Kate sat on the couch watching tv and scrolling on Instagram on her phone. It was 6 pm on a Friday night and she had nothing to do as normal. The sound of the door opening startled her causing her to look up from her phone. It was just her brother David just coming back from the gym. He walked in the living and dropped his gym bag.
“What did mom and dad leave for dinner?” asked David
“Just some mac and cheese” answered Kate
“Thanks, Beanie.” Snarked David
Her brother had given her that nickname because in middle school she wore a beanie every day to school, it was also because she was short compared to his 6ft frame as she only stood at 5’2.
Although she was shorter than most of the other girls in her junior class in high school, she managed to grab all the guys’ attention because of her busty 32D chest and her slim figure. Being on the cheer squad also helped grab the attention of many of the guys especially the football players. This has made the other girls on her squad jealous of her since all eyes were on her. She loved the attention she got from the boys. She would always flirt with all of them, even gave a few hand jobs or blow jobs but she never went any farther. Kate especially loved the attention she got from the male teachers all she needed to do for a better grade was flirt with them after class and a test score would go from a C to a B+. There were a few teachers who would try to push things further but to no avail, she wouldn’t break that easily.
Kate’s brother came back into the room eating the mac n’ cheese and chewing with his mouth open. He was a bit of a messy guy but he always claimed that he was that way because he was a bachelor in college and that when we found the right girl he would clean up his act. Kate knew the truth, he will always be a slob. He had a few girlfriends back in high school but they never lasted long. They were just flings here and there. He used to have a new girl on his arm every week but over the past few months, Kate noticed that he didn’t. Perhaps he had just matured by being in college.
“Mom and dad on one of their famous date nights?” asked David, sitting next to Kate and putting his food down on the coffee table that sat in their living room.
“You know it, string bean.” Kate jabbed getting back at him for his comment earlier.
Kate moved over farther away from her brother. “You can at least take a shower after you come back from the gym, you stink.”
“Is that any way to treat your only brother?” he joked as he hugged her in his sweaty clothes
She tried to break away from him, pretending to gag as she did it but her brother had always been stronger than her so there was one way how this was going to go but she wasn’t going to let him win easily. As the struggle went on David began to tickle her.
“Hey that’s not fair, you know I’m ticklish,” said Kate still struggling
“Fair or not it’s happening.” retorted her brother continuing his assault.
As he continued, his hand accidentally slipped up from her side to the side of her boob. Kate felt this but was distracted by her brother’s continuous tickling as she tried to twist and turn away. She twisted into her brother to catch her off guard inadvertently causing his hand to end up directly on her breast. He noticed that his sister’s breast was now in his hand. He continued his assault with one hand as he started to massage her breast with the other. He had groped his girlfriends in his past but his sister had the biggest boobs he had seen next to his mom who he could swear had an f cup or g cup breast. All he knew is they were big and all his friends considered her a milf. He had to admit to himself that he had a hot mom.
David started noticing his sister more a month ago when she forgot that he was home one day and left her door open to masturbate. He was on his way to the kitchen which took him past his sister’s room. When he passed he was going to ask if she wanted some food but the sight in her room caught him off guard. She was sitting in her bed naked masturbating and moaning the name of her high school crush Nick. He stood there for a good long second taking in her beautiful developed breast and perky nipples traveling his eyes across her body down to her spread legs which put her pussy on full view. She had one hand playing with a nipple and the other hand working her pussy. Her eyes were completely closed so she didn’t see him standing there. David felt his cock harden in his pants and he began to rub it from the outside of his pants but soon he couldn’t take it and slowly released his member from his pants and stood in the doorway as he masturbated to his sister. This only lasted a few minutes because she came squirting and soaking her bed with her fluids. Her eye’s remained closed as she did, giving her brother time to leave. He zipped his pants back up and continued on his set path and made a sandwich before heading back to his room to masturbate over the thought of his sister.
David squeezed Kate’s enormous breast causing a barely audible gasp, he stopped tickling her now. Kate was pinned into the couch nowhere to move with her brother on top of her. If this was a porno this would be incredibly hot she thought to herself. She was pretty sure her brother was also hard as a rock because something was poking her in her stomach. She wasn’t going to lie to herself, it was really turning her on. They stayed like that for about a minute before either one said something.
“Would you like a kiss too?” he joked leaning in toward his face toward his sisters.
