Hi, I really hope you enjoy this fic, but there are a few things you need to know. This fic is seriously for mature peeps. if you are underage or too sensitive please don't read. It has fantastical adult themes, extremely strong language, tons of sex and MerDer, MerMark, and DerMerMark relationships. The chapters always start with who it's about so if you just want to read specific ships, you can. And, of course, I disclaim ownership of Grey's Anatomy and everything associated with it.

Three's a Fantasy

Meredith and Derek

Meredith knelt on a nest of bed linen in the supply closet and with practiced ease sucked strongly on Derek's rock hard cock, holding the base as tightly as she could in one hand. He tasted clean and salty, his skin smelling typically of himself. Her nipples pearled and her wet pussy dripped creamy juice down her inner thighs. She was turned on even more by Derek's natural sexy scent.

Her belly rippled with excitement as she listened to his humming moans deep in his chest. Her other hand strayed to her own nipple and she plucked and pinched it frantically, stimulating herself into mewls of passion around the organ filling her mouth. She squirmed in need at his feet and watching her, he couldn't help the sexy grin that crossed his face. He loved her heat. She was amazing. He stroked her dark honey hair back around her ear as she slid her hand down her belly through her neat light brown nether hair to her sex. She dipped two fingers into her creamy twat and slid deep between her own inner folds to find her hooded clit. She rubbed it gently with her moistened fingers, squirming hard, blissfully giving Derek head the whole time.

"Suck me harder, baby...," Derek breathed in sharply as she obeyed, "Your mouth feels like heaven, honey... yeah... just like that. So wet... so hot... that feels sooo goood," he groaned.

His cock was satiny soft skin over steel hard meat. She scraped it up and down with lip covered teeth as fast as she could, her head bobbing and her eyes closed. He smiled in sexual bliss as he watched his girl blowing him so happily. One of his clever surgeon's hands cupped her concave sucking cheek holding her head firmly in place, although she didn't need the encouragement. The other tightly gripped the linen rack over his head as he moaned in ecstasy. His dong bounced off the back of her throat with each bob.

She paused a second and panted through her mouth for breath, still tonguing his large member. He groaned in delight as her hot, moist breath blew over the sensitive dark red head and her agile tongue found the tiny slitted crease at the tip of his cock's head. She delicately traced her tongue around the velvet head to the sensitive neck and then closed her lips again over his heavy erection. She hotly sucked the tip only, tonguing him madly. He petted her hair back from her face so he could see her loving erotic intensity.

He watched her glossy lips stretch around his thick cock and then slide up and down the length of his erection, again always maintaining the perfect suction. His cock glistened wetly in the dim light from her saliva. Her tongue circled the knob, caressed the ridge and then lapped his straining shaft. She lapped his testicles and gently rubbed them in one hand. His balls tightened into hard knots close to his body.

She rose back up and this time sucked his cock into her mouth as far as it would go. She held it there and sucked, gripping his buttocks in both hands and pulling him tighter to her mouth. She used no motion now; she just sucked as hard as she could, tasting drops of his pre-cum.

Derek watched her cheeks and lips and throat rhythmically sucking his prick. She was exquisite. She had about two thirds of his cock stuffed deeply into her mouth while she valiantly attempted to swallow down more, making moist little, grunting, suckling noises that drove him wild. Her smooth cheeks were flushed raspberry pink and her lips were an even darker red raspberry. Her long eyelashes fanned over her mysterious dark green eyes casting shadows over her eyes and cheeks. His dark eyes started to roll back in his head with pleasure. His cum churned in his balls.

"Meredith... I'm cumming, baby. You have to... stop... if you want... me to...," Derek lost it.

He held her jaw and rapidly fucked her mouth. Glorious sensation welled up and flooded him. He shot his white sticky load into her mouth once, twice, three times, while she gulped greedily, supremely satisfied that he'd lost his iron control. He bit his own lip to stop himself from shouting his release, his eyes slamming shut and his breath sawing harshly. Derek's knuckles turned white where he gripped the linen rack and his body shuddered hard. His hard belly sucked in and rippled.

Meredith continued to kiss and suck his cock until it softened its rigid posture, resting long and stretched against the cushion of his testicles. She finally sank back onto the floor still writhing and panting wantonly, her breasts tipped with large, raspberry beads of lust and her creamy pussy scenting the air with her need. She parted her legs and rubbed her hungry little twat until she moaned, watching him through hooded eyes.

"Derek..." she pleaded.

He struggled to open his eyes and look down at her twisting form. His body was still tremoring with left over excitement. He rubbed a hand over his chest and belly and cock absently.

"Ah, baby, I'm not quite ready yet to give you what you need. What would you like instead, while I recharge?"

Meredith lifted her arms to him wanting to be held and kissed and praised. She wanted to feel him explore, tantalize and tease every inch of her skin. She wanted him to bounce and balance her breasts on his hands.

Meredith needed him to kiss and suckle her nips until they were as hard as diamonds and leaking fluid. She needed him to finger fuck her juicy pussy and lick it clean. She wanted him to rev her to a fever pitch so the slightest touch would act as a match to a bonfire.

Then she wanted him to bury his huge cock so deeply in her tumescent pussy, she'd feel it banging in her throat again. Meredith needed Derek to fuck her hard and fast, sweet and slow, deeply and shallowly – anyway, every way there was. She needed him to love her, love her loud and long.

