From 2D Market:
Since we’ve last seen them in the prequel, Nene and the silent protagonist have gotten married.
In this book they take a trip to a fancy hotel and decide to hop in the hot bath together.
They both came prepared: Nene wore a micro-bikini under her bathrobe, while the protagonist brought a whole bottle of lube.
Watch the incredibly hot scene as it unfolds in this steamy doujinshi.
