“Hey, there, sis,” Mick said, wrapped his powerful arms around me and planted a kiss on the top of my head. “How are you?”

“Fine,” I said. A familiar thrill traveled up my spine as my brother-in-law pulled me close.

The spark I felt when Mick held me was undeniable. Maybe it had something to do with his being married to my older sister, Cindy. She always seemed to have more than I did — she got boobs first, she lost her virginity before me, and was the first one to get married.

And then there was Mick.

He was tall and muscular, like a statue sculpted from stone, with tattoos that told stories on his skin. Before I married Harvey, I often wondered what those marks tasted like. Hey, I was young when Cindy and Mick got together, so you’ll have to excuse my teenage fantasies.

“Sarah! Hi!”

Cindy moved through the door, her large, pregnant belly bumping into us. “Mick? Quit messing with Sarah and help me!”

Mick pulled back, somewhat reluctantly I noticed, and I caught a knowing smile on his lips.

Damn! That bastard knew what he was doing to me!

Mick had continued to haunt my dreams throughout high school. Then, my senior year, my sister’s husband finally noticed me. My breasts had filled out and my waist narrowed, giving me an hourglass shape my sister could only dream of. Mick began giving me lingering looks when I stayed over and flirted with me when Cindy wasn’t around. Nothing ever happened, but that didn’t stop me from imagining Mick when I touched myself.

Then, I met Harvey. Harvey was everything Mick wasn’t. He was a nerd, with thick glasses and a thin frame, which he insisted on making thinner by wearing baggy shorts and long button-down shorts. Still, he was sweet and smart and I adored him in a way I had never felt for anyone else. It may not have been lust at first sight, but that didn’t matter. I loved Harvey and, fora while, that was enough.

Then Cindy began to have babies. First one, then another. Now, here she was again, six months pregnant and looking just as glowing and wonderful as she always did when she was carrying.

As I watched Cindy sigh and cradle her growing belly, I couldn’t help but feel a pang of jealousy. Harvey and I had been trying to conceive for over a year now, and despite all our efforts, nothing seemed to work. Every time I saw Cindy with her children, my heart ached for the child I so desperately wanted.

As if on command, Ashley and Thomas, 5 and 7 years old, came bursting through the door, filled with the boundless energy of the young.

“Auntie Sarah!” Ashley cried and threw herself against my legs. “I missed you!”

I chuckled and dropped to my knees, embracing Ashley with a big hug. I then gestured for Thomas, who rolled his eyes in a perfect parody of a teenager before eagerly joining us.

Finally, I let them go and Ashley looked serious for a moment, then placed a hand on my belly.

“Do you have my cousin growing in your belly?”

“Ashley!” Cindy cried and tried to pull my niece away, but I stopped her.

“It’s OK,” I said, blinking back a tear and feigning a smile. “Not yet, sweetie!”

“Aww,” Ashley pouted, then suddenly brightened. “That’s OK! I’ll be your little girl ’til then, OK?”

“Always!” I laughed and hugged her tight, my heart breaking a little. I couldn’t stop the tears from dripping down my cheeks, but I didn’t want Ashley to see.

Luckily, a moment later, I heard Harvey’s voice enter the hallway.

“What’s all this?” Harvey said in mock outrage. “Who are these hooligans attacking my wife?”

“We are not hoo-lee-guns!” Thomas barked indignantly.

Ashley broke our hug and looked up at my husband, her face beaming.

“Uncle Harvey!” she let out a scream that made my ears ring, then ran to Harvey, who scooped her up in his arms and gave her a hug.

“Oh, my gravy!” Harvey said. “You’re getting so big.”

“Uh huh!” Ashley agreed. “I am!”

“What about me?” Thomas asked.

“Thomas? I didn’t even recognize you. You’re so tall!”

“Aww, you’re kidding. Uncle Harvey.”

“Never!” Harvey chuckled and gave me a wink over Thomas’s shoulder. He saw my tears, yet he wisely refrained from commenting.

“Kids, why don’t we see where Aunt Sarah hid all the candy?”

