Poppy sighed heavily as she placed her backpack on her bed and slumped into her desk chair. School had been rough again. She just couldn't fit in, no matter how hard she tried. The group assignment in science class had ended up with her picked last and ignored the entire class period. She fidgeted with a pencil on her desk before sighing again, shoving her hands in her hoodie, and pouting. Her brother, Clover, was a shy dude but had WAY more friends than her. How'd he do it? Was there some secret to getting popular? She kicked her feet for a bit before finally getting up and heading to her brother's room to go hassle him. Hell, maybe she could even get him to take her along on one of his hang outs. 

"Clover?" She called gently before opening his door. She almost never knocked. He was sitting on the floor in front of his TV with a headset on, playing some game. 
"Guys, listen," Clover said to the headset, "they've got a shock drone and you're not even - oh my god really?" He scowled at the TV and Poppy carefully snuck up to him, shutting the door silently behind her. With a tiny yell she wrapped her arms around him from behind and he made a delightful "ACHK!" noise. 
"Poppy!" he yelled. "You better be glad this is push to talk. What the hell?" Poppy grinned.
"Take me with you to Eric's house tomorrow!" she said, the tip of her tail swishing back and forth excitedly.
"Absolutely not," he said. "Let me finish this game." Poppy pouted but kept her arms around him and her head on his shoulder while he played. 
"Well, looks like I'm dead anyways," he said after less than a minute. "Team sucked. Why do you want to go to Eric's place?"
"To hang out!" she said, grinning. He took off his headset and shook his head. 
"Eric and I are doing D&D tomorrow. I don't have the time to explain all the rules and- listen, just stay home okay?"
"Don't wanna," Poppy said, hugging him tighter. "Wanna hang out with you."
"You're acting like you're five. Isn't your thirteenth birthday coming up soon?"
"I just wanna hang out with you!" She said, burying her face in his back. He sighed. 
"Did something happen at school, Poppy?" he asked gently. She bit her lip and stopped hugging him, instead choosing to go to his bed and lay down on her side, facing away from him.
"It sucks," she muttered. "You have so many friends and get to do D&D and video games with people. You can go bike riding with your friends and you're gonna drive a car soon. I can't do shit."
"Language," he said. He sounded closer. 
"Sorry," Poppy said, "but it's true. You're like super popular and I saw the way Emily was looking at you too."
"Emily?" Clover sat down on the bed beside Poppy and gently placed a hand on her shoulder. "Emily's rude as fuck - sorry, rude as hell. I don't want to hang out with her even if she was looking at me." Poppy tensed at the touch.


"Besides," he said gently, laying down behind her and wrapping his arms around her, "Emily's not nearly as cute as you." Poppy's breath quickened. He was way too good at this. Any time she tried to bring something serious up with him, he'd find a way to make her brain short circuit. Clover's hand trailed down from her shoulder to her hip, and Poppy squirmed. 
"How about this?" he murmured against her ear. "I'll give you all the attention you want tonight, then tomorrow I'll hang out with Eric." He kissed her ear and Poppy muffled a gasp. He knew her weaknesses too. Ears were one of them. 
"N-no," Poppy said, voice muffled against the sheets. "I wanna hang out. I want...a friend to hang out with." Clover pushed his hand underneath Poppy's shirt and she gasped at the coolness of his hands against her warm stomach. 
"Sorry," he muttered. "Hands are cold." She shivered and pressed closer to him, and he pulled the covers up around them. 
"You're a jerk," Poppy said, gently taking his hand and guiding it further up her chest. "I got picked last in group today." He began carefully massaging his younger sister's budding breasts, nipping and kissing the back of her neck. She stifled a moan. Another weak spot.
"You'll make friends in high school, promise," he said as he continued fondling her and making her squirm helplessly. "Middle school is really vicious. Maybe I can show you how to play some of these online games later? You might meet someone..."
"What if they're like, ah, a creep?" she asked, briefly interrupted by the feeling of his lips brushing against her neck. 
"Then I'll kill them, like, obviously," her brother said. He said it with such conviction that Poppy knew it was true. He'd protect her with his life. And she would do the same thing for him - not that he needed much protection.  

