Title: Parasitic

Disclaimer: Do I own House? Nope, can't say that I do. Would I like to? HELL YAH!

Summary: Greg and Allison House are back from their honeymoon, and still basking in the glow of newlywed bliss. But what happens when a Christmas surprise makes a very abrupt change in their lives. Is the fun over? Or just beginning? Sequel to Contagious (Do NOT, I repeat DO NOT read this without having read Contagious! If you do, you won't know any of the characters or really... Anything- So check out Contagious first and come back to this!)-Andi A/N- I changed my mind when overcome by the X-mas spirit, so I began the story in a different place than I originally intended to. Don't worry, you'll get it ;) Chapter One: It's A Wonderful Life

Allison sighed as she woke up beside her husband. Sitting up in bed, she smiled at the sight of Kane lying on the foot of the bed. Greg's arms encircled her waist, as he slowly awoke. "Morning." He mumbled, burying his face against her hip.

"Mm, merry Christmas." Allison smiled at him, turning in his embrace and sliding down to lie beside him.

"Christmas?" Greg sighed, "That would mean, we've been married for officially, two months and four days."

Allison laughed, but quickly stopped, and rubbed her stomach, "Oh jeez." She felt the churning of stomach acid, "This is getting ridiculous." Allison groaned, covering her head with a pillow.

"Acid reflux?" Greg pried the pillow away.

"Ever since we came back from Kyoto, nothing has agreed with my stomach." She mumbled, pulling the pillow from her face, "Maybe it was the change in my diet, or I don't know." Allison managed to push back the urge to vomit.

"But you loved it there." Greg insisted, "I didn't do a bad job picking our honeymoon location, right?" He teased, kissing the nape of her neck and placing his hand over her stomach, as if to try and help her settle it.

"I loved it. All the temples, and you speaking Japanese?" She laughed, "That was amazing all by itself. Discovering how even more brilliant my husband is than I first thought." Allison gave him a soft kiss.

Nodding, Greg gave her rear a soft pat, "We need to get up and moving if we're going to meet your family at Stephen and Morgan's new home. It's going to take forever to drive there."

Pouting, Allison braved herself to exit the warm cocoon of their bed.

-------------------------------------

Greg glanced over at Allison as they drove to Stephen's house. She had been acting very funny all morning. Not funny haha. Funny in a "something's not right" sort of way.

Rubbing her pectoral muscle, Allison grunted, making Kane, who was in the back seat, set her face on the back of her seat sympathetically. Now she really regretted not wearing a bra, but the way the snug fitting sweater dropped at the shoulders she would be showing straps and strapless bras always hurt her sides! Damn style!

"What's wrong?" Greg asked, finally too curious to keep it to himself.

Allison shrugged, dropping her hand back to her lap and leaning her head against the cold pane of the passenger's side window. "Nothing." She replied hollowly.

"Uh huh." Greg looked back at the road, trying not to divert his attention from the road that was now dusted in a new layer of snow.

With a tiny whimper, Allison flopped back into her seat, rotating her hips as if to put to rest a dull ache in her lower back.

Greg sighed, catching the movement out of the corner of his eye. "Ally?"

"I just don't feel right." She replied, feeling ready to cry from frustration. "Left here." She pointed at a road. Greg turned and she pointed to a dark green house. "Right there."

Greg pulled into the driveway and got out of the car. Walking over to her side, he helped her out of the car and placed his hand on her lower back, applying pressure on either side of her lower spine just above her sacrum. Allison leaned against him, feeling a welcomed relief from the ache in her back. She must have contorted herself when she was sleeping.

"Go inside and sit down. I'll bring the gifts in." Greg told her. Allison nodded and headed towards the door as Greg went to the side door and released Kane from the back seat.

Grabbing the gifts from the trunk, Greg was grateful that Allison had put them in a bag so they would be easier to carry.

"Hello, Cameron family." Greg called as he passed the door.

