You might say that things hadn't been going well for me.

First off, I had skipped out of a class one day to surprise my girlfriend with flowers, hoping she might be up for a little afternoon sex. She was, but unfortunately, she was having it with someone else, and I walked in on it.

With no way to afford an apartment on my own or any desire to return to dorm life, I moved back into my old room at home after that. I managed to keep up with my classes, but the depression that hit meant something had to give. I lost my job, which further limited my options.

As happened all too often, that muddle of the last few months was running through my head as I walked through the airport parking garage after dropping my parents off. They were going on a cruise, leaving me in charge of my eighteen-year-old sister, since I was on summer break from college.

And that was the next problem.

When I'd left home, Sunny was only fifteen, a little socially backward, and sometimes a nuisance. The very first day I was home, I found out that a lot had changed in the three years since.

As she walked a few feet in front of me through the garage, I caught my eyes straying to the sight of her butt swaying back and forth in a pair of tight shorts. She wasn't fifteen anymore, that's for sure. I'd had ample opportunity to notice that since she'd never grown out of running around the house in her underwear.

Not that the clothes she'd started wearing covered much more.

I tore my eyes away, thinking that I really needed to get laid. It had been three months since I'd caught my girl riding some other guy, and it was beginning to wear on me. I could try to chalk it up to pent-up cum, but the truth was that my little blonde sister Sunny had more than 'flowered' while I was gone. Not having had the advantage of watching it happen, the reality hit me hard.

We made it to the car a few seconds later, and I clicked the button on my key chain to unlock the door for her. She was waiting for me when I sat down behind the wheel. The sour expression she'd worn since leaving the house vanished.

"You're not really going to keep me on punishment, are you?" she sweetly asked.

"Don't even try it," I said as I put the keys in the ignition. "I promised Mom and Dad."

"Oh, come on. You did it."

"No, actually, I didn't. You were drinking and driving, Sis."

"I was only buzzed."

"How many people with their cars wrapped around telephone poles have said that? The ones who survived any way."

She sat back in the seat and sighed. "Okay, I know it was stupid - but gawd. They grounded me for like the whole summer, took my car and everything."

I chuckled as I put the car in reverse. "It's one month. You're getting off easy. They grounded me for three months the first time they caught me drinking, and I'd walked home."

"Can I at least get on Facebook? I feel like the whole world is passing me by."

"How are you going to get away with that? Mom and Dad are on your friends' list, and they're holding your car hostage."

Sunny's head thumped into the seat and she groaned. I think the reason Mom and Dad had bought us cars when we turned sixteen was for the sole purpose of using them as bludgeons to keep us in line. My sister loved that car, and she wasn't going to risk it.

"Suck it up," I told her. "The month's up when they get home. It's not going to kill you."

"Easy for you to say," she said as she turned on the radio.

I shook my head and concentrated on driving, since we were merging into traffic. A few glances her way revealed that my sister's expression had slipped back into a pout. I'd obviously been right about her trying to butter me up in hopes of some slack in her punishment.

Sunny went up to her room to mope for a while when we got home, so I took advantage of the solitude to watch the baseball game in the living room. It was nice to be able to kick back on the couch with a beer and relax for once.

I heard the top stair creak after an hour or so and glanced that way. I had to swallow hard as my sister bounced down the stairs in a bikini. Bounced doesn't even begin to describe what her perky breasts were doing in that barely-there top. I grabbed my beer and took a long pull as she reached the bottom of the stairs, and focused intently on the television in front of me.

A surprised grunt escaped me when a bottle of sun tan lotion plopped into my lap.

"Put some on my back for me," Sunny said as she stepped right in front of me.

Sitting on the couch, I was staring directly at her ass hanging out of her bikini bottom. The way the cloth hugged the perfect curves of her butt drew my eyes like a magnet. I didn't get to see it long, because she sat down on my knees a moment later.

Fighting an embarrassing rush of blood between my legs, I grabbed the bottle and squirted lotion on her back. That didn't help in the slightest when my brain changed the globs of white on her back into something far less innocent.

Though I was determined to get it done and over as quickly as possible, the feeling of her soft skin as I rubbed in the lotion made me want to linger. I clenched my teeth, wondering what the hell was wrong with me, and finished up by wiping my hands on my shorts.

Those shorts were decidedly tighter than they had been before she came downstairs.

"Thanks," Sunny said as she popped up and turned around. She bent over to grab the bottle of lotion, leaving me staring straight down her top for a few agonizing moments.

