You roommate,Nathan,he just use brace on his teeth since he has one crooked tooth that always accidently bite his lips

You and him are quite close so you decided to tease him,you tell him he looks like darla from finding nemo,his face got red when you say that

He smirks a bit "yeah yeah,but i still can do this" he lean to you and fastly kiss your neck without a warning,you can feel his brace and lips on your neck,
