"I heard you'd just arrived had to see it for myself." Sarah called out playfully as she ran into the barn to give her step-brother a huge bear hug. Throwing herself into his arms. Matt grinned at her and hugged her back. He held her away from him to see how much she'd grown in the three years since he'd last seen her. She had been a gangly sixteen year old when he went into the military. Now she had curves and her hair was nice and long easy to pull. He did so now listening to her squeal before she smacked at him. He licked his lips as she bounced away from him. He tried to pretend he wasn't feeling blood rushing south. She grinned at him.
"The army suits you big brother." She teased sticking her tongue out at him. He laughed and looked down at his uniform. He didn't care for it much but it sure got him laid enough so he couldn't complain. He ran his hand through his extremely short hair and looked at her again. Her d cup tits strained against her faded t shirt and her ass filled out her jeans so well he wanted to cup it and lift her up pressing his mouth against hers. But he looked away quickly. Forcing himself to think pure thoughts about his nineteen year old step-sister.
"Dad's still with your mom." Sarah said matter-of-factly. He nodded.
"Yeah I saw that. Kind of a shame isn't it?" He knew that Sarah didn't like his mom very much but then again he didn't like her dad and when they had gotten married both were miserable until they got to know each other. Then they had become best friends. But now looking at her he couldn't think of her as a friend. Or even his sister. Step or otherwise. He sat down in the straw and looked out at the perfect summer day before him.
"Where's mom?" he asked suddenly. Sarah grinned at him and then shook her head.
"Mom and dad are in town for the day. They'll be back later." She replied. Matt gave her a sideways look.
"So we are all alone?" he asked in what he hoped sounded like a brotherly manner. She raised an eyebrow at him and then laughed and nodded.
"That's nothing new though dad and Peggy where always lumping us together." She replied. Matt shoved her shoulder.
"Is that a bad thing?" he asked her.
"As long as you don't annoy me I don't see why it would be a bad thing."
Matt chuckled. "I'll try to stay out of your way." He promised. He quickly headed for the house being that close to her was defiantly hazardous to his health he decided. He looked down. Especially to his little buddy.
A few hours later Sarah heard a soft moan coming from the computer room. She paused outside the door and listened for a minute. She heard the unmistakable voice of Matt. Her heart raced for a few seconds. She pushed the door open a little bit. And peered around it at her step brother masturbating in front of the computer. Her jaw went slack for a full minute before she gathered her wits. She watched him stroking his cock with his hand and groaning. His head tipped back as he leaned back in the chair pumping his cock harder. She cleared her throat. He jerked up right and spun around his mouth dropping open in horror. He hastily tried to pull his pants up and fell out of the chair.
"Get out!" He screamed. She hit the door in her haste to get away from him. She ran to her room and slammed the door so hard the windows rattled. Then she flung herself on her bed and stared up at the ceiling. A few minutes later Matt knocked softly on her door.
"Hey, Sarah I'm sorry I yelled at you. You kind of startled me." He said. He sat down on the edge of her bed. She looked up at him and nodded.
"You startled me too. I didn't know a guy could be so...big" She said softly. Matt's head snapped up.
"W-what?" he finally managed to choke out. Sarah giggled at his shocked look.
"I've never seen a guy so big before." Sarah said. Matt swallowed hard.
"Oh?" he didn't really trust his voice. Sarah nodded again. "Well you see. I. the thing is. Oh hell." He mumbled. Sarah stared at him with fascination.
"Did you finish?" She asked suddenly.
"Excuse me?"
"Did. You. Finish? I didn't stutter."
"Well no but... Sarah what the hell are you doing?" He looked down to see her tugging on his shorts trying to pull them down. He grabbed her wrists to stop her. She looked up at him with a wicked little smile.
"Oh come on I know you want it. Why else would you have been masturbating where I'd be able to walk in?"
"I didn't even know you where in the house!" he sputtered.
