Mm'kay so I know there's already a ton of Vampire!Peter stuff out there but like...
Peter would be The Worst Vampire?? Especially if you're thinking CW/HC/IW era Spiderman. Can you imagine trying to tell that tiny little bean boy he has to drink people juice? Can you? Look me in the eyes and tell me he would fall to his knees in anguish at the mere thought.
Tony has no fucking clue what to do and oh god Peter please get off the ceiling that's more disturbing than I can put words to and rallying the Avengers and half of SHIELD HQ for a blood donation drive and Peter resolutely insists on thanking each and every one of them personally.
Steve and Bucky restore blood faster than anyone else and at least once a week Tony has to toss out a the kid's asking for a snack as he passes them for the coffee machine, or like the time Steve is reading in the common room and Tony watches the kid dithering behind him for a full twenty minutes before he sighs and says Steve, it's your turn to feed the baby.
Peter accidentally popping fang all the time and he can't talk properly around them it's just all slurred and lispy and really, Clint is trying to stop laughing but please say quantum-reflectory differential again oh my god. Half the photos on Tony's new photo wall have the kid flashing his new set of gnashers.
