Summary:
弱い魔術師の女の子が必死に戦おうとして負けて仲間の子と一緒に丸呑みにされちゃう話です!
丸呑みメイン、触手プレイありとなっています。

※流血表現、欠損表現はありません。ソフト丸呑みです!

A story about a hapless mage who desperately tries to help fight but always loses, and ends being swallowed whole alongside her companion!
The emphasis of the work is "vore," with some tentacle play.

* There is no blood or gore here. It's all Soft Vore!

Table of contents:
pages 3-9, Getting Swallowed head-first by a Forest Monster.
pages 10-18, Walking naked through the forest and being swallowed whole by a plant monster.
pages 19-421, Fallen into a giant worm's trap.
pages 22-28, Just as I set out to help, I fall into a monster's trap!
pages 29-37, Helplessly Violated by Tentacles!
pages 38-60, The Worm's Feeding Grounds

I just realized that there's no "plant" tag, just "plant girl" or "plant boy". Kinda a weird oversight.
