“Fufufufufu~,” Kuroka giggled, watching her precious Issei sleep. For the longest time ever since she became one of his fiancés, she has been constantly trying to bed him and produces strong children with him, but he refused to do so saying that he wasn’t ready for kids yet. Well, Kuroka was getting impatient. She wanted Issei’s children, and she was going to get them no matter what~. Luckily for her, no one else was home and she had a plan to get what she wanted.

“My dear Issei you worry far too much, nya~,” Kuroka said, slowly running her finger across his bare chest. “All I need from you is the seed, the parenting can be done by yours truly~,” she said activating her senjustsu. If Issei was going to willingly give her what she wanted then she would have no other choice but to manipulate his life energy and make him more lustful, make him desire her body so much that he would be more open to having sex with her.

“Nnnnnh~. Kuroka is that you?” Issei asked, slowly waking up to see that she was sitting on top of him. His body was getting warmer and his lower member was getting aroused.

“Shh~. Just relax, nya~,” Kuroka said, seeing Issei’s face start to become red.

“Kuroka what are you doing!?” Issei asked, trying to push her off of his body, but it was no use, for some reason his body felt weaker than usual.

“I’m helping you to relax my dear, nya~. Doesn’t it feel good~?” she asked, feeling him slip further and further into her grasp. Today was the day. Today was the day that she acquired what was hers~!

“It… it does~,” Issei said almost completely under her spell. However, despite her efforts trying to tame and control someone that has draconic energy which has a Longinus containing one of the two heavenly dragons was not so easy.

“Issei, you fucking idiot! She’s trying to steal your seed!” Ddraig yelled from Issei’s Boosted Gear. “You have to snap out of it!”

“But her skin is so smooth, and her tails are very soft~,” Issei said, stroking Kuroka’s tail much to her pleasure.

“Give it up you foolish dragon, nya~,” Kuroka said mocking Ddraig. “Issei is a true man unlike you~. He knows what he wants and always has~. Just look at his-nnnh~, hands they can’t resist my wonderful breasts~.”

“You fowl temptress!” Ddraig yelled at her. “I refuse to let you take control of my host like this! Begone thot!” Ddraig yelled, using an old tired meme thanks to his mental connection to Issei.

“Ngghhhh!!” Kuroka grunted as Ddraig's draconic energy started to collide and push back her life force energy. “I won’t let you win!” she yelled shoving her tongue straight down Issei’s throat to help channel her life force energy.

“Nghhhhh~!!!!!” Issei moaned out as a wave of ecstasy began to wash over his body. Currently, both Kuroka and Ddraig were fighting to take control of his body, and the constant collision between her life force energy and his draconic energy was causing Issei’s body to change!

“Nnnnn~! Mmmmm~! Nnnnnn~!” The more that Kuroka twisted her tongue around his tongue and throat the stronger her life force energy become. In a matter of seconds, his hair slowly began to turn the same shade of black as her own and slowly began to grow out.

“H-how!? How is this possible!!” Ddraig yelled, feeling his draconic energy begin to diminish as Issei’s lips began to swell and his face began to become more feminine.

“This shouldn’t be possible!” Ddraig yelled realizing that Kuroka was far stronger than him. He did not expect her to be this strong and by the time he had, it was too late to stop her. Not to mention that Issei had already lost his right to wield Ddraig since his body was no longer a demon nor was it a human, it became just like Kuroka’s.

“Nnnnnnnnnnn~!!!!!” Issei moaned out in pleasure as she ran both of her hand up his side giving him a curvy waist just like hers before she began to grope his sturdy chest.

“P-please… stop this!” Ddraig yelled, begging Kuroka to stop Issei’s transformation, knowing that the further it progressed the weaker their connection would become. He was struggling just to keep himself conscious at this point. Though his pleas were worthless. Kuroka knew what she wanted and seeing that Issei was transforming into her there was no way in hell that she would stop~! No one or thing could stop her from making them one~!

“Mmmmmm~!!!” Issei moaned again as breasts began to form on his chest. With each grope that he received from Kuroka, his breasts became bigger, and bigger, until they were the exact same size as Kuroka’s. His shirt started to tear at the mere size of his new breasts, and Kuroka giggled to herself when she saw that.

SNAP!

With a snap of her fingers, she transformed his clothes into the same sexy black kimono that she was wearing. And even though she wasn’t fully transformed, she could tell that it suited her soon-to-be twin~.

“Nghh~” Kuroka grunted, feeling her life force energy being overpowered by Ddraig. Though she could feel it~. She could feel Ddraig becoming weaker as her influence on Issei’s body and soon-to-be mind was increasing. Issei was starting to subconsciously reject Ddraig’s help! All that was needed was one final push~.

“Ahhhh~!!!” Issei let out another moan as Kuroka began to massage his ass. With each motion, his hips, ass, and thighs became bigger and bigger. Soon his manhood even shrank until there was nothing left, welcoming her to the wonders of womanhood.

“Stop… you… you have to… stop,” Ddraig said as a cute pair of black cat ears and twin cat tails appeared on Issei’s body. Ddraig was now powerless to stop Kuroka’s personality and habits from affecting Issei’s mind. His powers were becoming sealed once again and would become dormant forever.

“Oh my~. Now are you perfect, nya~,” Kuroka said embracing her new twin. Her kimono looked great on her as did her tails and ears~ “So how do you feel~?”

“I feel wonderful, nya~,” Issei said back to her. She didn’t understand why she felt better in this body than she did in her old one. Though she knew for certain that she loved having a voluptuous body like this~.

“That’s good nya~,” Kuroka said back to her. “Now, I do believe that we have some fun taking care of nya~,” she said before they became to make out starting a night that neither of them would ever forget~.

-2 Days Later-

“Onee-chan, Issei-san, I home nya~,” Koneko said walking inside. Though to her dismay, the entire house was a mess. Her big sister was by definition a lazy slob. All she did was play video games and eat their food while trying to flirt with Issei.

“Oh Koneko-chan, come over here, nya~,” Kuroka said, revealing that she was sleeping on the couch again with the tv turned on, wearing her skimpy black kimono which barely covered her breasts as she always did. It looked like she went through another one of her game binges.

“What is it onee-…chan’s?” Koneko said shocked to see that there were two of her big sisters sitting together, wearing the exact same outfit. It was impossible to tell them apart, even their smell was the same! “Onne-chan what is this, nya?”

“Koneko you’re being rude to Issei-chan, nya~,” Kuroka said revealing the truth to Koneko without hesitation. “Don’t worry Issei-chan you look lovely in my kimono, nya~. So much better than how you dressed before, nya~.”

“Oh don’t worry Kuroka-chan, nya~,” Issei-chan said back to her. “Koneko is just jealous to see that my body is far more developed than hers, nya~,” she said teasing the poor flat-chested Koneko.

“Fufufufufu~. My dear twin how right you are, nya~,” Kuroka said back to her. “Don’t worry Koneko, one day I’m sure that you’ll have a voluptuous body kike ours, nya~.”

“N-no…no way,” Koneko said, stunned by what she was just witnessing. This had to be a bad dream, not a nightmare! She had to wake up! She just had to!

“Now, now, Koneko-chan be nice, nya~,” Kuroka said, teasing Koneko for being tense around Issei-chan. Though after tonight she will realize that Issei-chan’s new form is for the best.  “Issei-chan is also your big sister now, so you best get along, nya~.”

“Come Koneko-chan, we’re about to start a new game and need a third player, nya~!” Issei-chan said, grabbing Koneko and sitting her in her lap right next to her fat breasts, much to Koneko’s embarrassment. Oh, this was going to be a fun day~.
