Ara Ara - teaching him how to lift - kemuri haku

Guess who this kid grew up to become

Okay, this actually makes me interested in seeing a potential chapter, maybe even a multi-part story, for "How Heavy Are the Dumbbells You Lift?" where a young boy comes into the gym wanting to become buff and manly, and the girls help him out without any ulterior motives, but in their efforts to teach him how to work out properly, they end up showing off their hot, sweaty bodies to him, making the boy feel uncomfortable throughout the whole thing.
Then by the end of it his work pays off and when he next goes to school all the girls his age fawn over him, but all the boy can think about are all the older girls that did their best to help him get to that point.
