Okay! So this is my first shot at fanfiction, also my first shot at smut! I have been reading here for a while and noticed there was a real lack of Penny and Leonard stuff, so I gave it a go. Any reviews you have to give are greatly appreciated. Hope you enjoy!

Also I don't own any of this, bummer.

Leonard was sitting at the breakfast bar, reading the latest instalment of 'Scientist Quarterly'. He was alone in his apartment, Sheldon was at the University, determined to solve a problem he had been working on with Raj. They had called and said they would return to the apartment later on with dinner, and Leonard figured they would bring the rest of the gang with them too. He looked forward to it as he was starting to get a little peckish. He wondered if Penny was working today, and if she would be joining them. He went to go into his pocket to text her, but as if she had been reading his mind, she came bouncing in the door. "Hey sweetie!" She said as she skipped over to the counter and jumped to sit on top of it, just beside him, and then gave him a quick kiss on the lips. "Wotcha doin?" He smiled at her, he loved it when she was like this, so enthusiastic and bubbly. "You seem to be in a very good mood today!" He said, she nodded emphatically and he continued. "I was just reading , waiting on the guys to get back with dinner. So what has put you in such a good mood?"

"Oh I dunno, "She said as she leaned on her hands and swung her legs, "Maybe I just realised I'm a very lucky girl!" She smiled and looked through his glasses into his big brown eyes.

"Oh really?" He said, raising an eyebrow and got up off his chair to stand in front of her, he put his arm around her waist as she spread her legs, allowing him to get closer to her. Penny wrapped her arms around his neck. "And why is that?" He tiptoed up to kiss her on the lips, she was a little taller than she would usually be because she was sitting on the high counter top, but not so high that he couldn't reach her.

Penny bent down a little so he didn't have to stretch up too much, and then broke apart so she could speak. "A few reasons..." She began. She felt Leonard move his mouth to her neck, he kissed it lightly as she spoke, making it hard for her to concentrate on what she was about to say. "First of all, I am finally starting to understand all of the stuff the professor in college in talking about, which helps a lot!" She could feel Leonard smile against her and say "that's good." Then he got back to kissing her neck. And so is that… She thought as she closed her eyes and curled her toes. "Second of all, I made really good tips today in the Cheesecake Factory, turns out it isn't that hard to be a good waitress if you actually try!" She heard him giggle against her neck, sending shivers down her spine, "And third of all, as if all that wasn't enough, I get to come home to you…" She lifted his head up and captured his mouth with hers. She had been looking forward to seeing him all day. He was the reason that she had done so well in work today. She had had a rather naughty dream about him the night before, so when she woke up she was so horny that she almost went over to his apartment and jumped on him right then, but she knew she had to work, and so did he. So she waited, and just thinking about what she was going to do to him when she got home had put her in the best mood possible. She was snapped out of her daydreaming when he lightly bit her bottom lip. She pulled him closer to her, grabbing his head with both hands and running her fingers through his hair. She moaned into his mouth as his tongue danced with hers.

They continued to kiss passionately for a few minutes. Leonard pulled away and headed over to the front door to lock it, he really didn't want any of the gang to burst in and see what they were about to do. Leonard quickly returned to Penny, put his hands on her hips and pulled her as close as he possibly could to him. He felt her tighten her legs around his waist. He moaned and slid his hands down her body, gripping her thighs. She tickled the back of his neck with her fingers, while the other hand continued to run through his hair. Leonard could feel his pants tighten around him, making her effect on him clearly known. She moved her hands down his body and pulled up his t-shirt, the need to feel his skin on hers was overwhelming. They broke apart briefly to allow his t-shirt to come off, she threw it to the side and he latched his mouth on to her neck. She groaned into his ear as he lightly bit and sucked at her neck, making his way down her collarbone. He slid his hands back up her leg and up her t-shirt, stopping when his hands were on her side, just below her breasts. She shivered and sighed as she felt his warm hands on her bare skin. He removed his hands from her body, which she wasn't happy about, until he bunched up her t-shirt and pulled it off of her, revealing her black lace bra underneath. Leonard couldn't help but stare, it was a sight he had seen many times before, yet each time felt like the first. The fact that her breasts were eye level with him because of her being on the counter didn't help matters much. Penny noticed him staring and smiled, she loved that he so obviously adored every part of her body. She arched her back, pushing her chest further into his face, sighing loudly as she did so. Leonard pushed his face between them, and began kissing and licking her cleavage.

