He trails his fingers down the other man's chest, leaving reddened trails in his wake. "I gave you what you wanted, didn't I? A taste of the high life, a roof over your head, protection from those who would do you harm and what not."
He looks into Dokyeom's eyes, his own filled with icy disdain. "But you had to go and fuck it all up, didn't ya?" he says, his tone deceptively calm. "Couldn't keep your pretty little mouth shut and just do as you were told."
Dokyeom whispers, tears falling from his eyes rapidly. "I'm...sorry."
"Sorry?" Joshua repeats incredulously, his hand stilling on Dokyeom's chest. He leans down, nose almost touching his, and sneers. "That's cute, baby boy. Real fucking cute."
Joshua chuckles darkly at Dokyeom's apology, the sound sending shivers down his spine. He pulls out of him without warning, letting Dokyeom collapse onto the bed with a muffled groan. Grabbing the man's chin roughly, he turns his face towards him. Dokyeom looks at him confused. 
"Sorry doesn't cut it, sweetheart." Joshua says coldly, his thumb rubbing circles around Dokyeom's bottom lip. He pushes it inside the man's mouth briefly, making him gasp before removing it. "You know what does, though? Showing me how much you appreciate what I do for you."
"H-how?" Dokyeom asks, wanting to please him in any way. "How, you ask?" Joshua says with a cruel smirk, releasing Dokyeom's chin. He stands up, towering over him like a dark shadow, and saunters over to his dresser. Opening the top drawer, he takes out a small black box and walks back to the bedside, casually flicking it open. Inside is a set of nipple clamps connected by a thin chain.
Dokyeom whimpers at the sight of the clamps, he crawls back, clearly scared of it. 
"Oh now, where's my good little pet going?" Joshua purrs menacingly, reaching down to grab Dokyeom's arm and pull him back into place. He climbs on top of him once more, knees pressing into the mattress on either side of his hips, caging him in completely.
"H-hyung please no, it'll hurt." Dokyeom pleads. "Course it will." Joshua replies nonchalantly, grabbing one of Dokyeom's nipples between his thumb and forefinger and twisting it sharply. "That's kinda the point, ain't it?" His voice drips with venom, but there's a hint of amusement lurking beneath the surface.
Joshua's eyes narrow as Dokyeom begs, a sadistic glint appearing in them as he watches the fear and pain dance across the other man's face. He leans down, biting hard on Dokyeom's earlobe and growling, "You're lucky I want you at all."
"Hyung please, why are you doing this? Stop." He cries. Joshua laughs coldly at Dokyeom's cries, enjoying the way his body trembles beneath his own. 
He sits up and yanks the clamps out of the box, pinching one of Dokyeom's nipples again before attaching the device with a sickening snap. The younger man arches off the bed with a strangled cry, his eyes squeezed shut as tears stream down his cheeks.
"Why am I doing this?" Joshua echoes with a mocking pout, attaching the second clamp with equal force. He tugs on the chain between them, eliciting another agonized cry from Dokyeom. "Because you've been a bad boy, and bad boys need to learn their lessons." He traces the line of tears with his thumb, licking it clean afterwards.
Joshua studies Dokyeom's tear-streaked face for a moment, feeling an odd mixture of satisfaction and something else - something he quickly squashes. He leans down to press a rough, possessive kiss against his lips, tasting salt and desperation. When he pulls away, he murmurs against his skin. "And because I fucking own you."
Pulling back from Dokyeom's lips, Joshua gazes at him with a calculating look. He knows that Dokyeom craves his attention, even if it comes with pain and humiliation. He wipes away some of the tears with his thumb, his expression softening ever so slightly. "Look at me, baby boy." He orders gruffly, waiting until those beautiful brown eyes meet his own.
