Octavia: She cuddles up to you, she is usually the little spoon. She sometimes faces you and wraps her arms around your waist, under your shirt (if you have one on).
Raven: Mostly the big spoon, she holds you really close to her a kisses you cheek and neck whilst cudddling. She likes to pull you ontop of her sometimes and you sometimes sleep with your head resting on her chest.
Lexa: Cuddles you, you usually both face each other but she tries to pull you ontop of her sometimes.
Clarke: She likes to cuddle, not always as she gets sweaty. You like to whisper sweet nothings into her ear as she drifts of to sleep.
Luna: Rests her head on your shoulder and has one of her arms wrapped around you waist.
