With a deep breath, he steps out into the open hallway, the vibrating ring already humming against his sensitive flesh. His heart races, not just from the taboo thrill, but from the sight of his own massive, engorged cock, the head glistening with pre-cum. The cold air bites at his skin, contrasting sharply with the warmth of his body, as he begins to stroke himself. The risk of being caught at any moment only serves to heighten his pleasure, his strokes becoming more urgent, his moans more desperate. The vibrator's insistent buzz pushes him closer and closer to the edge, until finally, he can't hold back any longer, his body tensing as he spills his load onto the cold, hard floor.
