Kevin and Dawn
Part-1
Although Kevin and Dawn were step-kids, they coincidentally shared the same birthday, and had grown up with the same closeness as if they were actual twins.
After each had independently discovered the glories of masturbation, they secretly began trying to get glimpses of the other sibling naked.
Dawn was the first to figure out that her brother was sneaking peeks at her, and it gave her a little thrill to know that he found her sexy. As a result, she began giving him more opportunities to see her body, like having her bikini top "accidentally" untie in the pool, and "absentmindedly" leaving her bedroom door half open while she was getting dressed.
His bedroom was at the other end of a short hallway from her brother's, and as she would stand in front of the opening getting dressed or undressed, she imagined him in the dark in his room stroking his boner at the sight of her nakedness. Her little teasing game never failed to make her wet. At the time, she didn't even know that being an exhibitionist was a thing.
One day, when they were home alone, she decided to take her tease to the next level. She knew that Kevin was in his room—pretending to play video games—and that he was most likely watching her through his own partially-open door.
She gave him a good long show of her nakedness, which included her standing and facing him with her tits and pussy fully exposed to his gaze while she had her head thrown back brushing her long hair. She then turned around, and bent over at the waist to brush it the other way. The result—the purpose, actually—was that she was giving him a prefect view of her compact, naked ass.
As she stroked her hair from her neck up and over her hanging head, she moved her legs slightly apart as if to keep her balance, and she wondered if he could see the wetness that her show was producing at her pussy lips. She imagined that he could, and she also imagined him with his pants around his ankles and stroking his hard-on because of it.
The thought of him jerking off while staring at her glistening pussy turned her on so much that, still bent over with her naked ass facing directly at her brother, she reached up between her legs and slid her fingers through her pussy lips. She had never touched herself while showing off for her brother before, and the added nastiness of it sent a spectacular thrill through her body.
She rubbed and squeezed her slick pussy lips, smearing the wetness all around, and then she crooked her middle finger and pushed it up inside her cunt-hole.
She spread her legs farther apart and pushed the digit in as deep as she could while grinding her fist around against her pussy. She then began sliding the finger in and out, quickly picking up speed and making sloshy wet sounds as she finger-fucked her cunt in—hopefully—full view of her brother. She wondered if he could hear the wet slapping of her fist against her sopping pussy. Imagining that he could, she slapped even harder.
The effect of openly finger-fucking her cunt while her bother "secretly" watched, and of the forceful smacks she was giving her wet pussy had her cunt on fire.
Needing more than her finger could provide, she took the hairbrush—which she had used as a dildo many times—and in one slow push inserted its fat handle up her cunt. Then, with her other hand on her bed to steady herself, and with her head hanging down and her eyes closed, she began fucking her cunt. All the while she was envisioning Kevin beating his stiff cock furiously at her sexy show, and it turned her on like never before!
Lost in the reverie of the thick-handled hairbrush sliding in and out of her cunt and the image of her brother pounding his dick while he watched her fucking herself, she never even noticed when he walked into her room, completely naked, and sporting the stiffest hard-on he had probably ever had.
It startled her when he grabbed her around the waist, and she yelped a small, "
Oh!
" as he lifted her off her feet, flipped her over, and landed her on her bed on her back.
In the quick motion the hairbrush became disengaged from her cunt, but almost as soon as she was on her back, Kevin had her legs pushed wide apart, and had his face planted in her wet pussy. As he ground his mouth against the soft, soaking wet folds of flesh, and snaked his tongue up and down through her slit, she let out another "
Ohhh!
" and put her hands on the back of his head to force him even tighter against her pussy.
"Oh, fuck, Kev!" she moaned as his tongue wormed its way as far inside her as he could force it. "Oh, yeah! Do it, bro! Eat my pussy! Shove your tongue up my little cunt-hole!"
When he had thrown off all of his clothes and headed for his sister's room with the single thought of eating the juicy cunt that she was obviously teasing him with, he wasn't sure what her reaction was going to be. But he didn't care, either. If she was going to tease him like that, what did she expect was going to happen?
Encouraged by her positive reaction and the fact that she was now holding her own legs spread far apart, he stuck out his tongue and began bobbing his head, giving her a tongue-fuck and mashing his face into the sloppy wet folds of her pussy with each bob.
She wound her fingers into his hair and began beating his face into her pussy, masturbating with her brother's face and tongue.
As she felt her orgasm quickly building, she said, "Stick your finger in me, Kev! Finger-fuck my hot little cunt! Shit, you're gonna make me cum, bro!"
As he pushed his finger up her wet cunt-hole, she pulled his face upward, and told him, "Suck on my clit! Wiggle your tongue on it and suck at the same time!"
