John Kellerman: Sisters in heat

The bikini top was stretched up now, exposing her other tit. Steve kissed her tits eagerly, awkwardly, hurrying. Robin's mind convulsed with fear as his lips closed over the tender swell of her tit, as his tongue raked the pink nipple.

"Steve… let me up. Right now!"

She tried to slide her legs out from under him. But his tongue brought a wave of amber heat to her senses. Her pulsing cunt flooded over with steamy juice, wetting the crotch of her panties thoroughly. She could feel the swelling lips rub against her panties, could feel the subtle, teasing friction over her clit.

It was like the time she'd masturbated in class by crossing her legs tightly and kicking one foot up and down. No one had known a thing. In civics class, the most boring subject in school.

Steve's lips pulled her titty flesh deep into his mouth, his hand was working down the hard, flat of her belly now, searching at the edge of her jean shorts, then slipped under. The most sex Robin had ever had was after the high school dance the year before. Harry Hagstrom had taken her into an empty darkened classroom and put his hand under her pink dress. She'd been scared, but curious. She'd let him kiss her, let him rub lightly along the damp, slick crevice of her cunt until she couldn't take any more. Her knees had trembled that night and she'd clung to the boy's shoulders as he grunted with eager surprise at her heat and at the pungent, sweet aroma that coated his fingers when he pulled them from her silk underwear.

And Stevie's fingers were closer to the pulsing lips of her pussy.

"Ohhhh… Steve what are you doing?"

"I love you Robin… Jesus… I…"

"Nooooo… Uuuuhhhhh!" The breath rushed from her lungs as the buttons came open and the faded denims peeled back.

Steve's hand was shaking. He fondled the plump, hot softness of her pubes through sheer silk, moaning against her tit as he tried to find her nipple again with his tongue.

Weakly Robin pulled at his hair, but she seemed to have no strength left. Her muscles wouldn't react.

Steve was pushing her cut-off jeans down her slender thighs now. He was doing it without her help. She didn't want to help. She didn't want… This was her brother!

"No. We have to s-s-stop… Oh Stevie, Stevie!"

Robin's head fell back as her small tit was sucked deep into her brother's mouth again. This time he bit down on the nipple, rolled it between his teeth. Her back arched upwards from the sharp, frenzied sensation and her jeans fell past her knees, dangled around one ankle. Somehow Steve had worked his body between her thighs. He was on top of her, the towel bunched between their bodies.

"Steve… Steve… I don't want you to… Oh! Ohhhh!" It was the feel of his bare chest rubbing against her tits that started her babbling.

Her tiny bikini top was tangled loosely around her neck now. She was exposed, naked except for the skimpy satin underwear.

Stevie felt so hot against her. She couldn't resist the instinct to hug him, to hold him. Their tongues lathed together. She moaned into his mouth. She'd never kissed like this, didn't really know how. Stevie was showing her, his hands making her skin bum with tingling waves of delight. And then she felt him push the soppy crotchpiece of silk to one side, felt a finger divide the puffed lips of her pussy. Again Robin arched her back.

"Stevie… that's enough… you're scaring me!"

She rolled her body as if to escape. The towel was being pulled away from his loins. The bulge of his cock gouged along her heaving belly. She panicked. She held her breath.

Stevie touched her pussy, sending one finger along the groove of her cunt until the tiny, hooded clit rose from the sucking, slickened folds, rose to be touched.

"Ahhhh… Noooo! Oh Jesus Christ!" Robin cried.

Steve was rubbing the pink clit in circles, forcing it down into the hot meat. She felt new floods of juice rush from her hot pussy. Her heart pounded. She bucked again and drove her heels down on the sofa. It was wrong… had it been anyone else but Stevie pressing against her nakedness, pushing his fingertip up and down her seeping cunt, kissing her mouth with devouring kisses. Had it been anyone else she would have already fainted from fear or screamed or pissed in her panties. But it was Steve. Her brother. She trusted him, loved him.

"No! Oh God nooo! Steve let me up or I'm going to scream for Marcia… I'm not kidding. Ohhhh God!"

It had taken her a second to realize what it was that had replaced his finger. It was something smooth and hot and rounded and it quickly became soaked with her slick cunt-juice. Steve was rubbing it up under the silken band that covered her pussy.

It was his cock!

He was swishing it back and forth through the lips of her cunt, rubbing it over her clit. He jabbed his prick against the tumid, blood-filled clit that grew from her soft folds like a tiny penis.

It was Stevie's cock!

Crying, heaving with dry sobs, she pushed her hands down, tried to push his pelvis away from her. But her legs were parted around his hips. She could get no leverage and she was weak besides. The steady, feathery friction continued. Steve had his hand on his cock, moving it like that! Rubbing her pussy with the swollen tip.

She remembered how his cock had looked that morning in his apartment. She didn't think she could bear to see his prick now. Her breath came in strangled gasps. Her eyes wouldn't focus. Something… a steady pulsing tickle was building through her thighs and belly. And in the core of her pussy… way up in that hidden, protected tunnel she felt the beginning of a hot storm. It came at her in waves. She babbled words that made no sense, words she never spoke aloud.

"Fuck… Oh fuck… oh, Stevie I'm scared so scared!"

"Robin, Robin…"

He was kissing her tits again, holding her head with one hand while he worked his cock with the other. Worked his cock furiously in the hot wash of her cunt-juices.

Robin felt so hot, so slick, so itchy good! She gasped, but she couldn't stay still. Even as she knew it was wrong, she thrust her pelvis violently upward, rubbed it against the steely head of her brother's prick.

She thrashed and bucked and wiggled her slim ass, crying out. She clawed at Steve's back. Tears of confused fear trickled down her cheeks. She beat against his back with her fists, the sobbed and hugged him again, writhing her ass in tight circles on the sofa.

"Yiii… Ohhhh!"

She couldn't move fast enough. What was happening to her? Sure, she was coming… she knew that much. But it was like nothing she'd managed before when she had finger-fucked.

"I love you, Robin… Ohhhh Goddamn it… sonofabitch… Ahhhhh… Uhhhhhh Robin!"

She clung frantically to her big brother's shoulders and pumped her hips savagely against his cock as he worked it up and down her slit. She felt the hot slime jet against her inner cunt-lips, felt it bottled by the pressure of Steve's pumping motion and spray back on the inside of her thighs. She couldn't think or worry or be ashamed… not now.

She could only work her slender ass like she would die if she didn't. She humped her hips, then arched and wiggled. The carnal thrills raged over her body, filled her blood.

He rammed his tongue between her teeth, stifling her cry. But she was still crying when she felt him lift his weight from her. She could see the blurred shape of his movements as he knelt there between her trembling thighs, as he pressed the towel down against the soppy, cummy mess that leaked around the edges of her silk panties.

"Robin… I didn't plan anything like this. I just want you to know… I…" He gasped for breathe. "I think it started the other morning when you came over… I didn't realize I could ever want to…"
