Hey it’s a valid question, I getcha >;} I’ve thought about it, too!

[^X a piece of my commissioned art drawn by the awesomeness that is @riwox, and there is a panel in it w/ oral action, but it’s just licking.]

Look at this comic that @remarried did, too, btw, along these lines, which I can’t bear to chop even a piece out of bc it has to be seen in FULL to be enjoyed!

IDK about other vampires but as far as VC goes, vampire dicks don’t get erect (there is alot of debate about this)(and I love writing/reading fanfic and seeing fanart in which their dicks DO work!)(but in canon, from my reading, I would say that they do not) so it’s kind of a moot point. But I do think they would still involve it in intimacy if they wanted to. See this post by @amadeo-child-of-the-renaissance w/ comments from @gairid. #Your headcanon may vary on this.

IN CANON: I don’t think that either vampire/vampire or vampire/mortal blowjobs are addressed in canon. I believe that anything that can be bitten can be an erogenous zone, and would enjoy being bitten anywhere, and they could bite mortal’s boners. Now I have this image of a dick just deflating on being drained of blood lol… 

How is there very much space in the mouth with those fangs there, tho? Especially if you buy that they may have other sharpened teeth than just the canines. Can they even take a dick in their mouths w/o cutting it? It’s fun to read in fanfic, but would there really be enough space for it? I’m not sure!

I would think that vampires would be limited in their blowjob abilities, unless the vampire’s mouth is big and/or the dick in question is relatively smaller XD

TL;DR: I do think vampires have to resist the urge to suck all the blood out of a dick during a blowjob, if they want that dick to keep working. 

@thebibliosphere, help me out?
