In Naruto as Ten Tail

Seeing Tsukimi appear out of nowhere Matatabi jumped at him to hug him but she suddenly felt the direction she was going change.
*Boom*
After she was smashed into the wall, she got up only to see Kokuo hugging Tsukimi while nestling her head in his chest. From the corner of her eyes Kokuo seemed to be smirking at her.
She seemed to be declaring her victory and ignored her soon only to start sniffing Tsukimi from head to toe.
Amused by her reaction, Tsukimi did not even interrupt them because he knew better than to think they were fighting. He had seen them grow up from the time of their birth, so he could tell when they were serious or not.
Matatabi got up and walked towards them with a dark expression but when she got closer to them she was pulled by Tsukimi in his embrace and he smacked his lips against her, shutting her up.
There seemed to be slight annoyance in her eyes which gradually disappeared when Tsukimi pried her mouth open with his tongue and continued attacking.
Kokuo sniffed his chest and kept going lower and lower until she reached the area where there was a slight bulge in Tsukimi's pants.
She used her hands to rub the bulge above the pants and sniffed it a little too.
Tsukimi used his hand to pat the little beast which seemed to make her actions even more aggressive.
She unzipped his pants and released the beast from its cage. Kokuo's eyes were replaced by heart shaped eyes seeing the semi erect dragon in front of her eyes.
She took a deep breath to inhale the manly scent of her husband before giving a small peck on the tip of it.
While she was kissing Tsukimi's dick she even used her tongue to peel his foreskin backwards while tracing it around the head of the shaft.
Her hand made their way to hold the shaft and pull the skin backwards, Tsukimi stopped patting her head and started stroking it instead.
He did not forget Matatabi as he started moving other hand to grope her ass from one side and knead and stretch it.
Matatabi also reply using her hands to remove his robes and move her fingers on his solid body.
Tsukimi got more aroused as they continued their act. He did not forget to place a time seal in the room to slow the time inside the seal.
Kokuo was now excited to see Tsukimi fully erect while half of his member was inside her mouth.
She was happy that Tsukimi was feeling good and increased the pace of her sucking, with each movement she took his dick deeper and deeper in her mouth until it hit the back of her head.
Her eyes were rolling backwards as Tsukimi could feel a weird sensation all over his lower body.
After adjusting to the size Kokuo took in his penis even further inside her mouth until it was fully inside of her.
Tsukimi did not stop her as he was feeling very good doing this for the first time. Even though they had never done this before the muscles of a tailed beast are very flexible.
Kokuo started bobbing her head up and down while her own insides tingle from the excitement she was feeling at the moment.
Matatabi, seeing the blissful expression of her sister Separated from Tsukimi and broke the kiss.
She kneeled down beside her and started sucking on his two balls one by one. Tsukimi placed both of his hands on the heads of the girls and closed his eyes and enjoyed the moment.
Matatabi pulled Kokuo back by the neck and took his whole cock inside her throat In a single movement. she looked at her with a similar expression. Kokuo looked at her when she attacked her.

Matatabi also wrapped her tongue around his dick while sucking on it at the same time.
Tsukimi's dick twitched feeling good from many side Kokuo did not waste time on Matatabi and took her place in sucking other parts.
Before Long Tsukimi reached the peak of pleasure and his lower body started twitching and he released a huge amount of load inside Matatabi's mouth.
Seeing her gulp down the semen like a greedy cat kokuo pulled the dick out of her mouth and attached it to her mouth but her actions caused Tsukimi's cum to spread all over their faces and bodies, drowning them in a small shower of cream.
Kokuo did not mind and enjoyed it by greedily taking in what was coming direct from the source.
Matatabi got angry and instead of doing anything to the girl she picked her up in her arms, surprising her.
*Yelp*
Tsukimi was getting a little annoyed seeing them play while he was in the middle of releasing.
Matatabi seemed to sense his dissatisfaction and looked at him apologetically while spreading Kokuo's legs in her arms and saying.
"Here dear it's all ready for you."
Kokuo's face flushed red seeing the position she was in and she covered her face to hide it from Tsukimi. Matatabi seeing this reaction smirked in victory while Tsukimi was further aroused seeing Kokuo's gaping pussy as if screaming for him to enter inside of her.
His dick which deflated a little because of getting annoyed was now even more harder than before and even longer as it twitched.
Tsukimi walked closer towards them and used his thumbs to spread the little pink hole to maximum.
Kokuo looked at his cock which knocked at her entrance from the gaps of her finger and her inside trembled. Then Tsukimi's husky voice came, sending shivers down her spine.
"~I am going in~"
