All characters in the story are eighteen or older. Thanks for all the feedback and suggestions I got on the board and in the comments field. You've made the story a lot better. This story contains incest. * "It's only fucking pot, dad. You're so fucking unfair!" Sarah screamed and with the door open he could finally hear the words. Mark woke up from the screaming downstairs and he immediately knew what it was. He looked over at the clock and could see it was well past her curfew and she was most likely drunk, too. Mark waited for it to calm down so he could go back to sleep again, but it seemed worse than usual. "Only pot? If you're not careful, you're going to end up in the gutters. Why can't you be more like your brother? More responsible!" their father screamed back at her. "Twenty-one, a virgin and still living at home with his parents. No, thanks, dad, I would rather live my life in the real world than in front of the computer!" Sarah screamed back at him and Mark wished he hadn't heard it. He was already felt pathetic for his lack of experience and hearing his sister give voice to what he already felt only made it worse. Mark was everything his sister wasn't. A good student; he didn't go out partying and yes, he was still a virgin. He had thought things would've changed when he started studying at the local college, but it hadn't and he still felt as awkward around women as he had in high school. His sister Sarah was eighteen and all she had to do to get laid was to wiggle her butt and all the guys would come running. She had probably already slept with more people than he would in his whole lifetime and it was killing him. With her long blonde hair, firm butt and perfect perky tits she was every man's dream. Of course their parents saw him as the successful one, with good grades and well on his way to get a degree in computer science. It wasn't like Sarah was going to fail to graduate; she only had three months left of her senior year and had done okay so far. On the other hand she had been even more antisocial than normal lately, and he couldn't remember the last time he had a conversation that lasted more than a few words with her. They continued screaming at each other and even his mother got involved until he could finally hear Sarah make her way up the stairs and slam the door behind her. Tomorrow morning was going to be tense and Mark didn't look forward to it. He wished he had a friend he could call and hang out with tomorrow, instead of being stuck in the house. Playing video games, watching porn and studying was his life was and he hated it. It wasn't fair. The tension in the morning was even worse than Mark had feared the day before and he understood why when he heard about the punishment. Sarah was grounded for the rest of the semester and she wouldn't be allowed to go to the senior prom. They were going to drop her off at school and pick her up after her last class. She wasn't allowed to meet any of her friends after school until she graduated. Sarah didn't say a word to their parents during the whole day and only a few words the next few days. She didn't say much to Mark either until a week later when she entered his room. "Hey, Mark," Sarah said and he knew she wanted something from him. It wasn't hard to figure out since those were the only times she really talked to him. "What do you want?" Mark asked, curious about what she would ask for this time. Of course there was always the chance that she was lonely and wanted someone to hang out with, but Mark didn't think so. She looked pretty nervous as she walked into the room and he didn't know why. She usually always got what she wanted and even he had problems saying no to her. It was something about her blue eyes and she was still his baby sister and he loved her despite all her flaws. "Why do you think I want something? Maybe I just want to hang out with my big brother," Sarah said and sat down on the bed as the only chair in the room was the one Mark sat on. Mark could see her tanned legs dangling a back and forth. She didn't work out, but it was impossible to tell. Her eyes were long and thin and he caught himself staring at them. Sarah was pretty and she knew she was and always used it to her advantage. She and his mom were the only girls who entered his room and once more he became aware just how much he wanted to have sex. Just do with any girl so he could get it over with. For a second he wondered how she would react if he pushed her down on the bed and removed her clothes. She didn't say anything and neither did Mark until he the silence started to kill him. "Do you want to play some video games?" Mark asked even though he knew how little interest she had in video games, but it was all he came up with. The annoyed look on Sarah's face made him regret even asking the question. Why was it always so difficult with her? They had gotten along fine until she started high school, and then not so much. A part of him suspected it was because didn't want people to know he was her brother. He wondered if she still was ashamed of him. He could see how Sarah took a couple of deep breaths. She had a determined look on her face and he was finally going to find out what she wanted. At least this time she