You begin your plan

By the time you finish your extensive research, the sun was lowering. You had downloaded all relevant information and neatly sorted in a heavily coded file. You stand up from your desk for the first time in several hours and stretch. Several of your joints pop and you cant resist groaning. It was also the first time you noticed the stench radiating off of you.

It was unbelievably hot. It was mid July so you weren't surprised. Luckily, your computer was water cooled, or it would've had overheating issues. You grab a towel and strip out of your boxers, throwing them into the basket by the door. You decided to just leave it hanging since your sister was gone.

You cross the hallway, headed for the upstairs bathroom. You shared the bathroom with your sister, while your parents had the much larger master bathroom. You step inside your bathroom and hang your towel. You turn on the shower for a cool temp. Just enough to cool down from the summer heat. You hop in and just bask in the cool water.

You lose track of time for a little bit. After a few more moments, you turn off the shower and dry off. You hang the towel around your neck and walk out. Just before you reach your door, Lora walks up the stairs.

"Oh! Hello honey, did you have a good shower?"

"Yeah. I love the heat, but there is a limit."

"No kidding! I hope Sarah gets more comfortable with us and herself. I wish we could just walk around naked. I see your talking advantage of Sarah being at school." She smirked, You'd say she snuck a peak, but her gaze lingered a bit.

"Anyway!" She continued, "Do you have any laundry I can clean?"

"No thank you, I can do it myself."

"Alright, the detergent is in the top left cabinet of the laundry room."

"Alright thanks."

You bid farewell and decide to get started on your plan in the next hour before Sarah would come home.

Using your knowledge from the previous world, you make a few calls, do some coding and further research.

You become so focused that when a knock comes from your door, you don't even think about calling them in. You hear the door open, but you are on a call and don't look. You hear some things being moved around. After a few minutes, you finish up, happy with your progress. You spin around happy and stand up in joy. You were making great progress for only a day of work.

You quickly realized that were weren't alone. Your mother and sister were in the room. By the looks of all of stuff, your Mom was helping Sarah move her things into your room. And you had yet to put on boxers. You froze, your mind from your old world took over, where it wasn't normal to be naked in front of your family. In a small part of your mind, you recognized that this is the second time today that you had unintentionally flashed your family members and really hoped that it wouldn't become a habit.

Sarah had changed back into her panties and over shirt. Your mother wore her typical lingerie, a deep blue pair. Panties that clung to your mothers tight ass, emphasizing the beautiful shape of her ass cheeks. Her thin waist showed off her large E sized tits. You would never have known that she had given birth to two children. When you had compared her to supermodels this morning, you weren't kidding. She had a gorgeous face with long dark hair.

Your mother had covered her mouth with her hand, but you could tell that she was smiling. Your sister, on the other hand, was bright red and frozen. Your mother quickly notices and takes advantage. Before you can react, you mother gets behind Sarah and pushes her towards you. On instinct you catch her, unfortunately for her, and amazingly for you, that causes your already erect dick to rub against her stomach.

Again, with amazing speed and dexterity, you mother swipes off your sister's underclothes right off of her.

"Mother!" You call out too late. She had already retreated from the room, and by the sound of it, had already locked the room from the outside. From your memories, you knew this was the first time the outside lock had been used.

"MOM! That's not right!"

You are distracted from your protesting by your sister squirming in your arms.

"Sarah, do you want me to turn around while you hide under the sheets on my bed?" You ask while looking straight up.

You think she didn't hear you but after a moment, she quietly responds, "No."

You thought you had misheard, "What?"

"Dad was right."

"About what?"

"That I like you and more than just as a brother."

You finally look down at your sister. Hearing those words, and seeing and feeling her boobs pressed against your chest, send yet another rush of blood to your little brother. Sarah felt it, but didn't shy away, in fact, she seems to snuggle closer.

"Sarah?"

"Yeah?" She responds, her face still jammed into your chest.

"Look at me."

She hesitantly does so. You don't hesitate. You lean down and kiss her. She lets out another cute yelp, but doesn't resist. After a moment, she repositions herself to kiss back. For several minutes, you make out, and everything is right in the world for those minutes. Surprisingly, she took the initiative. One moment, you are just engrossed in kissing your little sister, and the next you feel her hands on your dick.

She pulls away from the kiss, "I want you," she gasped, "In every way you can."

You lean down to whisper in her ear, "And I want to give you everything I can. And I want to give you it over and over again."

She moans, before pushing you lightly towards the bed. "Lay down, I want you in my mouth."

In a daze, you do as she asks, but before she can approach you; you ask that she stops.

"Why?" She sounds worried, almost horrified that she had done something wrong.

"I just want to see you in all of your bare beauty."

She complies and holds her hands behind her back, moving her left foot behind. The position displayed her well endowed chest, but hid her clean shaven, gorgeous, virgin pussy. You don't think your dick could have gotten any harder. You laid down, your dick sticking straight up. Sarah took this as permission and moved forward.

