(Kaito's POV)
"I love you so much." Mai moaned softly as she kissed me, "Don't ever leave me...."
I was sitting down on the couch, having Mai to my right as she kissed me, her hand was on my cock as she stroked. She let out soft and enthusiastic moans as she kept kissing me, not showing any signs of stopping.
Maki was to my left, kissing my neck as she had her hand on my balls, gently fondling them.
"Don't smother him...." Maki said softly
"He's mine..." Mai said as she cupped my cheek, "Mine..."
"Easy..." Maki said firmly, "Don't start now."
Mai eyed my lips, "You're going to be a father, Kaito." she said softly, "A father....Onii-chan....."
I nodded, "Yea...." I said as Maki began to stroke my cock, "I am...."
She kissed my cheek, "You'll be an amazing father, I am sure of it." She said softly, "I know it...."
"Right...." I said as I wrapped my arm around her waist
"My turn..." Maki said softly
She turned my face to her and leaned in, kissing me on the lips as Mai leaned down and kissed my chest. I felt the way Maki's tongue wrapped around mine passionately as Mai kept kissing me all over my exposed chest.
Arousal and bliss spread throughout my body as the two of them did this. I could feel how both of their hands were stroking my erect cock while I sat there, letting it happen.
"Hmm~" Maki let out a moan as she pulled away, "You're such a good kisser."
I licked my lips slowly, "You could say I had lots of practice." I said, "I mean, with Naoya-"
"I know." She patted my cheek, "You don't have to remind me."
She leaned closer, kissing my cheek as Mai kept kissing my chest and neck. It all felt so good, I really didn't know how to explain it. The two of them were there in my arms, kissing me while stroking my cock.
It was like a dream, truth be told.
My two beautiful sisters, doing this with me. I knew that this was taboo and immoral, but it felt good. And I knew that my beautiful and beloved wife wouldn't mind this; I knew that Naoya would encourage it. She's the reason why this had started, that wife of mine.
"I love you." Maki whispered, "I don't care about anything or anyone else, Kaito. I want to be with you. I don't give a shit if you're married to Naoya, I want to be yours. Only yours."
Mai leaned closer to my ear, "Same here." She said, "Naoya wants us to be yours too."
"I know." I said, "I know, girls."
"Fuck what the Clan or anyone else says." Mai said, "Marry us too, Kaito."
"What?" I said, "Mai, that's-"
"Shut up." Mai said, clutching my chin, "You married your cousin, so marry us too."
"Polygamy is outlawed." I said, "That's-"
"Do you think the laws are stopping you from doing anything else in this Jujutsu World?" Mai asked, "To hell with the laws and to hell with the Jujutsu World. All that matters is that we love each other, Kaito. I fucking love you, don't reject me....."
"Mai...." I said as she looked at me with tears, "What you're asking is...."
"Enough." Maki said as she kissed my cheek, "Let's talk about that at a later time."
Maki then straightened up, taking off her panties while still wearing her tank top. She straddled me and gently inserted the tip of my cock inside her pussy.
"Ohh~" She let out
"No fair, Maki~" Mai pouted, "I wanted to be first."
"Gotta be quicker, then." Maki said as she slowly lowered her hips all the way down, her pussy taking all of my cock inside, "Hmmm~"
She gripped my shoulders as I had my arm around Mai, pulling her closer. Maki looked at me with her intense gaze, which was quite arousing.
"Your cock is as big and hard as ever, Nii-san...." Maki said softly
I felt the way her pussy was wrapping around nice and tightly around my cock. Maki held her position, her body trembling slightly with pleasure as she looked at me.
"Kaito..." Mai said as she kissed my neck, "Love us.....love us till the end...."
"I do love you." I said as Maki began to move slowly, "I always loved you."
Maki leaned in and kissed me on the lips, my free arm wrapping around her waist. I felt as she moved her hips up and down slowly, my cock was rubbing against her insides with every single movement.
"Hmm~" Maki moaned through our kissing, the feeling of her pussy tightening on me was amazing, "Mmm~"
We kept kissing as she rode me, her body pressing against me as she did so. My hand ran down to her ass, squeezing one of her cheeks as she did this. Her pussy clamped down tightly after I did this; she was clearly aroused by this.
This caused her movements to get a bit faster, her hips moving up and down as the sound of her riding was a bit louder.
"Plapplapplapplapplapplap"
Maki pulled away, "Ahhh~" She let out, "Nii-san....you're so good...."
"You're the one doing the moving." I said with a chuckle, "You're the one who's doing good, Maki...."
Maki blushed deeply, "This is how much I care for you." She said, her pussy clenching down hard on my cock, "Kaito...."
She took her shirt off, revealing her beautiful and bare body. I reached for her breast, gently squeezing it. This caused her pussy to clench down even harder as she rode me, making the feeling get even better.
She slowed her movements down, her hips going in a circular motion, causing my cock to grind against her insides.
"Ohhh~" She moaned, "Kaito...."
"Such a beautiful sight~" Mai said as she kissed my cheek, "Our sexy sister riding you~"
Maki grabbed my wrist as I groped her breast, "D-Don't stop, Kaito~" She let out, "Don't stop this~ Ahhh~ I want this to last forever~"
"Fuck me good, Nii-san~~"