had tried to do some small talk before spilling it out. "Look, Mark, I'm going to be honest, but first you have to promise not to tell our parents. Pinky swear," Sarah said, sounding very serious. Again he wondered what she was about to ask. He had never told on her before, so he didn't really understood what she was worried he would tell this time. It also made him more curious and he moved over to the bed and stuck out his pinky finger which she quickly intertwined with hers. "I promise I won't tell," Mark said and he saw how Sarah immediately felt more relaxed. "I won't talk with you ever again if you tell...Okay...Here's the thing; you know why I got grounded, right?" Sarah began and she didn't continue until Mark nodded. "I've been feeling really bad this week and I'm lonely and I can't talk to any of my friends since mom and dad got my phone. I'm going crazy, Mark, and... I just really need a joint. Just one to relax my nerves," Sarah said, begging him. "No way, Sarah, there's no fucking way. There's no way I'm going to help you get drugs," Mark angrily answered and he started to feel worried about her. She must really be desperate if she wanted him to get drugs for her. "Come on please, Mark," she begged him and looked at him with her big blue eyes that were so hard to turn down. "I can't do that, I'm worried for you. What if you're an addict?" Mark voiced his concerns and he saw Sarah's trying to think up a plan. It was clear that she wasn't about to give up. "First I'm not an addict, I just like to smoke some pot and since I'm stuck here with nothing to do I deserve some fun. Why do you always have to be... never mind. What if I could get you laid? I know how desperate you must be, spending all these lonely nights wanking in front of the computer watching porn. If you help me out, I can set you up with one of my sluttiest friends..." Sarah said and Mark felt tempted by her proposal. He knew how hot some of her friends were and he would be happy to sleep with any of them. She was right. He wanted to experience the real thing, but how could he be sure that her friend would sleep with him? "I don't know, Sarah," he answered and even he could hear how close he was to giving in to his sister's request. "I guarantee that Lisa will sleep with you. She sleeps with anyone who shows her some attention and if I encourage her a bit, I can guarantee it will happen. Also I've seen her sleep with much uglier guys than you. If you just did something about the hair and put on a nice shirt you would even look half decent," Sarah said sounding more and more confident as she saw how Mark was giving in. "Fuck, I can't believe I'm doing this. Can you really guarantee it?" He felt bad how easy he gave in and let his libido take the decision for him. "I guarantee it, now if you just let me borrow your phone, so I can call her now and set it up." "What does she look like?" Mark asked. He knew it was wrong, but at this point he just wanted to get laid. This was the best shot he had in years. Mark didn't think she was lying and he knew most of her friends were just as slutty as Sarah. He felt his sister's hand squeezing his thigh. "Oh, she's very pretty: Long dark hair with a fit body and a nice ass. She makes me wet just thinking about her and I'm not even into girls... I can show you how she looks on Facebook later, but first I want you to hand over your phone, Mark." He didn't want to think about his sister getting wet, but with her hand on his thigh and the way she said had turned him on a bit. If she really was as hot as his sister said, he would do a lot more than buy pot to get a chance to sleep with her. He knew it was wrong, but he had no problems handing over the phone to Sarah. After all it was just pot. "I'm just gonna call my dealer really quick first," Sarah said as she dialed the number. She had the number in her head Mark wondered just how many times she had used it. It was too late to back out now and he didn't want to either. He wanted to have sex more than anything else and if it meant buying pot for his little sister, then so be it. He listened to his sister talk patiently, while he studied the way she looked. She had long hair now, it wasn't her natural hair color but it looked good on her. Of course she had looked just as good as a brunette. She had nice firm breasts. They were a bit on the smaller side but he doubted anyone complained. Sarah was a looker and she could be very charming when she wanted too. Once she finished the call she turned to her brother once more and handed him some money. "This should be enough; all you need to do is go pick it up at his place." "Eh, what about Lisa?" Mark asked, not too keen about picking up her pot without any insurance. He still trusted her to uphold the deal, but he had some doubts. "Oh, yeah, I don't remember her number. I'll just use your computer to contact her while you're gone. It will be all set up once you're back. I promise." Sarah said and he knew he was screwed. "Come on, Sarah," he said trying to put up some resistance. He didn't want her to use his computer, but he didn't know how he would be able to turn her down either. "Hey, you already promised to buy me pot, letting me us the computer for an hour is nothing