In the privacy of his room, a submissive boy indulges in a secretive masturbation session, his eyes darting nervously towards the door. He's left the room barely ajar, a thrill of potential discovery adding to his arousal. His hand teases his hardening cock through his boxers, while the other reaches back, fingers brushing against the base of the plug nestled in his ass. He pushes his boxers down, letting his cock spring free, and begins to stroke, his breaths growing heavier as he fucks himself on the plug, imagining the touch of his dominant partner.