“Never in a million years but when are you going to stop groping me bro?” she asked
“Oh shit sorry little sis I didn’t know,” he said embarrassed turning red as he removed his hand and got off of her and went back to his food.
Kate sat there confused for a moment. Was she just getting turned on from her brother’s hand on her breast? She questioned herself. She shook her head, no that couldn’t possibly be it. Who gets turned on from their sibling? He was good looking except for him being a slob. Her best friend Chloe had the hots for David when he was a senior and even tried to kiss him once at a pool party but he rejected her. Chloe soon got over him when she began dating one of the football players. Kate got up a second later shaking these thoughts out of her head. What was wrong with her?
“Now I need a bath. I have your gross smell all over me.”
“I happen to like my gross smell.”
Kate walked into the shared family bath. They had a small house with three bedrooms and one bathroom. She prepared herself a bath and her thoughts drifted back to her brother’s hand on her breast. Her hand drifted up to her breast without thinking and started to massage her boob. Her hand drifted down and starting to finger her pussy she was soaked. She started to think about her crush Nick from school.
Nick was the hottest guy in school. All the girls swooned for him whenever he entered a room. They did everything to try to get his attention from notes in his locker to wearing low cut tops that showed their cleavage and tight jeans that showed their asses. Kate found it funny what all these girls did but she also liked Nick and would do similar things. He was 17 but his birthday would be coming up soon and he would be 18. That just made him more attracted to her.
Her mind went back to what just happened between her and David. This time she allowed it to continue. Although he was a slob, he was hot. What would have happened if he kept his hand there? Was he really going to kiss her and would she have kissed him back? Would it end there? Her mind wandered to what she felt poking her in the stomach. Was that his cock? If it was it had to be at least 8 inches or more. These questions had to remain questions, he was her brother after all and that would be taboo. She was getting close to an orgasm. All of a sudden there was a knock on the door.
“Perhaps you really don’t want me to get cleaned see as you’ve been in there quite a while” the voice of her brother put a stop to her thoughts.
“I’ll get out before you start stinking up the house.”
She got out of the tub, grabbed her towel, and started to dry herself. All of a sudden it hit her that she forgot her sleepwear in her bedroom. She quickly wrapped her towel around her and walked out of the bathroom. Her brother was standing there waiting for her to get out.
“Hey about before it was nothing.”
“Don’t worry perv, I’m not telling mom or dad.”
“Good, let’s rent a movie to watch tonight.”
“As long as you clean yourself good, mister. Your stench might kill me”
She turned to walk into her bedroom. Her brother usually took quick 10 minute showers. That didn’t give her much time to finish what she started. She would have to finish later when she went to bed. It did give her time to throw on her nighty. It was big enough to hide her breast and her figure but it was short enough on her that if she bent over it showed the bottom of her butt. That’s all she wore for bed, with nothing underneath. She found bras and underwear uncomfortable to sleep in.
David got undressed and stepped into the shower. He was only half-mast after getting a hand full of his sister’s beautiful breast. He started thinking about how a month ago he caught her and watched her masturbate. Was he really thinking of his sister in that way? Did he cross a line with her by just groping her? Would she be mad at him? He grabbed his hardened cock and began to stroke it. He tried to think of anything else, a girl from school, his favorite professor, the girl from the gym today who seemed interested in him but to no avail, he kept finding his thoughts going back to Kate, his sister. What is wrong with me? He thought before stopping and turning off the shower. He grabbed his boxers and put them on. He usually walked around half-naked when their parents weren’t around. It was something normal for him. He stepped out of the bathroom.
After she got dressed and grabbed her movie watching blanket from her bed she went to the living room and began to go through the list of movies on demand. She thought about choosing the romantic comedy movie perhaps if she put on a chick flick that her brother would leave and give her the alone time she now desperately needed.
“A chick flick? Trying to test how long I’ll last?” Her brother just walked into the room with nothing but boxers on. Showing off his evenly toned body and six-pack. The outline of his cock could be seen through his boxers. Kate couldn’t help but stare, it was massive. She licked her lips.
“Hey, earth to Kate” her brother tried to get her attention “Now who’s the pervert?”
“Still you.”
“I’m going to make the popcorn, don’t start the movie without me.”
