Help confirm, please.

So there is information about an artist cg set on exhentai.com, adapted into a JAV. The artist cg set is http://exhentai.org/g/431701/afde8ec9c4/#cnew (for those who cannot access, search:[Hikari Club] 2051nen, Seikyouiku or [光クラブ] 2051年、性教育。)
. Can anybody confirm this information/give a link?

There's even some cg stuff on the back cover.
