Chapter 4: Twin Sisters’ Anal Delight

Note: Thanks to wrc264 for beta reading this!

“Come on, onee-chan,” a voice called as I walked with my friend through the streets of Tokyo. “Get up.”

The laughter around me abruptly ended as my eyes opened. The dream faded away. I wasn’t in Tokyo but staring at my naked twin sister kneeling over me on our futon. I blinked, sleep falling away from me. My eyes felt so heavy. I let out a mewling sound, wanting to go back to sleep. I wiggled my hips. There was something in my butt. Thick. A cone.

“Onee-sama?” I muttered, confused by why she was naked. Why I was naked. “What?”

“Okaasan just got out of the shower,” she said. “Come on.”

Why did it matter that our mother got out of the shower. What was in my... ?

A butt plug.

Yesterday flooded back to me. Lee seducing us into lesbian incest ... Losing my virginity to Clint ... Our naughty double-headed dildo play on the couch beneath our mother’s nose ... Then Kimiko and I retired to our bedroom and did more naughty acts until I passed out in a sticky haze of pussy juices pressed against my twin.

We just had such a wild time. It was crazy. How did we get into this situation? Clint and his family.

My sister’s desire to have an older brother to have sex with had led her to meeting Clint’s older sister Zoey on the internet. This older girl put all these ideas into my fourteen-year-old twin sister’s head. When we moved to California, through the strangest twist of fate, we moved into the same city as Clint’s family and Kimiko pushed our mother into buying a house for sale on Clint’s street.

It was all downhill after that. My sister led and I followed. I always followed. Though we were twins, she was technically older than me. I always deferred to her and now ... Now I obeyed her orders. I did what she said. I had sex with her, with Clint’s sister, and with Clint himself.

I lost my cherry to the young man, our surrogate big brother.

“Okay, onee-sama,” I muttered in our native Japanese. I didn’t fight as my sister hauled me to my feet.

My small breasts jiggled before me, identical to those small mounds budding on my sister’s chest. Her dark-olive nipples were hard, puckering from her areolas, and her black bush glistened with passion between her pale-olive thighs. She gripped my hand and led me to the door. Naked.

I wanted to whine, to protest that our mother could catch us, but I knew it was pointless. My sister wouldn’t care. It would only turn her on. She was all about taking risks around our mom. Because she wanted to seduce our mom.

And Clint’s family would help.

Kimiko pushed her head out our door, doing a quick look, then she darted out into the hallway. I followed after, the butt plug shifting around in my asshole. It made me whimper, sending tingling heat rushing to my pussy. My heart beat faster. We were in the hallway. Exposed.

I heard Mom moving downstairs as we rushed for the hallway, our bare feet padding on the carpet. My sister reached the door and crashed through it, hauling me into the Western-style bathroom. I closed the door behind us, locking it.

Western-style bathrooms had the toilets in the same room as the bathtub and shower. They didn’t even have a shower station, a place to wash your body before you slipped into the tub to soak and relax. Instead, it was combined into one tub. It was more space efficient, but ... The tub was so small. I couldn’t fit in there with my sister and have us both be comfortable.

Did Americans not share baths?

“Why was it so important that we get in here after mom, onee-sama?” I asked as my sister went right for the clothes hamper.

She threw it open and snagged something. She whipped around, her black hair sweeping about her shoulders as she faced me. She held a pair of cream panties in her hand, holding it between her fingers. I’d never seen it before. It wasn’t mine or my twin’s.

“Why do you have okaasan’s panties?” I asked. “Minako thinks that’s weird.” I always referred to myself in the third person. It just felt so weird using the pronoun “I.” Kimiko claimed I did it to sound like a cute, little sister for the big brother I secretly craved.

And ... she might be right.

“Because these were on her all night long, onee-chan,” she answered, bringing the crotch to her mouth. She shivered, inhaling, her small breasts jiggling. “You can smell her. Her pussy. Mmm, it’s delicious.”

My sister pulled our mother’s panties from her mouth, a look of absolute joy flashing across her expression. Then she shoved them into my face. The cotton rubbed across my lips and nose. She clamped it about me like a rag. I felt like she was trying to kidnap me, smothering me with chloroform or something.

“Breathe it in, onee-chan,” she groaned, a shudder to her word. “Just inhale. Mother smells delicious.”

