It had been almost a week since Mark, Angie and Julia had spent the evening together. Mark and Angie had barely spoken since then, both teens were very involved in after school programs and sports. Although they seen each other briefly in the evening neither of them had brought it up, it wasn't so much shame as it was embarrassment, and that awkward stage where neither knew what the next step was.
It was now Friday evening, the teens parents had gone out to a couples house for a party and weren't coming home until the next day.
Mark had been hanging out in the living room when Angie got home, she smiled awkwardly and went upstairs. After about 30 minutes Mark thought it was weird that Ang hadn't come back downstairs so he decided to check it out. He made his was upstairs and knocked on his sisters' door.
"Hey Ang, I was wondering what you wanted to do about dinner? The parents left us some money" Mark called through the closed door. He waited a while, but there was no reply.
Mark knocked on the door again and slowly opened the door. "Ang... is everything OK?" He said as he peaked his head into her room.
He saw Angie laying on her bed, it appeared she had changed into PJ's already. Mark entered her room and sat on the chair at her desk which was right next to the bed.
"Ang, talk to me... what's wrong?" he asked again.
"Nothing is wrong, we just, we haven't talked about last weekend" she said.
"No, I guess we haven't... do you want to talk now?"
"Kinda" she replied "why don't you climb into bed and put your arm around me"
Mark stood up and walked around the other side of the bed. he pulled the sheets back and went to climb into the bed but Ang stopped him.
"You're not going to wear jeans in my bed are you?" Ang scolded.
"No, I, sorry" he said as he unbuckled his belt, undid his pants and dropped them to the floor. He began to climb into the bed "Um shirt too, it's probably dirty" Ang said. Mark pulled his shirt up over his shoulders and tossed it on the ground beside him.
Mark climbed under the covers and scooted over beside Ang, he rested his head on the pillow and put one arm over his sister. By his best guess Ang was only wearing a night shirt and panties, although he tried not to think about it.
"So, a lot happened" Ang said
"Yea, it sure did" Mark said as he felt himself blush.
"Was Julia your first?"
"uh, um... yea, yes she was"
"Huh, was she your first everything?"
"No, do you remember Jenn? She gave me a hand job, and she put her lips on... it... a few times" Mark was really blushing now.
"Did you like it when I put my mouth on it?"
Mark felt like a deer in headlights... he didn't feel he could possibly have the correct answer to this.
"It was unexpected" he replied.
"That's it? That's disappointing..." Ang said trailing off
"Disappointing?"
"Yea, I was hoping I was better than Julia, but as it seems I'm not better than her at anything" Ang said as she pushed Marks arm off of her.
"Ang, no, wait, I'm sorry, I just. It's just that I didn't know how to respond, you caught me off guard. Ask me again" he said as he put his arm back on her.
"Ok..." Julia rolled onto her back and turned to face Mark "did you like it when I put my lips around your dick"
Mark just about passed out, he didn't expect her to rephrase it quite like that.
"Yes, it was the best thing I've ever felt" Marks cheeks were bright red now, it felt like the room was 100 degrees to him.
"Was it better than the way Julia's pussy felt?" Ang said as she rolled back onto her side facing away from Mark, she pushed her bum into his pelvis now.
"Yes, it was even better than that"
"You wouldn't lie to me would you?"
"No, never"
"hrm, so did you actually shoot your load when Julia licked my shit off her fingers?" She could feel Mark pull his pelvis away from her bum, she figured he was getting turned on.
"I was getting close, and I don't know why but when she licked them I couldn't hold it anymore"
"Really, you don't know why?"
"What does that mean?" Mark said stammering slightly.
"I've been on your computer Mark... do I have to say it"
"I don't know what your talking about Ang...."
"It's OK Mark, I did it for you, you don't have to be embarrassed"
"You did what for me?"
"You're going to make me say it eh, OK fine, it wasn't an accident, I shit for you"
"You shit for me?"
