In a dimly lit Swiss dungeon, Carmela Tia, the young, eager pupil, is led by her instructor, Cello, through another day of rigorous deepthroat training. Gagged and bound, she's at his mercy as he slides his thick, veiny cock past her lips and down her throat. Carmela gags and chokes, but Cello persists, his grip firm on her hair. Her eyes well up with tears, but she's determined to master the art of deepthroating, swallowing every drop of Cello's salty cum, her German accent muffled by the gag as she moans in satisfaction.
