We continue Maria's training. As usual, we planned to start with an enema, but since today's session is in a special location, inserting the nozzle seems difficult. The showerhead cannot be removed, so we have no choice but to consider an alternative method. Without a glass syringe available, we decide to change our approach. First, we apply vaseline to her anus and use fingers to massage and loosen the area, then insert a 3-prong anoscope to widely open the anal canal. Inserting the anoscope, we grip the handle and slowly expand it by turning the locking screw. After returning to the room, we restrain both her arms and attach a fixed vibrator to begin serious training.
