A curious sissy explores the art of giving head, slipping a generous o-ring over their erection as a makeshift gag. They practice deep-throating, taking their time to get the angle just right, lips stretched wide around the imaginary cock. The room fills with wet, slurping sounds as they bob their head, learning to relax their throat muscles to take more. The o-ring glistens with saliva, a testament to their dedication in mastering the craft.
