@epa Not really drama this time. Yui is going through highschool entrance exams and they decide to not have sex until the exams are overso she can focus on studying, but as expected they both have a really hard time enduring that long. In the end it all works out fine.
Please upload the omake too. TIA. (Update: as the comments make it clear, most people can't read the Japanese instruction or even copy and retype a Japanese password, so please don't be a dick and share the omake if you can for the 99% of the world which does not read Japansee...)
As for authors half-boiled strategy "to prevent illegal reproduction of her books", seriously? We are on the pirate book sharing site. And how long until she removes the omake, her hdd dies without her having done the back-up and it's gone forever? Similar stuff has happened in the past. Sharing is caring (and preserving for posterity).
Anyway, the omake is here http://aquadrop.chu.jp/test.htm
But I also encourage you to spend $$ on the artist. I think she shares some links to buy her works at the omake page such as http://www.dmm.co.jp/dc/doujin/-/detail/=/cid=d_115262/mikamikami-001 but that site is actually blocked (censored) where I live so I can't verify. I don't think she has a Patreon
I don't think it is appropriate to upload the omake manga here, as the artist specifically claimed the omake manga is her strategy to prevent illegal reproduction of her books. You can directly access the omake manga with the password I posted above. The link to access is on p. 54.
Unfortunately, both I and IBfreehome do not have enough English proficiency to translate the series to English (enough to communicate and read though). I hope someone else could translate the series to English too.
Everything you need to access the Omake has been posted in the comments, try reading them and figuring it out, is not that difficult.
The omake are cute but also whatever. The real gold is the fantia exclusive chapters. Man I hope I can get to read Oiwai Sex at least once before dying.
