A/N: Just a friendly warning: things get hot and heavy toward the end. Considering that is how this fic started life, you're all good with that.

Just like last time she'd been waiting for the result, Penny had been pacing nervously back and forth in their bathroom. Their getaway a little over a month ago had been an amazing experience and even though Penny had managed to not stress about getting pregnant at that time, ever since they'd gotten back Penny had almost constantly worried about disappointing Leonard and herself once again. It had caused her to snap at her friends and, even worse, her husband on several occasions over the last few weeks.

She really should apologize to everyone she'd lashed out at, Penny thought as she watched Leonard checking the stick and comparing it to the instructions carefully. It wasn't their fault that she had been so stressed. Stress was bad. What if she actually had gotten pregnant and messed it all up, all because she was so sure she still had not gotten pregnant? "Jeez, how long does it take you to see that I failed you again? Just say I'm not pregnant and get it over with already!"

Leonard turned his head. "Why would I say you failed me?"

Penny had to work to control lashing out even more than she already had. "'Cause thanks to me you'll never experience being a father." Frustratingly, Leonard put down the test and instructions and walked over to her.

"Penny, we've talked about this. My feelings for you won't change, just because we can't have children."

Penny sighed and melted into his embrace. "I know. I just really want to give you this. I know how much you want to be a dad, and I also know you'd be amazing."

"Listen," Leonard said softly. "I won't deny that I'd love being a dad, but don't ever think I'd resent you for not being able to get pregnant with me."

"I just want to give you what I know you want," Penny whispered.

"You do that all the time," Leonard assured her.

Penny chuckled. "I thought sex didn't count?" She sighed and moved slightly away from him. "Sorry I snapped at you. I don't really mind not being pregnant myself, really. I'm not even sure I'd be a good mom."

Leonard raised his eyebrow. "Really? I think you'd be an amazing mom. Plus, you're the only one of us who can scare off all the guys coming after our daughter if we had one."

Penny giggled. "I bet if we had a little girl she'd have you wrapped right around her little finger."

Leonard nodded. "Yeah, you'd probably teach her that, too."

Penny nodded. "It's a secret all mothers pass on to their daughters. 'How to wrap men around your finger and have them do your bidding.'" She sighed. "Thanks for saying I'd be a great mom."

Leonard grinned. "Sure. Just one word of advice: don't ever tell this one you said you'd be okay if they weren't conceived."

Penny blinked, several times. "What?"

Leonard grinned wider. "You're pregnant, Penny."

"Really?" Penny glanced down, not a single indication a little person was growing inside her. "There's a little Hofstadter in here?"

Leonard grinned as he walked out of their bedroom. Penny was currently in the kitchen, music loudly blaring. He had no idea how she had managed to get up before nine, considering their activities lasting well past four.

Rounding the corner he caught sight of her. Penny was of course always sexy. Whether she was wearing just some sweatpants and accompanying sweatshirt, a nice dress, or some lingerie, Leonard always found her sexy. But to him, she was at her sexiest wearing just one of his button-up shirts. Especially today as she was happily dancing and skipping around the kitchen.

Penny stopped mid dance, apparently having caught sight of him. Her smile grew and she skipped on over to him. "Good morning, daddy-to-be!"

Leonard happily accepted the passionate kiss. "Good morning to you, too, mommy-to-be."

Penny grinned widely, then turned around. "Shoot, don't want to ruin breakfast."

Leonard watched her rush back, taking an extra couple of seconds admiring the effect of momentum, causing his shirt to rise up with each of Penny's step, but taking just a moment longer to come to a stop and fall back down. Apparently Penny had once again opted for a no-panties-breakfast, as she had once called it. In Leonard's experience it was usually misnomer, as Penny nearly always combined it with a no-bra-breakfast. Either way, the no-panties-and-or-bra-breakfast always concluded in a mutually satisfactory manner.

Leonard followed his sexy wife and frowned. "Hey, it's not French toast."