compared to that. Besides do you want to get laid or not, 'cause I can cancel the whole thing if you want to." "Fine," he said, annoyed that somehow she had had become the one in power again. She knew how much he wanted to get laid and used it against him. At least once the date was set up he would be free once more. If he was lucky it would lead to more than a onetime thing. He cursed at how weak he was as he got up and waved a lackluster good-bye to his sister. She was too busy staring at the computer to care. Mark had his own car he used to drive to school. The address was on the other side of town and he wondered if his sister hadn't set him up, so she could have more time in front of the computer. There wasn't much he could do about it, at least it wasn't in the worst neighborhood in town. It took him thirty minutes to find the place and he felt nervous when he walked up the stairs to the apartment. The guy who opened the apartment was older than Mark was and he looked scary. "I'm here to meet Leon. My sister called and..." Mark said, sounding just as unsecure as he felt. "Ahh, little Miss Sarah's brother. Come on in," the man said and Mark followed him inside. There was stuff everywhere, a couple of guys sat in the sofa and smoked weed. One of them even offered Mark to try but he politely declined and soon they were all calling him a narc and laughed at him. He wanted to get out as quickly as possible, not comfortable with the situation. Luckily Leon wasn't interested in having him around either. Leon handed over the bag and Mark hoped that he wasn't getting ripped off. "Tell Sarah I miss her," Leon said to Mark when he left. Mark nodded in response. He had no real intention of telling his sister. Leon was not the kind of guy he wanted her to hang out with. He did this to get laid. He felt bad about what he was doing, but he didn't have any other options unless he wanted to stay a virgin forever. It was too late to back out anyway. Once he got what he wanted, it would be worth it. It had better be anyway, if not he would regret ever doing this. This was by the worst thing he had done, but he didn't feel weighed down by it. It felt liberating breaking the rules for once. It wasn't something Mark was used to. He could hear Sarah's voice coming from his bedroom when he got home. It was his room, but he still felt the need to knock on the door before entering. "Yeah, yeah, he's back now so I gotta go. Love ya," Sarah said to the person she was talking to. Hopefully it had been Lisa but he couldn't be sure. "So, Mark, do you have my weed?" Sarah said now turned towards him, sitting in a commanding pose. He was about to turn the weed over, before he realized that he would lose all power if he did. "Have you set me up with your friend yet?" "It's next Saturday. Try not to act like a dork, you have to cut your hair and you really need to buy a new shirt, Mark, and make sure you don't act too meekly. Lisa's mom works the night shift and the dad is out of the picture, so you will have the place all to yourself." Sarah said and she actually sounded supportive. It was enough to convince Mark to give her the bag of weed. "Thanks, Sarah," Mark said. Sarah get up from the chair with the first smile he had seen on her face since she'd been grounded and it made him feel nervous. "The date is actually in two weeks and on a Tuesday. Sorry," Sarah said and now it was more of a grin than a smile, but he didn't know what he could do about. At least it was this month and he didn't care if it was on a Tuesday as long as he got laid. Mark didn't like being lied to, but as long as he got the opportunity to sleep with her friend he could take it on the chin. "Hey, what does she really look like Sarah?" he shouted after her and she turned around. "I didn't lie about her looks and her parents won't be home. You won't be disappointed, I promise," Sarah said before she continued into her room, obviously eager to try out the pot. As long as she was at least somewhat attractive it would be enough. It irritated him that she left before showing hat Lisa looked like and it irritated him that she had lied. Then it hit him, his parents were going to see a play next week and it could very well be the same Tuesday she was sending him out on his date. Mark wouldn't let her back out of Sarah promise no matter what and he needed to tell it to her face. She had already started rolling the joint and looked up worriedly until she saw who it was. "I'm not going to let you back out of this promise. If you don't pay up..." "Don't worry, you will lose your virginity next Tuesday, Mark," Sarah said to reassure him and he felt more at ease again. "You better. Is this the same Tuesday mom and dad are going to see that play?" Mark asked, wondering if maybe she was just setting him up, so she could be home alone. "Maybe it is. Listen Mark, you have to decide if it's more important to do what our parents want or what you want. Lisa is a real slut, Mark, and she will fuck you in every way possible until you can't take it anymore, but if you want to stay home..." Mark groaned, knowing he couldn't back out. She was right; he really wanted to have sex. He gave her one last look before heading back to his own room. The