They'd been separated for over two weeks, hence the desperate meeting in the closet. Derek had been out of town teaching seminars in three hospitals in Arizona and two in Utah. Before that, Meredith's crazy intern schedule had kept them apart. Used to making love at least twice a day, they were both crazed with need for each other. Derek had literally snatched his girl out of the hallway, as she trotted along delivering lab reports, and shoved her in the linen closet, locking the door behind them.

"Okay, honey, up you get. You're amazing. Your mouth is so good, I have dreams about it at night," he grinned when she giggled sexily, "Yeah, I can still have a wet dream like a teenager over your talented, sexy mouth."

He reached down to her and lifted her full length against him, supporting her weight completely. She wrapped her arms around his shoulders and rubbed her face into the hair on his chest. She kissed his collar bone and licked the hollow above it, wallowing in his delicious scent. He turned her a little sideways, rubbed her plump little ass, and then supported her back.

He slid a hand over her soft, curved little belly to her breasts. He lowered his lips to hers and kissed her lovingly while he cupped and lifted her breast. Its sweet weight stirred a twinge of desire in his gut and made his cock perk up. Derek gave a throaty growl as he bounced her heavy breast in his hand and flicked the tip with his thumb. He pressed a hand on her back and slid it down the crease between her chubby buttocks. He explored lower and found her thickly cream coated vagina. He pushed three fingers hard into her sweet spot and hand fucked her. She gasped and mewled, incoherently trying to talk, squirming on his hand for the best angle.

Her fat, ripe nipple pouted at him for attention so he closed his teeth around it and lightly chewed while she squealed in his ear. He made it better by warmly licking it. He sucked the bud into his mouth and rhythmically milked it, letting his tongue occasionally spank it.

Meredith moaned and squirmed in his arms, twining her arms around him, and sinking her fingers into the warm silk of his hair until she reached his scalp and rubbed. Derek eased his fingers from her gripping pussy and grasped her plump ass in both hands. He slid his thigh between her wet thighs opening her juicy pussy against his hair roughened skin. She squealed again, panting hard, as he rubbed her up and down on his thigh, stimulating her clitoris to its maximum swollen size.

She enthusiastically rode his leg, rubbing and squirming wildly while he suckled her second nipple, enjoying her soft gardenia scented breast pressed to his face. Finally, she was so loudly vocal, he covered her beautiful mouth with his own to swallow the sound and suck her tongue as he had sucked her berry nipple.

Meredith needed his cock inside her. She couldn't stand anymore foreplay. She jerked her mouth from his and laid her head on his shoulder, feeling his stiff cock pressing into her soft belly.

"Derek," she begged, reaching for his cock and trying to climb up on it, "pleease, baby, pleease! Put your cock in my pussy. Fuck me. Fuck me hard, babe, please, fuck me, fuck me..."

Her breathless pleading petered out when he shoved her against a rack filled with oversized cardboard boxes and lifted her up. She wrapped her legs eagerly around his hips. He pressed his thick cock to her pussy lips, listening to her eager whimpering turn into an intense wail of fulfillment as he thrust inside. Her dripping wetness let him shove all the way to the hilt, finally stuffing her full, finally stretching her wide. Derek covered her mouth with his and fucked her mouth with his long tongue even as he finally fucked her pussy as hard and as fast as he could with his rock hard cock. He banged her mercilessly into the cushioning cardboard behind her as she rode his rigid pole. She shrieked into his mouth, uterus and vagina contracting, and cumming hard.

She thought he'd stop but he didn't. Derek laid Meredith in her nest of bed linens on the floor and kept fucking her. He filled her mouth and tight, hot pussy over and over, not letting her rest. She shrieked and came again, but still he pounded, not giving her any time or space to regroup. She whimpered and tried to turn her face away. He denied her and made her do it his way for her ultimate pleasure. He held her face still and tongue fucked her furiously, occasionally sucking her bottom lip.

He pinched and twisted her nipple lightly and was rewarded by another shriek of orgasmic ecstasy. Meredith laid back exhausted now, unable to hold him anymore, while he pounded his cock into her creamy sheath without let up. Her body rocked with the pounding, her breasts bouncing , her head tossing. Sensation impossibly built again and she rippled with orgasm on top of orgasm. She undulated up against her lover, one foot pressed to his thigh, the other rubbing up and down his hair roughened leg.

"Oh God, Meri!"

His ass clenched, and he pumped his cock twice more as his balls exploded. Meredith felt his hot cum spray inside her as he shouted against her throat, icy hot sensations sparkling from his testicles to his spine. They danced from his sacrum to his neck and back again. He bit her throat and sucked her soft flesh. She wailed softly again and again as she came one last time.

Tears of overwhelming ecstasy leaked down her face. Clear liquid drops leaked from her breasts. Milky cum leaked from her pussy and his soft penis, even as they parted from each other. As Derek rolled to his side off of her, long white strings of mating fluid stretched between them, as if even now they couldn't be separated. He stroked her quivering belly and breasts soothingly.

"Sh, hush, baby, sh," he crooned.

She turned on her side facing him, looked deeply into his dark blue eyes and said, "Welcome home, I missed you."

He smiled his sexiest man in the world smile, sated and satisfied.
