"I'm not mad. I just wanna know why you did it."

My niece avoided my gaze, looking like a kid caught with their hand in the cookie jar. She had dropped my panties which she had taken from the laundry pile, the thing that got us into this whole confrontation in the first place.

After what felt like a full minute of silence, she answered me, still not meeting my eye. "Because Mom had the same pair."

Because… what? "That hardly seems like a good reason."

"Well it's why I did it," she snapped back, her shoulders tense. I winced. I was making things worse.

She had always been a tough kid, but since she started living with me after the accident, she was more like cracked, splintered glass. Sharp enough to cut but one wrong move away from shattering and crumbling to the ground. It didn't help that she had to look her dead mother's identical twin in the face every day.

Even as adults, we shared the same face, the same soft features. Our brunette hair was styled the same way, if you could even call it styling since neither of us could be bothered to do anything more than brush it out in the morning. Even our figures were pretty much identical, both of us maintaining the same curves we had in our youth. We were truly impossible to tell apart.

"I'm sorry. That came out wrong," I said gently. "I just didn't see how that was relevant."

She may have been taller than me, but in that moment, it seemed like I towered over her. It was as if she was a child again, shy and unable to speak. "I don't know if she told you," she finally said. "We weren't meant to tell anyone but you're her twin and there might have been some twin code or whatever, but Mom and I… we used to… you know…"

"You used to…?" I egged her on, having no idea what she was talking about.

"…sleep together."

"Oh."

No, that wasn't something my sister had ever mentioned. She had always brought home more women than me in our youth, and there were several times where she invited me to join them, so in hindsight, the incest shouldn't have come as such a surprise. But it still caught me off guard and I needed a second to process it. A second too long, which must have convinced her that I was taking it badly.

"You're mad, aren't you?"

Was I? Not particularly. Just confused. Curious even. I wonder if I would have reacted differently if I found out when my sister was alive.

"No. No, I'm not mad, sweetie," I calmly reassured her, while at the same time wracking my brain for something else to say. My eyes swept over her and I noticed the slight bulge in her shorts. In the time since she'd been living with me, she'd kept it well hidden, but considering what I found her with and what I found out, the erection made sense. "You must miss her a lot," I finally said.

She tried to laugh, but it was more like a swift expulsion of air. "That's an understatement."

"I know it's not easy being here," I continued to acknowledge. There was that same dry laugh.

"You have no idea."

"I have more of an idea than you think." I took a small step closer to her. "When you were little, you didn't see much of me since I lived pretty far, but your mom and I have always been close. And now that… Now it's like I see her every time I look in the mirror. I know you feel the same way when you look at me."

Our eyes met for the first time since I caught her. "I hate seeing you like this, sweetheart."

"Sorry."

"You don't need to apologise!" I said quickly. "Look, I know this is a little weird, and you don't need to agree to it, but I want to help you feel better. And there are more effective ways of doing that than stealing my underwear." I took another step closer to her. Our faces were barely an inch apart, even if I did have to look up a little to see her.

She blushed, suddenly realising what I was suggesting. Her eyes widened slightly. "You mean you want to… with me?"

"I want to make you feel better. In any way that I can."

"You'd do that for me?"

I reached out to gently cup her cheek and she leaned into my hand. "Oh, sweetheart, I'd do anything for you."

Her expression was pained, but she didn't stop me when I closed that final inch of space between us, capturing her lips with mine. She whimpered, her eyes shutting before opening again, taking me in. My hands dropped from her face to her waist, feeling the warmth of her skin beneath my fingertips. Our kiss started tender and wary, but grew more intense with each passing second. I trapped her bottom lip between my teeth, making her gasp. She cradled the back of my neck, other hand hovering undecidedly.

"Don't hold back," I paused to say, our foreheads touching. "Do to me what you'd do to her."

Her eyes fluttered shut as we kissed again. At the same time, her other hand finally found its place on the small of my back, just above my ass. I desperately wanted it to be lower.

"Your room or mine?" she murmured. I said nothing, instead leading her towards my bedroom, our lips never parting. Somehow, we managed to shed most of our clothes along the way. By the time we reached my room, I had lost my shirt and she was down to her bra and boxers. She walked backwards and I reached around her to open the door. The breath was swept from her as I pinned her down onto my bed, the mattress sinking under us.

