My Other Half

On their 18th birthday, twin siblings consummate their deep bond in a passionate, forbidden encounter that changes everything.

Chapter 1

My sister Melanie and I had always been close. We had been since the day we were born. Which, as it happened, fell not just on the same day but at the exact same time. We were fraternal twins.

I was technically born first, but only by a couple of seconds. My name is Daniel. As twins we are almost identical in appearance, except for the fact that I was a boy and she was a girl, of course. But even for fraternal twins we were more identical than most. We both had the same sleepy blue eyes that we inherited from our dad, and we both had the same light brown hair. Melanie's parted in the middle and fell down the sides of her face, curling at the bottom. My own was parted to the side and feathered back. We both had the same round cheeks, the same splattering of freckles across the bridge of our nose. Our faces were practically the same, with simply a different hairstyle to denote our genders.

And, as twins, we shared that same magical bond that other twins claimed to have experienced. It was true that we often finished each other's sentences. We had a way of knowing what the other was thinking simply by looking at each other, and Mom used to say it was like we could speak to each other telepathically. I could always tell what sort of mood she was in, and while that sounds like simple intuition, it doesn't explain how her mood and my mood somehow always seemed to sync up.

When Melanie and I were younger, we always had a way of sticking together. We were so close, in fact, that Mom would often scold us and tell us that what we did wasn't proper for a brother and sister. We never understood what was strange about it ourselves.

I mean, we would kiss sometimes, sure. But I thought all family members did that. We may have done it a little more often than most, but we figured we were closer than most siblings. We were twins.

This year my sister and I were turning eighteen. Our birthday fell in the Spring, and the weather had just started to turn warm. Because of this I had kicked the blankets off myself in my sleep, lying only in an old pair of cotton pajama pants that had Garfield on them. I wasn't wearing a shirt.

There was a warm, pleasant sensation that seemed to invade my dreams, and it began to overwhelm everything else. My dream began to crumble away as I focused solely on the sensation, and because of this I unconsciously began to wake up. The dream melted away completely as I realized that my cock was very hard, and it was gently because caressed by something warm and wet.

I looked down, and there was Melanie, her cute little lips slowly sliding up and down my member. She looked back up at me innocently, fluttering her pretty eyelids. Gradually, she pulled me out of her mouth with a wet pop.

"Happy birthday, big brother," she said sweetly, and smiled. It was a joke that we sometimes called each other 'big brother' and 'little sis,' since we were only seconds apart.

I smiled back at her, relishing the sensation. "Happy birthday, little sis," I said. "You're giving me my present early this year."

Melanie giggled sweetly. "It seemed like a special occasion. After all, this is the year we become grown-ups. I thought we should start it by acting like grown-ups."

I laughed. "And this is what grown-ups do all day?"

Her smile was radiant. "Well, the happy ones, at least. Besides, it's one of the things they do. Would you rather start your birthday doing taxes or something?"

"No, no...you're right. You win. Go ahead and suck my cock." I chuckled and looked down at her. She had extended her tongue and was swirling it around the head of my penis.

"I'll suck your cock when I feel like it, jerk," she said playfully, then suddenly she slapped my thigh. She then took my shaft and began slapping herself in the face with it, opening her mouth and letting it hit her tongue.

I reached down and grabbed the base of my cock from her, pulling it out of her hands. I then proceeded to slap her myself, letting my meat smack against her tongue with a wet sound. She moaned gently as I did so, and then all of a sudden she pounced on it, wrapping her lips around it tightly and bobbing her head quickly.

"Oooh!" I exclaimed. The sensation of my sister sucking my cock was certainly familiar to me but she did it so quickly and eagerly this time. "That's it, baby sis...suck that dick. It's you and me, always..." I whispered, my breathing growing heavier.

"Mmmmm," Melanie moaned around my shaft, and then suddenly she stopped. Withdrawing her lips from the head of my penis, she looked up at me sweetly.

