The room is filled with the sound of wet, sloppy slurps and the stranger's ragged breaths. They grip the chair's arms tightly, knuckles white, as the mysterious mouth works them over. The camera pans out, revealing a glistening, saliva-slicked cock disappearing and reappearing between full, wet lips. The stranger's moans grow louder, their body tensing as they approach orgasm. The mouth pulls back, allowing the stranger to finish, their cum splattering across their own chest and the armchair. The camera fades to black, leaving the identity of the mysterious mouth a tantalizing mystery.
