Uses rape-to-love/stockholm as its primary trope, but I give it a pass here as the story is so well constructed around it.
There's so much to like here outside of the BL aspects. Jin is the cutest seme I've ever seen and I don't think I would've ever considered a spider demon/spirit/thing as both cute and sexy as this. Also the octopus guy is funny too.
Adding this for the 1-shot in chapter 5 that was so very good.
Some of the hottest kissing smut I've seen.
The fetish on display here is so sexy.
Incest plus glory hole; what could be better. Some really nice ass shots in this one too. 1-shot at the end is not to my taste though (shota).
Main story ch1-4 is a really good age-gap coworkers story. Despite the cliche setup, this one feels a lot more grounded than those like it. Plus the characters and art are great.
Top-notch nipple-fetish smut art. Despite being only 2 ch, there's still enough story here to hang the smut on.
Urethra play fetish yay!
All of this author's one-shots are basically porn vignettes that are actually good -- smutty, great art, just enough plot to hang on the smut on. Some are more non-con than the others. This one is borderline, but I liked it the best.
