Prenuptial Relations

SUMMARY: This is the third chapter of the story about an older brother and his teenage sister having sex days before his wedding day. This chapter picks up right where chapter two left off. As the guilt builds for the main character, so do his feelings toward his sister. But more importantly, his sister drops a bombshell on him that he must come to terms with. Also, there are a few hidden "foreshadows" in this story which hint about the next (and probably final) chapter of this story. Have fun trying to figure them out!

All characters in this story are 18 or older.

STORY:

PART I.

After the blowjob in my car where I nearly killed my sister (not really), my emotions were wrecked. Well, they probably had been wrecked even before that day. They seemed to go from one extreme to the next at any given moment. From complete and utter disgust with myself for all the things we seemed to keep doing with each other, to total infatuation and elation when I thought about her. One thing was common throughout all of my emotional states, though. I simply could not stop thinking about Shelly. No matter what I was doing or who I was with. She was a constant beacon in my head, pulling my attention like a magnet.

It had been a little over two weeks since my little sis had blown me in the car on our way home from school. I replayed that scene in my head over and over again, often feeling aroused when I did. She had told me later that she didn't mind what happened and, admittedly, she had found it to be pretty hot. Thinking about how she had gagged and coughed, practically puking my cum all over me from my cock being rammed so far into the back of her throat, was hot beyond words to me. Again, I knew it shouldn't be. She was still a teenager, for Christ's sake! It was like we were filming a porno in my fucking car. And I was such a glutton for it all that I wanted more.

I lay in bed one morning, quietly musing to myself and thinking about masturbating. My parents and wife were already gone to work. I was supposed to be getting ready for work myself, but I just wasn't ready to yet. When my bedroom door crept open, my heart sped up in my chest. I didn't even have a thought as to why Shelly wasn't already at school. My sister's face appeared in my doorway, and I couldn't help but smile at her as I felt my cock begin to grow. Christ, it didn't take much when it came to her.

But something was different. Something about her face. She didn't have the usual expression I had come to associate with her being seductive. She looked almost... serious. For a few seconds, she just stood in the doorway, staring at me. Then she walked in slowly and meandered over to my bed. Frowning slightly, I didn't say anything. She sat down on the bed beside me but didn't move a muscle after that. Yeah, something was definitely different.

Shelly lifted her head suddenly, turning toward me. Then she said simply, "I'm pregnant."

Sitting up quickly, my eyes opening wide, I said, "What? Oh fuck!"

My sister shrugged, looking away from me. Then she said softly, "No big deal."

"What??" I said, incredulous. "Are you joking? How the hell can it be no big deal?" I blurted out. It was a huge fucking deal.

She shrugged again, biting her lip. Staring down at her lap, she was fidgeting with her hands. I realized that her nonchalant attitude was just an act. Softening my voice, I asked, "And you're... sure?" I couldn't help but glance at her stomach. Was it bigger than I remembered?

She nodded at me without looking my way. One of her hands went instinctively to her belly, as if she were cradling it. Then she spoke to her lap, "Yeah, I'm sure. I haven't had a period in over two months. Plus, I feel..." She trailed off.

Leaning a little closer, I stared at her stomach. It didn't look any different to me, but then again, she was wearing a sweatshirt, so it could be hidden inside that. "You feel what?" I asked, softly.

Shelly shrugged again and then said, "I don't know. I feel like... like there's someone inside of me."

As I stared at my little sister, I realized something. I was feeling turned on. At the thought of my sister being pregnant. About her having a baby inside her belly. Why on Earth should that be turning me on, though? Squirming, I finally looked away from her, staring at the wall.

After a minute, Shelly asked quietly, "What do you think we should do?"

I turned my head toward her, frowning. "What do you mean?" I asked. As much as the prospect of her being pregnant turned me on, I couldn't help but think about what would happen when people started finding out. There was no way to hide being pregnant.

She looked at me, but then looked back down at her lap. She was fidgeting with her hands again, rubbing her thumbs against her palms. Then she shrugged and spoke in a quiet, voice, "I don't know... like, should I get an abortion?"

