Fuck

Your door creaks as you slowly open it, looking with one eye at the living room, you heard mom and dad go out a couple minutes ago and your brother is playing a game in the TV, laying back on the couch, perfect position for your new devious thoughts. After yesterday's life altering orgasm you haven't been able to take your mind off of him, the wait makes you wild and it's a shame he only seems to have one load per day, you wish you could be filled anytime you wanted even if the possibility of getting pregnant by your own brother terrifies you.

You close the door as slowly as you opened it, and once it clicks shut you quickly get undressed down to your naked body, just how he likes it, before opening the door wide open and leaning seductively on the frame, he doesn't even look at you.

"Hey, John"

He doesn't react at all, so after you grab some napkins you go over there and sit on his lap, with your legs to his sides and your pussy aiming right for his crotch.

"What do you want?" his bluntness hurts your feelings.

"I want you inside me"

"I'm not feeling like it today"

"But you started this! Also, you're a guy, feeling like it all the time is your whole thing!"

"But I'm playing right now"

"That's not an impediment for me, I want you now"

You try to entice him with your eyes but he doesn't even look at you, he just pauses the game to use his dominant hand to unzip his pants.

"Alright, give it a try"

You immediately start rubbing his cock, it quickly gets erect but not a muscle in his face moves, it's almost like a reflex that he didn't even notice, you quickly put it inside you and start going up and down on it, going slow like he did to you yesterday but he doesn't even blush, he just keeps gaming.

"Come on, you know you love this"

You start bouncing on it faster and rubbing his abs, he gives you a small smile but it's most likely just him being ticklish, you stop rubbing him and focus on bouncing on his cock, you go faster and harder but he just doesn't react, you kiss him passionately but he quickly pushes you away.

"You're not letting me see"

"Come on, you know you love this" you're breathing heavily.

"Oh yeah, this feels soooo good" he says in a monotone voice, you love him now and he mocks you.

You keep going hard and fast until you quickly find yourself on the edge of orgasm, and given your speed, the only thing you can do is brace for impact.

"Oh"

The pleasure runs through your every nerve, you almost squirt but you are barely able to contain it, not wanting to soak the couch, holding the dam closed only makes you feel the orgasm harder, your whole body shakes and your torso falls forward, hugging John and pressing your face against his shoulder, muffling your moans with his shirt.

After your orgasm goes away, you lift your head to see him blushing, looking right at your mouth with thirst, your shaking against his body must have awoken his manly instincts, he pauses the game and puts away his controller.

"Okay, now I'm interested"

Without another word he grabs you by the hips, flips you around to get a good look at your ass and slaps it before putting his dick back inside you, as you start to bounce on him he reaches around to stimulate your clit, no doubt trying to bring you to another orgasm.

"Please never reject me again" you say, breathing heavily, the sound of your voice is seasoned with the sound of your legs slapping on his and the occasional ass smacking.

"I will never, Jane"

Right after he says this, surely because of his pervy sister kink, he dashes through the finish line even though he wasn't even close before, grabbing your ass and pulling it down before cumming inside you as he moans, you moan even louder feeling his hot cum painting your insides, you quickly grab the tissues to catch the drops of cum that roll down his cock as his balls pump inside you, it's in this moment you wish you weren't on birth control, to be sure that one of these fuck sessions leaves you as the mother of his kids.

"I bet you hated that" you mock him like he did to you yesterday.

"Oh, you'll hate this"

He barely even gives you time to put away the tissues before he grabs you by the hips, slamming you back first on the couch besides him, you instinctively open your legs for him but he then lifts them up until your knees almost touch your tits, leaving your pussy looking up, he gets on top of you and quickly slides his dick in, a sensation that you'll never get tired of, after he starts pounding in you, he looks straight into your eyes.

"There's something I have to tell you"

Your horniness doesn't allow you to get worried about that.

"About what?"

"Your pills"

His cock is starting to scramble your brain, the build up to a second orgasm is pure ecstacy and won't let you think.

"Ok, so what?"

"They're not birth control, I swapped them a couple weeks ago, they're another medication"

"And what are they?" you're completely disinterested, not even registering the fact you're not on the pill.

"Fertility pills, they cause perpetual ovulation, they make 40 year olds extremely horny and fertile, and it clearly did a number on you"

Your eyes open wide, his cock is looking right at your womb and threatening you with everything you could ever dream.

"So?" you are getting close and his voice is the sexiest sound you have ever heard.

"You know what they call this position?"

"I don't"

"The mating press, do you know why?"

Your heart is about to burst out of your chest, you're right at the edge and keeping yourself from bursting is the hardest thing you have ever done with him pushing you this hard.

"Why?" you moan, you close your eyes in your delicious ecstatic ****.

He responds with a moan, his cum pumped into you and pushed even harder by gravity, you would expect him to have less in him after the last creampie but he's filling you with an even bigger load now, drowning every part of your womb in in his virile cum, you can't help but burst on him too, shaking and hugging him, digging your nails into his back, wrapping your heads around his hip and pulling him in with all of your strength, biting into his shirt to muffle your now screaming moans, you squirt all over his crotch with a bunch of it falling onto you too, when your moans start going down in volume he pulls you away from his shirt and into a passionate kiss that makes you see fireworks, you look into his eyes and see his almost heart shaped eyes, loving you deeply.

He slowly pulls out, making sure not a drop falls onto the couch, he pushes your legs further up so that your vagina is completely vertical.

"I have been taking male fertility pills too, it was hell looking at the videos you posted with your newfound horniness and not being the one to cum into you"

"It must have been hell to not be with your little sister"

"I tried putting my cum into your lube container, but after the first couple of weeks it was clear that if I wanted you pregnant I'd have to pump it myself"

"And I love you for doing that"

You give him a last kiss before he gets up to look for tissues, you're left there grabbing your legs to keep yourself from spilling his seed on the couch, thinking about how much time your little egg is spending drenched in his creamy cum makes you so horny, surely if he didn't breed you before he's definitely doing it now, but at the same time you want to spill it all over the couch, you want the whole world to know that you love him, that he loves you, and exactly how you got pregnant, but sadly they may never understand.

When he gets back and lets you let go of your position, only a small drop rolls out of you, the rest of his massive load surely stuck to your insides, a final nail on the coffin of your past life, you're now solely the mother of his children, you couldn't be happier, you give him a long passionate kiss and he kisses you back, you end up making out for a while on the couch, not even caring about when your parents will come back.
