"Want us to help?"

Never in the past 9 months would you ever expect your two older step-sisters; Jimin and Minjeong who are Alphas, to ever say those words when you're in heat, all helpless in bed with trembling legs under the duvet covers. Was your scent that strong to the point where they could smell it from outside your room? What if they got a rut because of you? The guilt ate you up like a virus, and the hot tingling feeling inside of every part of your body wasn't helping you one bit.

All of this started 9 months ago, your mother remarried to a new wealthy man, wanting a new life from the troubles in her past marriage, but with the new man; there was his two daughters. The taller one that seemed to be older than you, her black jet hair was down on her shoulders to her back, her cold eyes softening while looking at you with a subtle surprised expression. While the shorter one with shoulder length hair checked you out, eyes going up and down with an amused expression. You felt slightly embarrassed, they were rich and hot!? Fuck you felt like you didn't belong, especially since the two sisters were clearly full blooded alphas, you could smell their strong furious scent a mile away. They didn't want to come and have a stupid family meeting but their thoughts immediately changed as they saw you for the first time. The newly married couple smiled in excitement, wanting for their daughters to get along like they always hoped. Your step-father cleared his throat and introduced his daughters to you.

"Y/n, these are my daughters, Jimin and Minjeong. They're a little older than you but I'm sure you three will get along!" He said to you with a large smile, tone evidently happy and excited. You simply nodded while looking down, avoiding eye contact as you were still feeling anxious from the intense stares by your step sisters. The tall man noticed and coughed, changing his tone. "Girls, this is Y/n, I'm hoping for you oldest to treat her with hospitality and kindness." His face looking serious, like hinting that they shouldn't mess with his 'warning' like statement. They hummed in unison, their eyes not leaving you. Your mom just bowed at the two young girls and tapped the mans shoulders, signaling for him and her to leave and let you three get to know each other more freely. So with that, the two left the large living room, the thick tension deafening your ears.

"Well... hello then step sister. My name is Minjeong, as my father said but you can call me Winter!" She introduced herself with a big smile, her hands on your shoulders for support. Surprise, you nodded flustered from how close she was from you face. 'So if she's Minjeong, the taller girl behind her must be Jimin' you thought to yourself while looking at the feline girl, noticing her eyebrows slightly furrowing at her sister. She came closer to the both of you and placed her hand on Minjeongs shoulder while side eyeing her coldly.

"And that makes me Jimin, you can call me Karina" Her voice deep and shallow, comparing the two, you could already tell who was older from their opposite demeanors. But you kept your mouth shut, assuming something can be deadly. Minjeong scoffed at her and pulled you closer, intertwining her arms around your neck. "How cold rina! Didn't you hear what Dad said? He said treat her with hospitality and kindness!" You wanted to die right then and there, you were sure the blush on your face was visible, almost making you look like a tomato and Minjeongs scent was so strong it started to make your mind go blank. You looked at Jimin, her face filled with annoyance, she noticed your stare and looked back at you, her expression contorting and going soft.

With a sigh she apologized and held your hand, slightly pulling you away from Minjeong. "Sorry for my rudeness, this is just how I greet people. I hope you didn't take it the wrong way." This time, Minjeong was the one who's pissed, she rolled her eyes and gently pulled you back. "Hm, I didn't know you were capable of apologies, is our new little sister an exception or do you just not want to look bad?" She asked with a sly grin, intentions clear that she wants to make Jimin look like a horrible person. You heard a low growl from the taller girl, coming closer to Minjeong with a sharp glare.

With that the competition of winning you over started the day they saw you. From the small things of quick physical touch, flirtatious remarks trying to seduce you, and strong stares when you're wearing something that's semi revealing or just hugging your curves. For them, your curves were perfect, how could they not stare? And of course, some days your two older step-sisters would race each other on asking you if they could sleep in your room, for some stupid reasons and which would lead to them glaring at each other and basically throwing insults until you tell them that they both can sleep with you for the night. The only rule was no snoring and funny business while you were asleep, you cherished your rest and you don't like getting waked up in the middle of the night. This was their chance to snuggle on to you and smell your precious scent, stating that they feel cold even though the duvet covers are warm and thick protecting them to any freezing temperatures.

You just let them do whatever they want with you, you can't just forget that they're still older than you and you still want to please them. As time went on Jimin decided to cut her hair to a short wolf cut, you thought that she was just feeling bored of her long hair but the truth is she over heard you in your room talking to your friends, stating that you find short hair on girls are attractive. She's that down bad for you. While Minjeong decided to grow her hair out, wanting for you to braid your hair into each others since you mother said that you loved doing that in the past. If simps were people, these two were its embodiment.