“Candy!” the kids cried as Harvey carried Ashley into the house, Thomas following behind.

“Not too much, Harvey!” I called. “You’ll spoil their dinner!”

I stood up and wiped the tears from my cheeks. Cindy came up to me with a sympathetic smile on her face and gave me an awkward hug. Her round belly pressed against me, nearly making me cry again.

“I’m sorry, honey.”

“It’s OK,” I said, even though I felt anything but OK.

“I’m sure it will happen soon.” Sarah said, the trite saying women with children always said to women who couldn’t conceive.

“Yeah,” I said dutifully.

At that moment, my gaze locked with Mick’s as he stood framed in the kitchen doorway. His eyes burned with an intensity that shook me to my core. The thrill of his embrace echoed through me, sending a wave of fire surging throughout my body.

There was an intense hunger in that stare, and it made me weak.

“Are you OK?” Cindy said and held me at arm’s length. “You’re shaking.”

“No, I’m fine,” I said. “Just happy you’re here.”

Sarah smiled, and I glanced over my sister’s shoulder, but Mick was gone.

I had a hard time concentrating at dinner. Thoughts of Mick distracted me and my mind kept returning to the brief moment we shared, and I found myself glancing at him across the dinner table.

It was only a matter of time before Mick caught me looking and gave me that damned knowing smile. I looked away quickly, my cheeks burning.

“You OK, sis?” Cindy said.

“Yeah, I’m fine,” I lied.

“Are you sure it’s OK if we stay the night?” Cindy asked.

“Of course!” I said. “There’s no reason for you to drive all the way back home. I’m fine.”

Cindy opened her mouth to say something else, but Mick stopped her.

“She said she’s fine, Sarah,” Mick said. “Stop trying to big sister her.”

“Well.” Cindy pouted. “I am her big sister.”

“Yes, but Sarah’s a big girl now. “ Mick gave me a look that made my pussy twinge with lust. “She can make up her own mind.”

I shifted uncomfortably and wiped my suddenly sweaty hands on my jeans. I looked at my sister and her husband, trying to ignore my body’s reaction to Mick’s words.

“It’s settled then,” I said with a bright smile. “You two can stay.”

“Fine, fine,” Cindy grumbled and finished her drink. “If you insist.”

“I do.”

After dinner, Cindy and Harvey took the kids into the den to watch television, while Mick and I took care of the dishes. As we worked in silence, I glanced over at him, watching him as he rinsed off a dish and handed it to me.

“I can do that, Mick.”

“I know you can,” he said and continued rinsing dishes. “You’re a strong, independent woman.”

“What’s going on, Mick?”

“Nothing,” he said with a smirk. “Just thought I would help you out.”

“Are you sure that’s all?”

“What do you think?” he said, his eyes boring into mine.

“I… I don’t know.”

He stepped close to me and cupped my cheek. I felt my skin heat under his touch and I couldn’t help but lean into it. His touch was a flame and like a moth I was drawn to that fire.

“I think you know exactly what’s going on, Sarah.” Mick’s lips twitched, and he leaned close to me. “Is this what you want?”

I bit my lower lip and nodded.

“Say it, Sarah.”

“Yes,” I whispered, all of my girlish fantasies rising up and overwhelming the guilty thoughts. After all, it was just a kiss, right?

Mick flashed that smile, they one that said ‘I knew you wanted me’, and placed a hand on my shoulder, then pushed me back gently, guiding me until I was against the counter. My body went numb as his lips met mine, soft and warm. A fire ignited in my core as our lips touched, and I reached up and pulled him closer to me, deepening the kiss.

“Fuck,” Mick whispered. “You poor girl.”

“What do you mean?” I said breathlessly.

“Stuck with that wimp, Harvey? I’ll bet he doesn’t know how to treat you.”

“Please, don’t,” I moaned and looked towards the door where my sister and Harvey were watching T.V. oblivious to the drama being played out in the kitchen. “Harvey’s a good man.”

“Oh, I’m sure he is,” Mick scoffed. “Just not man enough to knock you up.”

“No,” I breathed. “That has nothing to do with it!”

