**Chapter 29: Surrender to the Night**

Mitsuba's body was a moaning mess as he sat atop Kou, his muscles trembling with exhaustion and desire. Kou's hands grasped Mitsuba's hips, holding him in place as he continued to rail him with a ferocity that seemed to match Mitsuba's desperation. Their bodies moved in perfect sync, the only sound the wet slapping of their flesh and Mitsuba's incoherent moans. Kou's legs forced Mitsuba's legs to open as wide as they could, allowing him to penetrate deeper into Mitsuba's body. Mitsuba's eyes rolled back in his head as he felt Kou's cock hit new depths, his body screaming in pleasure. "C-cum! Cum inside me all night, won't ya? All fucking night, make me reek of you, Kou~ ah~! Ahh~!!" Mitsuba's voice was a hoarse cry, his body tensing as he reached the peak of his orgasm. His cum shot out, covering Kou's chest in a sticky, warm mess. Kou's eyes locked onto Mitsuba's, his gaze burning with a fierce intensity. He could feel Mitsuba's body milking his cock, drawing out the cum that he had been holding back. As he looked at Mitsuba, Kou saw a deep-seated surrender there, a willingness to give himself over completely. "Ah, Mitsuba... you're mine," Kou whispered, his voice low and husky. "All night, all day, every day... you're mine." He emphasized his words with a powerful thrust, his cock reaching deep into Mitsuba's body. Mitsuba's eyes fluttered closed, his body going limp as he collapsed onto Kou's chest. Kou wrapped his arms around Mitsuba's back, holding him close as he continued to move inside him. The warmth of Mitsuba's cum on his chest was a reminder of the intense passion they had just shared, and Kou knew that their relationship had changed forever. As the night wore on, Kou's movements slowed, his body sated but still craving the warmth of Mitsuba's skin. He could feel Mitsuba's heart beating against his chest, a steady rhythm that seemed to match the beat of his own heart. "You smell like me, Mitsuba," Kou whispered, his voice a gentle tease. "You reek of me, and I love it." Mitsuba's body stirred, his legs shifting as he tried to get comfortable. Kou's hands roamed over Mitsuba's back, tracing the curves of his spine as he held him close. "I think I'll keep you like this, Mitsuba... all night, all day... forever." The words were a promise, a vow to never let Mitsuba go. And as Mitsuba's body relaxed into his, Kou knew that he would do everything in his power to keep that promise.
