When I pushed open the door just after midnight, the house was dim and quiet, except for the blue flicker of the TV bleeding out from the living room. I still smelled like perfume and sweat—Lena’s bedsheets had clung to my skin longer than I expected. I was half hoping to sneak past everyone and shower off the evening, but then I caught the curve of a familiar silhouette on the couch.
My sister.
Emma.
She was curled into herself like a question mark, a big floral throw bunched around her shoulders but not doing much to hide the fact that she was in just a faded lavender nightie, the straps sliding off one broad shoulder. The kind of worn cotton that hugs in all the places you pretend it doesn’t. Her full arms were crossed tightly over her belly, and the neckline of that nightie dipped just enough for me to catch the rise of her soft cleavage, her chest gently rising and falling as she sniffled at something playing on the screen.
“Em?” I stepped closer, dropping my keys onto the counter, voice low. “You alright?”
She jumped a little, wiping at her eyes. “Jesus, you scared me.”
“Didn’t mean to,” I said, toeing off my sneakers, moving toward the couch. “Where’s Mum?”
“Out playing bingo,” she said flatly, eyes back on the screen, but not really watching. “She asked me to come but I didn’t feel like being stared at by a room full of old ladies judging my second piece of cake.”
I lowered myself onto the other side of the couch, giving her space. “You want me to go grab you a third piece then? Just to piss ‘em off?”
She huffed a laugh through her nose, but it didn’t really lift her face. Her hair was down, thick and frizzy from whatever half-hearted bun she’d tried to wrestle it into. She looked warm and tired. Still crying a little, even though she was trying to play it cool. Her cheeks blotchy. Skin damp.
“It’s not funny,” she said. “I just… I looked at myself in the mirror after brushing my teeth and… I dunno. I hated everything I saw.”
I glanced over at her. The nightie was bunched at her hips where her thighs spread naturally on the cushions. Soft. Pale. Real. Her whole body took up space, and there was something about the way she kept tugging the fabric down like it might disappear if she just tried hard enough.
“I’ve had nights like that,” I said, leaning my head back. “Not exactly the same, but you know. Nights where I feel like I’m wearing the wrong skin.”
“Yeah, but you still get to walk around like you’re a damn Calvin Klein model who fucks on demand.”
“That’s not fair.” I looked at her. “I mean, yeah, I’m good-looking—”
She rolled her eyes, but her lips twitched.
“—but that doesn’t mean I don’t get in my head too.”
“Still,” she said, almost whispering now. “No one looks at me and wants me. Not the way they look at you.”
I hesitated. Watched her pull the blanket tighter over her middle, but the cotton of her nightie still clung to the swell of her hips, the soft curve of her belly pressing against the fabric. Her thighs shifted slightly as she adjusted, and the couch creaked beneath her weight. Her cleavage stood out her huge tits.
“Hey,” I said, leaning forward, my elbows on my knees. “You know you’re beautiful, right?”
She made a sound—half a scoff, half a sob. “Don’t patronize me.”
“I’m not.” I looked her dead in the eye. “You’re beautiful. Like… real. You’ve got softness in places people crave. You’ve got curves that could kill a man. Don’t you see how stunning you are just sitting here? Jesus, Em. You in that nightie, damn you look really good. You may be a big girl but your tits are better than mums.”
“Omg Carl, you seen mums tits,” she said as her mouth dropped.
I laughed, shaking my head. “Yeah, I have, Em. And trust me, yours are way better. They’re… fuller. Softer. They have this… natural bounce to them that just… ugh, it’s amazing.”
She blushed, looking down at her chest. “Stop it, Carl.”
“I’m serious,” I said, leaning in closer. “I’ve seen a lot of tits, Em, and yours are top-notch. They’re fucking perfect.”
She looked up at me, her eyes wide and a little wet. “You really think so?”
“I know so,” I said, holding her gaze. “And not just your tits. Your whole body is gorgeous. You’re a fucking goddess, Em. Don’t ever doubt that.”
She sniffled, wiping at her eyes again. “I just… I feel so lonely sometimes. Like no one will ever want me.”
“I want you, Em,” I said, my voice low and earnest. “I’ve always wanted you.”
She stared at me, her breath quickening. “Carl… what are you saying?”
“I’m saying that you’re beautiful, Em. Inside and out. And I want to show you just how much I desire you.”
Her cheeks flushed, and she bit her lip nervously. “But… I’m a virgin. I am fat. Also, you are my brother.”
I smiled gently, reaching out to cup her cheek. “I know, Em. And that’s okay. I want to be your first. I want to show you how beautiful sex can be.”
She looked into my eyes, her own filled with a mix of desire and uncertainty. “But… what if I’m not good at it? What if I don’t know what to do?”
“Then I’ll teach you, Em,” I murmured, my thumb stroking the soft skin of her cheek. Her skin was warm, a little damp from her tears, but now a different kind of heat was rising. “You don’t have to know anything. Just lay on the couch and enjoy it.”
I moved the blanket off of her as her heavy body laid down. Her nightie rode up and I could see her red panties barely covering her big fat pussy. Her face red with embarrassment as she lift her fat ass up a bit to slide her panties off. I undid my jeans and slipped them off with my boxers. Shit she was a virgin to so this was going to be messy and break her hymen.
As I positioned myself between her legs, I could feel the heat radiating from her body. She was trembling slightly, her eyes wide with a mixture of fear and anticipation. I leaned down and kissed her softly on the lips, trying to calm her nerves.
“It’s okay, Em,” I whispered against her mouth. “I’ll be gentle with you.”
