Starting with this , i was searching for a Doushinji i couldn't remember the name but i have quite some hints about it.
There is this loli (pink hair if i remember) with some eating Issue , so much that he get into a group of older boys to eat something special, if i remember correctly she was blindfolded and had some taste of Brood and "juice" , later on (after the whole things , bukkake and all) she get along with one of the boys couse his juice was "tastier" and after Bj and they go all the way.
lets see if someone can get this
