Before you start reading this, I am sorry about the previous posting of this story. Something, somewhere, somehow, caused several repeats to appear in it of the same paragraph. I cannot recall the name of the person that pointed it out to me, but if you happen to read this, I thank you for letting me know.
Now on with the story.
___________________________________________________________
The house was quiet as Jeff opened the front door. He thought that someone would be here to welcome him home from college for the holidays, but there was no one to be found.
"Hello?" He called, still nothing.
He took his bags and headed upstairs to the room above the garage that once was his, but had since become the rec room. His Stepdad told him that there was still a Murphy bed up there for him and since he was only going to be here for a couple weeks, that worked out fine.
When he opened the door, he saw the pool table, football table, a couple old eighties era upright video games and then the bed.
Walking over to it, he threw his stuff down next to it then went and looked out the window. All the cars were gone which sort of confirmed to him that he was alone, so he went back and opened his bag.
"I Should have enough time for a quick change into something else."
He released the catches and pulled the bed down, took off his shirt and pants and put them aside to wash later. He pulled out a pair of shorts and tee shirt and set them aside, stood up and stretched, then looked around. He saw himself in a mirror and flexed his muscles a little and did a pretty lame impression of Arnold.
"I'm am baaack! It's not a toooma!"
Suddenly, as he was about to turn around, he heard a scream and someone jumped on his back.
At first he was about to panic, thinking it was a burglar or something, but then he saw the reflection in the mirror and the face of his step-sister in the reflection.
As he tried to buck her off, his foot hit his bag he had thrown on the floor and he lost his footing and went down on the floor with his face planted in the carpet. He then rolled over onto his back and looked up at the little blonde who was looking down at him with a mischievous grin.
"Jeffy!" She yelled as she quickly climbed back on top of him, looking at his contorted face as he struggled to catch his breath.
"Misty, damnit, you about gave me a heart attack, you twit." He tried to get up, but for someone as little as she was, she had some strength and locked her knees and legs around his waist.
She started tickling him on the ribs and in the armpits, "College did not make you any less ticklish!"
He was squirming to try to get away from her and as he did so, he felt her butt sliding around on his lap. He felt his dick start to stir.
"Oh, please no..." he said to himself as he felt his erection continue to grow. He has not been with his girlfriend in over a month. The feeling of Misty's little ass bouncing around on his lap was too much for him, and the last thing he wanted was for his step-sister to be embarrassed by seeing that and think he was a pervert.
Just then she slid down and put her full weight on his lap before he could do anything to hide it, his dick was now extremely hard and very firmly wedged between the cheeks of her ass.
Her eyes opened wide and she looked down, then looked back at him and their eyes met. His face getting redder and her grin getting wider. Then she scooted further down so that the tent in his shorts was visible between her legs, "Jeffy!" she said in mock punishment.
She watched the tent for several seconds, but to Jeff it felt like an eternity. She giggled a couple of times as the tent bounced with the throbbing of his dick.
He struggled to get up again, "C'mon, Mist... I need to..."
She did not move, but shocked him back into silence when she started poking it, watching his dick respond by bouncing up higher.
She stared down at his tent, then laughed, "Look, it's a jock in a box...ers!"
Then, without warning, she scooted down a little and pulled the boxers down, freeing Jeff's dick, and watched it as it pointed straight up in the air, between them.
"Misty, please you are my sister.", Jeff said as he tried again to get away.
She was still staring at it, then ran her finger along the tip, then wrapped her finger and thumb around the glans and gave a little pull as she answered, "STEP sister."
She cooed as two little pearls of liquid seeped from the tip of his dick, "Nice!" She said, then scooped them off with her finger and put it in her mouth, slowly, making eye-contact with him as she did.
He shook his head, he was losing this fight, her blue eyes looking at him through the reddish-blonde hair, as she sucked his pre-cum off her finger, smiling at him.
Vainly he tried again, "But you're just a kid!"
She smiled then wrapped her hand around it and began slowly stroking it from the base to the tip, using a soft touch, the look on her face was like she was hypnotized by it. "I turned eighteen the week you left for college." She held her gaze with his, it was like she had him captivated by her stare alone..
He tried again, "I... I...oh god..." he closed his eyes as she leaned down and licked him like an ice cream cone, "I... don't want to take your virginity."
She laughed at this, then sat back up, looked down at his dick in her hand, she could feel it getting even harder, "Silly, I have not been a virgin since I was sixteen." She slid back further and then bent down and slowly took him all the way into her mouth.
Jeff gave in and stopped fighting, relaxing as she worked up and down on him, he could feel the head of his dick touching the back of her throat and then going a little further. The sensation was incredible.
He looked down at her and forced out, "My god... It feels like you have done this before." And without thinking about it he placed his hands on her head and started caressing her.
She mumbled, "Uh huh." She started using her teeth on him, almost a little too hard a couple of times, but she could tell he was not complaining.
With a single, half-hearted attempt to do the right thing, he said, "OK, I might ruin your dinner?"
Her response to that comment was to plunge herself all the way down on his dick and started licking his balls.