"Forever and ever, big brother." She smiled. "Nobody can ever separate us." She kissed my shaft gently, right on the underside where it was most sensitive. And then she was at it again, her sweet, unblemished face wrapped around my manhood, sucking it with renewed vigor.

I watched her work, and marveled at how much just like me she looked. She was beautiful, yes, but at the same time it was like she was a part of me. This couldn't really be wrong, because we were one and the same person.

Suddenly we heard footsteps in the hallways outside our bedroom. It was true that we shared a bedroom still, even at our age. Our parents weren't happy about it, but they tolerated it because our beds were on opposite sides of the room, there was a screen between us, and because we were twins my parents used to think that we were less likely to be intimate.

This morning our parents apparently decided that it would be fun to surprise us, seeing as it was our eighteenth birthday. They burst into the room carrying flowers and balloons, singing "Happy birthday" to both of us together. Mom went towards Melanie's bed and Dad come over to mine.

Melanie quickly pulled my cock out of her mouth and ducked underneath the blankets, pulling them up to cover us both. I shoved them back down again, uncovering my own face, at least. She stayed hidden under the blankets and tried to gently pull the front of my pajama pants back up as Dad approached the bed.

"...Happy birthday, dear Daniel and Melanieee....!" he sang idiotically, purposefully singing badly the way fathers will do.

He stopped when our mom suddenly exclaimed, "Oh! She's not here..."

"What? What do you mean?" Dad asked our mother, turning to her suddenly in mid song. "Where is she?"

"I don't know, but she isn't in her bed. Daniel, where's your sister?" She turns and looks at me.

The blankets beneath begin to shake and pulsate, and suddenly Melanie's head emerges. She is lying next to me and looking sheepish, her normally neat hair caught in her face. "Hi, Mom." She tries to look at her father. "Hi, Dad."

"What the...?" Dad asks incredulously. "Melanie, why are you in bed with your brother?"

Mom scowls at us, but says nothing. She has caught us in these situations too many times before.

"Oh, Dad." Melanie says, putting emphasis on his name. She sounds sarcastic, like their father is just being dramatic. "It's our birthday. I was just giving my bro a hug." She puts an arm around Daniel's bare chest and squeezes.

"Yeah, I bet." Mom says sourly. "Get off your brother, Melanie, and get dressed. We had birthday surprises for you guys, but I guess you're already celebrating early."

"Mom, don't be stupid. I was just giving my twin brother a birthday hug." She climbs out of bed as she speaks. Despite her words, everyone can see the tight tank top and panties she is wearing, and the fact that Daniel is shirtless. Even if there was nothing going on they were far too comfortable for a brother and sister.

"Uh huh," Mom says, glaring at the way she is dressed. "So much for your birthday wake-up call. I guess Melanie already did that." She turns and trudges quickly out of the room.

"Get dressed you two, and get downstairs. And happy birthday." Dad says grumpily, his patience worn thin now. He's not even sure what's going on, but he knows Mom is unhappy and so he is too. With a final scowl at me as if to say 'you should know better' he turns and walks out behind her.

As soon as they leave my sister and I start to crack up. We should be seriously freaked out by this, but somehow that makes it even funnier.

"Holy shit that was close," Melanie giggles. "I think Mom may have seen me with your dick in my mouth."

"No...she didn't know where you were at first."

"So she says," Melanie says, and shrugs. "It doesn't matter, nothing's going to come between me and my bro. Not on our birthday, especially. Now, hurry up, they're waiting for us."

To my surprise, my sister suddenly yanks the front of my pants down again and shoves my still semi-hard erection back into her mouth. She begins to bob her head quickly up and down, swirling her tongue around the head.

The sensation is incredible, and made all the more erotic by the fact that we nearly got caught by our parents. I do my best to hold on, but she is so pretty and her lips are so soft.