"Oh god, Shelly," I said. I hadn't even considered that. "I don't know. I... fuck, Shelly. This is bad," my words spilled out. It really was bad.

My sister sighed but nodded. Then she slid off the side of the bed and walked out of my room. I sat in stunned silence after she left, contemplating everything. Fuck. It was a mess. And what really seemed to be crazy was the fact that the whole concept had me simmering with arousal that wouldn't go away.

I had to go to work. And she had to go to school. She still had a couple months left before she graduated. So I forced myself to get up and get ready. Taking a shower, getting dressed, I went through all the motions as if in a trance. Shelly was already gone when I came out of my room, which made me sad for some reason. But I made myself go through the motions of working. Until I finally made my way back home later that day.

That night, we all sat in the living room watching a movie together. I couldn't focus on it at all. My sister sat across the room from me. Despite her eyes being glued to the tv, I could tell she was somewhere else entirely. And her eyes looked slightly puffy, as if she had been crying. Had she? Oh fuck me.

Wendy tried to have sex with me that night, but I wasn't in the mood. Well, I wasn't in the mood to have sex with her, that is. I was still feeling oddly aroused about my sister being pregnant. I made up some excuse that seemed to satisfy her and she finally rolled over and went to sleep. I couldn't myself. An hour later, I was still staring at the ceiling.

With a sigh, I made myself get quietly out of bed. Checking with a quick glance, I made sure my wife was asleep before slipping out of our room. Then I padded my way down the hall to my sister's room. When I knocked lightly on her door, she answered immediately.

"Come in," her soft voice drifted through the door.

Grabbing the doorknob, I twisted it and pushed the door inward. Once I was inside, I closed it quietly behind me. Then I walked over to her bed and sat down on the edge of it. When I looked at my sister, I knew she had been crying. A lot. Yet she didn't sniffle once as she looked up at me.

"Shelly," I said her name. She just stared at me, not uttering a word. We sat in silence for several minutes. Oddly, it wasn't really an uncomfortable silence. I liked being around her, even if we were quiet. But finally, I knew I had to speak. Taking in a deep breath, I repeated her name once more, "Shelly." Then I looked up at her and whispered, "I don't want you to have an abortion."

The smile that leapt onto my sister's face made me want to cry myself. It was the smile of sudden release from sadness. The unmistakable smile of joy. She had thought I was going to say something else and it made her sad. But to hear me tell her I didn't want her to get rid of the baby made her unbelievably happy. "Me neither," she said as tears started streaming down her face.

Emotion overwhelmed me in that moment. I realized I was crying myself as I leaned forward, moving toward her. When my face reached hers, I kissed her. On the lips. A real kiss for the first time between us. Tongue and all. And it felt like heaven. Her arms seemed to meld their way around my shoulders and onto my back and she sighed into my mouth, returning the kiss. Tears dampened our lips as we opened and closed our mouths. I gently prodded my tongue into her mouth, tasting hers. She tilted her head a little, gently pulling me closer to her. We fell onto the bed together and I slid my arms around her waist, holding her close.

For the next twenty minutes, I proceeded to kiss my sister with a level of sensuality I had never kissed someone before. Her lips were ungodly soft. Our kiss wasn't sloppy at all. It wasn't fervent like the way you might kiss someone when you were overcharged sexually. It was soft and slow and beautiful and passionate in a new kind of way. We weren't being sloppy about it. Just thorough. Our hands roved each other's bodies, petting and caressing our way up and down. We both avoided the sexual areas, without saying a word to each other. This kiss wasn't about sex. It was so far beyond sex, it was almost indescribable.

When we finally pulled apart, it was mutual. Shelly was smiling up at me from the bed and I was smiling down at her. Absently, I started rubbing her belly. Her pregnant belly. When I looked back at her face, she whispered, "Was that too intimate?"

Laughing, I glanced at her belly and answered, "I think we're kinda past that."

My sister giggled. Silence followed and I continued to explore her nineteen-year-old body as we lay in bed together. It was the still of the night and my wife and parents were elsewhere in the house. But I paid scant attention to that fact, or the fact that we could so easily get caught. I wanted to be right where I was.