"Mmmmm." She moaned, biting her lip. Leonard saw her do this, he could feel his heart thump against his chest, she was driving him crazy. He moved his hands down to her waist again, as he kissed and licked his way down her chest, to her stomach. Penny leant back and rested herself on her elbows. Her breath quickened and she gasped as he manoeuvred his tongue down her body and into her bellybutton. He tightly gripped her left thigh with his hand, using his right to undo the button on her jeans. He kissed the flesh that was revealed and as he pulled the zip down he spotted her black panties that matched her bra. He looked up at her, and watched as her chest moved up and down with each breath she took, her head was thrown back, and her eyes were closed. He once again, found himself staring at her for a few seconds longer than he ought to. Penny noticed that he had stopped kissing her and pulled her head up, locking her eyes with his.

"Everything okay baby?" She asked him softly as she panted, unable to catch her breath properly. He smiled and nodded, before turning his attention back to her jeans. He had to get them off of her. He pulled his glasses off and placed them on the table, then began to pull her jeans down. Penny lifted her bum off the table as he slid the material down. Once they were fully removed he threw them to the side. His throbbing erection had tightened his pants around him, making it slightly uncomfortable, so he unbuttoned them to ease the tightness, however he didn't remove them. He didn't need to yet.

Leonard returned to Penny and began kissing his way up the inside of her leg, casually switching from one leg, to the other as he made his way up. Penny lay her back down fully on the table, relishing every kiss, lick and bite he gave to her body. She found herself moaning uncontrollably, completely immersed in what he was doing to her. Leonard continued on his quest up her leg, he made his was up her inner thigh, giving a quick bite when he reached the highest point. Penny moaned and ground her hips towards his face, begging him to taste her. He smiled, knowing the effect he was having on her, and loving every minute of it. He skipped past her sensitive area and began to kiss her stomach. He felt her hold onto his head and begin to push him down, but he stayed where he was. Penny let out a frustrated moan, "Leonard… Please…" She said between breaths. Leonard contemplated continuing his little game, and he would have if he had not known that his friends could be back any minute. So he gave in to her pleas, and with one hand he pulled her panties off, with the other hand he gently rubbed her sensitive spot with his thumb. He circled his thumb around her as Penny arched her back and yelped at his touch. He then lifted her legs on to his shoulders, before sliding his hands down her thigh to gently grab her ass. He moved his head between her legs before using his tongue to caress her area. He flicked at her clitoris then moved his tongue down and inside her. He moved his tongue out and licked his way around it, before entering her again.

Penny writhed beneath him, yelling, and grabbing at his hair. He always knew the right thing to do, he really was a genius. She thrust her hips against him, needing to create more friction. She felt him move his tongue up to her clitoris and began to swirl around it. "Oh GOD!" She yelled. Her breathing was erratic and her body had a mind of its own as it moved and twitched at every lick and every bite. Leonard moved his hands a little so that his thumbs were on her hip bone and held tightly, keeping her in place as he worked his magic. He moved his tongue around her, deviating between hard licks and soft kisses. He knew she was close, she was moaning constantly, saying things that were incomprehensible. All he could understand was "Oh God," and "Leonard." Not that he was complaining. Penny was in another world as she felt the waves of climax near. He continued to suck on her as the orgasm hit her like a tsunami. She screamed his name as she came and pulled at his hair as it was the only thing close to grab onto.

Leonard looked up at her as she caught her breath and smiled. He had done well. He pulled her up so that he could kiss her on the lips, stopping momentarily to look deep into her beautiful green eyes. "I love you." He said to her, almost in a whisper. Penny smiled and bit her lip before kissing him passionately once again. He had to move this into the bedroom!

Then suddenly, as he was about to lift Penny off the counter and take her to his room, there was a bang at the door. Someone was trying to get in. "Shit!" They said sounding both panicked and frustrated. Leonard quickly gathered up Pennys clothes, throwing them at her one by one. She jumped off the counter and put her clothes on as she quickly made her way to sit on the chair. Leonard threw his t-shirt on and zipped himself back up, returning to his seat at the breakfast table, just as Sheldon, Amy, Raj, Howard and Bernadette entered the apartment. That was close! He thought as he looked over at Penny, certain she was thinking the same thing. Sheldon moaned at the fact the door was locked, saying it made no sense to have it locked if there was already people inside the apartment. Leonard dismissed his comments, he knew by now it was easier to accept it than to argue with it. Leonard sat at the breakfast table for a moment, thinking back on what had just happened, deeply disappointed that he hadn't got to the bedroom before his friends came back. And then for the second time that day, Penny read his mind. His phone beeped and he grabbed it off the table and read the text. It was from Penny.

"Don't worry baby, you will be greatly rewarded tonight at my place for your brilliant work here today. I love you. Xxx"

A smile spread across his face, he looked up and caught Pennys eye, she discreetly winked and bit her lip at him. This was going to be a long dinner.
