If, however, you enjoy the idea of insanely perverted siblings acting out their darkest fantasies on each other, please continue reading. This story is reserved for the most depraved of you out there. Tim drunkenly climbed the stairs of his parents' home up to his old bedroom. He smiled to himself, imagining what waited for him there. He slowly pushed open the squeaking door and stumbled inside. It was a humid summer night and the air in the bedroom felt hot and thick on his skin. He took off his shirt and tossed it near the foot of his bed. Then he looked to the other side of the room. His sister Lori was sound asleep in her bed. She was lying on her stomach on top of her covers. Her big, round ass, barely protected by her skimpy panties, was out in the open, just begging for Tim to take a peek. Nights like these had always been Tim's favorite growing up. He hated the heat, but loved what it brought. When the weather got like this, his sister always stopped wearing pajamas, choosing instead to sleep in just her panties and a short t-shirt. Tim reached his hand into his jeans and wrapped his fingers around his growing cock. He devoured his sister's body with his eyes and began stroking himself. The fact that Tim and Lori shared a bedroom had never been a concern for their parents. They lived in a relatively small house and just didn't have the space for both of them to have their own rooms. So, when both of them suddenly needed a place to stay for the summer, it seemed natural that they would share their old room again. Lori was back at home because she had no place else to go at the moment. After graduating high school, she had met an already successful guy and married him quickly. Her life was pretty much set. She had a wealthy husband, a nice house, and even a maid to clean the place. However, Lori discovered that her husband was sleeping around with several other women, most notoriously her best friend Tracy. So, with no job, no college education, and no real skills to speak of, Lori was forced to move back in with her parents. Tim, who was two years younger than his sister, was in his third year of college. When summer break came around, he moved back home as he had done every other year. What he did not expect to find was that his sister was also staying at home. He played it off like it was no big deal, but Tim couldn't have been happier. Sharing a room with his older sister had always offered Tim opportunities while growing up that he might not have found otherwise. His parents might not have realized it, but having a hormone-filled, perverted teenage boy share a bedroom with a teenage girl is never a great idea, even if they are siblings. Tim was possibly one of the worst brothers on the planet, yet no one was the wiser. He had always secretly lusted after his sister, and sharing the same room as her was too tempting for him. At night, he would often lie awake and listen to Lori masturbating on the other side of the room. She had always been quite the lusty girl herself, and inadvertently provided her brother with a large collection of spank material, thinking she was being sneaky about it. Tim would frequently raid his sister's panty drawer, jacking off into the soft material. Sometimes, he would find used pairs in her clothes hamper and sniff them. The smell of his sister's pussy would fill his nostrils as he tugged one out. With the webcam on his computer, he would often catch Lori changing. Sometimes, if he was lucky, he would get some footage of her using one of her sex toys. Tim had long ago discovered Lori's arsenal of dildos hidden in a box beneath her bed. She had all shapes and sizes. There were realistic rubber dildos, powerful vibrators, and even a small butt plug. Tim truly was a perverted little fucker. But, all of that was child's play compared to what he did when Lori was asleep. One day, Tim discovered that Lori was a very heavy sleeper. Even shaking her a bit wasn't enough to wake her up. Tim, in a daring bit of depravity, took advantage of this fact. He would wait in his bed until Lori was fast asleep. Then, after building up a sizable amount of courage, he would go over to his sister's bed and nudge her to test that she was asleep. Then the fun would begin. Tim would pull back her clothes and touch her naked body. He would cup her tits in his hand, run his hands all over her ass, and rub his cock wherever he pleased. He was always extremely cautious, taking things as slow as possible, but she never even stirred. A few times, he even slid a finger along her pussy lips. He never dared to actually stick a finger inside though. There was an indescribable feeling that Tim experienced each time he molested his sister this way. The danger of her waking up got his blood flowing quickly. The fact that she had no idea what he was doing to her excited him beyond anything else he had ever experienced. Lori's big butt was Tim's favorite. He usually spent the most time caressing her soft ass with his hands. He would grab big handfuls of her cheeks and shake them slightly. Watching her ass jiggle was usually enough to send