**Chapter 21: The Unlikely Shift**

As Sangwoo continued to claim Jason's body, he began to pick up speed with his thrusts, his movements becoming more fluid and rhythmic. Jason's pain, which had been a constant companion since Sangwoo's invasion, slowly began to recede, replaced by a dull ache that seemed to throb in time with Sangwoo's movements. Jason's body, still tense and guarded, began to relax ever so slightly, his muscles releasing some of their stored tension as he adapted to the relentless pounding. But then, without warning, Sangwoo's cock hit a spot within Jason that made everything change. The pain, the ache, the discomfort - all of it washed away in an instant, replaced by a sensation that was both familiar and yet utterly alien. Jason's eyes went wide, his mouth opening in a soundless scream as his body reacted to the unexpected stimulus. And then, involuntarily, he moaned. The sound was loud and raw, a primal expression of the sensations that were coursing through his body. Sangwoo's eyes lit up with a fierce excitement, his movements becoming more urgent and frantic as he sought to repeat the sensation. Sangwoo hit that spot again, and Jason's body responded in kind. Another loud moan tore from his throat, a sound that was both a cry of pain and a plea for more. Sangwoo's face was a blur above him, his eyes gleaming with a hungry light as he worked to recreate the sensation. Jason's mind was reeling, his thoughts fragmented and disjointed as he struggled to make sense of what was happening. He had never felt anything like this before, a sensation that was both pleasurable and yet utterly terrifying. And yet, despite his fear, he couldn't help but respond to Sangwoo's movements, his body seeming to have a mind of its own. As Sangwoo continued to hit that spot, Jason's sobs began to fade, replaced by moans that were both a cry of pain and a plea for more. His body began to move with Sangwoo's thrusts, his hips arching upwards to meet the other's movements. He was begging, silently at first, and then more loudly, his voice cracking with emotion as he pleaded with Sangwoo to move faster, to hit that spot again. Sangwoo seemed to sense Jason's capitulation, his movements becoming more urgent and frantic as he sought to exploit the unexpected shift in Jason's emotions. Jason's body was responding, his moans growing louder and more insistent as he begged for more. He was lost in a sea of sensation, his body torn between pain and pleasure as Sangwoo continued to claim him. The world around him was narrowing, his focus drawn solely to the sensations that Sangwoo was evoking within him. He was trapped in a cycle of pain and pleasure, his body responding to Sangwoo's movements in ways that he couldn't begin to understand. And yet, despite his fear, he couldn't help but feel drawn to the sensations that Sangwoo was creating, his body seeming to have a mind of its own as it responded to the other's touch.