next week went slow and he had a hard time concentrating on his studies. His mind kept drifting to what would happen with Lisa. He didn't talk much to Sarah and every time he went by her room he could smell the marijuana. If his parents hadn't been so naïve they would've smelt it too. He felt a bit bad, but she probably would've gotten her hands on it anyway. At least this way he got something out of it. It was still wrong, but there wasn't going to be a next time; Mark thought in an effort to comfort himself. The week after went even slower and he counted down the hours until the date. He followed his sister's advice and he cut his hair, bought a couple of new shirts and a package of condoms. When the Tuesday came he was more than ready. The same Tuesday his parents were going to the play. He didn't like lying to them, but it was something he had to do. He promised them to make sure she didn't sneak out or brought any friends over: all to keep their parents happy. Nothing was going to ruin this night for him. "You actually look half-decent for once, Mark. Good luck," Sarah said. She helped him with the last preparations before he was leaving. She even showed him a picture of Lisa and she looked really hot. She had super big smile in the picture. "She will sleep with me, right?" Mark asked, still feeling nervous about the whole thing. He didn't know what he would do if it didn't work out. He had done things he wasn't proud of to make it happen, but as long as Lisa slept with him it would be worth it. "Guarantee it," Sarah said, reassuring him and he started to feel better again. It was really happening. He was still nervous and his palms were sweating, but tonight it was really going to happen for him. After tonight he wouldn't be virgin. He wouldn't have to feel pathetic about his lack of experience anymore. Tonight was the night he was becoming a man. Mark felt good. He liked his new haircut and he felt that the new clothes looked good on him. His palms felt sweaty, his knees weak and his arms heavy. He got behind the wheels and took a deep breath before turning on the ignition. This was really it. So many thoughts were running through his head as he made his way over to pick her up. What would they talk about? Would she like the restaurant? Should he wait until the end of the evening to kiss her? Mark didn't know and it made him nervous, but Sarah had guaranteed it. He wasn't sure if it made him more nervous or not. On the one hand he didn't have to worry about getting it or not. On the other hand he felt really nervous about actually having sex. What if she didn't like it? Mark took another deep breath and parked the car, another deep breath as he walked up to the door and one last before he rang the doorbell. He couldn't remember the last time he'd been this nervous. Lisa took her time and Mark started to get irritated and for a second he wondered if anyone was home, before the door opened. "So you must be Mike. Let's get this over with," Lisa said. She wasn't dressed up, just a top and a pair of jeans, She didn't seem too eager to go on this date. She even got his name wrong, but it didn't matter to Mark as long she slept with him. Her attitude may be a bit off, but her looks more than compensated for it. "It's Mark actually, nice to meet you, Lisa," Mark said and held out his hand to greet her, but she ignored it and walked passed him after locking the door. "So, where are you taking me...Mark?" Lisa didn't sound very enthusiastic, but at least she got the name right this time. "An Italian restaurant that is supposed to be really nice," Mark answered. He had checked some online reviews beforehand and this had seemed like the best choice. "I like Italian," Lisa said, finally showing some interest. They walked over to the car and he held the door open to her. The ride to the restaurant felt really long as Mark didn't know what to say and Lisa mostly looked out the window. Her legs looked good even under the jeans and he wished he had the gut to move his hand over to them. He had expected her to show some interest, she hadn't even looked at him since she got in the car. Doubts started to enter his mind, if she really planned to sleep with him. His sister had guaranteed it and giving up already would be stupid. But when he saw Lisa pick up her phone and started playing with it, some of his hope died and was replaced by anger. Mark squeezed the steering wheel so tightly that his knuckles were getting white. It started to feel like his sister was actually tricking him. Dealing with Sister When Mark pulled into the parking lot, Lisa hadn't looked up from her phone once, Mark felt really irritated and took out some of the frustration on the car door as he slammed it shut. It caught the attention of Lisa who reluctantly got out of the car, still with her face glued to the phone. She was walking irritatingly slow, before coming to a complete halt as the phone rang. "I have to take this," Lisa said and made a motion for Mark to give her some privacy. "Wait for me inside. I'll be right there." Mark didn't know what to do, but when he saw her walk around the corner he decided to follow her. He needed to find out if she had any plans to sleep with him or if she was a distraction