It's a lovely summer day. Momo's away at the Mekakushi Dan hideout, and Ene had tagged along, leaving Konoha and Shintaro alone in the Kisaragi residence.
Their hands are already all over each other before they even make it through the bedroom door.
Shintaro kicks the door shut with his heel, slowly edging Konoha towards the bed, never breaking away from the kiss. He tugs at his pants, struggling with the complicated belting (Hell, that thing could be used for bondage. He decides to keep it in mind for next time.) before Konoha giggles against his lips, pulling him closer to him as they fall to the bed. Shirts and jackets and pants are thrown carelessly onto the ground, until there was nothing left between them.
Konoha groans when Shintaro grinds his hips against his, the sheer pleasure making him have to push away. He drowns down a gulp of cool air before he starts sucking and biting on the other's neck, not bothering to hold back his squeals and whines as Shintaro thrusts against him, because they have the entire house to themselves.
Shintaro takes a shaky breath as his thrusts quicken, fingernails sinking into Konoha's pale, white skin as he somehow manages to pull them even closer. "Fuck, Konoha, I'm think I'm about to—"
They stop all movement the second they hear the front door slam open.
"Onii-chan! I'm home!"
Konoha clamps a hand over Shintaro's mouth and the another over his own as they listen to Momo's footsteps climbing up the stairs. "Onii-chan? Are you home?"
Shintaro can feel her presence right outside his door. Shit. He forgot to lock the door. If she walked in right now—
"Little sister!"
A new voice began talking from outside his room. A familiar one.
"Ene? What is it?" The rustling of cloth, and then the click of a lockscreen.
"Little sister, you left your homework at the hideout!"
He heard the sound of a bag opening and the rustling of papers. "Huh? What are you talking about? Its right here, in my—Crap! It's not there!"
A giggle. "I told you! Hurry up and go back, it's getting late!"
"Argh! Onii-chan, I'm stepping out again! Bye!"
Rushed footsteps make their way crashing downstairs, followed by cheerful laughter. They hear the front door fly open and shut with a loud crash.
Shintaro breathes a sigh of relief as Konoha removes his hand from his mouth. The cyborg squirms under him, trying to sit back up, but Shintaro holds him down, licking his lips with a smirk as the other stares at him with his pink eyes widened in slight suprise.
"We're not done yet, you know."

Ene returns half an hour after they finish, appearing in a cloud of pixels. Shintaro's still buck naked, body fluid still clinging to his skin.
"I'm back, Master." He looks up from Konoha's sleeping form, not flinching in the slightest as Ene's eyes roam up and down his body.
"Where's Momo?" Shintaro asks, standing up from the bed to make his way to the computer.
"Danchou invited the little sister to a sleepover at the hideout."
"And you're not joining them?"
"Hm, well. How much trouble would you have gotten in if I hadn't been there, Master?" Ene giggles, licking her fingertips. "I think I deserve a reward, don't I?"
Shintaro groans. Tomorrow was going to be an exhausting day.
