Asp.Net MVC and Redis - Single Session per userId -

i'm looking way allow 1 session per user. differently other cases, not want prevent user logging while session still active. behavior i'm looking "substitution", e.g.:

a user log's pca , right away logs pcb (or another/anonymous browser matter). logs onto pcb, whatever action performed on pca supposed treated "session expired"

how can achieve behavior?
ps: i'm using asp.net mvc 5 , redis cache session state store.