so Sarah could have the house to herself for a couple of hours. Mark knew he was taking a risk when he walked closer, but he had to know. The anger boiled inside him and it was only going to get worse until he could find out the truth. He had sacrificed so much for this opportunity. If it turned out he had done it all for nothing he didn't know what he would do, except to make Sarah pay for it somehow. "Uh-huh, yeah I know...I'll be there as soon as I'm done entertaining Sarah's brother...I want to see you too," Lisa said and Mark felt the tension rising inside him. He still didn't have a clear answer, but he was listening more attentively than he ever had for one. "It will only be a couple of hours...Haha, no, he's no threat to you. Haven't I told you about Sarah's brother?... Really? Well he's still living at home...21...At least according to Sarah...There's no way I'm going to let him touch me. I'm going to eat really slowly, until enough time has passed for Sarah to be happy..." Mark had suspect it ever since Lisa got in the car, but to hear it out loud and know it all been a trick was crushing him. He was shaking in anger and it was all directed at his sister. She had toyed with his emotions for her own benefits. Sarah didn't care about him or his feeling. If she did she wouldn't have done this to him. He felt betrayed and he wasn't going to let her get away with this. He didn't know what he wanted to do to her, but it had to be something just as horrible as she'd done to him. The whole date had been a sham. Everything she'd said had been a lie. He had never felt so angry and betrayed in his life and he didn't want to part of this sham anymore. Mark walked towards the car with the determined steps and he heard Lisa scream the moment he got inside the car. "Wait Mark...Fuck!" she screamed before her voice got muffled by the closed door. Mark was done listening to any more lies. He didn't want to hear what she had to say. He had never been so humiliated and it was all because of his sister and her selfishness. He saw how Lisa threw out her arms in the rear-view window as he set off from the parking lot at full speed. Mark got angrier and angrier as he riled himself up during the ride home and the angrier he got the faster he went. There was something liberating about stepping on the gas pedal and ignoring all the rules. It didn't make him any less angry, but it made him smile. He didn't know how Lisa would get home and he didn't care. It was Sarah's fault anyway, everything was her fault. He must've missed what a bitch she was, because she was his sister. Sarah had looked at him at one point, but maybe that had been a lie too. Now she probably saw him as a pathetic little loser. Mark had to use the whole road to make it through the corners going without going off and by some miracle he made it home in one piece. The first thing he spotted on the driveway was an unfamiliar car and now he knew his sister didn't give damn about his feelings. He felt like a complete for even believing her in the first place. She was just another junkie that didn't deserve to be trusted. Well, if he wasn't going to get laid tonight, then neither was she. He parked the car and made his way to the front door. The door was unlocked and once he opened it he could hear the sound of his sister's moans. "Oh god, I've haven't been fucked since they grounded me. I need that cock inside me," Sarah called out to the guy she was with. The sounds came from the living room and it didn't appear like they had heard him. If there had been any justice in the world it would've been Lisa calling out to him to fuck her and not this. Sarah wanted to get fuck badly, but there was no way Mark was going to let her get it. Not after what she let him go through. The first thing he saw when he entered the living room was the naked ass of a guy lying on top of his sister and something snapped within him. It had too much and seeing some guy about to fuck his asshole sister was too much. "Get out! Get the fuck out of here," Mark screamed while he closed the distance and kicked the guy so he fell over. The feeling of power as he watched the terrified look of the guy scrambling for his clothes was exhilarating. He kicked him again as he chased him outside the house. "Fuck! Don't go!" Sarah screamed after them, but she was too late. He was having none of her bullshit anymore. It looked like Sarah was about to scream something at Mark when got back, but she decided against when she saw his eyes. She went completely quiet and it Mark noticed that she was completely nude and it looked like Sarah had just realized it too. She covered her breasts with her hands and she crossed her legs. Mark had never seen her so vulnerable, so unsure about herself. For the first time in a long time he felt like he was in power. This was just like when they had been kids and he had been able to force her to do what he wanted. "Fuck, Mark, get out and let me get dressed," Sarah screamed, but Mark ignored her screams and blocked the path to her clothes. He grabbed her wrists and pushed her back down on the sofa. He put his knees on separate sides of her body while his hands were holding the wrists above her head. Sarah's breasts were exposed