Worry not anon!! It was half of her fault to begin with xD
(Y'know that floaty feeling you get when you lose blood but imagine that amplified a bit due to Ingo's vampire toxins that would numb the pain from the bite mixing in. Kinda like she got high for a mere moment.)
Though, of course it would prove fatal if Ingo, being the good bf he is, realized too late, but managed to notice Elesa was quiet for way too long. (Plus he always tells Elesa before any feeding starts, is for her to either tap or push him away if he gets too carried away, thing is she gets too carried away during it lol)
But Ingo is there for immediate resucitation (is that the word?) and a good reprimanding! So alls well and good
This fanfic that is based on that artwork adds more to it <3;
