Author's note:

Hey, it's been a while, I've just kind of been in the mood to write some Harry/Narcissa and I probably won't get the chance to write it in my daydream fic for a while so here it is, leave suggestions if you want, I can't promise I'll get to them but I'll try. Anyways, enjoy and please review!

An Overdue Thank You

Harry sat alone at the table in the dining room of the newly renovated Number Twelve, Grimmauld Place, grateful that the project was finally over. In the summer since he'd defeated Voldemort, Harry and the Weasleys had completely finished the cleaning projected and decorated the house to be a place Harry could spend his life and feel happy in. He had just had the Weasleys and some other friends over in somewhat of an opening dinner for the house, and finally he had some time to be alone and relax in his new house.

But first there was a letter he needed to write. He hadn't really had time to think about it since the battle, but he knew that he really owed Narcissa Malfoy a thank you, and he wasn't exactly sure what form it should take. He'd thought about it quite a bit, and he'd decided to start by sending her a letter inviting her over for dinner the next day to thank her, especially since she was a Black and this house was supposed to be for the Black family.

He finished the letter and took it to Hedwig to be delivered, and since it was late, he decided to go to bed for the night and wait for a response in the morning.

When he woke up the next morning, he discovered that Narcissa had already responded and Hedwig had left the letter on his night table. He opened it and began to read:

Dear Mr. Potter,

I would be glad to take you up on your invitation for dinner this evening, just so you are aware I will be dressing formally as I believe that is what the situation calls for. I will be there tonight at six exactly, I look forward to it.

Narcissa Malfoy

Harry smiled at set the letter back down. He had never really had any form of conversation with Narcissa, but he was glad she'd accepted his invite, as he really did want to thank her and the dinner was sure to be interesting.

When she arrived that night, she wore a dark green, tight, strapless dress that showed so much cleavage that Harry was sure the dress was held in place by magic. As she moved through the door, Harry couldn't help but imagine what it would be like to take her out of that dress. He re-focused his attention to her face but he could tell she was pleased with where his eyes had gone to.

"Good evening, Mr. Potter," she said coolly, "Thank you for inviting me here tonight."

"You can call me Harry, you can come sit down here," he indicated the spot across from him, "I'm glad you came." She came over and sat in front of him, crossing her arms and pushing her breasts even further into Harry's vision, allowing his eyes to be drawn to the Slytherin pendant between them.

"So, Harry, how did you want to start?" she asked casually. At that moment, Kreacher came through the door carrying platters laden with different meats, soups, and other dishes in what was one of the best-looking dinners Harry had ever seen.

"Thank you, Kreacher," Harry said kindly, and then turned back to Narcissa, "I think I should start by saying thank you, I wouldn't have survived in the forest without you lying for me, and I know it must've been terrifying, lying to him like that."

"There is no need for thanks," Narcissa replied dismissively, "We both no I did it to try protecting my son, and as much as I may somewhat loath to admit it, it is me who needs to thank you for knowing he was alive and telling me."

"Well, I don't know that there was really anything else I could've done in the situation, but I suppose we can stop dodging each other's thanks, so I would just like to know, is ther anything I could do to repay you for what you did?"

Narcissa opened her mouth to say no but then paused for a moment. "Well, this is a small request but I would appreciate it if you'd just show me around the house, I haven't been here in so long, I'd like to see what you've done with it."

Harry raised his eyebrows in suprise but nodded. "Of course, I'm quite proud of it, so I'd be happy to show you what it's like, although it'll be quite a bit different than you remember." They stood and Harry lead Narcissa out of the dining room. They moved up through the house, past where the old house elf heads used to be, past the new portraits of various magical views that had replaced the dark portraits that the house used to hold.

As they continued, Narcissa kept finding little ways to touch Harry. At one point, when they sat down in the drawing room for a moment, she had run her hand lightly over his thigh when they were talking. Later, she was holding something and dropped on Harry's lap, prompting her to reach over to grab it and Harry was sure she had felt his erection, and he thought she even let her fingers linger on it a moment longer than necessary.

Finally, they reached the master bedroom that was now Harry's, and Narcissa stopped abruptly in front of him, causing him to run into her. Harry caught her in his arms as she fell, and quickly became very aware of his hands on her bare skin. Narcissa turned in his arms and looked up at him, then wrapped her arms around his neck. "This room looks nice," the older woman purred huskily. She pressed her body against him, allowing Harry to feel her curves and her breasts pressed against his chest. She began to play with the hairs on the back of his neck and then licked her lips seductively.

"Narcissa..." Harry was shocked by the blonde woman's advances. Before he could continue, she had hopped up and wrapped her legs around his waist.

Their lips met in a hot kiss that made Narcissa dizzy with lust. Harry's tongue moved into her mouth firmly and she let out a loud moan as he moved his hand up her thigh and brushed against the front of her soaking wet knickers.

Harry carried her to the bed as they kissed and tossed her onto it easily, and was quickly on top of her again, kissing her and grending his erection against her. He moved his lips down her neck and sucked hard enough to leave marks, making her moans grow louder as she began to grind her hips up against him.

"Fuck, Harry, fuck me, please," she cried out as he continued sucking her neck torturously. He down to her breasts and began sucking hard on the skin there. Narcissa had never needed to be fucked this badly, and it kept getting worse as Harry moved her dress to suck and lick her nipples slowly sending waves of arousal between her legs.

"Please, Harry, just fuck me, I need your big cock," she screamed, her hands swiftly unbuckling his belt and unzipping his pants. She pushed them down and Harry slid his boxers of to reveal his large erection, "Just shove it in me!" Narcissa begged.

Harry settled between her legs and brushed his tip over her soaking wet pussy, making her whimper with desperation. Finally, he lined himself up with her entrance and slammed into her. She let out another loud scream of pleasure and arched her back, tgrusting her hips on his cock as he pounded into her.

"Fuck, make me cum, keep fucking me," she moaned and his thrusts somehow got even harder, sending Narcissa's body into the most intense orgasm she'd ever had. Her grip on him tightened as her body tensed, it was the best feeling she'd ever had in her life. She continued to scream in pleasure as he fucked her, and finally she felt him blast his hot cum into her and then collapse on top of her.

"That was a good way to thank me," she sighed, wrapping her arms around him. Their lips met for a deep, lingering kiss and her eyes fluttered shut and she dozed off to sleep under him.
