Since Chapter 13 is the last one, I think these threesome or foursome must happen
These are interesting suggestions!
Ophelia x Brenna x Catherine
Not high on my priority list, but this seems like a must-have scene.
At least Ophelia x Drew, perhaps some kind of confrontation about the affair. Aliza could make it interesting, all three sisters. I'd be fine if Sterling was absent, but a foursome would be epic.
Would love to see them with Sterling. Almost happened this chapter. Next time baby!
Catherine x Amber x Rebecca
The friend group. This could be fun.
This would be nice, but almost too... predictable? I think I might rather see these two in a bad end threesome.
Ophelia x Mallory x Aliza
Mallory
needs a scene with Ophelia, and it seems the game is building up to it. Aliza could maybe sit this one out?
... I might add Ophelia x Nora (possibly with Keira).
Ophelia and Nora could share thoughts about how having sex with Sterling is so much better than having sex with David. I suspect Keira may have been part of that as well.
