Sorry if the picture's a bit blurry, my camera has bad focus on how old it is.
(And yes, Three some- Cross x Nightmare x Dream)

Creamare Headcannon: Sometimes Cross and Dream would find Nightmare late at night asleep on his desk sleeping cutely and snoring lightly.

So the two would always have to set everything up (blankets, pillows. Themselves) They're quite messy sleepers (mostly Cross), and withour waking Nightmare ofcourse, he's a bit of a light sleeper, so he actually wakes up during it, he'll never admit out loud but he enjoys it.

And in the morning, since Nightmare's always the one to get dressed, he would cook dinner to get the boys down (usually pancakes/waffles, which is also one of the reasons why they finish it in a week or two).

And then the two would fall down the stairs in rush, also falling on eachother...it's amazing how they're all still alive.
