Jacob could not be prouder of the woman his little sister Cassie had become. She had just turned 18 years old yesterday and was a stunning, beautiful, intelligent woman. Her sharp green eyes were complemented by her sweet smile and often blushing cheeks, her golden hair waving gently every time she laughed. Her slender body had recently started to really develop curves, as her breasts had filled out enough to really fill her entire hand and a bit more. She was in incredible shape being on the volleyball team in high school varsity, her strong, tight but thick thighs crowned by her muscular, curved ass. It was a body women would kill for and men would die for.
Jacob didn't think about any of this of course. He loved his baby sister for the kind and caring soul she had turned into. She was incredibly popular in school because she never let the fact that she was on track to be valedictorian, was perhaps the most beautiful girl in school, or the fact that she was an athlete - affect how she treated others. She was always giving and kind - the first to volunteer for charity projects and the first to give away her own things when others needed them.
When their parents had died in a car accident only a month after she was born, Jacob had been 18. Rather than allow Cassie to be given up to the foster system, to their grandparents who were getting too old to raise a child, or for adoption - Jacob committed to raising Cassie himself. He got a job as a desk security guard so he could pay for college while studying, and was able to get through school without spending much time on campus. He gave all the rest of his time into raising Cassie. They had lived in a studio apartment while he went to medical school. He had done everything possible to ensure she never had to go hungry or lack in anything.
He had done everything the way he remembered his parents raising him and tried to follow them the best they could - from discipline to love to education. Their bond was incredibly close, Cassie knowing the sacrifices her brother had made to raise her and Jacob ever proud of the young woman Cassie had become. Their parents would be incredibly happy.
Jacob considered that worth everything. Every bottle of formula, every hour participating in the PTA while holding a pathology book, every moment he watched her play soccer while studying for his board exams. Every moment had helped shape her into who she had become. Even greater sacrifices had been made - Jacob's ex-fiancee Amy had told him eight years ago the he'd have to choose between raising Cassie and getting married, but that she wasn't ready to be a mother to her own sister-in-law. Jacob chose raising Cassie, heartbroken.
"Cas! It's time to wake up!" Jacob yelled from the kitchen for the third time.
"Jacob I can't!" Cassie mumbled back, loudly.
"I'm making pancakes and I have to be on time at work today! I can't drop you to school if you're late, you'll need to take an Uber, now let's go!" Jacob yelled.
Jacob was a single physician with no children, just one little sister to take care of but had gone ahead and bought a 4,600 square foot house in the middle of the one of the nicest suburbs of the city so he could be close to the hospital where he worked. The house was massive and empty, too empty for them. He tried his best to stay out of it as much as possible and to remain active. He had bought it when he and Amy were engaged and had planned to fill it with their new family. Those dreams had died eight years ago.
"I'm coming, I'm coming" she yelled back as he heard her bathroom door shut.
"Finally, Jesus, that took forever" he mumbled as he scraped off the pancakes onto the plate. They never celebrated Cassie's birthdays with a single day - it was always birthday week. Chocolate chip pancakes with maple syrup were her favorite so he had made them for her. Tonight would be her party with their friends and family at the Four Seasons. Jacob had decided to really treat her and her friends today. She had been so patient growing up with his limited ability to provide as a student, he really wanted to let her have a little fun.
He went downstairs to the basement and into the workout room and began his routine. Today was chest and triceps. A few minutes later, Cassie come downstairs, her hair wet and wrapped in a towel and saw her brother from the side benching. She didn't know how many pounds he had on the bar but she knew it was a massive amount she wouldn't even be able to move. She heard him exhale as he pushed up and watched the machinery that was his toned, muscular body, individual muscles in his arms clearly visible and working as he lifted the massive weights.
Her gaze lingered on his arms and made its way down to his thick chest, itself a perfectly toned masterpiece. If anyone needed a male supermodel for chests or arms, it would be him she thought to herself. His arms gleamed with his sweat. She suddenly shook herself out of her thoughts about his muscles, and decided to make herself known. She waited till he had placed the weights down. "Ahem" she said.
"Oh, hi Cassie" Jacob said. "Did you see what's for breakfast!?"
"Yes, pancakes!" Cassie squealed. Thank you Jacob. "Are going to eat with me?"
"Yeah, I'm coming up Cas" he said, sitting up. He wasn't wearing a shirt at all for his workout, and Cassie noticed how much bigger his muscles seemed after he had worked out. His abs were clearly visible. All of Cassie's friends would make lewd comments about Jacob, and she had started recently to understand why.
Jacob was the whole package - he had money, he was successful, he was in shape, and to his benefit his personality was more than just his job. He loved having fun, traveling, and enjoyed the simple things in life. The house was filled with pictures of Jacob and Cassie visiting Thailand, eating lamb chops in Morocco, and skiing. In the absence of their parents, Jacob had made sure to give her a complete and fulfilling childhood. He took incredible care of himself and looked younger than his 36 years.
Cassie sighed as she made her way upstairs, her yoga pants hugging her perfectly shaped ass. Jacob followed her, not looking at anything, focused on his phone and reviewing patient notes.
"So, excited about tonight?" Jacob asked.
"Yeah, super excited. Thank you so much Jacob. You didn't have to do all this!" Cassie said.
"Nonsense. This is your 18th birthday. I want you to have fun." he said.
"You're awesome, even if you don't let me do all the stuff I want to do" Cassie said.
"I am pretty damn awesome" Jacob said. "If I let you do anything you wanted I'd be a pretty shitty big brother and an even worse legal guardian."