"I did, I saw how turned on you were when you helped me on Friday night. I snooped a little bit and found your browser history and the porn you looked up, the videos of the girls peeing and shiting on each other.
"How, wait, what?" Mark didn't know what to think.
"Mark, it's OK, don't worry about it, it's kinky... and kinda fun"
"But, if you knew, that means you told Julia?"
"Nope, I didn't tell her a thing, it was a risk, I figured I'd blame it on cumming if she was grossed out"
Ang reached back and pulled Marks arm back over her, she placed his hand on her breast, the only thing between his hands and her was the little nighty. She pushed her hips back again, this time Mark didn't pull away, she could feel his hard cock press against her ass crack.
"It's not fair though" Ang said quite definitively.
"What's not fair?" Mark asked.
"That Julia got your virginity, and you got hers, and I got no ones, and no one got mine..."
Mark felt like he was going to choke on cotton balls, she wasn't really saying this to him.
"Ang, I mean, I know you went down on me, but it was in the heat of the moment, I mean you're still my sister"
"I know I am, but why is that so wrong? Because people tell us it is? Do you love me?"
"Of course I love you"
"Do you love Julia?"
"... no, I mean, I don't think I do, I don't really know her that well"
"So it's more acceptable for you to have sex with someone you barely know than it is to have sex with someone you love?"
Mark was caught between a rock and a hard place, there was just no good way to answer this question.
"It's OK, I'll let you off the hook..." Ang said.
They laid there for a while, not saying a word, just spooning.
'prrrrrrrrrpppppptttttttttttt' the silence was broken as a fart ripped from Angie's bum hole.
Angie felt Mark squirm and his cock felt like it was getting even harder, she smiled to herself. 'ppppfffffffffffrrrrrrrrrrrrrrrrrppppppppppttttttttt' a long and steady fart rumbled under the covers. Mark shifted, she knew he was turned on but didn't want to give it away. She smiled to herself, she liked having this kind of control over her older brother.
Angie reached back and grabbed Marks cock through his underwear causing him to moan. She slowly ran her hand down the length of his shaft and back up again. Mark bit his lip and tried to contain his moans. She pulled his cock forward now, still in his boxers briefs, she put the end of his fully erect cock against her butt hole and she strained 'ppprrrrrrrrppppppt......pppfffffffffffffffffffffffrrrrrrrrrrrrrrrrrrrrrrrttttttttttttppppppppttttttttttt' "uh" she moaned loudly.
"Fuck, I could felt that through my underwear" Mark said.
"what, you don't like it?" Ang asked
"No, no that's not what I meant at all"
Ang grinned, she pulled away slightly.
"Close your eyes" she said, Mark did as he was asked. He felt her tug his underwear off, he lifted his butt to help as she slipped it down to his knees and then off. He felt her moving in the bed for a few moments and then he felt her snuggle back up to him. She spread her ass cheeks apart pushed closer now trapping the shaft of his cock between his stomach and her bum cheeks. Marks mind was racing, he felt like he was going to blow his load, just from his cock being between his sisters firm butt cheeks.
Angie closed her eyes, she strained briefly, Mark felt his sisters anus pucker and then he felt as her fart rolled over the shaft of his cock 'prrrrrrrrrrprrrrtttttttttt'"ahhhh" she moaned, 'pppppppppprrrrrrrrrrffffffffffffffbbbbbbbbbbraaaaaaaaaaappptttttttttt' "uh" she moaned again as her back arched. Mark pushed his body forward keeping his cock pressed firmly against his sisters butt hole. 'ppppppprrrrrrrrrrrrrrrrrrttttttttttttiiiiiiiiiiippppppppppppppttttttttttttttt' "ohhhhhhh" Angie moaned, she was now working on her clit with her delicate fingers. Marks hips were thrusting and she felt his cock moving up and down between her cheeks and over her anus stimulating it.
