Behind the gloryhole, a stranger's large, veined cock throbs, ready for the slutty ebony vixen's skilled mouth. She teases it first with her tongue, licking the length, tasting the pre-cum, before taking it all in, her mouth stretching to accommodate its size. She sucks with gusto, her head moving in a steady, greedy rhythm, her saliva coating the cock, making it slick and shiny. She pauses, pulling back to catch her breath, her lips glistening, before diving back in, eager to bring her anonymous lover to release.
