Introduction:

The Primdale siblings fool around.
Chapter 73
A Christmas To Remember

The whole family spent the next day at home. In the morning, Brit said she wanted to sketch Lissa, so they headed out back to the studio. Jeff, Allison, and even Greg accompanied them. That was really too bad, Jeff thought. With just the kids there, and possibly Allison, Lissa might be willing to go topless, or even fully nude. She most certainly wouldn't do it with Greg there, however.

He thought back to those pictures on the boat that summer, and realized that maybe he was wrong. She had gotten naked with her father after all. Jeff wondered how that had gotten started, and whether he could somehow induce a repeat performance. He hated to admit it, but it was probably Allison who had pushed them along, but now his stepmother didn't show any indication of doing the same. She had a way of getting people to do what she wanted, a talent that Jeff lacked. It just wouldn't be the same with him as the instigator.

It would be interesting if somehow the same situation could arise, but this time with Jeff and Brit in on the secret as well. While he had no desire to see his father nude, seeing all three girls without their clothes on would more than make up for it, especially if they were willing to take some pictures of the same sort as on that boat last summer. He imagined Lissa going down on him, wrapping her lips around his cock like she had her father's.

If it ever happened, it wouldn't be today, that was certain. However, he came up with a Plan B which he hoped would work. If Greg was the only thing holding them back, Jeff would just have to get him out of the way. It would mean Jeff himself would also have to leave, but he hoped that with only the girls there, Brit might get out her camera and take some pictures, pictures that she would show him later.

"Well this is boring," he complained after sitting there patiently for fifteen minutes. "Come on, Dad. Let's go shoot some pool."

Greg laughed. "I was actually going to say the same thing, although probably a little more tactfully. Sorry, Lissa. I don't mean to imply that you're not picturesque, or that Brit's not a good artist, but it's just not as much fun for a bystander. Are you coming, Allison?"

"I think I'll stay here for a while," Allison replied. "Maybe I can convince Brit to sketch me as well."

Jeff hoped that was a subtle hint that she planned to do another nude photoshoot. That brought up another interesting possibility. Perhaps Lissa and Allison might pose together. Maybe they would continue where they left off six months ago.

The two men left the studio and headed back inside, where they immediately descended the stairs to the rec room and racked up the balls. They played several games while the girls were out back. Jeff was actually glad that he had this time to spend with his dad. He still felt guilty about all the times he wished Greg would leave the house so that Jeff could have fun with Brit, Kari, Crystal, and even Allison. Greg was his father; the two of them shouldn't be enemies.

The girls returned an hour later, and they all sat down to lunch. Afterward, Lissa got out her cards again, and this time the whole family joined in the fun. By the time supper time came around, Jeff felt much better about his relationship with his father. He decided not to worry so much about it; after all, when Greg was around they still enjoyed each other's company.

That night, Allison came upstairs with the children and firmly insisted that they go to bed this time instead of staying up. They grudgingly agreed, and the three of them climbed into their own beds and went to sleep.

***

Greg still had to work most days during the vacation, which left Allison, Lissa, Jeff, and Brit at home alone the next day. Jeff was hoping that Allison and Lissa would go shopping or something so that he could spend the day alone with Brit, but it turned out that Lissa just wanted to stay home and relax.

She said she wanted to sit in the hot tub for a while, and the others decided to join her. For some reason, all three girls wore the skimpiest bikinis they owned. Jeff was glad; all three of them looked stunning in those swimsuits. His only disappointment was that with Lissa there, they couldn't go completely nude. Allison had already shown that she wasn't afraid to take her clothes off in front of him any more, and on more than one occasion the three of them had sat naked in the hot tub.

Lissa's body was gorgeous, he had to admit. She caught him staring a couple of times, but she simply gave him a knowing grin. It seemed that she liked him looking at her like that.

Brit, of course, flirted with him the whole time, finding excuses to rub her body up against him and frequently adjusting her swimsuit in an ambiguously sexy manner. Not surprisingly, Lissa did the same thing. Until the incident in the bunk bed a couple of nights ago, he had thought that their days of fooling around were behind them, but now he was pretty sure she wanted to continue their unconventional relationship. Perhaps if Allison and Brit weren't there, she would be willing to take off her bikini. That thought excited him, especially now that he had already made up his mind that incest no longer bothered him. He found himself in a similar ironic situation to a couple of nights ago. Both Brit and Lissa were willing to get naughty with him, but not with the other one watching. He wondered if he could somehow break down that final barrier.

He got his chance that night. Lissa continued to flirt with him the rest of the day, not obviously of course, at least to anyone but him. When they went to bed that night, Allison didn't accompany them, so by unspoken agreement they gathered in Brit's room. She didn't pull out the cards this time, but instead the three of them just sat there talking.

At a lull in the conversation, Jeff noticed his big sister smirking.

