Hux takes Kylo to Snoke as instructed. When they arrive they're both shocked to see Snoke in person. He doesn't look anything like his hologram but is actually a devastatingly handsome human who looks to be in his early 40s. Hux is not best pleased about his lover spending time with this super powerful hot guy.

+ Possessive Kylux sex with Hux wanting to remind Kylo he belongs to him and not Snoke.
++ Snoke knows Hux and Kylo are sleeping together and is not happy Hux thinks he can touch his apprentice. He purposely messes with him by touching Kylo way more than necessary, whispering intimately into his ear, always talking about Kylo's loyalty to him and the bond they have that no one else could possibly understand. Kylo is loyal to Hux but is super turned on by Snoke and in awe of him.
+++ If it somehow ends in a threesome with Snoke and Hux dominating the hell out of Kylo that would be excellent.