“Oh, no?” he asked, his cruel smirk sliced through my defenses. Of course, Sarah had told him about our problems having a child and I am sure she told Mick about Harvey’s low sperm count. It wasn’t my husband’s fault, but sometimes it sure felt like it.

“Ah, see?” Mick said, his finger hooking my chin and tilting my head up. “You know I’m right.”

“No — “ I tried to protest, but Mick kissed me again and I moaned into his mouth. His hand moved down to my hips, then across my stomach and around my breast. I gasped as he massaged my tit, gently squeezing my nipple between his fingers.

“God, Mick!” I cried, breaking our kiss. “We can’t!”

Mick looked towards the door, probably picturing his wife and children in front of the T.V., my husband beside them. Harvey would be sitting next to the kids, making them laugh. He would be such a good father.

It was just too bad he couldn’t give me a baby.

“Shh,” Mick whispered. “Just let me help you.”

His hand slid down the front of my pants, under the waist band, and dug between my legs. Of all the times I’d imagined being with Mick, I never imagined he would be feeling me up while our family waited just outside the door.

“Oh, fuck,” I cried.

“That’s it,” Mick whispered, his fingers finding my clit and rubbing it gently. “Just relax, Sarah.”

“No,” I moaned. “Mick… please.”

“Just let me take care of you, sis.”

His fingers moved faster, sending a wave of pleasure washing over me, making my legs weak. I closed my eyes and tried to stop him, but he continued to kiss me, and I couldn’t do anything but submit to his touch.

I came on his fingers and moaned into his mouth. He kept rubbing until my orgasm subsided, leaving me panting.

Mick pulled his hand from my pants and lifted his fingers to his mouth, sucking them clean.

“Honey?” I heard Harvey outside the door. I grabbed my jeans, pulling them in place and securing the top button just before Harvey opened the door.

“Hey, honey!”

I glanced over at Mick. He had moved quickly and silently back to the dishes as if nothing had happened. I smiled at Harvey, hoping he didn’t notice my flushed cheeks or the prickles of sweat on my forehead.

“What… what do you need?” I asked, stammering a bit.

“Just some sodas,” he said, then raised his hands. “Don’t worry, I’ll get juice for the kids. Can you make some popcorn?”

“Sure,” I said as Harvey opened the fridge and grabbed some drinks. He stood up, then stopped, looking at me curiously.

“Are you OK?” he asked. “You look flushed.”

He raised a hand and felt my forehead before I could stop him. His hand came away damp.

“Sweaty, too,” Harvey said. “Are you getting sick?”

“No,” I said. “I’m fine. Just a little hot in here.”

“Don’t let her fool you, Harvey, “ Mick said from the sink. “She hasn’t been feeling well since dinner.”

“What? Really?”

Mick smirked at me over my husband’s shoulder, that now familiar hungry look in his eye. I suddenly realized what he was doing. He was giving me an opportunity. It was up to me whether I wanted to take this to the next step.

“I’m sorry, baby,” I said. “It’s true. I don’t feel well.”

“Oh! Why don’t you go lie down and I’ll bring you a cool drink? Would that help?”

Mick was nodding now, his smile cruel and beautiful. Oh, God! Was I really doing this?

“That would be great,” I smiled at my husband, feigning weariness even though adrenaline was pounding in my veins. “Thank you.”

“I love you, Sarah,” Harvey said and kissed me softly. I was hyperaware of Mick watching us the whole time and my pussy, already dripping from my orgasm, flooded my panties and my juices dripped down my thighs.

“I love you, too, baby,” I murmured and headed to the bedroom. I looked back and saw Mick speaking to Harvey, wondering what he was saying, then I walked to the bedroom, opened the door, and shut myself inside.

I sat on the bed. I tried to forget what had happened in the kitchen, but I could not deny how thrilling it was to feel Mick’s masterful hands on my body.

My heart raced as I heard footsteps in the hallway outside my bedroom door. Was it Harvey or Mick? My breath caught as the door opened and Mick stepped inside, carrying a glass of water. His eyes gleaming with desire in the dim light.

