Waterlogged Rachel

Rachel was watching TV on the couch when a Coca-Cola commercial came on. Much like 9/10 of Earth's population it made her thirsty. She probably already was very thirsty but didn't realize it. She went into the kitchen to get herself a drink when she noticed a six pack of 1,5 liter water bottles. Rachel had always secretly loved having a big, round belly so this was very tempting. She, after hesitating for a while, picked it up and took it to the living room. She got the incredibly hard to open plastic off and opened the first bottle. A voice deep within her was telling her to drink everything. That was, apparently the most dominant voice and she started chugging. She made occasional stops for air. She finished the first bottle with relative ease, however, her slightly pudgy stomach had already started expanding, it wasn't that noticeable but a belly was starting to form. She started chugging the second one. About halfway through she definitely started to feel all the water in her stomach, looking down she saw her belly at least thrice as big as it was before. This motivated her to keep going. After she finished the second bottle, she was full, very full. She hesitated, but then she imagined her belly being enormous and she opened the third bottle. While chugging she was massaging her belly, it was getting very uncomfortable. With great effort she finished the third bottle. Her belly was now very big, her shirt was resting on top of her belly. She let out a small burp and opened the fourth one. "C-Come on... I have to push through..." She put it to her lips and started chugging, way slower than before. Her belly was sloshing a lot and every movement she made would have the water uncomfortably slosh around. Finishing the fourth one she leaned back. "Uuuuggghhh... I can't do it.... *burp*". She got a sort of adrenaline boost or something, because she quickly opened the fifth one and started chugging, double speed. Her belly was expanding rapidly, it wasn't prepared for this. Around 3/4 done she put it down. If she sat down, her belly could almost touch her knees. She didn't think she had ever been this full. She lay down and couldn't get comfortable. She suddenly picked up the bottle and drank the remains with slow a very, very slow chug. After every time she swallowed she let out a loud moan, much like her belly which was violently protesting. She finished, picked up the sixth bottle and did the same thing. She got around halfway through when she put it down for a final time. She couldn't move because it was hard to move with this huge orb of a belly and because every movement made all the contents of her stomach slosh around. Her belly was nicely round and looked quite hard but if you pushed it in it had quite a lot of give. She tested it herself and groaned. As full and uncomfortable as she was, she felt like she won something
