Under the mistletoe?
Leo- this dork would get so embarrassed and so conflicted. Because while he really wants to kiss his crush, he doesn't want to do something that they aren't comfortable with. So his crush will have to be the one to kiss him and afterwards he will be a stuttering mess because more than likely, that would be his first kiss.
Raph- this boy will become as red as his mask oh my goodness. He will deny deny deny that he wants to kiss his crush, while in the inside he will be begging to the gods that they get to kiss. Eventually he will yell out something amount of the lines of "fine! If you really want to me that bad I'll kiss you" maybe less rude, but something like that. After they kiss he will be blushing still, but bashfully.
Donnie- this nerd will be so casual and nervous about this at the same time. He'll chuckle nervously and say a really cheesy line. For this kiss both him and his crush lean in and after they kiss he will be on cloud nine and will most likely be in a blissful daze for the rest of the day.
Mikey- he will be blushing but happy, he'll verbally ask his crush if they're okay with it and if they says yes, he's gonna kiss them no questions asked. And he will be smiling for the rest of the day.