I had to breathe. I couldn’t stop myself and ... I smelled a spicy musk. Not the same as our tangy passion, a different flavor. A surge of heat rushed out of my pussy as I inhaled again. A deep one. I filled my lungs, drawing in as much air as I could through my nose.

“You like it, don’t you?” purred Kimiko. She pressed her body against my back, her nipples hard, her bush tickling my rump. “The smell of our mother? It turns you on, doesn’t it, sister-slut?”

I only moaned in answer, my body shuddering. Mother did smell so delicious. I closed my eyes, reveling in the spicy scent. My body quivered. My hand grabbed the panties, holding them to my face. My eyes fluttered. It was so wrong to do this. To smell our mother’s panties. I felt so naughty.

My sister’s hands roamed my body. She cupped my small titties with both her hands, squeezing and kneading them. Her thumbs swept across my areolas and nipples. She rubbed them, pressing them into my breasts. It made me ache and throb. I whimpered into our mother’s panties, heat blossoming between my thighs.

“Mmm, yes, yes, that’s it, my sister-slut, just rub okaasan’s panties on your face,” she moaned. “Is it making your cunt wet?”

“Yes, onee-sama,” I whimpered, my asshole clenching around the butt plug. Cream ran down my thighs, my pussy on fire. “Minako is such a wicked slut for getting so turned on by okaasan’s panties.”

“Yes, you are,” moaned my twin. Her hands squeezed my tits then they moved. I shuddered as one slid down to my stomach, caressing me with hot fingers. “Just a filthy, little lesbian whore for getting turned on by okaasan.”

Her hand slid past my bellybutton, circling my little divot, and finding the silky curls of my pubic hair. I shuddered as she danced through my curls, caressing me, making me squirm and tremble. I whimpered, my body shivering at the feel of her naughty touch.

I gasped as she reached my pussy lips. She stroked up and down my slit. I rubbed our mother’s panties tighter against my face, taking another whiff as her fingers danced along my juicy labia. My bowels squeezed around the butt plug as pleasure stirred through me.

Her other hand swept around my hips and between our bodies. She groped my rump, squeezing my butt-cheeks. Her fingers dipped into my crack while her other digits stroked my clit. I shuddered against her as she slid them down through my ass-crack and found the knob of the butt plug.

“Onee-sama!” I gasped as she seized the knob of my butt plug and pushed the cone-shaped toy deeper into my rectum. A hot pleasure radiated out from my bowels, meeting the delight brimming in my pussy.

“Mmm, you like that, sister-slut?” she purred into my ear, her nipples so hard on my back. “You like it when I play with your cunt and asshole? Huh? While you’re reveling in the smell of okaasan’s panties.”

“Minako does, onee-sama,” I whimpered.

Her fingers danced on my clit while she worked the butt plug in and out of my asshole. I gasped and shuddered as the cone would pop out of my sphincter then she would shove it back in, stretching out my anal ring over and over. My toes curled against the cold tiles of the floor. I whimpered, the sounds echoing around us.

My eyes squeezed shut as I shuddered. My juices flowed as her fingers massaged my clit. She nibbled on my ear as I groaned into our mother’s panties. My every inhalation full of that spicy, incestuous musk.

My tongue lapped out, dragging across the cotton. I shuddered, tasting our mother now. I was indirectly licking her pussy. Doing something so wicked and nasty. I whimpered and shuddered, my pussy clenching. Juices ran down my thighs as I whimpered out in rapture. It was incredibly nasty.

It made my pussy burn and my asshole ache.

My sister pumped the butt plug faster and faster in and out of my sphincter. The velvety friction sent waves of burning heat soaking into my cunt. My juices flowed around her fingers. The cream dribbled down my thighs.

“Onee-sama,” I moaned between licks, the spicy flavor, lingering with cotton, staining my tongue. “Minako is going to ... to...”

“To cum like the slut-sister she is?” my twin purred, her fingers rubbing harder and harder on my clit.

“Yes!” My pussy clenched.

She jammed her fingers deep into my cunt, pushing the butt plug hard into my rectum. I gasped at the sudden intrusion. The silky plunge of her fingers into my juicy snatch had me shivering. I trembled, my heart pounding in my chest. I groaned, my eyes squeezing shut, the pleasure rippling through my body.

My holes squeezed down on the sex toy and her fingers. The dual frictions mixed and swirled in me. I shivered, my mouth sucking on our mother’s panties. My hungry lips worked out every drop of her spicy flavor. I squeezed my eyes shut.

