Role Playing Sessions

Kari nervously waited for her phone to ring as she finished her last day of her job before summer. She'd called her little brother Tim two days before and begged him to intercept any letters from her college. It was her sophomore year, but she'd behaved more like a Freshman than ever before and had failed nearly every single class, landing her on academic probation.

Her little brother had been the coolest, as usual. They'd always been close, and she'd genuinely missed him all year. The thought of hanging out all summer with him was more pleasing than it would've been for most of her friends who had little brothers, but that was just the way they'd always been.

Being the geek that he was, he'd even "hacked" her parents' email accounts and set up a filter to prevent the school from notifying them that way. Now all she had to do was wait for the call.

Her phone rang. "You owe me big time," she heard her brother say.

"Oh my god! You got it? Thank you so much, Tim!" she gushed.

"Damn, you did really bad," he joked. "Fuck, Sis! Wow. Did college make you get dumb or something?"

"Very funny, brat," she teased back. "Burn it, please," she begged, sobering up.

"Well...I was thinking of holding on to this. In case, you know, I ever need you to do something for me. I mean, I could redirect those emails back to mom and dad and accidentally drop this letter in Mom's purse."

Tim had no idea what he actually wanted, he just loved being in the position of having one over on his big sister.

"Noooooo," she half begged/half laughed. She knew that Tim would never do something that cruel, but she also knew that he'd basically saved her life.

"Burn it and I promise I'll do anything you want, ever!"

"Anything? Ever? That's a big promise, Sis," he teased.

"Burn it, dork. You have my word. Mom and Dad would've killed me if they'd found out, I owe you my life!"

"Okay, okay, no need to get so dramatic, Sis. You're not in the drama club anymore."

"Very funny," she said as the flood of relief washed over her. "I'll be home tomorrow afternoon. Be thinking what you want. I've gotta run though, my boss is giving me the evil eye. Love ya, Little Bro."

Tim ended the call and fell back on his bed. He could ask for money, but there wasn't really anything we wanted that bad. Besides, Kari was probably broke.

"Of course, with a body like that, she could make money any time she wanted," he joked out loud to himself. He felt his dick swell. It always made him horny to think of his hot sister in lewd ways.

She was never overtly sexual with him. Of course, with DDD tits, she was kind of overtly sexual just by existing. But she was always kind and playful with him. That was probably part of why he always got so hard thinking about her: she's hot; it's taboo; and he already felt close to her.

"No way," he told himself as the thought crossed his mind.

He took out his dick and stroked it as he mulled the idea over. He imagined Kari on her knees, topless, taking his cock into her smiling mouth.

In the next heartbeat, Tim was no longer thinking with his brain. He found some matches, lit the letter on fire, and dropped it into the metal wastebasket in his room. Then he took out his swollen cock and took a picture of it with the burning letter in the background. He put the message "Take my virginity" on it and sent it.

"What the fuck did I just do?" he wondered. His head was buzzing with adrenaline. "I just sent a dick pic to my sister -- at work! Holy shit, holyshitholyshitholyshit!!!!"

Kari felt her phone buzz and pulled it out of her pocket. As she looked at the message she nearly dropped her phone.

What she could only assume was her brother's small-ish cock was standing erect in the foreground of what was quickly becoming the ashes of the incriminating evidence. Next to that, the message made perfect sense.

Rather than being grossed out or offended, Kari was merely dumbstruck. Her brother wanted her to fuck him? She'd never in her life though of him that way, but she was no stranger to being the object of guys' desires. Hell, flirting with her horny teachers in high school was the only way she'd even gotten into college! So was it really surprising that her dorkish little brother, who'd never even mentioned having a girlfriend once, would want to fuck her?

She smiled to herself as she typed out her response. "Deal. ;) '

As she hit send, she felt a deviant thrill. She was doing something terrible, but it was what her little brother wanted, and he'd more than earned that from her.

Tim was lying on his back in bed, stroking himself when the phone chimed. He pulled it out to see her response. Within seconds, he was shooting cum onto his sister's avatar in his text messaging app.

After he came, he fell back panting. He couldn't believe it. Surely she was just kidding. I mean...she wasn't grossed out?

"Oh my god, I'm going to fuck my sister," he moaned. "My hot, slutty..."

He texted her back quickly, his fingers sliding in the jizz on his phone. When he hit send, he couldn't believe himself. This was too much. The message read "I just came all over my phone. Get home soon."

