Kim

-Booooooooringggg.- You groan, lazily tossing a beach volleyball up and down as you lie sprawled on the bed. Kim's knowing smirk when Tom finally said her name... it’s an image that will stick with you far too long.

"Why does she have to be so difficult? I want to fuck her, she wants to fuck me, and we both want to fuck Tom. Can't we just make this simple?".

-Tina, dear, don't be dramatic.- Your mom chides casually from the couch, flipping the page of a crossword puzzle. She seems entirely calm, unlike you, and beside her, Dad sits quietly, running a hand up and down her leg. Yeah, the whole 'zombie-dad' situation is one more thing you'll need to address someday.

-But Mom! It's so unfair! She already had sex with him twice! It's my turn now!-.

-Technically, sweetie, you did too.- She says it so calmly that you pause. Okay, technically, she's right, but those times don't feel like they count, both were back-to-back on Sunday morning.

Mom moves on to the next puzzle in her magazine: -So, was that why you were outside Tom's room yesterday? To get laid again?-.

You blink, caught off guard. In a split second, the doubts and fears you’d tried to bury come rushing back, mixed with the guilt of almost having taken that decision without involving Mom and Kim earlier.

-Sorry Tina, I shouldn't have asked.- Mom apologizes, noticing your reaction.

-It's fine... I was just... confused.-.

-Oh, honey, I know. Truly, I do. I'm confused too. Probably more often than you realize.-.

You raise an eyebrow, scrutinizing her.

-I'm serious.- She continues, her tone softer: -I know that it seems like I'm always calm and collected, but... Tina, I'm our mother. Our mother. You know what I always dreamed of doing with her... and now I am her. And I also have her memories, her personality, and I see myself from the outside and I think... wow. Just, wow.-.

You understand exactly what she means, and somehow, knowing that she feels this way too makes you feel a bit lighter.

-Yeah. Wow.- You comment, looking back up at the ceiling. Then her voice calls you again, low and playful.

-Tina, you know, maybe we don't have to sit around moping just because your brother isn’t here. Maybe we can turn this into an opportunity. What do you say?-.

You glance over, catching the way her fingers trace along her bikini top. Only, you realize with a grin, that’s not a swimsuit.

A broad grin crosses your face. Those things she always wanted to do to Mom... well, you wanted that too, didn't you?

---

You're quite sure you did something wrong. The fact is, you don't know what. At first, everything was going... well, you wouldn't say alright, but at least as you could expect: whatever came to you when you chose Kim, clearly it made all happy and giddy for the rest of the lunch and until the two of you departed from the hotel room, leaving behind your other sister in a heartbroken state.

You ended up saddled with her shopping spree. Shoes, perfumes, bags—you were balancing an entire stack of bags by the time you try to get her attention: you barely had the vision to walk without worrying about stumbling into anyone, but it wasn't easy to keep her pace.

-Hey, uh, sis? How many more stops are we making?-.

-Mh? Oh, you said something? You're not here to chat, you’re here to carry bags.-.

You nearly lose your balance at her reply. You were starting to reconsider your previous choice, but it was too late by then.

-I mean, I thought that you wanted to... you know, that it was some excuse to be alone and... well, I mean, like, have sex, and stuff.- You admitted, keeping your voice down; though you weren't sure if it was your hope or your fear at that point.

Without even looking back, she chirped: -Why on earth would I want that? This is your punishment, remember.-.

-Y-Yeah, I know, it's just, you and Tina were arguing about being my girlfriend and so... since you love me I, I thought that...-.

Suddenly, Kim halts, struck silent. You blink, taken aback.

-Kim? Are you ok?-.

Without a word, she turns and strides away, bypassing the stores. You rush after her, confused and anxious. She's moving fast, and a few minutes later, to your utter surprise, you find yourself in front of the last place you would have anticipated: Sierra Vista's Hospital.

-Kim! What are you doing? Wait up!- Panic settles in as you rush to catch up, fearing that she may have felt sick. Kim glances at a hallway sign, then strides purposefully in the direction of the clinics, barely acknowledging the medical staff who give the two of you curious looks. Soon enough, you're in an empty waiting room, where she stops again.

-Wait here.- She instructed, setting her bags down on a chair. And so, here you are, sitting there anxiously for her return, having no idea what's coming next. The last thing you need now is a curious nurse stopping to question you with all these shopping bags in a hospital of all places. Luckily, this part of the hospital seems desert.

