Jake and Adam are 9 year old boys, and they had a privilege to be invited by a girl of the same age, named Olivia for a sleepover. All three friends known each other through the same grades at school, and they all get along through recess and other things, which recently, they went on a day out in cinema, which they enjoyed it so much.
Of course, the three kids gets to spend a lot more time at Olivia's house for a weekend sleepover, which they looked forward to it the most, especially when the girl is excited to host the two boys, while spending time just for themselves. Even both Jake and Adam are happy to be here, which they get a chance to speak to Olivia when they're in the living room, having just arrived a few moments ago.
"Oh, this is gonna be the best weekend ever, now that it's just the three of us together." Jake says, knowing he wouldn't have to bother with his parents at the time being.
"Yeah, it feels great to come over to your house for a sleepover, Olivia. I'm looking forward to it too." Adam replied further, which both of them sat on the couch.
"Aww, thank you for coming to my sleepover, you two!" Olivia smiled heavily from the boys' compliment. "I can't wait to have all the fun we can do, which makes me wanna do this surprise I"m about to bring you just now."
With that, Olivia would head off to her bedroom, leaving the boys be for the time being, as she's about to collect three presents she prepared for a huge surprise for them to choose one of them. It wouldn't matter in either way, because all these presents they choose, leads to the same outcome she wanted to try it on herself.
Y'see, it was during the cinema when Olivia took notice of Jake and Adam were staring at a woman, who instantly grew bigger and fatter so much, it made them glare into the screen with their blushed looks on their faces. The girl found it surprised by the boy's reaction to a huge, obese woman so much, it made herself wonder maybe she would impress them by getting bigger and fatter of her own? That was the reason why she invited them along, so she wanted to make a surprise, and thus, she cannot wait to feel how huge she can get, hoping to get a bottom-heavy shaped body, the same that a woman in the movie had been.
Of course, there was no time to waste, as it wouldn't take long until Olivia carries three presents to the living room, and sets up by placing on the table in front of the boys, which she smiled and offers them with her hands on her skinny hips.
"Okay, here's a game for you, choose one of them, and open up to see what it is." Olivia offered.
Both Jake and Adam nodded, and soon had to figure things out, which of these presents which had numbers 1, 2, and 3 in them. What they don't know is number 1 is a wishing ring that grants wishes by a user slipping the ring to its finger, number 2 is a ray gun Olivia was able to get it from his uncle from a basement lab, and number 3 is a bottle of potion she bought from a magic shop recently.
The boys had to figure things out, while Olivia looked on excited to that fact she gets to grow bigger, no matter what. It would take some consultation before both agreed that they choose which present to open?
