Honestly, I love that in both this and the previous one, the kid fills NTR roles and does stuff that usually scummy characters in hentai do maliciously, but he does it because he's just there to make people happy and have a good time.
Like, for example, when he shows her the picture of him and her son, in most hentai that'd be blackmail, just like she thought it was, but here he was just going "No, we definitely fucked. See? We even took this cute pic together!"
