She begins by verbally demeaning him, her dirty talk fueling his humiliation. She then produces a urethral sounds, cold and menacing, and orders him to hold his piss. As he struggles, she inserts the tool into his virgin pisshole, stretching his urethra. She twists and turns it, causing him to squirm in discomfort and pleasure. She then orders him to release, and as he does, she milks his pisshole, extracting every last drop.