Almost frenzied, she fell to her knees. She slowly pulled your knees apart, giving her room to scoot closer. She grabs your dick, almost reverently. Sarah angles her prize towards her mouth, and as she opens wide, you notice that her mouth was literally watering. You had little doubt that she had been wanting this for much longer than she would admit.

As she begins her blowjob, you can tell that she had practice. She never had a lover before, and she was too shy to buy her own sex toys.

"Sarah, did you take one of Mom's toys to practice on?"

She lifted her head, gasping, but with joy, "Yeah, though I think she always knew." She responded before desperately sucking again. "You didn't only use it in your mouth did you?"

"Nooo," She was so excited and happy that her words seemed to be slurring, "I used it everywhere. In my mouth, in my vigina, even in my ass."

"You imagined it being my dick didn't you?"

"Every single time. Sometimes I would use it near you, hoping that you would catch me. Hoping that you would gently take the dildo out, and then roughly plow me with your dick until I am begging for you to put me in a Cumming Coma."

"Oh you like it rough?"

"Yeeeeeeeeeshh."

"Then prepare yourself, because I want to see how well your training has paid off."

She only has time to raise an eyebrow before you grab her head and jam it down your dick. She obediently opened her mouth wide and relaxed her throat. As the head of your dick reaches the entrance to her throat, she begins to gag, but before you can pull back, you feel her hands on your ass, not allowing you. She instead pulls you deeper.

Her gagging continues, and it quickly becomes a mess of saliva. You pull out to give her a breath, but she only takes a few gulps of air before she devourers your dick again. It isn't long before you are skullfucking her. Once again, you pull out. Before she has the chance to pout, you stand up, pick her up, and toss her on the bed feet first. As she is recovering, you pull her closer to the edge of the bed until only her head is dangling. From here, you continue to skullfuck her. The only sounds she makes is the now occasional gag, and moans.

You slow down slightly, and lean forward, towards her untouched pussy. Its already drenched before you even have the chance to get to work. She just moans louder as you begin to eat her out. In both of your lives, you had never eaten someone out. You had no idea what you were doing. Yet, if her sounds were any indication, you were doing something right.

She lifted her hips, enticing you and driving your tongue deeper. After a few minutes, you are reaching your climax. You pull away, your dick sliding from your Sister's mouth with a pop. Before she can question, you grab her hips and spin around, bringing her pussy to the edge of the bed. You kneel down and resume eating her pussy. It isnt even a minute later that she cums, hard.

Her entire body spasms, her legs wrapping around your head, shoving it into her squirting pussy. After nearly two minutes, her legs relax, allowing you to escape. As you are gasping for breath, you notice that she is still occasionally spasming. You remember reading that women's orgasms could go on for several minutes, but you had never imagined it being so violent.

You sit next to her as she continues to occasionally twitch, her eyes rolled into the back of her head. You stroke her hair, patiently waiting for her to come back down from the climax. Eventually, she regains consciousness and looks up at you. The look was of one of devotion.

"Kyle, that was the most amazing thing ever!" She says between gasps.

"I'm glad I was able to give it to you. How are you feeling?"

"I cant feel my legs and my throat is sore."

"Sorry."

"Don't be! I wish my legs weren't so numb, but its just proof that it was so great. And my throat is a good kind of pain. I never thought I would enjoy sucking your dick so much. Wait! You haven't cum yet have you?" She exclaimed as she clumsily gets to her elbows to look at my dick, still as hard as steel.

"No I haven't, but you are too tired. We can continue this again later, if you want. I know I want to."

"Don't joke! We are going to do things like this regularly after this, but this is our first time together! It wouldn't feel correct or right if we both didn't finish."

"Sarah, I love your dedication to this. I'm ecstatic that you want to keep doing these things. But you can barely lean up, let alone stand."

"So what? Kyle, look in my eyes."

You do so, leaning close enough to kiss.

In almost a whisper she says, "I want to use me as your personal Fuck Toy. Fuck my virgin pussy, or my virgin ass. I've trained both to take a dick. I want you to use me, I want to be used. Please, use me, Master."

Your dick had slightly deflated during this break, but at her whispered words, it pops right back up. You can only nod to her. You get off the bed and grab her thighs, pulling her closer to the edge of the bed. You push her legs up and over Sarah's head. Her ass and pussy were presented to you.

You line your dick up to her pussy, not yet taking your prize.

You look at Sarah in the eyes, "I love you Sarah."

"I love you too, now claim me as you woman!"

You thrust forward. It was tight, but was so wet that you slid in easily. Women naturally loosen when doing it with someone they like, but Sarah had never done it before. Her pussy was brand new, still naturally tight, but was very quickly adapting to your shape.

You begin to thrust slowly, watching her reactions. After a few moments, after seeing that she isn't in any pain, you speed up. She begins to moan quite loudly. You would've tried to keep her quiet, but you had no doubt that your Mother was listening at the door and very proud of herself for causing this.

