Cute: Your story begins with loyalty beyond any reason or expectation. In a sleeper car in a train there is a well-dressed man in a position of power who has an attitude problem. The protagonist experiences things like chocolate with raspberry sauce and tacos. It finally ends with an intense stare. (Clearly this is Sanzo and Goku, version 2.0)

"I hate you," the man said.

"You always say that," the younger man replied, undeterred from his taco consumption. "I love trains. They're so great! I mean -- look at how tiny our bathroom is! How did they even manage to get a toilet in there?"

The man glared at him as he loosened his tie, took off his cuff links, and rolled up his sleeves.

"I should leave you behind at the next stop. You're never going to stop talking."

"Nope! Unless -- hey, wait, they have chocolate sundaes! Rock!"

The man whapped him on the head. "Why did I ever bother to take you along?"

The younger man grinned after swallowing the last giant bite of taco. "Because I give great blowjobs?"

He reached for the man, greasy fingers leaving stains on the man's crisp Egyptian cotton shirt.

"Goddamnit, be more -- aaah! God, yes."

Later:

The man stared at his very rumpled traveling companion.

"Why do you put up with me?"

The younger man grinned and kissed him on the nose. "Because you feed me, duh."
