Sis

I woke up early in the morning, feeling my morning wood. This was quite normal, and I reached underneath me to wrap my fingers around the shaft. I wasn't awake enough to seriously masturbate, just a sleepy, slow, enjoyable squeeze.

I rolled a little onto my side so that my prick wasn't pushing into the mattress. I could now stroke it easier, and as time went on my stroking started increasing. What I didn't know was that my sister was standing in the doorway watching me.

She watched as I squeezed the base of my penis, then slowly let my fingers push up toward the head. I moaned, pushing my hips forward, and rolled onto my back.

My erection was now sticking straight up into the air, and I was wide awake. My eyes hadn't yet opened, but my hand started stroking my dick from base to tip. I grabbed the base with my hand and wiggled it from side to side, slapping both of my legs with my dick, while I had some particularly nasty thoughts about the sexiest female in the bar last night. Moaning again, I pictured her hand, not mine, attacking my woodie.

My knees bent as my legs raised up and spread. My non-pumping hand reached between then and grabbed my balls, pulling them down gently. This gave my sister a perfect view from my door, and her eyes were bugging out.

My fingers squeezed my cock head, pre-cum covering it. I smeared the fluid over the head and down the shaft, and my hand started flying up and down the wet shaft. My hips started moving and I started moaning, quietly, so nobody in the house would hear me. I still didn't know my sister was in my doorway.

The sexy vision in my head was naked and attacking me, and my hand was helping to bring about my orgasm quickly. I reached one hand over towards my night table to grab a tissue, but before I could find it my cum started up my shaft and spurted out high into the air. It was on about the third spurt that I realized I had heard an unusual noise. Probably a couple more spurts shot out before I managed to force my eyes open and look towards the noise. I was shocked to see my sister standing there. Her eyes were fixed on my cock, and I'm not sure if her eyes or her mouth were open wider. She was totally stunned.

As my cum finished oozing out, I yelled - well, whispered loudly - "What are you doing?"

Jamie's eyes shot up to look at mine, surprised that I knew she was there. Her eyes went back to my dick, then back and forth from there to my eyes a couple of times before she turned and ran into her room, closing her door.

I was also in shock, but the most important thing was to clean up my mess. My orgasm had happened so quickly it had shot out all over me. I would have to deal with Jamie later.

I had recently moved back home. It was just temporary. I had to move out of my apartment. I had a new one but couldn't move in for three months. I thought it was easier - and cheaper - to move back in with my parents instead of bunking with a friend, even if I was 22 years old. I had a lot more room, too. But I had to remember to think about some of my habits, like sleeping in the nude and leaving my door open.

My sister had graduated from high school, but hadn't yet decided what direction her life was going to take. I thought she was trying to wait and marry some rich dude so she wouldn't have to work, ever. She denied that, but I hadn't yet seen any signs that she was looking for work. She was nearing her 19th birthday and had never had a job yet.

She certainly had the body to snare a rich dude. 5 feet 6 iinches tall, brunette hair worn very long, a thin body with shapely hips and above average boobs. She was very good looking, and a very pleasant personality and smile that she had only because she never had any responsibilities. Well, that's from a big brother's perspective, anyway.

Jamie avoided me most of the day, but that afternoon I walked past her open door and saw her there. I decided to confront her.

"Hey, Jamie. Have a minute?"

"Uh, okay." she replied, tentatively.

"I was wondering why you were spying on me this morning," I said, sitting down beside her on her bed.

"Spying on you?" she nearly screamed. "I wasn't spying. I was just walking past."

"And decided to stop and watch."

"Well, yeah. It surprised me."

"How long were you watching?" I asked.

"Ahhh, before you rolled onto your back."

"What?" I was surprised. "You watched me the whole time?"

"I don't know. A while," she answered. "Why were you doing that anyhow?"

"Doing what?" I was defensive now. "I couldn't help it, I just woke up that way. It's normal. There's nothing wrong with it."

"Does everybody do that?" she asked.

"Yeah, I imagine. If you mean guys."

"Of course I mean guys. Girls don't do that!"

"Girls don't masturbate?" I asked. "Or girls don't wake up with an erection?"

Jamie blushed at the use of my language. Or at the whole conversation. "Do you do that every day?" she asked shyly.

"No," I answered. "sometimes in the morning, sometimes later in the day." I paused while she seemed to be thinking about that. "Sometimes more than once."

That got her attention and her eyes ahot back up to meet mine. "More than once?"

I nodded.

"In one day?" She seemed surprised.

I nodded again.

After a minute of thinking, she looked at me and asked, "You mean you could do it again? Like now?"

"Now?" I asked. "Yeah, I guess. I mean sure."

She looked for a minute more, then said, "Show me."

I didn't understand what she meant. "How can I do that? You'll have to take my word for it."

She hesitated again. It seemed she was having trouble talking for a change.

"Not if you do it here," she said so quietly I almost didn't hear her.

"Here?" I asked. "Here?" I asked again. "You mean..." I didn't know how to finish that sentence.