He eagerly complied, and as he found the protruding little nub that he had only ever seen in Internet porn, she moaned, and said, "Oh, yeah! Right there! Oh, fuck, bro!"
Sucking her clit and hammering his finger up her sopping wet cunt-hole had her racing toward her orgasm, but she wanted more. She found the hairbrush on the bed, and pushed it between her legs and against Kevin's flying fist.
"Fuck me with this, Kev!" she told him, "Fuck my cunt and make me cum! Make me cum all over your face!"
Kevin began ramming the fat handle up his sister's cunt while continuing to lap and suck on her clit, and he could hear and taste the wetness of her pussy building quickly. He sped up his strokes of the hairbrush in and out of her pussy, just like he always sped up his own strokes when he jerked off and was right on the edge of cumming.
Suddenly, she let out a high-pitched squeal, and her cunt gushed a small river of cum into his mouth and all over his hand.
He continued sucking and fucking, and her cunt continued to pump wave after wave of salty pussy juice into his face.
Finally, she pushed his face away from her pussy, and the hairbrush from her cunt, and after a few long breath-catching pants, she said, "That was fucking awesome!" As she sat up on the bed she lifted his head up, and then she kissed him hard, savoring the taste of her own cunt juice that soaked his face. When she broke the kiss, she added, "Now it's my turn!"
She stood up, lifting him to his feet at the same time, and then dropped to her knees in front of him.
His rock-hard cock, drooling pre-cum, stood straight out in front of her face, and she opened her lips, leaned forward, and took the glistening head into her mouth. She sucked lightly, and swirled her tongue all over the spongy knob.
She had always imagined that when a guy's dick got hard, the entire thing would be stiff, so the squishy texture of her brother's cock-head came as a surprise, but she liked it. She sucked on it harder, playfully getting it to squish and deform in her mouth, and she even tried to poke her tongue into the tiny pee-hole.
Being the first cock she ever had in her mouth, the taste was a new—and pleasant—experience, too. The slight saltiness of his pre-cum mixed with the muskiness of his sweat to produce a sensation that was amazingly arousing all by itself.
"Oh, fuck, sis!" Kevin moaned as he looked down at his sister's pretty lips encircling his boner—an image that was a hundred times better in reality than any of the images he had conjured up in his head while jerking off.
Dawn pulled back, and let the head of her brother's cock escape her lips with a slight
pop!
She looked up at him, and with a smile, she said, "Do you like that?"
"Oh, fuck, yeah!" she said. "Keep doing it, sis! Please!"
"Doing what?" she asked.
"What?" he replied. How could she not know what he meant?
"Tell me what you want me to do, big brother," she said with an impish grin. "Tell me what you want me to do with the fat, hard cock you have sticking in my face. Talk dirty to me, bro. That kinda turns me on."
"I ... I want you to give me a blowjob, sis!" he said. "Please?"
She gave his fat cock-head another suck, and then with a wicked-but-sexy curl to her lips, she said," Don't ask me, big brother;
tell
me!"
He finally got that she wanted him to be
nasty
to her, and although it surprised him, it turned him on even more.
He wound his fingers into the hair at the back of her head, and took his raging boner in his other fist. Holding her head still, he pumped his cock in front of her face to get a good drop of pre-cum to ooze out of the pee-hole.
As her brother jerked his cock with one hand, he tightened his grip in Dawn's hair with the other. But instead of hurting, the pain of her hair being pulled was surprisingly arousing to her. She held her mouth wide open, waiting for him to push his dick into it and to tell her what he wanted her to do to it.
But instead, he commanded her, "Close your mouth!" She did, and then he wiped the drooling, spongy dick-head across her lips, over her nose, and up and down both of her cheeks.
Finally, he pressed it against her lips, and growled, "Now open up and suck on my fat dick, you little cock-tease!"
She had barely relaxed her lips, when he drove his dick into her mouth all the way to the back of her throat, and the sudden jab at her gag reflex made her convulse slightly. He stopped pushing, but he didn't pull his prick back out, either. Instead, he held his cock-head just a fraction of an inch off his sister's limit, and almost snarled at her, "Oh, fuck, yeah, little tease! You look fucking hot with my stiff cock shoved in your mouth! Now suck on it! Give your big brother a fucking blowjob!"
As she eagerly sucked and pushed her tongue around the fat cock filling her mouth, he tightened the grip of his fingers snarled in her hair and he started bobbing her head back and forth. At the same time he wrapped his other fingers around the still-exposed portion of his dick, and began jerking off, slapping her lips with each pull of her head onto his cock.
As he bobbed her sucking mouth up and down his dick, he taunted her, "What a nasty little sis I have! Fucking your own cunt with a hairbrush for me to watch, letting me eat your dripping pussy, and now giving my big stiff boner a blowjob!"
