So because some parts of my memory are pretty vague I’ll try to say as much of description as I can recall.
There was a weird tree theme where group of guys (seems like maybe merchants of some kind) were using many types of monster girls/fantasy races to let the tree grow some seeds with their bodies? Of course they were fucked before the tree thing…vague, i know.
What I remember well was that, sort of a, protagonist was the youngest boy amongst the guys. There was also the older guy he was explaining to him how the whole cycle was going.
From fantasy races there were two(?) Elf girls who nobody wanted to fuck by which young one was confused about. There was explanation by older guy to that question but can’t remember. Ultimately young one fucked them of course.
The end is just the tree thing, sort of a sacrifice to the tree now that i think about it.
