I wouldn't mind a minigame with some girl, to undress her or make her cum or whatever that is connected to what the game is about, but anything as stupid as "click as fast as you can to fill the bar" is just a heavy turn off and should have no place in this type of game.
Edit: Actually in the game about drawing it would be very nice to have interactive drawing or sketching minigame where you could focus on some part of the model's body and see a closeup. Or you could go to her for a moment and touch her to make slight pose corrections, trying to get her turned on. Then maybe ask her to gradually remove clothes and so on. There are many things you could do to make it interesting. Instead we get completely unrelated retarded clicking tasks with only two outcomes, success or fail, with "rewards" being memories that would be logical to access without any minigames at all.
