Another NTR focused release.
The characters are the same as the ones from the “Yokoshima vs Fushidara” and “the great escape”, namely Ai-chan and the Manager. The manager tricks Ai-chan into a weekend date with him by inviting her to a non-existent company outing. You can probably guess how the story goes from here.
The doujinshi features a bunch of nice illustrations as well again.

As of right now I have no plans to translate further entries in the series.
Too bad, I would really appreciate a quality translation of the Himitsu series
