Interesting start you've got here. Sakaki and Haseo seem to be in character, and it's about time someone noticed that Sakaki was able to basically remotely stalk Haseo while he had the Serpent of Lore handy! XD

I don't know if I'd like to see things go in the direction you're promising (even if the setup for the plot wasn't completely obvious, you've already put non-con warnings in), but that's mostly because I don't think Sakaki's really interested in something like -that-. I figure him as the 'wanting Haseo as his minion-puppet-thing' type. He's like 10 offline, you know, I doubt he's gotten interested in having sex yet.

Aside from that, I like the fic and I'd be willing to read more of it. Even if you take it places that I'd rather not go.

Good job!

You have a lot of potential with this, I would like to see where it goes from here.

Its a prologue, and those are meant to be short, but it still makes me wonder, 'What is going on in Sakaki's head? What does he want with Haseo?'

I would be pleased if you could continue this. :D

very nice detail in your descriptions. could be a little longer, but it was good anyways