“Yes, yes, yes!” I whimpered. “Minako ... Minako is such a slut!”

“My slut!” my twin moaned, her two fingers burying deep into me.

Her words set me off. My orgasm exploded in the depths of my cunt. My pussy writhed. My body bucked. Pleasure surged through me. Wave after wave of rapture buffeted my body. I whimpered and groaned, my eyes squeezing shut. The pleasure crashed through me. Wave after wave of bliss inundated my mind.

It was incredible. Amazing. I loved it. I moaned into our mother’s panties as my cunt spasmed about my twin’s fingers. My asshole writhed about the butt plug. I bucked and trembled, stars flashing across my vision as the bliss inundated my mind.

“Mmm, yes, yes, yes, you sound so cute when you cum, onee-chan.”

“Thank you, onee-sama!” I moaned as the pleasure rippled through me. The heat drowned my mind in ecstasy. “Minako loves cumming!”

“The way every slut-sister does.”

I whimpered and groaned, my entire body buzzing as my orgasm peaked. It dissolved into humming rapture. I trembled, leaning back into my sister. Her mouth nibbled on my neck. I loved the afterglow.

I dropped our mother’s panties, soaked by my saliva, into the hamper before we climbed into the shower together. We started washing but I soon found myself on my knees, her silky pubic hair caressing my face, my tongue swabbing through her tangy pussy.

I made my sister-mistress cum so hard.

She drowned me in her pussy juices while the hot water rained on my back. It made me feel so wanton. She made so many passionate noises, grinding her bush across my face and tickling me with her curls.

It was so naughty.

We used up all the hot water and were forced out as the water turned cold. We darted back to our bedroom naked and laughing, our mother moving through the house below. It made me feel so wicked that we were having so much naughty fun without her realizing it. She had no idea her two daughters were a pair of kinky sluts into incest.

Sluts who were setting her up to be seduced.

Dressed, we headed downstairs for breakfast. Mother had it all ready. We sat around the table, chopsticks in hand, eating rice drenched in egg. I kept glancing at our mother, wondering what pair of panties she wore right now.

I would love to lick them. I wanted to feel them still warm from her pussy. It made my cunt so wet. I shuddered, my heart hammering. My cheeks felt so warm as I kept glancing at her, picturing her naked. She was such a beautiful woman, elegant and refined.

She would look amazing naked.

“What, Minako-chan?” she asked, giving me a look.

“N-nothing,” I said.

“You keep staring at okaasan like she has something on her face,” Kimiko said.

“Is there something on my face?” Mother asked. She grabbed her napkin and wiped at her face.

“No, no, Minako was just ... was just wondering if we could find natto in America.” I missed having fermented soybeans for breakfast.

“Well, I am going shopping,” Mother said. “There is an Asian store that imports Japanese and Korean items I’m trying out.”

“Minako would love to go with you,” my sister purred, giving me a wicked look. “Right, onee-chan?”

There was something in her eyes, an implicit command. “Y-yes, Minako would, okaasan.”

“That’s wonderful,” Mother said. “I would love to have the company. And what would you be up to, Kimiko-chan, all alone?”

My twin sister gave an innocent looking grin. “Just lounging around.”

She was up to something. What? It wasn’t my place to ask. She gave me an order. She wanted me out of the house for some reason. So I just kept eating breakfast while my thoughts whirled with what naughty ideas she had.

Did this have anything to do with this evening?

“Should I make something to bring over to your new friends’ house for dinner tonight?” Mother asked. “I could buy the ingredients while I’m out.”

“I’m not sure,” Kimiko said. “I don’t think so. Zoey’s mom was so excited. I think she’ll have everything we need to have an amazing evening.”

“Are you certain? I would hate to be rude.”

“Just showing up should be enough,” Kimiko said, giving me a sly look. She had a grin on her lips. “I think we’ll find this such an eye-opening evening.”

“I am so glad you girls are making friends. This Zoey and Lee sound like great girls.”

I almost choked on my breakfast.

“Are you all right, dear?” Mom asked me.

I nodded my head. Lee had seduced us into incest, giving my sister that last push she needed into acting out on her depraved fantasies. And Zoey ... she was mentoring my sister over the internet for months, guiding her towards tonight.

Nice wasn’t the right word to describe any of Clint’s sisters. Naughty was.

