In a twist on a common kink, Manuel's wife challenges herself with dental floss, wrapping it around her teeth before taking his massive cock into her mouth. She works her way down, inch by inch, until she's gagging on his length. The floss cuts into her gums, heightening her sensation, as she sucks him with renewed vigor. Manuel watches, entranced, as she struggles and moans, pushing herself to take him deeper than ever before.