"I guess that's true." Cassie said.
"Are we watching Office re-runs tomorrow night as usual?" she asked.
"That's the plan! I think we're at the one where Jim is gonna tell Pam." Jacob said.
"Oh my God, that's my favorite!" Cassie replied, while stuffing her mouth with pancakes.
"I think I knew that" Jacob replied, eating a pancake himself while checking his medical notes.
"You know, Jacob, now that I'm 18, can I go out with my friends without a curfew, by myself? I mean I'm an adult now." Cassie said.
"You're an adult, but you live in my house, which means I will still be up late waiting for you if you're out. I trust you Cassie but I can't help the fact that when you're not here, I don't sleep. So, you need to be home by midnight. And no being alone with any boys." Jacob replied.
"That's such bullshit. None of my friends have any of these rules Jacob. Their parents let them do whatever they want. They got phones before me. They got later curfews than me. They also all are no longer..." she stopped herself.
"No longer what?" Jacob asked.
"They also have been with guys..." Cassie said.
"What does that have to do with you?" Jacob asked.
"I've never experienced any of these things!" Cassie said.
"Mom and Dad would have never let you go out late with any guy" Jacob told her.
"WELL MOM AND DAD AREN'T FUCKING HERE. I NEVER KNEW THEM!" she yelled at her brother.
Jacob didn't lose his composure. If he lost his composure he would escalate the situation. Instead, he softened his voice. This was his baby sister, in a literal sense. He had literally raised her. He knew her. He knew what she was feeling. His rules were harsh but he was doing this alone.
"I know they aren't here Cassie." he said, matter-of-factually, with a softness in his voice. "And I'm sorry you never knew them. All I have to say is I've never, ever seen them as happy as when they brought you home. And all of the love that they would have given you, I've tried to give you. And every way that they would have protected you I've tried to protect you. And everything they taught me, I've tried to teach you."
"Fucking hell" Cassie said, sitting down. She was no longer yelling at her brother. She was just crying. Crying at how shitty it was to not have them. And to not even know how to miss them because she never knew them to begin with.
"I'm not Dad Cassie, and I'm not your dad. And I'm not Mom. But I'm just trying my best here. I tried my best. I tried to give you every experience of a full childhood from gymnastics to soccer to basketball to ballet. From trips overseas to competitions. I tried." Jacob said, sincerely. "You've seen 6 out of 7 continents. You can't say you didn't get to have an experienced life. I tried my best.."
"I know you did, Jacob. You did more than you were supposed to." Cassie said, in between tears and hiccups from crying.
Jacob continued. "And I'm doing this alone so maybe my rules were too harsh. I did keep you away from boys. I did keep you from getting a phone. I did have harsh curfews. I did scare away every guy you met. That's true. But you're not going to be here for much longer. I'm asking that you respect the rules of the house while you live here. You're off to college in a few months and you can live the life you want. I'll still support you, but I just can't deal with you doing all of that stuff while you're living here."
"I understand" Cassie said. "I'm sorry. I do love you a lot. And you never have to tell me that you're not Dad. I'm sorry you felt you had to say that. You did more for me than I've ever seen any father do for their daughters. If they were half the man you are they'd be the best fathers in the world. I'm being a brat and I'm sorry."
"I'm sorry too. And I love you too Cas." Jacob said.
They sat in silence, Cas looking at her brother's face. Kind, chiseled. Strong. But loving.
"Alright, I gotta get going, I have to do rounds and review my students' notes. Let's go" Jacob said breaking the silence.
They put their shoes on and ran out of the house.
As Jacob drove away after dropping her off, he could fear his tears start to come into his eyes. She was a lovely young woman and was going to be just fine. He could trust her. He knew it. She was on her way to a beautiful future. But the sacrifice had been so, so much. He was 36 now. He had given up marriage, and family, and so many experiences so he could raise her. When he was younger he had always thought he'd have kids by now. A wife and children. He was a 36-year old physician whose friends, old girlfriends and ex-fiancee were all married and living full, active lives as father and mothers with families of their own. He had his job and an empty house. Almost every woman had turned down being with him when they found out he came with a full-time ward that happened to be his sister.
The emptiness would kill him. The loneliness. Not having her laughter and her yelling and her joking in the house. He shuddered thinking of what it would be like to be alone, and thought of the night the police had come to his door holding Cassie in a blanket. She had been crying at the top of her lungs as the officer informed him that their parents were dead because a drunk semi-truck driver had slammed into them at highway speeds. Cassie had been at the daycare and they had never picked her up.
The loneliness he had felt at that moment was something he never wished on his worst enemy. And he felt like the moment she left, he'd face that loneliness again. He put his feeling aside as he pulled into the hospital parking lot and went into work. Solving daily medical problems would be his salve for now. He steeled himself as he went inside and focused himself on work.
------------------------------------------
The party was wonderful. Jacob and Cassie's cousins, a number of Cassie's friends, and her volleyball team had all come to the Four Seasons. They had a blast and ate like royalty.
As they drove home, Cassie turned to Jacob and touched his hand.
"I don't think there's a brother better than you on the entire planet." she said.
"That's so sweet Cassie. I'm just glad you had a nice birthday." he responded.
"I mean it. I don't know what I did to deserve you. You gave up...so much" she said and her own sobbing stopped her.
"Its OK Cas. You don't need to be crying on your birthday. Let's just go home." as they pulled in.
Jacob went to bed, in his boxers as usual, in the massive master bedroom.
