A/N: Here's Sundays activities. There might be a Monday morning short chapter following. Not entirely sure yet.

Don't own anything but Kirstie. Also, don't make any money with this. I'm just a poor boy, nobody loves me :D

Leonard had been slightly apprehensive at Kirstie's suggestion; he didn't particularly like being blindfolded, not even when it was just him and Penny. However, Kirstie had told him it was going to be a fun game, and they'd all be enjoying the game she had in mind. So, reluctantly, he had agreed to be blindfolded, a task that had been given to Penny, much to his relief. Penny had whispered, "I love you" as she tied the blindfold, kissing the side of his neck.

"So basically this is going to be a guessing game," Kirstie explained. "One of us is going to do something and you have to guess who it is."

Leonard frowned. "I think I'll be able to tell you apart. I know Penny pretty well, know how she does things, know what she feels like."

Kirstie chuckled. "You'd think that, but trust me, you won't."

Moments later he felt kisses being placed on his abdomen. The sensation, combined with not really knowing who was kissing him, caused an immediate physical reaction. The kissing ended after maybe a minute.

"So, who do you think did that," Kirstie asked.

"Uhm, you?"

"Nope," Penny replied.

"Okay, so I won't know. So, how is this a game?"

"Because," Kirstie said, drawing out the last syllable. "The number of times you guess right, out of ten rounds, will equal the number of fantasy's you get to experience during the remainder of the day."

Leonard frowned slightly, knowing instantly why Kirstie had decided on that particular price. The frown only lasted for a second or so, before he started to smile. "That sounds like a great price."

"I'd figured you'd say that," Kirstie said, and Leonard could imagine she was grinning at him. "So, let's start with round one."

Before he had time to agree, someone's hand began to slowly stroke his erection. Leonard understood why it was done slow; the object wasn't for him to climax, but to guess at who was doing that. He tried focusing on how the hand felt, trying to determine who it was, but he really had no idea. He briefly worried about getting them all wrong, but then realized the low probability of ten wrong guesses with two choices each. "I'm gonna go with Kirstie," he said as soon as the hand was removed.

"And he scores," Kirstie exclaimed.

Leonard grinned, glad he had at least guessed correct once. "I definitely like this game," he said, immediately following it up with a groan when he felt one of the girls slide onto him backwards, leaning back toward him and placing her hands on either side of his torso. Again, he couldn't distinguish who it was, but he did know it felt amazing. The round ended too soon to his liking. "Uhm... Penny?"

"Sorry, Baby. That wasn't me."

Leonard didn't have time to respond as he felt a tongue swirling around the head of his rock hard cock. Again, he couldn't determine with certainty who it was, but he figured that with Kirstie being the right answer for the first two rounds, Penny was the most likely answer. As soon as he couldn't feel her tongue he answered, with much more confidence than before. "Penny."

"Yup," Penny replied.

Leonard grinned again, definitely liking this game. Not only did he guess right twice, this whole game was just incredibly hot. Someone moved to right beside him on the bed, and then his hand was placed in between the legs of whoever was there. He immediately rubbed gently back and forth a few times. Noticing the wetness, he slipped his finger inside. "Kirstie," he said, his finger still moving inside her. His finger could feel much more detail then his penis and he knew exactly how Penny felt, and this just wasn't her.

"Uh huh," Kirstie replied. "Keep going, please."

Leonard removed his finger. "Nope. You girls leave me hanging..."

"Sweetie, it's definitely not hanging."

Leonard smiled briefly. "I leave you hanging." He moved his finger to his mouth, wanting to taste her.

"You're seriously leaving me out to dry?"

Leonard smirked. "Well, you're definitely not dry right now." He waited for the girls to stop giggling. "Okay, I'm ready for the next round."

Penny snuggled further into Leonard's embrace. Kirstie's boss had called with an urgent matter, and she had had to leave for a few hours. She and Leonard had just been cuddling together on her bed for the past hour or so, simply enjoying each other's company. "So, you're enjoying your weekend," she asked, already knowing he did.

"Enjoying it? What do you think?"

She giggled. "I think you're definitely enjoying this. I guess it helps my friend is hot and very good at this stuff."

