**Chapter 14: Boundaries Crossed**

The haze of pleasure had barely lifted when Hyunjin's expression turned mischievous, his eyes sparkling with a hint of playfulness. Bangchan's instincts screamed at him to be wary, but his body still felt languid from their earlier encounter. He hadn't even had a chance to process the intensity of what they had just done. Hyunjin's gaze wandered to the bedside table, where a small, unassuming package lay. Bangchan's eyes widened as Hyunjin picked it up, his heart sinking as he realized what it was. A silicone buttock, its lifelike texture and appearance making Bangchan's face go pale. "Hyunjin, no," Bangchan protested, his voice laced with unease. But Hyunjin's expression was unyielding, his eyes glinting with amusement. "You know the rules, Bangchan. You lost the bet. Now, it's time to pay up." Bangchan's face burned with embarrassment as Hyunjin held out the silicone buttock. It was a punishment he had never expected, and his body tensed in reluctance. With a sigh, Bangchan took the buttock, his hands hesitantly cradling it as if it were a fragile egg. Hyunjin's eyes watched him, a wicked grin spreading across his face. "Now, use it," Hyunjin commanded, his voice low and husky. Bangchan's face twisted in discomfort as he tentatively began to use the silicone buttock. The sensation was surreal, and he couldn't help but feel a twinge of humiliation. As he moved, Hyunjin's eyes never left his face, a question burning in his gaze. "Is it better than my hole?" he asked, his voice low and suggestive. Bangchan's response was a vigorous shake of his head, his eyes wide with desperation. He wasn't even sure why he was trying to come; it was as if his body had taken on a life of its own. The room was silent, the only sound Bangchan's ragged breathing and the soft rustle of the sheets as he moved. His face was a mask of concentration, his body tense with need. Hyunjin's eyes watched him, a wicked glint burning in their depths. He seemed to be savoring Bangchan's discomfort, his expression twisted in a mix of amusement and arousal. As Bangchan's movements grew more frantic, Hyunjin's grin grew wider. "You're not even close, are you?" he teased, his voice low and husky. Bangchan's response was a strangled gasp, his body tensing on the edge of release. But just as he was about to come, Hyunjin's voice cut through the air, his words like a dash of cold water. "Not yet, Bangchan. You're not done."