Around 11 p.m. he heard a knock on his door. He always left his door open so he could hear if Cassie ever needed anything.
"Yeah Cas?" he said.
"Can I sleep in your room? I just don't want to be alone. You won't let me go out late so at least let me stay here with you." Cassie said.
"Yeah, of course." he told her.
Cassie went to Jacob's king-size bed, as he lay in the middle, and snuggled up to her brother's back. She was wearing a silky robe and nothing underneath it except her cotton panties. She realized as she touched his back, that he was shirtless. She could almost feel the muscles in his back as he lay there, the ones he worked so hard on perfecting every day.
"You smell nice." Cassie said
"It's just D&G cologne I think" Jacob responded.
"Whatever it is, it's nice" she said.
"Well glad you're happy. Let's go to sleep Cas." Jacob said. It had been a long day.
"Ok" she said.
Soon, his breathing was deep and regular. She lay there looking at his back and shoulders. He was a massive man, and she felt like he was a lion sleeping in the bed. She compared him to her own size. He was six-foot three, more than 200 pounds, almost entirely muscle. She was five-foot six, and had recently been incredibly slender until volleyball started causing her to put on a little more muscle on her thighs and ass turning her into the shapely beauty that guys couldn't stop looking at. She was tiny in comparison to him but everyone knew that were related just by looking at them. Their skin tones were exactly the same, and their green eyes were their mother's.
She needed more than a snuggle - she needed something to hold on to. She moved herself to spoon him, keeping her robe as a barrier, and wrapped as much as she could of her arm around his waist until it found a natural position. She felt warm and protected, and finally fell asleep, ignoring the fact that her panties had started to slowly get wet as she held her brother.
She woke up in the morning and she noticed that he was no longer facing away from her. She cuddled into his shoulder and one of her thighs was on top of his. Her robe had fallen away from her chest exposing one of her pink nipples just slightly. He was still sleeping, but his arms surrounded her, locking her into his embrace. It felt absolutely wonderful to be wrapped up like this. She felt warm and safe and loved. But - her panties felt cold...had she peed her pants in the night? She slowly reached down and realized that she had basically been dripping all night. As her hand came back up she brushed up against something that felt like a solid pole in front of her pelvis and realized exactly what it was. She began to freak out.
She took a deep breathe to calm herself and accepted that she had just brushed against Jacob's penis. The room was filled with Saturday morning light and it was impossible for her to not be curious. She slowly lifted the blanket and saw his cut six-pack abs leading down to his muscular pelvis and then his white boxers. And they were sticking out from his pelvis what seemed like eight inches.
"Holy shit" she whispered to herself. She had seen a little porn before even though she had never been with a guy, but her brother was packing a baseball bat under there. The white boxers did not hide much so they were a little transparent and she could make out the contours of Jacob's penis. It was clearly incredibly thick, maybe the size of her wrist? Either way this was too much. She covered him and herself back with the blanket, covered her exposed nipple with her robe and tightened the robe.
"Jacob. Jacob?" she said whispering.
"Hmm. Cassie, baby" he said in his sleep, whispering.
"Jacob" she said again, and his eyes suddenly opened.
He looked at her eyes and said "Caaas" in a dreamy voice, and smiled the most beautiful smile she had ever seen in her entire life. His entire face lit up as he looked at her, with a sleepy, satisfied, happy gaze. She was so thrown off at the way he looked at her - she had never seen him smile with that much happiness in her entire life.
Suddenly, he looked around and the smile disappeared immediately. Within a moment.
"What the fuck was that about" she thought to herself.
"Hey" he said as he pulled away from her and retreated into his side of the blanket. "Did you sleep OK?" he asked, his parental-slash-big-brother voice on, every tinge of his sleepy, relaxed, happy voice gone.
"Yeah, I slept great. It was just my birthday and I didn't want to be alone for some reason." she explained.
"Yeah, no, I get it Cassie" he told her as he got off the bed and stepped into the bathroom.
"You have to make the bed if you're going to lay there." he told her.
"OK, no problem" she said, as she heard the shower turn on.
She realized that she had not only wet her panties, but had wet his sheets as well. How much had she dripped last night? She got up as she got ready to change the sheets. As she rose to get up, she decided she'd prefer to stay in the warm sheets, and let what she had dripped from her stay on her brother's sheets, almost feeling like they belonged there. She wanted to stay snuggled in the blanket and wait till Jacob came out.
She rolled over towards his side of the bed where his warmth still held and put her head in his pillow. It smelled like him. A scent she was deeply familiar with, but for some reason, today, it did something to her it had never done before. She could feel goosebumps on her arms, and a gentle tickle between her legs. She ignored it for now and lay here in the bed, Jacob's warmth still on the blanket and pillow, feeling less lonely than she ever had in her life.
A few minutes later, the shower turned off and the bathroom door opened, and Jacob was greeted with Cassie's smiling face in his bed, as he emerged wearing nothing but a towel around his waist. His dripping wet body, light black hair on his chest down to his stomach accenting his chiseled frame and muscular build. His green eyes looked at his sister, a little shyness in his gaze from the nearly inappropriate situation they were in. She could make out the outline of what was clearly his thick cock underneath the towel.
"Cassie, I need to change." he told her sternly.
"But your bed is so warm!" Cassie said, smiling.
"Cas, I'm not wearing clothes, I need you go to leave please." he told her again.
"OK, OK, I'm out" she said, and jumped out of the bed, wrapping herself up with her robe. She left the room and closed the door behind her.