Now back to the present where you are currently going insane, not knowing what to do while your mind was spinning and going in and out of reality. Warm tears started to form in your eyes as you felt pressure, you loved them but you were just too scared! Whimpers were heard outside the room, making the two older girls worry, they agreed and decided to finally help you and maybe confess their love to you. As if it wasn't already obvious.

"Y/n... We're coming in, we don't want you to keep hurting." Jimin said as she unlocked the door, a gust of pheromones hitting them making their troubles in their boxers get worse. You lie on your bed trembling while clutching on to the fabrics if the sheets, trying to hold on to something.

"aw poor baby" Minjeong cooed, sitting on the edge of the bed pulling your body up gently wanting to kiss you, she held back, feeling scared that you'll reject it. Your tears rolled down your cheeks, feeling so vulnerable and guilty, you hated stealing their attention, you never felt worthy of their worry. Jimin went behind you and hugged you waist, going down on the crook of your neck and inhaled aggressively, hands trying not to give in to the temptation of touching and embracing your beautiful body.

"Baby... You shouldn't be so shy about these types of things. Please let us help you" She whispered all so softly to your sensitive ears, your pussy clenched in nothing as her deep voice made you even more needy. Whining as the tears kept rolling down your soft cheeks, Minjeong immediately kissed them dry as her knee got in between your shaking legs, making you feel some friction. You moaned out so lewdly, they both cursed under their breath with their cocks wanting to get inside of you and just fuck you until they're dry. "Unnie please... mhm" Without even realizing it, you started to spread your legs for Minjeong, feeling so hopelessly weak with your heart and body basically screaming for the touch of your older sisters. Minjeong and Jimins head perked up with excitement of you finally opening up, Jimins hands slowly roamed around your body while trying to rub her rock hard cock on your back hoping to get some tension. She cupped you beautiful breast with her other hand on your wet pussy, fingers gently circling on your clit. Fuck she couldn't wait anymore, she wanted to feel you and hear you scream her name.

Minjeong kissed your cheeks and slowly went down to your neck, feeling so happy that she can touch you like she have always wanted! "Oh god... I've wanted to kiss you and cherish you my princess, let us help you okay?" You moaned and shook your head in agreement, the two older girls started to undress you, night gown getting thrown out to the floor, you weren't wearing a bra and so they got to kiss your wonderful breasts with full passion like they've always wanted. They were basically eating every part of your body!! Being so excited and sometimes rough with you, they needed you so bad.

You completely gave into Jimins hold and pulled Minjeong closer to you, their warmth wrapping around your body. "Please touch me unnie, I need you both" A switch flicked in their head, with those simple words, they immediately went into breeding mode. Jimin nipped on your neck while roughly kneading your breasts with urgency, like this was the last time she'd be able to feel you. But you won't let that happen to your precious unnies. "Hm... You smell so good baby... You always do" Jimin complimented, moaning at her praise you called out to her, meeting her sharp gaze in a trance and kisses her passionately, placing your hand on the back of her neck. Minjeong however focused on your wet pussy, spreading your legs wider and going down on your throbbing cunt, she inhaled your addicting scent making you moan loud in Jimins mouth. "So fucking good fuck..." Minjeong growled, impatiently taking your panties off and ate your slippery cunt like there was no tomorrow. With your two unnies giving your sensitive body attention while the sun was setting, it was magical setting. Jimin kept praising you, whispering how good you were taking Minjeong, how cute you were when you were getting pleasured, and asking you questions that will lead to you answering in a soft whine, all while her finger tips wers drawing on your smooth stomach and other hand still on your soft breasts.

"My baby sister, do you like getting fucked like this? Do you want Rina-unnies cock?" She cooed, her mischievous smirk showed how much she enjoyed watching you getting fucked. Your mouth trembled, this was all so new to you, you'd just normally take pills to get through your heat but your mom forgot to buy you new ones for this month and so you only got informed during your heat. "Y-yes...yes I want u-unnies co- A-ah!" You tried to answer but failed due to Minjeongs wonderful tongue entering inside your tight hole, her eyes fixated on you. Your taste was making her go wild, you were far too much addicting! With the overwhelming pleasure coming to you, your legs tighten around Minjeongs head hoping to get some kind of support. But with the puppy like girls needs in tasting all of you and making you cum for her hard, she placed her hands on your inner thighs and pushed them on the bed leaving her more space for your sensitive pussy. She thrusted her tongue in and out of you while Jimin circled her fingers on your clit making you jolt.

