**Chapter 3: The Agony and the Ecstasy**

As Dazai added another finger to Shizuo's ass, the larger man let out a pained hiss, his face contorting in discomfort. "Ah, fuck...that's going to hurt," Shizuo growled, his voice laced with anger. Dazai's expression remained calm, his eyes locked on Shizuo's as he continued to finger the larger man. "Relax, Shizuo," he cooed. "This will make it easier. I promise you, it will be worth it." But as Dazai added yet another finger, Shizuo's face paled, and he shouted angrily, "This is horrible!" His body tensed, and he tried to push Dazai's hand away, but Dazai held firm, his grip unyielding. "It's going to get better," Dazai said, his voice soothing, as he slowly pulled his fingers out of Shizuo's ass. Shizuo let out a sigh of relief, but it was short-lived. Dazai reached for the bottle of lubricant and coated his dick with a generous amount. Shizuo's eyes widened as Dazai positioned himself, the tip of his dick pressing against Shizuo's ass. "Owww, this fucking hurts," Shizuo said, his voice strained, as he gripped the bed sheet tightly. Dazai leaned forward, his lips brushing against Shizuo's. "It's okay, Shizuo," he whispered. "I need to fuck you and cum inside you. It's okay." With that, he pushed forward, his dick sliding into Shizuo's ass. Shizuo's eyes went wide, and he let out a pained cry as Dazai began to fuck him hard. Dazai's hands roamed over Shizuo's body, his fingers digging into the larger man's skin as he pounded into him. "Harder...fuck me harder," Shizuo shouted, his voice hoarse, as Dazai obliged, his thrusts becoming more aggressive. "Cum inside me...I want to feel it," Shizuo growled, his body trembling with a mix of pain and pleasure. Dazai's eyes locked on Shizuo's, his gaze burning with intensity. "I'm going to cum inside you, Shizuo," he said, his voice husky. "I'm going to fill you up." As Dazai fucked Shizuo harder, the larger man's body began to respond, his dick hardening despite the initial pain. Dazai's face contorted in pleasure, and he shouted, "Ah, Shizuo...I'm going to cum!" Shizuo felt Dazai's dick twitching inside him, and then a warm sensation spread through his ass, as Dazai cum inside him. Shizuo's body shuddered, and he let out a ragged breath, as Dazai collapsed onto him, his body spent.
