AUTHOR NOTE: I have had a couple comments criticizing how I sometimes strings letters together to show that someone is moaning. While I do appreciate feedback, I am honestly not looking for people to tell me how to write. It's ok if you aren't a fan, I'm not offended! Please know that when I string a bunch of "nonsense" letters together, I am not just jamming keys on my keyboard. I very deliberately type out each letter, trying to capture what I imagine the moan sounds like. If I put a lot of the same letters in a row, or make them all caps, it's my way of trying to convey that the person is moaning longer (and potentially louder) than usual. Because it feels so good, you know? Anyway, I just wanted to mention this. If this isn't your style, I don't mind if you don't read my stories.

STORY:

PART I.

Over the next two weeks, things seemed to get more convoluted at the same rate that my guilt grew. And the messed up part was that my guilt was a tripled-edged sword. I felt guilt toward my wife for what I had done with my sister. That betrayal was immense and the secret was killing me. I felt guilt toward my sister for sleeping with my wife. That one baffled me at first, but I couldn't deny it. Some part of me had unwittingly committed itself to my sister, as if we were supposed to be in a monogamous relationship.

And then comes the third edge of the sword. I felt guilt for being attracted to my own flesh and blood. My sister. And I had acted on those attractions, multiple times. Maybe at first it had been more of me "giving in" to her advances. But I couldn't deny how much I enjoyed it. How much I enjoyed her company. Touching her. Hugging her. Being touched by her. And especially making love to her. Despite the fact that we had only slept together that one time, right before my wedding, there was something to be said about fantasizing about her while I fucked my wife.

After the first time I thought about my sister while I plowed my cock into Wendy's pussy, I couldn't stop doing it. In fact, I stopped fighting it altogether. My wife seemed to enjoy it. Thoroughly. It was intense for me, so I knew it was intense for her. But the more I did it, the more addicted to it I felt. Over those next two weeks, I made love to my wife nearly a dozen times.

Betraying my sister seemed to be the ever growing skeleton in my closet, though. The more I had sex with my wife, the more I felt like I was jabbing a knife in Shelly's back. It was really backwards and fucked up, I knew. But I couldn't shake the emotion.

During those first weeks, something else was happening, too. Shelly had always been flirtatious with me, for years. But somehow, her flirts seemed to be growing more intense. It was like she cranked the volume on her seduction. It was way more than just secretive little looks or smiles. She touched me frequently. She would drag her hand across my crotch when she passed me in the hall. Or purposely have the bathroom door open while she climbed out of the shower, letting me see her naked body. That one had made me stumble past the doorway. When I made love to Wendy later that day, Shelly's tits were all I could think about. I didn't last long that time.

I very deliberately didn't make any advances back toward my sister. As much guilt as I felt toward her, I still felt wrong about it. Wrong about pursuing a relationship with my own family member. Christ, she was barely an adult! Even though she was nineteen, my parents still treated her like she was a kid. Sometimes I guess even I still saw her as a kid, being my "little sister" and all. It was a hot mess, to be sure.

This leads me to another incident. One I don't even know how I could have avoided. It was just over two weeks since the night when Shelly had come to sleep in bed with me and my wife. It was a Saturday morning and I had just made my way to the bathroom and hopped in the shower. The hot water felt good, and for a short time, I let my problems drip away from me like water going down the drain.

I didn't hear the door open a few minutes later. In fact, I was so relaxed from the hot water pouring down my body, I didn't hear a thing until the shower door opened suddenly and my beautiful, very naked, nineteen-year-old sister stepped in with me. She closed the door quickly behind her to keep the steamy air inside.

"Shit, Shelly! What are you doing??" I cried out in a strangled voice. My eyes darted toward the bathroom door, but I could barely see through the steam-covered glass panels of our shower.

"Relax," she said, smirking at me. My eyes couldn't help but take in her naked chest. Her breasts were glistening from the steam and I noticed that both of her nipples were sticking out, pert and erect. God damn she had perfect tits. "Mom and dad just went to the grocery store, and Wendy went with them." Swallowing, but still unable to lift my gaze from her generous bosom, she added cheerily, "It's just us two!"

