In the words of the dev in response to if Ellen and gramps had been intimate: "When Ellen turned 18, she essentially got the same treatment MC is giving the girls." I am more than happy to be wrong, not sure how else to interpret that statement though. We train the girls sexually, to be exhibitionists, in his sex dungeon to be submissive, and we sell pin-ups of them. The backstory might have changed since that statement and they were never intimate. I would gladly eat my words if that is the case.