Just then, you catch a glimpse of the electric blue of a scrub out of the corner of your eye, and you hear steps coming in your direction. You look down, hoping, praying for whoever they are to just turn around and leave.

-Well? What are you doing still sitting?- Kim's voice surprises you. You look up and are flabbergasted by what you see.

-K-Kim! Why are you wearing that?-.

Your sister, in what you can only suppose is a stolen nurse uniform, puts her hands on her hips: -Stop making silly questions and follow me, brother. And don't forget my things.- she turns around and marches away, and you have **** but to hurriedly collect all the bags and follow her lead once again; and if possible, this time you were even more agitated.

-What are we doing, Kim?- You whisper while furiously glancing around: -We could get in deep trouble if they saw you like this!-.

Unsurprisingly, you get no answer, and she eventually opens the door to a medical office. It is a small room, with a desk, a cot, and not much more; the weirdest thing is a doctor's coat dropped on a chair. You put your load on the mat, not because you intend to rest there, but only to be able to face her more properly this time.

-Why are we here? What if the doctor comes back? Can you expl-

-Put those on.- She interrupts you, nodding toward the clothes on the chair. Your jaw nearly drops.

-Are you out of your mind? This is a terrible idea, Kim! We shouldn’t even be here, let alone dressed like this! We could get into serious trouble-

Without a word, Kim strides over to the door and, to your dismay, locks it, using a key that you have no idea where she found it.

-There. Now no one will interrupt.-.

-H-How do you-

-Don't make me repeat myself.- She turns to you, her gaze sharpening: -Get dressed, Tom. Now.-.

You try to slur something, to insist that all this is madness, that you don't mean to do it. But her eyes give you no truce, and you find yourself reluctantly complying, swapping out your clothes until you’re down to your boxers, feeling absurdly out of place.

-Kim...-.

You tighten your lips as she refuses to talk to you, and you ruefully dress with the doctor's attire. There's everything: coat, shirt, tie, even a stethoscope. It's simply impossible that any physician has left them here accidentally, but how your sister is doing all this, you have no idea.

When you're fully dressed, you try again to stand up against this delirium, but she suddenly hops onto the desk, hooking a finger around your tie and tugging you closer.

-Did you want to see me, doctor?- She purrs, brushing a strand of hair from her face with deliberate slowness, her tone dripping with lust.

You swallow hard, glancing anxiously at the door: -Kim, we have to stop...-.

-'Kim'?- She interrupts, a teasing lilt in her voice as her fingers graze along your coat's lapel: -Oh, we're on first-name terms now, doctor? Yet, you seem so tense. Maybe we should... get more comfortable, huh?-.

Oh God. You can't help it, she looks so hot. You summon every ounce of strength to suppress the instinct to kiss your sister right there and then.

-T-This is a bad idea...-.

-Oh, I agree, doctor. Locking ourselves in here, all alone, a big, powerful man like you and a humble nurse like me... this is quite inappropriate for you... very, very naughty...-.

She presses closer, her eyes locking onto yours with precision, assessing your every reaction. Her subtle smile widens as she notices the shift in your breathing. She tilts her head slightly, exposing the delicate curve of her neck. Every inch of her pressed against you makes it harder to think, harder to resist. You can't... you can't control it, and you find yourself pulling her in and sinking your lips on her dainty cervix.

Her soft sounds send shivers down your spine, your hands instinctively finding their way to her waist, responding to the gravity of her presence. Your thoughts race back to all those nights spent dreaming of her, and now she’s here, wanting you, needing you.

"She is so thin..." You think, your thumb softly pressing next to her throat: "She seems so delicate... so light...".

She crosses her arms and lifts away her shirt, revealing a cute small chest enclosed by a black bra. Your hands are trembling at the sole thought of touching it, while hers are quite more apt: one encircles your head, dragging you in a passionate kiss, while the other, you instinctively catch it as it deviously gropes your hardening penis.

Just then, you hear some noise from behind the door, probably someone passing by, but it gives you the moment of lucidity you were waiting for.

-No, no, it's too dangerous, w-we have to stop.- You whimper, instinctively pushing her away.

-Shh.- She whispers back, her finger against your lips, her tone both gentle but firm. The way her wide eyes gaze into yours... Kim, please have mercy on me.

-You are the doctor now. You give the orders. I'm just here to help you. To take care of you. Just tell me... tell me what you need.-.

