A highschool boy has to run errands for petty bullies because he is too weak, they challenge him to arm wrestling and every time they beat him he has to obey them again.
So, he goes to a gym. In which he faces the painful truth he’s simply too scrawny to build up mass.
That’s where the story would end if it were the real world. Fortunately, being an hentai world protagonist, he is recommended the special training regimen, in which a sexy female coach has sex with him between workouts to keep him motivated ¯\_(ツ)_/¯
Again, if it were the real world, it would make no final difference, he’d still be too weak to win those arm wrestling challenges, but, eh, good for him, right? ^___^
I won’t promise you god-tier drawings, I didn’t even recognize Ashiomi Masato’s style at first, but I still found it pleasant to read, good enough, let’s say? A note, though, I ran one of my routine retouchings on the images, grayscaling them and levelling them a bit, that also strongly reduced the archive’s total size, a nice bonus.
It’s been released by Slouch2, thank you!
