Two brothers, Phi and Choi, find themselves alone in their dimly lit room, the air thick with tension. Choi, the elder, can't help but notice Phi's growing curiosity, his gaze lingering a little too long on Choi's body. As they share a bed, Phi's hand accidentally brushes against Choi's crotch, feeling the growing bulge. Choi, surprised but aroused, doesn't pull away. Instead, he turns to face Phi, their faces inches apart, breath hitching in sync. The room is filled with the sound of their labored breathing and the soft rustle of sheets as they tentatively explore each other's bodies.
