In my spare time, I write fanfiction and lead a cult of cock worshippers on the Internet. It's not the usual kind of hobby for a 40ish "domestic engineer" but we live in a modern world and I like fucking with people's expectations.


  1. I’m presenting my bachelor’s thesis tomorrow morning and my head is like a book bag that someone tried to fit a library into. Thank you so much for your awesomely timed and wonderful distraction 🙂 maybe I’ll actually get some sleep tonight after some *nice* reading for a change!

  2. Oh wow….…..oh wow, just wow. I don’t usually leave reviews (I think I’ve only done so once before when you had been heckled by an idiot and I wanted to show support ) Mostly because English is not my native tongue and I always have a hard time finding the right words. But this time it was easy. WOW!!!!

  3. Just binge read this and I loved it!! I sincerly wish that this was how endgame had went instead!

    Everything you write is gold and I have read everything you have written at least once. Keep up the amazing work!

  4. WoW I Love this story, the whole story is incredible, and I hope there is a sequel, write when you can, thank you very much for writing and sharing it you are the best xD
