"Ugh, the blasted demon!" Sherlock yelled, growling.

"I told you, it's not a demon."

"Course not, it's not even alive. Damned thing won't even work!"

John laughed, getting comfortable in his chair. He looked over to the floor where Sherlock was.

"WHY?" Sherlock yelled in frustration.

"Honey, it's a Rubik's cube, it's not going to solve itself." John giggled.

Sherlock threw the cube on the ground, "Sod this!"

John stood up and walked to Sherlock, sitting down in front of him. He cupped Sherlock's cheeks, kissing him softly.

"You try and solve it then." Sherlock picked it up and gave it to John.

"Alright." John took it, turning around. He sort of went into a laying position, resting the back of his head against Sherlock's chest. He started messing with the cube, and after about two minutes he solved it.

"Unbelievable!" Sherlock gasped.

John kissed his neck and cuddled up with him. "Yeah, I know, I'm amazing, aren't I?"

Sherlock hugged John. "I solved half of it for you."

"No you didn't."

"Shut up."
