Deans in his car driving down 17-74 in Todd Mission Tx one cold night. Hes all alone then Cas appears in the back seat and says "lets stop and get a room". So they stop at this nice hotel and Cas pays for a room with a king sized bed at flies them up. They'er in the nice hotel room and Dean rips his shirt off and shoves Cas onto the bed and climbs on top and then kisses him deeply.
