I am basically reading this in reverse order only because the recent uploads are in the front and there's no proper index that puts them in serialized order. but It looks like this is the rare story of what happens to Party B in an NTR story after they leave Party A for Party C.
I like page 56 with her heel dangling from being fucked. A little detail that makes it more realistic but also erotic. The principle is right, heels are attractive. And very few artists can draw out why.
