Trisha was sitting before her vanity mirror brushing her hair before bed when her brother Josh walked in. She glanced at him in the mirror; her hand paused in the act of putting her dark glossy hair up into a ponytail.

“Hey. What’s up?”

He stood in the doorway, his six foot frame taking up most of the space there. Home from his sophomore year of college, her brother had definitely changed. He was cut, the hard planes of his well tended musculature sharply defined beneath the tight cotton T he was wearing.

“Heard you come back early from your date. Trouble in paradise?” he asked, unable to help but notice how shapely his little sister had become in his absence.

Her senior year of high school had obviously given her time to grow out of the gangly stage that had plagued her throughout the previous three years. Now a graduate, a month past her eighteenth birthday, he was looking at a grown woman, not the frivolous young girl he’d left behind. Indeed, she’d be starting her freshman year at the same university he was currently attending come the fall.

“Yeah, well, Brad was being a dick so I told him to piss off. I’m not a trophy and I’m sick of his jock star bullshit. We’re over as of tonight and good riddance.” She shrugged and finished pulling her hair back. Josh stepped further into the room and she turned to face him.

“How ‘bout you? Why didn’t Steph come home with you?”

He stared down at his feet, his hands fisted in his jeans pockets, an angry flush staining his cheeks. “I kinda caught her in bed with my roommate.”

“Oh shit! That sucks, hon. I’m sorry.” She stood then and crossed the distance between them to hug him.

He wrapped his arms around her and held her tightly. She felt so small to him, the top of her head barely reaching his chin. He breathed in the scent of her hair. It smelled amazing, sweet and fruity.

He was also acutely aware of the soft feel of her breasts as they pressed against his chest. Wearing nothing more than a light cotton sleeveless tank, it wasn’t difficult to quickly know the details of her anatomy. Sucking in a breath of air, he pulled back and away from her. What the hell? He thought to himself. This is my sister.

Trisha was stunned at what she was feeling. When she’d felt Josh’s body pressed to hers she’d had a nearly overwhelming desire to kiss him. And not in a sisterly peck on the cheek kind of way, but in the steam up the windows and tear up the bed sheets kind. She peeked at him through her lashes, heat flushing her face. God, if he could picture her thoughts, he’d run right out of here and never speak to her again.

He cleared his throat. “So.”

“Yeah, so,” she muttered back.

“You look really good, Tishy,” he said, using her childhood nickname.

“Yeah? Thanks. So do you. So what, are you like a total gym rat now?”

“Something like that. It’s good for tension relief, anyway. So what happened last year? You went and grew up on me and now you’re this beautiful, intimidating woman.” He smiled at her.

Blushing, she stared at her pedicure. “You’re embarrassing me, big brother.”

“I’m not trying to, it’s just the truth.” He tipped her chin up to look at him before brushing an errant strand of hair that had escaped her ponytail back behind her ear. She caught his hand and held it there.

Both froze, staring deep into each other’s eyes, searching for an answer to the unasked question that hung between them. Taking the initiative, Josh cupped the back of her neck and leaned in closer, his mouth a mere inch from hers. If she closed the distance, then he’d know.

She wasn’t breathing. Time had stopped and she was immobile. What she was feeling for her brother was clearly shared by him for her. Could they do this? Should they? God, what if their parents found out? Thank God they were gone for the weekend! All those thoughts and more scurried through her mind in less than a second. And in that second she decided. This was what she wanted.

She closed the distance, her lips meeting his. It was a feather light touch, barely a whisper. Both were trembling with a mixture of emotions. Fear, excitement, arousal, and a truth neither one could quite name. Josh deepened the kiss. Their lips parting, tongues meeting, he pulled her tight against him once again. This time he wasn’t going to back away.

She felt his erection through his jeans, and through the thin cotton of the boxers she liked to sleep in. She rubbed that most sensitive part of her against him, feeling her young sex swell with need. He lifted her then, wrapping her legs around his waist. They devoured each other’s mouths.

Tongues, and teeth, and lips explored every contour, every dark hidden corner. He ran his mouth down the long line of her graceful throat. She purred at him before sinking her teeth firmly, though not painfully, into his shoulder.

Growling, he tossed her onto her bed and quickly began to pull his shirt off over his head, toeing his shoes off at the same time. She was rapidly shedding what little she had covering her as well. He reached for the button of his jeans, but she slapped his hands away and undid it herself.

