Now he had done it. She couldn't remember the last time she'd been this angry. Even looking at his stupid face, however cute- with his blue, puppy-dog eyes and those long lashes blinking back at her- couldn't quench her fury.
"What's wrong sis'?" he asked, as though nothing was wrong at all.
She slowly strode up to him, her hands balled up into trembling fists. She stood above him, towering above the small teenager. Then she pounced. It didn't take much effort to take him down. Quinn, a skinny, 5'4" young man, had never been a fighter of any sort. It had always been Autumn, the older sibling, who stepped up for him, who fought bullies and threw punches. Even now, at the age of nineteen, Quinn was hardly what she would call a "man." He was slender- lithe even- but not strong, and nearly hairless. His shoulder-length blonde hair framed a delicate, effeminate face with high cheekbones and pouty lips. In just a few seconds she had his arms pinned down under her folded legs, sitting on his chest.
"W-what the hell, Autumn!?" Quinn stammered, trying but hopelessly squirming to free himself.
Autumn started to answer with her original fury, but as she sat there, hovering above Quinn, a wicked thought crossed her mind. It was a brief thought, but long enough to give her an idea. She realized what his punishment would be.
"I'm so fucking tired of you not taking care of my stuff. It's about time you pay." she said quietly, reaching for the zipper to her denim shorts.
"Okay, okay," he said angrily, "but that..." he paused, realizing what she was doing, "that hurt..."
Having unzipped her shorts, she reached in and slowly pulled out her flaccid cock, letting it drop down to smack Quinn in the face. Unblinking, his questioning eyes darted from her large member to her face and back down again. She picked her cock back up and began to stroke it, occasionally pausing to brush it across his face. It wasn't long before she was at full mast- 7 inches of uncut girl-dick hovering above her brothers face. Every bit was shaved; the shaft silky, stretchy, and perfect; her balls hung deliciously smooth and pliant. She then shimmied herself back so she could gently push the head of her cock against his plump lips.
Before she could say anything to persuade him, Quinn closed his eyes and engulfed her head. She almost squealed at the sensation, but managed to quickly regain control of herself. His tongue worked magic, lapping at the pre-juices leaking from her slit and rolling around the glans. She sighed with pleasure as he slurped in earnest. He alternated between sucking tenderly on the tip and rolling his tongue under her foreskin. She reached down and pulled her cock from his mouth, making an audible 'pop' as it left his gentle suction. She pulled the foreskin back to reveal her inflamed head. Quinn's beautiful blues eyes watched intently as she moved her hand back to the base and pushed her cock back into his face.
"Lick it," Autumn whispered. His little pink tongue quickly shot out to lap at the frenulum and the supple skin just past the head. As he kissed and lolled his tongue over her cock, Autumn slowly realized how into this Quinn was. Then, in a flash of memories, she relived all the strange little moments she'd had with her brother. All those times she caught Quinn looking longingly at her, or saying suggestive things but never taking the plunge. She had always thought these moments were Quinn being a bit quirky, showing a truer side of himself that others didn't get to see. Now as she looked down at Quinn, caressing and licking the base of her cock, she felt her heart swell. She re-positioned herself to lay her large balls on his mouth. He began to caress them as he'd done with the rest of her cock. After giving each some loving attention he took one in his mouth. He rolled it from one side of his mouth to the other, now gazing back up at Autumn. Letting go of her balls he began to move back up the shaft, giving a long, sensual lick from the base to the head. Finally this gentle eroticism was driving Autumn crazy- she needed more.
