It's the first sexual story I write so no flaming please! :)

"Where are you going?" Naoki and Kotoko just had dinner, and Naoki was now putting on his coat, looking ready to leave somewhere. "Oh, didn't I tell you? I'm meeting Watanabe tonight," He said, looking at his wife who followed him to the hallway.

"Watanabe-kun? Oh your old friend back in high school?" Kotoko asked with a nod. "Yeah, I haven't seen him in ages, so we decided to go drink somewhere tonight," Naoki said, his gaze upon the umbrella this time. To bring, or not to bring. "Oh.. but now that our parents and Yuuki are staying at your grandparents' place, I'll be lonely…" Kotoko said, poking her fingers together. "Then wanna come along?" Naoki asked, surprising her.

"No! No thanks, I'll stay here," Kotoko said in a hurry, shaking her head vividly. She absolutely didn't want to get between him and Watanabe. Like he said, it had been ages since they arranged a meeting, so it should be a men's night out. Naoki sighed and shook his head. "You don't make any sense. Well, bye." He hesitated, recognized her cute questioning eyes and then kissed her forehead before he left.

The door closed behind him and Kotoko sighed. Then she stretched her arms and let out a squeal. This wasn't too bad after all. It had been a while since she had been home alone, so she thought she'd go upstairs and take a relaxing bath!

Kotoko had a good time being alone. After the bath she watched a movie and read a few chapters in her book. By time she had done all that it was already past midnight, and Naoki still wasn't back yet. She was sitting on their bed, reading her book while listening to romantic songs on the radio.

"Hmmm..." She gazed at the clock and noticed that it was already pretty late. She thought to herself that Naoki might be home late, so she'd better go to bed already. She climbed off the bed and started to undress. While doing so she was singing along with the radio, making her unaware of the sound of the front door. She did notice when the door of the bedroom opened and she gave a shriek in surprise when she felt a hand on her shoulder.

"Ah, sorry Irie-kun, y-you startled me," Kotoko said, sighing with relief when she realized it was him. She had just pulled off the sweater she was wearing, and was now exposed in only a tank top and shorts.

"Irie-kun?" Naoki's face was a little flushed, and he seemed… different. Just as she wanted to feel his forehead - doubting whether he was drunk of ill - he staggered towards her and she felt how the weight of his body pushed her down on the bed. "I-Irie-kun? W-what are you-" Naoki pushed her back down when she tried to protest, pinning her down. "Iri-" He leaned in and she quickly turned her head with a gasp. Kotoko's neck caught the kisses her husband had aimed at her lips, sending shivers down her spine. Kotoko noticed how he smelled like beer and wait - whiskey? "

Y-you drank? Irie-kun stop it!" She tried to push him off but he didn't even move. He just continued kissing her neck, placing soft kisses down the sensitive skin. "I-Irie -" Kotoko stopped her attempt to call his name when he started to suck on her neck, leaving a few hickeys here and there. She squirmed and twisted under him. Naoki was drunk, was this what alcohol did to him? No way! Her attempts to move him off were helpless though. Had Naoki always been this strong?

"Irie-kun!" Her drunk husband now managed to press his lips on hers, and she felt how the kiss drew away her power to fight back. Eventually she just allowed his tongue to enter her mouth, allowing him to kiss her passionately. He stopped for a moment to move some hair from her face.

"Kotoko, I love you," He said as they both breathed heavily from the kiss. "Irie-kun, you should go drink some water..." Kotoko mumbled with a blush. She felt really shy right now. She wasn't used to confessions, even though he was her husband. The words 'I love you' from his side were rare in their marriage, she had learned to live with that.

Naoki ignored her water-suggestion and kissed her again, and Kotoko's eyes widened when she felt his hands move down. She squeaked when his cold hands touched her bare tummy as he moved his hands under her tank top. 'Not now!' She thought. She absolutely didn't feel like it. Especially now that he was drunk. He let his hands slide up her body until he reached her chest, and Kotoko moaned when he started to rub her breasts.