and he could see that her nipples were still hard and she had a terrified look in her eyes. This was the first time Mark had seen a breasts this close in real life and he didn't care whether they were his sister's or not. He wanted to feel what they felt like if he touched them. "Mark, what are you going to do?" Sarah said and Mark could hear the fear in her voice and it felt good. He wanted revenge and this was a good start. "You must think I'm a fool, a complete pushover, Sarah!" Mark said, sounding much calmer than he felt. A part of him wanted to scream at her, but he doubted it would have the same effect as his calm voice. "I'm sorry, Mark, I didn't think about your feelings... Fuck, Mark, let me go you're really hurting me," Sarah said, close to tears, but it wasn't enough to convince Mark to loosen his grip. "I bought your lies, Sarah. I got you drugs and I lied to our parents, because of you and I got nothing out of it in return. I only got more pain, like my life wasn't miserable enough already, without having you humiliate me. How the fuck do you plan to make this up to me?" Mark said starting out calm, but by the end of it he was screaming at her at full strength. "I'm fucking sorry, Mark. I'm sorry you're a virgin, but don't take it out me. I can't help you with that. I just wanted some time for myself, for fuck's sake," Sarah screamed back at him. She had started to struggle to get away, but Mark was still holding her firmly in place. "I can't help you with that," kept repeating in Mark's head and his mind started to get filled with all sorts of wicked thoughts. "Why not? Why the fuck not!" Mark said in a loud voice as he shifted his body weight so she would be held in place by it and released her wrists and moved his hand towards her breasts. "What the fuck are doing? Fuck, I'm your sister!" Mark ignored his sister pleads and moved touched his sister's firm young breasts directly. The first he ever touched and he enjoyed it more than he thought he would. They were average sized and his hands were trembling as he gripped the soft flesh. He avoided looking Sarah in the eyes and his fingers started to play with her hard nipples. Sarah was just a girl in his eyes now. An eighteen year old girl with firm breasts who wanted him to play with them. It didn't take long until Mark felt a bulge pressing against his pants from the excitement. He was getting turned on by his sister's body. He enjoyed touching her breasts and he didn't care they were his sister's. Her blonde hair was spread out on the sofa behind her head and he could really see why everyone found her so sexy. He saw it too. He wanted her. "Stop it, Mark," Sarah begged him. "Don't do this. I'm your sister." "You guaranteed, didn't you, Sarah? I'm just holding you to your promise," Mark said and he realized that squeezing her breasts wasn't enough anymore. "Please," Sarah said and looked at him with her big blue eyes that were so difficult to say no to, but this time Mark had no such problems. It was wrong, but he wanted to punish her for all his failures, for all her lies. He wanted her to pay for what she promised. He didn't want to be a virgin and she turned him on. It was only logical that she paid him with her body. She was naked and it would be so easy. She had guaranteed that he would lose his virginity tonight. He wasn't able to convince himself, but the feeling of her stiff nipple with and the way his hard cock felt made him do it anyway. Mark didn't care if it was right or wrong; he wanted to have sex with her. He wanted to have sex with his sister. She owed it to him and he was going to make her pay up. "Don't do it," Sarah said as Mark removed his shirt. He grabbed her hand and moved it towards his bulge. "Don't." Sarah's word didn't stop him and he forced her hand to close the distance. Mark let out moan when he felt her fingers touch his hard cock through the fabric. It felt so different having someone else touch, even if it was through the fabric. It didn't matter that he forced her to do this. It still felt better than anything he had experienced and by now he knew that he wouldn't be able to stop himself. This was the only payment he was going to accept. "You guaranteed, Sarah," Mark said and moved her hand more forcefully. He enjoyed the pleasure of a girl touching his most intimate area, but it still wasn't enough. He wanted more. "Unzip me, Sarah," Mark said in a commanding voice he didn't know he possessed. "No, we can't, Mark," Sarah said before he slapped her and he could see that the way she looked at him changed. The anger still boiled inside Mark and he could see that she was scared of him. He felt her hand unzip him, his own sister was about to be the first girl to touch his erect cock directly. He looked her in the eyes to try to assess what she was up to. She seemed to have resigned to accept whatever he wanted her to do. A smile entered his face and he got up from her and removed his pants leaving him nude except for a pair of boxers. Mark didn't do anything to hide the erection from Sarah. If anything he was showcasing it to her. He wanted her to see how turned on he was. He was a real man with a real dick and he wanted her to see it. He could see the look of contempt in