Alright, I'm just gunna lay out my implicit bias as a mega muscle fetishist right here, so I'll just tell you straight-up, this manga is fucking great, it takes a fairly niche fetish and runs with it.
Story is pretty stock, but as they say "Nothing new under the sun" it's more the circumstances of Mr Macho himself.
Yes, the guy's proportions are really weird, even by my standards (Hi, I'm dotty and I draw women who look like walking flesh pumpkins) but honestly, if you view it more from the perspective of just comedy, it's really a non-issue. (Also it's actually an extreme way to not
limit poses with too much muscle getting in the way)
It really sucks that it stopped getting translated though, I hope someone continues on with it. (=u=)~b