"Fuck, how are you so perfect." she heard him say quietly behind the door.The rest of the Saturday passed without much incident.
Cassie had to do homework most of the day and borrowed Jacob's car after to visit her friends. He spent some time working out and they met up that night and cuddled on the couch with a blanket to watch the Office.
Cassie had started becoming a great cook and had made lasagna for them. After eating and watching a few episodes of their show, they made their way to their bedrooms. A few minutes after Jacob was in bed, Cassie popped into his room and poked her head through the door.
"Can I sleep here again tonight?" Cassie asked.
"This is becoming a habit isn't it?" Jacob responded.
"Not a habit, I just hate sleeping in my room alone the past few days for some reason. I just want to be with you even if you make me sleep on the floor." Cassie said.
"Of course you don't have to sleep on the floor" Jacob told her. "Come here and get comfortable. Do you want your own blanket?" he asked.
"No, I prefer yours, it's very nice." she said
"It is nice and very expensive." he told her.
She wasn't wearing a robe this time, just her panties and a tank top that was long enough to just cover her panties, her breasts squeezing out of her tank top and his nipples clearly visible underneath. He looked her up and down and quickly looked away.
"C'mon, get in." he said.
She climbed into the bed with him and lay on her back, her shoulder touching his back as he lay, turned away from her.
"Why do you always turn away when I'm in here?" she asked him.
"I like sleeping on my left hand side" he said.
"That's not true. I've woken you up many times and you've been on your right." she responded.
"Cassie I don't know, I just sleep this way when you're here. It's more comfortable." he said.
"What if I want to talk?" Cassie asked.
"You can hear me and I can hear you, what's the big deal?" he said.
"Ugh" she said, staring at the ceiling.
He shook his head and turned his entire body toward her in bed, laying on his right hand side with an annoyed but smiling expression on his face and looked at her. Looked into her sweet green eyes that he had known forever. Her golden hair on either side of her face.
"What do you want to talk about." Jacob asked.
"I want to get to you know you better." Cassie said as she moved closer into his massive frame with her petite body, her hands making their way towards his hips. She could already tell his erection was at full-mast. Had she done that to him? There's no way she could know for sure.
"What does that mean Cassie?" he said, half-aware of what the look in her eyes meant. And knowing that everything about it was inappropriate, wrong, and against every protective fiber in his being.
She didn't want to play this game anymore.
"I want to know how to make you happy." she said, and moved her hand directly to the base of his cock, still outside his boxers. She reached down while looking into his eyes.
"Cassie what the fuck are you doing?" he said, springing back. She did not let that deter her, she followed him until her hand was back in place on the base on his cock, outside his boxers.
"You're huge Jacob." she said.
"Cassie what are you doing?" he asked her.
"I'm learning about you." she said "You haven't been with a girl in months. Years?" she asked.
There was no denying that the touch of her hand was electrifying to him. Electrifying, and wrong, and horrible and the most wonderful thing he had ever experienced. Whatever was happening here, he could not abide.
"Cassie, you can't do this. We can't do whatever it is that you want to do. I'm like your father Cas." he told her.
"You just told me this morning you're not my father. And you're right. You aren't. And you never will be." she said, smiling.
"Well I'm your older brother. I raised you." he said, as her hand slowly made it's way into his boxers, and she could feel the skin of his little sister's hand against his pelvis. She was gently gripping his base and just slowly moving it back and forth, not even a complete stroke.
He grabbed her hand, still gentle with it, and pulled it out of his boxers and placed it on the bed. He rose off the bed and got up, standing there, his massive erection sticking straight out inside his boxers.
"You need to leave my room Cas." he said.
"I'm sorry Jacob. I didn't mean to..." Cassie started out.
"Cas. Leave. Sleep in your room." he said, staring at the floor.
The tears began to fill her eyes. "I'm such an idiot" she thought to herself, as she got up, and quickly left the room, closing it behind her.
------------------
Sunday morning came and consisted of Jacob keeping a steeled, almost emotionless expression on his face the entire day while doing all the same things they usually did. He made Cassie breakfast, did the laundry, went over some medical dictation notes, and worked out before mowing the lawn.
Cassie couldn't look him in the eye, and he couldn't look at her either. The silence was so loud in the house that it felt like it was a tangible fog hanging over the house. Cassie went out to dinner with some friends and Jacob spent the evening with a few buddies from his residency days. They ended up coming home around the same time, 9:30pm.
"Hey Cas" he said to her as he walked into the house and saw her taking off her own shoes.
"Hi Jacob." she responded.
"I can't handle the silence. Can I talk to you?" Cassie asked.
"Yeah. Meet me downstairs in the dining room in 10 minutes." he said.
She hated that it was the dining room. That's where they would have serious talks. Where they could sit at a table, not a couch, and often where he would discipline her or tell her what she did wrong. She already decided that wasn't happening. Five minutes in, she went to her room, stripped off her clothes, covered it with a robe, and walked into her brother's bedroom where he was changing into boxers and a t-shirt.
"I said meet me downstairs Cassie" he said, to turn around and find his baby sister with her robe wide open, and her naked body clearly visible underneath it. She dropped her robe and stood before him utterly naked.
"Cassie Jennifer Micheals, what the fuck are you doing?" he said, shocked as he looked upon his sister's naked breasts, nude stomach and taut bare thighs for the first time. And of course, her clearly visible pubic area, completely shaved.
"I'm not leaving this room until we talk, and if you want to kick me out you're going to have to put your hands on me, and as you can see I'm not wearing a goddamn thing. Get on the bed so I can say what I need to say."
