Your intense curves start to shrink, and you’re soon imagining your sister strutting along the ocean like she’s the sluttiest bimbo ever. You know right away that you’re not imagining her, and feel cooling relief as your tattoos fade away. You feel your facial expression soften as the smell of the ocean fills your nostrils, and girly giggles fill your ears as you’re brought back into reality.

“Is it so crazy to wear matching bikinis?? I think it’s super hawt!!” You feel your mouth speak, unable to stop yourself as you giggle with your twin and her bestie.

“Heather thinks we should try to fool my boyfriend, he has no idea I have an exact twin!” Jessica laughs, her hands playing your breasts and ass as she implies you have no choice in the matter.

Next thing you know you’re helping Jessica hide, and trying to act like her when her boyfriend walks into the beach house. Chris was always a jerk, and you would constantly get into angry fights with him when you were a man. Now all you feel is shame, but that’s deep down inside. Externally you struggle to not speak like a bimbo, your voice and vocabulary too slutty for Chris not to say something.

“Like, you don’t recognize me, sexy?? What do you mean who am I?” You feel yourself giggle, your hands massaging Chris’s crotch as your mouth waters.

Heather is gone now, and Chris plays along with your ‘new’ bimbo personality. He has you sit in his lap, and teases you for over an hour with his erection pressed into your butt as you make out. You leave his pants damp when you finally stand up, your legs barely able to support your own weight as you help Chris out the door.

Then your pink phone rings, and you reach for it without a thought. Jessica giggles from the closet she’s hiding in, and decides to change you just a bit before you all go to the beach.

“Bigger boobs, flatter stomach, more makeup, dick sucking lips like a goddess, and of course a booty that no man could ignore!” Jessica laughs, finally emerging from her hiding spot with Heather as you stretch your bikini’s cups and waistband.

You can’t even look at her though, your eyes fixed to the phone as Jessica whispers something to Heather. A straw hat then lands on your head, and you feel a sudden craving to flirt with boys. The hat tingles your scalp, and you feel your brain chemistry warp to demand attention from boys. Just thinking about a boy acknowledging you sends a rush of euphoria to your mind, but you know there’s a lot more of that to come.

“Can we like, totally go to the beach already?? My pussy’s like- O shit, sorry I shouldn’t- O fuck…” You suddenly moan, an overwhelming desire to feel a man washes over you, “I’m like, totes going right now…”

You playfully pull on your bikini strap, blushing as your DD cup breasts jiggle and bounce. The girls follow you out the door, and it doesn’t take long for a guy to say something.

“I thought I was going to the beach, but after seeing you girls I feel like I’m in heaven!” The strapping young man jokes, his smile warming your heart and making your lips pout with intense arousal.

“O really, stud? You think you could like, handle all three of these pussies??” You ask, flexing your hips and showing off your flatness as the kid flirting with you stammers.

“I- my- umm…. Wait, I could- fuck, that’s hot…” He trails off, his board shorts tenting up as you all giggle and walk away.

You spend the rest of the day flirting with different guys, eventually finding one horny and confident enough to take you behind a guard tower. You passionately kiss the beautiful man, stroking his bulging muscles with your manicured fingers. He reaches into your panties and gently rubs your pulsating folds, parting your lips and slowly inserting a finger into your womanhood. You buck your hips in response, dripping through your panties as you ride the hunk’s curled finger.

Suddenly Jessica comes from behind and lifts you by your shoulder, pulling you away from your man as Heather whispers into his ear. You whimper as his finger slips out of your pussy, legs quivering as you beg to be filled again. You see a new fire ignite in the confused man’s eyes as Heather whispers, and when Jessica lets you go he grabs you violently.

Your body giggles as you’re turned around, and a strong hand on your back forces you to bend at the waist. You feel a splash of cum on your ankles as your panties are removed, a puddle forming between your legs as a draft hits on your exposed dripping pussy.

You know the thrust is coming when two strong hands pull your hips in, but nothing could prepare your mind for the sudden penetration and explosion of euphoria it induces. You squeal with pleasure as you’re pumped in and out, your voice getting hoarse as the pleasure rises up your throat. Soon you feel orgasmic bliss flow up your torso and down your chest, meeting and pooling up in your womanhood as you’re brought closer to climax.

