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.)

“Performance Complex” by Saemon

Yuuma’s little step-sister Mayu is better than him in virtually everything, so he has a massive inferiority complex and takes out his frustrations on her. When she gets the top score on the latest test results, it’s the last straw.

Unfortunately, the release is missing a page (15) because the scanner or uploader skipped it, and it’s unlikely it will show up anytime soon. If it’s any consolation, its absence hardly affects the story and may not even be noticed by many people.
