A brave soul ventures into the unknown, inserting a thick dildo into his urethra at the command of his dominant mistress. His legs tremble as the toy slides in, inch by inch, stretching his sensitive opening. The femdom, delighted by his discomfort, encourages him to take more, pushing the dildo deeper until it disappears entirely. The sight of the bulging cock, filled with foreign object, is a twisted turn-on for both parties.