Finally, I managed to get my eyes to lift up to her face. She still wore a grin on her lips. She looked excited, not embarrassed at all to be standing naked in front of her brother. I realized that my body was heating up beyond what the water was doing. With a start, I felt a tingle in my cock and when I glanced down, it was starting to stick straight out before me. Shelly giggled, and when I glanced at her face, I saw that her gaze had followed mine. She was staring at my boner.

"Is that for me?" she asked mischievously.

Swallowing, I shook my head. "Uh, it's because of you, but it's not exactly... for you."

My sister pouted. "Are you sure?" she teased. "'Cuz is looks like it would fit nice and snug in my mouth."

"SHELLY!" I cried her name. Jesus Christ. This had to stop.

"What?" she said innocently. Then she lowered her voice, looking down at my penis once more and muttering, "I'm just sayin'."

Struggling to control my breathing, I started drawing in deep breaths. The steam filled my lungs with each inhale. Just then, I saw something falling to the floor. It was a bar of soap from the corner shelf. Shelly slowly pulled her hand away from the shelf and followed the soap until it landed on the shower floor. "Oops," she whispered. "Silly me."

As I stared, I watched my sister slowly bend over. She turned slightly, displaying her ass for me. I almost groaned. Of course she would have a perfect ass, too. It was somehow a cross between being fleshy and being tone. The skin curved gently in a rounded fashion on the back, curving in toward the crack down the middle, yet the sides were somewhat flat. It looked very grabbable. And the way it shone from the steam that hung everywhere in the shower, made it look very tender and soft. Slowly, she squatted down, looking like she was reaching for the soap. At the last moment, she fell forward, landing on her knees.

Staring down at the beautiful, naked princess kneeling before me, I couldn't help but admire just how gorgeous she was. Her breasts hung perfectly, barely sagging against her chest. They were filled with a buoyant life of their own, moving ever so slightly as she wiped water from her eyes. She had her legs folded and was sitting on her heels as she looked up at me. The curves of my sister's body were accentuated by her position, and everything about her screamed beauty. Tilting her head back, she blinked up at me as water splashed against her forehead. She had positioned herself right in the main stream of shower water. From my vantage, her eyelashes looked longer than ever. Several tiny droplets of water clung to the tips of them. Every time she blinked, the droplets disappeared, merging into the stream of water cascading down her cheeks.

I was completely smitten, standing above the angelic little creature kneeling in my shower. Her brown hair looked almost black from the water. She had it slicked back over her head. When she reached a hand out toward my cock, I couldn't muster even a sliver of protest. I just stood there, watching the scene unfold before me. Her little fingers wrapped gently around my shaft and I didn't flinch. I didn't pull away. I think I gasped as pulses of pleasure wended their way up into my pelvis.

Shelly began stroking me, staring up at my face. She was still smiling, but it was more seductive than it had been. She lifted an eyebrow as she stared at me, as if questioning whether I was going to make her stop. When I didn't, her smile grew somehow more seductive. As I watched my sister continue stroking me, she slowly lowered her head until she was staring at my cock. Reaching her other hand up, she wrapped those fingers around it as well.

My sister had a strange look on her face. I had never seen someone gaze at my cock like that before. As her little hands slowly stroked my shaft, her eyes never blinked. She looked like she was trembling as she held it, almost reverently. Her eyes were wide, expression intent. It wasn't exactly curiosity that was painted on her face. It was something more. Infatuation? No. It was... it was rapture. My sister looked rapturous. Her eyes seemed to shine.

Suddenly, Shelly tilted her head slightly to the right and slowed her stroking. She eyed my penis as her hands slid down along it until I felt her pressing against my pelvis. Her fingers overlapped each other and several inches of cock protruded past her palms, pointing toward her face. She held still, staring. She breathed in through her nose, slowly inhaling until her lungs seemed full.

