adultonly(http://www.pixiv.net/member_illust.php?id=11844141) has basically removed all his hardcore work from his page. I like his work, so I'm sharing what little I've been able to find.
No idea where the hell he posts his new shit (if he even does post explicit versions anywhere), so everything I'm posting is pretty old.

If he is Korean, the reason behind the removal may be explained by their policy on porn.
