**Submission**

Shizuo Heiwajima stepped out of the luxurious bathroom, water droplets glistening on his massive frame as he dried himself off. He wrapped a towel around his waist and made his way to Izaya's bedroom, his anger and frustration simmering just below the surface. Izaya was waiting for him, reclining on the bed in nothing but his boxers, a smirk playing on his lips. "Shizu-chan, go lie in the bed and spread your legs if you don't want to end up homeless," Izaya said, his voice dripping with amusement. Shizuo's eyes widened in outrage, his face darkening with anger. He balled up his fist, ready to strike Izaya, but something about the situation stayed his hand. Instead, he slowly removed the towel and climbed onto the bed, his movements stiff and awkward. As he spread his legs, Shizuo's anger boiled over, and he growled low in his throat, his eyes blazing with hatred. "I hate you, Izaya," he snarled, his voice barely above a whisper. Izaya chuckled, his eyes glinting with excitement, and leaned forward to kiss Shizuo on the lips. Shizuo's eyes widened in shock as Izaya's tongue invaded his mouth, and he felt a surge of panic. Izaya's free index finger began to tease Shizuo's visible nipple in circles, and Shizuo gasped, his body responding despite his better judgment. "Very good," Izaya murmured, his voice husky with pleasure. He spit into his palm and moved his hand down towards Shizuo's rectum, thrusting a finger inward with a smooth motion. Shizuo's eyes went wide, and he let out a sharp cry of pain and shock. "Agh! Fuck, what are you doing?" he hissed, closing his eyes tightly. Izaya chuckled, his fingers moving in a gentle, soothing motion. "That wasn't so hard, was it?" he teased, his voice dripping with amusement. Shizuo bit his lip, his anger and frustration giving way to a growing sense of pain and discomfort. Izaya's finger moved deeper, stretching Shizuo's tight rings of muscle, and Shizuo shouted in pain, his body tense and clenched. "It hurts, it hurts, it hurts…" he repeated, his voice rising to a crescendo. Izaya's finger finally brushed against Shizuo's prostate, and Shizuo's fingers uncurled from the sheets, his body relaxing into the touch. Izaya smiled, his eyes glinting with satisfaction. "You're so tense, Shizu-chan," he said, his voice gentle. "But I'll make it better." With a generous amount of lube, Izaya began to stretch Shizuo properly, his fingers moving in a slow, gentle motion. Shizuo shivered and twitched as his skin became more and more sensitive, burning with a growing desire to be touched again. Izaya laughed, his eyes sparkling with amusement. "I'm sure I can make Shizu-chan feel good," he promised, his voice husky with excitement. He pulled his finger out and took Shizuo's member into his mouth, his hands fumbling with the lube until he finally opened it and smeared some of it on his fingers. Shizuo's eyes widened in shock as Izaya gently nudged one of his legs, and he felt a surge of panic. But Izaya's mouth was distracting, and Shizuo found himself spreading his legs, giving Izaya the access he needed. Izaya shoved a second finger into Shizuo's rectum, and Shizuo panicked, roughly pushing Izaya away. The man's teeth dragged across the skin of Shizuo's member, and Shizuo hissed in pain, his eyes flashing with anger. "Easy, Shizu-chan," Izaya soothed, his voice gentle. "I'm not going to hurt you. Not yet, anyway." Shizuo glared at Izaya, his eyes blazing with hatred. "You're going to pay for this, Izaya," he snarled, his voice low and menacing. Izaya chuckled, his eyes glinting with excitement. "I'm shaking in my boots, Shizu-chan," he said, his voice dripping with amusement.
