My Secret Nighttime Pleasure

I've been keeping something from my wife for years. Ever since I started working nights, these long hours have given me a chance to explore a side of myself that's not exactly... vanilla. Whenever she's asleep, I let out all the pent-up tension by trying different restraints and exploring what it means to be truly bound and helpless in more than just my job. It sounds silly when I say it out loud, but these moments are cathartic. Just needed to confess this before it becomes a problem.
