“Nick… Niiicky… Nick!” the insistent shouting of your name makes you snap out of Instagram Reel’s mind controlling brain rot, hours of mindless scrolling stopped only by your step-sis’ increasingly loud voice “Angie?” you stare up at her, half lazily and half surprised “Like, duh! Who else would it be silly!” she giggles with an added bounce to her step, a bounce that wobbles two melon sized breasts with little to no effort, their mass easily deforming the front of an ill-fitting top that can barely hold her boobs in place. A top you’ve seen her wear around the house a lot, just not with the huge tits that are taking up her chest, stretching it out way past the manufacturer’s intended size limit. Turning the piece from cute loungewear into a slutty top that displays some eye-catching cleavage as it hugs her surprisingly skinny waist like a second skin.

“My boyfriend’s coming in a few minutes and I need you to let him in while I pretty up, kay? Thankies~ Be back soon!” Angie happily skips off to her room with no need for your answer, leaving your mouth agape on the couch. Didn’t she just get out of a pretty toxic relationship? Since when does she speak like an airhead? She’s hated the blonde ditz stereotype since forever. And why are her boobs so huge? It’s not like you know her actual cup size to have a reference point in order to compare the honeydews hanging off her chest, that knowledge would be quite creepy to have, but you are damn sure that just yesterday they were not the size of her head and then some more!

You are still processing the mind-boggling encounter that transpired in your living room when a knock echoes through your front door, loud enough to demand your immediate attention “Coming!” you stand up to answer the door for, presumably, Angie’s boyfriend “Hey there cutie, I’m Tyler. Is Angela home?” your mouth opens to answer the - surprisingly attractive - young man standing at the doorway, but it can’t find the words immediately because who starts a conversation with another guy like that? “Uh yeah, come in, she’s readying up” regardless, it defaults to the expected answer, failing to register the added sway in your hips as you lead him to the couch.

“So… how long have you two been dating?” you ask in an attempt to loosen the suffocating ambience brewing in the living room. Mainly from the intense gaze that he’s laying on your body, making you squirm and shift uncomfortably in place “Like a day or two, she didn’t mention a sister. A cute one at that” what is he talking about? Can he not tell that you are a g- “I’m actually her step-sis…” you correct him, although with a frown, the words feel wrong, but you are not quite sure why “Really? I couldn’t tell. You two are so similar down to the hair, but I think your shade is prettier, don’t tell her that though” you can’t help but awkwardly chuckle through the blush slowly painting your cheeks, meekly brushing a strand of your blonde locks away from your face as you not so subtly take in good eyefuls of his body. Angie does not miss with her choice in men, every time you look at him, he is doing the same right back at you. Gliding his eyes over every curve of your body, it makes you self-conscious in ways you’ve never felt before, your tank top is suddenly too low, baring too much of your budding cleavage. Your thick thighs too prominent within the tight leggings you so comfortably lounge around in, even when you press them together to try and drown out the growing heat in your tummy ‘Come on Nic, it’s your sister’s boyfriend!’ the protest is laughable when faced with the ever-increasing needs of your developing womb, clearly instructing you to take what you want.

“Water… I… uhm, want some water?” you mumble, getting up on legs that feel and wobble like jelly. He tracks your every move from the cushion, lingering on each delicious jiggle of your ass, pressing the full weight of each cheek against the thin fabric of your leggings every time they bounce with the rhythm of your steps. Presenting their full round shape once you reach for a glass from the kitchen cabinets, strangling the fabric when you bend over to fill it with water and jiggling wildly when you jump back from the shock of having dropped the glass from your delicate shaky fingers “Shit” you let out a breathy whisper, fully conscious of how tantalizing your bubble butt must look as you lean forward to wipe at the messy puddle on the counter, gently pressing your modest tits into its surface not quite used to their presence on your torso “Damn girl! You might not have her tits, but you sure as hell can compensate!” Tyler’s whistle makes your cheeks burn with shame ‘It’s your sis’ boyfriend Nicole…’ shame dissolving into something else, something that’s making you hyper-aware of the bottoms hugging your ass, held perfectly around the massive globes that define your silhouette and that have so kindly enamored Tyler’s attention for you. Without further thinking, you begin swaying your hips slightly, exaggerating every little move as you wipe up the water, deliberately, sensually slapping your meaty globes against the back of your plump thighs.

“Aah~” your body freezes as a hand clamps down on your buns, grasping deeply into soft flesh it is incapable of holding on its own, the fingers yielding beneath its size even as they try to dig deeper “Don’t stop, you had a nice rhythm there” his groping hand sends sparks of heat through your whole being, sparks that are so, so wrong, but you don’t care anymore, not when he is so possessively claiming your ass just for his own hands “Angie is a klutz, she won’t - haa~- notice that we are gone if she miraculously does her make up in less than an hour” your voice comes in-between breathy, pleading gasps as you slowly grind against the bulge forming in his pants, rubbing it between your round behind with the eagerness of a bitch in heat “My bedroom? Now~?” he doesn’t answer, you are glad he doesn’t, instead he guides you onto the promised bed where he pulls you onto his lap, pressing his exposed meat into your leggings. You don’t hesitate, nearly ripping the things off to let him in “Oooh~” moaning like a slut as your walls eagerly clamp down around his cock, greedily sucking him in with each grind of your hips before you even start to properly work it “Fuck~” you giggle with his groans, bouncing your fat ass on his member, letting him feel the plumpness of your soft cheeks every time you fall back on his hips, taking him deeper into your body with every eager bounce. Angie may be a ditz, but she’ll definitely notice how much her boyfriend reeks of fresh sex, not like you care, she needs to learn and share with her big sister.

I didn't really know what to name this one, my brain refuses to make something interesting for a title, but that won't stop me from posting a completed story. New post from the suggestion box coming probably on Tuesday since I need to make a free story to upload on DeviantArt (ran out of early access backlogs to upload💀). Anyway, see ya on the next one : )