Staring at my sister, I took in her beauty as if I had never seen it before. I stared at her gorgeous brown hair, following it down with my eyes. She had part of it draped over her chest. The way she was lying on the bed made her sweatshirt cling provocatively across her breasts. I realized I was breathing shallow breaths, my body warm and aroused. Slowly lifting my eyes to her face once more, she was staring at me.

"Shelly?" I whispered her name.

"Hmm?" she murmured, a lazy smile playing across her lips.

"I want to make love to you," I whispered. My words rang in my own ears and I knew how true they were. I didn't want to have sex. I wanted to make love to her. To connect with her. To be one with her. The urge was almost overwhelming.

Smiling, my sister said softly, "I told you. You can have me anytime you want."

Without hesitating, I reached my hands to the bottom of her sweatshirt and gently lifted it up her body. As her naked stomach and chest were slowly revealed, I felt my heart racing. For a few seconds, I stared at her belly to see if I could tell she was pregnant. There seemed to be a subtle bump in the center of her stomach, but that was all. It was proof enough, though. And seeing it made my cock begin to throb.

Shelly helped me take my shirt off, and then we each took our own pants off. Less than a minute later, I was lying naked in my sister's bed, snuggling up beside her. She lay on her back, breathing softly. Leaning forward, I lowered my lips down to her chest and, for the second time in my life, I wrapped my lips gently around my sister's perfect nipple.

She moaned quietly at my oral attention. Using my lips, I clamped them down into her skin, gently sucking her nipple up into my mouth a little. Batting at the tip with my tongue, I slid more of my weight onto her. My hand was on her belly, rubbing tiny circles around her navel. Her hand grasped my shoulder and then she was sliding her fingers down my arm, creating a wake of tingles along my skin.

Shifting my mouth from one breast to the other, I took her other nipple between my lips next. More than half my body was lying on top of hers by then and our hands were freely roaming each other. No words were necessary as we became quietly erotic. Our short breaths echoed off the walls of her room. The sounds of our hands caressing each other's bodies mingled with the sounds of my suckling mouth as I continued to tease each of her nipples.

I don't know how long we petted each other, but by the time I climbed the rest of the way onto her body, my penis was fully erect and tingling for release. Shelly spread her legs without prompting and I nestled my hips in between them. Lifting my head from her breast, I looked up and found her staring down at me. That enduring smile was still etched across her lips.

Sliding my way up her body, our lips connected just as I felt my penis poke its way inside her pussy. Without a sound, our kissing became more passionate. My cock slid deeper into her. Her hands made their way onto my back, rubbing me. She was perfectly wet down there. Not so much that there was no friction at all, but not so little that there was any sort of resistance. I could feel her vaginal walls hugging my cock, almost lovingly. I had never experienced anything like it in my life. The tingles it produced up and down my shaft as I slowly rocked myself into my sister's pussy were insanely strong. It was like a thousand tiny little pleasure points all up and down my penis.

Our tongues made love in our mouths while our bodies made love in my sister's bed. Gently I rocked myself in and out of her. I never sped up. It wasn't about speed. It wasn't that kind of passion. My cock slid all the way inside her, over and over again. Her body was trembling, but it wasn't the tremble caused by being on the brink of orgasm. It was a tremble of passion. I realized I was trembling, too.

For over an hour, my sister and I made love to each other. Our hands explored each other's bodies, reaching every possible place we could reach. I remained on top the entire time, but never once did I feel like I was in total control. We shared control completely. Her pussy never stopped producing enough juice to keep her nicely lubricated. In and out I slid, penetrating my sister over and over and over again. It was, without a doubt, the most sensual experience of my life. No question.

Finally, I knew it was time to cum. For both of us. Again, we spoke not one word. My gentle thrusts grew subtly more intent. I felt her hands squeeze my lower back. In and out I rocked, letting the pleasure soar. It rose, getting stronger and stronger. My tongue invaded Shelly's mouth, but it was welcome. We were both breathing through our noses. I felt her trembling turn to shaking and then her hands slid down to my butt, and she squeezed harder.

