hmmmm i think marie is kinda pathetic in bed and while at first she's pretty tame and vanilla at first she becomes really interested in bondage, maybe some sensory stuff too. shiver i think likes the power dynamic of making their gf edge with full body restraints, but it was a gradual process. i also think marie finally allows herself to let her guard down, so maybe she gives shiv her consent to give her mornin sex (when shes still asleep)
