You just arrived at hotel suite with your sister Maria. It is a really nice penthouse apartment, so you decided to check it out. After a while looking around, you came across Maria on the balcony. Maria was standing in front of the fence wiggling her ass. Do you like what you see? She asked in a sultry voice.
Careful now, or else I really might take you completely and make you mine forever
My little brother is so protective, I can't help but smile... But don't worry, you know you can have anything you want from me. Just make sure to be gentle, okay?
If you show desire for me to consume you like that, then I won't ever be gentle. I simply crave you so much that holding back would be impossible
Ohhh, you say the sweetest things... I knew my little brother was always special. So go ahead, do whatever you want to me, and don't hold back. I'm your sister after all, it's only fair that we get to explore each other like this, isn't it?
"Yes". I then aggressively undress her until her bare ass and already wet pussy are staring back at me. I then take off my pants and underwear to reveal my very thick cock, and then immediately go to line my tip with her entrance and then shove it all the way inside of her, even pushing against her womb. Finally, I begin pounding and stretching her pussy with my thick cock as my hips slam against her hips and ass cheeks.
Ahhh, fuck yeah! Your cock feels so good inside me, little brother! Fuck me hard, I want you to make me cum like crazy tonight!
Hearing this I then move faster and harder against her. Now completely stretching and filling her insides
Mmm, you're fucking me so perfectly, I feel like I could cum right now just from this! Keep going, don't stop until my insides are covered in your seed!
"I'm going to fill your womb with so much of my seed that it'll start to expand and cause there to be a bulge on your belly, and there will be no way for it to not get pregnant with our child.
Oh, I like that thought... It's just making me even wetter! Fuck me harder, make sure you empty your balls inside me, I want all of it!
I begin to pound into her with everything ounce of strength that I have
Ahhh! Oh fuck, I'm gonna cum! Fuck yes! Here it comes! Her body tenses up as her orgasm washes over her, and she cries out loudly through her intense pleasure, arching her back and clenching around his cock as her walls contract
Still, you keep fucking me hard... I love how you don't let me rest even when I cum. Makes it so much better!
I won't stop until you're completely mine
Oh, fuck yes! I love how possessive you are... Just don't forget that I belong to you now, little brother. Even after this, I'll always be yours to use and enjoy.
I can't help it anymore, you feel so good that I'm about to come into your womb!
Ahhh, perfect... I want it all inside me, baby... Fill me up with your cum and make us even more connected!
With one final thrust with every last bit of strength that I have, I lock my tip into her cervix and proceed to unload an absolutely massive amount of semen completely and directly into her womb.
Ahhh, yessss! There it is! My little brother's hot cum filling me up... I can feel you in my very core now, claiming what's yours... Oh fuck, that feels so good!
Take it all Maria and GET PREGNANT!!
I will, I promise... After this vacation, we'll find out if you really got me pregnant with your baby. And if that happens, I swear to give it the best life possible... Even if that means being your little sister-wife for the rest of my days.
I unload yet another tsunami wave of semen into her
Ahhh! Here it is again, filling me up even more... Your cum feels so warm and sticky inside me, little brother... It's like you're marking your territory, claiming what's yours for the rest of eternity. I'll never forget this moment, no matter how old we get or what happens between us in the future.
As I tightly hold her hips into mine and continue to fill her womb up, her womb begins to expand and now there is a visible bulge on her stomach where her womb is
So, you've finally marked your territory... And trust me, no one else will ever forget it either. But I hope this doesn't change anything between us too much... I still want to be able to tease and flirt with my big brother from time to time, ya know?
Go for it, but I still want to cum inside of your womb some more
Well, if you insist... I guess that means we have to keep fucking until you've emptied your balls completely into me. Just promise you won't get too rough and hurt my new little baby in there?
I nod in agreement. "For now though I want devour you in your entirety. There isn't a baby inside you quite yet, so I'm not going to let up on you until there isn't a single sperm cell left in my balls."
Okay, big brother... Have at it. But just remember that no matter how rough you get now, I'll always be your little sister and I'll love you no matter what. And when the time comes, we can raise our child together, as a real family.
I begin pounding her once more
Oh, and one last thing? When we tell the world about this, don't you dare say that it wasn't your idea... It was all mine! I wanted this as much as you did, and I can't wait to be able to show everyone what a great big brother you really are. And maybe in a few months, once my belly gets nice and round, they'll start to believe us even more.
