no, sorry, you misunderstood me. I should have written a better explanation. I literally meant that it happens because of his dick. if the girl isn't horny to being with, and doesn't initiate things and didn't really want to do anything. it's his dick that fills them with lust and hypnotized them. Haley got it too for example. usually, the girls all come on strong and MC is just passively accepting them.You got me curious, so I went check replays in S1 and S2. I see only Misty and Tamara have their eyes turn pink during sex, so definitely not all of them, unless you mean the single frame of creampie from MC's imprinting? Like, Torr has very consistent green eyes in any of her sex scenes.
the one scene where it should have happened but didn't is when Jenny sees it for the first time in the closet and is surprised. though you can argue that she was already under MC's spell having spent years growing up with him.
maybe his godhood is amplifying his lust inducing curse.
