me." She pleaded.

"Well, it seems that I'm not the only one who likes seeing members of the opposite sex with their top halves unclothed." She smacked my thigh again.

"I told you he was hot. Look at those pecs!" She sounded so innocent somehow.

"It was just funny, as soon as he pulled his shirt off, you started squirming and purring."

"I did not." She smacked my leg harder this time.

"Oww. You did too. But, whatever, it's fine. I just thought it was funny." I rubbed my leg. That last one had stung.

"Well look, now she's got her tits out. I'm sure you'll have a boner here in a second."

"Just because of some TV boobs? No chance." I gestured at the TV screen. "Besides, those are way too big and fake. I already told you, I like boobs that are proportional to the rest of the body."

"Oh." She said quietly. "Right."

We watched the rest of the movie in silence. When it ended, the next show in the queue began to auto start. I saw that it was one of my documentary series. Expecting an objection, I looked down at my sister and saw that she was asleep. I watched the show in still silence, not wanting to disturb Kelly. When it ended, I set the remote on the end table and slid myself out from under her. I grabbed the blanket off the back of the couch again and covered her up. I had to force my eyes away from her shirt, which was now pulled snug across her chest, causing her hard nipples to poke into the thin fabric. I shook my head and chided myself for looking as I walked to my room. I stripped down and slid between the sheets. The cool friction shocked my cock awake.

I stared up at the dark ceiling. Why was I so turned on right now? Sure, I had been looking forward to my date with Pamela all week. I had seen my sister's butt and nipple by accident in the bathroom. Kelly had been teasing me about boobs off and on all day and was clearly turned on herself earlier. The way she was squirming on the couch, I knew her little pussy had gotten wet. Wait. Stop thinking about your sister's pussy, you sick creep. Fuck. Then I remembered her little nipples pointing up just minutes ago, begging to be sucked on. Double fuck. Now he's really hard.

I sighed and started to slowly stroke myself. Might as well get this over with so I can sleep. I reasoned. I tried to focus on Pamela's face and how amazing her plump ass looked in her yoga pants the last time I saw her around campus. I closed my eyes and suddenly in my mind I saw Kelly's cute ass in the reflection of the mirror earlier today. My dick throbbed harder, so I stroked myself faster. I started to pull the sheet away so I wouldn't get cum all over it, when I heard the doorknob wiggle. I froze, my hand wrapped around my throbbing cock, the thin sheet now barely concealing it, as Kelly opened the door. I could see her tiny silhouette in the light coming from the hall as she tiptoed through the doorway and into the bathroom.

I took a few deep breaths and tried to calm my heartbeat as it was pounding in my chest. Damn that was close. I was almost caught jacking off by my little sister. Another half a second, and I wouldn't have been covered up when she came in. I felt my cock throb at the thought. Speaking of covering up, I quickly pulled the sheet back up over my chest. As I did, the bathroom door opened again. Kelly tiptoed out and started to close the door behind her. She had taken her shorts off in the bathroom. All she had on now were some bikini cut panties and the thin green top. My cock pulsed.

"Good night sis" I said quietly.

"Oh shit! Jacks, you scared the Hell out of me!" she exclaimed, jumping back several feet. "I thought you were asleep"

"Almost," I replied, trying not to laugh.

"I had to pee." She stated, as if she needed an excuse to be in my room.

"It's ok. You're allowed."

She stood there a moment, hands on her hips, the faint light illuminating her tiny frame from behind the bedroom door. Without a word, she closed the door behind her. She paddled over to the bed and slid under the sheets next to me. Her skin felt nice against mine.
