Anyone know of a hentai doujinshi/oneshot/whatever where a brother and sister (ages about 9 and 12 respectively) ride the train and there's only this one guy in a suit sitting across from them so the sister decides to fuck her brother to tease him. I don't believe the guy ever joins in on the fun. Anyways, I've been looking for it for ages since I remembered reading it on exhentai a year or so ago.

Oh, and I can't access exhentai anymore, so please post the name instead of a link. Thanks.
The name of the doujin you're looking for is called "Siblings sure are great"

Yeah, that's it. Thanks a bunch.
