Bijin Gym Tore Wa Gaman Dekinai (“The Beautiful Gym Trainer Can’t Bear With It”) [English], by Asano Yomichi
A young salaryman starts working out at a gym, and his personal fitness instructor happens to be a busty cutie (with thick eyebrows, woot!) with a huge fetish on the smell of men’s sweat. So, yeah ^^
The story is simple and pleasant, the art felt original and fresh, it was a nice read, thanks a lot to Nisor!
By the same artist, I also share Yuuwaku Beast.

A salaryman (even in H-universe Japan) foregoing the usual drinking party to instead go to the gym …

Notwithstanding, and saying this without any firm statistics, the overall health of the Japanese population just might benefit from more people doing such a thing.
Oh, and the story was nice, too. 👍
Dang, at first glance I thought it was rei.
almost thought this was an Eva doujin cause she has the Rei Ayanami haircut
Pretty sure that if there where more trainers like her, no man wouldnt stick with his training regiment…god knows i wouldnt skip, not even leg day!
Thanks for the share!
Damn, everything slides off of moisture-wicking fabric.
