A tongue, like a snake, flickers out to taste the tip of a throbbing cock, drawing a shudder from its owner. The giver of pleasure takes their time, licking and teasing, before engulfing the length in their mouth, swallowing it whole. Spit and pre-cum mix, creating a lubricant that allows for a smooth, steady rhythm, punctuated by the sound of wet, hungry slurps and the occasional gag.
