Sorry for the delay. I'm taking my time with "I am Morty" fanfic because I didn't expect to enjoy it as much as I did. But that's how it is.
I'll try to keep you guys updated with this fic but I try to avoid being burned out because it ruins my chances of writing.
Anyway, Enjoy! Toodaloo Bitches.
=========
Mitsuri laid on the bed looking at her man who is currently going to personally devour her without anyone joining. It was only him and her. A man and a woman. She can't deny it makes her sad, but having moments like that makes it worth it.
"Allow me.....Ryuu.~" She breathed out, reaching down her body to pull off her panties after lifting her legs into the air. Her soft, dainty foot wagged in the air a bit as she slid the piece of fabric off till her peach pussy came into view. Ryuu's mouth watered instantly as she left it hanging off her right ankle, allowing him to spread open her legs and show her the juicy cusp of her pussy.
Ryuu slid his tongue across his lips as he grabbed the hilt of his member and guided it into the spongy velvet folds of Mitsuri's sex when he pressed himself on top of her mating-press style. Her legs bent back and her ample buttocks lifted into the air as he held back the lower half of her body with just his legs, ready to fuck her raw.
"You're mine.~" He breathed out in a husky voice and Mitsuri could only smile dreamily at him as she felt the tip of his bulbous cock plunge into her pussy slowly from above.
"Yes!~" She cried out and felt Ryuu plant his feet around her thighs just as soon as he plunged his cock down into her sex!
*Squelch!*
"Ggnnghh! Aaaaaaaagghhhhh.....!~" Mitsuri cried out in pain as she felt him plunge past her womanhood, piercing her virgin hymen and sliding his cock all the way through her tight little pussy on its way to her cervix like so. His legs hugged the sides of her thighs as he felt the gooey moistness of her tight pussy squeezing him tight as it guided him on in.
"Mmngghhh! Oohhhh...yeah! Y-You're tighter than normal...! Uughhh!" Ryuu growled, letting his eyes glow brighter as the feral lust now consumed his body with this new claim. He could feel himself getting stronger already as he wriggled his dick into the tightest chasm inside of the former Demon Slayer's pussy.
She was breathing hotly with excitement, grabbing her head into her hands as she tried not to scream out loudly in pure ecstasy and pain. Mitsuri was wanting him to start treating her like a piece of meat already as she had always secretly wanted to be treated. She could feel the bulbous head of his length prodding against her womb, demanding entry till Ryuu began bottoming out of her with gentle slams of his hips.
A gentle repetition of skin slapping against skin ensued with Ryuu, once again, dominating another female that had aroused the evil incarnate inside of his body.
He growled quietly like a monster and felt the squishy confines of Mitsuriu's pussy call to him as he bottomed out of her. His thick, bloated balls tapped vigorously against her sex, making her buttocks wriggle together with his legs as they fucked like animals right here on the snowbank without a care in the world.
"Haaaahh...aahhh....ahh...ahh...aahh..aahh..aaaahhh! R-Ryuu....!~" She cried out finding herself becoming his fuck slave and enjoying how he was focusing only to her. Still, Mitsuri showcased her carnal pleasure, having him only to herself make her incredibly happy as she continued to feel Ryuu's cock tunnel through her pussy with increasing passion as they went along.
Soon her legs rose high into the air, shaking back and forth with toes curling tightly. Mitsuri clung onto Ryuu's shoulders, digging her fingers into his skin yet feeling like she was touching hard rock from underneath it. He was strong, powerful, and always made her really feel like a desirable woman.
Unlike the man who rejected her, Ryuu didn't mind her quirks and appearances, having told her that's what he loves about her. Mitsuri couldn't make her pussy clutch harder around his length if she tried, causing Ryuu to croon loudly like an animal as he began intensifying his pace.
Rapturous noises of bodily coitus followed with his pelvis slapping away into the back of her legs and her ass very hard. Mitsuri was feeling Ryuu's cock drill it's way into her center with ease, prodding and pushing into her womb as she continued to feel the enormous pleasure that numbed her mind to all other sensations.
The squelching twitches of her pussy became even faster as she felt his dick burrowing into her like an animal's making the sounds of bodies slapping together echo out from the wilderness where they were at!
"Mmnngh..mnngh....mmngh.....mngh...mmgnh..! Grgrhh! So good! Oh, it feels so good fucking you right now! You're tighter than I first fucked you." He growled, enjoying the way her cervix squeezed tightly around his length as he continued pummeling Mitsuri's pelvis body nonstop for what felt like minutes on end, making the woman howl in euphoria she held onto Ryuu's neck with a blissfully broken smile on her face.
"Oooaahhh....aaaahhhh! Ohhhh..yess! Yesss! Uuh…~♥️uuh..uuh..uh♥️...uh..uuaahh!~♥️" She went on like this with her head tilting back and breasts bouncing around from underneath him until she eventually came explosively around his cock with a smile!
Mitsuri's pussy squeezed tightly around Ryuu's length, making him deliver a few hard slams of his pelvis onto her body until he grunted loudly like an animal and came! His balls rested against her nether region, tapping her buttocks while pulsating loudly like a visible heartbeat.
"Mmggnnghhh! Here it comes.....!!" He growled, feeling his cock bloat and spew thick ropes of sperm directly into her sex! Mitsuri squeezed her toes tightly from inside of her shoes, feeling every blast of molten warmth fill up her baby-maker in consecutive undulations of their bodies.
