A/N: Hello (mature) boys and girls. I finally got 'round to writing a sequel to The Playtime Experience. After all, Leonard still has to decide on which outfit was the most sexiest, and he can't do that without having repeatable results. And neither participant seemed to have any objection to that. Based on reviews on Playtime Experience, neither do you guys.

It goes without saying that I do not own BBT, and I do not make any money with this whatsoever.

Penny smiled at Leonard's reaction to seeing her standing at her bedroom door, her right arm stretched up high, hand braced against the door frame. She had put on the dark blue nighty she had bought a few weeks ago, the one that had initiated three nights of ever increasing passion. She had added a new pair of heels, having remembered Leonard's preference to seeing her in lingerie and high heels. "Hey, you," she said, her own arousal coming through, despite trying to sound casual. "How are you doing?"

Leonard visibly swallowed, his eyes traveling over the entire length of her body from the tip of her fingers stretched high above her, all the way down to her feet. "I was having a crappy day, but I think things are about to pick up."

"I don't know, Loverboy. You'll be working hard to repeat an earlier experiment." She frowned slightly at his little smirk, then grinned as she realized the emphasis on the word could be taken differently. "But, if you had a crappy day with all your experiments, maybe we should postpone this one?"

"No no. It was the experiments that were crappy, not my work," Leonard hastily assured her.

Penny looked doubtfully at him. "Are you sure, Loverboy?"

Leonard nodded, then a grin formed. "Besides, we can always redo the experiment another time if it turns out my performance was lacking."

Penny giggled. "Hmm, that sounds like an acceptable solution." Of course she knew Leonard's performance was never lacking, but there would no harm in pretending it did, so they could repeat it again later. "Do you like the addition of my new heels?"

Leonard nodded, even as his eyes were traveling the full length of her legs. "Yes, but this change will invalidate the earlier results."

Penny frowned. "I see. Should I take them off?"

Leonard shook his head. "No, it just means we have to repeat this particular experiment again, with the heels."

Penny smiled, glad that there definitely would be a repeat. Her smile widened when Leonard disposed of his clothes faster than she'd ever seen him do. She unconsciously licked her lips when his boxers were pulled down, his penis already hard and pointing straight at her. She wanted to comment that her heels clearly hadn't made a negative impact, but all the came out of her was a sigh when Leonard had pressed himself against her, his mouth immediately finding the sensitive spot on the side of her neck. Like the first time she had this nighty on, Leonard seemed to enjoy feeling the material against his naked skin.

She moaned again when one hand went behind her back, on top of her nighty, while the other went between her legs, gently rubbing her clit. She was glad Leonard held her tightly, or she would've fallen to the floor, her knees to weak to hold her up. His mouth had moved away from the side of her neck, traveling toward the center of her chest, her heels allowing Leonard to easily reach it with having to bend down too far.

The fact that his mouth was no longer on that sensitive spot on the side of her neck didn't change her desire and arousal, because Leonard's finger started to slide in between her now wet folds, his palm still rubbing in tiny circles against her clit. She knew her nipples were now rock hard, trying to pierce through the material that was still covering her. "Leonard," she said in a whispered sigh.

He glanced up at her and she could see the desire in his eyes. She wanted to kiss him, but instead let her head fall back in her neck as Leonard inserted two fingers inside her, reorienting his hand to allow his thumb to rub her clit. Her muscles tightened involuntarily around his fingers, her release almost there. Her hands had linked behind his neck, mostly to support herself, his simple ministrations making her weaker than she ever felt.

Leonard's hand moved from her back to the front, gently kneading her left breasts, his thumb lightly flicking her nipple through the material. He moved his hand to lightly tweak the nub between his thumb and finger. It was enough to send her over the edge, screaming his name.

Lying on the bed on his back Leonard watched as Penny, each leg on either side of him and her still wet core on his abdomen, slowly lifted the nighty up, exposing her beautiful body to him inch by inch, his eyes eagerly traveling along. As hot as she looked wearing that nighty, it was nothing compared to seeing her fully naked. Every inch of her body could turn him on. Her eyes, nose, lips, neck, shoulders, he couldn't see any part that he didn't find extremely sexy. As his eyes traveled along her body, his eyes noticed she still had her heels on, and a thought entered his mind. "Penny, would you stand next to bed, please?"

