Shuichi has a lot of respect for kaito he really does, but he just could help stealing Maki away from him. Everything about her was such a turn-on. So when he walked in on her naked, he did the only sensible thing to in that situation he claimed and not made sure that'd shed be crying out his name for the foreseeable future
"... Hm? Ah, Kaito. Could you help me get dressed? You know it's hard for me to pull these up, so..."
Shuichi was... Honestly shocked he'd ever get to see Maki like this. The boy having gone to fetch Maki for the usual training session; He'd ended up walking straight into her room without her realizing it was him... And to top it off, she was bare-ass-naked in front of him! He... He really, really shouldn't do this. He tried his damnedest to steel his resolve and ensure he wasn't about to ruin his friend's girlfriend for life, but...
He'd already found himself walking up behind Maki, his hand finding its way to grip a handful of the assassin's doughy, wobbly beta-killer asscheeks... Prompting a wide eyed expression from Maki for a moment! But, considering who she still thought this was; She calmed herself, simply groaning and shutting her eyes in response.
"Do you-- Ugh... You're really that needy, huh?... Fine. You won't take that long anyway, so-- Just hump away for now, and I'll get myself cleaned up before Shuichi needs us."
... At least, she -assumed-this was Kaito before she felt something undeniably meaty immediately thwacking onto her rippling, wobblebait ass... Even if he wore a toy, Kaito never gave off this heat, either. This was... Th-This was...
"Wh- Who the fuck is thi--"
----------------------------
"OOOOOOOONNNGHHHHHHH!~~~ SHUISHIIIII!~~~ GOOOOOOOD-- PLEEEEEASE, DON'T FUCKING STOOOOOP!~ I NEEDED THIS SO MUUUUCH- MOREMOREMOREMOREMOREEEEE!!!"
PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP-!!!
... Now, Shuichi was certain he wasn't entirely ruining his friendship with Kaito... After all! Even if it was under the wrong assumption, Maki was the one letting him do this... And she did seem pretty disappointed with Kaito's abilities to please her. He was just doing him a favour by railing Maki until she goes braindead-- Having her cheeks wobble and crash against his pelvis, rippling with every thrust was just what he'd want him to do! Though, hopefully Maki's bed doesn't break under this...
"Uh.... Yo, Maki-Roll? You're, uh, late to our workout. You alright in there? I haven't been able to find my sidekick all day, either! You see him, tell me what's up, okay?"
Unfortunately for Kaito... Through the door was a Maki laying face down on her bed-- Legs twitching, gut completely bloated with Shuichi's seed, ass straight up in the air as gallons of spunk oozed out of her holes. Poor girl had her face nose first in her own pillow, eyes having rolled into her head and drool completely coating the pillow in question. Unfortunately, she was in no state to answer Kaito like this-- Not for a while. While it seemed Kaito was about to come in and see the ruined assassin...~
"Ah-- She's, uh, she's busy, Kaito! I'm just helping her with something right now! Come back in, uh.... Come back tomorrow and we should be ready, alright?~"
With a barely audible groan from Maki...? NΓ³ doubt they'd be going at this for a long, long while.~