As Kari read the response, she was shocked to feel how much her pulse raced.

"Oh my God!" she gasped as she imagined her little brother spilling his cum to her thought.

Her fingers were trembling as she typed out her response. "Omg, that's so....hot! Stay hard for me little brother,I promise your reward is going to be worth it."

Kari couldn't believe that she'd sexted her 16 y/o brother as she hit send.

As soon as she was off work, Kari hurried back to her apartment where she packed up for the next day. Although it was hard to get sleep that night, she managed a few hours before getting on the road for home.

With each mile that she passed, she found herself imagining what it would be like. The thrill of the taboo act made her heart race and she mastubated several times on the drive home, one hand in her pants and the other on the wheel.

It was nearly 1 pm that Saturday when she finally pulled into her parents' driveway, and she was disappointed to see both of their cars there.

"Fuck," she thought to herself. It wasn't that she didn't love them, it's just that...she had other goals.

Still, as she walked into the front door wearing a pair of tight, low-cut jeans and a thin, body hugging orange shirt cut low to accentuate her ample cleavage and short to expose her midriff, she smiled to see her mom and dad sitting on the sofa in the living room.

"Sweetheart," her mom said as she came over to give her a hug. "How was school? Happy to be done?"

"Oh yeah," she said as she hugged her mom back tightly. "I'm so ready for the summer."

"I bet you are, kiddo," her dad said as he gave her a hug too. "So tell me, what're your grades looking like? All A's I hope?"

"Oh yeah, Dad," she said a little bit nervously. "Well, maybe a B+ thrown in there, but mostly A's."

"That'll do I guess," he said with a smile, just as Kari heard the thunderous sound of her brother's footsteps running down the stairs.

"Kari!" he said with excitement.

As she grinned at him, they shared a look. A look that knew both had a dark secret of the other, and that only made their relationship stronger.

"OMG, you little dork, you've grown so much!"

As he ran over to wrap her in a hug, she squeezed him back tightly, pressing her large breasts into his chest.

His back was to their parents, and she couldn't help taking a bit of a risk.

"Squeeze my tight ass," she whispered into his ear

Tim felt her warm breath in his ear as he savored the soft pressure of her huge breasts against his chest. Then when her request finally reached his brain his cock started to swell between them.

He lowered his hands from her back to her bottom. He could feel her breathing on his neck. Her round mounds fit perfectly in his hands as he squeezed a handful on each side and quietly gasped, "Oh, Kari!"

"Well, somebody missed his big sister," their mom joked. Turning to the kitchen, she added. "Tim, help your sister get her bags in from the car."

He reluctantly released her ass. As they broke their hug, he felt completely horny and completely embarrassed. Kari tucked her hair behind her ear and actually blushed and looked down at the floor. When she did, she noticed the lump in his pants that she'd felt pressed against her.

"Come on," she said, letting her fingers brush against his erection as she turned and let him to the car.

"Are you...I mean...We...I just..." Tim blurted once they were outside and out of earshot of the parents.

"Yes," she said, pulling him into the bushes on the end of the garage. "And yes and yes and..." In the shadows, she sank to her knees in front of her brother.

"I masturbated the whole way here thinking of you..." She reached up and laid her hand on his erection. "...of this." She leaned in and kissed it then unzipped his pants.

"Do you want to do it in my mouth or on my tits?" she asked, as she took his dick out of his pants and started stroking him. She pulled her massive tits out through the neck of her shirt. "I'm torn because I want to taste your cum so bad. But I also want to be covered in it. I want you to cum on me like you came on your phone for me. I owe you so much and..." She looked up at him with her big, doey eyes. "...you're my little brother and I love you." Then she licked the underside of his cock and moaned.

The sensation was unbelievable for Tim. He'd stroked himself hundreds of times before, but to feel his sister's soft, warm tongue licking his cock was unreal.

"Unggggg," he grunted as the most difficult decision of his life presented itself. "I....I. uhhhhhh....i-if I do it on your tits....will you let it stay there when we go inside?"

The thought sent a thrill through Kari as she understood the risk. "Of course!"

"O-ok," he said with a bright grin. "I'll tell you when."

Kari gave him one more endearing smile before she opened her mouth and slid it over his 4" cock. She was no stranger to blowjobs, and she easily fit the full length of his cock in her mouth, hungrily slurping at it as she began to slide her head back and forth.