him over the edge. Then he would shoot his load onto his sleeping sister. He would aim his warm cum across her ass, the back of her legs, her perky tits, her face, really wherever he felt like. Even with a facial of her brother's cum, Lori wouldn't wake up. She would just continue to snooze away while Tim pulled his pants back up and climbed back into his own bed. Come morning, the cum would spread out or dry up enough that Lori assumed she had been sweating or drooling. Tim always got away scott free. So, quite drunk and already sweating from the humid air, Tim completely disrobed and stood next to his sister's bed. He looked down at her, growing excited by the second. He had never done this while drunk, and the booze was dulling his usual cautious approach. Lori was lying in front of him, ready to be used however he wished. She was a fairly short girl, with light blonde hair that reflected the moonlight coming through the window. Tim loved her body; how her waist was small, yet her hips were wide. Tim looked down at her round ass. He loved when Lori would fall asleep on her stomach because that offered him the best view of her luscious butt. Tim knew instantly that that's where he wanted to cum. He wanted to shower Lori's ass with hot cum. So, he reached down and grabbed ahold of Lori's tiny panties and began working them down her legs. He peeled the tiny garment over her hips, out of the crack of her ass, and all the way down to her knees. It astounded him that she would wear something so revealing while they shared a room together. She really is just begging for it, thought Tim. With her panties down, Lori was completely exposed. Tim then climbed up onto the bed, straddling the backs of Lori's legs. He grabbed his hard cock in his hand and reached out to touch Lori with the other. His hand made contact with her soft skin and he slowly began rubbing her ass. Normally, Tim would not be moving so quickly or rashly, but he was quite drunk and wanted nothing more than to cum on his sister's ass. Caution wasn't one of his priorities. Tim slipped a finger into the crack of Lori's ass and slid it up the length of it. There was a steamy warmth emanating from between her legs. In the moonlight, Tim could see Lori's pussy partially hidden between her legs. He bent down close to it to get a better look. He moved so close that he could feel the heat coming off of it wash across his face. Lori's scent filled his nostrils, driving him mad with even more lust. As he looked at his sister's neatly trimmed pussy, Tim thought that she looked good enough to eat right then and there. Then an idea popped into his head. In all the time he had been doing this, he had never once used his tongue on her. He had wanted to, but never dared to actually do it. But, with help from his new liquid courage, Tim stuck out his tongue and got his first taste of his sister. She was sweeter than he expected. He had licked out the crotch of her used panties before, but nothing could compare to the real thing. He licked greedily, not stopping at just her pussy. He licked all over. Soon, he was licking the big ass cheeks he had always worshipped. When he reached the crack of her ass, Tim stopped. He spread Lori's ass open and looked down at her tight, puckered asshole. He had never licked a girl's asshole before, and wasn't sure about it. Then the booze took over. Fuck it, he thought, no one's going to know anyways. With that, he pressed his face into her ass and began lapping at her hole. Tim was thoroughly enjoying himself. His head was surrounded with his beautiful sister's ass, he was licking her tight hole, and he was about to cum. Oh shit, he thought, I'm about to cum. He hadn't planned on cumming so soon, but he must have gotten more caught up in what he was doing than he had realized and stroked himself too much. He straightened himself up, still on his knees and straddling Lori's legs. After having his face buried in Lori's hot butt, the humid air actually felt cool on his skin. Tim aimed his cock downwards and bucked his hips forward as he began to shoot a huge load. The hot cum rained down, covering Lori's ass. It felt as though Tim was going to cum forever, but, finally, the last of his orgasm surged through his body and he regained control over his muscles. He looked down at his sister's ass, drenched with his hot cum. There was a stillness in the air and Tim didn't move. He had been reckless and he knew it. He shouldn't have let his body control him. With the way he had been touching and licking Lori tonight, he could have easily woken her up. Why hadn't he just pulled her pants down and jerked off onto her ass like he normally did? Tim craned his neck to look up towards Lori's face. It seemed his moment of worry was for nothing though. Lori's eyes remained closed and she never even stirred. Tim exhaled in relief. He had gotten away with more than he usually did. He climbed off of the bed and reached down for his pants. But, he suddenly felt quite dizzy from the alcohol. He stumbled a few steps and decided to lay down on his bed for a minute while he got his