My body blocked the light, casting her face half in shadow. She gazed up at me, eyes wide and with a look I couldn't read. "You look just like her."

I stroked her cheek lovingly, leaning down to kiss her again. This time, her hands finally found my ass, feeling me up through my jeans. It sent a rush of wetness between my legs.

"Tell me what you want."

She opened her mouth and closed it again, her hesitation obvious.

"Don't hold back," I reiterated with an intense gaze.

"I, um…" She swallowed. "I want you to touch me."

"Where?" I pressed. If we were really doing this, I needed her to be all in. I needed her to be the one to say it.

A ragged breath rose from her throat but she said no words. Instead, her actions did the talking, taking my hand and leading it down to her boxers. I cupped her length through the fabric, eliciting a sharp exhale from her.

She raised her hips slightly, pulling down her boxers and kicking them aside so there were no barriers between us. I could feel her throbbing shaft in my hand, so thick that my fingers couldn't touch when I wrapped my hand around it. I watched her face contort with pleasure at the first stroke, teeth biting down on her lower lip.

I jerked her off with more speed, using the wetness leaking from her cock to ease the process. At the same time, her hands roamed up my body, pausing at the clasp of my bra.

"Is this okay?"

I nodded, feeling the ghost of her fingertips itching to unclasp it. "Please."

One snap and the bra fell away, freeing my breasts. Her eyes widened and she looked at them as if she couldn't bear to take her eyes away. The way I was leaning over her meant they were practically at eye level, and I felt so much more exposed. A blush spread across my face and down to my chest, as it always did when I was embarrassed, and I focused instead on the movement of my hands so I wouldn't be distracted. Her tongue chased that blush, licking a path from my jawline down the centre of my cleavage. It felt like a trail of fire on my skin.

I whimpered when she sucked a mark on my left breast, just shy of my nipple. That made me grip her cock harder, feeling her shaft pulse under my touch. Her hand reached out to grope my other boob. They weren't the largest – I'm sure they couldn't compare to my sister's, especially after she had a kid – but one touch and her eyes snapped shut, a hiss slipping past her lips.

"Fuck," she cursed, hips jerking wildly under me. Her breath stuttered, sounding like music to my ears. Ropes of cum wet my hand, some even reaching as far as her chest, missing her bra and instead dripping down into her cleavage. Once her orgasm ceased, she looked sheepish. "Sorry. It's been a while."

I didn't really have an answer to that. If my sister had been the last person she slept with, it would have been way more than a while. Closer to a year. Her quick release was more than justified. My eyes fell on her chest and I leaned over to lick up the cum that had fallen there. The thick white seed coated my tongue. Its taste was addictive.

She shuddered, stripping herself of her bra so I had more access. I took my time, tracing my tongue through her cleavage and down her stomach until I finally reached her cock, flaccid for now but quickly getting hard once again. At this position, I was able to appreciate its size in all of its glory. Longer and thicker than any dildo I'd ever used. I didn't even need to think before I took it down my throat.

Her hands grabbed my hair roughly, just a hint of pain biting at my scalp as she guided me up and down her length. My throat quickly relaxed, taking her more easily. I tried to recall past conversations with my sister. She wasn't one to shy away from sex talk, even when we were past our youth, and she frequently described her nights of passion to me whether or not I wanted to hear about them. The realisation dawned on me that towards the end, that elusive partner she described must have been her daughter.

"She loves blowjobs," she had said, her body draped over the armrest of my couch. "Real messy ones too. Sometimes the whole bottom half of my face is wet."

"Why would she like blowjobs? Not like she can feel it," I had questioned, assuming she was talking about a dildo.

My sister had snorted, her nose crinkling the same way mine did when I laughed. "Oh yeah. Right."

I should have definitely realised they had been sleeping together earlier.

Lewd gagging noises filled the room as her cock hit the back of my throat over and over again. Her shaft was wet with a mixture of cum and spit, and when I paused for breath, my cheeks and chin were the same. I took great pleasure in licking her veiny length, feeling each bump beneath my tongue. She never took her eyes off me, and I noticed them drop from my mouth to my chest.

"Sometimes I feel like I'm not doing enough, you know?" I had said to her mother in that same conversation. "I'm not the biggest fan of anal, and while my oral game is okay, I don't know what else there is."