Soon you are a blur, you are moving so fast in and out of your sister.

"Yes! Fuck me! Fuck my tiny pussy! Make it submit to your dick!" She shouts.

You let go of her legs, letting them rest against your chest, as you grab her bouncing tits. Lightly squeezing them, Sarah moans even louder. Lightly pinching her nipples brings a new round of moans. You decide to silence her by kissing her. Her arms wrap around your head. You remain there, kissing her while you grope her tits and fucking her. You stop kissing her, letting go of her perfect tits to prop yourself above her. She entangles her fingers together, keeping them on the nape of your neck.

You continue to piston her, and after a few minutes, you feel yourself close to finishing. As a final act, you lean forward, close to her ear and whisper, "You are mine. No man is allowed to touch you without my permission. I am going to cum inside of you and give you my child. And when you give birth to them, I will fill you with another, and another, and another. You are forever mine!"

That seemed to set her off again, perfectly timing her orgasm with yours. Her legs were too tired from the first orgasm to wrap around your hips, but you felt them wrap around your calves. Her eyes roll back and she screams in ecstasy. You groan and moan as you unload what feels like a gallon of cum into her waiting pussy.

Once you both finish, you nearly collapse on her, but barely manage to lay next to her. Both of you try to catch your breath, and lay there for several minutes.

Finally, while staring up at the ceiling, Sarah says, "You pumped so much into me that I can still feel in leaking out."

You chuckle, which causes her to chuckle with you. You both lay there for several minutes in your afterglow.

"Hey Kyle?"

Her tone was serious which brought your full attention, "Yes Sarah?"

"Do you mean what you said?"

"About what?"

"About me being your woman?"

You don't hesitate, "Yes, you are mine forever, or until you decide you have had enough of me."

"Fat chance of that happening. I'm glad. I've loved you since before I understood the word." She snuggles in close and you wrap you arms around her.

"The feeling is mutual and always will be."

She sighs in relief and relaxes in your arms. For a few moments, all is right in the universe.

"Hey Kyle?"

"Yes?"

"Did you mean it when you said you wanted to impregnate me?"

"I said that because I thought it would solidify the idea that you are my woman and push you over the edge, which it did I might add. But I don't know. I mean, I think I would like kids, but I haven't put any actual thought behind it. But right now, I think that we aren't ready for kids. I mean, we JUST got together. I think we should take things one step at a time for now."

"What about in the future?"

"Sarah, do you want kids?"

"I think I would... Yeah, I do want kids. I want to have my own family one day."

"Then so do I. I'll fill you up as much as I can until we have as many kids as you want."

She blushed, but kept silent. It wasn't long before you heard the steady and slow breathing of her sleeping, and you shortly followed suit.

*****

As you and Sarah slept on your bed, your door quietly opened. Your mother tip toed in. She got closer and observed the aftermath. She saw the pool of cum under her daughter and saw that her daughter's newly broken in pussy was still leaking. The scent of it made her mouth water and she had to stop herself from eating it all out of Sarah pussy. She studied how Sarah was cuddled up against you, with your arm holding her close. She saw the serene looks on both of your faces and couldn't help but smile lovingly.

She was about to leave the room before she saw that your dick was hard again, and pointed to the sky. As much as she tried to stop herself, she couldn't. She moved closer and grabbed your large dick, absentmindedly stroking it. She leaned close and took a deep sniff, smelling your dick, your cum, and Sarah's pussy juices. A bit of precum leaked out the top of the head and she licked at it, tasting everything of your earlier actions.

Your Mother instinctively put a hand down her thin panties. She almost started to give you a handjob when a noise from downstairs spooked her out of her trance. She quickly realized what she was doing and quickly left the room, turning off the light and closing the door as she left.

Outside the room, she leaned against the wall and sighed. She inserted two fingers into her soaking pussy before she held them up to her eyes and pulled the two fingers apart, see her juices string between the two. She put the fingers into her mouth and licked them clean.

Your mother sighed, as she thought, "My husband isn't even dead yet and I'm already lusting after my son. Daniel may have instructed us that we would be Kyle's women when he died, but he wasn't dead yet." Your mother wanted nothing more than to go to you and wake you up so you could fuck her brains out. She would've went to her husband, but the disease had taken his libido and ability to get hard last month. She was beyond horny. The radiation from the wars had altered women's genetics, making them naturally more horny, and your mother was naturally more horny than other women.

She couldn't go a single day without being fucked. She had staved it off temporarily with dildos and other toys, but it wasn't the same. She wanted, needed, to get railed by you, but she had promised Daniel that she would be his woman until he died, and she refused to break that promise.

Your mother shook herself in an attempt to calm herself, failing to do that, she decided to take a cold shower. She knew it would do nothing other than temporarily suppress the urge, but she didn't know what else to do. As she left the hallway, you heard her receding footsteps. You had been awake the entire time.

"Interesting." You commented before kissing your sister lightly and returning to sleep.
