Every time, without fail when you kissed Peter his lips always tasted like red licorice (he blushed the color of red licorice when you told him he really does tastes as sweet as he acts) and that’s the way you found out he was Spider-Man too.
After he’d saved you and swung you into a safe place, he’d seemed so grateful you were alright (you didn’t understand why) and he kissed you, he was too scared of losing you to not at that moment, he had to kiss you, to make sure you were with him and safe. The whole ‘kiss your hero’ scene. And as soon as his lips met yours you knew that flavor, you knew those soft lips could only ever be your Peter Parker

After he pulled away you whispered ‘Peter’ quietly, still surprised that Peter, your shy nerdy boyfriend, was Spider-Man. To which Peter, or Spider-Man at the moment, started frantically denying it and waving his hands around ‘who was this ‘Peter’? and ‘he didn’t know any Peters’. The familiar hands flaying and high pitched lying voice of Peter confirmed your suspicions, you scoffed, tugging his mask the rest of the way off and pulled him into a much longer kiss.
