While tentacles are not my cup of tea, the heroines in this make up for that tenfold.
At this point I don't know what I can say about this series that hasn't been said already. Known for it's more outlandish fetishes, this is sure to introduce you into kinks you didn't know existed, and crossing some lines for many of the genres tropes.
There are not a lot of scenes involving vanilla situations but the few you encounter are great, which to me it is a shame, as the heroines are so well done, so If you are curious I would get this, you can always skip what you don't like, but I would recommend doing so when it gets on a sale.
Otherwise if you are into the stuff in the tags, this may be a no-brainer.
There's also some gore, so tread carefully.