She could hardly believe it. Her own brother's penis was in her mouth! The moans quickly began to escape his lips and for a moment she almost wanted to tell him to be more quiet, but she couldn't. There was no way she was going to begrudge him the right to moan for his first blowjob.

"Oh God Kari!" he suddenly gasped, less than a minute into the blowjob. "Here I cuuuuuum!"

She'd barely taken her mouth off of his cock when it began to spray it's clear, running cum over her tits. Some globs were more milky white which stuck to her flesh while the rest ran down her heavy mounds into the valley created by her tits; streaming along her stomach to pool in her belly button.

"OH FUCK SIS," he moaned, trying to force himself to be quiet, but failing mostly.

"Yessssss," she hissed as he coated her tits with his cum. "Cum on me baby brother! Cum all over my big tits!"

Tim's knees buckled, and his breath caught in his throat as Kari jacked him onto her chest. He could barely breathe, but she was moaning.

"UUNNGGGHHH!!" he grunted loudly.

"Yes, your cum feel so hot. It's dripping down into my cleavage. Oh, Tim, I love the feeling of your cum on me!"

Tim opened his eyes to see the look of genuine delight on his sister's face.

"My own brother's cum!" she gasped.

Once his cock spasms subsided, she sucked him dry, moaning at the flavor of her brother's cum.

"Ohhhh! MMMmmmmm, you taste better than any boy I've ever had," she gushed. "And I'm not just saying that," she added, looking up at him. "I can't wait until I feel it inside my pussy."

She stood up, shaking her painted tits in front of him. She lifted his hands to her large areola and let him grope her.

"Do you like them?" she asked.

Unable to speak, Tim merely nodded enthusiastically.

"They're yours. I'm yours. The whole time I'm home this break, I belong to you. I can't thank you enough for what you did for me."

Karin tucked her cum-covered tits back into her t-shirt. The cum immediately started soaking through her shirt. She giggled when she looked down at it. Then she reached up and, putting a hand behind his neck, pulled him to her and kissed him.

"We better get my bags in before they get suspicious," she said, and she pulled him by the hand back to her car.

As they carried the bags into the house, her mouth glanced over.

"Oh, Kari what happened to your shirt?!" Her mom asked.

"Oh, Tim was just a klutz & spilled something all over me. I can't stay mad at him forever though."

She said with a wink back at her little brother.

"Well, help your sister get her things put away, Tim, and try to be more careful. She's only been home for 10 minutes."

As they carried their things up the stairs and into her room, Kari closed the door behind them and then dropped her luggage.

She immediately began to undo her jeans as she kicked her shoes off.

"Come on, I can't wait. I've been wanting to show you my pussy and ass and tits every since you showed me your cock!" She was more thrilled than the first time she'd ever fucked, and the excited, almost daunted even, look on her brother's face only made her want it more.

She pushed her pants down, stepping out of them and lifted her cum-stained shirt over her head.

As she finally stood there, with her hairless cunt, heavy, sagging tits, and bare stomach exposed, she placed her hands on her hips.

"Do you like me? God I've never wanted to fuck anyone so much in my life, Tim! I don't care if mom and dad are downstairs, i want to fuck you now!"

" Like you?!" was all Tim could muster as he stared at his sister's body. He stripped his t-shirt off, unfastened his pants and pulled them down to the middle of his thighs. His deflated cock was already starting to fill up again. His eyes fixated on her bald cunt, her tight belly, her enormous tits.

"I've been jacking off to you ever since my first wet dream. It's way beyond like," he said.

"But I don't..." He looked down at her pussy. "I mean, I have the general idea, but I've never...Do I just put it in?"

"Ohhhh, Baby Brother," she said, pulling him to the bed by the neck. "You were so good at cumming on my tits, I almost forgot this is your first time."

She lay back on the bed, spreading her legs wide to him. "I don't know about other girls, but with me, you can always just stick it in. I'm so wet for you, Tim."

His cock throbbed back to life with each beat of his heart. She was mesmerized as it rose with each pulse.

"But what if, like...only I cum and you don't?" he asked sheepishly.

"I don't care," she said, looking up at him, feeling so much love toward him. Even when taking advantage of her, he was goodhearted. "I just want you to cum in me, Tim. It felt so good to feel your cum on my tits. If you do it inside my pussy, I think...I think I'll cum just from the sensation of knowing that I gave you pleasure."