She frowned slightly but when he added another "please," she smiled, gave a small nod and moved off of him to stand right next to him. Leonard propped himself up to better see and experience the effect of his naked girlfriend, wearing nothing but those heels and a soft smile. "You're so beautiful," he said in a whisper. "I'm so lucky to have you in my life."

He moved to sit on the edge of the bed, allowing his hands to roam over her body. Penny responded by moving closer and putting one foot on the bed, next to his thigh. Leonard's hand immediately went to that leg, stroking her calf. He turned his head to kiss the side of her knee, then started a trail of kisses on the inside of her upper leg. As he was doing that, he moved both hands to grab hold of her bum, pulling her a little closer just as his mouth reached her entrance, the smell intoxicating him.

Penny's hands were now on his shoulders in a clear bid to stay upright and not collapse right there and then. Leonard's tongue darted inside, causing Penny to moan loudly. His main goal for the rest of the evening was to get her to climax as often as she could stand, to reward her for loving him and all his faults.

Penny's hand were now behind his neck, her fingers gripping his hairs as she pulled his face even closer to her groin. Leonard got the message: she was already close again and wanted him to taste her release, an activity he had no objection to whatsoever.

Penny collapsed on the bed, no longer able to keep standing, despite Leonard's hold on her. Experience told her that he had only just started, that she would experience a few more of these climaxes before they would finally join. She didn't mind tonight; in fact, she had hoped Leonard would be in the mood to proof he was worthy of the title 'King of Foreplay.' They hadn't had sex in the past five days because of Leonard being so busy with work that he'd usually come home very late, too tired to do anything but fall asleep.

Five days without sex. Pretty much five days too many, as far as Penny was concerned. Except for her very first time, Penny had always enjoyed sex. The very first time, she really hadn't been ready for it, and if she was honest, a bit too young. She had agreed because she hadn't wanted to lose her then boyfriend. She'd quickly found out that having sex with her was the only thing he had been interested in. It had taken her almost a year before she found herself ready to try again.

But that was a long time ago. It was the recent past that had bothered her more than she had thought it would. She completely understood Leonard not being up for it; if it had been her working as hard as he had been, she probably wouldn't have been up to it either. But she had been really glad when he told her this morning that he'd be home early; and he had been, even managed to snuck in a little nap before supper. That was a bonus as well, Penny realized; the nap would ensure he'd have plenty of energy for the evening's activities they had only started.

She giggled when his hand caressed her abdomen, his touch so light it tickled. He followed it up by a kiss on her shoulder.

"I didn't wear you out, did I?"

She turned her head to look at him, grinning. "Nope, just needed a short break. I really hope you're not done yet." She glanced down as Leonard did and smirked. "Clearly the answer is 'no.'" Leonard suddenly moved one arm under her knees, the other around her neck and then lifted her to move her completely onto the bed, placing her head on the pillow.

Despite his insistence on not being physically strong, these little displays clearly proved otherwise; it always aroused her and tonight was not any different. He smirked at her when he noticed her now rock hard nipples. His index finger gently stroked against the left one, barely touching but following the contours from the base, over the peak and back down the other side. The sensation combined with the contemplative look on his face made her shiver, knowing he was planning on something that would undoubtedly bring her next climax. She frowned when he placed a soft kiss on her belly before climbing off of the bed with nothing more than a commanding 'stay.'

Leonard walked back to Penny's bedroom but stopped near the door. "Close your eyes," he said, with a commanding tone of voice, despite feeling uncomfortable to use it. At her almost immediate response that her eyes were closed, he entered her bedroom.

"You should get the blindfold," Penny suggested almost immediately when he stepped inside. "And maybe you should tie me to the bed?"

"Blindfold it is," Leonard added, ignoring her other suggestion, mostly because he didn't feel too comfortable to do that to somebody, especially somebody he loved. He walked over to where he knew she kept some of the more kinky toys, most of which he rarely used. He grabbed the blindfold and walked back towards the bed to put the blindfold on her.

"Baby, you know I like being tied. It adds something to... well, whatever it is you have planned. I trust you."

Leonard looked at her, the blindfold already in place. She had moved her arms above her head, crossed at the wrists, and her legs spread wide. "Alright," he said after a few seconds, deciding that she apparently really wanted this. Once he had tied her to the bed, he grabbed the item he had temporarily placed on the nightstand. He grinned at the gasp she emitted when she felt the contact.

