Chapter 1
Disclaimer: I do not own MHA or Kim Possible! Obviously.
Ever since he became a teenager, Izuku's life had experienced a massive change. A wild change. A change that, in the eyes of society, would be frowned upon if it were to ever be made public. Yes, Izuku and his sisters are aware of what's at stake, the consequences that'll follow if anyone were to find out about their... unorthodox bond. Not only would it possibly mess up their lives, but also their mother's if they weren't careful. Their mother who's blissfully unaware of what they did behind closed doors.
Despite all that, they couldn't bring themselves to stop. To shove their feelings to the darkest corners of their hearts and revert back to being normal siblings. Well, as normal as adoptive siblings can get. It just wasn't possible. They're too far gone, and they knew that. Yet, they wholeheartedly accepted it.
Fortunately, the walls to their home were soundproof. So, for what young Izuku and his beloved sister Bonnie were about to initiate in his personal bathroom, they didn't have to worry about anyone other than themselves hearing the... fun. As for the risk of getting walked in on, the chain lock and deadbolt on his door took care of that. Hey, a boy in a house full of women needs his privacy, especially when it involves women who are hot as all hell.
Upon entering the bathroom, Izuku bore witness to an astonishing display, his manhood immediately reacting as it begun to swell with life. And who could blame him?
Standing calmly underneath the pouring shower head, Bonnie smiled as she cleansed her flawless face, eyes closed as she brushed her hands gently across her cheeks to rid of Izuku's earlier load of spunk. She sighed in relaxation as the hot water trickled down every inch of her curvaceous figure, pleasant goosebumps poking from her smooth skin as she could feel Izuku's gaze lurking on her backside. Not that she minded, of course. With a smirk, she gave him a little show by wiggling her ass.
"What's wrong, baby brother? Aren't you gonna hop in? The water feels great~" The salacious brunette tempted him further by tracing her fingers down her sides, outlining her insane curves. Afterwards, she proceeded to hug herself, her forearms pressing up on her bouncy double-D's to emphasize their spectacular shape and size.
Izuku trembled in place as he watched Bonnie with plenty arousal, standing merely a foot outside the shower. If he didn't want to enjoy the enticing view a bit longer, he'd be in there right now to satiate his lust, as well as hers. Thankfully, his will's stronger than that. When ready, instead going straight for her, Izuku 'calmly' stepped in.
Like a saucy little minx, Bonnie grinned when sensing Izuku's presence draw closer, shivering with anticipation at what's to come. The buxom brunette would have to wait a tad longer, as much to her surprise, Izuku instead embraced her.
Flushed, Bonnie softly gasped upon feeling Izuku hold her close and with care, the water now cascading on both of them as his arms latched around her waist. He happily nuzzled the back of her neck, his erect cock pressed tightly between her round booty cheeks. While this obviously isn't what she expected, Bonnie smiled as she didn't dare make a fuss, welcoming such tender gestures, too. What's a little gentle before the rough, right? Whenever his warm breath hit her neck, she'd quake with comfort, leaning into him as she lowered her hands to caress his wrists.
Despite what Izuku's... wake-up call may tell, their relationship was more than just them being sex buddies; siblings with benefits, if you will. Their bond... No, their love... ran deeper than that. Much deeper. If it wasn't already apparent, they were together. Like, together-together. If they weren't, they wouldn't even be connected so intimately like they are now, locked in a naked embrace that only worked between genuine lovers. Lovers who could hardly wait to become one at that very moment. For quite some time now, it's how things were between them, and they absolutely adored it, cherished it as they never ever wanted to let go. However, one was just 'a bit' more lucky than the other.
Not only was Izuku in a secret loving relationship with his present sister, but he was also with their two other sisters. More on them later though, as this was Izuku and Bonnie's time.
"You're so beautiful... Bonbon." Said Izuku as he peppered the brunette's neck with pecks, a heavy sigh escaping him as he begun grinding his dick on her ass, starting off slow before gradually raising the pace. God, he just could never get enough of her phenomenal booty.
Pushing said booty against her lover, Bonnie moaned quietly as she moved her own hips with his, biting her lip as she couldn't wait to have him inside her... where he belonged. "Well, duh.. If I wasn't, you wouldn't be so hard, now would you~?" She huffed, her pussy getting more wet by the second. And no, it wasn't the shower.
