Sam: He always loved to kiss your forehead, and sometimes nose. The very first time he kissed you was on the forehead. You didn't mind as long as he was yours. You'd kiss him back on the cheek, turning several shades of red.
Cas: Not even you know why Cas loves kissing your shoulders all the way up your neck. Sometimes he'd even kiss up your jawline.
Dean: He'd kiss you passionately on the lips, never forceful. Always full of love and caring. He'd move from your lips all the way down your neck to your collarbone.
Lucifer: He'd start on your lips slowly traveling down your neck then your collarbone. From there he would leave kisses all the way down your tummy (hehe I love the word tummy xD).
Adam: He'd kiss your cheek, pulling you into a never ending hug. He would then proceed to leave small pecks on your lips.
Gabriel: He would pull you into a passionate kiss. Lasting for what felt forever. When you pulled away he'd plant a big kiss on your nose.
(Hey everyone, should I do more of these? Just wondering. Thanks for reading!!)
