Rantaro smirked, his arms crossed as he leaned against the mid-grey doorframe. Shuichi matched his stance, an equally amused smirk on his lips. In the dim room that they were observing, a naked Kokichi moaned into the bed whilst shoving a dildo in and out of his ass. The small, deep-purple-haired man hadn't noticed that he had an audience as he faced the headboard. Neither witness was complaining about the sight.

Nudging Shuichi with his elbow, the two locked eyes and nodded. Rantaro's pants were tight, begging to be removed. If he had to stand back and watch any longer, he'd implode. Shuichi dramatically cleared his throat.

Kokichi yelped, flipping around and staring at the two with wide, deep-amethyst eyes. His cheeks flushed a deep red. "O-Oh! Um, h-hey! I didn't expect y-you two to be h-home s-so soon!" Chuckling, Kokichi rubbed the back of his neck to release the nerves. Neither Rantaro nor Shuichi uttered a word, their mischievous grins prominent.

In an attempt to cover up his naked body, Kokichi sat up and gripped the sheets. His knuckles turned white as he moaned, knees bending to his chest. He'd forgotten that he still had a silicon object inside of him. Rantaro took this moment to begin approaching like a predator stalking its prey.

"What do you think you're doing?" Rantaro chuckled, keeping his voice low. Kokichi averted his gaze, staring at the crumpled light-brown sheets.

"I thought our rule was clear that you couldn't touch yourself without our permission," Shuichi spoke up from beside Rantaro. "Did you ask permission?"

"N-No..." Kokichi mumbled. The lock of deep-plum hair falling over his face concealed his eyes. Rantaro knew the other felt guilty because it rubbed off on him a little. He'd rarely cared about others, but Kokichi and Shuichi had changed him. Despite Shuichi's occasional violent outburst towards strangers and Kokichi's frequent meltdowns, Rantaro loved them to pieces.

"No what?" Shuichi encouraged.

"No, Masters..." Kokichi pursed his lips, bowing his head in shame.

Rantaro reached the bed, picking up the small man and flipping him onto his stomach. Spreading Kokichi's ass, he grabbed the hilt of the toy and thrust it hard. Kokichi moaned and gripped the mattress protector in his fists. One of the corners slipped out from its snug tuck, flicking into Kokichi's hand.

As Rantaro continued to toy with Kokichi, Shuichi reached underneath the bed. He slipped out a small shoebox from behind the light-brown sheets. Watching carefully, Rantaro noticed Shuichi pulling out a thin, black rope from the box. Resting a knee on the bed, Shuichi made quick work of tying the purplette's wrists together. It looked a little painful, but Kokichi's skin wasn't bulging beneath the fabric.

Kokichi whined and jiggled his hips as Rantaro pulled out the toy, dropping it to the bed with a faint thump. Hurrying to shove his navy jeans and black boxers down to his ankles, Rantaro picked up the light male. It wasn't difficult as a feather weighed more than Kokichi. On top of that, Rantaro wasn't weak by any means.

Struggling slightly, he finally managed to slip his dick into Kokichi, making the smaller moan and bend his knees in the air. Rantaro bounced Kokichi, thrusting whenever he could to deepen his movements. Kokichi threw his head back onto Rantaro's shoulder, his hands gripping and pulling the greenette's shirt with desperation.
