Staring at someone so lustfully that you might as well be having sex with them.

Eye sex can only happen if your partner has lost at least one eye. You insert the penis into her/his empty eye hole and fuck it. You can also do with a healthy person with 2 eyes, but this would be very painful and could result in severe eye damage, so it is not recommended.

how merlin and arthur look at each other

eye contact that withstands a time period longer than the casual encounter. eye contact that signifies: come hither.

The kind of relationships between two same-sex persons (occasionally happens in TV-shows) that gives to girls all over the world a gulp of desire and this sweet madness every time their beloved characters do this. Sometimes fandom can be born just from the eye-sex.
