Ok the FFM scene is the threesome with Mom and Julia.
To get it you have to:
But I doubt highly that scene is related to the Emma Pool and Rick sequence.
When you see her there, Do you get to grab her twice? If so then you probably already had that conversation but missed it by clicking too fast. It only happens once.
Go and talk to Kelly to see if there is a conversation about Emma feeling down.
If you get that then you had the Rick talk and will find her and Kelly at the pool on the weekends between 12:00 and 16:00. That will open up the workouts with Emma and get you another Threesome with Emma and Kelly.