She had gestured to my chest. "You have tits, don't you? Don't forget to use them."

Only thirteen minutes older than me, and yet she was full of sage wisdom.

"Oh God," my niece groaned, her eyes rolling back in pleasure when I pillowed her cock between my breasts. I squeezed my tits together, rubbing them up and down her shaft. To my surprise, a few inches poked out the top, and I leaned over to lick what I could, making her hips buck.

"That feels so good," she praised, reaching forward to pinch my nipples. Jolts of pleasure shot through me at her encouragement. I could feel my own slick wetness, sticky on the insides of my thighs.

I continued to give her the best titfuck I could, hoping I could live up to whatever her mother had done. From how she trembled and gripped the sheets, I had the sense that I was doing a good job. Just when I thought she was going to blow again, she stopped me.

"Hang on," she stammered. "Not yet."

I stopped immediately, pulling away. Her cock twitched helplessly at the loss of contact, and it took all my willpower not to just take things into my own hands and bring her to orgasm right away.

"I wanna cum inside you," she explained, her voice still tinted with uncertainty.

I smiled. "I want that too." And I was on the pill, so there was nothing to worry about on that front.

"But I wanna taste you first," she continued, biting back a shy grin. After I got out of my jeans and panties, I let her guide me as she wished until I was poised to sit on her face, my legs bracketing her head. Her hands gripped my ass, squeezing it in her palms and making me gasp. I held the headboard for support and lowered myself down until I could finally feel the heat of her breath against my lower lips. My eyes rolled back and my back bowed at the first lick.

Her tongue explored me fully, tracing my outer lips before doing a deep dive. Even the feeling of the muscle just barely entering me had me gripping her hair to pull her closer. I moaned, grinding my hips down on her face and extracting every ounce of pleasure that I could.

She watched me keenly from below, big doe eyes noting every subtle action she did, keeping track of which ones got a stronger reaction out of me. Her teeth scraped my clit and I yelped, biting my lower lip.

"Sensitive?" she teased, the tip of her tongue tracing around the erect nub.

"Mhm."

A low laugh rose from her throat, and I barely had time to register it before she took my clit between her lips and sucked.

"Yes!" I cried, throwing my head back. "Don't stop…" I almost wanted to comment on how lucky her mother must have been to receive this kind of sinful treatment, but I held back because I wasn't sure how she'd take it. Hell, I wasn't even sure how I'd take it. I didn't know how to interpret the dull ache in my chest. So I just let her continue.

She reached up to cup my breasts, toying with my nipples between her fingers. Her skills were unmatched. She was doing everything she could to take me apart and it was working. I felt myself racing towards my imminent climax, one that would no doubt leave me breathless.

My clit was still trapped between her lips, and her tongue began to lavish it with hard licks, sending me over the edge. I rolled my hips and cried out, fisting the sheets under us with a white-knuckled grip. Fireworks went off in my head when I came, colours bursting in my mind's eye as I felt a rush of liquid gush from my pussy, loud enough that I could make it out over the sounds of my pleasure.

She just kept going, her movements less intense now. Her tongue brushed against my centre in big, broad strokes, a stark contrast to the speed and intensity with which she devoured me earlier. My orgasm gradually reached its end and I came down to the feeling of her lazily licking me, the duller pleasure providing a much needed moment of respite.

Eventually, I rolled off her, my limbs jelly as I collapsed next to her. Her face was a wet mess, the entire lower half soaked. She looked at me, her smile half smug, half sad. "Yeah, Mom was a squirter too."

"I, uh… I didn't know I was one," I admitted breathlessly.

Her eyes widened in surprise. "Seriously?"

"Seriously."

"I guess that means I did a good job."

I kissed her tenderly. "The best job."

Our lips met clumsily as she rolled me onto my back, pinning me underneath her. Her skin was hot against mine, our bodies slightly slick with sweat. I pulled her closer, unable to get enough of her touch. The light shone behind her head like a halo, casting her in an angelic glow.

My niece spread my thighs and leaned forward, filling me with every inch of her. I sighed with pleasure, her cock penetrating me deeply.

"Fuck," she muttered. "You feel just like her."

I tried to picture how my sister would have reacted, imitating what I thought was the exact way she threw her head back and moaned or clung to her daughter's shoulders. From the bittersweet look on my niece's face, my guesswork seemed to be paying off.

