Personally, I think the whole point of putting Olivia in there is to have a believable way to develop a love triangle between Max, Olivia, and Lisa, especially when progress with Lisa is in the early stages where she is not willing to do much with max. Rather than focus on 1 on 1 content with Olivia, personally I think it makes a lot more sense to focus specifically on Max doing stuff with Olivia right in front of Lisa. I would also be in favor of some lesbo "experimentation" between Olivia and Lisa in front of Max. To me a story arc like that is a lot more believable than "Sex Ed" from either her mother or her aunt.Olivia is MOSTLY connected to Lisa. Eventually we may have things happen between her and Max alone, but at this point progress with her is tied to progress with Lisa. For now, the focus should be on Max and Olivia getting to know each other, and the growing friendship between Olivia and Lisa. Over time the character of Olivia can help Lisa become more curious and comfortable with SEXY fun ideas. While not as quick or easy a path as Kira, Olivia IS easier than the other ladies.
I have no objection to 1 on 1 content with just Max and Olivia, but I think she's much more interesting as a means to advance Lisa's story arc rather than focusing on a separate arc just for herself. I think developing it as kind of a cuckquean arc makes the most sense since that way you can make rapid progress with Olivia while maintaining more of a slow burn with Lisa.
