I think the chief difference in the Maya vs Quinn scenes in question is that, for many, their MC was developing feelings for Maya, and only saw Quinn as an antagonist up to this point.
So, waking up to finding Maya climbing into bed with MC would not have seemed like a bad thing, even if questionable regarding consent.
Quinn, on the hand, would have been seen as 'ugh, not this bitch again...' when she climbed on MC's lap.
Now, flip MC's perception of the two, where they didnt warm up to Maya, and found Quinn strangely appealing in her frank and honest ways, then the Maya scene would have seemed more questionable, and Quinn's would have been more welcomed.
So really, comparing the two scenes is kind of pointless without bringing into context the player's MC feeling to both ladies.
