Honestly the dialog & plot of that scene was worse than the AI.
I mean, holy shit it was so cringey... a middle school virgin who has only seen bad pornos could still have written something more believable. They guy basically shoves his dick in her without warning, lube or permission... and afterwards mumbles something about not wanting her to get the wrong idea about it. What kind of wrong idea? That it might have been rape? Or maybe she now thinks they are in a relationship?
And in the time it took for her to bend over to wipe the floor again, the MC got fully naked before penetrating her. As if we needed the dev to eliminate any aspect of believability from the scenario whatsoever.
The whole thing was worse than the "stepmom got stuck in the washing machine" porn trope.
