Kurt and badboy!Blaine have been dating for a little over 8 months now and have tried everything. The New Directions don't know but Burt does.

"We should play truth o-" Tina was interrupted by the doorbell, "Who's that? I thought everyone was here."

"I'll get it!" Kurt cried and shoved Finn out of the way to get to door.

"Dude." Finn rubbed his head as he stared at the space where Kurt was.

"Kurt seems excited for whoever's at the door." Santana raised an eyebrow, "Let's go see who it is."

Santana smirked, stood up and walked out. She knew Brittany would follow her and the rest of the New Directions were too nosy for their own good so she wouldn't be alone for long.

"Well, they went up there in a hurry." Santana frowned as she watched Kurt and the stranger slam the door shut to Kurt's room.

"Burt?" Finn stood in front of the man as he entered the room, "Who's that?"

"That's Blaine he's Kurt's- Why is the door closed?"

"Why would the door need to be closed?"

"Same reason why you and Rachel have to close the door."

"Because we might have sex?" Finn frowned when Burt choked on his beer, "You okay?"

"I'm fine. And yes, that is the reason why they have to have the door closed."

"Excuse me, Sir." Mercedes smiled at the man, "Are you saying what I think you're saying?"

"If what you think I'm saying is that Kurt and Blaine have no self control, as soon as they're alone they start making out like crazy and they go at it like rabbits then yes. That is what I'm saying."

"Umm, I was actually thinking that this Blaine guy was Kurt's boyfriend." Mercedes rubbed the back of her neck awkwardly.

"Oh. Right. Yeah, they're dating." Burt glanced around awkwardly before noticing the closed door, "Why is that still closed!"

"What're we just standing around for?" Puck frowned at the teens once Burt had left to Kurt's room, "Let's go meet Hummel's new boy toy."

"Kurt Hummel!" Burt yelled as he saw his son and his boyfriend in the middle of a very heavy make out session on his bed.

"Dad!" Kurt shrieked embarrassedly before blushing even more when he noticed the New Directions behind his dad.

"Wanky."

"Kurt, what've I told you about this?"

"That I can't do it." Kurt rolled his eyes, trying to push Blaine further away from him.

"Well, then why do you still do it?"

"Because we might explode from all of the sexual chemistry if we don't. Do you want us to explode?" Blaine raised an eyebrow, "Do you?"

"No. I do not want you to explode. And I don't mind if you do it anywhere else but not under my roof!"

"Oh trust me." We do it anywhere else. We do it most places, actually."

"Blaine shut up." Kurt growled, still trying to hide his very obvious blush.

"Why? Would you rather me lie to your father? Okay. We haven't done it here. We haven't done it at Kurt's school. We haven't done it at my school. We haven't done it in the Breadstix toilets. We haven't done it in the kitchen upstairs. We haven't done it in the park. We haven't done it in Kurt's car. We haven't done it in-"

"Enough!" Burt slammed his fist down on Kurt's vanity mirror.

"See, Kurt?" Blaine turned to his wide eyed boyfriend, "Parents don't like to be lied to."

"We haven't done it in the Breadstix toilets." Kurt frowned.

"Kurt, I'm taking you out on a date to Breadstix in about an hour."

"Oh." Kurt's eyes darkened slightly before he shook his head and turned to his dad, "Sorry. He's a sex addict."

"Mm. I can see that." Burt watched as his son stood up off of the bed and Blaine's eyes immediately fell down to his waist... Or lower. Burt hoped it was just his waist, "But you seem quite addicted as well, son."

"I am not addicted!"

"I beg to differ." Blaine smiled innocently from his place on Kurt's bed.

"Right, Kurt. As a punishment I will be taking your phone off of you."

"What?" Kurt shrieked, "That's not fair!"

"Don't worry, babe. I'll keep you entertained." Blaine smirked up at his boyfriend who turned to glare at him.

"And you will not be allowed to go on this date with Blaine."

"Woah." Blaine suddenly shot up off the bed, "That's not happening. Sorry, man. But it's just not."

"I believe the I'm the one that decides whether Kurt goes or not."

"Nope." Blaine shook his head, "Y'see, Daddy Hummel. My sexy boyfriend here is 18 so he can do whatever he like. Besides, we've snuck out before, we can do it again."

"Would you like me to tell your parents of this?"

"They don't care." Blaine shrugged, "They know I'm very sexually active but I think they gave up on me a while ago."

"Whatever!" Burt threw his hands in the air, "I give up too, then."

"That was easier than I though." Blaine grinned as his wrapped his arms around Kurt's waist.

"You're crazy." Kurt laughed as he let his head rest on Blaine's shoulder.

"Crazy about you." Blaine whispered back.

"Ahem." Mercedes raised an eyebrow.

"Oh! Hey 'Cedes. I've been meaning to tell you." Kurt smiled, "This is my boyfriend, Blaine."

"Mm, so I've gathered."

"Lady face." Santana smiled, "I'm very jealous of you but also strangely proud. You've grown up. And also you better take care of your man because I'll be up on that as soon as you let him go."

Kurt glared at the Latina as she raked her eyes over Blaine's body before sauntering away, swaying her hips purposefully.

"Mine." Kurt whispered as he drew Blaine in for a very passionate kiss.
