Junk Land is a full tank made of 10 chapters and of those 10, 8 are independent chapters so there's quite a collection of material in there. This h-book has a range of stories for varied tastes. There’s some vanilla, some torture, some BDSM with black-mailing, anal, group sex, voyeurism, Yuri and even shota. Before you say meh!! I think I pass because it has torture and BDSM chapters, fear not those are for pure comedy and very light. I can’t say any more without spoiling the story.
The only drawback that I could find for this manga is that if you are not paying attention to the transition in between chapters you may get confused because some of the heroines look the same however if you pay attention to the cover art and first pages they let you know that each stories have different heroines except chapter 1&2 (She is the same).
Aside for some of the girl looking the same the enjoyment that you get from reading and seeing some of the situations mostly of the awkwardness between partners and the sex scene you get a few laughs…
In conclusion. If you like tomboyish girls plus girls with megane like me, give it a try! Also you might want to check out the hentai adaptation of this if you liked this book.
