A loud slam of the front door announced to Mark that his little sister had arrived home from her friend's house. She skipped into the sitting room where he was watching TV and promptly snatched the remote out of his hand. "Hey, what was that for? I was watching that!" Mark grumbled. Sophie stuck her tongue out at him. "You've been watching TV all day, it's my turn," she retorted. Mark grinned. He couldn't stay angry at his little sister and she knew it.
Mark and Sophie had a unique friendship. They had been home-schooled by their parents until high-school due to the remote region where they lived. The lack of other children around meant that the two spent most of their time together and had formed a very strong bond. Mark, at 17, was a year older than Sophie. He was 5' 5" and 11 stone. He disliked most sports but was naturally fit nonetheless. He had brown, shoulder-length hair and deep, brown eyes. Although he was the older of the two, he was definitely not the one in charge. Sophie liked to get her own way. Mark often joked that he spoiled her more than their parents and although it was a joke, there was a lot of truth to it, as he liked to make his sister happy. They had grown to become the best of friends.
Sophie was 16 years old. She was quite short at 5' 2" and had a quite toned body. She had disliked her looks as a young teenager and took up running to get into shape. At 15, she had started to blossom and at 16 she had become a very beautiful girl. Her hair was light brown and came down to the middle of her back and she had bright green eyes. It was because of Sophie that the family moved from their remote village to the suburbs of a large city. Her mother was struggling to keep up with homeschooling her and, after consultation with an educational specialist, they decided that Sophie was not being challenged enough with her education. So the decision was made to up roots and move closer to the city. Sophie was enrolled at a special school for talented children and mark was enrolled at a public high school. Sophie enjoyed the school and made friends, but as she was no longer the smartest, she disliked having the attention off of her. It was because of this that she liked to constantly have Marks attention on her.
Sophie threw a cushion at Mark. "Move over, you big lump!" she teased, and scooted over beside him. It had become a habit for them to cuddle up on the couch after school until their parents got home. Mark threw the cushion back at her playfully. "How was your day today?" he enquired. "Oh it was okay I guess." Sophie muttered. " Caroline kept going on about her holiday to France." Mark gave his sister a hug. He could tell that she had had a bad day. "How about some hot chocolate?" he asked. Sophie's face lit up. "Ooh yes please!" she squealed with delight. As Mark made the hot chocolate in the kitchen, Sophie called into him from the other room. "What are you getting up to tonight?" she asked hopefully. "Maria is coming around." Mark called back to her. Sophie's face fell. She didn't like Maria at all. Mark and her had started going out three months ago and she came to the house every other Saturday. Their parents loved Maria and complimented on how polite she was, but she treated Sophie like a little girl, teasing her and demeaning her. Nobody else seemed to notice though and when she hinted at it to Mark, he teased her about being jealous of not getting his attention. Mark walked in, carrying the mug carefully. "Careful, don't burn yourself." he said. Sophie forced a smile. "Of course I will be." she replied.
That night, Sophie sat in her bedroom reading. Mark's bedroom was next to hers and she could hear him and Maria giggling in there. The last time Maria had been around, Sophie had gone in to borrow a book off Mark, and had walked in on Maria under the covers and Mark looking disheveled. She pretended not to notice anything and Mark didn't say anything when Maria left, but that night Sophie felt very uneasy thinking about her brother with a girl. It didn't seem right to her. She eventually dozed off with the book in her hand but was awoken by raised voices in the next room. Mark and Maria seemed to be having a fight. Sophie put her ear to the wall and could just make out Mark say"... why don't you just leave?" before Maria stormed out of the bedroom. She shot Sophie a glare as she passed the open door, and slammed the front door to the house indignantly.
Sophie tiptoed into Marks room. He was sitting on his bed looking both furious and shaken. "What happened?" whispered Sophie. "Nothing... " responded Mark. "Tell me." urged Sophie and mark hesitantly obliged. "She... she said you were a spoiled brat. I was just so angry. I don't want anything to do with her. I'm sorry I didn't believe you that time you told me... " croaked Mark. Sophie wrapped her arms around his neck and pulled him close. "It's okay, Mark." she whispered, looking into his eyes. As she gazed into his deep, brown eyes, shimmering with tears, her heart melted and she wanted nothing but to make him happy. She inched her head forward, her lips moistening. She felt her eyes close of their own accord as she tenderly placed her lips against his. She kept them there for what felt like an eternity. She felt tears build up in her eyes as a wave of emotion flooded over her. She pressed harder against his lips as Mark moved his hand to the back of her head. She parted her lips and slid her tongue into Mark's warm mouth, barely brushing against his moist tongue. The kisses started to build in passion as moved her hands underneath Mark's t-shirt. As he felt Sophie's hands on his skin though, Mark seemed to wake from a dream. He pushed Sophie off and turned away, shocked at what had happened. Sophie tried to soothe him but Mark, filled with guilt over what he had just done, pushed her away and asked her to leave him alone. Tears streamed down Sophie's face as she ran back to her own room and locked the door.