"Pr-Probably not, no.." Izuku groaned, her thiccc buns gripping his member like a hot smokie while he had them clapping and jiggling.
"That's what I thought~" Bonnie giggled, loving his cock between her phat flesh. However, as good as it was, she wanted more. "So, is this all we're gonna do, or are we gonna... spice things up~?"
"Spice things up, huh..?" Izuku whispered in her ear, the slight rasp in his voice making his sexy sister quiver.
"Mm, Fuck yeah.." Bonnie muttered back, turning her head enough to lock eyes with her beloved brother, her face totally flushed as she gazed deeply into his soul.
"If that's what you want.." Izuku smirked, leaning in to lock lips with the beauty.
Bonnie moaned contently as she accepted his love, raising a hand to hold his head as their tongues did the passion dance. Now more than ever, her pussy craved a good fucking, indicated by her restless grinding as she was desperate to feel his piping hot rod fill her up. If she didn't get it now, she'd fucking burst! Luckily for her, Izuku wouldn't let that happen.
As they kissed, Izuku adjusted himself so that his tip pressed at her womanhood, threatening to breach as he caused her to jolt and squeak ecstatically. Before entering her, he had to mess around at least once, pressing until his cockhead barely slipped in before pulling back.
Bonnie whined impatiently as she ended their makeout session, not appreciating his 'game' as she aimed a cute glare at him. "Oh God, d-don't tease me, please. Fuck, I need it.. My pussy needs your fat cock so bad right now! Please, baby brother... Please fuck me~" She pleaded, panting heavily as she tried forcing his dick into her.
Psht!
"AAAH!" Bonnie suddenly cried as Izuku was swift to put her in her place, making her plump ass ripple as he delivered a punishing slap. However, it wasn't exactly a punishment as the delightful pain had her cumming a little, causing her to groan as her whole form trembled. "Hoooo, fuuuuck.."
"We'll be having none of that now, sis. This time, I'm in control. And I'll fuck you when I'm damn well ready." Izuku chided dominantly, chuckling at how easily the roles can be reversed between them, and how he gets to see a side of Bonnie that no one else can; Just him and him alone.
"Y-Y-Yes, baby brother.. W-Whatever you... say~" The brunette eagerly submitted, a smile of lust stuck on her lips as her heart pounded jubilantly, her face now ever so red as she connected with her submissive self. Her true self. Losing her balance for a moment, she nearly fell forward, but was quickly caught as Izuku grabbed her by the biceps, leaving her leaning slightly.
"Oh, careful now." Smirked Izuku, admiring just how vulnerable his beautiful girlfriend/sister appeared. Now, figuring he toyed with her enough, Izuku opted to end her blissful torment and give her what she wanted; What she needed from him. "Here I come, sis. You ready?" He asked after repositioning himself back at Bonnie's wet slit, already knowing the answer as he powered up his hips.
"Oh, yes, baby~" Bonnie panted heatedly, circling her slippery lower lips over Izuku's pulsing cockhead as she was more than ready. "God, I'm soooo fucking ready! So please, fuck me! Show my pussy who it belongs to, baby brother! Show it no goddamn mercy like you always do!" She cried in utter happiness, her eyes glazed with intense lust.
"Well, alright then." Izuku scoffed, needing no further encouragement as he finally indulged his own temptation. Getting a firm hold on Bonnie's arms, he pushed his cock slowly into his tight sister's cunt, drawing a heavy moan out of them both almost immediately. And he was only two inches in.
Bonnie was once again trembling with pleasure, her eyes crossing as she was finally getting what she deserved. "H-Holy... sh-shiiit!" She exclaimed, grinning as she felt more of her brother's cock invade her defenseless womanhood, her warm wet walls welcoming every inch.
Izuku grunted when making it halfway, taking a quick breather to compose himself. 'Damn... She's as tight as always.' Oh, how he missed being one with his beautiful Bonbon.
"Oh, f-fuck babyyy! I love your cock so much! It fills me up so damn good~" Bonnie squealed like a bitch in heat, losing more of her strength until she was completely at Izuku's mercy. Just as she's meant to be.
"We're just getting started, sis. You..." Holding that thought, Izuku reared his hips... before commencing the final push. "know that!"
Clap!