"But what if I lose control and hurt you?" he asked.

She could see the worry on his face.

"Tim, Baby," she crooned, pulling his face down to hers. She kissed him deeply. "Just do what feels right in your body. Fuck me, Tim. Fuck me as hard as you want. And if you hurt me..." She smiled fiendishly, "...well, then that's just extra."

Kari reached down and guided her brother's throbbing, hot member into her pussy. When he felt her wet labia greet him, he flinched and moaned. She wrapped her arms around him and grabbed his waist and pulled him into her.

"Unnghhh," she moaned. "Oh fuck! That feels good. Does it feel good to you, Tim?"

She couldn't believe she had her little brother's cock inside of her. It was so wrong, so messed up. But it felt so perfect. She'd never felt more intimate and more connected before. It was like she was losing her own virginity all over again.

"God yes!" he moaned. He pulled back and thrust into her.

"Yeah! Just like that!" she encouraged him.

It didn't take long until Tim was fucking her. The sound of her wet pussy sloshing filled the room.

"Harder," she whispered.

Tim obliged. His hips hit her cunt over and over, making a "clop clop" sound as he pummeled her. His intensity increased, and she moaned and arched her back.

"Yes!" she whimpered. "Harder, Tim. God, fuck me harder!"

No one ever would've accused Tim of being an athlete, but he'd watched enough porn to know the basics, and the intensity of getting to fuck his own sister spurred him on. Instinct began to take over and he began to realize that he could do no wrong with Kari.

"Ughhhh yesssssss!" he grunted as he thrust into her, harder and harder, causing the bed to squeak, adding to the noise of her wet, sloppy cunt getting pounded.

"Oh god, Kari! Your pussy feels so goooooooood!"

"Yes! Yes! Yesssssss! Fuck me, tim! Fuck your sister's incestuous cunt!!! Plow me with that big hard cock! Fuck me with that 4 inch monster!"

She wrapped her legs around his waist, pulling him down with each of his thrusts and raising her own hips to meet them, adding to the rhythm and the sound.

"Yes! Oh God yes, Sis! I love you, Kari! I love how sexy you are! I love your big floppy tits and your messy vagina! I've never seen anyone so hot as you!"

He couldn't resist and lowered his mouth to wrap it around one of her nipples. He began to suck on it, savoring the taste of her sweat, his cum, and her flesh as she held his head in her arms, as if he were a suckling babe who was simultaneously plowing her cunt.

"Yessssss, suck my tits, Baby Brother! Suck my big tits like our baby's going to do!"

The thought had escaped her lips before she realized she'd even had it, but they found her brother's ears just as quickly.

He moaned as he seemed to thrust harder, sucking one tit while groping the other wildly, lost in the vice of his sister's body.

He'd often sucked his own thumb while masturbating, imagining it was his sister's nipples, but now, her huge tit was in his mouth. She was pressing his head down and thrusting her chest up to him. It felt so good.

When he heard her mention getting pregnant, he looked up to meet her eyes as he continued to suck her tit and hammer her cunt.

"I'm not on birth control, Tim," she moaned. "And I think I'm ovulating, and...and...ungh...I want you to cum in my pussy."

Tim couldn't believe what she was saying. She wanted his baby. She wanted him to impregnate her.

"Please," she whimpered. "And if you don't knock me up today, I want you to fuck me every day until...OH GOD!...I want to be the mother of your babies, Tim!"

Kari couldn't believe what she was saying, but there was no denying the truth of it. She imagined her belly all swollen with his child; her tits even heavier, laden with milk. She'd drop out of school and move back in with her parents. She'd get a job at the Dairy Queen and work it until her water broke. Then she'd birth her brother's child and beg him for another one.

"Please!" she begged loudly. "Breed me, Tim!"

His sisters words were so perverted, so honest, so full of vulnerability. He couldn't deny that he'd had the same fantasy. Of course, there were very few fantasies he hadn't had about her.

He let go of her nipple with his mouth and found her lips. "Okay," was all he said, as he kissed her -- his sister, his lover, his...future baby mama.

"I love you," he gasped as he felt his climax building. "I'm going to cum, Kari. I'm going to cum in you and make you a mommy. I'm gonna...I'M GONNA CUUUU-UUUHHMMMMM!!!"

