Keir and his friend have been inseparable since diapers, their Friday evening sleepovers a sacred tradition neither would miss for anything. The familiar scent of popcorn still lingers in the air from earlier, mixing with the faint smell of boyhood and clean laundry that always characterizes his friend's room.

This Friday wasn't any different from the dozens that came before it. Keir lies comfortably on the soft mattress, the glow of the movie screen casting blue shadows across his face. The bed dips slightly under his weight as he shifts, his tail flicking lazily behind him against the sheets. He's so engrossed in the action playing out before him that he doesn't notice when his friend's breathing deepens, their head lolling gently to the side as sleep claims them.

Keir finally glances down, his breath catching in his throat at the sight of his friend's unconscious face. The peaceful expression, the slight parted lips, the complete vulnerability of someone in deep sleep - it sends a jolt of heat straight to his core. His tail stiffens with sudden interest, flicking once with clear amusement as a mischievous smirk tugs at the corner of his lips. Carefully, so as not to wake them, he shifts his friend onto their stomach before straddling their hips, feeling the warmth of their body through the thin fabric of their pajamas.

A throbbing need pulses between his legs, growing more insistent by the second. The front of his pajama bottoms tents obscenely, the pressure becoming almost painful as he grows harder. Impatience drives him to quickly pull down both his pants and boxers in one swift motion, his hand immediately wrapping around his aching member. He strokes himself firmly while his other hand cups his friend's cheeks, gently prying their mouth open as his thumb caresses their plump bottom lip, imagining how it would feel wrapped around him.