She reached back and pulled his cock, she spread her legs and moved her body so that the shaft of his cock rested against her damp slit, the head of his cock poking out between her legs. "Don't move" she whispered. She gently started rocking her hips, Mark felt the shaft of his cock getting wet from his sister's pussy juices. She slowly worked her slit back and forth along his shaft, completely coating it now. She picked up the rhythm, and worked her clit vigorously now. Mark felt the warmth, the wetness and the tightness of being between his sisters thighs, it felt pretty close to the way it had when he had fucked Julia; he wasn't sure he could hold out much longer. Ang rubbed her clit faster and faster, she pressed her slit harder against her brother's shaft. Oh how badly she wanted his erect cock to be buried inside her womanhood. She rocked and rubbed, her pussy leaking like it never had before and then her body tensed. Mark felt her body still and her legs grab hold of his shaft. He couldn't stop, he was too close, so he pumped the shaft of his cock between his sister's cum coated legs. He thrust, and he thrust, Angie road the wave of another orgasm as she felt the closets to being fucked as she ever had. She felt Mark grab her and pull her closer, and then his pumping stopped, she felt his shaft well and then jerk, she felt the cum hit the sheets against her stomach, it swelled and twitched again, and again as he shot load after load into her bed. As both of their bodies stilled Ang put her hand on her flat stomach, it was now completely coated in her brother's jizz, she rubbed it into her skin, she desperately wish that he had shot his load deep insider her.
They laid in each others arms and drifted off.....
Sometime around 11pm Angie woke up, she no longer felt Marks cock between her legs. She rolled over, Mark was still there. She felt the dried cum on her stomach, it felt slightly crusty now. She nudged Marks shoulder, he slowly opened his eyes and smiled.
"Do you want to have a bath with me?" She asked her brother, Mark wasn't one for baths really, but how could he turn down an offer to bathe with his gorgeous sister. He nodded affirmatively.
Ang got out of bed first and made her way to the bathroom. Mark smiled as he watched her firm ass walk away. He got up shortly after and made his way into the bathroom, Ang had already lit several candles, he watched as the light flickered on her body which was bent over as she filled the tub. His eyes locked in on her bum, her pink bum hole was slightly exposed, and he could see her puffy virgin pussy lips. 'What a hell of a view' he thought to himself.
Ang turned around and caught him staring "like what you see?"
"what's not to like?" he responded
Angie blushed, she looked at her brother's body, it was lean and masculine, not overly bulky but well defined. She looked at his cock, it wasn't erect at the moment. She was much braver now as she took a step forward and took his soft cock in her hand.
"It looks a lot different when you aren't turned on" she said smiling. Mark blushed. "It's not a bad thing, it's nice to see it this way too, it lets me see how big a difference I can make" Marks cheeks were on fire now. Ang turned back around and turned off the tub, she climbed in first and slipped beneath the water. Mark took in the sight of her perky, firm breasts, her flat stomach, and her bald twat as the candle light danced on the water. As Mark stepped into the tub he realised it was only a little while ago that they had been in this tub together.
As they sat together in the tub Ang decided to have a bit of fun, she grunted and then the tub rumbled as a stream of bubbles made their way to the surface.
Mark laughed softly as Ang bit her lip "oops, did I do that?"
"Someone is a naughty girl"
"Who, me?" she giggled, she strained slightly and another stream of bubbles floated passed her bald pussy and rose to the surface. A gentle odor filled the room.
