Author's Notes: This is an idea I got from a dream I had, which was inspired by late night roleplay. I'm not sure how many chapters it'll be, depends how much i can drag out the plot. As a little prewarning, it will contain mpreg.

One Night Only

Prologue:

Morning broke over the Shinigami realm. Eric opened his eyes slowly, groaning as his head began to ache. Apparently he had a hangover. Exactly how he had got the hangover was a complete mystery to him. He remembered leaving work with…someone, going to a bar and then nothing else. Eric sighed to himself and settled back down to sleep. He figured Alan would probably tell him in detail what he had done last night as soon as he woke up. Eric closed his eyes and rolled over, wrapping his arms around the person next to him. A cold shiver raced down his spine. The person he was holding was definitely not Alan. Eric gently felt the mystery person, feeling the unfamiliar contours of their body. The person giggled,

"Eric darling, that tickles"

Eric opened his eyes sharply; long red hair invaded his vision,

"S-Sutcliff?" he stammered. He hastily scrambled away, falling off the bed straight onto the floor. Grell sighed and slowly sat up in the bed, delicately holding the sheets around his bare chest with one hand,

"Honestly love, even after last night you're still calling me by my surname?" he said "Not even Will is that cold",

"L-Last night?" asked Eric, "W-What happened last night?" he knew he was going to regret the answer as soon as the question left his lips. Grell sighed again and rolled his eyes,

"Let's see, we're both naked, in a double bed, in a cheap motel" said Grell "What do you think happened darling?". Eric's stomach sank. A sickening feeling rose in his throat. He turned and ran to the bathroom, violently bringing up whatever in hell's name he had eaten last night. Grell pouted and followed Eric, using the bed sheet as a temporary night dress,

"I take that as an insult you know" he said. Eric groaned,

"Sutcliff…Grell….shut up" he muttered. Grell pouted even more,

"Charming, and I thought last night was amazing" he giggled and looked at the ceiling dreamily, "So rough, so passionate, ahn! You're such an animal darling" Eric gagged and almost threw up again. Grell sighed, placing one hand on his hip,

"Honestly, you don't have to be such a baby about this" he turned and walked out of the bathroom "Let's just get dressed and leave, I'm sure poor Alan is worried sick about you",

"Crap, Alan!"

Eric jerked his head up, yelping when the toilet seat fell on him. He stood up and flushed, leaving the bathroom. He began to gather his clothes from where they had been scattered the night before (exactly how his boxers had ended up on the light fixture he wasn't sure, but he decided he was better off not knowing) and started to get dressed. Grell watched him as he sat on the bed,

"What's the hurry love?" he asked "It's only half eight, we don't have to check out till noon"

"I need to get back before Alan realizes I'm gone" said Eric. He pulled on his pants, groaning when he saw they were back to front. He pulled them off and hastily put them back on again. One pant leg caught underneath his foot as his stood up, he yelped as he overbalanced and crashed to the floor. Grell burst into laughter. Eric growled and ripped them off,

"What is wrong with these pants?".

Grell continued to laugh. He stood up and walked over to Eric, helping him onto the bed. Gently, he took Eric's pants and helped him put them on,

"Calm down love, you're getting too worked up" said Grell. He picked up Eric's shirt and helped him into it, "I'm pretty sure Alan has noticed you're missing by now, otherwise he should get his eyes looked at". Eric sighed,

"Yeah, I guess your-" he paused as Grell began to put his socks on. He glared and moved his foot, "I'm not five Sutcliff, I can dress myself". Grell pouted and dropped Eric's other sock,

"Well, after the performance with your pants I had my doubts" he muttered. He walked away from the bed and began to put his own clothes back on. Eric sighed and finished dressing,

"You know, I thought we shared something special last night, even if we were blind drunk" said Grell, still pouting "I always thought you were a kind, sweet, strong, handsome man, guess I was wrong…". Eric groaned in frustration,

"Look, if I buy you breakfast will you please stop guilt tripping me?" he said. Grell immediately stopped pouting and grinned,

"Do I get a good morning kiss too?" he asked. Eric sighed and pinched the bridge of his nose,

"Alright, but keep your hands where I can see them" he said. Reluctantly he walked over and gently kissed the redhead's lips. Grell squealed happily,

"Ahn! I love the feel of you soft lips on mine!" he said "The tingle of your facial hair on my womanly skin!" he wrapped his arms around himself and continued to swoon. Eric grimaced and scrubbed his mouth with the back of his hand,

"Are you happy now?" he said,

"Very happy" said Grell. He latched onto Eric's arm and hugged him tightly "I'm ready for our morning date, darling"

"It's not a date" said Eric, prying his arm out of Grell's grip "I'm dating Alan, and your-"

"I know I know, dating Will" said Grell, finishing Eric's sentence "Just because I'm tied down doesn't mean I can't look at what's available" he grinned and once again attached himself to Eric's arm. Eric sighed and once again removed him,

"Grell, I'm flattered that you find me attractive, but I see you only as a friend, nothing more" he said. He smirked and headed towards the door "Besides, high maintenance isn't my type",

"High maintenance?" screeched Grell, running after him "I'm not high maintenance you cheeky git!". Eric laughed loudly,

"Calm down princess" he said "You may not be my type, but I like you just the way you are". Grell slowed down, his expression softened,

"Really?" he asked,

"Really really" replied Eric. Grell sighed happily and rested his head on Eric's shoulder,

"Thank you darling, that means a lot" he said. He sighed again and gently stroked Eric's chest with his fingers,

"Last night really was special" he said "It's a shame it wouldn't work between us". Eric stopped dead in his tracks,

"Let me make one thing clear" he said "As far as I'm concerned, last night never happened".
