Only my brother, aside from a brother by blood he also is a brother in arms when it comes to hentai stuff. Heck, it's because of his evil influence that I get to know hentai in the first place, CURSE HIIIMM!
... On the other hand, not like I regret knowing it. Although I do feel a bit weird seeing hentai these days. Pshaw, my morality is killing me again...