"You could do it again. Here," she said. "I mean, I already saw you do it. I was just too shocked to, you know,"

"Enjoy it?" I finished for her.

"Well, maybe, I don't know. But I'd be interested in seeing it again."

"You want to see me masturbate?" I was finally understanding her.

"Again," she reminded me.

"Why?"

"Well, you're a guy. I'm interested in guys. And how they work."

I laughed to myself. But then I thought out loud, "What do I get out of it?"

"What do you want?"

I thought a minute. "You saw me, so I get to see you. Nude."

"No way!" she said. After considering for a minute, she said, "How about topless?"

"Deal," I said, perhaps too quickly. I was excited at the possibility of seeing her tits. I had admired them for a good while.

"Go ahead," she said impatiently.

"Now?" I asked.

"Why not?"

"Well, you first. You said topless." Maybe that would slow her down while I considered this.

She didn't hesitate long. Her arms crossed at her waist, grabbing hold of the bottom of her shirt, and pulled it up and off. She looked very sexy with her breasts being held inside a lacy little pink bra. I stared at her for a minute but said nothing. She finally reached around behind her back and unclasped her bra. It hung loosely, clinging to her mounds. With a shrug of her shoulders the straps came off her shoulders and she pulled the cups down, exposing her gorgeous tits. Her aureoles and nipples were about the sexiest I had seen.

It wasn't until then that I noticed my erection straining painfully against my pants. Jamie noticed too. "Your turn," she said, looking at my lap.

I have to admit that I wanted to do this. I hadn't at first, but now it was a little thrilling to be exposing myself. I am a little bit of an exhibitionist, I guess. I opened my pants and pulled them off, with my boxers. My erection sprang out, bouncing in front of me, causing Jamie to giggle.

I took hold of my erection, but was staring at her tits. She shifted around a little on her bed for a better view, causing her tits to bounce. Fantastic!

I began stroking my cock slowly as Jamie watched intently. I rubbed my finger around the head, the slit, showcasing different parts of the shaft as Jamie took it all in. I went back to staring at her tits. They called out to me, and without realizing it my other hand reached out and cupped one of her tits.

To my surprise, Jamie acted like she didn't even notice. She kept watching my stroking, and my cock was getting more engorged. I was squeezing her tit, playing with her nipple, paying more attention to it than my erection. My hand was now just on automatic, going up and down the shaft, but Jamie was watching intently.

"That feels good," she said, glancing at me.

I thought she meant my dick until I realized that she didn't know how that felt. Did she mean me playing with her tit? I tried an experiment by pinching her nipple, which caused her to moan and smile. "Mmmmm," she said.

She leaned forward. I was shocked when I I felt her finger on the tip of my cock. I looked at her to see what was going on, but she was concentrating on my cock. Her fingers spread over the head, stroking it gently. Then her fingers started down the shaft, feeling the ridge around the head and the one running down the underside. When her fingertips reached around the shaft, I stopped stroking. Her fingers clasped tightly around the shaft, then moved up slowly and gently, then back down. She did it again, this time a little further, and it was my turn to moan.

She glanced up at me and smiled, then returned her attention to my cock. She stroked it from base to head, and squeezed it harder. Her thumb pressed on the tip. Her fingers moved up and over the head, going over it lightly several times. Her other hand reached down and held my nuts, moving them around, playing with them, examining them.

I had not lost interest in her tit, but it was increasingly hard to not focus just on my penis. It was increasingly hard as well, and I couldn't take much more.

"I'm going to cum," I warned.

"I want to watch it," Jamie said. "What should I do?"

"Just keep pumping," I said with difficulty. "Like that." I reached my hand down to hers, placing mine on top, and assisted her pumping. In just a minute I was shouting, "Here it comes."

I pushed my hips up as cum spurted out. Jamie gasped and watched intently. I kept her hand stroking my cock, and squeezed tight as we milked all of the juice out of the shaft.

"Fuck, that was great!" Jamie said.

"Did you like that?" I asked. "Is that what you wanted?"

"Yeah," she said dreamily. "That was just what I wanted to see."

She looked at the clock. "We better get cleaned up. They'll be home soon."

She was referring to our parents, who had regular 9 to 5 jobs. I worked as a bartender, from dinner time to 2 a.m., usually. Jamie, of course, did nothing.

The next morning I was awakened with an odd feeling. It was mid-morning, as usual, sleeping later than the rest of the family since I got home so late. The parents had long since gone to work. But I felt something. Something on my ... penis.

"Oh," I moaned. My dick was getting stroked. I was wide awake now, and realized that Jamie was stroking my dick. I was on my side and she was kneeling on the floor beside my bed, stroking my erection with both hands.

"Good morning," she said.

"Mmmm," was all I could reply.

Jamie had one hand wrapped around my base, and the other stroking the top half, up and over the head, exciting the tip as she went. I really started moaning, and my cock become thicker as it became engorged with blood.

"Are you going to cum?" she asked.

"Yes. Yes," I said.

Both of her hands now began stroking my shaft, both at once, squeezing harder, pumping faster, harder, tighter, as if forcing my cum out. And out it came, spurt after spurt, and either by design or accident it shot onto the mattress, making a long oval puddle between us.

