Yeah, I mentioned in a comment earlier about how the elf twins are basically the closest we really got to full blown NTR being in the game. The only thing stopping it from hitting is that... No one gives a flying fuck about the elf twins. If it were Miko and Mai, for example, you'd best believe I'd be on a warpath that would make Khorne himself smile ear to ear. But a bunch of actual whos that literally have zero relevance outside their quest?
*Yawn*
Though it was pretty laughable they were submitted during Mayternity. Wow, Savin and Skow, you really shouldn't have. No seriously, they'd be better off with a shitty update in the style of TiTs where it's 90% bugfixes and one sex scene.
I think the biggest issue with the elf twins, aside from their irrelevancy, is the fact they don't commit. It's the same bullshit we've been dealing with since this game's inception. If they're for >You, then they should be drooling over you and forgetting everyone else. If they're suppose to be sluts who let others breed them, then play up into it. But instead, it's yet another case of a character being stuck in the grey zone that satisfies nobody.
