He was pretty sure she had seen his wedding ring. But it didn't seem to matter to her because he was now at her apartment and inside her. Oh God damn, she felt so good. So wet. So tight.

All his years of marriage, he had never cheated on Kathy till tonight. And somehow it felt liberating.

She moaned from under him as he started to thrust in and out of her. "Oh God, Chris. Your cock feels fucking good. So big!" He had not given her his first name. Instead he had shortened his middle name.

What he didn't know was that she had done the same thing. She knew this was a one night thing. And she saw the wedding ring. But she didn't care. Not that night. He was too handsome and she was too horny. So she had brought him home and told him that her name was Grace. Which it was and wasn't. It was her middle name and no one called her that.

Suddenly she flipped them over and she was on top. She grabbed his hands and put them on her breasts. He took the hint and he pulled the hardened nipples with his calloused fingers.

She moaned and she rode him harder. She ground her pussy against his pelvis, and then clenched her vaginal muscles voluntarily making him gasp and shout. "Grace! Do that again! Please!"

A mischievous smile came upon her face and she began to go up and down his hardened shaft. Christ, she was glad she chose him tonight. She had never had a man as big as him. Or as long. He had to be at least 8 inches and THICK.

When she was going down on him earlier, her fingers barely met around his cock. And she almost gagged as she took his cock down her throat. And now he filled up her like no one has before. It was good thing he was married. Because aside from being well endowed and good in bed, they had a fucking great conversation prior to fucking liking rabbits. If he hadn't been married, her heart would be in danger she knew.

She squeezed his cock again with her pussy and Chris moaned in response. He released her breasts and his hands quickly went to her ass, one of them slapping her ass cheek soundly. Grace gave a little yelp but then the slight sting only managed to make her more aroused and wetter.

She started a faster rhythm, grinding her pussy relentlessly against his cock.

But then just as she was feeling her edge come closer, Chris flipped them over again and suddenly he was the one straddling her. A moment later he pulled out and Grace protested. "What the fuck?"

He chuckled and replied, "Relax baby, we're going to finish – both of us. But right now, I want to fuck you doggy style. Is that okay?"

She nodded and gave him a sexy smile. "Sure." And then without needing instructions from him, she went on her fours and wiggled her ass for him.

The next she thing she knew she was being pummeled from behind. She was also so wet that she could hear the wet sounds of him going in and out of her as well as his balls slapping against her. One of his hands grabbed her hair while the other went on one of her breasts, pinching the nipple yet again.

She whimpered loudly. "Fuck! That feels so good! I am so close, baby. Fuck me."

He grunted from behind her and pushed her gently down making her lie down practically on her stomach. The position made it only tighter for him inside her and he could feel his orgasm nearing when his cock twitched.

She was getting close too. He could tell because her pussy which was so wet suddenly clenched around his cock again. But then all at once he pulled out again and quickly turned her over. He opened her legs wide and with one thrust, he rammed his entire length inside her that she gasped.

They were looking at each other now. She gave a little gasp when she saw the unadulterated lust that was surging in him through his stark blue eyes. At the same time, she could tell that he was feeling something beyond lust. But right now, she didn't want to analyze that, she just wanted to drown in those beautiful blue eyes and she just wanted his cock to keep ramming her.

Wow! He thought. She had beautiful eyes. Suddenly, he wished he wasn't married. He had fun with her at the bar. Great conversation and everything. And, God, this fucking great sex too. Better than he ever had with his wife, that's for sure.

She moaned and whimpered loudly once more and he felt her pussy spasm. He gasped. That feeling of her squeezing his cock inside her was absolute heaven.

He grabbed her legs and put them on top of his shoulders. Once again, what was tight was made tighter and suddenly all other thoughts flew from his head. Right now all he could think of was how hot and wet her pussy was and how it felt good inside her even with a condom. He could just imagine how hot and even better she would be bareback.

"Baby…" She whimpered, "I'm so near, fuck me. Fuck me hard."

At her words, he started to thrust harder, faster….her hands that were on his ass began to grip his cheeks harder, her fingernails digging into his skin there. That slight pain only made his movements more frenzied.

"Shit, baby, your pussy's fucking tight."

"And your cock's so big and hard. I love it! Fuck me, I'm so near, Chris."

He took one of her legs down and then getting on his knees, he continued to thrust in and out of her while one hand traveled in between them and found her swollen clit and began to rub it.

She bit her lip as pleasure flooded her entire being. The man was a fucking sex god, damn it. Then suddenly he was crying out loud and she was crying out loud, her pussy started to clamp and pulsate around him as her orgasm crashed squeezing his cock, milking it, driving him to his nirvana. She could feel his cock's every twitch - his cock was spurting his seed now. She could feel him cumming hard and she knew that he must have spilled a lot of semen because his orgasm lasted a long time. Almost as long as hers.

