This is my first time writing a story, hope you enjoy it!

"Hey Alexa. Doing anything tonight? No? Want to hook up tonight? Denny's? How about 7 PM? See you then."

Steven was awed. Alexa and him were going out on their fifth date, andshe hinted at some "fun" last time he went out, and she sounded exceptionally naughty. This excited the sixteen year old so much, that he wanted to prepare himself. He was five feet, 10 inches.

First on the agenda, was to secure a car. His parents were out of town, and he had a drivers licensce, so he'd use his parents' car. His sister and girlfriend shared the same type of music, all he'd have to do was steal it before the muscular freak that was his sister came back.

He went into her room, and started digging through her messy room. Bra here, shirt there, spandex underwear...?? "What the hell?" that Steven, but he looked again through his sister's room, and found a good CD.

"Find anything you like?" Becca retorted, sounding very pissed off. She was fourteen, 4 inches shorter than Steven, but more muscular and covered in sweat, as she had been working out. "Yeah, your CD, I think I'll take it." Steven said as he waved her Goldfinger CD around. Then he started heading for the door.

"Forgetting something? I'm heavier than you, I'm stronger than you, and I'm able to kick your ass. Drop the CD and leave." She said. With that she grabbed his wrist and paused.

"Let go of me, you freak." Steve said. He could see fire in her eyes. "WHAT DID YOU SAY?" and pushed him into her dresser. "Drop it!" and grabbed his arm, and pulled it behind his back, and twisted it. He dropped the CD. "So, sis, what's with the spandex underwear?" Steve said. She looked at him, shocked, and blushed. He used this chance to break away, push her to her bed, and run off.

She instantly hopped up, and ran him down, being faster than him, and dragged him back to her room. "So, Mom and dad told you, huh? I made them swear not to tell anyone about it! And all this sweat and smell is working me up." Steve looked confused. She picked up on it. "So you don't know?" She forced him to his knees, and told him to stay there. Steve couldn't fight her, so he'd have to endure what was going on. Becca got up, and grabbed her 100 pound TV, and several 50 pound barbells and blocked her door off, so he couldn't escape.

"Let me show you what I mean, Steve. Never call me freak ever again." She dropped her pants and panties. Steve sat there, staring at her cock, standing up 8 inches erect. He tried to get up, thinking "What the fucl!?!?!" and she caught him again, and forced him to her knees, and wrapped her leg around him. He stuggled to get away, but she was too strong. She pulled off her top and her C Cup bra, and said, "Ya know what? I've never wanted a big brother. I've always wanted a little sister. From now on, you are that sister, are we cl
