TYPE.90 is a doujin and h-manga artist who is a member of the circles Daihon'ei and TEN YARD LINE. He used to be much more active back in 2011, and prior. According to his blog, he was at Comiket 87 with a release, and in the mean time has been producing small oneshots and commissions.
TYPE.90 has worked with other artists to create doujins as well, contributing his extremely unique artstyle.
His art typically includes a mix of very large breasted women, as well as petite women. There is also plentiful anal, large insertions, bulges, nakadashi, etc. His art can be very rough, but is overall consistent. His manga are typically all one story arc, rather than a collection of shorter stories or oneshots.
He has only one work on Fakku which is a shame because he has so many works: https://www.fakku.net/hentai/cattle-sister-english

The story is about a slutty older sister (another older sister character appears in the work) and a slutty older girlfriend, both of whom are depicted in the sample CG. I have known this author for a long time, and he is one of my favorite authors, as he draws relatively hardcore play (group play such as orgies, genital and anal expansion, double penetration, and bloated bellies).
This work also features hardcore play with bulging bellies, but since the characters are actively seeking erotic things, I don't think you can feel the dark atmosphere that is common in hardcore play. At first, it was creampie sex, but it became more and more extreme, with bloated bellies, masturbation with giant dildos and anal beads, fisting, and more, which is very erotic.