"Naoki.. don't!" She again tried to push him off. Naoki grunted and with one rough tug he took off her tank top. Kotoko squealed and turned away from him, crawling to the other side of the bed. She reached her arm over the edge of the bed to try and pull her over, but her drunk husband just wrapped his arms around her middle and pulled her back. "No, no, no! Irie-kun!" Kotoko shrieked as she was pulled back towards the beast that was supposed to be her husband. Kotoko wrestled with him, but Naoki reached under her and pulled down her bra with one hand.

"Aahh!" Kotoko buried her face in the blankets as she let a wave of pleasure take control over her. Naoki's firm hands were now fondling and massaging her breasts while his tongue left a trail of saliva and goosebumps down the back of her neck. Kotoko couldn't believe it, she didn't want it, but the little game they seemed to be playing was turning her on. Naoki flipped her body, and before Kotoko could meet his gaze he leaned in and attacked her chest with kisses. "I-Irie-kun stop it, please!" Again she was ignored, and she suppressed the sounds she was about the make when he started to fondle her breasts, while sucking on one nipple.

Naoki had never attacked her body like this before. Their other sexual actions were calm, controlled, and maybe a little to normal. A little bit of foreplay, the act, and a lot of cuddling afterwards from Kotoko's side. Just... normal. Right now was anything but. While Naoki still fondled her breast, Kotoko felt how his other hand reached around her, and she let out a yelp when he squeezed her behind. Meanwhile, his hungry mouth had switched to her other breast, arousing her by flicking the tip of his tongue over her nipple.

Kotoko had given up her attempts at escaping his clutches, and she had her arms wrapped around him now, burying her face in his shoulder to muffle her sounds. She felt so embarrassed. She arched her back when he slid one finger down her back in a teasing - ticklish - way, and then tried to protest again when his hands moved down and pulled down her shorts. "N-no Irie-ku-" He cut her off by kissing her roughly on her lips, his hand making its way into her panties. Kotoko squirmed but couldn't help but let out some moans of pleasure when he rubbed her. "Irie-kun!" She whimpered.

"Shhh..." Naoki hushed her and Kotoko moaned as two of his long fingers entered her. She covered her mouth with her hands, feeling embarrassed at the sounds of pleasure she was making. This had to stop, it felt good but it didn't feel right, he was overpowering her. She tried move in a sitting position, but Naoki pushed her back down, fingering her to the point that Kotoko couldn't help but cry out. He used his thumb to rub her clit at the same time, making her body shake and shudder with pleasure.

When she was close to the edge he suddenly grabbed her hips and lifted her bottom a little from the bed. "Naoki what are you-ahhh!" Kotoko reached down, only being able to grab a fistful of hair, but unable to stop him. He was licking her, circling his tongue around and inside her womanhood. That was a first. Their foreplay never went this far, but it felt damn good. Kotoko moaned in pleasure and covered her mouth again, as the ticklish but arousing feeling of his tongue continued.

He slowly started moving up, licking her body in the progress, making her squirm and whimper. She giggled when he licked her belly button and she wiggled her body a little. Naoki looked up at her and smiled. Kotoko smiled a weak smile as she took his face in her hands, feeling the heat of the skin of his cheeks. "Kotoko," Naoki sighed and he moved up to kiss her lips. He then pulled back. "Kotoko," He repeated, and with one quick motion he pulled off his own pants and boxers. "N-Naoki -" Before she knew it, he was with one thrust inside her. Kotoko cried out at this and wrapped her arms around him as he moved in and out of her.

"Naoki!" She moaned. He kept pushing in and out of her, their hips moving in sync. "Kotoko!" He exploded into her, and collapsed on top of her. They both panted and sweated, and Kotoko still couldn't believe what just had happened. While she was recovering from the things Naoki just did to her, her eyes slowly closed, and she fell asleep, with Naoki still on top of her.

Naoki awoke in the morning, noticing the curtains weren't closed and the morning light was entering their room. He then noticed he was on top of Kotoko. "Huh?" He backed away from her, taking some blankets with him as he did so. This revealed a part of her naked body, and he gaped at her in surprise.