She slid them down his hips letting them fall to pool on the floor. His cock was straining against the elastic waistband of his boxer briefs. She paused then, partly out of nerves, and partly to draw out the suspense.

Delicately, she brushed her fingers against him and his cock twitched. She grinned up at him, and then slowly slid her fingers behind the waistband. Then, with excruciatingly slow momentum, she slid them down his legs to join his jeans, freeing him at last. She tenderly wrapped her long slender fingers around his hot length and began to stroke him. His head fell back as he closed his eyes and just let sensation overwhelm him.

When he couldn’t take it anymore, he stopped her by taking her wrist and laying her back onto the mattress, kicking out of his pants as he did. He kissed her again, his hands roaming her satiny skin. Her hands were like heaven on his chest and back, and gingerly he cupped one firm full breast, pinching the nipple between thumb and forefinger.

He rolled it around slowly, firmly, all while his tongue explored her mouth thoroughly. She moaned her pleasure into his mouth, suckling his tongue and chewing lightly on his bottom lip. It was as if being sister and brother gave each of them some instinctive knowledge of what the other liked. There was no fumbling, no awkwardness.

Breaking the kiss, Josh replaced fingers with tongue and teeth and began to feast at her breasts. Her breathing was coming in gasps and hisses as pleasure shot electric currents straight to her now throbbing mound. She was no virgin, but the encounters she’d had up till now had all been a pale imitation of pleasure. She couldn’t believe that her brother, of all people, was showing her just how incredible sex could be.

“Yes, Josh, God! Just like that,” she whimpered breathlessly.

“You taste so good, Tishy. Oh God.” He was cradling her hips with one hand and holding her breast with the other as he moved his mouth from one to the other, sucking, licking, biting, twisting.

“I want to taste you, big brother. I want you in my mouth,” she begged him.

He kissed his way back to her mouth, feasting on it before rolling onto his back and pulling her on top of him. She trailed her mouth from his, down his neck, circling his nipples with her tongue before sliding it down the hard, washboard contours of his stomach. She slowed then, lightly peppering his abdomen with baby bird like pecks and licks.

She laid a perforated trail from his navel to the light dusting of hair that spread from just above the base of his cock to behind his large sac.

There she paused to breathe him in. His scent was at once both familiar and alien. This was her brother, but the muskiness of his nether regions was one she’d never known before this moment.

She once again trailed her fingers down the length of his shaft, fondling his balls before tracing their way back up to the thick mushroomed tip. She slowly guided it to her parted lips. Trisha lightly brushed the tip of her tongue across the tip of her brother's swollen cock head.

There was the tiniest drop of pre-cum there and she was thrilled by the musky and salty taste of it. Licking it like a hard candy first, she got it wet all around before finally wrapping her lips around it and sucking it deep into her mouth.

Josh felt his eyes roll back into his skull when his sister took him fully into her beautiful mouth. She sucked him like she’d known his cock her whole life. In truth they hadn’t been naked together since they were toddlers and oblivious. He wasn’t oblivious now. He was delirious. Never had a girl worked his cock so well that he could barely hang onto his control like this. He felt like he would pop his load in ten seconds flat.

“Good God, Trisha! Where did you learn to suck cock like this?” he groaned.

She simply smirked at him before continuing. She was getting wetter and wetter the more she sucked Josh off. She was more aroused than she’d ever been in her entire life. It was painful, but it was a good kind of pain. One she wanted to draw out to the last. She could tell Josh had a slippery hold on his self control and she could only guess that when he reached down to start tugging at her nipples, it was to distract himself somewhat.

Her own reaction surprised her however. It had such an instant effect on her pussy that she literally almost choked herself on his cock. She had him all the way in the back of her throat now, swallowing around his head while her tongue snaked around his shaft and her lips massaged his base. She was even able to lick his balls and tried to suck one into her mouth alongside his cock.

Her mouth couldn’t open wide enough, however, so she stopped trying and just kept licking and swallowing. Every minute or so she’d let up long enough to take a few desperate gulps of air before diving back in. Josh couldn’t take it anymore. If he waited any longer, he’d lose all control and they’d be done before they’d really even started. Reluctantly he pulled her off of him and pushed her back onto the pillows.

