I have an extreme thing for comfort sex.
I have an extreme thing for for sex with someone whose station is supposed to be "beneath" you in a social ladder, like you being out of their league, etc.
I also have an extreme thing for brother/sister incest, so bonus if that can be implied somehow or worked in. Personally I have a headcanon that Narfi and Reyda were having trysts.
Also I like his sideburns.

Would prefer if DB was not an orc.