"Oh, sis...oh my God..." I breathe, and there is no stopping it. She makes me cum quickly, and my seed overflows into her mouth. She lets it collect there, not swallowing yet, as I release jet after jet of hot, salty semen into my sister's eager mouth.

Melanie pulls her mouth away as the shudders subside, and she looks at me with an innocent smile. As I smile back at her, she suddenly opens her mouth and shows me my load, resting on her tongue. Still grinning mischievously, she throws back her head and lets the hot fluid run down her throat. She then opens her mouth again, showing me that it is gone.

I laugh softly, and shake my head. "You're such a good sister. I love you so much."

"I love you too, bro. Now come on," She stands up, still wiping her chin. "Lets get downstairs before Mom and Dad call the police on us."

Chapter 2

Melanie and I spend the day with our parents, and unfortunately with most of the extended family as well. Our grandparents come over, who are in their eighties, as well as our extremely annoying alcoholic Uncle Ralph. Beyond that the only person there I like is my younger cousin Jimmy, but he's still a kid.

"This is boring as hell," I mutter to Melanie, as the adults gather around the living room. We were seated next to each other on the steps leading upstairs, letting the adults have the good seats. They begin talking about matters that only the very old would care about, and even Uncle Ralph looks bored as he swigs a beer.

She nods. "Yeah. I can't wait until later," she whispers back to me.

"What happens later?" I ask, but there's a grin on my face. Like I needed to ask.

Melanie turns to me and winks. She is wearing a tank top today that befit's the warmer weather, and from the side I'm able to get a pretty decent view of her side boob. Her breasts are not overly large but they aren't tiny either, fitting a respectable B cup, and in my opinion they're perfect.

"Am I going to get another birthday present tonight?" I ask her quietly, and Melanie giggles.

"Well...you know it is MY birthday, too," she says, the lilt in her voice teasing. She nudged me gently with her hip.

Mom suddenly looked over at us. There is a scowl on her face, as there often was when she looked at me and my sister together. Both of us suddenly get quiet, although Melanie can't seem to erase the mischievous grin off her face.

"We need to be cool," I finally muttered after Mom looked back at something that Grandma said. "She's getting suspicious. I don't think she likes that we do stuff together."

Melanie smirks sarcastically. "No, of course not. The bitch hates to see us happy."

"She thinks it's not appropriate for us to kiss, even. I mean, we're brother and sister. We're twins. Of course, we're going to be close. You can't tell me that other brothers and sisters don't ever do that." I shook my head and looked at my feet.

She shrugged. "I don't know, honestly. The few girls I've talked with in school don't ever mention it. And Carla doesn't have a brother," she says, referring to her only friend in school. Melanie and I mostly stuck to each other.

"Well, if you look it up online, it seems like it's pretty normal. There's a lot of stuff with brothers and sisters there."

Melanie laughs. "Yeah, I bet there is. I don't know if that counts as proof, though."

I shrugged. I had seen the videos, read the articles. Didn't seem that unusual to me.

The rest of the evening, Melanie and I stuck close together and weathered the storm that was our obnoxious family. We accepted the gifts they got us with grace, pretending to be excited about the matching blue sweaters that Grandma had knitted for us. Only Uncle Ralph gave us anything useful, simply sliding a $100 bill in a joint birthday card for us to split.

As the hours wore on and the "festivities" came to a close, everyone began to come up with excuses to leave and we were slowly given our house back. Mom and Dad picked up the dishes, telling us we were exempt due to it being our birthday. We instead adjourned to the living room couch, and Melanie started to flip through the channels.

"Do you two have to sit so close together?" Mom asked us as she passed back and forth in the kitchen. "There's plenty of couch, why not spread out?" She was trying to keep her tone casual, and not succeeding very well.

I looked at Melanie and realized that while she was on the end of the couch I had chosen the middle cushion, and actually was pressed up pretty close to her. She had draped her legs over my lap, and I had wrapped my arms around them. Was that inappropriate, too?

