There's a hentai I don't have anymore and would like to watch again but I forgot the title. I can describe it pretty well though, any help on finding the title would be appreciated.
It has a pretty distinct art style, it looks less cartoony than most hentai OVAs, it has pretty detailed faces on the females while the males look very bland. It's about a girl who would do anything for her brother, which he uses to whore her out to his otaku friend at first, and to the entire neighborhood at the end while filming. He himself makes her suck him off repeatedly, even during a call (I think they were ordering pizza). There's also a scene set in a shack at the school the girl attends to, where one of her friends gets banged by another student. I also think the brother and his friends never say a single word in the entire OVA, so its mostly the sister talking.
There's also a preview of the next episode, however, I think that one never got made so it remains a one-off OVA. Oh, and it also had one of those short titles that end with an exclamation mark if I recall correctly.
今年の12月があなたにとって幸せで素晴らしい月になりますように！
