I have to disagree about it being out of character for Fiona, given how she was with Mary and the MC at the beginning - sure she was used to being the Dom, but you already taught her she's a switch, which is how your whole relationship with her started. For the other, I can see how one might think it was out of character, however With Becca you have to remember you're still really learning who she is. The stuff that she was super turned on by the fact that the incest with her is incest was a big shock, at first for me. I suspect all the characters still have surprises in store.Great update - as usual - but TBH I have to say I'm not particularly convinced by the last scene.
I admit it's probably me (I'm non into BDSM at all, actually I pretty much hate it), but overall it seemed like coming out of left field, and IMVHO it felt a little bit out of character for both women involved.
Not a big deal, though: next time I replay the game I'll just have to skip it
Other than that, kudos to Killer7 as usual
