Hmmm.......almost seemed like a bdsm-type relationship after looking over the entire thing, the masked dom, the (totally) submissive participant, then being tied up and tormented, the happy parting at the end from both of them....... not that I'm sure but it seemed like the whole thing was consensual and pre-arranged the way it played out.
And yeah, I agree with annie69, the story could've used some butt-sex to make it even better :D
Damned good stuff still though, thanks a lot for sharing :)
