Read up to Chapter 6 and so far this is just Softcore porn. "Regular Smut" tends to have quite a bit of substance before more sex but so far this is 1-3 pages of "substance" per chapter. Why not just make a H-Manga at this point?
@criver You're not wrong to call him a Gary Stu, but at least his powers have clear limits, he also uses his brain a little, and this has the smut tag, so yeah.
