The guild's library, usually a sanctuary of quiet and knowledge, becomes a den of lust as Natsu and Gray succumb to their forbidden attraction. Natsu's dragon slayer mark blazes as he watches Gray study, his eyes lingering on the curve of Gray's neck, the way his shirt stretches across his broad shoulders. Gray feels the heat, looks up, and catches Natsu's gaze. He smirks, stands, and walks over, his intention clear. He pushes Natsu against the bookshelf, their lips crashing together, bodies pressing tightly. Natsu's hands roam, exploring Gray's body, while Gray's hands grip Natsu's ass, pulling him in closer, their cocks straining against their pants, ready to set the library ablaze with their gay lust.
