Have your ever read about this subject? Because thats exactly why. They dont understand whats is going on, they dont have a body or mind prepared for that, that can lead to a lot of misunderstandings (never heard a story about a kid saying that daddy was hurting mommy?), traumas, inapropriate sex behavior later and a lot of other even more serious shit. Even while reading Yaoi we come across a lot of plots when the MC sees his mom having sex and develop some sort of trauma or messed up behavior. Im not saying this because Im "conservative", Im saying because its real and it matters for mental health. (And Im sorry if I cant explain propoerly, english isnt my first language)

Never said it was easy to have private sex with kids around (≧∀≦) But kids are super smart and curious and they notice everything, so we need to pay attention. Educating and raising kids isnt an easy job, especially when we try to think about whats best for them and start researching about it (〜 ̄△ ̄)〜
This is really good BUT ... They did all that sexual stuff in the same bed the kid was sleeping when they were at the hotel... Seriously... I know this is just a manga, but I hope everyone that read this know that it isnt healthy for kids to be exposed to sex when they are so young. So, remember to have safe and PRIVATE sex when near kids, guys! (▰˘◡˘▰)
