[This story was the official winner of my September 2018 Story Commission Poll on my Patreon Page. This prompt was suggested by Moonlight Tumble (with some slight suggestion by myself~), and is a NSFW story that contains strong themes of cuckolding, chastity, degradation, pet-play, small penis humiliation, M/M oral, voyeurism, infedelity, unprotected sex, and possible impregnation. Reader Discretion is advised.

Also, this story is shamelessly inspired by the cover page originally made by meggchan. Please give support to the artist for their fantastic work.]

It's been nearly a year since Sombra, the former Tyrranical ruler of the Crystal Empire, had been unfrozen and given the chance to redeem himself like other foes of the past. Even though his probation hadn't been easy (especially while living in the Crystal Empire under house arrest), the Ex-King was able to adjust to living in the castle as a "guest" as opposed to a Dictator. Fortunately, it seemed that Princess Cadance and Shining Armor were willing to accomodate him during his reformation, even if the rest of the city was not.

But as time went on, Sombra was able to notice the slight oddities the couple carried while around him. While he wanted to assume their behavior was due to his past, the truth grew more unusual as he received various books on taboo subjects, as well as suggestive eyes from both of the ponies. And on one particular night, after receiving a letter from the Prince himself for his presence, Sombra was more than willing to learn the truth as he's invited up to their bedroom in secret...
