8 XXX : doujinshi

Well that was cute.
Big thanks and shout-out to /u/crazy4ever for [helping me find this doujinshi](https://www.reddit.com/r/doujinshi/comments/3zma5e/request_doujin_where_older_brother_is_a_wingman/cyorp8d).
Why do they always tell the girl she'll catch a cold? Is that common in Japan? Don't they heat their houses or something? I've literally never heard anyone say that to someone in real life. It's so strange, and I see it in almost every manga.
that was cute and all but that girl went through a huge transformation in the beginning
My body will become weird!