Penny turned her head toward him and glared, though Leonard could tell it wasn't serious. "I can make other things, too."

Leonard raised his eyebrows at her.

"I didn't say many things," she responded. "I figured I should try do this, so I won't have to give our child the same breakfast every day."

Leonard grinned at the reminder of their pregnancy, mimicking Penny's grin as she said "our child." Leonard moved closer and, from behind, wrapped his arms around her midsection, his hands going over her still flat abdomen. "He or she will also have me to provide them with decent breakfasts."

Penny sighed, her head falling back against his shoulder. "Leonard, Honey, if you don't stop now, breakfast will definitely be ruined."

"We can always go out later," Leonard reasoned, increasing the rubbing of her skin, pressing himself closer to her, allowing her to feel his current state.

Penny moaned. "Later's'good," she agreed.

The next thing Leonard knew, Penny had turned off the stove, moved the pan off the hot section to the still cold section, turned around in his embrace - the single button Penny had bothered to close snapping off in the process - and her lips locked on to his.

The need for oxygen forced Penny to end the kiss, panting as she locked eyes with Leonard. She was so ready for him, she'd seriously contemplated pushing him against the fridge and hop up and ride him. But a moment later she rejected that idea; she wanted Leonard to be in control, really fuck her hard. Floor? Too cold and hard. Bed? Too common. Couch? Again, too common. Her eyes roamed over the apartment. Would the salon table hold them? If Leonard really got going, probably not; he had after all managed to break the frame on her bed, years ago.

Penny yelped in surprise as Leonard lifted her up and deposited her on the kitchen island. How was he going to manage that? She sighed when his finger caressed her folds first, before venturing inside her for a brief moment. The next moment his mouth replaced his hand and he began to lick her. Penny moaned with pleasure but after a few seconds she gently touched his face, trying to make his stop. "I need you to really fuck me, Baby." He looked at her with surprise. "I need it, Leonard. I need you to fuck me hard. Like breaking my bed hard."

He seemed to understand what she needed. "Where?"

Good question, one that Penny had not yet been able to answer.

"We don't want to break our bed," Leonard said. "But if we want to turn Sheldon's old room to a baby room, we need to get rid of his old bed."

Penny grinned. She was horny enough that even a reference to Sheldon couldn't prevent them from having sex. "I like that dirty little mind of yours, Dr. Hofstadter." She hopped off the kitchen island, Leonard's arms supporting her and preventing her from falling sideways. The little tug of his shirt against her shoulder blades as the halves were pushed backwards annoyed her and she removed the article of clothing, leaving it on the floor as her lips hungrily reached for his again.

This time she ended the kiss much sooner and moved out of his arms toward the little hallway leading to the bedrooms. She turned around at the corner, Leonard still standing in the kitchen watching her in awe. "Come on, handyman. We have a bed to demolish."

# # #

Leonard watched a completely nude Penny walk away from him, her perfect ass enticing him even more. She turned toward him and his gaze moved upwards, latching on to his 'breast friends.' He hadn't had an opportunity to see them earlier. They still jiggled a little from her turning around.

"Come on, handyman. We have a bed to demolish."

He grinned at her term for the activity they were about to engage in, and moved toward her as Penny remained in her place until he had almost reached her. She took two step backwards, Leonard watching in fascination as her breasts moved up and down and sideways a little. She then turned around and his eyes shot downward toward her ass, as he followed her to Sheldon's bedroom. Odd how the thought - or even the mention, earlier - of his friend didn't seem to have the slightest influence on his state.

Once they entered the room, Penny moved immediately to the center of the bed turning around to face him and beckon him.

Leonard realized he was still in his shirt and boxers, and got rid of them first, before climbing onto the bed toward his hot, sexy wife. Even though he knew Penny wanted to be fucked, he started with simply kissing and caressing her. He just needed to show her how much he loved her, that he wasn't with her just to have sex. Penny understood that, would always accept that it would start out that way, regardless of her wishes.