I groaned and let my head thump into the cushion behind me as soon as she was out of sight. I could feel my cheeks burning and prayed she hadn't noticed that - or that I'd gotten about half hard.

It was going to be a very long couple of weeks.


"Good morning, sleepyhead."

I started awake the next morning to my sister straddling my stomach and grinning at me. Still half asleep, the first thing my brain latched onto was her short nightshirt riding up to reveal just a sliver of pink panties resting against my skin.

"Get off," I grumbled, pushing on her legs.

She giggled and slid backwards. My eyes popped wide open when her butt bumped against my morning erection hidden beneath the sheet, but she swung her knee over me and hopped out of the bed a moment later.

"Come on, get up. I made you breakfast," she said while jerking the sheet.

I caught it just in time to avoid her revealing me in nothing but a pair of briefs.

"Okay. Okay. I'll be up in a minute, Sis. Get out of here."

"Hurry up before the coffee and pancakes get cold."

Sunny had already cleaned her plate by the time I got dressed and headed downstairs. She stood up and poured me a cup of coffee, which she brought over before going back for the pancakes.

"Sucking up isn't going to do any good," I warned her as I picked up my coffee.

"I'm not sucking up."

I chuckled and rolled my eyes. I couldn't hold back a satisfied groan as I sipped the coffee.

"Good?" she asked.

"Perfect," I admitted.

She brought over my pancakes and sat them down in front of me. She'd drizzled the syrup and placed the melting butter pats rather artfully on top.

"Enjoy. I'm going to go get dressed."

Thank god, I thought, because her nightshirt had the most eye-catching wrinkles stretching between her breasts.

My sister knew how to cook, and I was starving, so it didn't take long to polish off the pancakes. The shorts and tight t-shirt she'd changed into when she came back in to put the dishes in the dishwasher weren't that much of an improvement over her nightshirt.

"So are you going anywhere today?" she asked.

I lifted my eyebrows. "Why?"

"Just wondered."

"I'm not going anywhere. What are you up to?"

She looked at me and must have determined that I was serious. Then, she fixed me with puppy-dog eyes.

"Can I go to the beach? Just for a little while?"

I shook my head as I stood up. "I already told you that it's not going to do you any good to try to butter me up. I promised Mom and Dad that I'd keep you here and out of trouble."

"I'm not going to get into any trouble."

"Not here, you aren't."

"Fine," she sighed as she walked out of the kitchen. "You're no fun any more."

"Tell you what..." I began, thinking I might have found an out.

Her shoes actually squeaked on the floor when she came to a sudden stop.

"You prove to me that you understand how dumb it was to get in the car after you'd been drinking, and maybe I'll ease up."

"How am I supposed to do that?"

I looked back over my shoulder and said, "That's up to you."

Half expecting another fit of pique, I was pleasantly surprised to see her brow knit in thought instead.

"Think about it," I suggested. "That's really why you're grounded in the first place. You're supposed to be thinking about what you did."

"And you'll let me off punishment?"

"I didn't say that. I said I would ease up."

"Like what?"

"Let you have a friend or two over. Something like that."

She pursed her lips and nodded. "Okay."

"Good. Thanks for breakfast, by the way."

She beamed me a brilliant smile. "You're welcome."

She continued out into the front room, and I hoped she actually would think about it. My best friend had died in a drunk-driving accident when I was sixteen, and it had really shaken me up. That was the reason I'd made the promise to my parents, and why I intended to stick to it.

Once again finding my eyes drifting to her too-sexy behind as she walked away, I silently cursed myself. As little as I wanted to admit it, my sister was hot, and I couldn't help but notice. Even after she passed out of sight, I was still thinking about how good she looked.

A distraction was in order, and I had just the first-person shooter to provide it waiting in my room.


The house was quiet at about one in the morning. The day had gone a lot easier for me once Sunny left for her shift at work for the local supermarket. I knew she wasn't terribly happy about driving Mom's minivan there, but at least she hadn't complained about it this time.

I went out for a while, but ended up coming home when there was little to nothing going on. All the money I had was from selling off some of my old video games, and I had more important things to do with it than waste gas desperately seeking something to do.

With about eight beers in me, I was feeling mellow when I shut out the light and lay back in bed. The moon reflecting off the pool was creating wave patterns of light on the ceiling, making me wish I had a joint to go with my beer. My brain simply refused to shut down. It was like white noise of thought with no real coherent direction, and it was keeping me awake.

