It was a muggy August evening as Tyler sat on the couch flipping through the channels to find something worth watching. It was about 11pm, yet the temperature held steady at about 88 degrees with an equivalent dew point. Sweat was beading up on his youthful 19 year old body while he sat motionless. There was no air conditioning in the house because Tyler’s father was too cheap to pay for the extra electricity.

Tyler’s twin sister Taylor was laying on her back on the couch with him. Her head was on a pillow just to the side of Tyler’s leg and her feet with pink painted toenails were elevated on the arm rest of the couch. Taylor was wearing short running shorts and a tank top. Tyler was wearing only a pair of mesh gym shorts. Being twins, they had seen each other nude many times. But it had been at least ten years since the last time they were nude in front of each other.

“It’s too fucking hot!” yelled Taylor stomping her foot on the armrest, almost startling Tyler. “I know! And there’s nothing on fucking TV either!” replied Tyler. It was clear the heat was making them both quite moody. They had spent most of the summer together since their parents went away just about every weekend to their friends lake house in the mountains. This was the first summer back after their first year at college. Both Taylor and Tyler both went to the same school. Once they were on campus, they barely ever saw each other, so they seemed to be enjoying the time they spent together over the summer.

Taylor slowly rolled off the couch and stepped over their black lab Stout. “I’m going to bed” she muttered as she disappeared out of the light from the TV. “Night” replied Tyler.

After a few more minutes of flipping through channels, Tyler came across some soft core porn. Tyler was no prude, he was quite into porn and very interested in some kinky fetishes since regular porn didn’t get him off as much anymore. He decided that since he didn’t feel like moving that he’d give this a go. He lifted his ass off the couch and slid down his gym shorts so he was totally naked and slowly started stroking his cock. Tyler was a pretty muscular guy and had a pretty good size cock coming in at 7″ inches and thick. This sometimes proved to be an issue with some younger girls through the years as they were simply too tight to take his girth.

To his surprise he had worked up a pretty good hard on thanks to the lesbian scene on the screen. He was edging closer to blowing his load when out of nowhere Taylor yelled “what the fuck are you doing?!” Tyler quickly looked at the doorway to see Taylor standing just outside the room and he quickly scooped up his shorts throwing them over his massive throbbing cock creating a tipi. “What the fuck Taylor! I thought you went to bed!” Was all he could come back with.

Taylor slowly moved into the room and now Tyler could see that she was complete naked standing there. “I was headed to bed but couldn’t sleep so I decided to use your computer to use the Internet and rub one out” she replied. This was no shock to Tyler as they have always been open about talking about their sex lives and masturbation. What was starting to shock Tyler was the fact that Taylor kept walking toward him on the couch completely nude. As she finally made it to the couch and sat down next to him she playfully said “so, what’re you doing there?” meanwhile the scene on the TV had now changed to a threesome with a guy and two girls. “What the hell does it look like I’m doing? Why are you down here naked?” He asked. “Well, I was using your computer and I went to delete my browsing history and I saw that you hadn’t deleted what you had been looking at the past few days” she said. Shit. Thought Tyler in his head. I’ve been looking at some fucked up things lately. Scat, watersports, beastiality, incest… Before Tyler could say anything, Taylor had reached over and grabbed the top of the tent strung out over his cock from his shorts. She pulled away the shorts exposing his still hard throbbing cock. “What are you doing Taylor?!” He yelled. “Well, you like watching brother/sister videos, but something tells me they aren’t real, do you want the real thing?” Before he could even offer an answer, Taylor swung her head down and took his cock into her mouth. He felt as though he should be protesting, but he really didn’t want to. Taylor kept working his cock in her mouth from the side and she started to rub his balls in her fingers. She started moaning a primal moan of pleasure which made his cock grow what he felt like another inch.

Tyler started to caress her breasts. They weren’t very large breast, maybe somewhere between a B and C cup, but they were the most perky nipples he had ever encountered. Her nipples grew at the touch of his hand. Both of their sweaty sticky bodies were enjoying this too much to think of stopping.

Taylor stopped sucking her brothers cock for a moment and repositioned herself on her knees in front of Tyler between his legs. She continued her assault on his cock and was sure not to forget to lick and suck his balls every so often. Tyler couldn’t help but think that she had clearly had some experience doing this. In mid thought, Taylor let out a small squeal which gained back his attention. He could now see that Stout had gotten up and moved to lay down behind her. It was clear to him that he was licking at her pussy as she knelt there blowing him.

“Stout! Stop!” Yelled Tyler. Stout had no intention of stopping. “Don’t you want him to stop?” He asked. Taylor took his cock out her mouth and looked him in the eye “Isn’t this one of the things you like to watch online?” She had a devilish look in her eyes he had never seen before. Stout seemed to know what he was doing as it was within what seemed like seconds Taylor was screaming from her first orgasm. Stout was not stopping though so she jumped up to get away from him which landed her straddling over Tyler’s cock directly under her shaved pussy. We both starting kissing each other like mad lovers and she lowered herself and his cock easily slid inside with the help of her cum and the dog slobber.

As Taylor rode her brother Tyler’s cock, Stout started to lick the both of them as they fucked. He would lick Tyler’s balls, Taylor’s asshole and everything in between as they fucked. They kept this up for a few more minutes until Tyler said he was ready to cum and Taylor stopped and told him he couldn’t yet. She slipped of of him allowing his slimy cock to drop which allowed Stout to lick every inch he could cleaning the sex juices from him. This alone made Tyler feel as though he could cum still.