bearings. Just for a moment. That's all he needed. Just to lie down for a moment. Maybe he would close his eyes to keep the room from spinning. Just a moment or so to get his bearings. Just a.... Tim passed out on his bed. His digital alarm clock read 3:06 am. Tim woke up face down on his bed. Lori was shaking his shoulder, trying to wake him up. "Hey," said Lori in a sweet tone. "Hey, Tim. Wake up." Tim's eyes blinked until Lori's face came into focus. She was kneeling next to his bed. "Uuugggh. What?" said Tim disoriented. "Tim, wake up. Did you go out and get drunk with your friends tonight?" "Wha- what? What time is it?" "It's four o'clock." Tim looked around the room. Had he really slept until four? The day was practically over and he hadn't even gotten out of bed. But, a few things suddenly occurred to Tim. First, he still felt pretty drunk. Secondly, it was still dark in the room. He glanced at his alarm clock. The red letters said 4:03 am. Tim snapped back into consciousness as he realized that only an hour ago he had cum on his sister and then passed out naked on his bed. He tried to sit up, but something was holding him down. He was tied down to his bed. All of his arms and legs were tied to a different bedpost by thick ropes. His stomach was flat against his bed sheets and he couldn't move. "You know what I did tonight?" said Lori. "I read a book and went to bed early. So, my night wasn't exactly as exciting as yours was.... That is, until I woke up in the middle of the night with my panties down around my knees and something wet all over my ass." Tim frantically looked around, trying to find a way to break loose of his restraints. But, it was no use. He was face down on his mattress completely naked and the ropes were holding tight. "Don't bother trying to break free," continued Lori as if she were a super villain revealing her ultimate plan. "I tie a pretty good knot. Anyways, back to my night. Now, I was naturally perplexed at how I had ended up like this. That is, until I looked across the room and saw my pervy little brother passed out naked on his bed with his pants in a heap over on my side of the room. That's about the time when I went into the bathroom to look at what was now running down the crack of my ass a little more closely, and, wouldn't you know it, I was covered in cum." "Lori, please. I can explain," said Tim quickly. "No. No, I don't think that's necessary," said Lori. "Actually, I don't want you to ever try to explain your sick brain to me. Ever." Lori stood up and Tim was surprised to see that she was completely naked. "In fact, I think you should just stop talking altogether." In Lori's right hand, she held a red ball-gag. She stuffed it into Tim's protesting mouth and tied the straps tight around the back of his head. Tim continued to plead with Lori, trying to explain, but his pleas were muffled by the gag. "I don't know what all you did to me," said Lori, "but I have a feeling that this will make us even. Lori picked up a strap-on from off of the ground and began slipping into it. Upon seeing it, Tim couldn't even process what it was for. He didn't even know that his sister owned a strap-on. Then he realized the position he was in; face down, tied up, legs spread apart. Lori was going to fuck him up the ass. He screamed into the ball gag, but only a pitiful sound came out. Lori smiled and continued putting on her strap-on. The dildo sticking out of it was a large, flesh colored cock about nine inches long. Veins bulged in the firm rubber material and the head stood large and proud at the end of it. On the inside of the strap-on, there was another smaller dildo which slid inside of Lori's pussy. She let out a soft moan as she inserted it then began tying the straps tight. "I think I'm going to enjoy this," said Lori and moved behind Tim. She grabbed a big bottle of anal lube and climbed up onto the bed. Tim moved his head from side to side to try and look behind him. He had never been more scared of his older sister. When the fuck did she get into stuff like this? Lori began coating the big dildo with lube, making sure it was properly greased up for anal penetration. She had already lubed up Tim's ass while he was passed out. "Now, you better learn how to relax your ass right now, or else this is going to be very uncomfortable for you," said Lori. With that, she firmly pressed the tip of her dildo against Tim's puckered asshole. It met resistance, but Lori forced the tip inside. Tim cried out as his ass was suddenly penetrated. Lori smiled. But, she spared no time and pushed more of the dildo inside. Tim clenched his ass tight in reflex. This just made it hurt more, so he concentrated on relaxing it. This was not so easy as Lori began thrusting in and out. He cried out a few more times. "Better be quiet, bro," said Lori. "Wouldn't want Mom and Dad to come up here right now, would you?" Tim stifled another cry. She was right. He didn't want that. There's no way to explain something like this to your own parents. Lori pulled all the way out of Tim's ass and slicked the dildo up with even more lube. Then she