IMO, the success chances for this scene are ridiculous without save scumming. In my game my massage success chance is less than 20% and you have to succeed twice in a row so that's a 4% chance there, and then there's a final check after that which is closer to 50% for me, so roughly 2% chance of success for the full scene. That means on average I would have to do that scene 50 times to have a decent chance of succeeding, and you have to succeed 3 times if I remember right.