Every recent conversation I'd had with my sister that had any mention of sex played in my head. I analysed each one, picking them for any small detail I could get.

"Do you have a nail clipper?" my sister had asked me once.

"Why do you need it?" I'd questioned when I handed it to her.

She had a sly grin on her face. "Date night. Might end up in the bedroom and apparently my nails are like cat claws. Red scratch marks are hot and everything, but I'm not looking to draw blood tonight."

I raked my nails down her back, noting the hiss of her breath in my ear. She thrust into me faster, her balls rhythmically hitting my ass. It was a shame that her mother had loved anal when that was something I wasn't too fond of. Maybe it was something I could try again in time.

"Oh God!" I cried when she added a little twist to her hip with each thrust. "Fuck, so deep…"

"Mommy…" she whimpered before her voice quickly cut off and we both froze. We stared at each other. Her eyes were glassy.

I should have expected the slip up. After all, I was doing this to remind her of her mother and the intimate relationship they'd shared. Or at least it started that way. We might have been carbon copies of one another, but I would always know that my niece was thinking of her mother while she fucked me. That shouldn't have stung. And yet…

"You can call me whatever you want, sweetheart," I told her, my voice soft. I reminded myself that I was doing all this for her. It didn't matter that she was thinking of someone else.

I couldn't bring her mother back. I couldn't stop her pain. But I could at least give her this.

She looked unsure, so I began moving underneath her to ease her worries, unable to look her in the eye. Getting the hint, she continued like we'd never stopped, fucking me with such force that the bed underneath us creaked.

She lifted one of my legs so it was raised over her shoulder, allowing her cock to hit at a new, blissfully pleasurable angle. I got a full view of her defined abs as she worked her magic, still wet from where I had lapped up her cum. I licked my lips, already thinking of the next time I could do it again. Then, I saw her expression, looking at me like I was the most incredible thing she'd ever laid her eyes on. That same ache hit when I knew she wasn't seeing me.

She was seeing her.

"Hair pulling," my sister had confessed one night, the two of us way too deep into our forth bottle of wine. "Especially doggystyle. That's top tier stuff. You can never go wrong."

"P-please," I begged. "Take me from behind."

She growled, something animalistic rising in her sending shudders deep to my core. Without hesitation, she flipped me onto my front before mounting me like a dog in the heat. The wind was knocked out of me as she pressed me down into the bed, my weight barely supported on my shaky elbows. Her cock rammed into me, the lewd slapping noises filling the room along with her dirty talk.

"Take my cock, Mommy," she muttered. "Fuck, you're so wet. Wet from your own daughter fucking you."

Her voice was soft, definitely softer than it would be if she was fucking her mother. Those words weren't meant for me, but they hit me all the same. I was being fucked by my niece. My own flesh and blood. I should have never suggested this. It should have filled me with shame. But it didn't. It just made me long for my next climax.

"Touch me," I panted, needing just a bit more to finish.

She obliged, her hand snaking between my legs and quickly finding my slippery clit, its sensitivity making my arms give out until I was lying flat with her on top of me. Her lips sucked more hickeys onto my neck and the backs of my shoulders as her fingers drew even more pleasure from me, pressing and tweaking and rubbing until I came.

The pillows muffled my screams of pleasure as my orgasm came crashing down. Those same bursts of colour flared behind my eyelids, the release so powerful it was practically dizzying. I thrashed under her like a wild beast she was trying to tame. My pussy spasmed around her dick, and the slight shift in her moans signalled to me that she was close.

"I'm gonna cum inside you," she groaned, pressing into me harder.

"Please do…"

Her hips stuttered and then stilled with a final forceful thrust. I whimpered as I felt her shoot her seed inside of me, each rope hitting so deep. Her fingers stopped moving, just resting between my legs as our bodies stilled and we came down from our respective highs. I could feel her heartbeat against my back, feel her cum leaking out of me and pooling between my legs.

"Thank you," she whispered, her cheeks wet against my skin. "Thank you."

"Shh, it's okay, baby." I rolled us over, sighing as she slipped out of me before cradling her, holding her close. My hand rubbed small comforting circles on her back, soothing her. She buried her face in my neck and I felt a sting behind my eyes. "You're okay."
