Thanks for the report.
The fact that you see the ogre and not the image of a "mysterious man" is another mistake for which I apologize (but I already fix it in the new update)
Instead the quick solution to your problem is to skip the first part of the 4th minigame and go directly to the final erotics scene. (At the beginning of the game it asks you if you want to skip the first part)
I'll fix this bug as soon as possible ; )
