With every month that passed, izuku found that his restraints were being tested. If not, then why would his precious iku look more and more enticing? It was no longer enough to just have her suck his cock or cover the entrance of her tiny pussy with his cum. It was not enough to rub the head of his erection between her legs, none of it was enough anymore.
With each and every day she grew more radiant. The prettiest 5-year-old he’d ever set eyes on.
With the pay increase that comes with hero work, izuku had managed to move his beautiful family into a much nicer and larger house with enough rooms for all their fun little activities. And of course, he’d christened every room with his beautiful mother. Spreading inko out onto every available surface.
But daily activities were now proving challenging with his need for iku growing. Not to mention, she was at that age where all the silly little neighbourhood boys would tug on her pigtails as some strange show of affection. Really he couldn't be blamed for his sudden need to stake a claim on his little girl.
He looked up at her shuffling about the house. She enjoyed the larger space. More places to hide during hide and seek she’d said. Today she had dawned a white dress with ribbons at the shoulders. Her forest green curls propped up into two pigtails as usual and the mental image of grabbing her from behind with her pigtails and bouncing her on his cock filled his mind. Really it was probably some of the more tame fantasies his perverse mind had come up with all week.
He stared at her plump and chubby cheeks with a myriad of light brown freckles dotted around her face. Sticking out of her mouth was a blue baby pacifier. A habit she picked during the moving producers after they unearthed her toys and whatnot from when she was younger. They hadn't seen a reason to stop her so they let it be. She never had it in for longer than an hour a day and it was just something to occupy her.
Really his little girl was too much to handle. Whenever he got off work early and manages to be around for bath time it always ends with iku’s little hands wrapped around his girth till hes shooting white ribbons to the surface of the water and catching his breath. Even worse when she rushes in to take showers with him because “you'll be away all day” and less than a minute into the shower and he has the little 5-year-old lifted and pinned against the wall at the perfect height to tease the head of his penis on the folds of her little hole.
Each time getting closer to fucking her silly.
But the more he thinks about it, why shouldn't he enjoy the fruits of his seed? Iku was born of the love he holds for his mother, she is his everything. Daughter, and sister all in one. So why not his lover as well? Besides his little girl will not be little forever. He should be her first and last but most importantly she will not remain so small and doll-like. He should enjoy and love her at every stage in life. It's only reasonable.
So that settles it then, he watched her play for the rest of the day merely planning before excitedly telling iku about how he was ready to share even more love with her as he tucked her into bed. And like a good little sister she was just as, if not more excited.
He thought of how small and tight she would be. How warm, wet and inviting her pussy would feel. He let his hands travel beneath her blanket and into her pyjama shorts gently rubbing her tiny clit. Watched her release a sigh and gently hump his hand until she slept. He thought of her cum filled cunt even as he was balls-deep in inko later that night pumping her full of everything he could. And even as they cuddled, his flaccid dick still in her cum and piss-soaked hole he thought of his perfect sleeping little doll.
He told inko about how he was so desperate to show iku how much love her father wanted to give her and although hesitant his mother eventually went along. She too must have thought of how wonderful and special their family was and this was just the next stage.

Izuku made his way home from the early evening patrol, he’d switch with someone else to get the earlier shift. He took out the small zip lock bag that housed six small pills the size of rice grains. The perfect dose for his little iku. He’d swiped them from the numerous things locked in the evidence lockers. Completely non-toxic. The pills were made with less than savoury plans for them but that was why they were clearly better in his care than anywhere else.
Once he reached his home. Izuku was quick to crush one of the pills into a pot of iku’s favourite yoghurt, mixing thoroughly.
“Iku sweetie” he called out to her from the living room. She was dressed in the prettiest blue princess dress, sleeveless and gave her a very cupcake like appearance. Matching blue ribbons in her pigtails and a yellow pacifier in her mouth, a new one perhaps.
She practically skipped, clearly excited for today.
She pulled the pacifier out and accepted her pot of yoghurt and ate it without a second thought, licking the spoon clean once she was done.
“Your special medicine will only take a few minutes ok?” he walked her back into the living room. Pushed the furniture further apart to give them even more room on the tiled floor. Her large green eyes were already blown out and her lids were half closed.
Her body slumped against the leather seats, limbs looking heavy and useless as they lay by her sides.
“So perfect for me my little iku”
He tugged her towards himself and she fell much like a puppet that had its strings cut. The complete relaxation of her muscles. She was still very much conscious but was unbothered by the happenings of her surroundings. A living doll.
The strain in his pants grew.
