I'm not sure if anyone can help me, but...

I remember reading a manga online a while ago. It was about an after school club with just a single female member. During one of their meetings all of the boys appear to have been frozen in time, leaving the girl wondering what was happening. She then decided to take the opportunity to strip naked and show herself off to the time-frozen boys, only to discover that they were only pretending.

Does it ring any bells with anyone? Do you know what it's called?

research title
 

Does anyone know this serie? :)

2 more chapters from Mika ni harassment. This time Mika becomes an exhibitionist. Next one gonna be the last Mika chapters.

Last 2 chapters of Mika ni Harassment. Mika and another girl get on a weird situation, plus the remake of the kindergarten chapter from the old Mika manga. Next post gonna be the pdfs of the whole thing.

The 9 chapters of the new Mika ni Harassment. Plus some one-shots by the same author Suihei Kiki. Gotta give credits to the bas/e/d anonymous who uploaded this first.

There's a hentai site with the entire comic, however it's members only, so here are the relevant pics in a larger format for you

thank you :)
 

Haha thanks for that. Weirdly enough the story isn't what I had expected hehe but thank you for your response :)

Where did you find this?

I think it was here, but I don't really remember, why? Do you know the title?

I don't. I wish I did as I love this kind of gradual clothing loss. Reverse image search didn't help and a lot of manga artists drew like that in the 70s and 80s.