She nodded, her breath hitching as I moved my lips down to her neck, trailing soft kisses along her collarbone. Her skin was so soft, so warm, and I couldn’t help but be aroused by her. I knew this was wrong on so many levels, but I couldn’t deny the feelings that had been building inside me for years.
I slowly made my way down to her breasts, cupping them in my hands and gently massaging them. Her nipples were already hard, poking through the thin fabric of her nightie. I pulled the material down, revealing her full, heavy breasts. They were even more beautiful than I had imagined, with rosy nipples that begged to be sucked.
I took one of her nipples into my mouth, swirling my tongue around it while my hand continued to knead her other breast. She moaned softly, her hands finding their way into my hair as she arched her back, pushing her breast further into my mouth.
As I moved my attention to her other breast, I could feel her getting wetter. I could smell her arousal, a heady mixture of sweat and desire that only fueled my own. I trailed my fingers down her belly, feeling the softness of her skin beneath my touch.
When I reached the apex of her thighs, I hesitated for a moment, unsure of how to proceed. This was her first time, after all, and I wanted to make it as pleasurable as possible for her. I gently parted her folds, revealing her swollen clit.
I began to massage it in slow, circular motions, feeling her hips buck up against my hand. She moaned louder now, her fingers digging into my scalp as she writhed beneath me. I continued to tease her clit, feeling her wetness seep onto my fingers.
I knew it was time to take things further. I positioned myself at her entrance, my cock throbbing with anticipation. I looked into her eyes, searching for any signs of hesitation or fear. All I saw was desire.
“I’m ready, Carl,” she whispered, her voice trembling with need. She looked at my big dick, “This is going to hurt isn’t it Carl.”
“A little, maybe, at first, Em,” I admitted, my voice rough with desire. “But only for a second. I promise I’ll be gentle. We’ll go slow. My cock will break your hymen.”
I eased forward, pressing the head of my cock against her slick entrance. Her breath hitched, and her hands gripped my shoulders, nails digging in slightly. I looked down at her face, seeing the tension, the slight wince already forming.
“Just breathe with me, Em,” I murmured, my voice a low rumble. I pushed an inch, feeling the sticky resistance, the tight embrace of her virgin flesh. A small gasp escaped her lips, and her eyes squeezed shut.
“It’s okay,” I repeated, pressing a soft kiss to her forehead. “Just a little more.”
With another slow, steady push, I felt the definite give, a sudden tearing sensation that caused her to cry out, a sharp, choked sound. Her body stiffened violently, a silent scream caught in her throat, and a tremor ran through her. I paused, letting her adjust, feeling the immediate wetness and warmth of her blood seeping around me.
“Shh, shh, it’s done,” I whispered, rubbing her hip soothingly. “See? You’re okay. It’s over now.”
Her eyes fluttered open, still wide, but the raw pain was already receding, replaced by something else – a dazed wonder, a faint flush of new sensation. She let out a shaky breath, her body slowly relaxing around me, a new kind of tightness, a delicious friction.
I waited, letting her get used to the strange fullness, the aching stretch. Her fingers, no longer digging into my shoulders, now kneaded the taut muscles of my back.
“Carl,” she whimpered, her voice raspy, a low moan forming in her throat as I began to slowly, carefully, withdraw and then push back in. The initial pain was gone, replaced by a deep, new ache that spread through her core.
“That’s it,” I encouraged, moving with deliberate slowness, letting her body learn mine. Each slow thrust brought a new sensation, a deeper stretch. The couch creaked beneath us with the rhythm of our movements. Her hips began to lift slightly, meeting me, an instinctive response.
Her eyes were fixed on mine, a raw vulnerability in their depths, mixed with a growing intensity. Her earlier tears were long forgotten, washed away by this new, overwhelming tide. I watched her face, seeing the subtle shifts from apprehension to a growing pleasure. Her soft lips parted, and soft groans began to escape, quiet at first, then growing louder, more urgent.
“Oh, God, Carl,” she gasped, her hands now clutching my hair, pulling my face closer. Her nails raked lightly down my back, guiding me, urging me deeper, faster.
I picked up the pace, my movements becoming more confident, more powerful. The scent of our combined arousal filled the dim living room, sweat and the metallic tang of fresh blood mingling with Emma’s natural, warm smell. Her large breasts bounced with each thrust, the nipples that I had teased earlier now stiff and dark.
She arched her back, her thick thighs wrapping around my waist, pulling me impossibly closer. Her sounds grew louder, a desperate litany of moans and choked cries. “Yes! Oh, Carl, yes!”
I felt her internal muscles clenching around me, a delicious, milking sensation that drove me to the brink. Her breathing grew shallow, ragged, and her body began to tremble again, a different kind of tremor this time.
“You’re so beautiful, Em,” I whispered against her ear, pushing deep, feeling her clench violently around me. “Just like this. Perfect.”
With a final, shattering thrust, she cried out, a long, drawn-out wail as her body convulsed around me, her hips bucking repeatedly. I felt her release wash over me, the sweet, powerful contractions, and then, unable to hold back any longer, I let myself go, spilling deep inside her, groaning her name as the world dissolved into a rush of pure, primal sensation.
We lay there for a long moment, tangled together on the couch, the blue flicker of the TV still playing silently in the background. Her heavy body was warm and soft against mine, her breath ragged in my ear. The silence of the house was broken only by our ragged breathing and the distant hum of the refrigerator.
She stirred slightly, her cheek rubbing against my shoulder. “Carl?” she whispered, her voice rough with exhaustion and something new, something profound.
“Hmm?” I hummed, too spent to move.
“Are we… are we really doing this?”
I held her tighter, pressing a kiss to her damp hair. “Yeah, Em,” I murmured. “I think we are.”