"Definitely a bonus," Leonard agreed. "So, Kirstie told me you guys, uhm, have been experimenting since you became sexually active?"

Penny nodded, a smile forming. "Uh huh. We both really enjoy our time together, even though we're both straight. I could seriously not tell how often she and I've had sex over the years."

"Yeah, she told me she liked it with you, but not so much with other women. So, uhm, did you ever, you know, try other women?"

Penny nodded. "Yeah, I have once or twice, but it just wasn't as good. So, Kirstie and I always found a way to have our special time together, even with me living here and her in New York."

"Huh, I thought the two of you hadn't been together for several years."

"No, we meet at least once a year, when we're both in Nebraska. It's not like I'm cheating on you, I'm just having a good time with my best friend."

"What if I was the one having a good time with my best friend?"

Penny giggled. "Hey, if you can get Sheldon to have some good time with you, go for it."

Leonard chuckled. "Yeah, no, I think I'll pass on that. But it's kinda hard for me, seeing you with someone else who's obviously in to you."

Penny sighed. "Leonard, I love you. You know that, right?"

"Yeah, I do. It's just that... Sometimes I get insecure when I see you with others, or know you'll be spending some time with them. Granted, up to now it had only been with other guys. But I have seen how you and Kirstie behave together, and at some level it worries me that you may leave me for her."

Penny moved slightly away, propping her head up on her right hand. "Sweetie, I can tell you right now that I will not leave you for anyone. You're part of my life now, and a very big, important part at that. You gotta stop doing that to yourself."

"I'm trying to, but it's just hard sometimes. You have no idea what it's like to see other people hitting on you."

"I do know what that's like," Penny interrupted him. "I can get as insecure as you when I notice some smart and attractive girl chats you up. Just because you seem to be oblivious to being hit on, doesn't mean it doesn't make me insanely jealous and insecure."

"Nobody's hit on me since Alex, and that's been, what, two years ago?"

Penny chuckled. "Trust me, girls have hit on you since then, as recently as the university party two weeks ago. And believe me, I completely understand them hitting on you, and it does give me some comfort that you don't even know you're being hit on. I know guys hit on me a lot, but I'd never let it go any further than that. Well, except to get a free drink out of it. And I know you wouldn't take it any further, even if you would realize you're being hit on."

Kirstie unlocked the apartment door with the key Penny had given her. Her boss rarely asked her to do something on the weekend, so Kirstie knew how important it was. Since she was the only one in LA, she had also been the only one to do the work. But that didn't mean she was happy about being interrupted from the amazing weekend she was having. Luckily, it hadn't taken her more than an hour to do the actual work, but with traveltime, it still meant she had been gone for two hours.

She locked the door behind her and undressed in the living room, dropping everything right next to the apartment door. The soft sounds coming from the bedroom told her Leonard and Penny were having some fun time, and Kirstie decided to be as quiet as possible and see what they were doing.

She was very surprised at the scene that greeted her. On the bed lay Penny, arms and legs spread wide and tied at the four corners of her bed. She was blindfolded and her body was covered in swirls of chocolate syrup, which Leonard was currently licking off of her right shoulder blade.

Kirstie met Leonard's eyes at that point, and she raised her finger to her lips, asking him to not let Penny know about her arrival. She then used her hand to indicate she wanted to take a picture. Seeing his understanding, she went back to the living room, retrieving her smartphone.

When she walked back into the bedroom, Leonard moved away from Penny.

"Get back here," Penny nearly growled.

"I don't think you're in a position to make demands," Leonard said, eliciting a smile from Penny, despite the clear frustration she was feeling at his departure. "I want to take a picture of this," he added.

Penny's smile grew. "Don't you have enough nude pictures of me yet?"

"Nope," Leonard said. "How can there ever be enough?"

Kirstie had moved to stand behind him, so that the sound of the camera would come from where Leonard was standing. She still didn't want Penny to know she was there as well. She wrapped one arm around Leonard, pressing herself tightly against his back, just because she wanted him to feel her. In her other hand she had her phone, which she held in front of both of them, before snapping a few pictures.

"Alright, you got your pictures, now come back here and get that chocolate off of me."

Leonard chuckled. "Still trying to make demands, are we? Maybe I should let you lay there for a while, teach you to be a little more patient."

