During the anal part of the sex scene with Galaxina the dialog partially makes no sense (and I don't mean the humor kind of no sense). She puts on the condom,then there is a sex animation, then she takes off the condom, then the raw penetration acts like no penetration has happened before and they talkabout the condom being lubricated (even though it was already taken off)
Or maybe she just acts like it's still on, but she told the MC beforehand, or was that supposed to be a thought, not spoken?
