Meh, I dont think so. I mean, sure their personality is not as flashed out in the sex scenes than in the story-part, but IMO you can clearly see a difference between e.g. Penny, Annie, Nova and Alex during the scenes.
This has been my complaint about this game since the beginning, the "porn logic" here is RIDICULOUS and it hasn't gotten any better, the MC's magic penis that turns "virgins" into pro pornstars in literal seconds
after penetration is insane!
Cuz In one minute they are all like:
Ah! "Blushes" D-Don't call me cute, Baka!
And minutes later their next dialogue is:
Let me deepthroutht you into oblivion! FEED ME CUM!!!
The inconsistency doesn’t make sense!
I wrote about this being a problem since their previous game ages ago and Caribdis gave a liked... Maybe out of courtesy, maybe they agree that this part isn't their strong suit, who knows

Anyway, I think they at least recognize that this could be a problem for some