She squirmed slightly. "What's that," she asked, sounding curious but not worried.

Leonard licked the substance from her skin, then held it against her lip, pushing in as she opened her mouth slightly, allowing her to taste it directly from his tongue.

"Hmm, whipped cream."

"Yep. I noticed earlier you had some lactose-free stuff. Unfortunately, you won't be able to taste any more of it." He moved away from her face and drew a line of whipped cream from her throat to the center between her breasts and placed the container back on the nightstand. He then position himself between her legs and bend over to put his face between her breasts, licking a little bit of the substance off of her skin. He swallowed it and started to kiss his way up to her left nipple, sucking on it as he reached the peak. He kissed his way back down, licking a little more whipped cream as he reached the valley in between, his head now oriented sideways to continue dragging his tongue along her right breast, pushing the whipped cream against her nipple, then closing his mouth over it he sucked it in.

He didn't fail to notice the slight squirming taking place, and he put one hand on her hip as he scraped his teeth along her nipple. He kissed his way back to the center and started licking his way to her throat.

She was close again. Being blindfolded and tied took Leonard's already amazing foreplay to an even higher level. She swallowed as he whispered in her ear to hold it in a little longer, not sure if she could manage. She heard the sound of whipped cream being squirted out of the can and moments later Leonard's fingers applied it to her folds, one finger slipping inside slightly.

Then his mouth descended on her, slowly licking the whipped cream, undoubtedly mixed with her own juices. "Oh, God," she moaned when his tongue moved over her clit, nearly sending her over the edge. "Fuck, Leonard," she said, panting heavily. "I don't think I can hold it in much longer." Frustratingly, Leonard decided to not heed her warning, and continued in the same slow manner. Finally, his circle completed, his tongue dipped in slowly, his thumb rubbing her clit. Penny gave up trying to hold off her next orgasm, releasing it while screaming, "oh, God, yes!"

Once she had recovered, she heard Leonard use the can of whipped cream again while telling her she would get to taste some more, despite his earlier assurance she wouldn't. She opened her mouth a little and the tip of Leonard's whipped cream covered erection slid pushed against the small gap between her lips. Penny opened her mouth wider when she realized it wasn't his finger as she had expected, allowing Leonard to slip his erection inside further. Too soon he retracted, saying she got the whipped cream off. Clearly he wasn't looking for his orgasm yet, and Penny shivered again when he put a little bit of whipped cream on the sensitive spot on the side of her neck.

The feeling of his lips, tongue and breath on that spot immediately turned her on again. Leonard's thumbs were circling her nipples, every now and then stroking across them, as his fingers gently kneaded her breasts. She could feel her next orgasm approaching fast, but all of a sudden his touch disappeared, and she whimpered at the loss of contact. Then she felt his hands again, slipping in between the mattress and her butt, gently squeezing, his mouth placing kisses on her breasts, paying extra attention to her hard nipples.

She moaned as he slid inside her, setting a slow pace. She wanted to put her hands on his back, momentarily having forgotten she was tied hands and feet. She groaned softly as Leonard deepened his stroke, the feel of his full length going in while in her current tied up position bordering on painful. Briefly she was reminded of her very first time, with the three year older boy who had not cared about her pain and simply pounded on and on, covering her mouth with his hand to prevent her screams of pain from being heard by anyone. But this was Leonard; he loved her and he was being gentle, didn't pound into her mercilessly.

"Do you want me to untie your legs?"

She could imagine the concerned look on his face and she shook her head. "No," she replied. "I'm okay. Keep going, baby." It took a few seconds, but Leonard resumed his pace, only every now and then stroking deep, and Penny let herself enjoy the feeling of her boyfriend making love to her. "God, Leonard, I'm so close," she said.

"Good, I'm almost there."

Penny moaned as his pace increased, his strokes going deeper again, but it no longer brought pain, just pleasure. "Oh, God. Yes. Yes. Oh, Leonard. Yes!" Leonard kept going, faster and faster until he finally came inside her, collapsing on top of her. She wanted nothing more than hold him, but she was still tied. She noticed Leonard leaning over, then heard him use his inhaler. Finally he removed the blindfold and started to untie her. "God, I so needed that," Penny finally said as turned sideways, facing him. She bit her lip, then looked at him. "Leonard? Is it okay if I take off the heels now?"
