When the boys realized not just about anyone is willing to swap freshly worn clothes with you just to get some laughs…
When I saw they'd swapped uniforms I was thinking along those same lines. I'm sure there's a
lot of middle school (and high school) boys who'd find putting on a girl's freshly worn uniform a thrill, not punishment, even ones not into cross-dressing.
Counter stuck at 0, doesn't even go up
You made a typo, it should be "Counter stuck at 0,
won't ever go up"
So the girls and boys swapped outfits. Were the four of them in their underwear together? How did they manage that trade?
I could see the girls forcing the boys to strip to their undies first, then make them turn their backs while they undressed and put on the boy's uniforms. That would even explain why they did a swap instead of just making the boys cross-dress: the only girl's clothing they had handy were their own uniforms and they weren't willing to let the boys see them in their undies.
Next chapter it will reveal Mahiro actually did piss herself before she made it to the bathroom
Nekotofu really missed an opportunity there, he could have had them really go out for a stroll and one of them slipped in a puddle in the hallway. All the readers would have known it meant Mahiro didn't make it to the bathroom in time. I'm kind of surprised they didn't do that to be honest.
You'd think Mahiro would have started going to the bathroom during every class break at this point, but Mahiro's clearly a slow learner.
It's a shame they didn't end up going for a walk around the school cross-dressing, it'd have been fun to see their reactions.
