So fluff… it's what we all live for really isn't it? There wasn't much in the last chapter so that's why I've updated so quickly :) Hope you like…

At five o'clock Meredith and Derek were in the car driving home. Lily was asleep and so was Meredith so the journey was silent. The sun was slowly setting over Seattle when Derek pulled off the main road and onto the track that led to their home. The house that they built on his land was a modest one, Meredith had insisted that it be simple and not "showy" and he was all too happy to oblige. He pulled into the drive and turned the engine off and looked across at his sleeping girlfriend. He didn't want to wake her, she looked so peaceful. Derek gently shook her and Meredith's eyes opened slowly. She yawned and stretched her arms and looked at him sleepily. He leant across and kissed her gently.

"We're home sleepy head, you and Lily have been out for about half an hour," he said quietly. Meredith nodded and undid her seatbelt and got out of the car and walked slowly towards the house waiting for Derek to follow with Lily. She unlocked the door and walked into the house, leaving the door open, and went into the living room and collapsed on the sofa. She heard the door slam and Derek appeared in the doorway. He walked over to Meredith and set Lily's car seat down at her feet and he lifted the little girl out and handed her gently to Meredith who snuggled her close. Meredith sighed happily, rubbing her baby's back and shutting her eyes. A year ago it was surgery that made her this happy, but just holding her daughter now brought her more pleasure than a scalpel ever had. Derek smiled at his fiancé and walked over to the kitchen and put the kettle on.

"Do you want tea Mer?" He asked opening the cupboard above his head pulling a mug out.

"That'd be amazing Der," came the reply and he chuckled, taking setting another mug down on the counter.

"Hey Derek?" Derek looked up from watching the kettle into the living room where Meredith was now standing, Lily still tucked up against her chest.

"Yeah sweetheart?"

"I'm gonna take a bath… bring my tea upstairs?" Meredith said persuasively.

He smiled at her and nodded, "Of course, go ahead. I'll be up a minute okay?"

"Okay." And she left the living room and climbed upstairs. She walked into the en suite bathroom, still holding Lily, and turned the taps on. She walked back into her room and laid Lily in the middle of the bed where she started to wriggle, making Meredith laugh.

"You're a little menace aren't you? You just can't keep still." Meredith said to her daughter who now had her fist in her mouth, "Well mummy is just going to undress and then you and her are going to have a lovely bath together, yes we are!" She reached across and tickled her daughter who smiled up at her mother. Meredith finished undressing and then carefully removed her daughter's clothing and nappy, which she disposed of hastily. She lifted her off the bed and walked into the bathroom, and making sure the water wasn't too hot, she stepped into the bath.

The warm water was soothing and Meredith slowly relaxed and leant back against the side of the tub, Lily nestled against her. After a few minutes Meredith lifted Lily from her shoulder and settled her against her chest and began to feed her daughter. She heard the bedroom door open and then Derek knocked on the door.

"It's open!" She called and Derek opened the door and came in and set a steaming mug of tea down beside Meredith.

"Just how you like it, milky with lots of sugar!" He chuckled, "Barely tastes like tea at all…" He kissed the top of her head and walked out of the bathroom, returning shortly with his own mug of tea and a book under his arm. It had become something of a routine for him and Meredith; she would sit in the tub with their daughter relaxing and he would be on the floor reading a book or the paper. Every so often he'd look up to watch his two girls and he'd smile and catch Meredith's eye who would smile back and say, "What're you looking at?" to which he'd reply "You."

Tonight he was in the middle of reading "Picture of Dorian Grey". He'd recently gotten interested in 19th century literature and Meredith had recommended Oscar Wilde's classic, remarking "An ego to finally match yours Derek," at which he'd laughed and accepted the book gratefully.

"Hey Der," Meredith began.

"Yeah Mer," Derek's attention still on the book in front of him.

"I think our daughter gets cuter every day, don't you think?" He looked up from the novel and found her beaming down at her daughter who was now sleeping. The sight warmed his heart and he nodded in agreement.

"I do Mer, I do." He put his book on the floor and stood over the bath, "Can I hold her Mer?" She nodded and he grabbed a towel from the rail and lifted his daughter out of the bath and wrapped Lily up carefully so as not to disturb her slumber.

"I'm gonna put her to bed okay Mer?"

"Go for it sweetheart, I'll be out of here in a bit."

"Okay Mer." Meredith shut her eyes and immersed herself under the water. She quickly rinsed her hair and got out of the bath, drying herself with a fluffy white towel. She left the bathroom and turned out the light and walked back into her bedroom. She dropped her towel on the bed and went over to the full length mirror in the corner and looked at herself with distaste. Her hand toyed with the excess flesh on her stomach and her fingertips dotted over the few silvery stretch marks that lingered there.

"You are so fat…" She said to herself tiredly, sighing.