“I convinced Harvey to let me bring you a drink,” he grinned and placed the water on the side table.

He turned around and slid off his shirt, revealing his muscles chest, the tattoos snaking over his skin. My mouth was suddenly dry at the thought of tasting those marks, running my tongue over the snaking trails.

Mick saw my need, leaned down, and kissed me deeply, pressing his body against mine and making me gasp at the sensation of his hard muscles on my soft curves. My hands traveled over his finely muscles shoulders, so much harder than Harvey’s soft body. Mick pulled back and before he could pull away, I planted my lips on his skin, licking along a dragon’s tail. He tasted of salt, sweat, and sex, the sensations leaving me weak.

Mick pulled away slightly, just enough so that we were both still breathing heavily. His eyes searched mine for one long moment before he spoke quietly:

“Do you want this?” he asked softly.

I hesitated. If I did this there was no going back. I would forever know that I had cheated on my husband. Plus, I could get pregnant, a reminder for the rest of my life of this betrayal.

And yet, my lust for my sister’s husband was crashing against the primal urge to get pregnant. Here, in front of me, was the biggest strongest animal in the forest and the fertile beast inside of me wanted him.

I nodded without saying a word, unable to look at Mick. Mick lifted my chin and gazed into my eyes, letting me know that this was not my husband waiting above me. This was my sister’s husband and he was going to fuck me.

He kissed me hard, his tongue stabbing into my mouth. My silent submission broke any restraints holding him back. He tugged at my shirt and I raised my arms above my head so he could pull it up over my head. I reached behind me and unclasped my bra, baring my breasts to a man that was not my husband.

Mick growled and dropped to his knees in front of me, his mouth moving to my left breast, his tongue swirling around my nipple, then flicking it. I moaned and arched my back, pushing my tits into his face.

Mick’s tongue found my other nipple and sucked it hard, his fingers stroking my swollen areolas. I whimpered, my legs trembling as he teased me with his tongue, slowly pushing me down on my marital bed.

I whimpered as I caught a glance of the picture on the bedside table. Harvey and I were smiling, he in his tux and me in my wedding dress. It had been a beautiful day, our whole life full of possibilities.

The happy couple looked on as Mick skinned off my jeans and panties, laying my body bare. While my sister and husband were watching T.V. just down the hall, I was about to give everything, my body and my future, to my sister’s husband.

Mick smiled down at me, a mixture of lust and smugness in that grin. He knew he had me and he pushed his pants down over his hips. His cock, huge and fleshy, burst from his pants. It was so much bigger than Harvey’s, so much more manly. If anyone could get me pregnant, it was Mick, and he knew it.

“You want this cock, sis?” he asked, the nickname making lewd shivers of lust run through my cunt.

“Yes!”

“What about your husband? You want him to raise my baby?”

“Please, Mick!” I moaned. “Please, don’t be cruel! Just give it to me.”

“I will,” Mick said, moving forward and swabbing the tip of his cock over my needy pussy. “Just tell me you want my baby. Tell me you want me to fill your belly up like your husband can’t.”

“Oh, God!” I moaned. I should have known it wouldn’t be that easy, that Mick was too cruel to let this moment pass him by.

But I needed him. I had needed him for years. And now, here he was, ready to give me everything I ever wanted.

“Tell me, sis,” he demanded. “Tell me you want my baby!”

“I want your baby,” I whispered. “I want you to give me a baby.”

Mick laughed, then pulled back and slammed his cock deep inside me. I gasped in pain and pleasure, my pussy stretching to accommodate his girth. God! He was so much bigger than Harvey!

Mick started thrusting into me, slowly at first, then faster. My breasts bounced as he pumped his hips, driving his dick into my womb.

“God, Sarah! Your cunt’s so tight!” he grunted. “I can’t wait until you get knocked up. Your pussy’s gonna milk this cock dry!”

“Oh, fuck, Mick,” I cried, arching my back to take more of his cock into my hungry pussy. “Fill me up, please! Make me pregnant with your baby!”

“You want me to breed you?” he said, his hips bucking faster.

“Yes! I want you to knock me up! Please! Just fill me up!”

