"Oooof, heads it is" your mom announced
You put your face in your palm as Melody led a celebration over her victory. Your mom handed Melody the shrinking device, which she quickly strapped onto her wrist and started messing with it's settings.
"You can't be serious..." You protest.
"You'll live Alex, it's just your little sister she's harmless, be grateful that you get to go on a trip at all" your mom preached at you, but you knew better.
"Yeah Alex" your sister smirked at you "be grateful you get to be shrunken by someone as harmless as me..." Your heart raced as Melody looked back at your mom "So when can I shrink him??"
"Whenever you're done packing, we leave tonight so get your bags together" Melody smirked at you and immediately ran to her room
You pulled your old suitcase from under your bed and began searching your wordrobe for some cloths to wear on your trip. You began lightening up about this situation. You got to go on a fantastic vacation, with your family, in a high demand tourist location complete with a five star hotel, a mall, beautiful beaches, restaurants, pools, the whole works. The only catch was needing to be shrunken by your little sister, who from apart from maybe teasing you will probably just throw you in her purse in a make-up container. The flight would be over before you knew it, and you'd get to enjoy paradise as the big brother. Hell maybe you can shrink her on the flight back and get some revenge. This has the potential to be amazing...
You finish packing and go on your phone for a bit while the rest of your family continued packing. It was about 3:00pm at this point, and you were leaving for the airport at 4:45pm meaning your sister only had a little under 2 hours to work out how to pack you in.
Just seconds later your sister called you to her room. You walk in to see her bag fully packed and zipped up. She's wearing dark blue leggings and a crop top, both complimenting the features which she clearly inherited from her mother. She had the watch on as well, smirking at you as you walked in, She pointed at her bed, signaling you to have a seat as she shut and locked the door behind her. This was normal, she had a nag for locking her door all the time.
"So bro, do you have any ideas on how we can do this without you being caught by security???"
You look at her puzzled, you began thinking and couldn't come to any conclusions... "I mean, you could always just put me in your purse? Or like your suitcase under some clothes?"
"I don't know bro, security is so strict these days, and if they find you who knows what will happen to you, or the rest of us... we really need to think outside the box" she explained.
"So then what did you have in mind, we only have and hour left-" you were cut off by a beam that struck you in the chest. You began shrinking rapidly as your sister approached your increasingly shrunken form on her bed. You looked up at her as she towered over you as you shrank smaller and smaller. Then the beam finally stopped. You gazed up at your sister, about 60x your size. She looked at least 400 feet tall, and to her, you looked no more significant than a praying mantis. The size of a bug to your little sister.
She smiled down at you, approaching her bed until her thighs were pushed against the bedsheet you stood on. You could no longer see her face from behind her bust, while in front of you was a wall of thighs and your sisters right cameltoe. She opened her mouth "I've got a few ideas little bro..." She reached down and grabbed you and pulled you up to her face. She dangled you in front of her eyes as she stared down your new size, all with a giant grin...
"You see big bro, security is going to turn my bag inside out if they even suspect I'm smuggling something, or in the case someone, to the island, so my bag and my pruse are just not safe enough options for you, I think we need to explore our other options..." she lowered you down to her waist, you got a full view of your little sisters body, coverd by skin tight leggings. With her other hand she stretched her side pocket open and dangled you above it. You looked down into the abyss of fabric...
"This could work big bro, wanna try it?" Before you could protest she let you drop straight down into the dark pocket and let it snap shut "Hmmm, I mean you are hidden but this isn't exactly the best compromise, like what if they check my pockets and find you or what if I forget about you and you're crushed by my giant phone??? We wouldn't want that..." She opened the pocket and lifted you out, you punched her thumb in protest but she didn't even notice. She lifted you back to her face and looked at you again...
"You know, there are other places that we can hide you, though I'll warn you... You're not gunna like them..." She giggled to herself before tossing you onto the bed. She once again towerd over you before she began speaking again. "We've been thinking about this all wrong really, we've been thinking of places security was less likely to check, and not places they CANT check" you didn't like the sound of that. Your sister gave you and evil grin as she began lifting her shirt. "See, now we're thinking outside the box Alex, I'm really glad we could put our heads together and figure this one about bro..." She removed her shirt completely, revealing her red lace bra, barely containing her massive tits. You couldn't believe what was happening, you didn't even think for a second before turning and running from your colossal sister.
She watched as you ran, before calmly reaching out and blocking your path with her palm. You looked back at her and protested "You've actually lost your mind if you think you're going to carry me below your clothes"
She ignored you "Remember like two weeks ago when you gave me that really bad wedgie at the dinner table while I was eating" she began pulling down her leggings, barely able to pull them over her massive ass cheeks. She revealed her red lace thong, matching her bra. It was a sexy set, that horrified you. Your sister was threatening you with exploration you'd never wanted to even consider.
She turned around showing you her massive ass and the red thing trapped inside her cheeks. "I was wearing these when you gave me that wedgie. Man it hurt, I could've killed you I swear to God" she hovered her ass directly above you "I think it'd be funny to give you a massive wedgie too, just not in the same way..." She moved her lace out of her ass and to the side, revealing your little sisters asshole, probably multiple times your size. Each cheek jiggled as she spoke, each the size of a two story building. She laughed at your expression, peering over her shoulder at you.
She spun around and revealed her front, only covered by her underwear. She traced her hand down her stomach and to her tight pussy, cover only by a thin layer of fabric. She lightly rubbed it, dampening her panties. "Or maybe you'd prefer a different hole?? Haha" she laughed at you, you fell backwards onto her bed spread, horrified of your giant sisters woman hood looming over you "What's wrong bro, afraid of a little pussy??? Hmmm???" she continued to rub herself "It's so tight, there'd be no chance airport security would be able to find you in my virgin pussy big bro. You'd be safe and sound tucked up inside me for the entire flight, just as long as you don't squirm around, then we'd have to worry about you being able to swim hahaha" she broke out laughing, then she stood up straight and reached behind her back.
She unhooked her bra and let it fall to the bed, nearly crushing you. You look up and see your sisters DD tits hanging from her chest. "I've seen you stare before bro... It's okay, you can look now, I won't tell" she curessed her boob, pressing one into the other, "I can always put you in my cleavage, or hell maybe even on my little nipple. It'd be fun to know you're hanging on for dear life while I'm just casually playing games on my phone during the flight, don't you agree bro??"
You began to yell "What the fuck is your problem?! Why would you ever think I'd be okay with something like this??? All those things would kill me, on top of the fact I have no interest in seeing my little sister this way..."
"First off bro, drop the 'little sister' crap, I'm much much bigger than you and second I know you'd be drooling all over yourself right now if it weren't for the fact that you don't wanna be domed by your own little sibling..."
It was true, you couldn't deny the fact that it was very hot, but it was your sister, I couldn't let it slide-
"Awww see, he even has a little bitty boner in her pocket how cute" you covered your dick as your sister stood straight up and looked at you, pretty much naked. "Well bro, now it's time to make a choice, how are we going to hide you away, what of the things I just showed you, sounds the safest... And you better choose quick or trust me, I'll choose for you..."