I helped Mother with the dishes, getting used to the butt plug buried into my asshole. It teased me as I moved through the kitchen putting away dishes. It made even something so mundane feel so naughty. Especially with my sexy mother was nearby.

It was like breathing in her pussy musk off her panties had opened my eyes to just how sexy our mother was. She was a taller woman than me, her face round, her lips delicate. She had larger breasts. They looked so round through her shirt. I wanted to squeeze them. Her jeans, while not tight, showed she had lithe legs and a butt that I wanted to play with.

I soaked my poor panties as I kept drooling over her. I couldn’t wait for tonight.

“Well, shall we, Minako-chan?” she asked once we were done.

I nodded my head, afraid of speaking and betraying the lust I felt. My cheeks were both so warm, my nipples so hard against my top. I fetched my purse, gave Kimiko a goodbye kiss, and then met our mother at the front door.

We had a car here in America. Something we never had in Japan. But it was necessary. Everyone had cars here. There wasn’t the network of efficient trains and subways to get us around. Mother drove slowly, both her hands gripping the wheel as we drove on the wrong side of the road.

My phone chirped when we reached the grocery store. I pulled it out and saw a text from Kimiko. I opened it up to find a picture of my sister unbuttoning her blouse, a sultry look on her face. It was taken from her phone but...

But it was clear that someone else had taken the photo. Who? Lee? Zoey?

My cheeks warmed as another text appeared, this time with her topless. She didn’t have a bra on, like me. She had one hand cupping her small breast, a sultry smile on her lips. Her left hand rubbed at her stomach.

“Shall we?” Mother asked.

I let out a squeak of shock, clutching my phone to my chest. My cheeks burned. Why was my sister sending me such naughty photos? My phone chirped again, vibrating against my small breasts, tingling my right nipple.

“What is your sister sending you that made you blush like that?” Mother asked me.

“N-nothing,” I said. “She’s just being weird. You know how she is?”

My phone buzzed again.

Mother gave me a speculative look. My heart pounded. If she saw the photos ... This was too much. I wanted to melt away. I could see it in mother’s eyes. She wanted to see what my sister was sending me.

“Do I need to talk to her about what’s proper?” Mother asked.

“No, no, Minako is just over-reacting,” I said. My phone chirped again.

“Okay,” she said slowly. Then she opened the car door.

I bolted out of the car. My body shivered. My pussy was so wet. My sister had sent me three more pictures. I wanted to look at them. But mother was right there. My pussy itched. I had to know. I had to look at it. I had to find out what my sister texted me.

I let Mother pull ahead of me on the way to the H Mart, a large store with Korean script included on its sign. I pulled my phone from my chest, unlocked the screen, and ... I wanted to melt away. The pictures were so naughty. The next one was her down to her panties, her left hand rubbing at her crotch, her right pinching her nipple. She stared at the camera with such smoldering eyes.

It was like she was staring at me across the miles separating me. She wanted me to see this. To see her.

The next picture had her ripping her crotch to the side. Her black bush spilled out around her soft-blue panties. Her fingers were sliding through her bush, caressing herself. My pussy clenched, my asshole squeezing down on the butt plug. It was so hot. I wanted to eat that pussy again.

The final pic she sent me was her prying apart her labia. Her pink depths glistened with her excitement. Her fingers stroked up and down her slit. She humped up into the air. Her breasts looking like they were bouncing, her mouth open.

“Minako-chan,” Mother called, stop dawdling on your phone.

“Sorry, okaasan!” I gasped and hurried forward.

My phone chirped again.

I shivered, wanting to look. I squeezed my phone tight as I rushed after her. I darted into the store and glanced at my phone ... I wanted to moan. Kimiko was on her hands and knees now, her rump facing the camera, her fingers buried into her pussy. A second pic arrived. She was now fingering her asshole, too, her face twisted in passion as she looked over her shoulder.

Who was taking these pictures of her?

I trembled as we moved through the aisles. I wanted more pictures. I wanted to see what my sister would do next. I wanted to get home and find out who was filming her. I wanted to lick her pussy and make her cum.

No more came.

I ached to masturbate. My poor panties were soaked as I moved through the store with mother, drifting after her in a haze of lust. I shivered, wanting this to get over as fast as possible. I wanted to get home. I burned to be with my twin sister.

“Are you okay, Minako-chan?” asked my mother.

“Minako is fine,” I said, my voice so throaty.

“Is it those texts from your sister?” she asked.