"I've got plenty of patience," Penny asserted. "You always take forever before you finally enter me, and I never complain. If that's not patience, I don't know what is."

Kirstie placed her mouth next to his ear. "You work on her right side, I'll take left," she whispered in his ear, to which he gave a nod. They both walked as quietly as possible to their position, ready to attack the tied up girl. They remained in their spot for a few seconds, and Kirstie pointed to her breasts to indicate that would be their first target.

"Still there, Baby," Penny asked, clearly not having heard them move, though not sounding worried.

Kirstie gave a nod and dropped to the bed, her tongue immediately lapping up the chocolate around Penny's nipple. She knew Leonard was working on the other breast just by the movement she could sense. Penny shivered slightly.

"Ooh," she moaned. "Welcome back, Sweetie."

Kirstie lifted her head briefly. "Glad to be back." She took Penny's erect nipple in her mouth, sucking on it and then grazing her teeth across as she pulled back. She lifted up again and repositioned herself to lick at the trail of chocolate on the inside of her inner thigh. From the corner of her eye she saw Leonard had moved on to Penny's forearm, close to the inside of her elbow.

Penny's moans became louder and more desperate as Leonard and Kirstie moved from spot to spot. When Kirstie returned to the inside of the thigh a little later, she could see Penny was dripping on the bed. Kirstie moved her tongue closer, mixing the chocolate with Penny's wetness. It wasn't long before Penny orgasmed loudly.

"Leonard," Kirstie drew his attention. She showed with her hands what her next plan was, not wanting to let Penny know ahead of time.

"Got it," he replied, grinning.

They moved in position, but remained far enough away from her so that she would have no idea where the attack was going to be next. Kirstie grinned and winked at Leonard when they both noticed the shivering and repeated swallowing Penny exhibited in nervous anticipation. Leonard counted down from three, and both of them moved in to lick the side of Penny's neck.

"Oh, God," Penny moaned, clearly surprised and ecstatic at their choice. Kirstie knew very well it was one of Penny's most sensitive spots, and judging by the way Leonard's eyes had lit up and had grinned at her, clearly he knew it, too.

Leonard stood near the kitchen island, watching the wrestling match Kirstie had initiated with Penny on the living room floor. They had paused briefly as Kirstie suggested the loser would have to prepare supper, while the winner was going to be rewarded by Leonard.

Leonard was enjoying the show just as much as he was anticipating rewarding the winner. The two women took the phrase 'playing dirty' quite literally, both of them taking every opportunity to lick or rub each other's sensitive spots in an attempt to gain an advantage. Not that it seemed to work all that well for either of them, as the attacker would get just as caught up in it as the attackee.

Currently, Penny was pinning Kirstie down, her tongue working on Kirstie's wet folds, an action much appreciated by the redhead, as she didn't even attempt to wriggle free from under Penny. All of a sudden Penny stopped. "Ha, three seconds. I won!"

"Fuck, don't stop now! I'm so close!"

Penny smirked. "Sorry, but only the winner gets a reward."

Kirstie pouted, moving her hand in between her legs, but not actually touching herself yet. "Not even a consolation prize?"

Leonard stood up and walked over to Penny. "Isn't it common in sports to congratulate each other on a good game?" He didn't miss the thankful look in Kirstie's eyes.

Penny looked up at him with a smile and a nod. "You are right, Leonard."

Leonard remained where he was, looking down at Penny as she repositioned in between Kirstie's legs and first planted a kiss before resuming her earlier licking of Kirstie's swollen lips. It only took about half a minute before Kirstie climaxed, her hands tangled up in Penny's hair.

Penny released herself from Kirstie's grasp, grinning broadly. "Good game, Sweetie." She stood up to stand next to Leonard, who put his arm around her waist. It took Kirstie a little while longer before she could get up off the floor as well.

"Good game, Penny."

Penny turned fully toward Leonard. "Okay Loverboy, it's time for my reward."

Penny had barely closed the bedroom door before she was being pushed against it by Leonard, his hot breath on her neck, his hands on her abdomen. "I'm glad you won," he said in a low voice. "I know exactly how to reward you."

"You do, huh," Penny asked over her shoulder, her cheek pressed against the door. She gasped as he placed his leg between hers, inching them further apart.

