[A/N: Will try to get back to 10 chapters on the other side (link in bio). In the meantime, enjoy]
(Kaito's POV)
"A-Ahh~" Maki let out a moan as I was kissing her abs, my fingers on her pussy, "K-Kaito~"
I kept kissing her toned abs, feeling how her pussy was overflowing with its juices. The way her body was trembling to my touch was simply adorable, I couldn't help but form a slight smile as I saw her.
I kissed her abs, working up to her chest, "Hm..." I said, "Such a pretty sight."
Maki was blushing, "W-What?" She said, "Shut up, idiot...."
I gently inserted my fingers into her pussy, feeling it clench hard in response. Her body convulsed as I began to finger her, feeling her arms grip my shoulder as I did so. I then ran my tongue up to her chest, feeling as she shuddered to this.
"Naoya likes it when I do this." I said softly, feeling how her body was trembling in pleasure, "Mai hasn't received this treatment yet, but she has taken a good amount of my pounding."
Maki was blushing deeply, "Ohh~" She let out, "Y-Your fingers.....ahh~"
I noticed that Mai and Naoya were sitting on the couch, watching me finger Mai.
Mai had her hand on her mouth, "Oh my..." She said, "That looks so good."
"Fufu~" Naoya smirked, "It feels amazing. I'll have him do that to you after he's done with Maki-chan."
Maki was breathing hard, looking at me as I fingered her, "O-Oh...." She said, "D-Do it again.....t-the licking...."
I nodded, "Very well."
I leaned down and kissed her abs, feeling how she trembled to that. I then licked them a bit, proceeding to run my tongue up her abs and towards her chest. Without warning, I licked her breasts, flicking my tongue against her nipple.
Her pussy clenched hard onto my fingers, "Ahh~" She moaned loudly, "Kaito~"
I took her nipple into my mouth, sucking on it gently as I fingered her a bit faster. Her body was trembling in pleasure, her moans were getting louder as her back arched slightly.
"Hnnngh~" She let out a moan, "Ohh~"
"No fair...." I heard Mai say, "He didn't do that with me."
"Easy, Mai-chan~" Naoya chuckled, "You'll have plenty of time with him from now on. He'll show you a real good time."
Maki wrapped her arm around my neck, "K-Kaito~!" She let out, "Hmmm~!!"
I pulled away, licking my lips, "I'm getting carried away." I said, clearing my throat, "Ahem. Sorry...."
She looked at me, panting slightly, "It's fine...." She said as my fingering stopped, "That was....I wasn't prepared for that."
I caressed her cheek with my free hand, "It makes me happy that you no longer see me with that cold and hateful stare, Maki." I said, "The two of you, that is. You've made your brother happy."
She frowned, "I already said I was sorry."
"It's okay." I leaned in, kissing her lips briefly, "It is okay, my sweet Maki."
She blushed even more, "Kaito..."
"He's kissing her even more?" I looked over to see Mai biting on a pillow, clutching it tightly, "I'm so jealous.....!"
"Easy, girl." Naoya was leaning back casually, "Let's enjoy the show. Kaito will be more than able to handle the two of us after Maki-chan. He once ran a gauntlet with at least six women in one night before he humbled me, having me trembling hard after he filled both of my holes. After he was done, I was licking and kissing his feet and foaming at the mout-"
"Naoya." I cleared my throat, "Enough."
Naoya blushed, "Teehee~"
Mai pouted, "I want more kisses, Onii-chan...."
"Just wait, okay?" I said, "Let Maki get some attention."
"Kaito...." Maki patted my cheek, "M-More....kisses..."
I looked at her, "Right.." I said, holding her by the waist, "Right away."
I leaned down and kissed her briefly, feeling how she leaned up to my kisses. I ran my hand down her back and to her ass, gently squeezing it.
"And he's feeling her up...." Mai said, "Ohhh, that's not fair...."
"Haha~" Naoya said, "This is amazing~"
I kissed Maki again, feeling how she pressed herself against me, "Maki..." I said, "Do you want to make Mai jealous?"
She nodded, "Maybe..."
I cupped her cheek, "Hm...." I said, "I don't want the two of you fighting over me, alright?"
She looked at my lips, biting her own slightly, "I just...." She said, "I just enjoy your lips..."
"I see." I said, "You and Naoya are alike in that manner."
"I love your cock too, don't forget~" Naoya said with a chuckle
"Speaking of...." Maki said with a gulp, "C-Can I?"
I nodded and sat down, "Yea." I said, "Get on your knees."
"Oh, assertive~" Naoya said, "The fun begins now~"
Maki got on her knees and positioned herself between my legs, "Right....." She said, "I....well...."
I pulled my cock out, which was already erect, and Maki widened her eyes slightly.
"There..." I said, "If you want, we can take this slow."
She grabbed it gently and leaned down, opening her mouth and taking it inside. I felt the way her tongue gently wrapped around the shaft and she began to suck on it.
"Whoa..." I said, "M-Maki...."
She bobbed her head up and down, looking at me with her lustful eyes, "Hmm~" She hummed, "Mmm~"
The way she sucked me off felt quite nice, making me think she was already experience in this.
"Maki..." I said, "Have you done this before?"
She pulled away, "N-Not with a real one..." She said, licking her lips, "I.....well..."
I raised an eyebrow, "What?"
She blushed with embarrassment, "I have practice with a dildo...." She said, "Occasionally fantasizing about you, pretending it was your cock."
"Oh." I said
"Naughtyyy~" Naoya said, "I love it~!"
"Yea, that's crazy." Mai said with a chuckle
Maki closed her eyes and composed herself, "Tch...." She said, "No matter..."
She leaned down and opened her eyes, licking the shaft as she gently stroked the top of it. She rubbed the tip with her tongue, her nail gently scratching the slit. This sent a jolt of arousal throughout my body, it felt quite good.
"Whoa...." I said, "That's...."
She was blushing, "I want to make you feel good, Nii-san...." She said, a determined yet adorable look on her face, "Please, don't ever refuse me. I love you, I really do."
"Accept my love, Kaito..."
