Carmela Tia, the eager student, returns for her fifth day of intensive oral pleasure training under the watchful eye of her stern instructor, Cello. Gagged and bound, Carmela's delicate mouth is forced to accommodate Cello's massive, throbbing cock.

Carmela's eyes water, but she's determined to please, eagerly swallowing every inch until Cello unloads a thick, creamy load directly into her waiting mouth.
