The ebony beauty's large, dark eyes gleam with lust as she gazes up at the mysterious cock before her. She can't see the man it belongs to, but she knows he's enjoying her talents. Her mouth is a warm, wet haven, her tongue dancing along the ridge of the head, tasting the pre-cum that beads at the tip. She takes it deep, her throat muscles relaxing to accommodate the length, her hand pumping the base in synchronization with her mouth. The man on the other side of the wall groans, his hips bucking slightly, urging her on as she blows him, relishing every moment of this forbidden, anonymous pleasure.
