That Ivy/Lena corruption of Holly path doesn't exactly comes prepackaged with a detailed description of what's going to happen, yes, one could expect she gets on the pole, Ivy goes full Major Payne on her coochie with her arsenal of toys and Holly opens up about wanting to suck dragons or whatnot, but the first time Ivy sends Lena some pictures of Holly with the Big Tuna guy I was like oh hell no and was set to trying to figure out a way to make her go that way, with the adequately high holly_change
variable, but without this particular thing occurring. It's a wild ride, I'll tell you that, so far my conclusion is at the mild variation Tuna still gets to feel her up somewhat, so now in my main save Holly stays home, far away from the sinful ways of the world or anything remotely like that.
