>>43773367Honestly, from the Skarmory you posted, I assumed you were going for a blood-absorption/iron strengthening sort of obscure fetish. I read a pastbinned fic in like 2014 about a metallic creature essentially drawing blood with their partner as a form obtuse sexual encounter since the thing didn't posses genitals and because, blood having a high iron content, effectively translated to "part of you becoming part of me" kinda like how Zabuza's sword repairs itself when covered in blood. Pretty hot shit in retrospect and all very consensual and clean, relatively speaking.
