So is the child that she gave birth to a child born from her brother's sperm?

No, In page 11 the little brother was saying that she left him for another man. So I think it's her husband baby, but I don't know about the next one. HA HA HA HA. Enjoy!

I did, but it's taking too much time, too much resources. Me and @shinangels are trying out this tank first.

hmm. I must of miss a page or something. When I proofread it there was no sign of the kid being his, but after rereading it there it is. BABY WAS HIS.

Any plans on doing the rest?

The baby's father was the brother. The last page indicates that the story of her living with another guy (who knocked her up) was made up in order to be less taboo than what actually happened. Besides that, it's hinted elsewhere in the story, such as on page 16 .

... That's... kind of the point in it being a lie, isn't it? That somebody would believe it to be the truth? How do we go by what the brother says when he apparently never heard about it being a lie? He says that on page 11, but twice she tells him after that that the first one was his too.

I get that you're the uploader and likely had a hand in the translation, but what are you doing there, huh...

Less of a taboo than the truth? Given that last panel, I'm pretty sure her father knocked her up when she was a little kid, and the kid she gave birth to was the brother here.

"Do you want to try drinking some too?"

If only you could have seen my reaction.
By far this isn't the weirdest thing I've ever seen,
but the fact that she asked that so casually just made me pause for a moment.
The fucking things doujin characters find and do without a second thought, man...

Been waiting for this one. @Alex68785, we would love to but just trying to get one tank translated is already draining all our resources. Anybody that enjoys @Tkhang releases please look at & contribute to his bounties so we can do more faster. The more people that help with the contribution the more releases we can make.^_^

You know that feeling you get when something rather surreal has just occurred? Yep, this is one of those h-mangas that causes a temporary mental train wreck of 'WAT?'
