I'll admit I had a bit of trouble writing this one rocketplayz_dr. While you gave me the description of your OC in terms of appearances, you gave me no personality to go with. As such, I just had to make it up on the spot. Regardless, I hope you'll enjoy.

Keebo was always cautious when heading to the mastermind's lair. Given his robot body it'd be weird to go inside a bathroom; the ladies' bathroom no less. It helps to keep suspicion off of him if it's found, but he supposes the cons and pros balance each other out.
He would head there whenever he could. It wasn't easy, considering he had Miu and Kokichi constantly trying to bug him. Speaking of which, he should probably set up the next murder to include one of those two; maybe both? Who knows.
Inside the lair, he had Mother Monokuma pull up camera footage for the school. Specifically, he was trying to find one individual in particular. Sage Greenwoods was the one who had caught his attention. His heterochromia of magenta and orange eyes certainly gave him some individuality. He wasn't the loudest one of the group, but perhaps that's simply because this group of ultimates have so many loudmouths that just won't shut up.
It wasn't long before Mother Monokuma pulled up images from multiple cameras showcasing the person of interest. Sage was in his dorm room, the door locked. Sage was on his bed, his attire quite different from normal, as in he wasn't wearing anything. Sage had his back resting against the wall near the back of the bed, back partially off the wall in an arched position. With one hand he held his dick, rubbing up and down to give it stimulation. He'd occasionally mess with the tip of it, his arch increasing whenever he did so. His other hand cupped his mouth, the sounds that would be echoing off the walls muffled so that only a quiet whimper escaped.
The sight was something Keebo could've only hoped to see, the soft sounds picking up perfectly on the cameras. If Keebo currently had a dick, he surely would've been touching alongside Sage. The view was simply breathtaking, as if time had slowed down.
Still, Keebo wanted more. He didn't just want to watch, he wanted to touch. He wanted to feel the frame of Sage, bring him pleasure only he could bring. He debated upgrading his body himself, but knew that there was someone among the group that would be able to know what was hot and come up with ideas he simply wouldn't think of.
Regrettably, he left the mastermind's lair as he set out to find Miu. He figured Miu would tease him, and probably ask who was the lucky person, but he was willing to endure it.
Despite the teasing, Miu was willing to give him plenty of upgrades. Keebo was relieved to not have to resort to violence or threats, and it wasn't long before he was off towards Sage's dorm room where he still remained. Being a robot, he can receive answers from Mother about the camera's footage; it's just easier when he can see it in person... uh, robot.
Keebo hesitated ever so slightly in front of Sage's dorm, nervous about the encounter. He knew he was everything Sage could want and more, but he needed Sage to believe that for this to work. Building up his courage, Keebo knocked on the door.
He could hear Sage scrambling around to get to the door, able to imagine the panic as Sage tossed on the clothes that had been scattered around the floor. Soon enough though, Sage answered the door.
"Hey... Keebo. Can I help you?"
Keebo nodded, excitement building up inside him.
"Yes. I couldn't help but notice some... strange sounds coming from your room. I just wanted to see if you were alright."
Keebo witnessed as Sage's face turned a bright red, avoiding eye contact due to embarrassment. Of course Keebo knew what those sounds meant, but he wanted Sage to admit to it himself.
"Y-Yeah, I'm just fine... I was just... you know... I mean, you wouldn't get it... I just..."
While it was cute to see Sage fumble with his words, Keebo wanted to get straight to the point.
"Oh, wait... Those sounds are similar to what Miu said people sound like when they're pleasuring themselves. I'm sorry for interrupting you."
Sage rose his hands as if putting a defense up, shaking them slightly.
"No, no... that's not... I mean... Yeah, that was it..."
With him finally admitting it, Keebo could move onto the next part of his plan.
"Would you like me to help? Despite what I've said to Kokichi, I do have a dick... as well as other features that I believe may help you with the issue."
Keebo could tell that Sage was debating between saying yes or no. Keebo could tell when watching the videos that Sage wasn't as satisfied as he could be. He had confirmation from Mother Monokuma that the coast to the Love Suite building was clear so now he just had to convince him to come with him.
"You promise not to tell anyone, right?"
Keebo nods. It's not like he planned to tell anyone. What happens between him and Sage is for the two of them only.
"Okay... Do you think others will hear if we do it in my room...?"
"Yeah, I think so. Perhaps we could try the love hotel. I think if I tried I could hack us in."
Keebo could tell Sage was becoming more and more flustered as the conversation continued, so he had to get Sage there before he decided to back out.
"Wouldn't Monokuma get mad at us?"
"I don't think so. He said we're clear to explore the area to our heart's content, plus there isn't a rule about hacking to enter a room."
Sage seemed to finally give in with that final statement, and the two of them headed over to the love hotel. Keebo sent a message to Mother Monokuma to not record the events between him and Sage. No one would be able to see their escapades.
Inside the Love Hotel, it wasn't long before they had found a room they could stay in. The bed was pristine and the lighting was perfect.
"So um... shall we get started?"
Keebo nodded, leaving Sage to the bed. He began to help Sage undress. When tossing the clothes aside he could see the smearing of cum on his boxers. Naughty, naughty.
"Are you comfortable?"
With Sage's nod of approval and consent, Keebo could finally get started. First he started with warming his hands up; not too hot but hot enough so the metal wouldn't feel cold against Sage's skin. Seeing Sage squirm in anticipation, he raised his hands so that one was giving attention to each of Sage's nipples. He rubbed them between his hands, making Sage gasp. He tried to cover his mouth with his hands, but Keebo saw this and quickly put a stop to this.
"There's no need to cover up those beautiful sounds..."
Keebo noticed some handcuffs nearby in the room, and used that to keep Sage's hands still. Now that he was unable to resist, he gave Sage a soft kiss that became heated as it carried on. Pulling away, Keebo transformed his hand into a fleshlight, except he could make it vibrate. He noticed Sage's eyes looking in anticipation, and started it on a medium frequency, in addition to moving it up and down Sage's dick.
"A-Ah~ Keebo... I..."
Keebo loved the fact he left Sage at a loss for words, continuing to pleasure him. Given that he was already sensitive, it didn't take Sage long to orgasm. Even so, Keebo didn't stop.
"We're going to keep going all night. We have the time, so we might as well use it well..."
Perhaps some part of Sage didn't like the implications that he didn't have a choice, but with how he was feeling, he couldn't really say that he minded. Before long it was morning, Sage having been in and out of consciousness for the past couple hours.
Keebo stood up and gave Sage a kiss on the forehead before turning to leave. Sage noticed that he still had the handcuffs and called out in confusion.
"I'm sorry Sage, but I can't let you go right now. I have to make accommodations for you to be removed from the killing game. I'll give you all the pleasure you could ever want... in exchange, you won't ever leave me..."
Not giving Sage time to respond, Keebo left. He still had a killing game to run, but he was already looking forward to spending more time with Sage in the love hotel. He should be lucky he's excluded from the killing game, even more so that he'll get all the pleasure he wants. Guess his captivity is the payment he'll give in exchange for the pleasure Keebo offers.
