NSFW for Deceit:

-Deceit's scales are really sensitive and when he has them spread out all over his body, it is easy to drive the man NUTS.

-One word.... Hemipenis! Since he's part snake, he has the appearances of a snake so he has two penises like a snake! (Which lots of you guys apparently have a headcanon for too... And that's something I can support!!!)

-He can switch between bottom and top, depending on if he's in his snake mating season(Hush, I'm going into the whole 'mostly snake' headcanon I have so there is a lot of things about his snake parts. P.S. don't call it snake parts)

-He loves teasing his partner no matter where he is. It could be during a movie or when they're out walking around.
