It was a sweltering summer day when the world shifted for ten-year-old Bobby. He lay sprawled on his bed, sweat pooling beneath his skin, staring at the ceiling fan as it lazily circled above him. His heart pounded with an urgency he couldn't quite place. He shifted uncomfortably, feeling the familiar tightening in his groin as his insistent erection sprang up again. He sighed. He was always horny these days, but nothing seemed to satisfy.
And then, the sound of the front door opening jolted him back to reality. His parents were finally home from the hospital with his new sister. He sighed, tucking his small erection into his pants and forcing himself to stand up straight. As he walked down the hall to greet them, he couldn't help but feel annoyed that he'd been interrupted from his thoughts.
His parents beamed with pride as they presented their new bundle of joy, Beth, to him. He forced a smile and hugged them both, but it was the bassinet that caught his eye. His mother had peeled the blanket off, revealing the tiny baby girl within. She was so small and delicate, with a head of wispy dark hair and the tiniest fingers he'd ever seen. He felt his heart race and his cheeks flush as he struggled to maintain his composure.
He stared at her for what felt like an eternity, watching her tiny chest rise and fall with each breath. The urge to touch her was almost overwhelming, but he forced himself to stay back. His sister. His sister was here, and he had feelings for her that he didn't understand. He wanted nothing more than to hold her, to kiss her soft cheek, to strip her clothes off and reveal the smooth, pale skin beneath. But he didn't let any of those thoughts show on his face.
Instead, he smiled and congratulated his parents again, forcing himself to act normal. As they chatted about the baby's arrival, he couldn't help but steal glances at her. His heart pounded in his chest, and his palms were slick with sweat. He felt like he was on the edge of something, but he didn't know what. He couldn't tell if this was normal or if he was a monster. He waited for the right moment and politely excused himself, shutting his bedroom door and exclaiming a yell into the muffling cloth of his pillow.
"FUCK!"
He took a deep breath, trying to regain control. He couldn't believe this was happening. He loved babies, always had, but this was different. This was...more. He felt a deep, primal urge inside of him, and it terrified him.
He sat down at his desk, his fingers trembling as he typed in his search query. "Am I attracted to babies?" The results page filled with articles and forums discussing pedophilia and infantile sexuality. He scrolled through the pages, feeling increasingly sick to his stomach. It made some sense, he supposed. While he found the girls at school pretty, he couldn't really picture himself with one of them. He never liked porn as much as his friends did either, finding it a little bit gross. He'd never thought of a baby that way before, but that didn't change what he felt now.
Feeling his heart pounding, he typed a new term into the very same search bar that had once shown him naked women who did nothing to ease his hormones. He watched the thumbnails load, and he knew for sure.
He clicked through pictures of naked infants for an hour, at least. Tiny puffy pussies and tiny baby cocks, round chubby asses and pudgy tummies. That was the answer. He had never been more painfully hard, and he knew that the objects of his desire were babies. Why wasn't clear, but it was true.
He tried to shake off the thought, but it kept coming back. The more he tried to ignore it, the more he found himself drawn back to the images. He knew what he was doing was wrong, but he couldn't stop. He was addicted to the feeling of desire and shame in equal measure.
He came his clear, thin ejaculation from his small preteen cock, biting his lip to keep from screaming. The best orgasm of his young life, but he already knew it wasn't enough.
"I won't hurt her," he murmured softly to the empty room. But he knew he would touch her all the same.
Over the next few days, Bobby found himself drawn to the baby's room like a moth to a flame. He couldn't help but steal glances at her when he thought no one was looking, his heart racing every time he caught a glimpse of her tiny, perfect form. He forced himself to stay calm as his mother taught him to care for her, to barely look when he changed her diaper. He knew it would happen. It was just a matter of time.
Beth was three weeks old. His exhausted parents left him with her for the night, while they had a romantic night out. He forced himself to wait twenty minutes, to be sure they were really gone. Then with equal parts fear and excitement, he lifted her tiny body from the crib and brought her to his room, placing her on his Star Wars bedspread. Beth smiled up at her big brother.
He sat down next to her, staring at her tiny, perfect body. Her rosebud lips, her tiny nostrils flaring as she breathed. The soft, downy hair on her head, soft as silk. He couldn't help but lean in closer, his face just inches from hers. He breathed in her sweet, innocent scent, feeling his heart race.
Slowly, he began to undress her, his fingers trembling with anticipation. He pulled the shirt over her head, revealing her plump, chubby tummy and soft, pale skin. He traced a finger along her collarbone, feeling the delicate bones beneath her skin. He leaned down, pressing a gentle kiss to her forehead, tasting the sweetness of her skin.
