So, this is for this prompt on Glee-Angst-Meme (don't read if you don't want to know the story...)

One night Burt begs Carole to have anal sex. She agrees. Burt has an incredible time. The next day Carole complains of how sore she is and that she didn't really like it even though Burt went gently. Carole's a tough lady (she gave birth to a 10 lb. baby Finn! or something like that) so Burt FREAKS THE FUCK OUT when he thinks about his little Kurt having to put up with some large pushy evil horny man pressuring his baby boy into taking that into...Burt can't even complete the thought.
Extra super bonus if he wants to bring it up with Kurt but doesn't want to break down when he tells him about how bad it could go when some large pushy evil horny man tries to put his...Burt can't even complete the thought. He talks to Kurt anyway.

If there is any mistake/strange construction, just tell me I will try to correct it as best as I can.

Pairing: Burt/Kurt; Carole/Kurt and probably Kurt/Blaine at some point

Rating: M, of course...

Disclaimer: Not at me...

Summary

One day, Kurt has told his father to educate himself. And he did...with pamphlets... But a few months later, as he had totally forgot about it, Burt takes the next step in his education...

The Burt Hummel's sex education

There is one thing in life that every man need to never failed at been happy: imaginativeness. The kind wasn't really important, but change in the daily routine was. Life wasn't supposed to be dreary; life was supposed to be filled with surprises...

Burt Hummel had never shown any interest in fantasy. Not until THIS day. His life was quiet satisfying and he had enough to deal with. So, there was no sparkle in his daily life and not even more in his sex life. Everything was as platonic as it was supposed to be for a man of forty or so. He was taking things as they came to him and never pushed anything. The only exception was about his son, Kurt. His son that was so different that he could barely understand him. But even if he has wished that he was straight- a fact that meant less harm for him- Burt had never stopped to fight for giving him the best life he could have. For give him a lot of possibilities. He has accepted all his fantasies; has never complained about all sparkles he had found himself covert with a hundred of times, about all hours he had passed watching musical and romance or about all this time where Kurt had used him like his own living doll. Because he loves him, no matter whom he was, and that he has promised to his mother that he would take care of him, no matter what happen.

But everything had changed that day. The one where Burt had to give the sex talk to his son- he would never be able to thank enough that kid, Blaine, to have pushed him to do so, even if it was the most awkward moment of his life. For the first time, Burt has seen that flash of fantasy fire up in him. Those pamphlets he had given to his son described a mechanic that he wasn't familiar with and that he couldn't understand.

*Why on earth people has interest for sex anal?"

Of course, Burt was aware that it was the only way for two boys in love with each other to go through the entire sex thing, but where was the pleasure? He could only figure pain in those relations. Even if he told Kurt that sex should be used only like a way to connect to your love, feeling great was also really important. At least, it was for him.

A few days passed and the thought was still really present in his mind. More than once, he found himself about to search the information on the Internet, but each time he had just back off. He was too scared of which pictures he would find.

Three weeks passed before he took the matter in hand. There was only a way to subdue the curious fire in his stomach...

-Carol?

She frowned as her fingers dig harder in the man shoulders. Something was wrong. Burt's voice was insecure. She could almost hear his anxiety. More, it wasn't Burt habit to stop a kiss. Not a kiss that was given as they were nude in their bed, on the road of a great feeling...

-What's wrong, Burt? She asked softly, not wanting to push him.

He avoided her eyes for a few seconds before crash his lips on hers. The kiss wasn't long, but intense. As they went apart, he bit his tongue and said:

-I know we have never done anything conventional before and I'll understand if you don't want to try anything else. But there is a thing that I've in mind since a while... And I wonder how it feels, wonder in which way it can feels good. I want you to try with me if you are okay.

She could say how nervous he was. He shifted a little on top of her and bowed his head in the crook of her neck, trying once again to avoid her gaze. She softly cupped his check not understanding what he was talking about. He looked up at her.

-What do you want to do Burt?

-Anal.

The words were barely spoken, mostly whisper. She tensed a little. In all kinks she known about, that wasn't the one she would had choose first. Burt captured her movement.

-We don't have to, he said quickly. I'm sorry, it's a stupid idea...

He was about to pulling off of her when she took his wrist and pressed her other hand in his lower back.

-Stay, it's okay, she said, shaking a little. You are right. We haven,t do anything non-conventional yet, it's about time to try. And anal seems a good way to begin. Just...

She bit her lips then looked up at him.

-Go slow, okay?

He nodded, kissing her once more. As he did so, he realized that she didn't knew how badly he wanted it. He didn't knew it himself until he has asked for it. It felt like if it was the more exciting thing in the world.

When he let her lips, Burt winked at her before making his way down to prepare her as the pamphlets have explained to...
