[1) This kiss probably tastes a lot like blood, considering all the punching leading up to this. Which is possibly a plus, considering the people involved. 2) They're probably both quite accomplished kissers (one hell of a kisser, plural, if you will). 3) Sebastian moves one hand to cup Lucifer's face. Precisely because they've been fighting, Lucifer is injured and Sebastian wants it to hurt.]