"I do."

His confident reply increased her heart rate and it increased again as his hand moved from her abdomen down until his fingers reached her clit, barely touching it, but it had a profound effect on her regardless. Her breathing became erratic, and she moaned his name when his other hand cupped her breast, his thumb flicking her rock hard nipple.

The feeling of his erection against her bum cheek made her crave for more, her arousal already peaking. He rubbed her clit, making slow lazy circles and she orgasmed within seconds. Before being able to ask him if there was more to the reward, he turned her around, his mouth assaulting the nipple that hadn't received any attention yet and a finger started rubbing in between her folds.

She threw her head back in pleasure, not caring it came into contact with the bedroom door rather hard. It seemed Leonard was taking his job of rewarding her very serious and she knew her next orgasm was not gonna take too long to arrive. His mouth pulled back, pulling at her nipple before it was released.

Seconds later, his tongue flicked at her clit a few times and she heard herself growl. His mouth moved further down to lick between her folds, his thumb returning to her clit. "Oh, Baby." She wanted to say how amazing this felt, but she just couldn't talk. She placed her hands on the back of his head as she felt him move away.

Another growl escaped, this time out of frustration when both his mouth and thumb were no longer touching her. She was about to comment that his reward left something to be desired, but instead she yelped in surprise when he suddenly lifted her up. He carried her to the bed and literally dropped her on it. Before she could say a thing he entered her, inserting himself fully, then remaining still for a few seconds. He then pulled out of her slowly, only to slam back into her with force.

Penny's hands were gripping the back of his head again, moaning in pleasure as he again pulled out slowly, before slamming back into her hard. "Oh, fuck, yes!" She climaxed when he slammed back into her the third time, unable to hold it off.

"Turn around," he commanded a short while later as he pulled out. "Hands and knees," he added, unnecessarily, as Penny had understood immediately. Clearly, he was not done rewarding her, and she didn't mind in the least.

She was barely in position when his hands grabbed her hips and he entered again, slowly this time. He started at a slow pace but it felt just a wonderful as when he had slammed into her before. She was glad he held her by the hips, because her legs were getting weaker by the second. She couldn't hold herself up by her hands, her face now resting on the bed, as Leonard began to speed up.

She could feel another orgasm building, and she could sense Leonard was getting close to his climax. He was really pounding into her now, grunting with each thrust, his breathing labored. Penny had no idea how she managed to divert her attention, but she looked to the side to check if his inhaler was close by. Once she spotted it, she let herself be taken over by the immense pleasure he was providing. "Oh, Leonard! Oh, God! Yes!"

Kirstie glanced away from the television to the side when she heard the soft snore. Penny had fallen asleep, leaning against her. She then glanced to the other side, to see Leonard grinning at her, with a small nod toward Penny.

"Nice work, Tiger," she spoke softly. She had heard some of the things that had been going on in the bedroom while she had prepared their supper. She was very surprised at Penny's three orgasms in pretty quick succession, though Leonard had managed to get her off twice in a short amount of time yesterday. "You look pretty tired as well, Tiger," she added, noticing suddenly his eyes were almost at half mast. "Maybe I should put you guys to bed?"

"Only if you join us," Penny replied, surprising Kirstie. It was clear Penny was still tired, barely keeping her eyes open.

"But I'm not sleepy," Kirstie said.

"Leonard needs his pillow," Penny replied. "It's the last night he gets to enjoy it."

Kirstie smiled and turned toward Leonard. She moved to sit on her knees, facing him, her breasts at eye level for Leonard. "Is that true, Tiger? You need my girls tonight to sleep better?"

He just nodded, clearly too tired to talk, though his eyes were trying to focus on her breasts.

Going to bed early could have it's benefits, Kirstie realized. They might be up a little early tomorrow morning and have some fun before Penny would have to get ready. She leaned forward to reach for the remote that was beside Leonard, rubbing her breasts against his face, using her free arm to pull his head even closer. She turned off the TV, without moving away, allowing Leonard to rest his head there for a few more seconds. "Alright, let's get to bed then."

A/N2: Even Kirstie is asking for a Monday morning ;) Regardless of there being a Monday chapter or not, there will be more of her in some future stories, I promise.
