In the last few weeks Chris's sister Anis, had changed completely. Turning from the average church going, flute playing marching band nerd, into a Goth on her eighteenth birthday, acting strange and mysterious. Going out at all hours of the night and sleeping mostly during the day. Soon changing her jeans and T-shirt look into something darker and sluttier. Chris her older brother seemed to be the only one that noticed these changes, starting to see his sister not as his little sister but as something very hot and lusting after.
Anis had been a very pretty girl all her life, small but curvy and overdeveloped for her age with very pale skin, long black hair and ice blue eyes. While in her mid teens she had very nice orange sized tits, it seemed almost overnight when she turned eighteen that her breasts had grown to melons at a 30C cup.
Anis soon started teasing Chris by sitting on his lap when their parents were not looking, wearing very short black skirts, low-cut tops, and latex. Her teasing drove him nuts as she could always feel his cock grow hard when she sat on his lap, then rub and grind her tight ass onto his lap.
Chris knew it was wrong to think of his little sister that way but he would jerk off over her almost every day. And it didn't help that Anis was steadily getting bolder and bolder, driving him crazy with her teasing.
Every time he got horny he would start to jerk off thinking of something else but his sister would always come back into his mind. He began blowing the most giant loads thinking of playing with her young hot little body, his lust driving him nuts as he started to lose any logic or reason.
Chris found that he got horny more often, that he was hard a lot of the time and could cum a lot more. He always ended up thinking of his little sister, having strange twisted dreams of her every night. And just when he thought he was starting to go crazy, their parents suddenly and mysteriously decided to go away for a long weekend, leaving them alone in the house together.
Chris waved goodbye to his mom and dad reluctantly, wondering just what was going on with him and how he was going to handle a weekend with his little sister all alone, as mom and dad pulled away on the driveway. Chris stood there waving to them wearing a polo shirt, T-shirt, jeans, boxers, and sneakers.
That day Anis stayed in bed until the afternoon, well after their parents had left. After she got up she began to wander around the house wearing just a black band T-shirt the band Tool's logo across her chest. The shirt big on her but not quite long enough to cover her black satin thong, also showing off her incredibly pale thighs completely. The shirt thin enough that Chris could see her overdeveloped young tits bouncing underneath. She seemed to ignore him at first apparently not surprised her parents had left.
Chris's eyes locked onto her young hot body when Anis finally came downstairs. Trying to play a video game to keep his mind off of how horny he was but got a raging hard on when he watched her walk around the room with her young huge tits bouncing in her little shirt.
After Anis had some breakfast, seeing Chris playing video games, she walked into the living room and stood between him and the TV, intentionally blocking his view, giggling. As Chris looked up he see that even though Anis was not dressed she had on heavy makeup, eyeliner, and black lipstick.
"Uhhh Sis," Chris said. His eyes wandered up and down her hot young little body as his cock began to throb. "What are you doing? You're blocking the TV!"
Anis just giggled at him wickedly. Acting like she was just doing it to piss him off like the bratty little sister she is, but there was a strange glow in her eyes.
"Wouldn't you rather look at me than the stupid TV?" She asked.
At first Chris was annoyed but the glow in her eyes basked over him and he slowly nodded his head up and down like in a trance, and said, "Yes little sister, I would rather look at you than the stupid TV."
As if satisfied with his reaction, Anis shuffled toward him slowly across the carpet and then kneeled right in front of him, still smiling mischievously. Anis was close enough to him that her tits rubbed against his knees slightly through the shirt.
"Well now you can see over me...are you going to keep playing your stupid game?" Anis asked him.
Chris's eyes went wide staring at his hot little sister kneel before him, his knees electric rubbing against her perky firm tits as his cock throbbed and twitched in his jeans. He could feel it leaking precum onto his boxers.
"Well I don't have to play my stupid game, what do you want to do Anis?" He asked.
Anis's eyes seemed to become larger as she stared up at him from her kneeling position, pressing her tits against his knees heavily Chris could feel just how soft they were.
"I just want to talk to my big brother...isn't talking to your sister more important than playing games?"
"Yes little sister," Chris responded by holding the power button on the controller, then throwing it off to the side of the couch.
When he tossed the controller aside, Anis hopped up suddenly onto his lap in one fluid movement, her eyes somehow staying locked onto his, not allowing him to look away. Chris could feel her bare thighs wrapped around him, seeming to trap him, her tits almost pressed against his chest, the smooth satin of her panties rubbing slightly against his stomach, her soft ass against his crotch.
"What would you like to talk about Sis?" He asked with a gulp.
"I heard some strange noises coming from your room last night...were you having a nightmare? What were you dreaming about?" Anis asked giggling.
"Uhhh ohhh god," Chris moaned out softly trying to get away but he couldn't as his cock throbbed and twitched even harder in his pants as she straddled him, her giant tits rubbing against his chest as he felt trapped underneath her. "I don't want to say Sis, I was thinking about you! Dreaming about you!"
Anis leaned forward a little, Chris felt like he couldn't see anything other than her eyes. They seem to have become darker and it made the room seem darker, her body soft and strangely cold against his.
"Dreaming about your little sister? What kind of dream would that be? Tell me, big brother," she commanded.
"Ohhh gosh, I was...dreaming about...you...and me...and we were...ummm...we..were...fucking! I dreamed about fucking my little sister okay! I can't get you out of my mind!" Chris said almost moaning out, as his body seemed to melt into the couch underneath him.
Anis face closer and closer to his, her body pressed tight against him as she said, "Is that so? Why can't you stop thinking about me? Am I so special?"
"I don't know Sis! You just are always in my mind! I can't stop thinking about you! You're always teasing me when mom and dad aren't looking or around! Showing me that hot little body or jumping up and grinding all over me!"
"So you think I'm hot? You're thinking about your little sister's body all the time? Is it that good?" She asked smiling a little, their noses almost touching, her eyes swallowing him.
"Oh yes so very fucking hot little sister! You're the only chick I think of anymore! You're all I jerk off to! I can't stop thinking about your hot little body!"
