Spot on. I'm very much into the same experimentation stuff. Like Ian and Lena talking openly about involving other women in their lives, like I'm seeing a holly possibility. But for fun, I don't want to see a throuple relationship though, just both of them involving other women one by one into some bedroom fun. Although if a throuple relationship is the only way to get a threesome scene path between Lena and Ian, I wouldn't mind it i guess. But yess the experimentation part is very less as of chapter 12 i think. That needs to increase a lot more.
I haven't played the open relationship route yet, so I don't know what content Eva may have removed from that in the current update. But prior to this, there was already a threesome scene involving Ian, Lena and Louise on that route ( with Mike substituted for Ian on the cuck version). I'm pretty certain that scene was specifically aimed at the experimentation/open relationship route, because Lena tells Louise beforehand, that Ian's biggest fantasy is having sex with two girls ( he told everybody this during Ivy's party) and she wants to make it happen. At the end of this scene ( if Lena suggests her fantasy is having sex with two guys), she asks Ian if he'd help her make this happen, and he says he'll think about it. So I assume that will eventually happen on the open route ( and my guess is, Jeremy will be the other guy, especially if Ian also knows that she has a Big Cock fantasy).
I think it's inevitable, that on the open route there will eventually be threesomes, with Ivy, Holly, Emma, Jessica, Jeremy, Billy and possibly Mark, Mike and Alison. It's never going to happen though with Axel, Seymour, Jack, Robert, Cindy or Cherry.
I think some of those, could also be foursomes, and there might even be the odd gangbang/orgy?
I think there'll also be more instances of public sex, Ian fucking Lena on Stalkfap, and perhaps the two of them even getting involved in Porn?