Mark wasn't waiting on the couch when Sophie arrived home the next day, or any other day that week. He spent the whole time before their parents returned home in his bedroom, and the whole time after that in their company. Sophie couldn't find a single minute to talk to him alone. Her heart ached as she longed to kiss him, to press her body against his and make love to him. She wanted to give herself to him completely, but he had rejected her, and her heart broke for it.
The next weekend, their parents had to leave for a conference in a different state. The two would be at home alone but would not be allowed out of the house other than to get food. Sophie was eager with anticipation as she saw this weekend as her chance to talk to Mark. When her parents finally left she went up to Marks room, but the door was already locked. She called through the door to him but there was no reply. She sat outside the door and continued to call until eventually, the door was unlocked and Mark came out. Sophie moved to hug him but Mark stepped back. "What's wrong?" cried Sophie. "Why don't you want me? You're the only person I care about. You're always there for me. I want to be with you. I love you, Mark. I love you." "I love you too, Sophie." whispered Mark. "Then why don't you want to be with me?" she choked, tears streaming down her face. "I do." Mark said, even quieter. "Then kiss me." Sophie's voice quivered as she said it. She prayed that he wouldn't walk away. She couldn't face not having him kiss her again. She closed her eyes and felt a hand, wiping the tears from her face. She lifted her head to see Mark leaning towards her. He put his arm around her and softly pressed his lips to hers. Fireworks exploded in Sophie's stomach as their tongues found their way into each others mouths.
Their passion increased rapidly and they stumbled backward into Mark's bedroom. As they tumbled onto the bed, Mark's hands moved to the buttons on Sophie's blouse. One by one he undid them and pulled the garment off before unclasping her bra. As it fell to the floor he took Sophie's breast in his mouth. She gasped and threw her head back as pleasure rushed through her. She ran her hands through Mark's hair and pulled him closer. After several minutes of intense pleasure, Sophie pushed him off and pulled his shirt off before unbuttoning his pants. She pulled them down quickly and removed his boxers, releasing his hard cock. She wrapped her hand softly around Mark's warm rod and slowly stroked up and down. Mark moaned with pleasure and a bead of precum glistened on the head of his member. Sophie stuck out her tongue and touched it to the sparkling precum. After examining the taste she slowly wrapped her lips around the head of the throbbing cock.
Mark was in heaven as his sister slowly lowered her head, taking the warm rod deeper into her mouth. Suddenly she gagged as it hit the back of her throat and she blushed innocently. Mark sat up and lay her down. He lifted up her skirt and removed her soaking panties. He kissed his way gently up her legs and Sophie squealed with delight. He gently touched his tongue to the moist slit and Sophie's body tensed with pleasure. He ran his tongue up and down, pushing it in further each time. Sophie was going wild with ecstasy. All of a sudden she let out a high squeal of pure bliss as Mark pushed his finger inside her. Her hands gripped the sheets and her back arched as her entire body tensed up. "Mark!!" she screamed. "Oh Mark!!" Her body relaxed and she sat up. "I want you inside me Mark" she whispered. She pushed him slowly onto his back and kneeled above him. "Are you ready?" she asked and Mark could only nod his head. She slowly lowered herself. She felt the tip of Mark's cock touch her dripping wet slit and lowered herself further. The head parted her and slowly pushed inside. The feeling was indescribable as Mark's cock filled her tight, wet pussy.
Suddenly she met resistance. She gripped Mark's hand tightly and dropped herself quickly onto him. She let a gasp of pain, but the pain quickly ebbed away as a wave of pleasure washed over her. Mark moaned as his sister's tight virgin pussy gripped his hard cock. Sophie started moving up and down, sliding it in and out. She could feel her pleasure building in intensity until she felt she couldn't take it any more. All of a sudden she felt an enormous wave of ecstasy wash of over her. Mark couldn't take it any more and started to cum, squirting deep inside his sisters womb. The feeling was too much for Sophie and tears began to run down her face as her entire body was engulfed in bliss. She collapsed on top of Mark and wrapped her arms around him, holding him tight. "I love you, Mark." she whispered. "I love you too."whispered Mark, and they drifted off to sleep in each others arms.