As she felt his semen flood into her fertile womb, bliss washed over Kari. Her vision for the future was about to come true.

She felt his cum spraying into cunt and her womb. She knew she was unprotected, she knew she was surrendering herself to her little brother's cum and it felt better than anything in her life.

She shoved her tongue into his mouth as she wrapped her legs around him and began to cum. She moaned into his mouth as he moaned into hers. They were one in that moment as their bodies intertwined and they shared juices in multiple ways.

Their bodies writhed and jerked atop one another. Their cum mixed in her pussy as their saliva mixed in their mouths.

Their only saving grace was that their moans were muffled by the other's mouth. In that moment though, they knew that they were one together.

As their orgasms slowly began to subside, their writhing began to slack. When Tim finally rolled off of her, his cock slid out with a wet plop and their mixed cum spilled out, soaking into her mattress.

"Holy fuck, Sis! We...we did it!"

"We did!" Kari said with a grin, holding his head as her heavy tits rose and fell.

The sight was so appealing, and he desperately wanted to try something. Before he never would've dreamed of it, but with all that she had said, Tim believed his sister when she said anything was possible.

He climbed atop her body and scooted forward until his hips were straddling her neck. Using her tits as cushions, he sat on her chest and then gently lifted her head, guiding it to his crotch.

"Can I use your mouth to clean my cock?" he asked?

The dirtiness of it thrilled Kari, but especially his imagination to even come up with it.

"Of course, Baby Bro," she said with a grin.

As he pulled her head to his crotch she opened her mouth and let him rock her head back and forth with his cock in her mouth.

She loved that he was making her useful. She had never tasted a guys cum mixed with her own before. Knowing that this mixture might be the very thing that got her pregnant made her swoon with delight. She relaxed her neck and let him take control of her head using her however he wanted. When he repositioned himself so that her mouth was even with his balls, she didn't think for a moment of stopping. She loved the nubile hair growing in on them. She licked them fervently, tasting her own cum that must have dripped down when he made her gush.

Tim looked down to see the bliss on his sister's face as she serviced his testicles.

"Those balls have the seed that is going to make you pregnant," he said.

"Mmmmm," she crooned. She looked up at him from beneath him. "Everything about them is precious to me: their insides and their outside."

Her warm, wet tongue felt amazing as it traced around his sack. Then she gently squeezed the scrotum just above the testicles, making the sack swell up, and she rubbed her wet, puffed out lips over them.

"Hey, Tim," she asked, sheepishly, looking up at him. "I've always wanted to try something with a guy, but I've always been too shy to do it. Will you sit your ass on my mouth and let me lick it?"

The very act of asking the question made her belly tense with desire. She loved how hard he'd fucked her, how brave and gently demanding he was to make her clean his cock. She wanted to serve him more. She wanted to be everything for him by being nothing before him.

Tim didn't reply. He simply scooted up further until he felt her tongue between his ass cheeks. He reached down and spread them wide for her. When her tongue pressed against his anus, he moaned.

His mind had been too obsessed with what would happen that day to have even thought of showering, and it had been two days since his last one. Hours of masturbating and then sex had caused him to sweat as well, giving Kari a foul, rank introduction to eating ass.

Rather than being disgusted, though, she embraced her brother once again. She buried her face into his spread ass cheeks and ran her tongue over his crack. The mixed taste of sweat and filth spread over her tongue as she licked it up and swallowed, then did it again.

As Tim knelt there, having his asshole cleaned by his sister, he knew there was nothing that was beyond her. He could do anything he ever wanted to her, and he knew she'd accept it with love.

After letting her clean him for a few minutes, he got up off of her face.

"I better go before Mom and Dad get suspicious," he said.

As cool as he was trying to act, his legs were shaky, and his hands were trembling as he pulled his pants back on.

"Okay, yeah," she replied. "But..."

Tim looked up at her as he fastened his jeans.

"...promise me you'll sneak in tonight and fuck my pussy again. I'm serious, Tim. I want..." She gulped as tears started to fill her eyes. "...I want you to put a baby in me. I want it like I've never wanted anything before."

Tim pulled his t-shirt on and walked over to her. He leaned over and kissed his sister. She melted under his mouth.

"I promise, Sis. I want this too."

And with that, he turned and left here there with his cum leaking from her cunt and the taste of his ass in her mouth.
