When you realized who you were placed beside, your face turned white. Standing right behind you was your annoying little sister, Zelina. You say little only because she was younger than you, but she was actually noticeably bigger than you, about the same size as an average six year-old girl. "Jack?!", your sister cried out. "I'm telling Mommy you ran off without someone with you!"
"Sh-shut up!", you snapped as you pouted and looked up at her as she stuck her tongue out at you. "Besides, you didn't have anyone with you, either!"
"Yeah she did, you dummy!", said a shrill voice behind you. You turned around and saw a fair-skinned, rather bottom-heavy girl around your sister's height with black hair and green eyes. She was wearing a seafoam green swimsuit and a pair of white sunglasses on top of her head with a flower design on them.
"I don't even know who you are!", you exclaimed before your sister shoved you.
"Hey, don't talk to my friend that way!", Zelina yelled at you. "Sorry about my dumb big brother, Nattie", she said to her friend.
"That's your big brother?", your sister's friend asked as she patted your head. "But he's so short and wimpy. You sure he's not your little brother?"
"Quit making fun of me!", you yelled up at the girls, trying to swat them away. You're very quickly regretting going off on your own. "I'm gonna tell Mom!"
"Nu-uhhh!", Zelina said in a sing-song tone. "Cus you're gonna get in trouble for running off if you do!"
Suddenly, Nattie grabbed your cheeks and stretched them out. "Haha! You were right, 'Lina!", she laughed. "He's just as squishy and stretchy as you said he was!"
You tried to swat them away again, only for Zelina to press up against you, squishing your face between their arms as she whispered something in Nattie's ear. Because your ears were covered, you couldn't hear what she was saying, but whatever it was, it brought a creepy smile on her friend's face as she began to whisper into your sister's ear. Once they had finished, they separated and you were returned to your head slowly re-inflated. Zelina then gave you a hug. "I'm sorry for picking on you big brother", she said in an almost mocking tone.
"Yeah, we won't mess with you anymore", Nattie said, with a snicker that made you more than a little suspicious. Because the three of you were nearing the front, however, you doubted that they'd do anything to you now.
"Fine... just leave me alone once we're off the ride." You were ready to be rid of these two bratty girls.
As you made your way to the front, you were greeted by the same employee that had broken up the crowd, who rolled her eyes as she saw the three of you approach, while Nattie stuck her tongue out at her. They seemed to know each other. Nattie went first on her stomach, briefly looking back before she went down. As you walked near the opening of the slide, you heard the familiar cackle of your sister before you were pushed over into the water, falling flat on your belly right after Natalie, with Zelina jumping in right afterward.
You yelped as you hit the cold water, and blushed as you saw Nattie's feet and her big round bum staring right at you, but your attention was quickly grabbed by your sister's feet hitting yours. As the three of you gained speed, you quickly realized what was about to happen, but you were powerless to stop it as Zelina lifted her legs just as you all hit the water! Nattie dove in, and you were pushed face-first into her rump, with Zelina being forced forward, squashing you between both of the girl's butts! Because you and Nattie were underwater, no one saw what had happened, nor did they hear it. The girls laughed at their prank as they got up. "That was hilarious!", Nat giggled.
"Yeah!", Zelina snickered. "I wonder which one of us my brother got stuck to."
"Oh! How about whoever he's stuck to gets to keep him for the day!", Nattie suggested.
"I dunno... my mommy might get upset if he doesn't show up..."
Zelina's hesitation was quickly broken as Nattie gave her puppy dog eyes. "Pleeease... It'd be really nice..."
Zelina blushed and smiled. "A-alright... Let's check and see..."
Both of the girls inspected themselves to see which one of their rear ends you were plastered against.
