A sweet reunion. [Incest, possibly n-con]

[Ptolemy]

Is anyone up for an ancient Greek themed incest story? It could be forced at first,  but could perhaps later turn in to true, but sexual love for each other. Perhaps, a boy who left for military service when he was rather young has just returned home after a lengthy military campaign (The Peloponnesian War, perhaps?) a few years after coming of age. He would either take his sister as his own, or his mother after coming back. It's a simple concept, and hopefully the fine details could be negotiated by PM through proper rapport. Sorry for the short post, but, really, two heads will be better than one if anybody is interested in the concept of an Ancient Greek-themed incest story.
