That smirk on the look of Madison's face indicates that Jason is caught blushing a moment when he stared right at the TV of a obese woman squashing a little man, and there was nothing he can hide, but admits he kinda enjoyed watching it, which made his girlfriend a lot jealous for this. When she said that can distract her boyfriend even further, Madison would show something that was hidden behind her back, and unveiled what looks like a toy gun of some sorts. It sort of have different bright colours like water guns kids would get from the toy shop, and it made Jason somewhat curious but confused all the more, when he tried to ask further.
"Umm... does it look like a water gun we played this a lot, Madison? I mean, h-how would that make me distracted when I just admitted to like this fat woman a lot?" Jason wondered in a bit of a puzzled expression.
"Silly me, Jason! You think that would help you get distracted by squirting you with this?" Madison laughed at that thought, before she starts to make a grin look again. "But that's not what it is! This is the device my Daddy made, and he gave it to me as my birthday present."
Of course it was true that Madison received it just a month or so ago, and the story goes that her Dad is the scientist who made lots of gadgets as a hobby, but also as a project for different companies. He made this a ray device, that actually is used as a size ray, and what it does is the device will trigger on something or someone, either making it fatter, or even changing heights by growth or shrink. Madison already tested this device already just to give that a try, but it looks like this will be the first attempt she's gonna be using the device on herself, and her smiling tone knew it was the only choice she wanted to make Jason admire her a lot more, so her jealously of seeing a obese woman tells a story.
"Oh, umm... I didn't know that was the device your Dad made it for you. B-But can you tell me what can be used for?" Jason asked, which he starts to look a bit nervous in some ways.
"Oh good question, Jason!" Madison giggled as if her boyfriend had asked a very good, and curious question." Y'know, I could tell you what it can do, but it'll be a lot better if..."