They would normally cuddle or sit next to each other while watching a movie. This Friday they sat with a sizable gap between the both of them. The tension created earlier still hung in the air. To lighten the mood they tossed popcorn at each other and laughed at how horrible a movie it was. This went on for a while until the scene changed from a make-out scene to a full sex scene.
“You might be to young for this part Beanie” David moved toward the remote on the table
“Me too young talk for yourself” Completely forgetting what she had on, Kate lunged at his hand trying to grab the remote first. Her hand successfully knocked her brother’s hand away but accidentally paused the movie on a picture of the woman taking her bra off as the man laid in bed.
Kate landed across her brother’s knee, one hand on the remote and the other just above the waistband of her brother’s boxers. The blanket was left behind in the mad dash to stop her brother. Her breast dangled just next to his leg, almost grazing them if she moved too much. Even worse for her is that her nighty got pulled up and now half her ass was on for viewing pleasure. Kate didn’t notice any of this as she tried to press play but the remote wouldn’t work.
“It won’t work”
“Give it here.”
Kate handed him the remote and tried to return to her seat. As she tried to get up but doing so her hand grazed lower on her brother to where it was now directly on his dick. Her breast grazed against his legs. She looked over to what her hand was groping. Seeing where her hand landed. Seeing her brother was busy with the remote she decided to rub it gently. What was she doing? He was her brother? But she didn’t care, she was horny from not being able to finish early and the picture that was now stuck on the screen didn’t help much. She continued. Her brother felt larger than when he was on top of her early. It was like her hands were moving on their own.
David felt her hand slip down onto his cock. He thought she would immediately move it due to her reaction early besides they were brother and sister. Instead, she started moving her hand up and down making his cock harder. He pretended to continue to look at the remote. After a minute of this, he looked down at her. She was so preoccupied rubbing him that he was able to slip a hand on her bare ass.
Kate felt a hand on her ass. She glanced up at her brother who stopped looking at the remote but was now looking at her while he groped her ass.
“You really are the perverted.”
“So are you bro. Can you stop groping my ass and at least help me up?”
He removed his hand from her ass and grabbed her by the waist. He pulled her back up onto the couch but he didn’t stop there. David leaned into his sister and instead of stopping this time he gave her a full kiss on the mouth. Kate backed away. Did he just kiss her? And more importantly, Did she just enjoy it?
“What do you think you are doing? We are brother and sister you can’t do that” she said in shock
“You were just playing with my dick.”
“I wasn’t” Kate got all flustered. “Can you fix the remote?”
“Yeah give me a second.”
David took the batteries out and placed them back in. A second later the movie was playing again.
“You know it is more common than you think for brothers and sisters to do that type of stuff”
“Are you saying you are attracted to me, David?” she laughed
“You are very attractive for your age, I’m sure you get tons of guys trying to score with you”
“There have been many and I’ve turned them all down. I like older guys but they still see me as a kid”
“Clearly you are not.” her brother said as he undressed her with his eyes
“You probably have many women looking at you with those muscles,” she said, starting to feel awkward.
“A lot, yes.” David flexed
Kate started to undress him with her eyes.
David went for a dive and asked “You’re still a virgin aren’t you sis?”
“Yes. What about you bro?”
“Not anymore.”
“Wait, What? Do tell!”
“It was with my English teacher last semester at college.”
“Was it good?”
“It was amazing”
Kate noticed his cock was straining against his boxers. She couldn’t ignore what she was feeling even though it was her own brother. Without thinking she leaned back and planted a kiss on her brother. He grabbed her cheek and returned the kiss. They embraced like this for a few minutes but for them, it felt like hours. When they broke the kiss they looked at each other differently.
“Wow, Kate that was a great kiss”
“Bro…” was all she could manage before he kissed her again, this time slipping his tongue inside of her mouth. As their tongues started to dance Kate started moving her hands around her brothers back and he did the same. He felt her clothed breast on his bare chest which made him kiss her harder. When they broke the kiss again.
“This is wrong.”
“If this is wrong then I don’t want to be right.” David tried to kiss his sister again but Kate pushed him away.
“We are brother and sister. It’s incest.”
“I won’t tell if you don’t. How about only kissing? We’ve already crossed that line” Her brother asked
“Only kissing.” She leaned into him again as he leaned back ending up with Kate on top of her brother kissing him. She could differently feel his cock again poking her. Kate climbed on top of her brother…
