Blast from the past. Back when they weren’t afraid to include nipples on calendar artwork…
Back when they knew how to do ecchi right. More panty shots and nudity and less teasing. Even the calendar images would sometimes have nipples!
Here’s a random assortment of Koihime Musuo calendar scans as found on yande.re. Enjoy.
Please feel free to add your fav calendar scans to the comments. And leave a comment if there are other calendar(s) that you would like to see a blog post on.