Jacob realized his sister had her stubborn girl voice fully on. She really would make him handle her naked body to push her out if he didn't comply. He sat on the bed.
"You spent your entire youth taking care of me." Cassie said, tears in her eyes.
"I did, because I love you and because it was my job. I don't know what the fuck you think you are doing." Jacob responded.
"Yeah, but you lost entire chances at having a normal family when you wanted to start one." she said.
"I'm only thirty-six Cas, I can still have a family." he responded.
"Yeah, but there's no woman on Earth who'll give you what I will." Cas said.
"What's that?" Jacob said.
"Everything" Cassie replied. My entire body was raised on your money, your work, your love. You have the greatest right to my pussy. To my body. To my womb. To my love. No other woman will give herself to you the way I will. Everything Jacob. All of me."
"Cassie, what the fuck." Jacob said.
Her fair skin seemed to glisten, her brownish-pink nipples prominent in the center of her thick but modestly-sized breasts. Her waist perfectly curved before it made its way to her muscular volleyball thighs, her public hair perfectly shaven. She was the most beautiful thing he had ever seen in his life, young, tight, untouched, and with the sweet smile he had known forever.
"I want to be yours Jacob. I want to be your girl, your woman, your sister, your wife. The mother of your children. I want to give all of myself to you. Where else will you find an 18 year old woman who wants to be your little pleasure slut for the rest of her life? Who dreams every day of having your babies again and again and again. You want a family? You want a wife? You want all of that? Have it with me. With your Cassie. I'll be your Cassie forever."
She approached him as she sat on the bed, shocked.
"Cassie, I can't do this with you." Jacob said.
"Your cock is harder than ever before because you want to do this with me. I'm a virgin Jacob. You kept me a virgin. Neither of us knew at the time it would be for you. You worked so hard. You sacrificed so much. Let me be your prize. Let me be your wife." Cassie said, as she moved between his legs.
"I did all of that out of love for you, and out of love for Mom and Dad. I didn't do it so I could have you for myself. I did it so that you could grow up and be a happy, healthy human being." he told her.
But he could not deny his cock was dripping with pre-cum, and no matter what he did, he could take not his eyes off of his little sisters curvy, sweet little body, her newly mature breasts with her nipples sticking out, begging him to kiss them.
Cassie replied, "I am a happy, healthy human being, and I want to give myself to you. I want you to take my virginity. I want you to make me your woman Jacob. Unless...that's not what you want. Unless I'm not the type of woman that you'd want to be with."
"Fuck no, that's not what I'm saying. There isn't a woman on earth more perfect than you Cassie." he said. "But I'm your brother, and I'm just so much older. And I'm your brother, holy shit. This isn't even possible!"
This was normally the most stoic, in-control man she knew, but to hear him and see him look a little weak, almost as if SHE was the crack in his armor, made her a little happy inside.
"I know I'm young" she said. "But I'll keep you young too. I'll be your tight little vixen. It's every man's dream isn't it. To have a tight young little virgin woman that's all his. No matter what age men get they love the idea of young women. Let me be yours." she said as she slipped between his legs and knelt, no more than half a foot separating his rock-hard penis from her dripping pussy. He could smell her sweet scent now and it wasn't the scent of a little girl. It was the pungent, strong smell of a young woman's pussy.
"I'm not going to fuck you and ruin this relationship Cassie. You're my baby sister. You're my little girl, whether I'm your dad or not." Jacob said.
"I'm not asking you to fuck me and ruin our relationship Jacob". she said. "I'm not just asking for sex. I'm asking you to let me be the woman who soothes your pains, orders Christmas pajamas for you, has your babies, makes your kids breakfast. I want to take our kids to school. I want to raise them with you. I want to teach them the way you taught me and Mom and Dad taught you." she said, pouring her heart out.
"Cas, listen." Jacob said.
"I want to finish." Cassie responded. "I want to fill this house with pictures of us and our children and our memories. I want to go on vacations with our family. I want to rub your feet when you've had a long day at work. I want you to watch my ass in tight yoga pants in the morning while I pack lunches for our children. I want to make you your favorite food. I want you take care of me and love me and satisfy me and let me satisfy you, for the rest of our lives. I want you to give me back rubs the way you always did but not as a big brother, but as my lover. I want to scream your name in pleasure every day. I hear you in the shower jacking off you know. You haven't had a woman in your life for so long. But I'm here - you never have to jack off again. My body will be here to absorb your every lust, every drop of your cum. I'm ready to give all of myself to you. Do you understand?" Cassie asked, as she rest her hands on Jacob's thighs.
"Cassie, how do you know? How do you know you want to do all this with me. I'm 18 years older than you honey. I'm your older brother. You haven't even known any other guys. You haven't even had a boyfriend because I didn't let you. You want to break the biggest taboo known to man and dedicate yourself to me? I'm not perfect, and I'm related to you, and I'm older. I'm going to get older." he said.
All the while, he could stop looking at her beautiful, bold face and looking up and down her naked body. No matter what they decided, the look of desire in his face would never be forgotten by Cassie, nor would the fact that he had seen her secrets and she had seen his.
"I love you Jacob. Not just as a brother or an adopted father. As a man. You're kind. You're strong. You're gentle. You're funny. You're just everything I want in a man. No other man will be able to compare to you no matter how much I look. I've seen you in every situation a woman can see a man. I've seen how you treat people. You literally made me what I am. How many people on the planet could see everything a person sees when they are raised by them, and find them to be as perfect as I find you? I don't need to have any other experiences to know I've found the man for me. I know I'm young but you know me. I will learn everything. I will kick ass at being your wife." Cassie said. She rubbed her hands gently on her brother's muscular thighs.
