If there's a better place to ask about this, please let me know. Also, excuse the tense shifts. I'm tired as hell and trying to remember details while typing proper English is somewhat difficult.
First doujinshi is about a trio of adventurer girls who walk into a rapey sort of town, first two take the dicks for younger/less experienced girl, who hides under a bed. Pretty sure it was fully colored.
Second is a more romantic/sappy story about a lolicon hunter/goddess who is legendary on the internet. Her victims are revealed to be sent to a different world where they become lolis. She gets super (and excusively anally) violated by one of her intended victims after she brings him to her world. Violation included lots of video-recording/watching, exhibition, and toy usage. There was some vaginal seal-removing and life-pledging towards the end. She loses her god-powers because of the seal, and ends up living with her would-be victim. Story begins similarly to how it ends, and isn't colored.