"What?" he asked.

"I was just thinking, do you guys want to know what I learned at college?" she asked with a wink.

"Not really," replied Brit.

"Oh, I'm not talking about school stuff. I'm talking about a more practical application."

"Like what?" asked Jeff.

"You have to promise not to tell anyone."

"I promise," said Jeff. Brit just nodded.

"Okay," Lissa continued. "I'm talking about naughty things."

"How naughty?" Brit grinned.

"I'm not sure you're old enough--"

"Shut up! I'm old enough for anything!"

"Okay. Let's see, where should we start? I know. My roommates have an agreement with the landlord so we never have to pay rent."

"What kind of agreement?" asked Brit.

"Each month, one of the girls goes over and sucks his dick," Lissa explained, trying to make it sound casual but with a scarcely concealed grin.

If she expected a shocked or horrified reaction, she was disappointed. Both Jeff and Brit broke down laughing.

"What?" Lissa demanded.

"Show me," Brit told her.

Now it was Lissa's turn to be shocked. She had thought she would have to work on convincing them, but it seemed they were just as eager as she was!

"All right, Jeff, come here," she said.

Jeff approached her, his cock already growing hard in anticipation. He would have thought she was just joking about it if the two of them hadn't fooled around before. But especially now, with a more wild and unrestrained Lissa, he was sure she was serious.

She knelt down in front of him, and her hands went to his belt buckle. She fumbled with it for a second, then opened it and unzipped his pants. She pulled them down to his ankles.

"Take a good look, Brit," Lissa said with a wink, then pulled down his shorts, allowing his cock to spring free.

Brit, still playing innocent, gasped. Her face lit up with a smile. "It's so big!" she exclaimed. "I think it's even bigger than it was this summer when we went camping with Kari and Crystal."

"Jeff must be going through a growth spurt," Lissa replied. "So tell the truth, Brit, does seeing it make you horny?"

Brit nodded with a deceptively shy look on her face.

"Me too," Lissa told her. "Have you ever fantasized about putting it in your mouth?"

"In my mouth?" gasped Brit.

"You can't tell me you haven't played with yourself while thinking about Jeff and his great big cock. I'll bet you've wanted him to shove it deep in your pussy. Or you've wanted to stick it in your mouth and suck on it. You've wondered if it would taste as yummy as it looks. Am I right?"

"Um..." said Brit. "Well... yes," she answered.

"Brit, what are you saying?" Jeff demanded, playing along. This was getting fun.

"Just that... I sometimes fantasize about you, Jeff," said Brit. "About your cock, just like Lissa said. My big brother's big cock."

"And I'll bet you've fantasized about her too, haven't you, Jeff?" asked Lissa.

"I don't..."

"Tell the truth, Jeff," said Brit. "I did."

He sighed. "Okay, yes. I've fantasized about you, Brit."

"Really?" she asked with a grin.

"Really," he replied. "I've fantasized about you wrapping your lips around my cock and sucking me off until I blow my load down your throat."

"So let's do it!" Lissa offered enthusiastically. "I'll go first and show you how it's done, Brit. Then you can fulfill your brother's fantasy."

Jeff gazed down at his little sister. "I..." he stammered. "I really want... I mean, if it's okay with you."

"I want to," Brit smiled. "Show me how it's done, Lissa."

Lissa knelt in front of Jeff with a grin on her face. She winked at him, then opened her mouth. He groaned as she let it slip inside. Lissa sucked on it, clearly displaying the dimples in her cheeks to Brit's wide eyes. Jeff knew it was just an act on his little sister's part, but he still felt a kind of thrill at doing this in front of her. It was especially nice because it was Lissa. He had to admit that he had his fantasies about her, and now it seemed that she was eager to fulfill them.

She bobbed slowly up and down on it as she smiled up at him. It felt so good, he could hardly stand it. He wanted to cum right then, but didn't want to lose it until he had it in Brit's mouth.

Fortunately, Lissa sensed his need and drew back, letting his cock slip from her mouth.

"And that's all there is to it," Lissa told Brit.

"But... doesn't it taste... gross?" asked Brit.

"I love the flavor. Trust me, if you let him shoot his cum into your mouth, you'll be instantly addicted."

"Really?"

"Absolutely. Go ahead and try it."

"Okay," Brit smiled. Lissa moved out of the way and let her little sister take her place. Brit stared at his cock for a second, then lifted her eyes to his. Out of sight of her big sister, she gave him a wink. Then she opened her mouth and took it in.

"Oh god!" he groaned as she sucked. Even skipping a single day from her nightly routine made a difference; he really missed the feeling. She bobbed up and down the same way that Lissa did, but made use of her tongue as well. She had had a lot of practice this past month and a half, and she knew exactly how to make him feel good. She had the art of sucking Jeff's dick down to a science. If she wanted him to go on for a long time, she could make it happen. Then when she wanted him to cum, she merely altered her technique slightly and within a few seconds could bring him to orgasm.