*Splurt...splurt...splurt.....splurt...splurt...splurt...splurt....splurt...splurt...splurt!*
"Oooaaaaaahhhh!~" She cried out again, feeling her womb fill up and bloat with enough of his sperm pumping into that some of it even started leaking out of her quim the longer this went on.
Ryuu ground his waist against hers, making sure to get every ounce of his seed into her waiting body while they grooved their bodies against each other in post-coital bliss.
He could still feel his cum pouring out into Mitsuri's womb, leaving her stuffed and thoroughly bloated with enough seed to drown out her uterus entirely.
He shivered one last time in bliss and slowly pulled out of her, leaving her gaping quim oozing his pearly essence with a dream-like smile on her face. Mitsuri was breathing rapidly with a blush on her cheeks, looking utterly fixated on Ryuu with a dream-like smile that simply told him that she belonged to him now.
"Ryuu.....!~" She cooed happily and Ryuu grinned savagely as he remained above her in an embrace with the former Demon Slayer girl, basking in the glow of another conquest and feeling his strength rise to even higher than before.
"Did you enjoy it, Mitsuri-chan?" He said and drew his long serpentine tongue along the surface of her neck while grabbing onto her right breast. Mitsuri instantly mewed with pleasure as she kept her legs wrapped firmly around his own while he rested atop of her naked body.
"Y-yes, Ryuu I love it!~" She sighed happily and saw him bring his face up to look at her, grinning confidently as he held her cheeks into each of his hands.
"That's nice to here but don't forget I am not satisfied with simple one round~"
Upon hearing this, Mitsuri nodded her head rapidly with a blushing smile of excitement before they wrapped each other's lips around one another again, this time with Mitsuri bringing her arms around Ryuu's neck in complete submission.
Ryuu's eyes lit up in red, making Mitsuri shiver with excitement as he held open her legs and guided his sperm-coated cock over to her aching folds.
With a grin and a wink, he held a hand around his lover's stunning body before pulling it onto his waist. His cock sheathed itself into Mitsuri's tight little pussy, filling it up instantly and creating a bulging impression from within her stomach!
*Squelch!
"Uuuggghhh! Ryuu!~" She cried out in ecstasy and made her toes wriggle as she wrapped her legs around his waist, embracing him in full. Mitsuri brought her hands around his neck, pulling her brother on her lips as he pushed him to her waist even further, making her feel his length touching the very top of her womb before he started bucking voraciously into her body.
Slap after slap of sex meshing with sex soon erupted with the incestuous coupling engaging in sexual intercourse while standing up from the bed.
Ryuu grunted coarsely as he felt his lover's insides coil and squeezed his length the more he plundered the insides of her teenage baby-maker. The girl kept on clutching him with all four limbs. Inside and then out, Ryuu felt the girl's sex squelching tirelessly around his length the more he bottomed out of her pussy with ravenous sexual delight.
They even ground their mouths together in an impassioned kiss, Ryuu was making use of his newly prehensile tongue and letting it coil gingerly around his lover's while tasting her saliva.
"Mmhmm! Ryuu! Mhmm...hmm.hmmmb~♥️..mhmb~♥️♥️.mhmb..mmmb...mhmbb♥️..!~" She moaned constantly and grunted with every push of his dick being sent into her womb. Ryuu held onto Mitsuri's ass with his claw-like hands keeping her ample little cheeks gripped between his fingers as he went along.
He pushed and drove his length into her repeatedly for seventeen minutes, making the girl cum one time after another with he howling loudly into his mouth the entire time. Eventually, she pulled off of his face so she could breathe some air, making her heavy moans escape her lips as they continued fucking each other while standing upright.
"Uuaahh..ahahh..ahh..ahh..ahh...ahh..aahh..aahh..aahhh! Ryuuuuuu....! I'm g-getting close! Please don't pull out of me! I...I want to feel it inside me!~''
She cried out with little hearts appearing in her pink little eyes and held onto his shoulders with ankles crossing tightly behind his back. Ryuu could feel her insides sweltering even tighter around his length as he repeatedly bucked into his lover's pubis, making her croon loudly in blind euphoria as he was about to cum as well.
"Gnh..gnh..gnh..nghh...don't worry, Mitsuri! I'm not going anywhere!~" He answered briskly with a heavy grunt, keeping the girl's soft and curvy little body held around his waist constantly in a nonstop mating frenzy.
Together their hips slammed back and forth in an ever-continuous exchange of sexual splendor until eventually Mitsuri fell prey to orgasmic bliss and flung her head back with a howl of euphoria escaping her lips! Her legs wound up clutching tightly around Ryuu's pelvis as a result, making him growl like an animal before pumping into her quim one last time before he blows!
"Aaaaaahhhh...! Ryuu!~" She cried out and dug her nails into his skin while feeling his shaft beginning to engorge from inside of her teenage pussy. Ryuu grunted and shoved his entire length into her slot one last time before cumming, he was feeling his balls bloat and pulsate while beginning to cum inside of his little lover's body.
*Splurt...splurt..splurt...splurt...splurt...splurt..splurt!*
Thick ropes of sperm splattered into the girl's pussy, filling up her womb almost instantly while seeing her belly bulge with his cum. Ryuu kept the smaller girl hugging her hips around his dick, squeezing everything she could out of her brother's balls while reveling in the pleasure of having become inseminated once again.
Her body lurched and shook in spasm for just a little while longer before she went ragdoll in his hands falling asleep almost instantly with a blissfully drooling smile on her face. Ryuu sighed in post-sex relief and gently carried his lover down as he lowered himself onto his kneecaps. He laid her on the bed next to their mother, both of whom remained naked with thick ounces of sperm oozing out of their gaping twats.