"Cas" he said, as he placed his hands on top of hers.
"I'm worried I did something wrong. That I did something that caused this." he said.
"You think you messed me up somehow? No. You didn't. Life messed things up when it took away Mom and Dad. But life made it better when it gave me you. I'm yours Jacob. Look at me. Look at me and tell me you don't want to fuck me. That you can't imagine what it would feel like pumping your cum into my tight virgin pussy. That you don't want to imagine me pregnant with your baby. That you don't enjoy the idea of my ass in yoga pants in the kitchen making our kids lunches before school. That you don't enjoy the idea of coming home from the clinic and fucking me in the shower. That don't enjoy the idea of rubbing my back after a long day before fucking my ass. Of attending our kids' graduations together. That's the life you can have. Just take it. It's yours."
"Cas, this can't be taken back. And what would Mom and Dad think?" Jacob said, as she got closer to him so that the head of his cock was touching her thighs and her face was inches from his own, her hands resting on his massive shoulders.
"Mom and Dad believed every sin of every human being was already paid for. If that's the case, nothing we can do is going to take us away from them or wherever they are. You think they care where they are now as long as both of us are healthy, and happy, and love each other? I don't think so."
"Cas" he said, as she leaned in, and kissed him.
His every effort to resist her irresistible body only increased her in desire for him, and respect for him. Nothing about him existed to take advantage of her. It was pure love. Pure, unadulterated, selfless love. It's precisely why she wished to give herself to him. Had he been trying to push himself on her this entire time, she might have been creeped out. But he resisted. He suppressed his desires out of love and his protective nature. That kind of selflessness deserved a reward. It was going to be her entire being.
She explored the inside of Jacob's mouth as he felt the electricity of his baby sister's tongue. She tasted sweet. It wasn't from food or toothpaste - it was her. Her saliva tasted sweet to him. Almost like it belonged in his mouth. He sucked on her tongue as he brought his hands to her waist and she moaned into his mouth. They slowly separated.
"I'm not going to mount you Jacob. You're the man. You're my big brother. I want you to lay me down on this bed and take me. Take me for yourself. Fuck your baby sister. Take your prize." she said. She was getting off on this.
Something about that last phrase made it click for Jacob. The taste of her saliva, she smell of her body, the sound of her sweet angelic voice. He got up and lay her down on his bed and kissed her deeply, sticking his tongue into her mouth for the first time. She didn't know how to handle this so she just closed her eyes and let her brother kiss her how he wanted as he explored her mouth and the underside of her tongue, tasting her sweet kiss in a way he never had before.
He pulled off of her mouth and made his way down to her neck, laying kisses on throat, her shoulders, and finally, her breasts. They were the breasts of a mature young woman but clearly they weren't done yet. He kissed her nipples gently and continued to kiss her until finally he reached her completely shaven mound.
"You shaved for me?" he asked.
"I wanted you to see me completely bare. At the first time." she said.
This would be the moment of no return. To touch her here. To taste Cassie's pussy. Even that phrase "Cassie's pussy" felt wrong to him in the moment. Cassie was the girl he had raised. His little sister. He remembered every moment with her.
But as he settled his gaze between her tight thighs and looked upon it, he knew that whether it was wrong or right, his baby sister was giving her virgin, tight, perfect little pussy over to him. And as he gazed upon it, her fleshy outer lips framing her tight inner ones, her pussy dripping a sweet white cream onto his bed in a little stream, he inhaled deeply, absorbing the aroma of Cassie's vagina and her arousal into himself.
Breathing it in, he knew had never experienced anything as perfect in his life. It was strong, powerful, intoxicating. It was everything he'd ever need. All the images she'd painted of bearing his children, giving him pleasure - all of it flashed before his eyes as he looked at her tight, wet pussy dripping for him.
"Go ahead. It's yours. It's always been yours. It was created for you and only you." she told him, her hand brushing through his hair.
Jacob inched forward and kissed her gently on her inner labia, slipping his tongue and tasting her for the first time. It overwhelmed him how wrong this was, but how wonderful she tasted - sweet, sour, sultry, sexy, an indescribable taste of the white nectar of his little Cassie, as her juices trickled onto his tongue and into his mouth. He slowly began to stick his tongue all the way into her pussy, a part of him entering her body here for the first time. It was too much for her as she wrapped her thighs around his head and bucked her hips. She had never been touched here before by any person.
"Oh God!" she screamed, never having known what it's like to be rubbed in this sacred place.
Jacob slowly pulled back, his lips wet with Cassie's honey, his mouth full of her taste. Something about her pussy, tasting it, had aroused his desire in a way he had never felt before. He needed to take her. He needed to claim her. Her quickly sat up and lined himself up with her pussy, and began rubbing the massive head of his engorged cock up and down Cassie's wet cunt lips. He looked down to see her wetness on his penis. Such a forbidden thing. So wrong to see the glistening shine of her baby sister's most private juices covering the head of his cock. He almost shivered with the thought of what he was doing. But there was no stopping now. Still, he had to ask.
"Cassie...sweetie...are you sure? We'll never be the same again." Jacob said.
Cassie's eyes welled with tears. "I never want to be the same again. I love being your baby sister. I love that you raised me. I love that you took care of me. But I want this now. I want us to change into this. You aren't my Father. But I want you to be the father of my children."
