In a split second, the scene shifts from casual to carnal. A hungry mouth descends upon a rigid cock, engulfing it whole. The sucker's tongue explores, tasting every inch as they slide back and forth, quick and eager. The cock responds, throbbing and twitching, until it can no longer hold back. It erupts, painting the insides of the mouth with hot, sticky cum. The recipient swallows greedily, relishing the warm, salty load.