As he continued to undress her, he couldn't help but marvel at her tiny, perfect body. He unbuttoned her pants and slid them off, revealing her diaper and plump little thighs. He reached out, cupping her flat breasts in his hands, feeling the soft, pink nipples as they went hard from his fingers. He leaned down again, this time pressing his lips to her tiny, rosebud lips, feeling the softness of her mouth against his own. Instinctively, her tongue explored his lips, and he gently sucked it, swooning at his first real kiss.
Their tongues danced together, exploring each other's mouths. He couldn't believe how good it felt, how right it seemed. He pulled back, gazing into her eyes, seeing no spark of recognition in them. Of course Beth still smiled at her brother, with no idea how twisted this was.
Bobby's heart raced as he continued to undress her, his hands shaking with anticipation. He undid her tiny diaper and slid it down her legs, revealing her perfect little cunt, plump and delicate. He leaned in closer, taking in her sweet, innocent scent. He breathed in deeply, feeling his entire body tingle with desire.
Gently, he parted her legs, revealing her chubby, pale thighs and the tiny cleft of plump flesh that guarded her most intimate parts. His cock, still hard from earlier, throbbed in his pants as he gazed upon her. He couldn't help but marvel at the perfection of her body, the innocence in her eyes.
He leaned in closer, his lips brushing against her soft skin. He felt his heart race as he placed a tender kiss on her inner thigh, feeling the warmth of her flesh against his lips. Slowly, he trailed his lips upwards, stopping to press a gentle kiss to her plump little clit.
"Bah!"
Beth let out a soft, surprised babble, her eyes focusing on her brother's mouth with interest. He smiled, feeling a rush of affection and desire course through him. His fingers moved to her little opening, teasing it gently as he continued to kiss her clit. He watched as her chest rose and fell with each ragged breath, her tiny fists clenching and unclenching at her sides.
As he pressed his lips to her slit, tasting the sweet nectar of her arousal, Beth let out more soft babbling and cooing, her legs wiggling with pleasure. Her brother's tongue danced over her bud, teasing it with gentle flicks and licks. She squirmed beneath him, her hips arching towards his face. He couldn't help but feel a sense of awe at the power he held over her, the ability to bring her so much pleasure with nothing more than his tongue.
He continued his ministrations, sucking on her clit as he explored the depths of her little cunt with his pinky finger. She let out a high-pitched squeal, her entire body tensing as she shook with her first orgasm. He held her tightly, feeling her tiny body quiver and shudder in his arms. Her sweet, innocent scent filled his nostrils, and he couldn't feel bad about what they'd just shared.
"Now can you make me feel good, sweet Beth?"
He pulled down his pajama bottoms and exposed his small, hard nail to her. Still red-faced from her orgasm, she didn't notice his cock until he waved it in front of her face like a rattle. She giggled with delight as she grabbed this new toy.
"That's right, Bethy. Play with it."
Bobby lay back on the bed, watching his sister explore his cock with wide-eyed curiosity. Her tiny hands wrapped around the shaft, and she tugged gently, causing a wave of pleasure to wash over him. He closed his eyes, enjoying the sensation as she sucked on the tip, her tongue darting out to tease the sensitive flesh. Her saliva helped lubricate his cock, making it slide easily in and out of her mouth.
The feeling of her lips wrapped around him was incredible, and he could feel himself getting closer to the edge. He reached down to stroke her hair, encouraging her as she explored her new toy. Her tiny mouth worked, taking more of him inside her, and he couldn't help but moan with pleasure.
"I love you, Beth."
Bobby's voice was thick with desire as he encouraged his little sister, Beth, to take all of him into her mouth. His prepubescent size was just perfect for her small mouth. He closed his eyes, feeling the pleasure build inside him as she suckled contentedly. Her saliva slid along his shaft, lubricating it perfectly, and he could feel himself getting closer and closer.
"That's it, Bethy," he whispered, stroking her hair. "Fuck, I'm cumming!"
As he groaned with pleasure, Beth cooed around his cock, her eyes shut with contentment. Her tongue flicked out, tasting the salty fluid that leaked from his tip. She swallowed reflexively, not even realizing what she was doing.
As Bobby's orgasm subsided, he gently pulled Beth away from his softening cock. He quickly replaced it with her pacifier, and she sucked happily, staring up at him with love.
"Thank you, Beth," he whispered, rubbing his fingers along the silky down of her hair. "That was...amazing."
Beth gurgled and sucked contentedly on the pacifier, her tiny fingers curling around her brother's. She looked up at him with adoring eyes, and he felt more satisfied than he ever had in his life.
When his parents came home after ten, they found him fast asleep in the chair beside the baby's crib. They smiled and carried him to his own bed.
They were so lucky that their boy cared so much for his baby sister!