"Hello, House family!" Morgan bounced excitedly. "I'll take those." He offered, taking the bag of gifts from Greg and running to place them under the tree. "You're just in time. Bryce brought "It's a Wonderful Life" and we're going to watch it before dinner." He explained. "And then, it's gift time!" Morgan was as giddy as a toddler on... well.. Christmas day.

"Great." Greg followed the hall to the kitchen and saw the Tv room to his left. "This is a nice house." He told Stephen.

"Thanks." Stephen was brushing his hands on a napkin. "There's a vegetable tray if you're a little hungry, and chips and dip in the living room." He gestured to the small card table that was against a wall in the tv room.

"Your parents aren't coming?" He noticed the lack of Mr. and Mrs. Cameron.

"No, mom's not big on traveling on holidays... Freaks her out." Stephen rolled his eyes. "But they're going to be dropping by around March." He explained. Greg nodded, spotting Allison already flopped on the couch. "Hey," he nudged her foot and she lifted them so that he could sit down before plopping them in his lap. Greg smiled at her gently. She looked ready to fall asleep already.

"Hi, Greg." Loli smiled from a spot on the loveseat, where she sat with her husband.

"Hi, Loli, how are you?" Greg asked, running his hand over Allison's leg.

"Fine- Oh! Hi, Kane. Yes, yes, sloppy kisses." Loli tightened her lips as Kane licked her face. She tilted her head up to get a few laps under the jaw as she continued talking to Greg, "So, what's wrong with my little sister?"

Greg shrugged, "She hasn't been sleeping very well lately because of her upset stomach. She just hasn't been right since around the time we got back from Japan. And her back's been killing her too."

"Aw, my poor baby sister. You don't think you caught something do you?" Loli asked.

Allison gave a weak shrug as Bryce came in with his son in his arms and started the movie. The smell from the kitchen was putting her stomach in knots.

"Here, Ally, I made you some peppermint tea." Stephen offered her the mug. Allison smiled gratefully as she accepted the hot tea. As she sipped it, her stomach settled a little, and she didn't feel so much like she was about to throw up all over the floor. Amazing what a little tea can do...

Together, the family watched the movie, enjoying the classic. At some point, though, Allison fell asleep, only to be awoken when the movie had ended and they were ready to eat dinner. "I'm not hungry." Allison mumbled, lying on the couch limply. She didn't want to move, every limb feeling like lead.

"Come on." Greg helped her sit up. "Maybe a little food will make you feel better." He coaxed, holding her hand as she stood up slowly. Allison sighed, leaning a large amount of her weight against him.

As they sat around the dinner table, Allison sipped another mug of tea. Though her nausea had decreased, she didn't feel like it coming back full force. She nibbled on a crescent roll as everyone dove into a piece of meatless lasagna. After she had a little food in her stomach, she felt the queasiness dissolve and began eating the meal that was in front of her. The food didn't smell so repulsive as she began eating it.

"Feeling better?" Greg asked sarcastically.

Allison nodded as she ate a bite of lasagna.

"Slow down." He warned, and Allison obeyed.

Conversation broke out, now that everyone was in a good mood, and soon it was like every other holiday. Allison felt guilty that she'd brought down the holiday cheer with her nausea. Still, she couldn't quite figure out why she had felt so ill.

She'd been feeling this way for weeks now, and though she'd love to blame it on Japan, she still had an inkling that it was something a little different. Sitting back, Allison rubbed her pectoral muscles, and as she did, she froze. Silently belittling herself, Allison wondered how a doctor could be oblivious to such ques.

Keeping her realization to herself, Allison went back to socializing with her family.

---------------

Greg kept side glancing at Allison as they drove home, and he knew that she was aware of his curious looks because she was looking at him, wondering why he kept looking at her.

"Are you feeling better?" Greg finally asked as they exited off of the main highway. She was rubbing her stomach like it was bothering her, but her gaze was contemplative.