"Unnie!- ah please... I'm close!" You screamed as your stomach started to bubble up in pleasure, you arched your back getting ready to cum, Jimin made you face her and roughly kiss you, moaning into her mouth while her tongue fought with yours. Minjeong was determined to make you cum, she went faster, and so did Jimin. Finally having the chance to release, you came hard with strings of moans and whines following, body shaking with your hips bucking onto winters mouth. Minjeong sat up kissed you deeply, passion in her tongue to make you taste yourself "Good job baby, mind to have one more, just for me?" Jimin kissed your ears and waited for your answer with loving eyes. You can't help but submit to them, your pussy was clenching on nothing and the need of getting filled up by your step-sisters just fueled the fire inside of you.

"Y-yes unnie" You whispered, their cocks were suffocating in their pants. Seeing and hearing you break from such orgasm left their member impatient. Switching their positions, Jimin positioned herself in between your legs and brought her huge cock out, smirking at the cute sight of you with tears and a hint of blush on your beautiful face. Minjeong made you go on all fours, facing her with her cock leaking with pre cum inches close to your face. You basically drooled at the wonderful sight, panting, you sticked your tongue out wanting to taste Minjeongs large dick. She chuckled with a pleased smile,

"Cutie baby, are you excited? You don't know how long we've waited for this moment!" Minjeong said, bawling your hair up and slowly inching you forward to her cock, you licked her cute tip, moaning at her taste. While Jimin placed her hand on your back as the other to your hip, getting ready to ram into you, "Hm... We ached for you Y/n, days on days fucking ourselves with the thought of you being all ours" Jimin entered your dripping wet cunt, slowly stretching you out. Her cock felt so good in you! You could basically feel her veins throbbing in your pussy. She thrusted slow but so hard, emphasizing on the skin on skin lewd sound with your gagged moan as Minjeong rammed her cock into the back of your throat. The two older sisters were too impatient to feel you!

With their incredible rhythm, the two of them fucked both of your holes while moaning and cursing, as their wish finally came true, Jimin went closer to your back and kissed the back of your neck, trailing up to your sensitive ear, "S-so fucking good baby... Fuck I want to impregnate you so bad..." The older girl growled while fastening her thrusting pace, your g-spot getting abused hard while Minjeong is basically using you as a flesh light not letting you breath properly. "Hm... Our baby sister is so cute taking the both of us so good, I think she deserves our w-wonderful seed in her holes right Jiminnie?" Minjeong stuttered with the feeling of your mouth was making her brain go insane, coming close to her release. Jimin chuckled as she gripped your hips harder, sitting up and fucking you with hard and fast thrusts making you choke with your saliva drooling on the sides of your mouth. "Fuck... Fuck.. fuck!!" Jimin grunted as she was also close, determined to fill you up with her warm and thick cum. While Minjeongs hips started to quicken her pace as she closed her eyes, throwing her head back while moaning your name over and over again.

Tears fell on your soft and puffy cheeks, you were so close, you wanted the feeling of your step sisters cum in you over and over again! But the feeling was all too much for the three of you, Jimin growled and finally came in your pussy as Minjeong fed her cum to you and pulled out, her semen going directly on your face and on to your breasts. The sight of you were too much! They couldn't get enough of you, immediately after that euphoric sex they wen on with different positions with you, making you wonder how much of a high sex drive and stamina they have!

As Minjeong marked your smooth neck, she growled as she was finally feeling your wonderful tight pussy. Jimin making out with you while you gave her a handjob, running out of breath you pulled away. She can't help but blush at your cute face, doe eyes glistening with tears with your rosey lips slightly apart, both of your tits making contact as Minjeong was fucking you from behind.

"U-unnie I'm close!" You screamed, the familiar feeling in your stomach forming, Minjeongs thrusts changed as her pace was felt with urgency to make you come. "Good girl, cum baby. Make us proud" The raven girl said as she kissed your nose, with one last thrust you and Minjeong shivered in pleasure, your juices squirted as she completely came inside you, while you felt warm cum running down on your hand, Jimin came as well, with soft moans and trembling hip making you stop from stroking her thick cock, Minjeong is still in you, being a plug for her and Jimins cum inside of your cunt. Somehow it made you feel a sense of comfort.

Jimin showered you with kisses, praising you while Minjeong licked your ear and whispered thank you's for making her cum so good. You felt warm with their embrace! Happy tears forming in your eyes, you tried to hide them by hiding in the crook of Jimins neck but the two of them immediately notices and asks what's the matter.

"Were we too rough baby?"

"Are your hurting? Tell us my love"

Their concern made you feel so loved, shaking your head, you both smiled at them and stopped hiding,

"I felt nothing but happiness and pleasure, thank you for helping me unnies, I love you so much" You confessed with the tears flowing down, their eyes widened as they smiled so wide, they've been waiting for those words for months!!

"We love you too Y/n" They both said in unison kissing your cheeks and marking your nape. With your two older step sisters comfort you felt happy and safe, hoping for the three of you to make more memories together <3
