James Austin’s weathered treehouse creaked in the wind. His dad built it for him years ago. An official gang was formed by four neighbourhood kids, the “Treehouse Gang.” James, Tommy, Danny and Sofia (the eternal tomboy). They were the only ones allowed to enter past the no trespassing sign. Emily, James’s sister cried and cried, but she was never, ever, allowed up. It the first club rule Tommy made. He was the unofficial boss.

All the gang members were older now, excited to be teens and not pre-teens. Thirteen was a big deal. Sofia chest was flat as a board and then one day, she had breasts. Not big ones, more like bumps with pencil-sized nipples. Sofia hated them, and it seemed like they were growing bigger every day. She still dressed like the boys in jeans and t-shirts, but now her mom forced her to wear a “training” bra. To hide her boobs. It was the worst day of her life.

In the treehouse, an empty plate sat next to Tommy, he ate the last chocolate cookie James’s mom had made for them. Tommy was the club leader, what he said was law. He was also the biggest and strongest.

“So,” Tommy murmured looking at Sofia’s chest, “you have to wear a bra now?”

The other boys were more introverted than Tommy, but this gave them an excuse to stare. And stare, and stare.

Sofia shrugged. “It’s no big deal, I’m still one of the Treehouse Gang.” But inside she was worried they would throw her out, because she was a “girl.” Girls weren’t allowed in the treehouse unless they were Sofia. That was another rule.

Tommy leaned forward, his face inches from hers. “We have rules, no girls. What am I going to do with you now? I have to enforce them. Damn, Sofia, why did you have to grow tits!”

She held back the tears threatening to run down her blushing cheeks. “I didn’t want them to, Tommy! Can’t we all just continue to be friends? It’s no big deal.”

“No big deal? None of us can stop staring at them!” he thundered getting up and pacing in the eight foot by eight foot space. “I mean look! I can see your nipples poking out! How are we supposed to not look?”

That did it, Sofia started crying, not soft sniffles, this was full all out bawling at the thought of losing her best friends.

“Tommy, stop being mean to Sofia!” Danny shouted, “she’s still one of us.”

James nodded, “Yeah!” But James’s eyes were stuck on Sofia’s chest and the bouncing action.

Tommy paced some more deep in thought, then smiled. “Okay, but she needs to prove she’s still one of us.” He crossed his arms and pulled his t-shirt over his head. “Everyone take off your shirts.” He looked at Sofia. “That means you too. And your bra. Or else, you’re no longer in the gang.”

Danny and James stared at Tommy’s smirking face. None of them had seen a girl’s boobs, Sofia would be their first. Danny quickly followed Tommy and then reluctantly James obeyed. They all turned to Sofia who had her back up against the stained plywood wall.

“You don’t have to Sofia,” James whispered, “even if you get kicked out of the Treehouse Gang, I’ll still be your friend.

Sofia looked around the well-built treehouse and good memories flooded her mind. Then she looked at her three best friends. She stopped sniffling and wiped her nose with the back of her hand. “Do I have to, Tommy? Isn’t there another way?” She would do anything to stay in the gang, but this seemed like a huge step in the wrong direction. The gang was her entire life.

“Let’s get one thing clear Sofia. None of us are forcing you to do anything. The choice is yours and yours alone. If you do it, you can stay part of the gang. But if not, that’s okay too, but you can never climb up and come in the treehouse ever again. You can go play dolls with Emily.”

Tommy turned to Danny and James, but they didn’t challenge him. Instead, they nodded in agreement. Danny was anxious to see Sofia’s boobs, even if they were small. Danny could feel his cock getting hard and he used his hands to hide it from Sofia.

All the boys were standing looking down on her. Waiting. Sofia stood up and looked at the trap door to wood steps leading fifteen feet to the ground. Unless she did what Tommy wanted she would never be allowed up here again. She hesitated, then lifted her shirt over her head and unhooked her bra in one swift movement.

She stood there in front of her best friends, topless. The cold air was her enemy and it made her nipples harden.

Tommy couldn’t stop grinning from ear to ear. He didn’t think Sofia would do it. Danny whistled. James gulped.

“There, I did it,” she said softly. “Am I still in the gang?”

Tommy nodded stepping forward, “You’re in Sofia. Group hug!” he shouted being the first to feel Sofia’s breasts against his bare chest. Then Danny and James were hugging her to.

Danny was looking down at her boobs. “Do they hurt? Can you feel them ... growing?” Tommy hit him across the back of his head.

“Of course not, dufus, it happens to all girls. Like how your dick got hard in your pants looking at Sofia.”

Danny blushed. “Sorry, Sofia, I can’t help it. Your ... breasts are beautiful.”

James rolled his eyes, “Wow! Danny’s got a boner.”

Sofia shrunk as the boys talked about her like she wasn’t there.

“Now, a better question would be, how do Sofia’s breasts feel.” Tommy looked at Sofia to see if she would scream or fight. He was a little scared to try, Sofia had a wicked punch. “And ... I get to be the first, because I’m the leader.” He never waited for her permission. Reaching out with both hands his fingers wrapped around Sofia’s breasts and squeezed. “They’re soft, but firm. Look, when I touched her nipples they grew! Fire!”

