while Sienna is hot, her boyfriend seems like a decent dude, so unless they split I wouldn't do that. But it's unlikely it will happen either way
Sienna seems quite kinky both in the camp and bathtub scenes, maybe has a thing for Layla too.
And we have a Sienna points counter... unlikely but not impossible i think.
Oh god, I'm trying to think of how we get there from where we are at right now. Maybe a scenario where you stay with Layla and take her virginity and then the MC gets to slowly introduce that he likes them both (not sure how since the MC is conversationally challenged at best). Drunken escapade seems too easy. Sienna would be fun too but probably need Layla/Elena covered first.
Seems more likely to me than the scenario where you destroy Layla's heart...
In the "i prefer Elena" scenario... it's hard to come back from that, Layla is still a virgin and you just declared that you prefer her friend, she's always going to be the third wheel... It's hard to see her agreeing to have sex with the guy who passed on the opportunity.
If you deflower Layla, you never told Elena she's the extra, much easier to convince you like'm both equally imo.
On Layla's side she just lost her virginity, i imagine going forward she's gonna be a lot more open to trying stuff that she perhaps wasn't comfortable before (and in a perpetually horny state
), and those 2 never made a big stink about making out with each other... and sometimes it feels like she knows Elena also likes the MC, and different from other girls it doesn't make her jealous.
Getting drunk and having a threesome(that's more Alexis with Iris, i think) is too easy and not special enough, maybe a slow build up into them embracing bissexuality.
Once those 2 are covered maybe Sienna does a "special guest appearance", as i mentioned to
Elduriel she seems very kinky and maybe already figured out she's bi.