Poppy's toes curled as he more aggressively moved his hands over her body, squeezing her barely noticeable breasts and pushing his hips against hers. She whimpered and pushed her hips back against his - and in doing so, felt her brother's stiff cock, barely contained by his gym shorts. 
"Poppy, front or back?" he asked. His voice wasn't as gentle as before, there was a slight edge to it. The sixteen year old had gotten less and less interested in the foreplay leading up to them messing around, not that it bothered Poppy. She kind of hated when he used to tease her for hours and hours until she had to go masturbate in her room. 
"F-front," she whined. "Can you please cum inside me tonight? Mom got me on that birth control again." He nodded, reaching down to help pull off her jeans. 
"We probably still shouldn't mess around with me cumming inside you all the time, though," he muttered as he took off his own shorts. Poppy whined. 
"But I like it," she said. "It makes my brain go all fuzzy." Clover sat up and pulled Poppy to face him, laying on her back. She looked up into her brother's eyes - which were oddly intense, yet affectionate. She reached up and touched his cheek, and he nestled his face against her hand.
"When you go into high school," he said, kissing her hand and wrist, "remember what I said? If you meet another dude?"
"Y-yeah," she stumbled, "no one else can cum in me - not in my mouth or ass or anywhere. Only you."
"That's right," he said. He leaned down and kissed her lips, while she wrapped her arms around him and lifted her hips against his, desperate to feel him closer. He giggled as they broke the kiss. 
"You're so cute when you're desperate," he said. Poppy pouted and whined and he ruffled her hair, laughed, and kissed her again. They both devolved into giggles as their bodies drew closer. Poppy ran her hands over him and hesitated only a moment before taking his boyhood into her hand. He twitched and let out a little moan. She smiled and gently stroked him, bringing his hips closer to her own. Thankfully he took the message and promptly moved her hand away, grasped her hips, and pushed in. The two gasped in unison, immediately sinking into each other. 

Poppy's soaked pussy made entry incredibly easy, and he pushed in as far as he could as soon as their hips connected. She hissed and dug her nails into his back, forgetting just how intense it was to have all 6 inches in her small pussy. Sure, he wasn't the biggest guy, but any bigger felt like it might split her tight pussy wide open. She muffled her moans against his chest as he began roughly slamming his hips into hers. Ever since he hit fifteen, he'd gotten really rough with the way he fucked her - which hurt, but in a way she loved. She gasped as he slammed as much of his cock in her as his teenage body could, his balls slapping against her loudly. She had a slight momentary panic trying to remember if she'd closed the door, but remembered their parents wouldn't even be home for another couple of hours. She let out a ragged sigh of relief that was sharply interruptted by a yelp as he slammed harder into her with a grunt. 

Clover grabbed his sister's legs and laid them on his shoulders. 
"C-clover that's gonna be too- oh my god," Poppy gasped as he slammed even deeper into her poor little pussy. 
"You're so tight," he growled, holding her as close as he possibly could. "Feels like you're gonna squeeze my dick off..."
"Clover," she whined as his hips and hers collided over and over. "Please."
"Please what?" he growled.
"Please cum inside me. Please," she moaned out. "I need it." They were both panting by that point, drenched in sweat but not taking off their shirts out of habit - just in case a parent came home early. 
"I'm gonna cum," he whined, thighs trembling as they reached their peak. Poppy couldn't speak, only moan as her own orgasm shook her small body and shuddered all the way up and down her spine. And just before she lost all real thought, she felt her brother give her a hard, final thrust, his whole body tensing as both their brains short circuited. Poppy thought she heard him call her name, but it was hard to grasp anything other than the warm rush of fluids inside her. Her brother's cum filled her small pussy to the brim as they twitched and gasped together. Despite her being on birth control, she had a strange thought pass her sex-addled brain - one about her brother impregnating her. As her body slowly wound down, images filled her head of her breasts getting bigger and milky and her belly expanding. Her brother cut through the fog by kissing her gently on the lips. 
"You alright?" he muttered. "You look like you went into space there for a second."
"Y-yeah," she said, looking up admiringly to her handsome older brother. "I was just...daydreaming." He smiled.
"I love you, Poppy. You're the best little sister ever."
"I love you too, Clover," she said breathlessly. "You're still kind of a jerk, though." He laughed.
