A harem, by definition, is out, but Lena can certainly have a pretty large staple of female booty calls and none of the other girls seems to mind. As I'm sure you're well aware
. And a lesbian orgy isn't quite as far fetched either considering there has already been two threesomes and that's before getting into the possibilities of Eli, Emma, and very likely, I think, a submissive Louise.
Tangentially related, I have strangely high hopes for submissive Louise. I wasn't a big fan of submissive Eva from GGGB, but I think that's because the only real thing that changed between submissive and loving for her was getting Jess to join the lesbian threesome. But so far a sub Louise has had a much different set of interactions with Lena and during the threesomes with Mike and Ian. And my disappointment that Louise and Ivy have not interacted since Lena let it out that she was domming Louise is equally high. Ivy will do way more with that information than Jess did, even if it's only limited to a sex scene.