-I... I need, I need...- You stammer, your mouth feeling dry as sand. You gasp as her treacherous fingers lightly squeeze your virility.

-Do you need... my lips on your cock... doctor?~-.

Oh God.

Mercy.

-Yes.- You sigh, desperately closing your eyes. There's no way out of this. You can't resist, you don't want to resist.

Kim goes down on her knees, nimbly unzipping your stolen slacks and taking out your dick. She wastes no more time and takes it inside her mouth, while she slips her other hand inside her trousers, proceeding to rub her own sex.

She pleases you for some minutes, the skilled combo of her tongue, cheeks, and palate make your mind losing its grip on reality. When she pulls away, your cock is hard like a stone and covered with saliva and precum.

"This is so wrong.".

-You have to fuck me, doctor.~- She chants, her hand still toying with your prick.

-I'm a bad nurse that needs to be disciplined.~~-.

A rasping breath escapes your lips as you give her space to stand up again and turn around. She sensually struts her hips and lowers her trousers, then does the same with that sexy daring thong that she had just revealed.

-Come on, doctor. My pussy is aching, I don't know what it is. I need you to examine it, deeply. Very deeply.-.

"Oh fuck, this is so sick.".

You plow her from behind, your lubricated cock sliding in and out of her glistening pussy like a breadstick in soft cheese. Here you are, fucking again your sister for the third time, and in an even more depraved situation than the previous two. But, God, it feels so good.

You rest your face on her shoulders, inhaling the aroma of her hair, the smell of her moans. You tighten your grip on her slender hip, while she starts reciprocating your thrusts by bucking her butt in time. She supports herself with one hand on the desk, while the other goes to grope her breast.

-I hope... you're taking... good swabs... doctor...- She blows, her voice whining with passion.

-Because... this isn't just a quick check-up...-.

---

The sounds of your lips meeting are only interrupted by the soft gasps that escape during brief moments of separation. You squeeze the hand that is cupping one of her boobs and whose back is scrubbing on your nipple, while the other one is currently busy whirling around her little clit like a lump of dough to be flattened.

Lying next to you, your mom presses herself tighter on your body, her fingers sensually tracing the skin of your back. Fuck, she's so warm, and so wet. She's horny, and it's all for you.

-Feel any better?- She whispers after another round of making out. You nod, your cheek brushing against the pillow, lost in the moment. Never in a million years you could have imagined having her face this close to yours, or that the excitement coursing through your body would have thrilled on your nipples and spread a soggy warmth on your crotch, rather than making your cock hard. Yet, after all, you don't have a cock anymore, but a tight little pussy that your mother spent the last five minutes passionately eating out.

-That's good. Oh, that's good~- She moans, and you can't tell if it's that or your digits working on her. You lift your hands to cradle her face, kissing her again, savoring the closeness. Her eyes big brown lock onto yours, never saturated with eroticism.

-I love you. As a daughter. As a sister. As a lover. You're everything to me, Tina.-.

Your nostrils catch fire at those words. Of course, of course, she feels the same things too. She's having her little sister's, now daughter's, visage brushing against hers, and all the things you've always wanted to do with Mom, you wanted to do them with Tina too.

-Thank you. Thank you, thank you!- You throw yourself into kissing her and at the same time turn her onto her back, covering her with your light weight. You would like to sink into her, you just wish that your bodies, now pressed together, could blend into a single entity, until the distinction between you and her is lost, only pleasure remaining.

"Maybe we could, huh." You amuse yourself for a moment. A rhythmic sound of rubbing flesh makes you peek at the sofa.

"Woah. Daddy is... packed. More than the old me, I guess.".

-Does it bother you, sweetie?- Your mother asks, her tone laced with concern. You offer a reassuring smile, accompanied by a soft kiss.

-Strangely, no. I mean, I never would have thought that with Dad...- A shiver of excitement runs through you, a mix of emotions bubbling to the surface.

-But now I want him too. I want it inside me like I want my old cock inside me. And I feel so guilty for making my sister say this that I want it even more! Oh, Mom, I'm so envious that you get to have him every night!-.

A pleaded grin spreads across Jessica Harris's face.

-Well, I'm sure that...- She stops as your father grunts, his shots dampening the floor of the room.

-...maybe next time.-.

---

-Ohh yes!- Your sister cries, her feet spasming in the air and on your skin, her excitement palpable as she watches down at your penis pumping in and out her vagina.

Gone are your clothes too, discarded on a chair. So much trouble to put them on, and you were so quick to take them out.

