Admittedly pansexual and built like a boy she was gender fluid and vacillated between wanting to be more like her Mom and also hoping to stay flat chested forever. She had secretly bought an electrolysis hair remover last year and was permanently removing any new body hair that grew.
Her lips still tingled from the last kiss she had given her brother. She could feel her pulse in her tiny clit and her panties were growing damp. She suspected that her brother had been jacking off or about to by the way he kept his lower body out of view. Slipping her hand down the front of her shorts, she parted her sticky lips and began to furiously rub her swelling clit in small circular motions.
With her other hand, she lightly pinched her hyper sensitive nipples through her shirt. She knew she could cum just from touching herself on the chest but was in a sudden rush to get the edge off. Maybe if she went quietly back she could peek under David’s door and watch him beat off.
Using the card his mother gave them for just such things, David ordered the same thing that they had last time. ETA 45 min said the app. So he went back to his porn tab and pulled his aching member out. It seemed longer than usual and both his hands would not quite cover it now. “No wonder” he thought to himself, “I have had a growth spurt”. He turned slightly so he could use the mouse and masturbate with the other hand.
David, had no idea that Julie was just now laying on the floor in the hall, she had a clear view of him from the chest down and watched him move the skin on his uncut cock.
David found a brother-sister vid and put his head phones on and began fantasizing that it was he and Julie in the film. When Julie saw him get the headphones she had a naughty idea and after waiting till her brother was completely engrossed, she slowly and silently opened the door.
The blonde girl on the screen was not as pretty as his sister but was thin and flat chested. She fitted his fantasy perfectly.
Crawling like a cat after its prey, Julie crept closer to her brother, his pants down around his thin legs but a surprisingly long cock in his hands. She heard him say her name under his breath which gave her a thrill that felt like it ran from her lips to her clit like hot water.
She could now see the title of the film he was watching and knew he was getting close, his hand almost a blur.
David felt his orgasm coming, closed his eyes tight and squeezed the base of his overheated penis. He was imagining his sister’s mouth on it and, for a moment, it felt so real!
With a crashing shock reality kicked in. At first he was so confused he could not move! His little sister had stuffed as much of him into her mouth that she could and was sucking hard and swallowing fast.
“JULIE!!!??” he shouted, “Stop that!” but there was little conviction in his voice.
Julie, for her part, was orgasming as she drank down her brother salty seed, wrapping her soft little hand around his almost hairless ball sack she sucked for all she was worth.
David was shouting at first but then convulsing as his cock was being milked. He put trembling hands in her short hair trying not to jam his dick down her throat. Julie’s body was also being wracked with spasms as some of the slippery sperm leaked out of her mouth down her chin.
The young girl pulled her head off his lap and lay on her back, licking her face and using her fingers to scoop any errant fluids into her mouth, beatific smile on her face. Both teens were panting for breath.
“Damn that was hot, Dave!” Julie said still smiling and enjoying the small aftershocks of her orgasm.
“What made you do that?” her brother asked, “Not that I’m mad, I’m just in shock.”
With a grin she said “I have wanted to for a few years now, have you not seen me looking at you when we swim or when you get out of the shower?”
“I have,” he confessed,”but I chalked it up to overactive hormones. I was busy looking when your bikini goes up your butt like a thong, or down your shirt when you bend over.”
“Oh! you should have just asked!”she said with a twinkle in her eye. His little sister pulled her shirt up and over her head tossing it by the door.
“Look all you want big brother anytime you want.”
David gazed down with a hunger at her flat chest and bright pink areolae – her tiny nipples stiff like pencil erasers. Holding her hands together over her head, she stretched like a cat, arching her back off the floor. Not accidentally pulling the crotch of her shorts tight to meet mound showing a little camel toe. Her older brother’s eyes were drawn to this phenomenon.
“Jules, do you not have any panties on?”
“Why don’t you put your hand down the and find out?” She said batting her eyes and grinning.
With his pants still around his ankles the teenage boy got on his knees unable to resist. His hand over her diamond hard nipple caused her to draw in a breath and close her eyes.
Slowly he slid his hand down her flat stomach while leaning his face toward her frail chest. His fingers crept under her light cotton shorts and over her smooth hairless mound, his mouth came near her left nipple.
Julie moaned and flexed her hips up to push his fingers into her moist slit as she pulled his face to her breast.
David clamped his mouth on her nipple and began suckling, that ingrained human nursing rhythm that we all have. Jules gently guided his hand and showed him the method she liked for rubbing her clit. This never-before-felt stimulation was like a rocket! Her orgasm came crashing like a wave, arching her back and clamping her hand down over his, covering her brothers hand.
At last it was too much and she breathlessly said “Stop, stop, it’s too muuuuch.” Drawing the last word out like it had 4 syllables. David tried to sit back in his heels but fell over in the tangle of his pants and laughed at himself.
Sitting up Julie leaned over her brother “We should have done this years ago.” After a pause she bent down and kissed him open mouthed, both hesitating for a moment but then with passion.
Clumsy tonguing back and forth with some giggles, a knock at the door broke them up.
“Oh shit, it’s the pizza!” David said in a mild panic while scrambling to get his pants untangled.
“I got it” said Julie, she jumped up and darted out of her brothers room.
“Coming!” She called on her way to the door yanking it open to reveal herself in all her topless glory to the young man from the pizza place. He gawked with open mouth amazement at the half naked nymphet before him.
Calmly taking the boxes from his unresisting hands she politely thanked him. Holding out her other hand to him he shook it out of reflex. “Fuck!” the young man said.
Frowning Julie asked “Do you kiss your mother with that mouth?”
“N-no!” he stuttered.
Julie gave him an impish smile and kissed him lightly on the mouth.
“Maybe you should?” she remarked, as she closed and locked the door.
Mark stood on the porch and then rubbed his hand where the sexy little girl had kissed him.
“Maybe she is right?” he said to himself his lips tingled and he faintly smelled roses. On the way back to the car he thought of how sexy his mother really was, he had to admit to himself that it’s why he was attracted to BBW girls.