her eyes, but it didn't stop him. If anything her look spurred him on even more. Mark wanted her to see his cock. He knew it was sick, but he wanted Sarah to see how turned on he was. With one swift motion Mark removed his boxers and now completely nude just as his sister. Sarah sat in the corner of the sofa with her knees against her body in an effort to cover up. Her eyes were still on Mark and he did nothing to hide his erection. He stood there for a couple of seconds before he approached his sister. "I'm sorry, Mark," Sarah cried out as she felt Mark's hands spreading her legs apart. It had gone too far to stop. She had promised he would lose his virginity tonight and when he looked Sarah's neatly trimmed pussy all the guilt he felt got pushed to the deepest corner of his mind. She only had a small patch of hair above her pussy. Mark felt nervous as he let his finger trace up his sister's legs until it reached her pussy. To his surprise it was wet. He didn't know if it was because of him or the guy from earlier, but he knew it was a good thing. Mark wanted her to enjoy it when he penetrated her with his cock. He let his finger run up and down her slit until he found the entrance and pushed his finger inside her. He fingered his sister's wet pussy and it started to become even wetter. "You're wet, Sarah," Mark said in a calm tone, fascinated by how her pussy felt against his finger and the way her juices coated his finger. Her face was red with a combination of anger and embarrassment and she still had a look of disbelief. "It's not because of you," Sarah said before letting out a soft moan as his finger hit a soft spot inside her pussy. He had heard her moan from his touch and Mark got a huge grin on his face. He continued to work the same spot that made her moan earlier while his other hand pinched her hard nipples until he heard another moan. It was becoming clear that she enjoyed the feeling of his touch. "I heard that, Sarah," Mark said and grabbed her face, forcing her to look at him. "Fuck, Mark, stop, oh god," Sarah said before letting out another moan. Their faces were inches from each other now and he could see how she had troubles holding back her moans as he speeded up the movement of his hand. Mark's moved his thumb so it could touch her clit while two of his fingers kept moving in and out of her pussy. Her breathing got heavier and the moans came more frequently. "Are you going to come, sister?" Mark teased his sister, enjoying the power he had over her. He especially enjoyed the look of Sarah's face as she struggled to hold back her orgasm. It gave him a weird kind of pleasure knowing she was about to come with the help of his, her brother's hand. Mark had never seen anything sexier than the look of his sister's flushed face as she tried not to show him how good his fingers felt. She sweated; bit her lips and her eyes looked away from him. He could see how it got harder and harder for her not to moan. It felt like his fingers knew how her body worked, knowing which spot to touch. Her lips were slightly parted and her chest heaved up and down with each breath. Their eyes met again and he pressed his lips against hers and for the first time in his life he was kissing a girl. She couldn't resist him. His hand stimulated her soaked pussy. His thumb was firmly pressed against Sarah's clit, making circular motions while two of his fingers went in and out of her pussy. She felt too much pleasure and was too close to coming to resist him. Mark pushed his tongue inside his sister's mouth and sought out her tongue and entwined it with hers. His cock reacted to the pleasure and a shiver was running through his body as he enjoyed the first and best kiss of his life. He didn't know kissing could feel so good. He felt pleasure all the way from the toes and up. Mark broke the kiss just in time to see Sarah orgasm. "Oh fuck, I can't, fuck..." Sarah screamed out her pleasure. Mark felt her pussy convulsing on his fingers and a tremor ran through her body as the pleasure from her orgasm continued to spread throughout her body. His cock had started leaking precum earlier, but after seeing his sister's face experiencing an orgasm made things even worse. He was so horny and almost any touch would be enough to make him come. Sarah's eyes were closed and it felt like minutes until she opened them again. She had a look of satisfaction, but it quickly changed once she saw the smile on her brother's face. She looked away with a look of shame on her face. Mark wasn't done and he moved into position to fuck her. "Get a condom, Mark," Sarah pleaded, but Mark knew it was just a trick. If he left the room she would just run away and he knew she was on birth control. "I know you're on birth control, Sarah." "They're not 100% safe, Mark. I can't get pregnant," she said and looked up at him. Mark knew this was her last defense and his last chance to change his mind. His fingers had been good enough to make her come and he wanted to bring her the same pleasure again with his cock and he suspected that a part of her wanted it too. "I heard it feels better without one," Mark said and grabbed his cock and rubbed it against her pussy. Mark pushed the head of his cock against her clit before