Mark took a deep breath "yep, definitely you"
Ang giggled. "watch" she said as she looked down towards her pussy, Marks eyes followed as he trained his eyes bald mound. Ang whimpered softly and then Marks eyes widened as he saw the water stain yellow. Her pee continued to spreading through the water like vines. Mark slowly tugged on his hard cock as the stream of piss, spreading like yellow ink, subsided and blended in with the water. Ang smiled, she liked that her brother was touching himself, that he enjoyed watching her pee for him. She moved towards him in the tub, "come here a bit" she said, Mark shifted in the tub to accommodate. "stretch out your legs" again Mark did as he was told. She straddled him now, she reached between her legs and spread her pussy lips apart, she lowered herself pressing her cunt against the length of his shaft. She wrapped her arms around his neck and gently began rocking. She glided her slick cunt back and forth along the length of his shaft. She leaned forward and pressed her lips against his, her kissed her back. Their kiss was soft at first, this was new to them, despite everything that had happened the siblings had never kissed before. Mark couldn't believe how soft and velvety her lips were, he pressed his tongue forward softly and Ang opened her mouth receiving it. Their tongues swirled and danced together now. Angie started rocking faster now, using his shaft to stimulate her clit. The water in the tub started splashing over the edge and Ang reached down pulling the plug letting the water drain.
Mark buried his face between his sisters breasts, he sucked on one nipple while squeezing her other tit. With the water drained Mark felt just how wet his sister was, her twat was easily gliding back and forth along his shaft as he continued to suck on her breasts.
"Mark, please, I want you inside me" His sister moaned.
"Ang, we can't, I mean we just, we can't go back from that" In his head he was begging her to stop asking, he knew he wouldn't be able to say no many more times.
"I want to feel you inside me, filling me" she moaned again as she felt him playing with her tits. "what if we did it a different way?"
"How's that?" he asked.
Ang stopped rocking back and forth resting with her pussy lips against the bottom of his stomach, and his shaft between her legs sticking out between her bum cheeks.
"Well... I do have 2 holes down there...." she said blushing
"Uh, um. well yea... but have you ever done anything like that?"
"No, I mean other I've slipped a finger a couple times, and then when Julia fingered my bum last week...."
"I think it might hurt you if you don't have much experience"
"Well, I have a toy that I usually use when I'm horny, maybe you could put it in my bum and we can take it from there?"
"OK, we can see how that goes" Mark said as Angie climbed out of the tub
"come to bed with me"
"Are you sure... last time Julia put her fingers in your bum you had to do a lot of laundry"
"it's fine, just come"
Mark climbed out of the tub and they both dried off, Mark followed Angie into the bedroom and tossed the towel on the edge of the bed. She pulled the comforter back and sat on the edge of the bed; Mark climbed in on the other side. Ang reached into the bottom drawer of the night stand, right to the back and pulled out a small silk pouch. Mark watched with great anticipation as she undid the bag and pulled out a small baby blue dildo, it was sleek and narrow and the tip and widened towards the white base.
"Here" she said as she reached out and handed it to Mark. Mark took the toy and examined it in his hand, he couldn't believe he was holding his sisters sex toy. "If you press the bottom it will start to vibrate, press it again to change the setting, it has 3 or 4 of them" Mark played with the button and felt the different pulsations. "I don't think I have anything we can use as lube though..." Ang said trailing off.
"It's OK, I've got an idea, roll over and bend forward"
"Wow, getting right to it, I like that" Ang said as Mark blushed. Ang turned over and rested on her knees her bum in the air pointed at Mark. "how's that?"
"Just perfect" he said as he leaned forward. Angie jumped, and pulled her bum forward, startled by the sensation she had just felt.
"Did you just...." Ang blushed, she couldn't get the words out.
"Yea, we don't have lube, gotta use something" Mark leaned forward again, this time he held Angie by the waste. Her body quivered as she felt the same sensation of Marks tongue against her asshole. He gently lapped at her puckered anus, then he began swirling his tongue around. Angie's mind was racing now, it tickled, but felt so hot, and yet overwhelming all at the same time. Her knees felt weak as her brothers tongue probed one of her most intimate areas. She moaned loudly as she felt his tongue press firmly on her button, she buried her face in her pillow as she felt his tongue break the seal of her rectum. Her brother's tongue was now darting in and out of her asshole, she had never felt so exhilarated. The licking stopped suddenly and then she felt as he dribbled some spit right on target. She couldn't help but clench as his finger pushed past her sphincter and was buried to knuckle. Her body tingled as his finger probed her bowels, he worked his finger in and out of her bottom slowly and deeply. She felt more spit now, and then she felt the plastic tip of her dildo pressed against her rectum. She relaxed as Mark pushed slowly and steadily, her anus accepted the dildo surprisingly easy as it slid inside her right to the hilt. She rubbed her clit between her legs now as Mark slowly glided the dildo back out of her puckered rosebud before guiding it back in.
