Trained Step Sister pt.2

First, let me apologize for taking so long to revisit this story. I really struggled with certain aspects of it, and had to set it aside to finish the Chris and Christie series. After some time away, I think that I’ve come back with a better handle on the characters involved.

Last we left off, Allison has started acting in a very possessive way towards Mark, after several weeks of pretending to be an unwilling participant in their sexual acts.

Mark awakened the next morning to Allison’s mouth on his cock. He looked down at her in shock. She had never initiated sexual contact between the two of them previously; this was a whole new thing.
She looked up to see him staring down at her incredulously and gave she him a sultry stare as she pushed herself up on all fours and really started getting into it. She was naked and swinging her hips around in a slow circle while she pumped her arms up and down, swallowing his cock on each downstroke.
Holy shit. Mark thought. She is one sexy bitch.
He was mesmerized by the sight of her heart shaped ass tracing a hypnotic pattern through the air.
Allison grinned; she knew that she had him exactly where she wanted him. As he clenched his teeth and dropped his head back on his pillow, she let his cock drop free from her mouth, hopped off the bed, and sauntered out of the room.
What the fuck????? Mark thought in frustration. Then it dawned on him, Allison was back to her old tricks, trying to provoke him. He calmed himself down, trying to get his erection to go away, but he knew that it was no use.
He hopped up and pulled on some underwear before heading to the kitchen. Allison was there, stark naked, finishing her breakfast.
“What took you so long? Your food got cold.” She went to the counter and grabbed his plate, bringing it towards the table when she dropped it. The plate broke on the floor, leaving a mess of bacon and eggs splattered across the kitchen.
“Oopps.” She said with a mischievous smile. “And that was the last of the food. Looks like you go hungry.”
Mark stared at her impassively. “You better clean that up.”
“Why? It was your food.”
“Then it’ll stay there.” He replied, and went to the pantry, finding some Pop-Tarts.
Allison pouted at his back. He wasn’t playing along, this wasn’t fun.
As Mark busied himself at the pantry, he grinned to himself. Alison was going to have to do a lot better than that. At least she wasn’t trying to kiss him, or do any girlfriend-type stuff. That had seriously freaked him out. As he turned back around, he was treated to quite a sight: Allison was down on all floors, cleaning up the mess she had made with her ass saucily tilted towards him, displaying her pussy and her asshole. As she worked on the floor, she made sure to accentuate her movements so that he couldn’t help but be drawn to her.
Mark steeled himself and exited the kitchen, finishing his food.
Allison heard him leave, and gritted her teeth in frustration.
What the hell was he doing? She had left him with a huge boner, she could still see it when he came into the kitchen! She decided that some direct action was necessary.
When she finished cleaning up the mess, she headed to his bedroom. He was in the shower, with his work clothes laid out on the bed. She smiled and reached down between her legs and started playing with herself.

When Mark hopped out of the shower, he checked his watch. Running a little bit late, shit. He hurriedly finished brushing his teeth and headed out to his bedroom, where he grabbed his clothes and pulled them on before heading out the door. As he was driving to work, he noticed something odd.
What the hell was that smell? It was … him???? No, his shirt. He grabbed it and pulled it up towards his nose and took a deep whiff. What the hell? It smelled like … he could recognize Allison’s body lotion, and … pussy?
Holy shit. What did she do?????
He grabbed his phone and called her.
“Yes???” She was asking for it for sure, that little innocent tone, hinting at a bit of naughtiness.
“Allison, is there something wrong with our washing machine? My clothes smell funny.”
She giggled on the other end of the line. “Check your camera.” And she hung up.
Mark scrolled through his phone and pulled up his camera feature. Sure enough, there was a new video, shot that morning.
As Mark pressed play, he almost swerved into oncoming traffic.
On the screen was a bald pussy. A pair of fingers came into view, and began dipping into the pussy, spreading its’ juices all along the outer lips. Then a white shirt appeared on the screen, and was rubbed along the pussy. After about 30 seconds, the angle changed, and he could see Allison’s face on the screen.
“Think of me at work today.” She said, and blew a kiss at the screen.
Mark gritted his teeth and sped along the road, his mind racing.
As soon as he got to work, he raced into the employee’s entrance and checked in just in the nick of time. He was positive that everyone could smell what was on him, but no one seemed to notice anything. The only problem was, Mark could still smell it, and it was getting him aroused.
As he walked to his post, he surprised by Julia walking up behind him and wrapping her arms around him.
“Hey!” She exclaimed. “I wanted to say thanks for taking me out last night.” She told him. An odd look crossed her face, and Mark panicked. Oh shit, she can smell Allison.
“Yeah, I had a really good time, thanks for going out with me.”
She didn’t seem to be paying any attention to what he was saying, but was instead peering at him, her face locked in a mask of concentration.
“Hang on.” Mark said. He ran to one of the kiddie pools and whipped his shirt off, dipping it into the water and wringing it out. He returned to Julia, pulling the wet shirt back on.
“Sorry about that. My step sister sprayed me with her perfume on my way out the door, that smell has been driving me nuts.”
Julia smiled at him. “I thought you smelled a little different.” She eyed Mark’s lean body through the wet shirt. “So I guess we should have a wet t-shirt contest for the guys. A little equal opportunity eye candy, hmmm?” She raised an eyebrow at him, and Mark grinned. Maybe Julia really could offer him a way out of his mess with Allison.
“Want to do something after work?” He asked her.
“I’d like that.” She replied. “See you then.”
Mark spent the rest of the day with a grin on his face. So he had a date with Julia after work, then home to give Allison a good fucking. The best of both worlds.
Since it was the Fourth, the water park closed early and there was a fireworks show. Julia decided that she wanted to hang around and see it, and Mark was agreeable to that idea.
As the show wound down and everyone headed to the exits, Mark took Julia by the hand and led her to the staff locker rooms.
“So what are we doing in here?” She questioned him, leaning up against the door frame and folding her arms across her chest.
“I just need to grab my stuff. Did you want to grab something to eat?”
She grinned at him. “Oh, so you didn’t have any nasty intentions by bringing me in here?”
“Disappointed?” Mark countered.
She smiled and looked down as Mark walked towards her.
“Maybe.” She smiled demurely.
Mark looked her up and down. She was smaller than Allison, and where Allison was a blue eyed blonde, Julia was a Eurasian beauty, half-Thai, and half-Caucasian. Her Thai heritage could be seen in her facial features, dark complexion, and her tiny frame, which sported large boobs that were almost oversized for her small body.
He put his arm around her waist and pulled him towards her, bending down and planting a firm kiss on her lips. She moaned and melted into him, running her slender hands up and down his lean back. One of her hands dipped down to cup his ass, and she pulled him tightly against her, rocking her hips against his leg. His cock was trapped between their bodies, pressed against her stomach. There was no way she could miss his growing erection. She wiggled against him, causing his cock to twitch and she broke off their kiss, laughing.
“Now about that food you promised me.” She said, looking mischievously at him while she lightly ran her fingernails along his shorts, tracing the outline of his cock.
“Let’s go.” He said, and took her by the hand to his car.
