The more I think about it the less I think it'll go this way because it raises a lot of messed up questions (mostly assuming it wasn't a Skylar x Skylar x MC). The only "good" (non self NTRish) way for her and future MC to have banged would be that in that timeline she actually listened to her Mom and cut off contact but then never came to MC house to apologize? If that isn't the case then why would future MC want her? Is Skylar dead? Does Skylar not want to be around future MC anymore?That's also true, despite the NTRish of the whole situation (with yourself) is that the MC and Skylar's first time with each other wouldn't be at the same moment. Which is weird, among other weird stuff.
That assumes she goes to the future if she goes to to past it has to be within the past few years (due to age of consent stuff