"Oh my sweet Cassie" Jacob said, he leaned over to her face, his cock still nestled in the inner lips of her pussy, and he kissed her gently.
"I still have my hymen Jacob, you have to go slow." she said.
"Of course Cas" Jacob said.
A part of him still struggled. So much of this was desire. She was a young, fertile, virgin, sexy, tight, gorgeous, perfect little 18-year old girl submitting herself to him. Was he thinking with his cock? Of course he was. But what did his heart say?
He continued to rub his cock up and down her lips, teasing her pussy, as he processed this. What did his heart really say?
She was the most intelligent girl he had met in his life. She was responsible, kind, hilarious, loving, nurturing. She was all the things a man would want in a woman, he had just never seen her that way till recently. A part of him had always raised her to one day have the values needed to be a good wife and mother. He had taught her how important family life is. How important it was to choose a career that allowed her to be there for her family. How he had given up other medical specialties so that he could be home every night for dinner.
He looked at his sister's tight stomach, his abs barely visible underneath her smooth pale skin. He imagined what would be like to kiss her stomach while her womb was full, bearing his child. That image is what sent him over. He knew that he would want any children he had to be like her. To learn from her. He wanted her to be the mother of his babies. His partner. His friend. Just like now but so much more.
He looked her in the eyes. "Ready Cas?"
"Yeah baby, I'm ready." she said.
He slowly inched himself, just the head past the entry to her pussy, feeling the tightness of her cunt squeeze him hard as it popped inside and then he felt it, a clear barrier that denied him entry. Her seal. Her hymen stood guard.
"Oh fuck that felt good" Cassie said, just getting used to the feel of his head inside past her cunt lips.
"I can feel you touching my hymen Jacob." she said.
"Do you want me to push through at once or take my time?" he asked.
Can you just pop through it, but then not put all of yourself in me at once? Just pop it and then stay there. I don't think I can handle all of you immediately." Cassie said.
"Of course bunny bear." he said. And then caught himself. That was his nickname for her for many years, he had only stopped using it recently.
"Sorry Cas, that's probably not what you want to hear right now." he said.
"No Jacob". she said, as she adjusted herself a little to deal with the pressure on her hymen from her brother's massive cock. "It's not like that at all. I am your bunny bear. I'll always be your bunny bear. You know, nothing is changing about us in terms of you being the man who raised me. We're adding to our relationship, not taking away from it. Call me your bunny bear. Call me your princess Cassie. Say it while you fuck my pussy. I'll always be all those things to you. And more."
"Fuck that's bad. But you're so tight." Jacob said.
"Just blow through it Jacob, but not the whole length, just pop my cherry." she said.
"Here it is sweetheart" he said as he gave a strong thrust against her hymen and felt 2 inches of his cock force past it and embed inside her tight virgin tunnel.
"Oh FUCK!" Cassie screamed out at the top of her lungs. "OH GOD!" she yelled, in pain, but feeling a certain pleasure deep in her loins as she finally felt Jacob enter her. Her eyes welled with tears from the sharpness of her brother's penetration, but she realized she was also crying out of emotion.
"Are you OK?" Jacob asked? He only wanted to break the seal as she had asked. But her plans had changed.
"Don't FUCKING STOP Jacob!" she screamed as his massive member parted the walls of her virgin, untouched, tight vagina and invaded inch-by-inch. He felt like he could feel himself scraping across her pussy's walls, lubricated by a thin sheet of her excitement. He knew himself - she was too small for him, just newly 18, completely initiated into this. For his 8-inch penis to be her first, as thick as he knew it was - it had to be too much.
"All the way" she whispered as tears welled up in her eyes from the incredible pressure. But there was no turning back. She wanted all of this man inside her pussy right now.
Jacob thrust slowly, feeling all the textures, the muscles, the flesh of his sister's vagina grip him in a vise so tight he didn't know how it wasn't tearing her apart. It wasn't just a smooth slick tunnel, but he could feel different parts of her compressing and pressing down onto his cock as if it her life depended on it. He had never in his life made love to a woman whose pussy felt this good.
"OH FUCK! KEEP GOING!" Cassie screamed as Jacob looked her face. It was alternating between a desperate desire, a smile, tears, and pain followed by desire again. She never once left his gaze. He gripped her hips in his massive hands as he drove into her until he finally felt his pelvis flesh-to-flesh against hers. He was balls-deep inside Cassie. His little Cassie.
"Oh My God...Oh my fucking God. Jacob!" she whimpered.
Jacob immediately met her lips with his own, exploring her mouth as she sucked on his tongue. As they made out, he slowly withdrew himself from her tight grip till only his tip remained in her, and slowly penetrated her again completely as she moaned into his mouth. They continued this dance slowly until he was fucking her as a solid pace, her juices forming a thick coat of white on his massive cock.
He withdrew from her lips and she instinctively drew her legs around his back. He was fucking her. It's everything she ever wanted.
"Fuck yes! Oh Jacob it's so good. I had no idea it was so good!" she began to moan.
A thousand things went through his mind as he increased his tempo and watched her face rush with red and her moans became louder. The fateful night she became his charge. All the PTA meetings he attended. The stormy nights and messes and homework help. Her she was, a woman, his woman, giving him everything.
He watched as her breasts shook while he increased his tempo. This was turning into more than a gentle lovemaking. He was fucking her raw. He began to pound into her pussy, his massive size advantage causing her feel everything. He was reaming out her pussy and she had no idea this is what it would be like.
Every inch of her was on fire.