Then my sister leaned forward and opened her lips as she quickly took half of my cock in her mouth. My eyes sprang wide open and I moaned loudly, a sound that reverberated off the glass walls of the shower. My sister's tongue was already attacking my cock. She held it firmly inside her mouth with her lips clamped tightly around it, yet somehow they seemed to writhe against its surface. When she began to move her head, the pleasure was already beyond my imagination. Somehow, she kept tickling the underside of my cock with her tongue while she plunged herself slowly forward and back.

It was a scene from a fantasy as I stared down at my little sister's naked body, kneeling before me in the shower. Her cheeks puffed out as she took the length of my cock into her mouth over and over again. Her eyes were closed and her face seemed to beam with the rapture I had seen just moments before she took me in. Water sluiced its way down my body, spilling down my sister's face. She didn't seem to care. I felt her lips wiggling as she pushed them forward and back. Pinpricks of pleasure exploded in my cock. Her hands were still locked around the base of my shaft, holding it still while she worked her oral magic on the middle and tip.

Shelly was making slurping noises while she worked. I knew it was partly because of the water that was splashing around her lips. But it had a certain fervor to it. She sounded almost... hungry. That fact made it all the more arousing and erotic for me to not only watch, but experience. Water started pooling around her hands and I noticed it splashing up underneath her nose. She twisted her head, trying to inhale from the side. With effort, I reached behind myself and turned the shower faucet to the right until it shut off.

The room suddenly went from noisy shower to an empty, echoey room. I could hear water dripping, but mainly it was the sounds of my sister's slurping that were intensified. I realized I could hear her swallowing, too. Her tongue batted at the bottom of my cock, tickling the sensitive tip. Pleasure filled me. My cock felt hot, tingly and taut. I could feel her cheeks whenever she pressed forward. With her hands still wrapped around the base of my cock, I wasn't quite reaching the back of her throat. But that just gave her more opportunity to use her tongue. Truly, my sister was pleasuring me orally in ways I had never felt before. How on earth had she gotten so good at this?

Gazing down at my sister's teenage body, I had a moment of clarity. There was something intense about what she was doing. And it wasn't just physical. That look of rapture I had seen in her eyes while she stared at my cock... that wasn't just my imagination. And I realized, as I watched, listened and felt her pleasuring my cock with her mouth, that I felt that rapture, too. I was completely infatuated with my little sister. I would do anything for her. I knew it from the deepest depths of my heart.

An emotion sprang up inside me at my own revelation. Suddenly, the physical sensations of what was happening to my cock caught up to the rest of me. The noises my sister was making while she devoured my penis were driving me crazy with desire. The way her lips moved, wriggling their way almost sideways across my cock even while she plunged forward and back. And her tongue. Oh god, her tongue...

I was about to cum. I wanted to cum. I desperately wanted to fill my sister's mouth with my thick, juicy white milk, but I didn't know if she could handle it. I decided to warn her so I moaned, "I'm close."

At my words, my sister sucked in air sharply through her nose. And suddenly, it was like a whirlwind had been unleashed around my cock. Her hands started moving, in time with her head movements. She grew more intense in a heartbeat. I felt her lips clamp down and her tongue slid up onto the side of my cock while she plunged her head forward and back. Dropping one hand down, she squeezed my leg to steady herself. With her other hand, she jacked me.

Shelly's head tipped back a little and I felt her pushing more vigorously. My cock started going a little deeper into her mouth. I groaned, feeling myself start to sway with dizziness. Then my little sister began to whimper.

"Mm hmm. Mmm hmmm. Mmmm hmmmm. Mmmmmmmmmmmm," she made these little mewling noises. I realized she was encouraging me. She was whimpering for me to cum. Begging for me to finish and empty my load into her mouth. Oh god she wanted it so bad.

I couldn't hold on. I didn't even try to prolong it. With a bellow, my hips lurched forward and I felt my cock push deeper into Shelly's mouth than she had taken it on her own. Her head flinched, but then she was whimpering again, "Mmmm hmmm. Hmm. Mmm hmmmm. MMMM HMMMMM MMM HMMMMMM!"

"Gaaauhhnnnnnnnnnnnnnnnnnnnn!!" I cried out as I felt an intensely strong stream of cum shoot up my cock, exploding from the tip.

