U should romance Callie and make her ur girlfriend first (picnic scene). Then romance Evelyn (don't romance her before Callie)How can I unlock 2nd scene of Evelyn and Callie?
I have already unlocked threesome at her store.
After that, tell Evelyn to go have fun with Callie and join them
next day, Callie will talk to u about it and the 2nd 3some scene will trigger on its own
