Under the soft glow of lanterns, they indulge in passionate kisses, their bodies pressed close, oblivious to the world outside. Seiya, on top, grinds against his lover, their breath heavy with anticipation. The cool mountain air does little to dampen their ardor as they explore each other's bodies, eager for the night's adventures.