Mark worked the dildo slightly quicker, he spit on it again to keep it moist. As he pulled it out he noticed a slight brown streak, he didn't pay much attention as he buried it in again; when it came out it was slightly browner but he was more focused on the task at hand then the staining on the toy. He pulled the sex toy out of his sisters ass and he watched her anus expand and flutter as a warm wet fart burbled out of her.
"OOOps" she giggled "I guess that's bound to happen?"
Mark smiled "I suppose so, it was kinda hot actually"
"you think so? you can try it again if you like...."
Mark pushed the dildo back in her bum and worked it around a few times, he pulled it out quickly, right on queue "pppppppppppppppprrrrrrrrrrrrrbbbbbbbbbbbbbbbaaaaaaaaaaaaaaaaaabbbbbbbbbbbllllllllllleeeeeee' another fart bubbled out of her bum.
"Do you think you're ready for me to try...." Mark swallowed deeply.
"I'm ready, but you can't go in dry, let me get you wet first" Ang said as she rolled over, at first Mark didn't know what she meant. Ang took the dildo out of his hand and placed it on her night stand, she seemingly didn't realise it was stained. Marks eyes widened as he realise what she meant, Ang took the shaft of his throbbing hard cock in her little hands, they were cold to the touch but he didn't mind. She put her lips around the head of his cock, Mark watched as the shaft of his cock disappeared down his sisters throat. She bobbed up and down several times, but she didn't want him to blow his load too soon. As she pulled up for the final time she left behind a thick film of spit on his cock.
"that should do it" Ang smiled slyly as she turned back around and up on her knees, she hugged her pillow as she waited with great anticipation for Mark to enter her body.
Mark looked at his sisters perfect bum, he knelt behind her, getting into position, he spit on her butt hole one more time.
"OK, try to relax, if it hurts let me know and I'll stop" he said, he couldn't believe he as actually about to have anal sex with his sister.
He pressed the tip of his cock against her pink hole, they both moaned as their skin touched. Angie gently pushed out like she was going to poop, Mark felt her anus pucker. He didn't hesitate, he pushed the head of cock in and past her sphincter before it tightened on him. Angie cried out, not in pain but in delight, the feeling of her brothers warm cock stretching her bum. Mark paused this head of his cock had disappeared inside his sisters bum "are you OK, should I stop?" he asked.
"Don't you dare" she begged.
Mark slowly pushed his cock deeper into Angie's bowels, his shaft disappearing inch by inch. He couldn't believe she had taken 2/3 of his cock inside her without hesitation. He changed his momentum now pulling his cock out, but not all the way, the head of his dick still hidden inside her tiny bum. He paused momentarily and he felt Angie's rectum pulsing and contracting. He moved forward again, this time pushing his dick all the way inside. He stopped, he felt the warmth of her sides wrapped around his shaft, Angie moaned feeling so full.
"Mark, keep going, make love to my ass"
Mark rocked back, he hadn't noticed but now his cock had a brown streak on the shaft. He buried himself inside her again, and pulled out, and again, and again. Soon he was moving at a pretty steady pace, he hadn't realised why it was getting easier and easier to fuck her. His cock was now completely brown, coated entirely in a thin layer of his sisters warm shit. He held his sister by the hips and started pulling her towards him each time he drove his cock into her rectum. She was whimpering steadily now as he continued to steadily pump his cock in and out of her. He was afraid to look down, he thought if he watched his cock sliding into his sisters ass he would surely lose it. The downside to not looking down was neither of them realised that soft shit was now oozing out of his sisters bum, there was quite a bit of it now, there was some on his balls and on it was dripping down across Angie's pussy.