“What now?” Asked Taylor. Stout had finally taken a break and curled up and was licking his now protruding pink cock. “Umm, I wanna see you suck his cock.” Said Tyler. “Whoa, uhh, maybe if you do it too” she replied. “What?! You’re the girl, that’s what you do” was all Tyler could get out. “How about if you suck his cock, I’ll also suck it and then I’ll lick your asshole. If it’s clean” said Taylor. “OK!” Yelled Tyler almost as a reflex. He had always wanted his girlfriends to eat his asshole but was too afraid to ask, worrying they would think he was gay and spread rumors in school. “Well then, start sucking boy!”

Tyler got down on his knees and pushed Stout over on his back. Now he had a full clear view of his massive dog cock. It must have been 8 or 9 inches long and at the base he had two huge balls hanging to his asshole. He had never been neutered as part of one of dads classic get rich quick schemes that he planned on breeding him. “Well…” interrupted Taylor in the middle of his thoughts on how large this piece of cock meat was. Without a hesitation, Tyler put his lips over Stouts cock and slid it as far back as he could. Every couple of seconds small amounts of pre cum kept shooting down his throat occasionally causing him to gag until he got in rhythm with the shots and was swallowing each time. “Suck that dog cock!” said Taylor with a look of pure happiness on her face. Tyler knew she was sexually active, but never knew she was such a pervert. Tyler took a moment and let the dog cock pop out of his mouth “lick my asshole bitch!” he said as he also took a moment to catch his breath. Taylor rolled her eyes and moved around behind Tyler. He moved to his knees and put Stouts cock back in his mouth and pushed his ass into the air. Taylor got down and sat cross legged behind him. She slowly rubbed his ass cheeks and his balls all moving in towards the bullseye that was his asshole. Tyler was getting so turned on that he forgot he had a dog cock in his mouth and the first blow job he was giving was now almost as natural an action as breathing. What was turning him on even more was that he knew how sweaty and ripe he was down there. He had shit a couple times that day and since he was known to play with his ass, he’d often touch his asshole and smell his finger thorough out the day.

Taylor didn’t seem to mind Tyler’s ripe ass. With one swift motion she stuck out her tongue and buried it right into his ass cause him to jerk forward and take stouts cock deeper into his mouth. He was in heaven. His first rim job and it was his twin sisters tongue in his ass. She worked his ass for a good 10 minutes and got him relaxed enough to the point that her tongue was penetrating his anus at least an inch. She finished by licking from his balls all the way to the top of his ass crack a few times. She then crawled over on the other side of stout and gave him a devilish look.

“Your turn” said Tyler as he pushed Stouts cock in her direction. Without hesitation she took it and buried it in her mouth making the whole thing practically disappear. Tyler stood up to get off his knees for a minute and sat on the couch. He sat stoking his cock as he watched his sister blow the family dog.

“Do you wanna fuck him?” asked Tyler. Taylor had a look of puzzlement on her face before letting the dog cock pop out her mouth like a lolly pop and said “only if you clean me out after with your mouth”. With everything that had gone on so far, Tyler figured why the hell not. “OK, but not in here. Mom will kill us if we make a mess on her carpet. Let’s go out on the deck”. The secluded back yard came in handy for the debauchery that was happening. All three of them made their way out the sliding door and onto the wooden deck. The hot humid air actually felt refreshing in their naked bodies, maybe because of the sweat they had worked up. “Get on your knees and I’ll guide him in” whispered Tyler. Taylor obeyed and her round ass cheeks and beautifully shaven pussy and asshole were glistening in the moonlight. Without warning, stout mounted Taylor like he knew what he was doing already. Tyler didn’t even have to guide him in. Taylor began to pant and moan as Stout began his assault on her 19 year old pussy. Tyler moved around to in front of her and knelt down so that he could put his cock in her mouth. Taylor sucked his cock in unison with each thrust Stout pounded into her. In this position Tyler counted three orgasms he could tell his sister had. But she could have had many more for all he knew. Finally Tyler felt his orgasm starting to stir and without warning he blasted his load directly down his sisters throat. She took every drop without effort and proceeded to clean her brother’s cock of any stray drops.

“Owwwww” screamed Taylor. “What is it?” Asked Tyler. He just pushed it all the way in and it popped.” Taylor said with a shaky voice. “Don’t worry, he just knotted with you. I’ve seen it online. This happens to keep the cum in, we just can’t let him pull it out” he said. “If he’s gonna cum, you better get down there” Taylor reminded him of his end of the bargain. Without any protest, Tyler moved around behind Stout and Taylor and slid himself on his back between them so his face was directly under her doggy cock filled pussy. The whole time, Stout was still pounding into her.

“I think he’s coming. It’s so warm.” said Taylor. “Ok, once his knot goes down it’ll pop out” he educated her. Meanwhile Tyler decided to spend some time getting to know his sister better and started licking her clit. She was super sensitive and it took only a few moments for her to cum. She let out a scream as her teen pussy tightened around the pink dog cock. Some cum started to sneak by and Tyler was sure to start his clean up job. Before he knew it, with a pop sound Stouts cock shot out and a stream of dog cum came rushing out all over his face. He tried to catch as much as he could, but it was everywhere. Stout cleared out of the way and retreated to lick himself clean. Tyler sat up and Taylor turned to face him not realizing his face had gotten covered with the cum. She started laughing at the sight of his firmly closed cum covered eyes but then started licking as much as she could to help him. She licked his eye lids clean so he could open his eyes and worked her way to his mouth where they made out for a few minutes.

Neither of them wanted to move. They had so much fun, and didn’t want it to end. They both fell asleep naked on the deck, sweat and cum covered. They were woken to the licks of Stout as the early morning sun rose. The both laid awake watching the sun rise through the trees before getting up and showering before their parents would be back home. Both Taylor and Tyler knew this would not be a one time event.

This is my first story. If people like it I’ll write more.
