Re: Rem Plus

The hentai is based on the popular light novel and anime series "Re:Zero". This video was released by studio Grand Cross (Oreimo Plus, Azu Plus) in 2018. 

This video is something like a fanfic. The main character of the story marries Rem, one of the twin sisters who worked for Mr. Roswaal. This is his first night with an innocent girl. Although it's actually not at night. She has short sky-blue hair and huge juicy boobs. But most importantly, she is madly in love with the hero.