Angie reached between her legs to work her clit and that was when she realised it was too wet, she pulled her hand forward and saw her fingers were coated in shit. 'oh fuck, he's literally fucking the shit out of me', She reached back between her legs and worked her clit hard, but it didn't take much before she started to cum, her cunt swelling juices that were mixing with her shit. Mark could feel her anus contract hard on his cock now, he was surprised, he had a pretty good idea she was having an orgasm. What surprised him most was that he had lasted longer than her, he looked down and it hit him what had made her cum, there was thick soft shit everywhere, on his cock, his balls, dripping all across his sister cunt, smeared against her ass. Then realised her hand was brown, she had been fucking herself with her own shit and didn't care.
"I, I need to pull out"
"Don't, don't stop, please"
"UHHHHHH" Mark gasped, his body stiffened and his cock pulsed as he shot his first load. Angie felt his cock jerk and throb side her, which sent her over the edge again. The came together as Mark shot load after load into his sisters bowels. He pumped his hard cock out and back in again, he felt the mixture of cum and warm shit. He was done, his body was weak, and they collapsed into a pile with him on top, still inside her. As they laid their in a messy pile of sex Mark felt his erection subside and his cock slipped out of her bum; followed by a long squeaky, wet fart. "ppprrrrrrrrrrrrrppppppppppppppppppptttttttrrrrrrrrrrrrrrrrriiiiiiipppppppppptttttttttt" Mark felt his own cum, spitter and splatter out of her bum hole. 'ppppppppppppprrrrrrrrrrrrrrffffffffffffffftttttttttt' another fart caused her anus to gape, this time more of his cum sputtered out of her, he looked down and realised his cum was starting to leak down and across her pussy.
"uh, Ang, I think you need to roll over, my um, it's leaking down, what if it gets inside you..."
"Here, hand me that towel" Mark rolled off of her she wiped her dirty pussy with the towel and then tucked in under her bum
"That'll work" he said.
"prrrrrrrrrrrpppppppppppppprrrrrrrrrrrrrrffffffffffffffttttttttttttttttttttttttttttt" a loud fart echoed now that her cheeks were tucked together.
"Sorry, I can't help it, ugh and I'm sorry it was so messy. I should have stopped you when I realised what was happening"
"No, not at all, don't be sorry about anything. You are amazing, it's kinda hot that I made you do that.."
"It is hot that you made me shit?"
"Well Julia made you , and fart, your farts are actually pretty sexy. And I don't know why, but it felt good sliding my cock through your shit, maybe it made it feel more like the real thing, I don't know"
"But what about the smell, I'm surprised it didn't turn you off"
"To be honest, I was so into the moment I didn't even notice, I don't even notice it now"
"Want to know what made me cum before you?" Ang asked, Mark nodded.
"I realised my brother was literally fucking the shit out of me"
Mark felt his cock twitch, it started to get hard again.
"Want to know what sent me over the edge? besides being inside you?" Mark asked, Ang smiled and nodded.
"It was when I saw that your hand was covered in shit, that you hard rubbed yourself off instead of stopping, that was it for me"
"Stopping? Oh I couldn't have stopped, I've wanted you inside me for so long.... um"
"So long? How long have you been thinking about this? Since before last weekend?" Mark propped himself up on his elbow, his cock was back at attention.
"I've thought about you a few times, you know when I've used my toy"
"Holy cow, I had no idea"
"Have you ever thought about doing things with me?"
"I'd be lying if I said no, you're a very attractive girl, I should go have a shower before all of my willpower is gone" Mark said as he rolled out of the bed.
"Really, you're going to leave an attractive, naked girl on her bed all by herself?"
"Damn it sis, you've gotta quit that, we're already going way past lines we shouldn't"
"Says you, I'll wear you down eventually big brother"
Mark shook his head and walked out of the room.