Tommy stepped back. “Okay, Danny, your turn.”

Danny hesitated, “Can I, Sofia?”

Sofia shrugged, “Okay, but don’t squeeze as hard as Tommy did.”

Danny nodded and his hands shook as he gently touched Sofia’s breasts, rubbing his thumbs across her nipples. “Wow! They’re warm and soft, but your nipples are hard.” He rubbed them faster. Sofia was breathing heavier now and her knees were getting weak.

Jealous that he didn’t make Sofia moan, he pushed Danny away. “Okay, okay, that’s enough, James’s turn and then me again.”

James gulped, the other guys didn’t know it, but he was in love with Sofia. He licked his lips and leaned forward scared to hurt her. Sofia gasped and held onto his shoulder with one hand and using her other hand on the wall for balance. This was so unexpected. She didn’t know having her breasts touched like this would feel so good. Even if it was from her best friends.

Tommy stood back and watched Sofia’s face as James touched her breasts. He smiled when he saw Sofia unclench her fists, that meant she was enjoying this. His dad was right, all girls were sluts, they just needed to be trained from a young age. And Sofia was the perfect age to start. His Treehouse Gang was going to be a lot more fun from now on. His mean streak was showing, the one that made his “friends” turn humble and submissive to him. He was their bully.

“James!” he snapped, suppressing a chuckle as James dropped his shaking hands and almost fell to the wood floor. “Come to me, Sofia, I want another turn.”

Sofia hesitated, she never liked the way Tommy ordered them around, like he was the boss, but she obeyed him and walked over to him, biting her lower lip.

“Turn around.”

She gave him a surprized look then pivoted. The next thing she knew her arms were trapped and he was squeezing her breasts with both hands. And he wasn’t gentle about it.

“From now on, when I say strip off your top, you do it. No fucking complaining, crying, or hesitating. You obey me and only me, not Danny or James. I’m the leader and I make the rules. You’re lucky I let you stay, I could have kicked you out for being a girl. But this makes up for it.” He squeezed tighter, twisting her nipples between his fingers.

Sofia winced, then nodded. When he got that sound in his voice, he got mean and dangerous. She had seen him fight boys much older than him and win, “Okay, Tommy. Thank you for not kicking me out.”

Tommy grinned, he was going to start training Sofia. “Now, Sofia, one day soon, not now, I’m also going to order you to strip naked. Take off your top, bra, jeans and panties. You’re going to stand in front of us naked and let us touch your slit. I will make up new rules as we go forward.”

Sofia’s stomach dropped. Tommy wasn’t going to stop tormenting her until he saw everything. She winced when he twisted her nipples, but she didn’t say yes. That was going too far. Wasn’t it?

Danny and James, shirtless, shifted nervously. They looked at each other, but neither of them were big enough or brave enough to challenge Tommy. Danny’s cock was extra hard in his pants now.

Tommy twisted her nipples harder. “If you don’t obey me, you’re out.”

Sofia gasped, the pain was sharp, but she wouldn’t cry in front of him. Not again. He knew she was scared of him. What she didn’t expect from him was the sudden kiss on her lips or the way she obediently opened her mouth for his tongue. His hands were massaging her small breasts in a different way now. And that feeling returned in her tummy.

Tommy broke the kiss off. “I like you, Sofia, but girls are not supposed to be in the Treehouse Gang, that was the first rule I made. I let you in when you were one of us, but now that you grew boobs that changes everything. And you got a hole instead of a cock. You need to show us what your cunt looks like.”

Sofia took a deep breath, then nodded. “Okay, Tommy. But ... not today, okay? This is as far as I can go today.”

Tommy grinned, his training of Sofia was off to a good start. “Okay, but hold still while I feel up your boobs! You’re fussing is spoiling it for me.” Then he looked at Danny and James. “You guys have anything to say?”

They shook their heads, staring at Sofia’s breasts in Tommy’s hands. They couldn’t believe one day soon Tommy was going to get Sofia to strip completely naked for them.

Tommy was having a good time, he was going to make Sofia obey him like his mom obeyed his dad. Her mouth and slit were going to learn what she was made for.

He kissed Sofia again and this time she kissed him back. Tommy snickered. His Treehouse Gang was going to have a lot of new rules in the future and all of them directed at Sofia. He turned her around and looked into her innocent blue eyes. “You need to learn how to kiss properly. When my tongue is in your mouth that means you suck on it. Now try again.”

With her bare breasts pressed against Tommy’s chest, Sofia rose on her tiptoes and kissed him. She tasted chocolate from the cookies James’s mom made for them. Tommy ate the most. His tongue slipped into her mouth and ... she sucked.

Tommy pulled away. “Not good enough.” He squeezed her ass through her jeans. “Last chance.”

Sofia kissed him again, this time she sucked harder on his tongue and hugged him as tight as she could. His hand slipped into her jeans and panties. He was touching her bare bum. She flinched but didn’t stop kissing and sucking.

Danny gulped in amazement at what Tommy was making Sofia do. His cock twitched so hard he wanted to rub it. James looked over at him and they high-fived each other.
