A mysterious stranger presses against the glass, his hungry eyes locked onto Blanca Gar inside her apartment. He demands a dirty kiss, a 'beso negro,' through the window. Blanca, intrigued and aroused, plays along, feeling the heat of his breath as he leans in, his tongue sliding along the cool glass, leaving a wet, obscene trail. She watches, heart pounding, as he licks and kisses, his hands pawing at his crotch, until she can't take it anymore and retreats, leaving him hungry for more.
