Lilith throne I don't recall it having any many (if any) pics its been a long time since Ive played
Degrees of Lewdity is also a decent one, once again no pics and its very difficult as everything tries and will rape you
EroToho is also a good one, no pics but its challenging and fun
Monster Girl Farmer - not exactly like the others, put alot of pictures and its text based aswell
Im sure ive played more but if youre looking for text based rpgs start with coc2/TiTs