As Jamie milked the last of my cum out of my dick, I regained my senses. "Thanks. What a way to wake up."

"Maybe I'll do that more often."

"Shit," I replied. "Now I'll go to sleep with a hard on, too."

She giggled. "I don't think I dare come in then, when Mom and Dad are here."

I looked at the puddle. "Now I have to change my sheets. I use those tissues there," I said, nodding toward the box. "Or you could use your tongue."

"EWWW!" she said. "My friends have talked about that. I'm not sure I would like that."

"Not sure? Have you ever tasted it?" I asked.

"EWWW, NO!"

"You said didn't know if you'd like it," I reminded her. "Now is your chance to find out."

When she didn't say anything, I thought I would try something. I stuck my finger in the puddle of my cum, then held it up right in front of her mouth. "Try it?" Yes, it was a question. Sort of.

Jamie hesitated. For so long I was about to give up. Just before I went to move my finger away, she opened her mouth slightly. Her tongue came out and slowly licked some cum off my finger.

"It doesn't...really... taste like...much," she said.

"Try it again." I took hold of my limp dick at the base and moved it toward her a little. "Try it from the source," I smiled.

She looked at me. questioningly, and I thought I had gone too far. She reached a finger slowly toward my dick. She reached one finger out and slid it over my cock head, getting some cum on it.

As she licked my cum off her finger I wiggled my dick toward her again. "Don't use your fingers." I just couldn't help seeing how far I could push it.

She looked up and her eyes got big. She started to say something. Or maybe she was licking her lips. No, doubtful. But she moved her head toward my crotch. Her mouth came open slightly, her tongue slipped out, and then it touched my cock. A spark shot through me and I groaned. She looked at me again, with a slight hint of a smile. She licked out again, this time licking more. She tasted it and looked at me.

"It still doesn't taste like much at all," she said. "Even from the source," she added with a glint in her eye at her joke.

"There's more," I replied, hoping this would go on. My dick was beginning to stir.

She leaned in again with her tongue on her lips.

I issued another challenge, hoping I wasn't going too far. "Take the whole thing in your mouth." Her look didn't tell me if she was intrigued or turned off. "That gets the best taste."

I waited for a moment that seemed like minutes, before her head moved toward my dick once again. Her mouth opened, then my cock head disappeared into it. My deep groan told her how much I enjoyed it.

"Shit," I said.

She smiled around my dick. Her tongue licked the head inside her mouth, and she took another inch or two inside her mouth.

"AHHHH!" Damn that felt good. I also noticed I was getting stiffer.

Jamie took my dick out of her mouth and said, "It's getting bigger!"

"It'll do that if it's in your mouth," I told her.

She smiled and took it back into her mouth, a little deeper this time.

"AHHHH!" I said again. "Damn! Now move your tongue. Lick it inside your mouth. Suck on it. AHHHH! FUCK!" She followed directions and it was driving me wild. I put my hand behind her head and held her tight while I started to move my hips forward just a bit, fucking her mouth. I was trying to be gentle. "My God, Jamie, that's fantastic!"

My erection was returning, almost fully erect now, and she kept sucking and licking. Jamie took hold of the base with one hand, then pulled her mouth off.

"God, it's so great to feel it grow bigger. Really cool!" Her eyes were big, she smiled, then went back to sucking on my erection.

"Oh, hell, Jamie, it feels so good. If you do that much more I'm going to cum again."

Jamie seemed to smile around my dick. She sucked more as I started fucking her face again. I couldn't help it, but I hoped I wasn't too forceful. She seemed to be okay so far. She still had a hand squeezing the base of my cock, and I felt her other hand grab my balls. She dug her fingertips in at the top of my sack and pulled down.

"FUCK!" I yelled. "Oh shit! I'm going to cum. Jamie, pull off, I'm going to cum!"

She said something, but all it sounded like was a hum. I told her again to get off, I was going to cum, but she didn't. As I felt the cum churning up from my balls, I shoved my cock deeper into her mouth. I held her head tight as I shot my load deep into my sister's throat. I shoved in three times before I could control myself enough not to push any more. I still spurted, and Jamie didn't remove her mouth until I was completely done. I was afraid to look at her. Had I done too much?

I finally did look at her, and she was looking up at me. She had a big smile on her face, and a big load of cum dripping down her chin. She looked back at my cock as her hand coaxed a little more sperm out of the head, and she leaned over to lick it. I moaned again.

"Did you like that?"

"Holy shit," I said. "You were fucking fantastic. You've had some practice doing that."

"No, never," she said. "But I'm going to. I really like that. I LOVED feeling your dick grow in my hand. And my mouth." She blushed a little as she said this last. "And you spurting in my mouth - awesome! Jeez. There was so much cum. It didn't taste bad, but there was so much of it!'

I just smiled, laughing inside. What a sister! What a slut! Just yesterday she was almost innocent. At least about as innocent as an almost nineteen year old can be. And now she was acting and talking like a real slut. And I was benefitting from it all. And it seemed like it would continue.