And with that, he sheathed his whole cock deep within his horny slut of a sister, causing her to arch and scream out joyously as she came the instant he pounded her cervix, nearly busting into her inviting womb. "Th-There we are~" Izuku sighed with satisfaction, holding back from busting his second nut of the day right then and there. Hot damn was it ever close, too. Not wasting anymore time, Izuku then proceeded to fuck Bonnie senselessly, releasing any and all self-control as he made her bounce with every mighty thrust. "This what you wanted, sis? Huh? You want your little brother's cock to make a mess out of your pussy? To make sure that no one else can have it but me! God, what a hopeless and slutty sister you are." He 'scolded' as he gave her bubbly ass another slap, which only added to her pleasure as she moaned even louder.
"Yes, yes, yes, yes! This is what I always want, baby brother~! To have your fat dick ravage me like there's no tomorrow! Like the slut I truly am! I'm yours! My body! My pussy! Every part of me is yours for the taking! So, claim your treasure and fuck me up!" The brunette cheered without hesitation, once again thanking the lord for their soundproof walls.
"Gl-Gladly." Izuku acknowledged as he kept on the assault, forcing himself deeper as he breached into her womb.
'Fuck, yes! I could feel it! His cock is pounding deep into my womb! My cervix never stood a chance! I want it! I want it all! I want to feel him cum deep inside me! I want him to BREED ME! FUCK, PLEASE BREED ME, IZUKU!' Bonnie accepted her fate, getting off even more to the thought of carrying her little brother's child, her womb excited to receive his hot seed for it to happen. For a long time, it's what she wanted, after all.
For a few intense minutes, Izuku held on for as long as he could, unrelenting in their wild love-making as he lost count of the times he made Bonnie cum before he did. But, he does live to please his women.
When it finally came time to hit his own climax, Izuku just had to let go, but not before warning his busty lover. "B-Bonbon! I'm gonna cum!" He announced as his cock swelled and twitched more than usual, grunting as his balls contracted.
"Do it, baby! You can cum inside me! Empty those heavy balls of yours deep in my pussy! You know you want to!" Bonnie happily gave her permission, tightening up so he couldn't escape without a fight. Not that Izuku wanted to..
'Damn it, sis..! Don't blame me... for what may happen next!' "Nn!" After a few final swift and powerful thrusts, Izuku shoved himself deep into Bonnie's core, moaning as he then unloaded a hefty amount of virile seed into his sister's aching womb. Just like she wanted.
As for Bonnie, she experienced an awesome case of Cloud 9 when syncing orgasms with her brother, the chipper brunette squealing with glee while being flooded with cum. And plenty of it.
Splrt! Splrt! Splrt! Splrt!
"Oh, man~" Izuku quivered as he bursted for nearly a minute, Bonnie's vaginal walls ruthlessly clenching to milk him for all he's worth.
"That's it... Th-That's the... st-stuff.." Bonnie gasped as she felt so damn full, her lusty smile still present as her pussy overflowed.
His strength leaving for a moment, Izuku sighed as he released Bonnie's arms, leaving her to catch herself on the wall before slowly collapsing to her knees, her legs spread. She whined the instant her knees hit the floor, as with Izuku's cock having slipped out of her, there was nothing to plug up the copious amount of semen she was rewarded. Like a waterfall, a thick stream of the potent fluid poured out of her gaping hole, the brunette frowning as she watched it all slide down the drain. 'Shit... What a waste..' She complained, now working on recovering her rationality.
Leaning on the opposite wall, Izuku did the same, panting quite heavily as he got over his euphoric high. 'That was... amazing.' Izuku weakly chuckled, pushing himself off the wall once his stength restored. Looking down, he blushed upon seeing his sister's current state, gulping worriedly at her... leaking situation.
Thankfully, he needn't stress. Despite what Bonnie may have thought earlier, she's confident she wouldn't get pregnant as she is on birth control; the whole breeding talk merely her revealing her greatest kink. Now, it doesn't mean she won't have her brother's babies one day. Because truth be told, she will, but even she knew it was too early. Yes, motherhood's always been part of her ultimate life plan, but she's willing to be patient for it.
However, that also doesn't mean it isn't a bummer.
'I wonder if graduation's the time to start trying.' Bonnie pondered with a hopeful smile, rubbing a hand over her toned belly. Soon, she thought. Soon..
Anyway, they should probably finish up their shower and get to breakfast, as they wouldn't wanna be late for school, now would they?
