Here's a little story I wrote for a "friend" okay crush, whatever, stop judging me. Anyways, it was written very quickly (in between doing loads of dishes) and I didn't really proofread it so read at your own risk!
Alice smiled as she picked up the one-piece swim suit. Even though it was adult sized, it looked like something that a kid would wear. It was white with pink piping and a little pink bow at the waist. The straps had pink frills. It had a skirt, but it didn't go down far enough to cover the butt. It was hilarious. She nudged Rowan and held it up.
"Oh, you have to try this on!" said Rowan.
Alice's smile drained from her face. "No way! For one thing, I'm not wearing a gaff, so it's going to be bulge city down there. For another thing, well, look at it!"
"Dare you," said Rowan, a smile playing on their face.
"No," said Alice, shaking her head slightly.
"Fine, let's make it interesting. Try it on and if it doesn't fit, I'll buy three outfits for you. If it does, you have to buy it."
Alice thought for a second. It was so tempting.
"If it fits, you have to buy me at least one outfit."
"Deal," Rowan smiled and patted her on the butt. "Run along now."
Blushing from the pat, she hopped over to the changing booth. She quickly disrobed, leaving her panties and bra on, the uniform associated with trying on swimwear. She pulled it on and, to her frustration, it sort of fit. It didn't cover as much of her ass as she liked, but she was pretty sure it fit.
"Rowan," she called out, "I think it fits?"
"Prove it, or no outfits for you," was the reply.
"I am not coming out there!" She blushed at the thought, looking at the bulge in the swimsuit and blushing further. She yelped as the curtain opened slightly and Rowan popped in. They immediately burst into laughter.
"You look like a baby!"
"No I don't!" She kind of did but she didn't like it being said.
"Yeah you do. Dare you to suck your thumb!"
"What? No!"
"One more outfit!"
She rolled her eyes and sucked on her thumb for a quick second. Right at that moment there was a camera flash.
"Oh my god, Rowan, did you take a picture? Delete it! Delete it right now!"
"I'm not going to do that," they said with a chuckle, "At least not yet. Go pick out your other outfits."

Alice was quiet on the car ride home. Rowan had a smirk on their face that was worth the three outifts they had ended up buying Alice to soothe her mood. And yet, they could tell she was still a little pissed. She was about to get worse.
