(If you wanna do this for me too, you can but y'all don't have to!)
(Concept- Oc has fangs/sharp canines/sharp teeth. Remus finds out after teasing them about not opening their mouth a lot or eating in front of him. Fluffiness follows with some Remus being a pervert and Remus like.)

Scenario-
You have very sharp teeth/fangs, you are quite self-conscious about them so you don't give open wide smiles or eat in front of others. Remus, being the nosey àsshole he is, was dying to know why and would bug the hell out of you to know. But he was never told, making him frustrated but more determined. Remus tried to get you to laugh a lot, smile a lot, or even just catch you off guard. But nothing worked, it seemed that you were ready for anything. So he was left with just teasing his you about it, just wanting to annoy you at this point. He came up with all kinds of comments and they were REALLY starting to annoy you. "Hey (Oc)! Are your teeth that fûcked up that you don't like people seeing?" "Hey (Oc), do you get so much Dîck in your mouth that your jaw just hurts all the time?" "Hey (Oc) you look better if you smiled! Unless your teeth ugly then don't even show me!" You were tired of it, you were so close to just showing him even if it scared Remus. Maybe scaring him would get him to stop or maybe it'd just cause him to be very wary of you and keep him away... You really didn't want that though... "Hey (Oc)! Ar-" 'Fûck it!' You thought before turning to Remus and snarling at him, showing off your fangs which made Remus stop talking. "Happy?" You asked as you crossed your arms, scowling to show off your fangs still. "Holy Shît... Oh my god, bite me~" Remus purred softly as he stared at your teeth in awe and possible arousal. You blushed brightly as your scowl fell. "W-what?" "Bite me~ Oh god... That is so hot~" This caused you to blush more and stare at him. "T-that is NOT the reaction I expected..." Remus smiled slightly as he stood in front of you. "Can I see them again?~" You looked away slightly but gave him a slight smile. Remus smiled more as he eagerly grabbed your chin and made you look at him. "That is so hot~ No wonder you don't show these... You'd be fûckng irresistible!~ And they're terrifying! You could easily bite someone's hand off!" Remus stated in awe as he stared at your fangs. This made you smile widely, happy at all the praise about your fangs. Continue...
