Zack's breath hitches as the stud's fingers brush against his virgin anus, sending shivers of anticipation through him. The stud leans in, his hot breath on Zack's hole, before planting a soft kiss, then a firm lick, his tongue exploring Zack's tight, puckered entrance, driving him wild with desire.