"He's a fucking god" she thought to herself was he watched her muscular big brother slam into her petite body and felt every inch of him violate her to her absolute limit. She felt her desire try to make her thrust back but it almost didn't even matter. As small as she was compared to him, and the fact that at this point he was grabbing her hips and thrusting HER towards him and himself into her, she was just being fucked at this point.
Her brother's expression remained full of lust but also had a gentle smile on it. He wasn't just loving the feeling, he LOVED that it was her. She could sense it. Feel it. She surrendered completely. His sweat dripped from his forehead and mingled with hers on her skin - on her breasts, her neck - a forbidden mixture. He continued to look at her face and appreciate every inch of her. Every expression. All the years of their lives together passed through his mind he felt her lust for him as her vagina closed down on his massive invading cock.
He looked down to see the point where he disappeared into his little sister's body to find his cock covered in a thick layer of her white honey. It smelled like sweet, salty lust. It was perfect. He could drown in it and die a happy man.
"Oh God Jacob! Fuck! FUCK! Something's happening!" Cassie began to moan and he began to hear her elevate her voice until she was screaming in a pleasure she had never imagined. "DON'T STOP JUST CUM INSIDE!" she yelled as she wrapped her legs tighter around him.
"Cassie! Oh honey! Oh baby! Oh fucking shit!" Jacob moaned as he felt his sister's pussy begin to massage his cock in a way that he recognized from experience with other women. She was about to explode.
"Ahhh! Oh MY GOD!" Cassie yelled at the top of her lungs as her vagina began contracting unyielding around her brother's massive penis. She felt like every inch of her was full and if he were any bigger he might split her in two - it hurt in such a good way.
"Take that cum Cassie. Take me. Take me you sweet fucking little thing!" Jacob exclaimed as he felt a tightness around his cock he had never felt before. And he realized what was about to happen - he was about to inseminate Cassie - his little sister. The daughter of his mother and father. He was about to fill her with his load - an act that could never be undone. He might hate himself, but at this moment, there was nothing on the planet he wanted more than to unload every single ounce of himself into his Cassie.
Cassie began squirting all over him as she climaxed and Jacob followed her immediately as he felt his balls lift and move and his orgasm hit. It was the most pleasure he had ever experience in his life and he locked eyes with her as she came. The first heavy, massive load of his semen fired out of his cock, embedded completely inside Cassie and filled her. More and more of his essence, thick, white, heavy, and full of his seed invaded his sister's vagina and seeped into every corner and crevice of her most secret chamber.
He usually ejaculated heavy but this orgasm lasted three or four times as long as usual. They both looked into each other eyes as they came, and he couldn't help but embrace that what they were doing was always going to be wrong, and always going to be right - and there was nothing that would stop him from pleasing this woman.
"Oh My God Baby" Jacob exclaimed as the final volleys of his cum exited his cock and became part of his baby sister's body.
"That's what sex is? Holy fuck. That was amazing. Oh my God I'm so glad I didn't do that with anyone else but you Jacob. I don't want any man to ever do this to me except you." she said as her breathing relaxed.
"I can't believe we just did this." Jacob whispered as he kissed her shoulder, his full length buried inside her with a full load of his cum.
"Oh motherfucker we are doing this for the rest of our lives." Cassie said to him.
"Language" Jacob said, smiling.
"Should I call you a sisterfucker instead? she said, laughing, causing him to chuckle into her shoulder as he kissed her.
"So honey I need to pull out and my cum is going to pour out of you and all over the bed." Jacob told her.
"Won't it all go into my pussy and stay there?" Cassie asked. Her innocence made this....conquest...so much sweeter. That he was going to be her teacher, her guide, and the source of all her pleasure made him so happy.
"No Cas, cum always pours out after sex. And I came more than I ever have in my life. I wouldn't be surprised if my load is knocking you up right now. I'm going to use my t-shirt. Just lift your butt up a little and I'll put it underneath and it'll drip out.
Their creampie dripped out of Cassie's vagina as soon as Jacob pulled out and pooled into his t-shirt.
"Can I taste it?" Cassie asked.
"Taste what? Our cum?" Jacob asked.
"Yeah, I want to lick it off your shirt. It's me and you together. It has to be good."
Jacob gave her the shirt and she licked the heavy load off the shirt and held it in her mouth for a few seconds before swallowing.
"Damn. That's different. But it's so good." Cassie confessed. So right now I have your cum in my pussy and my stomach. You're really taking over my body big brother."
"Are you OK Cassie?" Jacob said. As they lay on the bed with her head on his chest, all he could think about was her well-being."
"I feel like I just got off a horse....but if you mean do I feel OK emotionally...I've never, ever been better in my entire life. You're everything I ever wanted and I had no idea this would be so good. I'm yours forever Jacob. Promise me."
"Of course - you're mine forever, and I am yours." Jacob responded.
"Good." Cassie said as she yawned. "I'm really tired. I need to sleep."
"You can sleep here. I'm going to go wash up." Jacob said.
"No washing. My pussy cream stays on your cock all night, with my sweat and everything. I want your cock to absorb it, to absorb me."
"OK sweetheart." he said, as he held her tighter and pulled the covers over their intertwined bodies.
He had never imagined this could happen but now that it had, there was no turning back. He fell asleep with his little Cassie in his arms, head on his chest - both like so many times before but also like no other time before.
"There's no way I didn't just knock her up." he thought to himself as he fell asleep to the sound of her gentle, regular breathing and the feel of her entire body snuggled into his.