"Yeah, buttface, let go of my legs!" Melanie giggled, and starting waving them in my face. When she did so her shorts rode up even further than they already were and her bare thighs were right next to me. My right arm couldn't help but brush against them.

"Well, get them off of me, you spaz!" I laughed, and started tickling her, right on the bare thigh. It was what was in reach, I had to.

Melanie squealed, and suddenly she was tickling me back. I laughed and tried to defend myself, keenly aware that our mother was still watching us. Always the less cautious one, Melanie climbed onto my lap and straddled me, still trying to tickle my stomach as I tried to tickle her back.

And of course it was inevitable. I was brushing against her perfect breasts nearly every time, copping all sorts of feels as we continued our tickle fight. They jiggled beautifully in my face as she laughed, and as she squirmed on my lap, I felt the heat between her legs rubbing against my cock. It made me instantly hard, a fact that did not go unnoticed.

By Melanie and our mom, both, it seemed.

"Ok, Melanie. Get off your brother," she says quietly. There is an edge to her voice, as there often was these days. "Please don't make me ask you again. I get tired of asking." She turns and walks back into the kitchen without another word.

This time even Melanie stops. Slowly, she lifts her legs and returns to her place by my side on the couch. Her eyes are wide and there is look of surprise and guilt on her face.

"Like I said. I think we need to cool it a bit." I whispered, as softly as I could.

Melanie nodded quickly...and then a smile spread slowly across her face. "Except we're eighteen now. We can do what we want. And besides, I still have to give you your birthday present."

She winked at me, and then suddenly she hopped up off the couch, giving me an excellent view of her perfectly round ass. It was small and firm, and her shorts were still hiked up from our tickle fight, showing me a bit of the bottom curve and sides. I watched it flex as she left the room, and she watched me watch her with a beautiful grin that melted my heart.

To my surprise, she went into the kitchen to help our parents clean up, despite the birthday privilege. Obviously she was trying to get back some of those brownie points we had cashed in today. I decided to follow her.

My sister was so smart and perfect.

Chapter 3

Later that evening, I went upstairs early, claiming a headache. The truth was I was exhausted after the up and downs of the day, and I just wanted to get away from family. Helping our parents in the kitchen only seemed to make things worse with Mom, as she just seemed annoyed that we weren't accepting her hospitality. Personally, I think she had wanted to talk to Dad and we had interfered.

As I lay in bed on my side of the bedroom, wearing nothing tonight but a pair of boxer shorts, I stared at the ceiling and wondered what sort of present my sister had in mind for me. She had already awakened me that morning with a special gift, and I couldn't imagine what more she wanted to do.

Well, I could. But there was no way she meant that. Could she?

I grabbed my phone and began browsing through YouTube, watching videos of nothing in particular to pass the time. Going to sleep was definitely not an option.

About an hour later, I heard footsteps in the hallway outside, and suddenly our bedroom door opened quickly. My sister slipped into the room, shutting the door behind her. And then, suddenly, I heard a "clicking" sound that I recognized, but didn't expect.

Melanie had locked our bedroom door. She had never done that before.

I lie there in the darkness on my side of the room, covered only by the sheet to the waist. My bare chest lay there openly in what I hoped was an appealing manner, my muscles tense as I sat up on one elbow. It was warm today, but that was only an excuse. I wouldn't have worn a shirt to bed tonight for anything. I was surprised I wasn't naked.

Melanie tiptoed over to her side of the room, positioning herself behind the portable screen that divided us. Mom always hated the setup we had in our bedroom and blamed our behavior on how openly we lived. But at the same time, Dad didn't make a lot of money, and we couldn't afford a new house. Sharing a bedroom growing up used to be okay, but we had long since outgrown the appropriateness of that. Now we were forced to make do.