he moved it into position by letting it slide down her slit. He grabbed her head again. Mark wanted to see the look on her face when he penetrated her for the first time. He wanted her to look him in the eyes when he lost his virginity. She didn't look away. It felt like she had accepted that he was going to fuck and wanted to make it easier to bear by not struggling. Mark had never been so excited in his life. He slowly started to push his hips forward and the feeling of his sister's pussy wrap around his mushroom head was unlike anything he had ever experienced. His body filled with pleasure and it started to feel too good already. "It feels so good, Sarah," Mark moaned as he pushed even further inside his sister tight pussy. Mark could it in her eyes that she felt it too and soon wave after wave of pleasure swept through him. He pulled out a bit before thrusting deeper inside her again. Each thrust felt better than the last one and soon it was too much. He couldn't hold back anymore and his whole body started shaking and he started to ejaculate inside her. It all went so quick that he didn't even have the chance to pull out. The pleasure of his first fuck had overwhelmed him. "Oh god, Sarah," he screamed out as his orgasm filled him with pleasure. He felt his cock twitch as it unloaded his first load ever inside a woman's pussy. It was unlike anything he had felt before and it didn't matter that it had only been a couple of thrusts. A shiver of pleasure from the incredible feeling of shooting his cum inside his sister's pussy ran through him. It had all been worth it, the drugs, the failed date, it had all been worth it. The moment of pleasure was worth all the troubles. The moment he came inside her was the moment when everything felt right. He still enjoyed the afterglow when he heard Sarah's voice. "Are you done?" Sarah asked and Mark could hear some disappointment in her voice, but mostly relief. But Mark wasn't done and he already felt his cock starting to stiffen again. He pulled out and looked down at her dripping pussy. His cum was dripping from Sarah's pussy and the sight was making him hard again. He grabbed her face and forced another kiss on her. "Not even close," Mark said after he ended the kiss. He saw the look on her face when she felt his once more hard cock make it way back inside her. This time he was going to last longer. Mark couldn't get enough of her. It didn't matter that Sarah was his sister, only the way her body made him feel mattered. The mixture of her juices together with his cum made it very slick for his cock and he could thrust inside her with ease. His hand played with her breasts and he started to pick up the pace. It felt good, but this time the pleasure didn't overwhelm him the way it had the first time. Now he had time to enjoy how Sarah's wet pussy felt around his cock as to thrust inside her. Mark could see and feel that Sarah was starting to feel good. He saw it in the way she breathed and how her pussy tightened around his hard cock each time he thrust inside her. Her hips even started to move to meet his thrusts. He wasn't sure if it was to make him come quicker or if it she did because she wanted to reach her own orgasm. Either way it felt even better as she started to take a more active role and soon Mark was sucking on her nipples while their hips slammed into to each other. It wasn't just him who fucked her now; she fucked him just as much as he fucked her. Dealing with Sister She didn't hide her moans anymore and the way her pussy squeezed his cock made it very difficult for him to hold back. Mark could feel how his orgasm was approaching quickly and he started to thrust more rapidly inside her. He had a hard time keeping a steady rhythm as the tingling feeling in his cock became too much. His whole body screamed for release and he could see it in Sarah's eyes that she needed it too. "Don't come yet, just a little longer. Fuck. I need to come," Sarah said. She struggled with her speaking, overwhelmed by the pleasure of her brother's cock. Her moaning got louder with each thrust and soon it became impossible for Mark to hold back. He tried, but eventually it became too much. As soon as Mark knew he was about to come he grabbed Sarah's hips and thrust in and out of her as quickly as he could and right before he was about to come he felt how her pussy contracted on his cock and she let out a huge moan. Moments later it all became white, as the feeling of his sister's contracting pussy pushing him over the edge. Mark buried his cock as deep inside her as he could before the orgasm completely overwhelmed him. Mark held on to her hips with all his might as his cock pumped his seed inside his sister. It was unlike any other orgasm he ever had. The feeling was unmatched and hearing his sister scream as she came was part of the reason. He released more cum inside her as he continued to come. They had done something he would never forget. He still felt no regrets, even as he calmed down after the orgasm. It'd been more amazing than he ever thought it would be. He sought out his sister's lips once more and this time she kissed back. It was a short and sensual kiss, and he wasn't sure if it was a beginning or if it meant the end.
