Nao-san (30) [English], an excellent vanilla hentai doujinshi parodying the Idolm@ster Cinderella Girls series, by Tachibana Roku (AKA Tachiroku)
Oh boy. Diabetes warning, the amount of vanilla is crazy.
Here is a very cute hentai doujinshi in which, Nao Kamiya, one of the Idolm@ster Cinderella Girls idols, is now aged 30, and living a happy life with her husband (guess who, we met him some years ago in Sunao No Nao) and their adorable little daughter. There’s just one issue, it’s super hard to find opportunities to have sex when your child is a light sleeper (an issue I’ve known fairly well).
With friends helping, former idols too, the wife and husband will finally have a chance, etcetera, of course – hey, it’s hentai. The hentai is drawn very well, with bearable censorship (multiple not too thick bars), personally seeing a hot MILF like that, knowing her teenage version for comparison, being so honest with loving sex, that was fantastic. Let’s add extra-thick eyebrows for the win.
And in terms of vanilla, there’s mutual love, mutual care, blushing, friendship, a cute child (don’t fucking misunderstand lol)… Haaa, that warmed my heart and soul
Long story short, a wonderful release! I am so grateful to LukasDMania, B4z73rd, MisterJ and Rikimtasu, from 1/2 Translations, great job!!

What kind of sorcery is this? A married couple doujin that keeps it’s vanilla flavor? I wish I had seen this one when it first came out. This and the new Akiko-san volume that showed up today translated really made my day,
Perhaps it didn’t go perfectly, but it did give Nao and Husbando even a little bit of much-needed “adult time”. Simply put, if more of that took place, whether in the 2-D world or IRL, there may be a whole lot more healthy relationships between partners as a result (just IMHO).
In conclusion:

Hold my Insulin boys, im going in!

Looking at the mom’s eyebrows, then looking at the dad’s; the poor girl had no chance in the genetic lottery. Looks like she better save up for eyebrow threading.
