**Claiming Possession**

"Shizu-chan, you are mine," Izaya said, his voice low and husky as he leaned in to kiss Shizuo. "Only mine. You belong to me." Shizuo's eyes widened as Izaya's lips touched his, sending shivers down his spine. He tried to push Izaya away, but Izaya's arms wrapped around him, holding him close. "Don't try to escape, Shizu-chan," Izaya whispered, his breath hot against Shizuo's ear. "You're mine now. And I'm not letting you go." Izaya's hands roamed over Shizuo's body, sending sparks of desire through him. Shizuo's heart racing, he tried to protest, but Izaya's kisses grew more intense, making it hard for him to think. "I want you, Shizu-chan," Izaya said, his voice filled with desire. "I need you. Now." Shizuo's eyes fluttered closed as Izaya's hands pulled his underwear down, exposing him. Izaya's eyes gleamed with excitement as he looked at Shizuo's body. "You're so beautiful, Shizu-chan," Izaya said, his voice filled with admiration. "I'm so lucky to have you." Izaya's hands guided his dick into Shizuo, and with one swift motion, he pushed inside. Shizuo cried out in pain and shock as Izaya began to move, his strokes hard and fast. "Shizu-chan, you're mine," Izaya repeated, his voice a husky whisper. "I'm taking you, and I'm not letting go." Shizuo's eyes watered as Izaya's thrusts grew more intense, his body protesting the invasion. But Izaya didn't stop, his desire driving him to claim Shizuo as his own. "Harder, Shizu-chan," Izaya panted, his eyes gleaming with excitement. "Take it all." Shizuo's body trembled as Izaya's hands wrapped around his waist, pulling him closer. Izaya's strokes grew more intense, and Shizuo felt himself being consumed by Izaya's desire. "I'm...I'm yours," Shizuo stammered, his voice barely audible. Izaya's grin grew wider as he heard Shizuo's words. "Mine," he repeated, his voice a triumphant whisper. "All mine." Izaya's body tensed, and with one final thrust, he came, his body shuddering with release. Shizuo felt Izaya's warmth spread through him, and his own body began to relax, the pain giving way to a sense of exhaustion. Izaya's arms wrapped around Shizuo, holding him close as he drifted off to sleep. "You're mine now, Shizu-chan," Izaya whispered, his voice a gentle whisper. "And I'm not letting you go."