He laid her onto the floor, lifting the skirt of her dress enough to see just how much the drug had set in and was not disappointed. Wetness leaked out of her. Covering her inner thighs in a shine. He rubbed two fingers between her folds. Just those two fingers were enough to cover her whole pussy.
He rubbed and pushed open her entrance absolutely smitten with the sight of a small, tight cavern waiting to be stuffed full and bursting. He looked up at her pear-shaped body, with her chubby arms and legs, her cherub-like face and that pacifier still stuck between her lips.
He pulled it out rubbing the soft rubbery end between her legs, up and down her slit. He pushed the head of the pacifier into her wet hole. As far as it would go, leaving the yellow stopper sticking out cutely. Absolutely adorable, he thought. He snapped a picture of her. Close up. It was too cute not to. Perhaps he would get her a photo album to house memories of this new chapter of their relationship. He had files and videos backed up but something more tangible seems fitting for his little angel.
He twisted the pacifier in her hole, pulled it out and pushed it back in. fucking her sopping wet cunt with it, over and over. Increasing the speed and watching more liquid leach out of his perfect little iku.
“You so ready my little doll” he choked out. He’d never been so aroused in his life.
Pulling the pacifier out, he was quick to place it back into her mouth, positioning himself and pulling his hard, veiny cock out from its confines. Went ahead and stripped himself completely. He squeezed a generous amount of lube onto his palm, using it to stroke his arousal till he was fully coated and twitching.
Once izuku was ready, the hero pushed into his 5-year-old daughter. He felt the stretch of relaxed muscles swallowing him inch by inch. He stayed still to feel just how tight her virgin cunt really was.
The young man pushed further and further, his groans of pleasure echoing in the large house. He rolled iku’s dress up further where he could see a lump on her stomach where the head of his cock was nestled and it drove him mad. Izuku thrust his hips pushing himself all the way into his sister's warm and welcoming entrance. He felt his eyes roll to the back of his skull, the pleasure unbearable. Unlike anything, he’d felt.
The imprint of his penis he could see through her stomach moved with every thrust, her limp body bounced and shook with each movement, the prettiest living doll in all existence.
Izuku could feel trails of his own drool sliding down his chin and jaw with how gone he was. The sound of sticky skin slapping against each other in the most erotic of ways. He watched her vacant eyes blink up at him. With how relaxed iku’s body was it was no wonder he soon felt a hot stream of piss flow out of her onto his dick adding to the filthy sounds already in the room.
That was also the tipping point as izuku sped up and shot his spunk into his sister's most intimate parts. Watching all the fluids churn and froth with each continued thrust.
He pulled his glistening cock out. Still as hard as it was in the beginning, but with how much he wanted this, it hadn't even surprised him. Cum flowed out of iku’s spent hole pooling on the floor between her legs.
He stripped the little girl completely, grabbed a pillow from one of the pushed-back couches and positioned her. With her weight rested on her knees, legs spread, ass up and cum filled snatch on show.
He knelt behind his little angel, reaching for her pigtails, one in each and, pulled her up gently till she was arched like a trained whore. He pulled her back onto his flush cock, rocking her back and forth, feeling the skin of his cock drag with each thrust, hearing the unmistakable sounds of sex. The slap of skin on skin continued and izuku was sure he was drooling once more. The corners of his eyes pricked with warmth. He had truly never felt so good.
When he came again, it was long, intense and seemingly never-ending. He choked on his own pleasure and pumped the 5-year-old full to the seams and further relaxed when he began urinating in her.
He set her down onto the pillow gently, leaving her hips pushed up as he emptied his bladder and the warm piss splashed out of her. When he pulled his cock out more piss and cum ran down her legs to the floor leaving her shiny, chubby, pink pussy on display.
He lifted the naked child into his arms with her back against his chest as he lay on a dry part of the tilled floor. Almost two hours had gone by, meaning he most likely had about twenty or so minutes left before the drug fully wore off. He also finally took notice of the figure in the doorway.
Inko stood watching. He wasn't sure how long his mother had been there but with her here now, he sat up. Back leaned up against one of the leather seats, iku still laying on him. He held her legs open and gestured for his mother to join them.
Inko made her way, dropping to her hands and knees with her head between iku’s legs. Licking the small and most likely sore hole. She sat up, rolling her skirt up till she could comfortably rub her juicy folds against her daughters. With how they were positioned izuku pushed his quickly stiffening rod between the two wet pussies of his mother and sister, fucking the space between them. Feeling wet skin sandwiching his cock. Feeling the rub of their folds stroke him to his final load.
He could feel himself shake with the intensity and his strength collapsed.
This was a day he wouldn't soon forget.
Iku was finally, truly with them.
