I get what you mean... I guess. And it's true Pussy seems to fit the best in this situation. We as Germans often don't have the best words to describe such things I guess. Cause: "alles muss seinen korrekte nahmen haben!" Oder so....
Nene as a character from what she sais in the Scenes and the dialogues is genuinely curios and a kinda always horny person Sex is some kinda Normality in her Daily life since she's not a bit spirited over one of thebintercourses or engages them by herself. The part with Linnea is the part where I took my inspiration from I a personaly like it verry much I think the Kinda playful and genuinely immature but also sexual experienced behavior of Nene get's portrait pretty well by this Dialoge and intercourse text.