shoved it back in. After a few minutes, Tim finally began to relax his ass. "Ahh, that's better," said Lori. "Yeah, just let go and take it like a little bitch." It may have hurt less now, but Lori found a way for it to be more humiliating than before. But, given his options, Tim thought he would be better off with a relaxed asshole, even if that made it feel like he was now accepting the fucking. Lori picked up speed and began fucking Tim harder. He whimpered into the ball gag as she mercilessly began to pound him. Lori's hips slapped against her little brother's ass again and again, forcing the big dildo deep inside. Tim was still trying to adjust to the rubber dong inside of him. It felt unnatural for a cock to be inside of him. He felt like he had to shit, but couldn't. Also, it still hurt, but he was beginning to become accustomed to that. Lori, on the other hand, was enjoying herself immensely. The dildo on the inside of the strap-on was hitting her at just the right angle and there was a wonderful sensation on her clit each time her body slapped against Tim's. "Are you enjoying yourself, Tim?" she said. Tim answered in garbled words. "Because I feel fantastic. I think I might even cum soon." Lori braced herself to get more leverage and began pounding Tim even harder. "You know, if there's one thing we've got in common, we've both got great asses. But, I think yours is much more fun to fuck." Lori moaned through gritted teeth in pleasure. It wasn't just the dildo in her pussy that was getting her off. More than anything, it was humiliating Tim that was really bringing her close to orgasm. Lori untied the ball gag and tossed it on the floor. Tim gasped for air and immediately resumed pleading. "Lori, please stop. Please." "Shut up, bitch. I'm almost done," answered Lori. "Now, say you're a little pervert." "Lori, please. Please stop." "Wrong answer," said Lori. She thrust into Tim hard, burying the dildo as deep as she could manage. "AAAAHHH!" squealed Tim. "Do it. Say you're a little pervert." The last of whatever fight Tim still had in him suddenly faded. "I... I'm a little pervert." "Good," said Lori and she resumed fucking him at a more manageable pace. "Now, tell me how much you want to fuck your older sister." "I want to fuck you," obeyed Tim. "I want to fuck you so badly, Lori." Tears began to stream down his face, more out of humiliation than anything else. "Oh yeah. Now beg me to fuck you with my cock." "Wha- no. Lori don't...." Tim was interrupted by another massive thrust from Lori. He suppressed another yelp and gave in yet again. "Ok! Ok. Please fuck me." "Louder," said Lori. "Please fu...." "Louder!" said Lori. "Please fuck me with your big cock!" said Tim. "With pleasure," said Lori. She grabbed the back of Tim's head and forced his face down into his pillow as she began a merciless pounding of Tim's ass. She was giving him all she had, making sure to destroy his tight hole. Lori was swimming in ecstasy. Her pussy ignited in pleasure and she felt an orgasm begin to sweep over her body. She reached behind herself and stuck her middle finger deep inside her own asshole, enhancing the orgasms power. It rocked her body as wave after wave crashed into her. "Oh yes! Fuck yes! Fuuuuuuuck me!" said Lori as she continued to ravish Tim. His muffled cries were like music to her, and she was the conductor. She suddenly felt weak and collapsed forward on top of her brother. Her firm breasts pressed against the bare skin of his back as she continued to down into him. Tim had by no means grown comfortable with the situation, but feeling his sister's body rubbing on top of him, combined with the forced stimulation of his prostate, gave him an erection that he couldn't begin to explain. As her orgasm subsided, Lori finally lay still. Tim grew silent as well, and the two of them breathed deeply as the adrenaline levels began to diminish. Lori slid her dildo out of Tim's ass and he groaned from the sensation. Tim turned his head and watched Lori take off her strap-on. Then she walked over to her desk and clicked a button on her computer. The monitor turned on and he could see the image of himself tied to his bed looking back at him. Lori had recorded the whole thing. She rewound the footage a minute or so to test the video quality. She hit play and Tim saw himself getting dominated by his sister. Lori's big ass shook each time she thrust herself into him, and Tim couldn't help but be turned on at how hot she looked while doing it. Heavy Sleeper His eyes widened as he quickly realized how serious this video could be for him. Lori smiled down at Tim. She didn't even have to explain the power she had over him now. She saw in his eyes that he understood. Lori picked up the panties she had been wearing earlier and walked back over to Tim. "Here," she said. "You might as well have these." She stuffed the dirty panties into Tim's mouth. They tasted strange on his tongue and they were slightly wet. "I mopped up the cum on my ass using these earlier," said Lori. "If you spit them out, I'll put the strap-on back on. Don't ever fuck with me again."
