Just some fun smut. Burt overhears Blaine and Kurt doing a certain activity. Enjoy. Rated M for a reason.

Burt knew he was early. He hadn't seen his son or his son's boyfriend in over three months. Was it wrong for a father to be eager. He took the closest spot in the parking lot and headed for the stairs. In the back of his head he could hear Kurt scolding him about his heart, so he made a turn for the elevator.

On the ride up, Burt checked his watch. He was a little over a half an hour early. Burt shrugged it off thinking that Blaine and Kurt were probably sitting around and would be fine with him being early.

He approached the boys apartment and gently rapped on the door.

When no one came to the door he tried the handle. Luckily, it was unlocked. Burt carefully closed the door behind him. He looked around the apartment. It looked relatively the same since his last visit. There were a few new rugs, a lamp, and a few pictures, but besides that it was like nothing had changed.

Burt was about to call out when he heard a noise. At first he couldn't tell what it was. He listened closer. A few seconds later he heard it again. Soon he realized it was his son.

"Ohhh." Kurt moaned.

At first Burt thought he was hurt but then he heard another voice come from the same direction, the bedroom.

"mmmm" the voice moaned.

Burt's eyes suddenly flew open. The second voice was Blaine. Wait, were they...?

The noises coming from the bedroom got louder.

"Oh, you feel so good. So fucking good."

"Please...oh yes!"

"Ohh!"

Burt wanted to leave but his mind and feet wouldn't connect. All he could do was stand by the door in horrified silence.

"Maybe they arn't doing...that. They could be...jumping on the mattress...trying to get the lumps out." Burt thought to himself, desperate to take his mind off the sounds.

"Right there!" Kurt screamed.

"See, he landed on a lump...oh who the fuck am I kidding..." Burt burred his face in his hands as he tried not to give in to the twisted images of what that boy was doing to his baby.

"Oh Blaine, i'm so close...so close." Kurt gasped.

There was a loud creak of a mattress and an unmistakeable sound of a headboard hitting the wall.

"Oh, oh, oh, oh," Kurt cried out with each thrust Blaine's hips gave him.

Burt was still in denial until he heard Blaine choke out two words.

"Gonna come..."

Their panting was so loud it could have been heard from downstairs. Blaine continued to ride into Kurt until they both couldn't take it and came loudly.

Burt wanted to lay down on the floor and die.

"When will your dad be here?" Burt heard Blaine pant.

"Any minute, We have to get dressed." Kurt mumbled.

There was some scurrying and suddenly Burt found the will to move. He quickly left the apartment, waited a minute, and then knocked.

"Coming!" He heard Kurt's sing-song voice call.

Burt shuddered at the word.

Just a short little smutty thing that popped into my head one night! Short and sweet! Hope you enjoyed. Please Review!
