The plot is that Matsushita Ukyou (your protagonist) and his mother have been called out to visit the shrine run by his grandmother Touka, and not long after, finds out that (A) he needs to take over training the shrine maidens and help select the next one and (B) he's going to have to wind up doing This and That with at least one of them in the process.
Chichi Miko!! Plus 1 ~Grandmother and Daughter Milking Harem~ Release! is the first spinoff (also translated to English by Lv1 Translations).
- Gag Boobs: They START at this level and only get more insane from there.
- Parental Incest: And even GRANDPARENTAL incest.
- Taken Up to Eleven in the spinoff where your own daughter gets involved.
- Grandma, What Massive Hotness You Have!: The above trope is only slightly less horrifying given this is also in effect, though the incest theme may still be major Squick.
- Hot Dad: Considering that even when older in the spinoff he still barely looks old enough to shave, Ukyou would count without question.
- Hot Mom: And guess what you get to *ahem*, do with her.......
- Hypocrisy: Pointed out in the spinoff between Kyouka and her father. He weakly tries to shoot down an incestuous encounter between them on grounds of impropriety, but she points out that she knows he and her mother are blood related and that his arguments are nonsense.
- Incest Is Relative: Do we really need to elaborate on this one?
- Kissing Cousins: Rinka is your first cousin
- Meaningful Name: Your protagonist's family (and childhood friend/cousin) operate the Milk Shrine. Three guesses why it's called that, and the first two don't count.
- Miko: Albeit all of them are Nun-Too-Holy.

- This isn't seen as nearly taboo in Japan as it is in certain parts of the West, though the family connection is still pretty direct.
