Captured School Boys [Commission] (Pixiv Fanbox)

When a group of school boys were told about a secret underground hideout in the nearby forest, their first reaction was to check it out as soon as possible! And because it was their teacher that told them about it, they knew it must be true, and that they would be kept safe. Unfortunately for them, this was far from the truth. I would normally say they're going to learn the hard way to not be so trusting, but it doesn't matter because they will never again get the chance to use this life lesson.
