Release: “A Childhood Friend and Younger Sister” by Tachibana Omina

Hina can’t be with the one she loves because he’s her older brother, but she also can’t let go of him. Her friend Hana, who is into the occult, lends her a mysterious crystal that can supposedly let someone switch places with another person for one day. Turns out the crystal’s powers are for real, and Hina ends up switching with Yui, her brother’s girlfriend.

A bodyswap between girls feels rather rare, and the threesome action was hot. I hope you enjoy it!

Release: “The Siblings’ Secret Nest” by Aoki Kanji

Koyuki and her older brother are in love with each other, but know that entering a relationship would bring hardship to their lives. Nevertheless, they work toward a future where they can be together.

Unlike Aoki Kanji’s other brother-sister incest works, this one stands out as taking the subject matter more seriously. Nevertheless, I hope you enjoy it! (If anyone is able to acquire better raws for Aoki Kanji’s COMIC Grape Vol.50 story, please let us know. I’d love to work on it, but I think we’ll have to pass on such low quality.)

The title says it all, really.

This story was the sixth chapter of Hinotsuki Neko’s tankoubon “Kinkyori Koubi” (禁距離交尾), but it seemed that the magazine version was a little better so we worked from those raws instead.

“Release”: “How To Raise Your Pet Sister” by Hinotsuki Neko

Mei’s hair flaps are cute. Apologies to people who wanted a real version–the other members repeatedly dissuaded me from doing so. As you can guess, yes, this is our April Fools prank; and if you don’t get the joke, the cleaning and typesetting is done in the spirit of the old, infamous “Great Teacher Onizuka” scanlations. A random sample of what that looked like.

Story aside, Izuna has unusually colored hair.
