Club Joi. The Legacy, #1

Celebrating his 34th birthday, Simon receives an impossible gift from his favorite uncle, Paul - an archaeologist currently on dig in Egypt. Coming from a time long ago, and possibly not of this world, the bracelet of Sutekh - so named after the God of chaos and trickery, endows it's wearer with the remarkable gift of transformation. Sworn to secrecy in a language he and his uncle invented, Simon never the less gives in to temptation and uses his new gift to pursue a life of kink without anyone else, his wife included, being any the wiser.
But his motives are not all selfish as he also uses it to aid those in need.