"Yeah." She smiled softly, leaning her head against the window. Allison wanted to tell him she was almost positive she was pregnant, but she wanted to wait until they got home and she could take a pregnancy test. Luckily she had kept the second test that had been included in the box when she thought she was pregnant before.

"Ally-" "I'm fine, Greg." She promised. "How much longer until we're home? I need to pee."

Greg laughed, "About another ten minutes." He answered.

Allison smiled and closed her eyes against the cool window pane. When she opened them again they were parking by the apartment building and she felt a jolt of anticipation rush through her. Getting out of the car excitedly, Allison ran as quickly as she could, bolting for the apartment. Greg nearly slipped on a patch of ice in the road trying to keep up with her as she ran to the door. "Ally!" He called out. "Ally, your presents."

Giddily, Allison waved him off as she continued for the door. "Come on!" She called out to him.

"What's your hurry?" He finally caught up to her at the elevator. "Are you giving me Christmas sex tonight? Cause we have a few hours before Christmas ends." Greg leered at her, wrapping his arms around her waist.

Allison bit her lip, a smile tugging the edges of her lips. As they entered the elevator she began to wonder. Should she tell him now? Should she wait until they got to the apartment? Should she wait until after she took the test?

Excitement getting the best of her, Allison flung her arms around Greg's neck, "I think I'm pregnant." She declared.

Greg's jaw dropped, "What?"

Allison felt the giant balloon in her stomach begin to deflate. "I... I think I'm pregnant?" She felt unsure now, she'd thought he was going to be happy!

Grinning wide, Greg pulled her tighter to him, "Do you have a pregnancy test?" He asked. "Or were you going to sneak off and take it without me again?"

Allison's heart lifted. "So that was a good shocked expression?" She double checked.

Greg nodded as the elevator dinged that they'd arrived on their floor, "Let's go see if we made a baby." He took her hand and walked as quickly as he could to the apartment.

Greg was pacing outside the bathroom door, "Aren't you done yet!?" He called, waiting for her to get the test started, "I thought you said you had to pee!"

"It's hard to pee when someone's yelling at you while you're on the toilet!" She yelled out, feeling too tense under pressure. "Can't you shut up for a minute!?"

"The test responds in 3 minutes! I'll miss a whole minute of waiting!" He answered in the same yell. "I remember when they took 20 and women had to wait a week after they missed their period... By which time, women already figured out they were pregnant!" Allison laughed on the other side of the door and Greg heard the toilet flush. "Can I come in now!?" He asked excitedly.

"Ye-" Greg burst into the bathroom.

"ah."

The test was sitting on top of the sink as the two sat on the tub looking at Greg's watch. Allison was biting her lip. Greg was tapping his foot.

"Five, four, three, two, one!" They said excitedly in unison before they stood up and looked at the little plastic wand.

Two pink lines.

"I'M PREGNANT!" Allison screamed, flinging her arms around Greg. He planted kisses all over her face, squeezing her tightly to him. "I'm pregnant! I'm pregnant!"

Leaning his forehead against Allison's, Greg smiled wider than he could ever remember. "When do you think we did it?" He asked, trailing his finger's down her spine.

Allison was beaming, "It could have been our second go under the piano..."

"Or in the shower."

"Or-" "I don't mind where it was." He told her breathlessly, "I'm just happy that it happened."

Allison planted a soft kiss on his lips. "We have so much to do..." She pulled back with wide eyes. "We need to turn the second bedroom into a nursery, we need a crib-"

"Yes, yes, we'll need a bunch of stuff, but tonight..." He began leading her from the bathroom into the bedroom, "Tonight, I want to make love to you." Greg pushed her onto the bed, slowly towering over her until his body covered hers.

"Mmm, I like the sound of that." Allison grinned as Greg began pulling her clothes aside.

