“This is Kay and Yu from the game Haven. During the course of the game they find a book with erotica suggesting a few “interesting poses”. At some point in the story Kay suggests they may try a few of them. Yu states she wont be flexible enough for that, but if you follow yhe dialogue correctly she gets convince and tells Kay to “get the gear from under the bed, she will meanwhile do some stretch exercises”. The game never shows the scene so we went ahead and did so.”
