Don't disagree about the rape part, it does kinda come without warning. Luckily none of the phone date options block progression.
Where I'd disagree is that F/F hasn't really been traditionally considered part of the cucking genre, especially when you are looking for it in porn. I think it's a minority view point, I don't think many straight men consider another woman a threat to their relationship. Whether that's ego or not is arguable, but given how popular FFM threesomes and lesbian porn is with straight guys, maybe we're arrogant in thinking watching our girl with another woman will lead to a threesome. But it is definitely not something the mainstream feels threatened over, they aren't making those videos for actual lesbians, that's for sure.
Yeah, the Mimi/Alice sex scenes where she's uncomfortable is another indicator. But again, you have to press buttons to initiate those, so there's an opt out.