Pulling up her shirt slowly, Greg planted feather light kisses on her stomach, following the freshly exposed flesh up her chest. Allison helped him pull the shirt off completely, and flung it off to the darkened corner of the room. She wrapped her arms once more around his neck, pulling his lips to hers. Greg let his tongue trace over her bottom lip before waging war against her tongue. With a laugh brimming in her mouth, Allison pulled away and let him burry his face against her throat. Nipping and sucking the tender flesh, he left a dark hickey just beneath where he knew most of her shirt collars covered.

Allison moaned as he trailed kisses further down, arriving at her breasts. She groaned in appreciation as he carefully kissed the over sensitized mounds. Loving a doctor had its benefits, he knew how to take care of her...

Sighing his name, Allison closed her eyes, rotating her hips against his body as he went lower.

Greg undid her pants and pulled them off of her body, kissing his way back up her long legs. Allison rotated her hips as he came closer to her sex, a heated anticipation coursing through her blood. Her back arched slightly when he placed a gentle nip on her inner thigh, a soft moan catching in her throat.

His tongue caressed her swollen nub, making her sigh in rapture. Greg ran his hands up her thighs, spreading them wider as he enveloped her clit with his mouth. Allison moaned and rolled her hips as he flicked his tongue over her sensitive flesh. Nerve endings were set on fire as her receptive body felt every caress of his hands and every stroke of his tongue, making her feel like she could tumble over the edge at any second.

As Greg's fingers gently glided into her slick entry, Allison cried out and bucked her hips upward. Her juices coated his fingers, making them slide into her even faster. Using his hands to send her over the edge a second time, not even letting her come down from her first climax, Allison screamed his name loud enough for him to wonder if the neighbors were now awake.

Sliding up her body, Greg broke contact only to lower his pants and position his cock over her quivering sex. Allison wrapped her arms over his neck, urging him to enter her. Abiding to her wishes, Greg thrust in slowly, letting her feel ever inch of him fully. He steadied her hips to keep her from arching and drawing him in any faster than he wanted her to.

Allison whimpered, needing him to fill her completely. She wanted all of him, but he denied her.

With another cry, Allison shook in his embrace until he was halfway in. Drawing back, Greg noted, with some amusement, that Allison was not pleased with his early withdrawal. Slowly, he began sliding back in, making her groan.

"Greeeeeg." She finally moaned, wanting him to stop the torturous administration.

Complying Greg thrust in completely, taking her off guard. Allison cried out in surprise and pleasure as he was suddenly pressed into her entirely. Beginning a rhythm, Greg released her hips and held her close to him as their hips rolled together. She was slick with excitement, allowing him to thrust freely within her.

Their combined movements took each other over edge until both were left panting for breath as they collapsed in exhaustion beside each other.

Tired and sated, Allison curled up beside Greg, her arm flailing over his chest as she quickly fell asleep. Catching his breath, Greg held his lover to him and smiled, letting his hand drift over her belly as he pulled the blanket up and over their bodies.

Waiting until her breathing had become rhythmic, Greg wriggled from her loose embrace and delved beneath the blanket he'd covered them with. He curled up against her body, placing his ear over her stomach. Though he would never hear the rapid heartbeat through the louder sounds of her body, Greg imagined the thrumming sound as he placed his palm over his growing child.

Being a doctor couldn't stop the sudden awe he felt knowing that he'd helped create the baby growing inside Allison's body. And being a doctor couldn't stop him from placing a gentle kiss over her stomach, despite the knowledge that the baby wouldn't feel it. Everything he'd known couldn't prepare him for the sudden protective surge he felt as he held Allison close to him.

Despite the fact that he still considered a fetus to be a parasite, Greg grinned, knowing it was his parasite.

"Hello, my little cestoda." He said softly, "I'm your daddy."

Hehe, that was a little creative exercise, and it was not meant to hinder the production of the sequel, but it unfortunately did :O.
