Blindfolded and bound, the sub squirms in anticipation. The dominant's fingers trace along the sub's lips, a silent command. The sub parts their lips, allowing the dominant's cock to slide in. They moan, the vibrations sending shivers down the dominant's spine. The dominant guides, the sub follows, their movements synchronized, a dance of trust and desire. The room echoes with the sounds of their pleasure, the sub's muffled moans against the dominant's cock.
