Oh, I know my way around power tools
And being a self-bondage enthusiast for a long time, I certainly found myself in a situation that called for an angle grinder more than once. And I use a bicycle as a primary means of transportation.
I see how that situation could evolve into a healthy BDSM relationship. But the guy blew his chance. I believe no relationship should start with yanking the key to restraints out of someone's hand. The moment he did that - he lost her trust pretty much forever. And then, sorry man, an angle grinder and cops
Anyway, the story is good, I just wish the girl would get her way in the end.
(I'm actually thinking about writing my own version of "self-bondage gone wrong" short story, but with a different angle, not beaten to death 15 years ago
)
