Ryan quietly pushed open the door to Millie's bedroom, expecting to find her sprawled out on her bed, nose buried in a book. Instead, he was met with a sight that made his heart race and his mind go blank.
Millie was on her hands and knees, her tiny bare ass in the air. She looked over her shoulder and grinned when she saw Ryan. "Hey, Ry. I'm glad you're here. I need to talk to you about something."
Ryan blinked, trying to regain his composure. "Uh, sure Millie. What's up?"
Millie wiggled her ass suggestively. "Well, I was thinking...you know how we've been hanging out a lot lately?"
Ryan nodded, still trying to process the sight of Millie's bare ass. "Yeah, of course. We're best friends."
Millie pouted. "But I want to be more than just friends, Ry. I want to be your girlfriend."
Ryan took a step back, surprised by Millie's sudden declaration. "Millie, you're only thirteen. I'm sixteen. It's not appropriate for us to date."
Millie huffed, crossing her arms. "You're just a prude, Ry. I bet you've done it with other girls."
Ryan felt his face heat up. "That's not the point, Millie. Boys and girls are different. We can't do the same things."
Millie rolled her eyes. "Please, Ry. I can be just like a boy for you. I promise."
Ryan couldn't help but laugh at Millie's persistence. "You're too young to understand what you're asking for, Millie. It's not appropriate for us to engage in that kind of behavior."
Millie's bottom lip jutted out in a pout. "Fine, be a tease. I'll just find someone else who will give me what I want."
Ryan's laughter died in his throat. He couldn't deny the attraction he felt towards Millie, even if it was wrong. He tried to distract himself by focusing on the inappropriateness of the situation.
Millie noticed Ryan's growing arousal and used it to her advantage. She wiggled her ass and told Ryan how much she wanted him. "Please, Ry. I need you. I've never felt this way before."
Ryan tried to resist, but it was no use. He couldn't take it any longer. He decided to give in to Millie's request, but only on the condition that she didn't tell anyone and understood that this was a one-time thing.
Millie eagerly agreed to Ryan's terms. She positioned herself on the bed, ready for him to take her. Ryan hesitated for a moment, still unsure if this was the right thing to do. But the sight of Millie's tiny, preteen asshole was too much for him to resist.
He slowly started to penetrate Millie, who let out a small gasp of pain. Ryan reminded her to relax and take deep breaths. Millie started to get used to the feeling of Ryan inside her. She told him how good it felt and how much she loved him.
Ryan couldn't believe how tight and warm Millie's asshole was. He started to thrust deeper and faster, unable to control himself. Millie begged Ryan to "fuck her harder" and "be her boyfriend." Ryan tried to ignore her words and focus on the physical pleasure.
Ryan reached his climax and collapsed on top of Millie. They both lay there, panting and sweating, trying to catch their breath. Ryan knew that he'd made a huge mistake, but he couldn't help but feel satisfied in the moment.
Millie looked up at Ryan with a satisfied smile. "See, Ry? I told you I could be just like a boy."
Ryan couldn't help but laugh. "Yeah, you sure did." He knew that this was a mistake that they both would regret, but for now, he was content to lay there with Millie, their bodies still entwined.
