Started the game up again to check:

For the Kat scene:

• Work as a waitress
• You have to get all the drinks right (The patrons will grope more and more)
• Then select "Stay after closing the bar."

For the Ahri/Sona scene:

• Go to the sex shop
• Select "Buy sex toys."
• When the toy selection screen is up, click on Jinx
• For me the choice is "Backroom..." but it could be different for the first time, I don't remember.

The scene with Katarina you get by working at the tavern, for the other one you have to talk with Jinx (click directly on her).