“It’s my turn, baby sister,” he declared, grinning devilishly at her before he began the slow and excruciating process of kissing her from head to toe.

Starting at her delectable neck, he licked and kissed, nipped and suckled down to her collar bone, then at each delightful nipple, and along her slender rib cage. He nuzzled across her supple belly and, intentionally bypassing her sweet center, down her hip. He traced the outside of her thigh, all the way to her ankles then back up again until he was hovering on the inside of her thighs. Taking his time, he slowly worked his way to her young womanhood.

Using his fingers to lightly explore her most secret place, he gently opened the soft, fleshy petals of her pussy. Sliding a saliva-slickened finger up and down the creases and folds of her sex, he introduced himself to his sister in the most intimate way possible.

Then he slid one, then two fingers deep inside her wet hole and began to stroke her inner walls firmly but teasingly. He was looking for that sweet spot, that firm little internal button that, when the time was right, he would abuse so fantastically that she would scream herself hoarse.

“Mmmphh, Josh! Oh.” She mewled.

Finally he slid his tongue along her slit and sucked her clit between lips and teeth. She hissed a breath in between her teeth as her hands fisted in his hair, holding him tight to her. She arched up to meet him and he responded by laving her swollen flesh with reckless hunger.

He worked her up into a frenzy and when she finally exploded around him, her heels dug into the mattress, her back arched and her scream was piercing, and so shrill, he feared for the glass in the windows and mirror.

He couldn’t wait any longer after that. He rolled her onto her stomach, pulled her hips up with an arm and plunged deep inside her still quivering hole. She cried out in shocked pleasure.

“God! Oh, yes, God, please. Fuck me, Josh, fuck me so hard. Fuck, fuck, harder, harder, more! Please!”

Hips pistoning, thighs slapping thighs, he went wild on her.

“Yes, Trish. Oh, FUCK!” He growled and grunted, never slacking in his rhythm.

She screamed her release and he flipped her over again. Pulling her onto his lap with her legs over his shoulders and her hips resting on his knees, he bent over her and thrust deep, sheathing himself completely. He was so deep inside her she could feel him in her belly. God he felt so good. And they fit together so well, one might think they’d been custom made for each other. And still she wanted more.

She wanted to try everything. Any shyness she might have felt was gone in the heat of primal sex. And with her brother, whom she trusted above all others, she could ask without fear for what she wanted.

“Josh, I want you to fuck my tight little ass,” she breathed, and for the life of him he almost lost his load right then and there!

He thrust once more before pausing to simply hold her against him while he fought valiantly for control. His breathing ragged, his hair plastered by sweat to his forehead, he finally sat back and slid out of her heaven.

He positioned her onto her back and propped her hips with a pillow before sucking on a finger and gently probing her nether hole.

“Have you ever done this before?” She shook her head no. “Okay then, I want you to relax and just let me guide you.”

“Okay.”

He slid one finger into her puckered little entrance and paused when he reached the first knuckle. He looked into her eyes for reassurance and she nodded. He slid it past the knuckle all the way in, then slowly pulled it nearly all the way out. In and out, in and out getting a good rhythm going, every once in a while spitting on it for added lubrication. She was moaning and her breathing was labored from pleasure.

“More, please. More.”

He increased his tempo, then, added a second finger. He could see she was really getting into it then and with one final hard thrust, replaced his fingers with his cock. She cried out with need. Rubbing a little more saliva around her hole, he fucked her tight little ass with care first, then with intensity, and finally with wild abandon.

They were both screaming and grunting and growling. She came again, and again, and again. It was wave after wave after wave of intense pleasure so acute, it was overwhelming.

She dug her fingers into his shoulders. “Cum in my ass, big brother! I want you to cum in my pretty little ass!”

And with her last breathless command, his control snapped. He pounded into her one last deep thrust before he spilled his seed into her rear canal. He collapsed on top of her, his chest heaving. His member was finally shrinking even as it throbbed it’s last inside her. Finally he slid out of her and rolling, pulled her onto his chest where he held her.

She turned her face up to his. “Wow!”

He nodded. “Yeah, I know! I guess it’s a good thing we’ll be going to college together in the fall because after the summer that I suspect we’re going to have, we wouldn’t survive a week apart.”

She laughed. “Thank God!”
