Yes. I know our dicks/pussies are always eager to rub, stroke, slam, to explicit scenes, but having a bit of a tease, doubt, pace, makes the game more enjoyable in the long run. She is experimenting, being careful, shy even, because it is her first time doing this. It would be weird for her to suddenly be a nymphomaniac without any self control. The dev has to strike a difficult balance to be sure, between eroticism and pornography.
For me the scene with the friend from the past (playing volleyball and in the house), ex lover maybe, is hot, because you can see the wife has an internal conflict between desire and social mores, between her brain and her heart (vagina)