When their orgasms waned, Chris collapsed against her. And then before he could get soft, he pulled out of her. After a few moments, when his breathing normalized, he peeled off the full condom off of him and stood up. He motioned to her and asked, "Where should I dispose of this?"

"Bathroom." She told him, smiling.

"Where is it?"

"That door in front of you."

"Okay. Do you mind if I wash up as well?"

"No problem. Towels are on the cabinet inside, just grab one."

"Okay thanks."

She watched him go to the bathroom and close the door. As he was inside, she also got dressed and grabbed a bottle of beer from the fridge. When she came back, he was done and was already wearing his jeans.

She glanced at the clock. It was nearly midnight and she had an early day tomorrow. As great of a fuck he was, she needed him to get out now.

"So I hope you don't mind if I don't ask you to stay." Her brown eyes met his blue ones.

He smiled and replied, "No it's okay. I gotta get home."

"I noticed." She returned pointedly, giving his wedding ring a knowing stare.

He saw where she was looking and his face suddenly went red. "Uh, I.."

She laughed. "Don't worry about it. It was one night. It was great but let's not pretend this is something it's not."

He felt a little disconcerted at her words, but again he realized that she was just saying the truth. And besides even if she intrigued him and they had a fantastic time earlier even without the fucking, she was right, he was married.

"I've never done this before." He told her truthfully.

She gave him a smile that could only be described as cynical and replied, "If you say so, Chris."

"I'm serious, Grace. I've never done this before." His tone was suddenly serious, like he really wanted to make her believe him.

She searched his face and found nothing there but sincerity. Maybe she was tired. Maybe because he fucked her so well she wanted…needed to believe him but she did believe him. So she nodded and said, "Okay, Chris. I believe you. But let's not make this complicated. I had fun. You had fun. That's it."

"Yeah, that's it…" For some reason even though she was only speaking the truth, he felt let down.

"Well, hate to do this to you, but I have an early day tomorrow. It's my first day in my new job so I can't be late. I gotta get some sleep. Thanks for the great sex."

He was dressed by now and he laughed. "Same here, Grace. Thanks."

"Thanks Chris, bye." She returned, standing up and walking him to the door.

There they shared one last kiss and then he turned around and left. As she watched him leave, she felt a twinge of regret. Why were the good ones taken? She sighed and finally closed the door.

He waited for the elevator to come and as the doors opened, he took one last look at apartment 4D and felt a pang of sadness. Part of him wished this wasn't just a one night stand. But it was and he had to accept that. He knew that he would never see her again. As the elevator doors closed, all he could do was sigh in regret and sadness.

"You what?" Munch exclaimed loudly. It was morning and another day was beginning in the 16th precinct.

Elliot had just told Munch that he had cheated on Kathy and slept with a hot chick the night before.

Elliot shrugged and ran his hand through his short cropped hair. "I've never cheated before this John. But man, she was just driving me crazy yesterday and so I went to this bar and the next thing I know I was in this girl's Upper West Side apartment and we were fucking each other's brains out."

Munch began to grin and replied, "Well St. Elliot isn't so saintly after all. I'm glad to hear that you're not as moral as you so moral as you seem to be. So how was the sex?"

Elliot looked at the older detective and replied, "Oh my God it was fucking incredible John. Kathy…Kathy is so freakin' inhibited, this one wasn't. Man, if I were the type to have an affair…"

"But you're not." John interjected.

"No, I'm not. Anyway…I'm never going to see her again. I mean I didn't even give her my real name and plus she saw my wedding ring."

"Well then that's good, she won't be able to stalk you…"

"I highly doubt that she's the stalking kind…."

"Stabler!" Captain Cragen called him.

"Yeah, Cap."

"Come here and meet your new partner, will you?"

"Oh here we go." Elliot rolled his eyes, looking a Munch. "How long do you think this one is going to last?"

Munch snickered. "Well maybe if she's gorgeous, then hopefully a while."

"Fat chance. And besides how did you know it would be a she?"

"Stabler, now!" Cragen called out to him again, looking annoyed at the delay.

Elliot glance at Munch and Munch answered, "Because he told me. Get your butt over there, before he has to call you a third time."

Elliot rolled his eyes again and then muttered, "Here goes nothing."

He stood up and entered the Captain's office. "You wanted to see me, Cap?" Elliot said, closing the door behind him.

A woman was sitting on the chair in front of his desk, but Elliot barely glanced at her.

"Yeah, Elliot, I'd like you to meet your new partner," he motioned to the woman on the chair who now stood up and faced him, "Olivia Benson. Olivia Benson, Elliot Stabler.

Suddenly the world stopped. Not just for Elliot but for Olivia too. They could not believe their eyes, and it was all they could do from gasping and asking a million questions.

In front of Elliot was Grace – the woman he slept with last night. Only she wasn't Grace, she was Olivia Benson. His new partner. His new partner the woman he had slept with last night.

What was he going to do now? What were they going to do now? And suddenly what had been a one night stand no longer was just that. Suddenly it was complicated.
