She retrieves a shoebox from under her bed and stands back up. Stan notices that there is a little hole cut out on the lid and curiously looks at Mia. “One more surprise” she says and sits back next to her brother. “When I shrink you, would you stand over this box, and when you’re small enough, crawl into this hole willingly?” she asks while circling the opening with her finger. Stan looks at the hole, and estimates that he’ll need to be roughly one inch tall to crawl into it. “God, she’s going to make me that small right away” he shudders. “What’s in it?” he asks. “That’s for you to find out, but let’s just say, it will give you a hint of what is coming the next weeks” Mia replies. She seems really excited about it, and Stan himself is curious as well so he says “Sure, I’ll do it”. Obviously very happy, she hugs her brother. She brings her mouth close to his ear and holds it there. Stan feels her breathing, which he notices, is pretty rapid, and suddenly feels her lightly bite his earlobe muttering “I’ll make your fantasy come true, little brother” and backs away, leaving her brother extremely flushed and horny.
Mia looks at her watch and sees they have only five minutes before their mother comes home. Deciding that they should start, she looks at her brother and just to be sure, asks again if he’s ready. Taking a deep breath and smiling at his sister he stands up. “Ready” he says and starts to take off his clothes. Mia leans back to give her brother some space. They discussed this situation already, and Stan didn’t want to get lost in his clothes, as he wanted to see his sister grow to immense proportion all the way down. He didn’t think of it as a problem, thinking he’ll be naked throughout the whole holiday anyway. But now he is standing in her room, with only his boxer short on and suddenly feels uncomfortable. He decides there is no way back, taking a few steps forward and slowly turns around. He sees Mia with a grin lying on her elbows. He fears her comment, when she is shaking her head with a frown. But is a bit surprised when she only says “way to big”, leaving him a bit relieved, but causing his heart to beat faster, knowing this is it.
She gets up with the box in both hands and walks to her brother. Seeing her handle the box so easily, while in one minute he’ll not be able to move it an inch, scares him for a bit, but seeing the cut out excites him even more. Mia hands the box to her brother and Stan puts it between his feet. Standing back up, he looks at his sister for the last time and says “be gentle”. Mia holds her phone in front of her and smiles reassuringly, saying “sometimes” and winks. Stan wants to speak but stops when he feels a tingling sensation. Mia pressed start.
The first seconds nothing happened, he looks at his sister but she is still the same height. Just as he wants to say to his sister that she did something wrong he notices a change. Slow but steady he loses height and his heart begins to race. He looks down at his body, but doesn’t see that much effect until he looks at his sister again and is startled. He already is eyelevel with Mia, and he knows she sees it as well. She is looking at him astounded. Stan smiles nervously at his sister causing Mia to smirk and points a few times down while looking in his eyes saying “too big”. In the next five seconds he’s down to his sisters breasts. While his perspective hasn’t changed much, the knowledge he is shrinking and seeing them in front of him, turns him on. Stan’s member grows and he hears his sister giggle and saying from above “glad you like them”. He looks back up to his sister and to his surprise he already shrunk below her breasts. He sees her sister sticking out her tongue to tease him. Stan decides to keep looking at his sisters face to give him a perspective.
In the beginning her face was full of wonder, but it now changes into something else. Her gaze is full of hunger and Stan knows it is lust. He nervously decides to check how much he has shrunken and looks in front of him. He tilts his head down past her belly, and to his surprise he is already past her waistband and stares directly at his sisters crotch. He is mesmerised by it and can’t take his eyes off it. He keeps looking at it while he shrinks further down and the upper body of Mia comes back in sight. Suddenly, he sees his sisters hand coming down and stopping in front of her crotch. Stan still has to shrink quite a lot, but is already astounded by the size of her hand. She puts her finger between her legs and sensually glides it up. He looks up to his sister and sees her face all flushed, mouthing “amazing”.
Seeing his sister get off like that of seeing him shrink, almost brings Stan over the edge. Suddenly he feels the shoebox on his calves, forcing his legs apart, bringing his attention back to his shrinking. He have to move fast, otherwise he will end up next to the box. He quickly positions both his feet on the box, and stands on the edge near his sister. He looks back up and is completely taken away. Thinking Mia backed away a few steps, he realises that his perspective is really changing now, because Mia did no such thing. He is already below knee level, and in ten seconds will be one inch tall. Stan looks up in fear of experiencing his sister at her new size. Stretching way above his head, she looks as tall as a house to Stan. Throwing off his nervousness, he shouts to his sister to take a step closer. Mia looks at her brother dwindling to his final height, she laughs and knows he wants to experience her body from a closer perspective. She takes a step forward.
Before she complied, Stan shrank to ankle height. Every second he takes a step forward to the edge of the box because of his increasingly smaller size. He sees his sister taking a step forward. There is no way to describe to see a something of the height of an apartment building moving so graciously. The power it possesses is too much to process. Stan begins to tremble and when she stands still he is finally at an inch tall. He is completely overwhelmed and takes a few steps back, but falls on his butt. When he opens his eyes, he cannot believe it. His sisters seem to stretch for miles, she is so incredibly big. He always knew there would be no way to stop her, but now it really sinks in. There would absolutely nothing he could do, he is her toy, her property and her pleasure for the next weeks.
He slowly gets up and gets his bearings. He looks backwards and is amazed that the shoebox she just held in her hands, was now a basketball court to him. The amount of detail he sees is amazing, feeling like it’s a whole new world. He returns his attention back forward and takes a couple of steps to the edge. He peers over it and is immediately greeted by the last body part he hasn’t seen since he’s been shrunken. Looking below, he sees his sister feet, incredibly big. Mia sees her brother looking at them and wiggles her toes. Stan looks with an open mouth to the display before him. Toes as big as him, able to lift the immense weight above them. He quickly backs away, before Mia decides to use them on him. He looks back up and almost screams when he sees the immense figure of his sister coming down. Mia decided to kneel to get a better look at her brother. Her mouth is almost watering with anticipation, but decides to say nothing. Instead she just taps behind her brother at the hole.
Stan is mesmerised by his sisters crotch before him. She can just drop him in there, and no one would notice. Suddenly he hears a tap behind him and turns around. He sees an incredibly huge finger pointing at the hole. Knowing what she means, he walks to it. Her hand gets even bigger when he approaches, and he notices to his amusement that he can see much more detail on her skin. He reaches the hole and looks back up his sister. Again, he is completely taken back from her.. He looks up while pointing down and shouts “in here?”.
Seeing her little brother the size of a candy, walking across the shoebox, turns her on immensely. His cute little voice almost brings her over the edge. She just wants to pick up his little body and pop him right in her mouth, but they agreed to take things slow. So she simply nods and taps her finger again. Stan almost cannot believe the strength and pace of just one movement off her finger. He looks back up to his sister, seeing that she cannot contain playing with him much longer and decides to go in. He lets his lower body fall in the hole and holds on to the edge. Seeing the cardboard in front of him, stretching for several feet, and his sisters body like a distorted mountain behind it, puts a smile on his face. He ways goodbye with one hand and lets go. He drops for a second before he falls on something soft. It smells like cardboard inside and it’s completely black, except for the hole above him. He stares at it for a moment, letting it sink in. Just as everything else in this box, he just have to wait until Mia decides she is ready to use him.
“Awesome” he says, waiting for the inevitable.
