They never made it to the bed.
Klaus deemed it too boring and vanilla. And if there is one thing Klaus is not, then it’s vanilla. He prefers the floor, right in the middle of the parlor, so he can see their bodies in the mirror nearby.
Stefan thinks the bed is too inconvineant.. Perfect when there are two people, but not really feasible for three. He’s a man of space, and surprisingly the most random of places. He personally prefers the stairs. Says, the difference in levels is great to bend her over, and he loves the carpet burns he rubs into their bodies.
Caroline would quite frankly prefer the bed. Maybe in an attempt to gain some normalcy in their otherwise ridiculously abnormal life. She looses 2 against 1, and has to settle with the floor of the kitchen or parlor and the stairs to see her two men worship her.
But really, as long as she ends up in between them every night, it doesn’t really matter.