I lie there in bed, listening to my sister strip off her clothes. The sound of her belt clinking together as she stripped off her shorts sent a jolt through my groin, as I realized she was now probably standing there in her panties only a few feet away. My hand slid inside my boxer shorts slowly, and I began gently caressing myself. My penis was extremely sensitive, and it responded to my touch, suddenly swelling in size.

There was darkness for a moment, illuminated slightly by the single window that our large bedroom shared. It was a picture window, the room probably intended as a living area or parlor originally, and Melanie usually kept the curtains drawn. I didn't complain.

And then I heard her footsteps, almost imperceptible to anyone that didn't spend most of their free time in that room, and I knew Melanie was slowly approaching me.

Her shadow blotted out the meager light that the curtains allowed for only a moment, and then her lips were on mine, kissing me passionately. Her tongue plunged into my mouth, aggressively wrestling with my own, and she let out a moan so full of eager desire that I felt my cock stiffen just from the sound of it. She was ravenous, trying to devour as much of my saliva as she could, her hands wrapped into claws around my head like an animal.

I kissed her back, my own hands reaching for her thin body, wanting to pull her close. She quickly climbed on top of me, placing one of her thin legs on either side, straddling me.

It was then that I noticed her legs were bare, and that she was wearing nothing but a thin pair of silk panties and a short sleeved pajama top that hung loose. I let my hands wander up her thighs, around the sensual curve of her hips, and finally up her flat stomach towards the perfect globe of her breasts. As I did so, she suddenly reached over and grabbed the switch on the lamp I keep on the nightstand next to my bed.

"I want to show you something," she said quietly. As she flicked on the light, I realized that the pajama top she was wearing was one of her old ones from when we were younger, and depicted a pink Care Bear with a rainbow on it's stomach and the words "Full of Cheer" printed in childishly block letters. It was far too small for her now, and her breasts stretched the cotton to new lengths it had never known when she was younger. From my angle below her, I could just see the bottom of her perfect breasts.

Her panties were something new she had bought special for the occasion. They were white silk, and printed in blue velvet lettering across the front, over her pussy, were the words "Best Sister Ever."

"Happy birthday, big brother," she whispered to me. "Your birthday present...is me. Now that we're eighteen, we can do whatever we want, right?"

I nodded, letting my hands slide over her stomach, admiring the firmness and creaminess of her young, unblemished skin. There wasn't a freckle or a mole anywhere on her thin body. She was just perfect.

"Well, you could say it back, y'know," she giggles, then slaps my chest.

Say what? I was confused. "I...love you?" I tried. That was usually the correct answer to that.

She laughed. "Yeah, I love you too, ya big, dumb jerk. I meant 'Happy birthday.' Idiot." She slapped my stomach again playfully.

Oh. Duh. "Happy birthday, little sis," I said quickly, and she giggled again.

"You're such a dumbass, bro. That's why I love you." Melanie leaned down and kissed me again on the lips, more romantically this time.

My hands wandered up the sides of her thin waist, enjoying how soft her skin felt. It was like caressing silk, and I couldn't stop moving my hands, wanting to touch every part of her. I reached up inside the small cotton Care Bears shirt and squeezed the perfect globes of her tits again, a perfect fit for my hands.

Melanie's eyes fluttered closed and she let out a yelp as I gently squeezed both of her breasts, her nipples hard and sensitive. I let my thumb trace circles around them, caressing them each softly. Her breasts felt unbelievably soft in my hands, and I needed to taste them, had to taste them. I leaned forward, one arm now around her back, and placed one of her mouth-sized breasts against my tongue. Swirling it around the tip and applying just a little bit of force, I sucked on her nipples, one and then the other, bringing them to hard points. I couldn't help but moan as I did so, it was what I had wanted for so long.

"Ooh, shit....oh Daniel, only you know what I like." She began grinding against my bare stomach, and I could feel her heat and wetness through her silk panties as she brought herself to wetness. I slid the arm that was around her back down and gripped her small, round ass, pulling her closer.