-Keep fucking me! Keep fucking my fucking cunt, doctor!-.

She's noisy, too noisy, the thought of someone overhearing sends your heart racing. You want to respond, to voice your own dread, but only grunts escape your lips.

What comes next, is a whirlwind of positions and moans, each shift more daring than the last. You sit on the chair, while your sister rides you with a fervor that leaves you breathless.

Your sister turns around as if she's heard something from behind the door; instead, she just closes her eyes and howls, as your hands mechanically lift her buttocks and then pin her down.

Next, she has you lie on the desk while she plants her feet next to your knees, straightening her legs and swinging her crotch in the air, while she bends her torso forward and, holding herself on your pelvis, sucks your dick from upside down.

Whatever the reason for her position, she manages to blow the soul out of your cock, the feeling of her throat engulfing you mixes with the tingle of her thick hair to your stomach and sends your senses haywire.

Unsatisfied, she switches position again, this time mounting you reverse cowgirl-like, something less eccentric, but far from being less pleasing.

The risk of discovery looms over you, constantly pulled away and resurfacing stronger than before, intensifying the thrill, and pushing you further into the depths of your desires.

When you are close to orgasm, you sit up and hug her tightly, you want to feel her very essence sticking to you, you want to hold her thin form as if she could slip away at any moment, and moreover, you want to feel her shaking when you'll shot your load up her thick urethra.

However, she has other plans, as she jumps on her feet and kneels down, holding your manhood and guiding you to stand up. She wants to end it like you started, her hand stroking your member while she looks up at you with a striking, disheveled face, only that now she's rubbing your head on her soft tits and-oh-ohh-OOOOHHH!!!

Your cock shoots every last drop out of your sperm, covering her bare chest and chin, as she maneuvers it at her will. Your legs shake, your very energies having been squeezed out with your seed, and you fall sitting on the desk, catching your breath.

-F-Fuck K-Kim that was a m-madness...-.

Your sister straightens up and searches through the drawers for some handkerchief, wiping out the mess on her body before answering you: -Come on now, get dressed.-. She pulls out her clothes from beneath the desk, leaving you wondering about the logistics of it all.

-Kim, how did you... how did you do... all of this?- You ask, your breath still ragged as you put your own clothes back on. She's faster than you and flushes her mane out of her top.

-Duh, I just asked. Now let's move, I still need to buy a new dress.- She unlocks the door and marches out, leaving you to hurriedly take all her other acquisitions (you're **** to leave the stolen clothes crumpled on the floor) and run after her, a mix of confusion and exhilaration surging through you. Once again, you're scared at the idea of some staff member asking you what are you doing here, and you breathe a sigh of relief when you exit the hospital.

-Kim, Kim wait a second please! You owe me an explanation, right? I think that-

She pauses, turning back to you with an exasperated look.

-See? That's the problem, little bro. When you're with me, you don't have to think. You're not the one making decisions, you're not the one judging what we should and shouldn't do, you're not the one who is owed anything to. I am.-.

-What?- You're honestly shocked by her, her egomaniacal haughtiness, and for the first time since everything changed between the two of you, you feel the spark of anger for that.

-Who gives you the right to treat me like this?- You challenge, feeling the tension rise.

-You did.- She shoots back smoothly, stepping closer, a determined look in her eyes that makes you jump and almost drop her bags.

-You chose me over Tina and Mom earlier. You followed me the whole time, even if you thought it was risky. You didn't even attempt to take the lead, when I put you in charge. And you chose me as your first bod...- She hesitates and clears her throat.

-You're choosing me even now, Tom. You can't remain without me. That's why I won't give you any explanation, and rather I'll tell you to follow me back to the stores, and you will do it. Because you're mine, and you can't change it.-.

With that, she turns and walks away, leaving you with a whirlpool of emotions boiling in your chest. Your digits clench the boxes you're holding, their pressure making the plastic squeak. How dare she... how can she speak like...

She's leaving rapidly, and you're tempted to throw all her stuff on the ground and walk back to the hotel, and to decide that from now on, you'll spend all your time with Tina and Mom alone, because they'll never treat you like this. But as you try to leave, you're rooted on the spot.

Those eyes she just made, were the same inside the office, and were the ones she mocked at you with three days ago, while you were shagging her. Your entire resolution trembles in front of those eyes.

She's about to turn the corner, not even caring to check if you're gone or not. She doesn't need to.

Without another thought, you follow her.
