@jimmy118

March is the third month. March 10th is 3-10 (and in Japanese, even the name of the month also involves the number 3 (Sangatsu / ３月 / 三月)).

2030 is gonna be a helluva decade for the oniichan

God, the theme of this doujin is so good. The non-sex days pages add so much flavour, insta-favorited. Too bad it didn't cover all of March then the transition to April.

Feeling rather blue balled since sex is interrupted every 2 pages, but my emotional boner is pretty satisfied. Cute couple of siblings

Is this a leap year reference?

Base +5

thay they omitted page 28 on purpose so that it would be 33 pages long.

Base +6, kersh7 +5, see-eff +8, Davyroo +6, Syerathe +13

mangadex has the missing page translated. someone less regarded than me can get it and fix this album

can't wait for the dojin to be translated as well

Ignoring months with those numbers, she's DTF on days 3, 6, 9, 12, 13, 15, 18, 21, 23, 24, 27, 30, and 31... assuming a month has 31 days.

So the brother is getting some action 11 days out of every month MINIMUM

Also @orangedew, if months and years count, then imagine if someone went by this and the year 3000 hit....

Base +9

pretty sure 2025 is divisible by 3, no need to wait until 3000

What was it she messed up? The drama?

Clicked on this expecting nothing and ended up liking it a lot. Hope the prequel to this one and the sequel gets translated too. Looks like the artist is still drawing more after this part but I don't get why the stuff before these pages wasn't translated before.

Fun one !
It feel like there is an actual chemistery betwwen thé two !

@Red 255

While true, the year 3000 marks the start of daily sex for their entire lives should anyone do the same thing then. Not just 1 year. And that's simply because every year has a 3 in it for the next 1000 years

Base +9

this one seems nice, the sister is hot and i like the sex intertwining with the rest, but i'm a bit worried since the last 2 pages the author started to skip days (and skip the sex like in march 3) , i really hope that doesn't become a habit, i mean, assuming there will be more

Base +9

Pretty fun one yeah