“What about your husband, Sarah?” he said. “What about Harvey?”

I moaned with anguish, but his words did nothing to quell the heat inside my pussy. If anything, the thought of Mick’s baby growing inside me made me even more excited.

“I don’t care!” I cried. “I don’t care! I just want your cock!”

Mick was pounding into me now, harder than he ever had. His fingers dug into my thighs, leaving bruises. The bed was groaning under the punishment and I had a crazy thought we might break it, the same way Mick was breaking me.

“Say it again, Sarah. Tell me you want my baby.”

“I want you to knock me up,” I sobbed. “Oh, God! I want to be pregnant by you!”

“You will be, sis,” Mick said, slamming his cock into my cunt. “You’ll be knocked up soon, full of my baby.”

“Oh, fuck, yes!”

I was so close now, teetering on the edge of climax, and he pulled his cock out again, making me cry out in frustration. He pushed my thighs up until I was bent in half, my thighs mashing me breasts against my rib cage. I moaned, my body trembling for his cock.

He didn’t disappoint.

Mick slammed inside me, stretching my pussy wide and making me cry out. I could only hope the T.V. volume was high enough to drown out my desperate cries.

Then, Mick forced all thoughts from my miind as he pounded me into my marital bed. His heavy balls smacked against my ass, punctuating each soul shattering thrust.

“I’m going to come inside you,” he growled thrusting into me hard. “I’m going to fill you up with my baby.”

“Oh, God, Yes,” I sobbed. “Please, please, please, do it! Please come inside me!”

“Come with me, sis! Come with me!”

He hammered inside of me, his eyes boring into my soul. I could tell he wanted to come, but he was waiting for me, holding back his lust so he could share this final act of betrayal with me. The emotions all crashed inside my body, building with the physical pressure, and me body tensed then exploded as my body gave into my brother-in-law’s vicious pounding. My pussy contracted around his life-giving cock and a Mick joined me, forever connected to me by this moment, a moment I would never forget no matter how much I loved my husband.

“Oh, God, Sarah!” Mick groaned, then pushed deep inside me. I cried out as he filled my womb with his cum, hot jets of jism shooting into my unprotected body.

So much cum! The drunken thoughts beat at my brain. I’m getting pregnant!

Finally, I collapsed back onto the bed, gasping for breath, my body shaking from the aftershocks. Mick pulled out of me and he moved up beside me on his knees, his dripping cock inches from my face.

“That was amazing,” I said and smiled gratefully.

Mick returned my smile and slid his cock over my lips. I knew what he wanted, and I opened my mouth, licking the salty cum and my tangy juices from his shaft. He moaned in pleasure, pushing his cock between my lips and I sucked the last of our lust from his beautiful flesh.

Finally, he pulled back, smiling warmly down at me, brushing my cheek with his hand.

“We may have to do this again,” he said. “Just to make sure you get pregnant.”

I nodded, knowing there was more to it than getting me pregnant. Mick wanted me again. I felt a warm sense of pride, despite the shame I felt for cheating on Harvey.

“You rest,” Mick said. “I’ll let them know you’re OK.

“Thank you,” I murmured and watched my sister’s husband and, possibly, my baby’s father, leave the room.

“Do you feel better?”

Harvey came to bed an hour later. His look of concern made a shaft of guilt spear into my heart.

“Yes,” I said and gave him a tight smile. “I think I’m OK now. It must have been something I ate.”

“Are you sure?” Harvey asked, running a hand along my forehead.

“I’m sure,” I said and gave him a reassuring smile. “I’m sorry I made such a fuss.”

“It’s OK,” he said and leaned over to give me a kiss. I felt his tongue lick my lips, and I opened my mouth. My pussy throbbed as Harvey licked the last of Mick’s cum from my lips.

He sat back, a confused look on his face.

“You all right?”

“You taste different,” he said, and my heart froze. Then Harvey licked his lips and smiled. “Good, but different.”

I suppressed a sigh as Harvey laid down next to me, his arms encircling me, his hands settled on my belly.

The same belly where Mick’s baby might even now be growing.