"No you're not." Meredith turned around and saw Derek watching her, his arms folded, his face kind and sincere. He walked over to her and wrapped her in his arms, his head resting on her shoulder so they were both looking in the mirror.

"Meredith, you are gorgeous you understand? Absolutely gorgeous." He said seriously, catching her eye in the reflection.

"Derek, you don't have to keep saying that…" Meredith sighed looking away. She hated feeling vulnerable and self-conscious, her appearance hadn't been something she used to worry about. But having Lily had changed that and whilst she didn't for one moment regret her daughter, it didn't make her feel any better about herself.

"Yes I do because it's the truth Mer, and for some reason you don't want to believe it."

"Derek it's not true! It can't be; I don't look anything like I used to… I still don't understand why you want to have sex with me anymore! I have a flabby stomach and massive swollen boobs. Not sexy. Not sexy at all Derek." She frowned at him and he shook his head.

"You are gorgeous. To me you are gorgeous. Those things you described, they remind me of our daughter Mer; you've changed because we created a life together and there is nothing sexier to a man than the mother of his children, believe me." He cupped her left breast with his hand, still looking directly at her reflection. "I happen to adore your swollen breasts, they're heavier and softer and they make you curvy and cute," he massaged them gently and she smiled at him, feeling slightly turned on from watching him touch her in the mirror. His right hand snaked down to her stomach and stroked it gently.

"You say you're flabby, but you're not Mer. You're not. You're just a little rounder and that's sexy Mer, it's so damn sexy. I like voluptuous Meredith as much as I like skinny Meredith, perhaps even more so. Voluptuous Meredith makes me want to do this!" His hand plunged downwards straight into her wetness and he rubbed vigorously at her clitoris and she arched against him taken completely by surprise. Meredith moaned as she watched her reflection; he rubbed harder and the hand on her breast found the nipple and started rolling it between expert fingers, turning her on even more. She squirmed against him, feeling her knees weaken as he pressed harder on her clitoris and she jerked against his body, feeling his growing erection on her bare back.

Derek watched Meredith in the reflection and her eyes shut tight in pleasure. He watched her place her hands on top of this, pushing them harder against her and he felt himself increasingly turned on.

"Derek…" She moaned, her eyes still shut, "Kiss me Derek… ahh!" She gasped and he bent his head and found her mouth, his tongue mixing with hers. She kissed him with fury and he felt her moan into his mouth as she came. He turned her around and pulled her into a tight embrace as her breathing returned to normal.

"Believe that you're sexy and attractive yet?" He whispered against her ear.

"Mmmmmmmmm." She replied and kissed his chest. Meredith began to grind her hips against his and it was Derek's turn to moan.

"Make love to me Derek… in front of the mirror, I want to watch…" she smirked up at him and kissed his surprised expression. His hands went to his shirt which he began to unbutton hastily, whilst Meredith pulled down his jeans. Once he was free of clothes, Derek pushed Meredith up against the wall in front of the mirror, lifted her legs up so they were round his waist and entered her hard. They watched each other in the mirror, writhing against each other, both moaning in ecstasy. Neither lasted long and they were left hot, sticky and satisfied. Derek pulled out and they both leaned against the wall in an embrace.

After a few minutes, Meredith began to mumble against Derek's chest, "Derek…"

"Yeah sweetheart?"

"You're kinda crushing me…" Derek laughed and moved off his fiancé. Meredith grinned up at him and grabbed his hand and led him over to their bed, turning the lights off as she went. She removed the covers and scooted over to her side and pulled Derek in with her, spooning him around her and covering them both with the duvet. She sighed contentedly and Derek kissed her hair. They lay together, silently entwined before Derek started speaking softly.

"Hey you never did tell me why Mark was acting so strangely…" Meredith sighed.

"You really want to know?"

"I really want to know."

"Okay… but you can't say anything to either of them. Promise me."

"I will keep my mouth shut," and he kissed her hair again, sealing his promise.

"They're trying to get pregnant, and in six months nothing has happened." Meredith sighed again, "They both feel like they're letting the other one down except they haven't said this to each other. And today with Lily, I think it all got a bit too much for Mark…that's why he was acting weird for a bit."

"Oh Mer, that's awful…" Derek hugged Meredith closer to him, "I had no idea…"

"Yeah…Derek, do you know how lucky we are to have Lily? We could've been just like Mark and Addie…" Meredith turned to face him, burying her face in his neck. "I don't want to talk about this anymore Der… it makes me sad."

"Okay Mer, we'll stop. Go to sleep sweetheart," Derek kissed her forehead and let her shift to get comfortable against him.

"Night Derek, I love you."

"Love you too Mer." And they both fell into a deep slumber.

So that was all very fluffy lol :) hope you enjoyed it, I'm afraid it gets considerably less fluffy hereafter… for now though please read and review!