My sister let go of my cock with her hand so suddenly that I felt myself slide another few inches into her mouth, mid-stream. She immediately raised both of her hands to my hips and then back around onto my butt where she squeezed me hard, holding on. Still staring down at her, I could barely see any of my cock protruding from her mouth. I was buried in her mouth. She had her eyes squeezed even tighter and her face looked strained. But she held me. She held my cock while the head of it brushed the back of her throat.

Torrent after torrent of cum erupted from me. The scene, the sensations, the mood, my sister's rapture... it all built itself up in my mind as an otherworldly fantasy. And the pleasure was beyond words. Beyond intense. Beyond anything I had ever thought about, let alone experienced. Every orgasm with my little sister seemed to get more intense. More extreme. And this bathroom blowjob was no exception.

****************

It felt like hours went by while I filled my sister's mouth with cum. And she held on relentlessly until not a drop of cum still spilled from my cock. Toward the end, I felt pressure as she started sucking. She managed to pull another squirt of cum out of me, but then I was spent. By a million miles, I was drained. When she finally pulled her lips off of me, I felt so dizzy, I immediately sat down on the floor of the shower.

My sister wasn't saying anything. Her lips were clamped shut and her head was tilted back just slightly. I realized she must have a mass of cum in her mouth. Maybe she didn't like the taste and was considering spitting it out. Frowning, I lifted a hand--

Shelly swallowed. Hard. Then she swallowed again, her eyes fluttering closed. On her third swallow, a smile spread across her lips once more. And after three more, she tilted her head back down and opened her eyes, staring at me. She looked... happy. "Yum," she whispered. All I could do was blink at her. She tilted her head sideways a little and then said softly, "That was fun."

I nodded at her. I couldn't speak, but I could nod. My mind was a literal mess. I couldn't stop thinking about how fucking intense that had been. And that moment toward the end... that emotion I had felt toward my sister. God, she did things to me that I had never experienced before. She turned me on in ways that I had never felt from my wife.

What the fuck was I supposed to do?

PART II.

My life seemed to be a waking dream. Although at times, it felt more like a nightmare. I couldn't stop thinking about all the betrayals I was committing. My wife continued to demand near-daily sexual romps in bed at night, and I continued to fantasize that it was my sister I was fucking, which made the whole experience intense beyond words. At the same time, Shelly kept shooting knowing glances my way. She looked at me so often, I started to worry that people would notice. When our gazes locked, there was no question anymore as to what she was thinking about behind those gorgeous brown eyes of hers.

She wanted me. And, admittedly, I wanted her. It was a hot mess.

It had been just over a week since the morning when my sister attacked me in the shower, giving me the most profound blowjob of my life. I thought about it constantly. My wife even blew me a few nights ago, and as soon as I started replaying the shower scene with my sister, I exploded so hard in my wife's mouth that cum squirted out of her nose. Somehow that was funny to her, once she got herself cleaned up a bit.

Today was Saturday. Five weeks since my wedding night. When I woke that morning, my bed was empty. For some reason, I felt panicked about that, so I quickly went in search of my wife. I soon discovered a note from her that informed me she had gone shopping with my parents again. She didn't note when they had left. Frowning at the clock, I saw that it was just after nine in the morning.

After making myself a cup of coffee, I suddenly wondered where my sister was. Had she gone with them? Probably. The house was so quiet, I was sure I was alone. Deciding to make sure nobody was home, I started snooping. My parents' car was gone, so they were definitely out. And based on my wife's note, she was too. So that left only Shelly's bedroom.

When I reached my sister's door, I don't even know why but I opened the door without knocking. And everything froze in my universe, my eyes opening wide as I took in the scene.

Shelly was lying in her bed, leaning back against her headboard. She was wearing a white, cropped t-shirt with open sleeves and a pair of pink panties. That was all. Had that been the only shock upon entering, I probably would have reacted differently. But as it was, I found myself staring at my sister's crotch where she had a hand stuffed inside her panties, vigorously going to town on herself. Her other arm was on her chest, hand hidden beneath her shirt while she worked one of her nipples. The other nipple was hard, showing through the fabric of her shirt.
