A bit of a naughty idea

Hello everyone! I'm interested in establishing a roleplay idea that requires me and my partner to play as multiple people. Group scenes have just been super into lately and I want to put in the effort to make it work! I have some ideas but I'm also willing to discuss other options. So I won't bother beating around the bush and will list ideas here.

1. Fantasy party of adventurers.

2. Erotic camping trip

3. A daughter swap idea. (Legal aged of course, and we can brainstorm a specific scenario) 

4. Home invasion with a girl and her roommate. 

5. Anything else. I'm literally open for other ideas too!
