Here is some assorted fun stuff to get Ariane out of her clothes at her home.

This path is available in the help section of the game. On the main menu click “Help” then click “Paths” on the top row, and next to where it says “Striptease at home” click “Enable”, then load up a save of pizza dinner or steak dinner. Correct choices will be highlighted in Magenta. Note: Where there is more than one choice, you might have to do one, then the other when you get to the choice page again. If you did not save an opening, enable “Pizza Dinner” or “Steak Dinner” as well and start a new game from the beginning.

Begin first by following Pizza Dinner or Steak Dinner.

Go to the living room
Massage her shoulders
Go somewhere else
Go to the backyard
Check out the telescope
Can I have a look?
crater A
  or sea D
  or Another planet crashed into earth…
  or 12, I believe
Watch her
Change into a swimsuit
Follow her into the bedroom
Go inside
Dance in the living room
Pick a HipHop playlist
Take yours off too (if playing as a female)
Keep the rave going
Take yours off too
Go somewhere else
Go to the living room
Kiss Her
Massage her back
Touch her pussy