I jolted out of a half-doze with a momentary, panicky feeling of falling, and snorted in frustration. Stubbornly closing my eyes, I tried again once my heart stopped pounding.

I thought I had imagined it at first, but then I heard it again. I knew it was my sister's voice, but hearing it through the wall our rooms shared was positive confirmation. What I'd heard was a faint whimper, and it repeated again shortly after I realized what it was.

I wondered if she was having a nightmare, and briefly considered going to check up on her. The whimpers kept coming, sometimes joined by other, less discernable sounds. I tried to block them out and go to sleep, but it wasn't working.

The sounds slowly grew more frequent, and I started wide awake when I finally realized what they were.

My sister was masturbating just on the other side of the wall.

There was no stopping it. I instantly saw an image of her lying on her bed in my mind's eye. Her legs were parted and her fingers flashed over her pussy. She writhed and twitched in time with the moans and whimpers I could suddenly hear with near-perfect clarity.

My briefs tightened as I swelled to rock-hardness. My cock was virtually screaming at me for attention, and it was impossible to ignore. Giving in to the inevitable, I pushed my underwear down.

I stroked fast - the vision of her so real behind my closed eyes. I imagined her squeezing her perfect breasts and pinching the nipples that I'd seen poking at her tops so often since coming home. There was no need to imagine her sounds of pleasure growing louder, because they were very real.

Nearing the point of no-return, I heard the loudest sound yet filter through the wall. The long, sharp cry could only be my sister exploding into orgasm, and I was right behind her.

Over and over again, cum surged up my shaft and erupted to spatter on my chest and stomach. In my thoughts, Sunny was frozen with her back arched high and two fingers buried to the hilt in her little pink pussy.

Though I'd kept all but a choked-off grunt from escaping me as I came, I couldn't hold back a desperate gasp as the last spurt ended, replaced by oozing trickles that dribbled down onto my fingers.

I lay covered in cum with my cock clenched in my fist for quite some time.


"Are you mad at me?"

I winced at the sound of Sunny's voice emerging from the doorway, glad that I was facing away from her. Thoroughly ashamed by what I'd done the night before, I'd avoided her all day long.

"No. Why would I be mad at you?"

I was surprised that I managed to say it without stuttering or my voice cracking.

"I don't know. You act like you are."

"I'm just not in a good mood," I mumbled, still afraid to face her.

"Can I come in?"

I shrugged, keeping my eyes fixed on the computer and the mouse moving, though I had no real idea what I was doing.

Sunny sat down on the bed where I could see her in my peripheral vision. After a few seconds, she took a deep breath and let it out slowly.

"I've been thinking - like you told me to," she said in a soft voice.

"That's good."

She sat quietly for a few seconds, and then the words started spilling out of her. "It didn't make much sense to me at first. I mean, I know it was wrong and stupid, but ... I just didn't get what you wanted me to say. Then I was walking to the bathroom and saw that picture of you and Wes in that big collage Mom framed."

When I heard her sniffle, I turned to look and realized that she'd been crying.

"It hit me like a hammer or something. The only time I've ever seen you cry since you were little was at the funeral. It made me think about Sam and Wendy being in the car with me and ... and..."

Tears started streaming down her face, and I got up to sit down next to her. She buried her face in my shoulder and cried. I wrapped my arms around her and stroked her hair as she sobbed, until she leaned back with a shuddering sigh.

"I'm s-sorry," she said while looking into my eyes.

"It's okay," I said, and then wiped away a tear meandering down her cheek.

"I didn't think about who else I could have hurt, or how you and Mom and Dad would have felt, or anything. I'm so stupid."

I shook my head. "You're not stupid. You just made a mistake, and I think you get that now."

She nodded and sniffled.

"Feel better?"

She gave me a weak smile. "Sort of." Then she wiped her eyes and said, "God, I must look ugly."

"You're not even remotely ugly," I said before I could think better of it.

Her smile widened. "Thanks. I think I'm going to go lay down and take a nap."

It was only then that I realized I was still holding her. I unwrapped my arms from around her and nodded toward the door.

"Thank you, Greg," she said, and then leaned in to kiss my cheek before getting up from the bed.

I could feel the touch of her lips long after she left.


The emotional episode actually helped me deal with the physical attraction that had taken hold of me. When she woke up, I asked her if she wanted to call some friends to come over, since she'd fulfilled her part of the bargain.