Forward and back I penetrated her. Her hips rose up off the bed. I slid one hand between us and gently squished one of her nipples with my thumb and forefinger. I felt her pussy squeeze my cock in response. Then it was happening. We came in perfect unison. Her clenching pussy muscles milked the cum right out of my cock. I felt my sperm gently squirting inside of her. Her body trembled, as did mine. Still rocking in and out of her, I continued to fill her with my cum. Our bodies swam with pleasure from head to toe. We vibrated together in each other's arms while we came. It was an experience like none other for me, and I knew she felt the same. We moaned as we continued to kiss, but they were quiet sounds that resonated gently over our tingling bodies.

Our orgasms lasted well over ten minutes. I wasn't cumming the entire time, but the sensation was there. The tingling pleasure that threatened to make me insane if it went on much longer. Our lips remained locked through the entire thing. And when the crescendo was finally surpassed, it felt like we were drifting back down to earth together. Our bodies sank into the bed and my rocking gradually slowed.

When we stopped moving, I pried my lips from hers and lifted my head. Staring down into her eyes, I smiled. She was smiling up at me. Then she whispered, "We're going to have a baby."

"Yes," I whispered back.

Closing our eyes, my sister and I drifted off to sleep, bodies locked together from our lovemaking. My cock never left her vagina at all that night.

PART II.

Shelly started showing her pregnancy over the next month. It was subtle at first, but since I was looking for it, I saw it plain as day. My wife was the first one in the house aside from me to notice it, too. She said something to me about it in the privacy of our bedroom one night. It was just an offhanded comment she threw out while she had her eyes closed, trying to fall asleep.

"Your sister looks like she's pregnant. Either that, or she's been eating a lot of cookies lately," she said.

I didn't know how to respond, so I just said something noncommittal. It seemed to satisfy her as an answer because she was snoring just a few minutes later.

Then one night, two weeks before my sister graduated, everything came to a loud and violent head. My wife and I had just gone to bed a few minutes earlier. I had barely turned out the light when the screaming started. It was my mom and my sister, shouting at each other. Mostly my mom. I couldn't quite make out what they were screaming, but I had an idea what it must be about. My wife and I looked at each other and she mouthed the words, "Told you."

With a sigh, I closed my eyes. I desperately wanted to go intervene, but I was worried that it might somehow link me to my sister's pregnancy, as absurd as that was. How could I be linked? Nobody would suspect that in a million years. Would they? I hoped to god my sister could keep her cool and not give anything away herself.

Something crashed somewhere in the house, and I sat up in alarm. Why wasn't my dad helping to chill things out? He always did. When another crash made the wall behind my bed shake, I growled and threw the covers aside as I got out of bed.

"You're going to get in the middle of that?" my wife asked, sounding like it was the stupidest idea in the entire world.

Shrugging, I grabbed a t-shirt and tugged it on over my head. Then I went to investigate without a word. My mom's voice echoed from the far end of the house as she started screaming again. As I got closer to my sister's bedroom, I could hear her crying. Hard. Then my mom shouted, "Tell me who did this to you!"

Quickening my step, I reached the door and turned the knob. As the door swung open, two heads swiveled to stare at me. Their expressions were both near hysterical, if for different reasons. My sister's eyes were red and puffy, and her cheeks soaking as tears actively trickled down them. When she saw me, she gave the slightest shake of her head. I knew exactly what it meant. She wasn't going to tell.

Shelly turned back to my mom and said, "It's none of your business, mom."

My mom's face, which had already been red, seemed to start glowing as her anger increased. Opening her mouth, she shouted, "It is absolutely one hundred percent my fucking business, young lady! You are still in high school! How could this happen?"

When my sister didn't answer, my mom took a step toward her, raising her hand in the air. That was my cue. Two rapid steps took me right behind my mother. Reaching out, I deftly grabbed her hand just as she started to swing it toward my sister's face. She turned to look at me with a startled expression on her face. Her eyes narrowed and she opened her mouth to yell at me, but I spoke first.

"Mom, you should talk to her about this later. After you cool down," I said, trying to convey a calm that I didn't feel at all.