He then noticed he was naked too. What happened? Kotoko was still asleep, her chest moving up and down as she breathed. Naoki took a closer look at her and spotted the hickeys in her neck. His eyes widened. He also noticed her breasts. They had hickeys and bite marks all over them. Naoki slowly took some more of the blankets away from her, a curious look in his eyes. There was no single piece of clothing on her body. But they never slept naked!

Naoki scratched his head. The last thing he remembered, was having a couple of drinks. There was beer, a lot of beer. And... whiskey? He wasn't sure. So that's where the blackout already started. At least he had been able to get back home in one piec. But... Kotoko's body distracted him, and he stole a glance at her naked body, allowing himself to think she was beautiful. He reached up and let his thumb caress one of the bite marks on one of her breasts. Before he could finish his wondering thoughts of how she got these. Kotoko's eyes opened. They stared at each other for a moment before Kotoko looked at his hand and swatted it away from her chest. "Kya!" She sat up and backed away, pulling at the blankets to cover herself up.

"What?" Naoki asked, raising his hands. "W-what do you think you were doing!" Kotoko yelled at him, face bright red with embarrassment. "I asked you to stop, but you wouldn't!" Naoki looked at her with a frown. "What are you talking about, you were asleep! You were asking me nothing! And all I did was..." Naoki blushed in annoyance and embarrassment. He touched her for a brief moment, so what was the big deal?

"Ohh, well you did more than that! And I was 100% awake! You drunk bastard!" His wife squeaked. "Drunk bastard?" Naoki was even more confused. He was drunk? What the hell was she talking about?

"Kotoko, what happened?"

"Don't tell me you don't remember!"

"No, tell me!"

"No I'm not gonna tell you!"

"Koto-" Naoki received a pillow in his face.

"Come on!" He crawled towards her which made Kotoko scream.

"Kyaa no I won't tell you!"

"Why not?!"

"It's embarrassing!" She hit him with the pillow once more, but he caught her hands and pinned them down. "So I did something embarrassing to you?" Naoki asked, moving closer and hovering over her. Kotoko gasped. He looked so hot. Even though it was morning, her husband was always sexy. From his ruffled hair to his muscled body. Kotoko blushed and nodded, making Naoki grin.

"What was it then?" Kotoko shook her head, she couldn't tell him! How embarrassing. Her husband suddenly shoved one arm under her, and wrapped his other arm around her so he had her caught in his embrace. He then let his fingertips circle around on her belly, making her bite her lip.

"There, I got you. Now tell me or these fingers might do their thing." What the hell Naoki? Those damn fingers already did their thing, Kotoko thought. But the moment he wiggled them all over her sides and tummy, Kotoko gasped and giggled softly. "I know how ticklish you are. So tell me?" He asked, and Kotoko shut her eyes tightly and shook her head again. "Hmm really?" His fingers moved down, teasing her thigh - dangerously close to her private part that he had ravished the night before. Kotoko shivered and still held back giggles.

"P-please stop it!" She squirmed in his embrace, sweet laughs escaping her lips. Naoki laughed at her. "Not until you tell me what I did to you?" His tickling fingers traveled up her sides, under her arms and towards her neck.

Kotoko couldn't hold back and started giggling like crazy, squirming around in his embrace. "F-f-fine hahahah you f-fucked me okay?" She laughed. "What? You're lying." He kept on tickling her, the jerk! "Kyahaha no I'm not hahahaa, you were drunk ahahand came in and heheh made love to me!" Kotoko managed to say between laughs. Naoki was shocked to hear this, she had to be lying, how could he have done such a thing and not remember it? Without noticing that his hand was still making his wife laugh, he gazed at the clothes on the floor. Had he turned into a beast? A monster?

Kotoko kept on laughing, until they both jumped in shock as the door opened. "We're home!" Mrs. Irie's head popped in. "THANK GOD!" Kotoko had wriggled away from him and jumped out of bed to greet mrs. Irie and Yuuki who already realized they made a mistake. "Oh my, Kotoko-chan you're…" Mrs. Irie covered Yuuki's eyes with her hand and looked away. That's right, Kotoko totally forgot she was completely naked.

"KYAAAaaaaaa!"

The End ._.