She suggested racing me in Mario Kart instead.

We ended up playing video games for hours in a struggle to one-up each other. She even ordered a pizza so we wouldn't have to quit to make something to eat. We were both yawning by the time we put down the controllers and shut the console off. It was easily the best day I'd had in months.

Once she got out of the shower, I took my turn, even though I could have gone to Mom and Dad's bathroom at any time. I had just rinsed the shampoo out of my hair when I heard the door open.

"Sunny, what are you doing?" I asked as I dropped my hands between my legs to cover me, even though the shower curtain probably did the trick.

"I've got to tinkle," she said as she rushed past.

"So go to Mom and Dad's bathroom," I protested.

"Can't wait."

I stood there stunned with the water rushing down on me as I heard the tinkle. Though I couldn't really see more than a hazy silhouette through the curtain, my imagination once again took over. She was sitting there with her panties around her ankles, not a foot away from me, stark naked in the shower.

Even her sigh of relief sounded vaguely sexual to me.

Thankfully, we have good pipes, so when she flushed the toilet, I didn't get hit with a lava-hot burst. I couldn't help watching when she pulled up her panties as she stood. I couldn't see much else, but she was wearing dark colored panties, so they stood out against her fair skin and light-colored nightshirt in the cloudy image of the room.

"Okay, now get out of here," I said.

Sunny laughed as she walked past, and I relaxed as I heard the bathroom door open.

She fooled me. I cried out in alarm when she jerked the shower curtain back a few inches and exclaimed, "Boo!"

"Sunny!" I yelled after her as she ran giggling from the room, leaving the door wide open.

She'd retreated to her room and closed the door, so I let it go. After checking my mail and Facebook, I hit the bed, but I couldn't sleep.

I knew exactly what the problem was this time. Even though my ears were warm, I was also about half hard as I lay there staring at the dancing reflections on the ceiling. Half of me wanted to stay awake until the wee hours to see if there would be a repeat of the previous night, while the other half was busy scolding me for thinking about it.

I heard the very first moan this time.

I sighed as my cock rapidly stiffened to the sweet melody of my sister's voice. She didn't seem to be holding back as much, which meant that it was all the clearer, and even more difficult to resist the temptation. I struggled with the lust boiling up in me for a few seconds, but it was a foregone conclusion.

The truth was that I'd known that, because I'd left a shirt within easy reach on the nightstand. Even if she hadn't played with herself that night, I knew I was going to, and I really didn't want to deal with such a messy cleanup afterwards. I slipped my erection into the tail of the shirt and wrapped my hand around it.

Taking it easy, I stroked my cock with the cloth, listening to her moan and letting my imagination run free. When I heard her building toward a crescendo, I picked up the pace. The cloth rasped over my cock, building the wicked itch in the tip. When I heard her come, I erupted just as hard as I had the night before.

This time, the fantasy ended with my cum spattering all over her beautiful body, and there was a smile on my face.


"So, do you want to call some friends, or would you rather get whooped at Mario Kart some more?" I asked after Sunny got home from her early shift at work the next day. I cracked open a beer and took a long drink.

"There's something else I'd rather do."

"What's that? Nothing too crazy."

She put her hands behind her and swayed back in forth in a positively stunning - and obviously false - display of innocence. She then nodded toward my beer and asked, "Can I have one of those?"

I coughed as my second drink tried to go down the wrong pipe. "Are you serious?" I sputtered. "That's what you got in trouble for in the first place."

She shook her head. "No, I got in trouble for driving. You know Mom and Dad were letting me drink here at the house."

After struggling with trying to keep me from drinking, they'd decided to try a different approach with my sister - acceptance that it was going to happen, but only allowing it on their terms.

"Were is the operative word there. Think you blew that."

"Come on. Please? My boss was being such a bitch today. I just want to..." She trailed off and let out a frustrated growl. "I'm not going anywhere. I'll be right here with you so you can keep me out of trouble."

I crumbled under the pressure of her batting her eyelashes at me. "I ... Okay, but only a few, only today, and if you tell Mom and Dad, I'll kill you."

She let out a whoop of excitement and bounded off to the kitchen. A minute later, she plopped down on the couch next to me and popped open the can. The moan she let out after the first drink sent chills up and down my spine.

"Oh, that's so good. Thank you. Thank you. Thank you."

I laughed and shook my head. "So, do you want to watch a movie or something?"
