I mean, the very first image we see of the game is a blowjob. I don't know either who's sucking or who's getting sucked, and at first I was like "Oooh is this a NCIS reference where you get spoiled at the beginning with the gray filters?" but no it's just a very short-span flashback without any dialogue.
I wish good luck to the dev, Emma's body figure is my favorite so far. I just think the massive unrealistic and antigravitational breasts of the sister and the mother are a minus for this kind of graphics, try to cheat with some cleavages and sport bras maybe otherwise it'll look strange to me that women would accept beads of sweat flowing under their breasts while working out.