This time, Leonard took extra time on her abdomen. A baby was growing in there. Their baby. He kissed her belly button again and looked up into her eyes.

She smiled at him. "You should be proud, Sweetie. You disproved the Pauli exclusion principle."

Leonard frowned momentarily. "Well, technically that is not the case. One body is encapsulated inside the other, which is..." He noticed the look on her face and - surprising himself - smoothly finished with, "completely unimportant." He smiled at her and was glad to see her look revert to the one she'd sported before he decided to point out the error in her statement.

He remembered what Penny wanted and Leonard, sure he'd shown his love for her more than adequately and not wanting to ruin her mood by taking too long or - perhaps more likely - say something stupid, moved back up. He was going to give her exactly what she had said she wanted.

# # #

Penny was glad she'd managed to give Leonard a look he took as her being mad at him for disagreeing. That wasn't the case, really. She was well aware being pregnant did not disprove the principle. The fact was that Penny knew that letting Leonard talk science to her would get her motor running too hot and things would be over way to quickly.

She watched him move until he was on top of her, his dark eyes boring into hers at such intensity, she had to work really hard to not just grab his face and kiss him senseless. She wanted to be taken and from his movements, Penny thought this time he would actually go through with it completely. Kissing him would be counter productive at this point.

Both his hands grabbed her wrists and maneuvered her arms over her head, crossing them at her wrists. With one hand, Leonard restrained her arms, actually leaning on to her wrists and applying pressure. His other hand moved down and grabbed her leg, which he then moved up against his torso, pulling it tightly against him.

He let go of her leg briefly to line himself up, but once he moved the tip in between her folds, his hand grabbed hold of her leg again, pressing it against him with force. He then slid completely inside her in one swift motion and Penny moaned in pleasure. He gave her very little time to adjust to his invasion of her, and rocked back and forth soon after.

She felt his hand move down her leg and suddenly she felt her lower body being turned, resulting in one of her legs trapped between his, the other once again pressed tightly against him. With the pressure he had on her wrists, her upper body remained mostly flat on the mattress, her lower body at almost a ninety degree angle.

He immediately increased his pace, the hand holding on to her leg every once in a while moved down and slapped her on the ass. Good god, he really was giving it to her. Penny was afraid she was going to cum right away.

"Is this what you want?" Leonard growled, looking at her. "Being held down, slapped and fucked?"

"Fuck, yeah," Penny managed to get out, the combination of his forceful movements inside her, the regular slap on her ass and her being absolutely powerless to do anything about it, driving her to her climax, which came quickly. Leonard, however, did not stop.

"Couldn't control yourself, could you?"

Holy shit, Leonard really was getting into this. "No," she whimpered.

"You need to learn to control yourself. You can't cum until I say so."

Penny looked at him as he kept fucking her. His hand came down on her butt hard.

"Do you understand?"

Penny nodded and was rewarded with another slap.

"I can't hear you. Do." He slapped her again. "You." Another slap. "Understand?" Another slap.

"Yes," Penny tried to say, but it came out really quiet. Again he slapped her and Penny started to feel the stinging sensation.

"What was that?"

"Yes, Leonard. You tell me when to cum."

He grunted. "Good."

Penny closed her eyes as Leonard moved faster and with more force inside her. She could hear the bed move against the wall every time Leonard moved inside her, the rhythm helping her move focus on something other than what he was doing to her. If she didn't, she'd climax in no time at all.

"Look at me!"

Penny's eyes snapped open at his command.

He was smirking at her. "You're not having trouble already, do you?"

Penny shook her head, her eyes closing momentarily as he slapped her ass again. There had to be forming a bright red spot right now, but she couldn't care less.

"What's that?"

"N- no t- tr- trouble," Penny managed to get out. "Oh, God, yes!"

"Sounds like you are in trouble," Leonard said, every word interspersed with heavy breathing.

