You were absolutely confused. Who left these bracelets? How did they get in your room? Why would they leave a note telling you that these bracelets could make you much fatter? After adding up your friends' previous weights from memories, and then adding it with half of your mom's and sister's weights, you were led to the conclusion that the left bracelet would increase your weight by an entire ton. Your friends were all originally inspired to get fatter by you, so it felt wrong that you ended up being the thinnest by far. Although being so fat as to weigh an entire ton was daunting, and apparently that was only the effect of the weaker bracelet. But at the same time, it seemed fascinating. Your curiosity won in the end, convincing you to slip the left bracelet onto your already thick arm.
The metal bracelet you put on fittingly had the words "Big Girl" engraved on it. After reading the inscription, you suddenly felt your belly rumble before it began growing. Rolls upon rolls of fat flowed both outwards and downwards, sagging all the way down to the floor. Your breasts grew alongside your gut, but much less, just barely not being enough to burst out of the new bikini top you had put on just before, thankfully. Even if they had become too big, you wouldn't be able to fix it as your arms had become so thick that it would now be impossible to squeeze the bracelet past your fatty hand. Your legs had also thickened to an admirable degree, to the point where it would be impossible for them to ever not be in direct contact with each other. New chins made their home on your flabby neck. Your butt would now require four chairs in order to be properly supported. But your belly is what stole the show, being absolutely immense, sticking out about a meter in front of you, and was even larger in terms of width.
You were in amazement over how huge your body had gotten because of a simple bracelet. You wanted to see if you really weighed more than a ton, so you waddled over to the doorway to go to the bathroom, but you immediately realized two problems. One, you would most likely crush the scale under your newfound girth, and two, you were twice as wide as the doorway. There was no way you would be able to squeeze all of your mass through, which was a problem since your friends were waiting for you. However, there was one other way out; your bedroom has a rather large window facing the backyard. If you were to leap out of the window, all the way into the pool, that would make quite the entrance. You waddled over to the window and peeked down at your obese friends; it seems that they are waiting for you to come back before they they get in the pool, which was good. You struggled to lift your foot up to the window sill, and readied yourself to create a spectacle.
Your friends were chatting with each other when a large form fell into the pool, flinging the pool water into the air, before it all fell back down like rain. They all waddled over to the pool to see what the cause was, and looked down into the now emptied out pool, seeing your enormous new form.