Melanie began to moan softly into my ear as she rubbed herself against me, and my cock grew unbelievably hard inside my boxers. Touching my sister felt so incredibly soft and right, and my hands roamed all over her body with wild abandon.

Suddenly she bent down, placing her face near my crotch, and yanked my boxers down. My erect cock sprang free, hard and pulsing. It was more than ready, and it was obvious what my sister meant to do. I put a hand on her forehead before she could.

"No, baby sis. It's your turn this time. You've always given me that special gift, but like you said, it's your birthday too. Lie down." I gently lowered her back onto the bed.

Melanie obliged, and looked at me with eyes glazed over with lust. I carefully positioned myself at the base of the bed, leaning forward so that my face was comfortably between her legs. I grabbed the hem of her brand-new silk panties and pulled them down, ultimately throwing them off.

And there it was. My sisters pussy. Finally exposed for me after all these years. More than just a place to experiment with or to look at, but being offered up to me willingly to do with as I pleased. To touch and to taste. To fuck.

Melanie spread her legs wide for me and gently caressed her clit for a moment in a circular motion. She had shaved it, and I lowered my lips close to her hairless mound. Her labial lips glistened with newly formed juices, her clitoris red and swollen with arousal. I took a deep breath, inhaling her scent, and was surprised by how much I enjoyed it.

She and I were twins. We were virtually the same person. To love her was to love myself, and there was absolutely nothing wrong with what we were doing.

"Lick it, big brother," my sister whimpered, and I looked up at her face. Her eyes were pleading, desperate for my touch. "Please. I want my birthday present, too..."

I smiled, then looked down at the thin, red slit that was Melanie's pussy. It was glistening now, almost dripping, and as I watched it suddenly pulsed quickly once as if with a life of it's own.

Lowering my face to it, I ran my tongue up the length of her slit. It tasted like salt and honey, and I shivered.

"ahhhh...." Melanie whined, and arched her back. Her hands gripped the sheets on my bed. "Yes, Daniel...."

I let my tongue slurp up her wetness as I spread her lips apart, finally reaching the top. Her clit pulsed in front of me, and I began swirling my tongue around it in a circular motion. She let out a loud moan as she felt the warm wetness touch her most sensitive area, and my nose nuzzled against her stomach, my breath hot on her skin every time I exhaled.

I moaned softly against her mound as I flicked at her clitoris with my tongue, savoring the taste of my little sister's vagina. She was sweeter than I ever imagined, and I wished we had been doing it sooner.

"Oh, Daniel...oh shit, bro....I'm gonna...I'm gonna...!" Melanie was able to shout as she felt her muscles clench over and over, the orgasm finally overwhelming her. She climaxed hard on my face, and while she tried to stifle the cries, there was no stopping the long keening wail that managed to escape around the sides of her hand. Her hips bucked hard, and I did what I could to hold on. Her juices gushed into my mouth, and I suddenly discovered I had a warm, salty mouthful of her cum that I had to swallow.

I pulled away finally as Melanie continued to twitch dramatically. "You can't stop, bro. You can't just lick it. I need...oh shit, bro, I need you..." Her voice was a desperate whine, begging me for more. Her hands reached out and began stroking at my cock. "Please, Daniel. Please. Let's become one."

I looked at Melanie, at the desperation in her eyes. She wanted me now, and there was absolutely no denying her in this moment. My sister, the love of my life, my other half, was burning with the desire to become one with her twin brother. No force on Earth was going to stop us in this moment.

Positioning myself over her thin body, I pushed her bent legs aside and allowed my erect penis to push against her soaking wet mound. She let out a gasp at the sensation, but didn't stop me. Instead she nodded frantically, urging me to penetrate her quickly.