"Please, let me cum," Penny begged, feeling her climax closing in.

"Not yet," Leonard said, pumping inside her at a fast pace.

Penny waited for his okay, difficult as it was becoming for her. Watching him, she could tell he was fighting off his own climax, not wanting her to cum just yet. "Leonard," Penny whimpered, the coil inside her so tense she was afraid she'd explode. "Please."

"Soon," was his response. "Third time I spank your ass."

Penny nodded, hoping he'd do that swiftly. The first spank she saw coming, but the renewed stinging almost sent her over the edge. The second followed quickly after it, but then this hand moved back to her leg and he kept pumping inside her for a good while. She watched his hand as it moved away from her leg, anticipating the freeing final slap on her butt, but his hand merely pushed on her hip.

How the hell was he holding out so long? Penny was now certain she was going to explode, all he had to do was hit her ass. She looked into his eyes, silently begging him to allow her release.

Again he smirked, rocked inside her a few more times and slapped her ass one final time as he emptied himself inside her.

Penny released herself, not quite sure what came out of her mouth, but pretty sure everyone in the entire apartment building would be able to tell her next time they saw her.

# # #

Leonard collapsed onto the bed, his breathing whistling and going out of control. He needed his inhaler, which was in their own bedroom. He rolled off of Penny, allowing her to get it, but before he even was fully on his back, Penny pushed an inhaler into his hand. He quickly applied the medicine and allowed it some time to take effect.

Only then did he wonder where Penny had retrieved his inhaler from. He was reasonably sure she hadn't taken one with her, though he had to admit his focus had not been on her hands as they made their way into this bedroom. He looked at the inhaler and noticed it was the Spider-man inhaler he thought he'd lost a few years ago. Not that he had used it in the recent years before it went missing, but he'd kept it, because it had been one of the few times Mother had allowed him such a whimsical inhaler. He wondered if his Green Lantern inhaler, which had gone missing around the same time, was tucked away somewhere in the apartment as well.

"Damn, we didn't break the bed," Penny said.

Leonard chuckled. "I guess we'll have to try again someday soon."

"Mmm," Penny hummed. "But next time, I'll be in control."

Leonard smirked. "Like you were before?"

Penny giggled. "No guarantee about that. Damn, you did amazing, Honey. What I meant, obviously, is that next time you'll be helpless as I ride you into oblivion."

Leonard smiled as he stared at the ceiling. His wife had often proven she was capable of doing exactly that. He held her as lay half on top of him.

"Leonard?"

He hummed, unsure if he'd actually dozed off, or was just on the way.

"What if it's boy?"

Leonard looked at her. "Wha- do you not want a boy?"

"No, I meant, earlier, you talked about us having a girl and I'd be the one to scare the boys away. What if we have a boy? One who's as smart as you are? What would be my job then?"

Leonard grinned. "Simple, scare the bullies away."

Penny propped herself up on one arm. "I can tell you right now, if our kids are being bullied and the school doesn't do anything about it, I'm gonna raise all kinds of hell. Our kids are not going to be subjected to any kind of crap like that."

Leonard grinned again. "Already thinking about getting another kid, are we?"

Penny shrugged. "Why not? Though I draw the line at three."

Leonard nodded. "Three seems about right to me, too."

Penny smiled. "Good. Now, I'm gonna take a shower and then we can go out to get something to eat. Will you join me?"

Leonard scoffed. "A shower with my sexy, pregnant wife? Of course I'm gonna say yes to that!"

Penny giggled again, planted a kiss on his lips and moved away.

Leonard moved into a sitting position but caught sight of Penny's left butt cheek. "Oh my god, it's so red!"

Penny glanced down, twisting to see the result. She grinned and nodded. "Told you, you did amazing."

A/N2: This completes this one-shot-that-wanted-to-be-more. In the future I may look into Hofstadter babies in a different story. Thank you to everyone who read and/or favorited this fic, and an even bigger thank you to those who took the time to leave a review.