That’s when the loudest snap you ever heard suddenly explodes, and you practically black out as the echoes ring in your head. You could tell you’re fully clothed before your vision comes back, and celebrate when you feel your manhood between your legs. You jump up exceidetly, still woozy as you open your eyes to see Heather and Jessica standing right next to you.

“Exciting, huh?” Your sister laughs, “I don’t think you’re learning any lesson, and I’m really disappointed. You’re gonna have to prove yourself…”

Heather pulls at your boobs, stretching them and forcing even more fat into your chest. She then grabs your hips and closes her eyes, making your thighs blow up as your waist cinches in. She then pulls at your hair, lengthening it as your face extends from a circle to an oval. Heather gives you a soft kiss which you lean into, and you feel your lips plump up as she palms your ass cheeks. You let out a surprised squeal, vibrating Heather’s mouth as your ass inflates.

She grinds her hips into your crotch, your manhood erecting as Heather’s purrs. Her pants are so tight you can feel her separated folds on the tip of your cock, but you don’t say a word as she molds your body into a busty goddess. Your curves become too wide for her arms to hold, so Heather takes the opportunity to let you check yourself out in the mirror.

“Be perfectly honest, what do you think?” Jessica laughs, the looming threat of being transformed permanently always present.

“This voice and accent are hawt, but it’s kind of annoying to speak so… softly? And these curves feel so weird, like they’re extensions not connected to my body…” You trail off in your nasally voice, forced to hold your back with your left hand to balance your ass and boobs as you pose in the mirror.

Heather just laughs and strokes your now soft manhood, quickly pressing her crotch back into yours when you get hard again. She rubs her pants against your panties till her folds open around your cock, and then licks your ear before whispering into it.

“If you cum in the next five minutes, it’ll be gone forever…” She whispers in your ear, breathing into it as you penetrate her through both your clothes.

“Fuck…” You trail off in a ditzy voice, looking down at a strained thong pressed between Heather's two pussy lips and her pants.

“I thought she has to be on the phone to be transformed??” Your sister suddenly interjects, “Why did we have to do that whole thing with the phone if you could just…”

“Well to change her mind I would need the phone, but just body changes I could do at any time.” Heather says matter of factly, trying to keep sounding sexy as she stares into your eyes.

“And this is necessary?” Jessica asks, wanting to know what Heather’s up to now.

“You’re killing time here, Jess. If your brother cums before the clock strikes seven, he’ll be your little ‘big’ sister forever!” Heather laughs as she grabs one of your g cup boobs, “But if you distract me the clock’ll strike seven, and we’ll never have another chance at this!”

“Why don’t you just make her super sensitive and horny?” Jessica asks, making Heather have to hold back an eye roll.

“Trust me, it’s gotta be like this. We’re in a very specific situation right now, and you’re really being distracting. I can’t be penetrated fully, no mind changes, female body with manhood… I can’t even get into more of it!” Heather exclaims, her face red as she tries her best to look sexy.

She’s able to easily hold you down, your body too weak to get away as she humps your throbbing manhood. Heather then has a lightbulb moment, and instructs your sister to tweak your nipples. It takes less than a minute of Jessica’s giggling and twisting, and Heather’s eyes glow bright red as you have the most intense male orgasm of your life.

You can’t tell if the cum pumped through your thong, but when Heather pulls away from you her pants are soaked. You look down to see flat panties, and defeatedly reach down to confirm your suspicions. That’s when Jessica calls your phone, and you have no choice but to answer.

“Half IQ, more girly, more slutty, forget your old life, and you’re Heather’s lesbian lover now!” Jessica laughs, warping your mind and making your eyes glaze over as all your past knowledge evaporates.

“I’m not lesbian, Jess! That was just the necessary process, you can’t change me!” Heather protests, her beautiful body moving so… Beautifully…

You giggle as you struggle to complete a sentence internally, and give your sister a look at your new bikini as your delicate fingers run through your hair.

“Like, come here, babe!” You giggle as you hang up, trying to grab Heather as she ducks away.

You frown flirtatiously and chase after her, almost feeling like that skunk from the cartoon as Heather runs. Jessica just laughs, satisfied with her prank on her friend and happy to know that she wouldn’t be snooped on by her gross older brother ever again.
