Chapter 8

Christmas morning dawned bright and cold. Catherine awoke to a small pile of presents at the foot of her bed. She sat up and started opening them. She got a good book from her aunt and uncle, some candy and chocolates and a CD from Lily, other CD's from Mary and Arabella, and a gorgeous necklace from Severus. It was a white gold dolphin curling in its tail with her birthstone (the diamond) in the centre of where the tail curled. It was gorgeous. She was sitting there admiring it when Lily came in and gasped when she saw it.

"That's beautiful!" She said.

"I know," Catherine replied as she put it on. After Lily opened her presents the girls showered and got dressed then made their way downstairs for breakfast.

Once down in the Great Hall Catherine looked for Severus to thank him for his gift, but was disappointed when she didn't see him. Just as she was about to go sit down she felt arms wrap around her and someone kiss her neck.

"Happy Christmas, love." Severus said. She smiled and leaned her head to the side to give him better access to her neck.

"Joyeux Noël, mon amour." She replied. He growled slightly in her ear, which sent a shiver up and down her spine.

"It is so sexy when you speak French." He said. She smiled and turned around to face him and started giving him kisses. He was trying to deepen the kisses but she was resisting, after all, they were in the great hall with all the teachers present.

"Did you like my gift?" He asked, when they broke apart.

"I loved it." She said. "Did you like mine?"

She had gotten him a 'mans' bracelet in white gold that was three snakes intertwined.

He showed her that he had put it on, "Best gift anyone has ever gotten me." He said giving her a kiss. "My dorm is deserted, I wanted to know if you wanted to spend the night with me tonight?" he asked.

She looked at him wide-eyed, "Ees zat allowed?" she asked.

"Technically no, but I know some really good invisibility spells that will stop you from being seen." He said.

She grinned. "Okay, zen if zat ees what you want."

They spent the day wandering around the school with Lily. They had fun uncovering some of Hogwarts secrets. The day passed quickly and Catherine was in her dorm telling Lily about her plans for that night.

"Oh you mustn't! You'll get into so much trouble if you're caught!" she said sounding nervous.

"I'm not going to get caught Lily, Severus taught me ze Disillusionment Charm. I'll use zat to get to ze Sly'derin common, zen use eet again in ze morning to come back." She said trying to reassure her friend. Lily didn't look convinced but agreed not to tell anyone.

"Just don't get pregnant!" she said. Catherine stopped and stared at her surprised.

"If we would get zat far tonight, I can assure you, I know all ze necessary charms to avoid such a disaster." She said.

"Oh and you don't think those are his intentions?" Lily said sounding a little frustrated.

"I know perfectly well what he wants to happen. He's been wanting it for awhile, eets been me zat 'as been stopping eet." Catherine said.

"Really?" Lily said sounding surprised. "But…you're so…"

"Experienced, yeah I know, but I feel different about zis one. I don't know what or why, eets just different." Catherine said looking at Lily, and then laughed out loud at the look on her face.

"I thought Severus was being the virgin saint. You know, wanting to wait for marriage, but then started thinking with his other head." Lily said sounding surprised.

"I can assure zat 'e ees no virgin." Catherine said with a smile.

"What! No! He never told me! When, who?" Lily said sounding excited.

"I'm not telling you, 'e will tell you if 'e t'inks eets necessary" Catherine said. She stood up and did the incantation for the disillusionment charm and stood back and looked at Lily.

"It's perfect, I can't see you at all." Lily said. "Good luck."

Catherine bade her goodnight and made her way towards the dungeons very quietly.

She got to where the common room was and found Severus waiting outside for her.

"I'm 'ere." She hissed and he jumped. He regained control and walked into the common room and up to his dorm with her. She looked around the common room; it was completely different from Gryffindor's. Gryffindor's was warm and welcoming, while this one was just cold, and made one feel very uneasy. It looked like it was under the great lake. Once inside the dorm, she removed the spell and sat down next to Severus on his bed.

"I'm glad you came." He said. "I thought once you told Lily she would convince you not to."

"She tried, she ees a prefect, eets 'er duty to try and get me to follow ze rules." Catherine said, lying down.

"I'm a prefect to, but I will try my hardest to convince you to break them when it benefits me." He said with a smile and lay down next to her. She suddenly felt nervous. She knew what he was expecting, and it's not like it was her first time, but for some reason she felt the same way she did when she was about to lose her virginity.

"I feel nervous." She said.

"Well it's normal to feel nervous when your risking getting expelled if you're caught." He said.

"No, eets not zat. I 'ave no clue why, but I feel like you're expecting some'zing and you won't be satisfied." She said awkwardly. He looked at her surprised.

"I'm not expecting anything. I just wanted to spend Christmas night with the woman I love, that's all." She smiled at him,

"Really?" she asked.

"I won't say no to whatever you want to do, but yes really, I just wanted to spend the night with you." He replied. She smiled and crawled on top of him and started kissing him. He returned her kisses enthusiastically, and started running his hands all over her body. She started rubbing up against him and he let out a moan as she felt him get hard. She was unbuttoning his shirt as she continued kissing him rubbing her tongue on his. After about five minutes both were stripped of their clothes and left just in their undergarments. Catherine started to remove his boxers but he stopped her.

"Are you sure?" he asked.

She nodded, as she removed them. She looked him in the eyes and saw that he was a little embarrassed. She grinned at she started kissing her way down his chest. He was groaning with pleasure from her soft kisses on him.

"Do you like zat?" she said looking up at him. He nodded and she crawled on top of him and started rubbing herself against him while she continued kissing him. He was moaning and holding onto her hips. He wanted to be inside her but didn't want to push the matter.

"Catherine, please stop." He said.

"What ees wrong, you don't like eet?" She said sounding worried as she sat still on top of him.

"I love it, but I made a promise to you that I wouldn't do anything, but I swear if you don't stop I may not be able to keep that promise." He said looking at her. She smiled and leaned down and continued kissing him. "I'll take ze chance," she whispered between kisses. He let out a moan and kissed her back as she continued her teasing. He was trying to get inside her but every time he got close, she moved away so he couldn't.

"Please…Catherine…I want you." He whispered. She giggled as she slid him in just a little bit. He let out a moan, and tried to push in all the way but she wouldn't let him. He was going crazy, and she was loving it. Finally after a couple more minutes of torture and casting the right protective charms, she slid him in all the way, and they both let out a loud moan. She started moving up and down taking full control and he was losing control. He wanted to make it last, but it was too good.

"Wow," was all she managed when they had both finished. "Zat was…wow..."

He grinned as he slid down beside her, pulled her into his arms and together they fell asleep.