And I did not refuse. Spreading my own thighs wide, I pressed my cock against her slit, and both of us let out a loud gasp as we felt it break her hymen and slip inside. She was tight, unbelievably so, and her vaginal walls clenched so tightly on my cock it was almost painful. She cried out, shouting "Daniel!" loudly, and I responded with an unintelligible groan of sheer pleasure of my own.

It was then that the unthinkable happened. Although I guess we both should have seen it coming.

We both heard it, and yet I didn't stop letting my cock slide in and out of my sister's amazingly tight little pussy. It was too incredible, too pleasurable, that it seemed justifiable that I never stop, no matter what happened.

Mom. She was outside our bedroom door.

And she wasn't just listening either. She was openly knocking on the door. I heard her call out, "Melanie, everything ok?" before the doorknob rattled. She was trying to open the door, and was probably very confused why it was locked.

And yet despite it all, I couldn't stop. I knew I had to, and yet I felt like I was so close with Melanie that I needed to finish first. And so I continued to fuck my sister as our mother pounded on our bedroom door, demanding to be let in.

"ahhh...mmmm...Daniel...." Melanie whispered, trying to bite back the screams so that Mom wouldn't hear. "...We should stop..."

I nodded, but I didn't slow my pace at all. My hips continued to pump into my sister's tight hole as with a life of their own. My cock pulsed and throbbed inside of her, eager to explode.

"Daniel! Melanie! Open the door!" we heard Mom suddenly shout angrily, and she began shaking it, trying to force it open.

"Ahhh!" Melanie cried out, her eyes squeezing shut and her mouth dropping open. "....Ooooh, yes, Daniel, YES....you can't stop...please don't stop..." She was whispering but she was also doing it extremely loudly, so it probably wasn't helping. The feeling of her brother's cock finally inside of her was overwhelming. "Oh Daniel, please...make me cum, make me cum now..."

For my own part I was aware of my mother's angry shouting, but my own orgasm was so close that I was at what seemed like a point of no return. In fact I was so overcome with the incredible sensation of fucking my sister, that I probably wouldn't have stopped even if my mother had burst in right then. It just simply wasn't possible. And so I continued to pound away at Melanie's tight pussy, and my cock began to twitch and throb inside of her.

"....yes, Daniel....give me your cum, brother. I don't care if Mom hears us..." Melanie whispers frantically into my ear, her arms locked around my waist and her hands gripping my ass tightly, driving me deeper. "I want to be one with you..."

I feel my breathing quicken, my sister's breath hot on my ear and her words sending shivers down my spine. My penis responds, and there is sudden, galvanizing tingle through my whole body that seems to focus on my groin in particular. The orgasm is building, and I am still deep inside of her.

Melanie wraps her legs around me tightly, and I feel her pussy begin to clench. She twitches, and suddenly she buries her mouth in my shoulder. "MMMMmmmmm....!" she moans desperately against my flesh, trying with all her might to not scream. Her vaginal walls tighten hard on my cock, and I feel them ripple with the force of her climax and she bucks her hips against me. I make my sister cum powerfully, and I hold her close, lost in the sensation myself. I hear our mother calling our names again one last time before I lose all control.

And then I am lost in my own orgasm. My cock explodes deep inside my sister's vagina, filling her completely with my hot seed, and at the same time I feel the gush of her juices as they spill all over my groin. We cry out in unison, completely oblivious now to the world around us, and there is absolutely no way that our mother cannot hear us now. Our voices mingle and we scream together, and I have never felt so right, so fulfilled, as I did right then shooting my load deep inside my twin sister.

Then it is over. We lie spent together, looking into each other's eyes lovingly. Our mother continued to slam against the door, trying to break it open now. She knew everything and we were caught.

But for now, we simply enjoyed each other.

Our mother is beyond angry now I haven't seen Melanie in about two months, but at that moment in time we were one. It was the last happy moment I can remember.

It was the last time I ever felt complete. The last time I ever felt whole. It was last time in my life that I felt any reason to live.

A twin cannot live without with their other half.
