[Locked] What is this Manga called?

Hello everyone, I am new to the forum. But I love Fakku!
Anyways, there was a manga I was reading earlier here on Fakku!
but I cant seem to find it again! >_<
It was about a Boy, sleeping with his sister. They were in bed, and outside they heard their parents walking by as they were doing it xD.

Anyways, It would be very appreciated if one of you guys could tell me the name or perhaps link me back to the manga! thanks a lot!

cheers

Request forum is

<----- that'a way

Sorry, I didnt see this as request as this manga is already uploaded on fakku. My mistake!

Mod Note: Since the thread starter has already created an identical topic in the requests section, I will be locking this particular one.

Sorry for the inconvenience caused.
