Olivia and Mia

"Me next!" another girl cried out.

It was Olivia. "For the skins team?" Madison asked, a slight frown on her face.

Olivia nodded, "Yes, ma'am. If we're gonna be topfree with the boys, I figure I might as well be able to win and avoid whatever the penalty is."

Madison smiled, though there was a bit of confusion behind the smile. "Well, I guess that makes sense."

Mia's hand went up next. Mia stood up, even taller than Madison, and she had her hand held high above her head. "I'll... Um... Be... On the... Skin... Team?" Mia stumbled over her words, clearly trying to be as ladylike as possible, especially since the other girls would be watching her closely to see how she handled herself. Madison was surprised by the boldness, but Nate had already read Mia's mind: Mia was an introvert who struggled with self-confidence, but when she felt pressured, or like she had to do something in by her sister, it was one of the few times when she could actually stand tall and assert herself. Olivia couldn't help but admire her sister's bravery.

Nate grinned at Olivia and Mia. "Excellent! You two will be a great addition to the team!"

Nate's eyes lingered a bit longer on Mia, admiring her cleavage and the fact that it was practically spilling out of her gym top. Her breasts were large and round, and they hung perfectly in a deep valley between her soft, smooth shoulders.

Mia blushed at the praise, but it didn't quite reach the level of embarrassment of when Nate was looking at her. Mia loved that he complimented her, and it made her feel good.

"Well, come on, you two!" The Coach yelled. "If you are on the Skins team, you have to put your shirts off. We're not here for you guys to make us wait!"

The two sisters took their spots, and Nate watched them take off their shirts. Olivia's breasts bounced slightly, but Mia kept her arms down, holding her shirt together under her chest.

Coach Markowski came over to the shy girl and patted her shoulder. "Don't worry, Mia. You can be proud. Show those boys what you've got."

Mia shook her head. "But... But, Coach..."

Markowski rolled her eyes. "What? This is the first day, you don't even have your boobs out yet. Don't worry about it."

Nate came over to assist the panicking Mia. "Come on, Mia. You're gonna be great."

Mia nodded. "Yeah, okay. I'll try."

Mia pulled up her t-shirt. Mia was definitely bigger than Olivia, and had the full, round, bouncy tits that Olivia had. Unlike her sister, however, Olivia wore a white lacy camisole, rather than the more conservative blue one Mia had been wearing.

"Excuse me you two, but the game is shirts vs skins, not shirts vs bras. If you wear any bra, we'll have to replace you."

"What?!? But... But why?!" Mia stammered, her eyes wide with panic. Olivia just stood there, confused.

Coach Markowski answered, "Just that, Mia, if you're were a guy, then it doesn't matter what type of top you wear. You'd be on the shirts team. So if you want to be on the Skins team, you need to be topfree!"

Mia's eyes darted back and forth between Olivia and Nate. "Oh. Okay. Well, um, I guess, yeah, maybe I should go on the shirts team..."

Markowski's eyes gleamed. "Are you sure you don't want to try going completely topless? You get to be on your sister's team, you have a lot of fun, you can win, you might avoid getting hit with the penalty, and it looks pretty sexy!" the coach smiled.

Mia bit her lip, considering it. "You know, you're probably right..."

Olivia was surprised by her sister's willingness to strip, but she couldn't help but smile. Olivia's mind flashed back to the vague memories when Nate had stripped in front of her, but then were wiped by Nate after he had his fun. Olivia felt herself blush as she imagined the rest of the class looking at her, but her shyness could not overpower her desire to do this for her sister. "Okay, Mia. You can be proud. Show them what you've got."

Mia seemed to bounce back after hearing that, and gave her sister a quick peck on the cheek, "Thanks, Oli. Now, let's get our clothes off, so we can play the game."

Nate watched Mia strip, and her body was quite the sight. Her breasts were huge, and the blue camisole that she had on barely contained them. She began to lower the straps, and her breasts sprung out, bouncing lightly as they came free from the confines of Mia's bra. Mia took her shirt off, revealing a deep valley between her firm, round tits. Olivia admired her sister, and noticed how Nate kept staring. Mia caught him ogling, and shot a playful glare.

Olivia blushed. "Um, sorry. This is the first time I've been topless around others since we were kids, so it's a little weird, you know?" Olivia glanced down, feeling embarrassed.

Nate shook his head. "No worries. Olivia, you have great tits!"

Olivia giggled. "Thanks, Nate. That's sweet of you to say."

Nate leaned in close to Olivia and whispered. "And your sister has a nice rack too. Let's hope you can beat her, because Olivia, you have a fantastic pair of knockers. And I can't wait to see you on the court with those bouncing beauties. What do you think, Mia? Are you ready to show us a real set of boobs?!"

Mia bit her lip, her cheeks flushing. "Yeah, um... Yeah, okay. I guess so..."

Mia slowly unhooked her bra, and pulled them down. Nate gasped. Mia had the biggest, most perfectly shaped breasts he had ever seen. Mia's chest was round, soft, and full, with the deepest cleavage Nate had ever seen in person. Her breasts hung low enough that the sides of her breasts had touched the bottom of her belly button when she bent over to adjust her strangely tight gym shorts. Mia stood up straight, letting her tits hang freely.

Mia's skin had a golden hue to it, and she didn't have the same sort of toned muscles that Olivia did. But her body was incredibly sexy, and her large, heavy, round tits drew Nate's attention like a magnet. Nate couldn't believe how gorgeous Mia's breasts were.

Nate smiled, "We're gonna win this one, Oli. Your sister's tits are spectacular, and they're going to make everyone lose focus." Olivia laughed, giving Nate one of her trademark hugs, forgetting that her breasts were hanging out. Olivia blushed, and Mia shot Nate a bashful grin.

Nate and the rest of the guys were insanely confused. Why were three girls on the Skins team? Why were there three girls practicing basketball while they were topless? Nate was especially confused, he didn't use his powers at all!
