Kurt and Sebastian moved to New York together after high school. Their relationship was friendly enough, though still fraught with sarcasm, insults and endless witty banter. After living together for six months, the sexual tension between them became constantly present in the apartment, no matter how much Kurt attempted to deny it. Eventually he cast aside his pride and, for the first time, allowed himself to act on impulse.

Basically, sexy Kurtbastian shower time with a little backstory and some verbal foreplay, filled for a GKM prompt.

A one-shot for a GKM prompt. Kurt and Blaine are living together while Sebastian is visiting. Kurt wants to surprise Blaine, who is due home from work soon. He preps and situates himself on his hands and knees just inside the door, presenting himself. When the Blaine comes home, Sebastian is with him and they walk in only to find Kurt on display. Smut ensues.

SPOILERS. When Kurt and Blaine break up, they deal with it in different ways. Rated M for a few curses? I guess.

Written for this prompt on the Glee Kink Meme: In New York, Kurt keeps running into Sebastian. The tension is ridiculous as they try to keep things civil. Eventually it becomes too much and they agree to meet at a swanky hotel that Kurt picks out and Sebastian pays for and just fuck the sexual tension away over the course of a weekend. Too bad the weekend seems to get longer and longer as they become reluctant to return to their normal lives ignoring each other.
