Given this is early in the game, I would suggest some alterations to this story and gameplay.
The mind control aspect seems poorly developed, making it a percentage also makes it feel mechanical and no one really likes sex scenes that involve a menu selection, that kiss with the mom was hotter than the scene with the aunt because it happened within the story, not from a menu.
If it's not too much trouble, change their sexual desires increasing to be a side effect of the super hero formula, they have increased libidos and the protagonist needs to take care of those desires or else they will go on a rampage. The start where the moms on the phone could be some weapon to fry the brain and the experimental superhero formula was the only way to save her.