Lissa moved around to the side to get a better view. She looked excited to see her siblings engaged in this erotic act. Jeff wondered what had come over her. What had happened during her four months at school that had changed her so much? He didn't mind the change; in fact, he welcomed it. He knew he was going to remember this vacation forever.

She leaned in and licked around the base of his cock where Brit couldn't reach. The sight of both of his sisters giving him oral sex at the same time was too much. "I'm going to cum!" he warned Brit, an instant before his cock jerked, shooting the first of his load into her mouth.

"Mmm!" Brit exclaimed in almost a squeal as she drank it down. She wore a delighted smile on her face as he continued to pump out his cum, and she swallowed it with cheerful eagerness. Lissa drew back to watch the expression on her little sister's face.

Finally Jeff groaned one last time, then fell back. His cock slipped free from Brit's mouth, and he lay down on the floor, exhausted.

"You're right, Lissa," Brit grinned. "That was so tasty! I want to do it over and over and over again. You'll let me, won't you, big brother? You'll fuck my mouth and let me suck all your cum out every day? Three or four or five or ten times a day? You'll let me have it for breakfast, lunch, dinner, and snacks in between?"

His only response was a fatigued yet satisfied moan.

"Wow, you two!" Lissa exclaimed. "I can't believe how good you are at that. If I didn't know any better, I'd say you've done this before."

Jeff and Brit glanced at each other, then began to laugh.

"Should we tell her?" asked Brit.

"Why not? Just about everyone else knows. I wouldn't mind having Lissa in on the secret too."

Brit turned to her big sister. "Jeff and I have been fucking like jackrabbits for about a month and a half now," she said.

Lissa actually gasped at that. "You're not serious!" she exclaimed.

"Really," Brit insisted. "I fell in love with him shortly after you left, so Kari and Crystal and I came up with a plan to have me seduce him. It took him a while, but eventually Jeff came around."

"Oh my god, that makes me horny!" Lissa said. "My own brother is boinking his little sister."

"Boinking?" asked Brit. "I like that. Jeff's my big boinker."

All three of them laughed.

"So Kari knows about it then?" asked Lissa.

"Kari and Crystal are a part of it," said Jeff.

"What do you mean?"

"We all boink each other," giggled Brit.

"So Brit, does that mean you... well... with Kari and Crystal..."

Brit grinned. "It sure does," she replied. "Crystal is my... I believe the term we use is 'teddy bear.' Because we like to cuddle with each other when we sleep together. And of course Kari likes to join in too. And so does Jeff. So we're all just a bunch of boinkers."

"So does anyone not know what's going on between you two?"

"Let's see..." said Jeff. "I'm pretty sure that Dad doesn't. But Allison does; she was even there with Brit and me our first time. Oh, and I'm sure Rachael knows by now. Allison would have told her. In fact, now that I think back on it, I think Rachael was trying to get Brit and me together while she was here in September."

"I'll bet Allison and Rachael schemed it together," said Brit.

"Probably."

"God, you two!" said Lissa. "Or should I say, you four. Or six. I thought I was naughty, but then I come home and find out my little brother and sister are even worse. I'm going to have to try extra hard to catch up."

"Good luck on that, because we're going to be working hard too."

"In that case, Jeff, are you up for seconds?" asked Lissa. "After Brit's praise of your cum, I want my share."

He nodded. Before she went to work though, she began stripping off her clothes.

"You don't mind, do you Brit?" she asked.

"As long as I can do the same," Brit replied, unbuttoning her shirt. A minute later, both girls were completely nude. Jeff grinned at them, his cock rapidly growing hard again. He didn't even try to get back up, but continued to lie on the floor. Lissa leaned down and took him into her mouth again.

This time her technique was more like Brit's as she sucked him off. She took it slowly, but used her tongue to tease him inside her mouth. She ran the tip across that sensitive spot on the underside that really got him going, and he felt the electric thrill that he knew so well from when his little sister did it. His body responded by squirming on the floor, his hips rocking upward to spear into her mouth. She smiled at the reactions she was causing in him.

Brit scooted forward, then rose up on her legs and straddled him, right above his head. She lowered her body slowly, and he knew what she wanted. He stuck his tongue out and brushed it against her pussy.

"Ooh!" she squealed at the first contact. He continue to lick her there, even reaching up with his hands and spreading her so that he could thrust it inside. He let it run all over her clit, causing her to gasp in pleasure.

Lissa, meanwhile, tried a new technique. She opened her mouth and placed her teeth gently just behind the head. Then she flicked her tongue repeatedly against the tip.

"Oh my god!" he exclaimed. "That's too much! I'm going to... I..."

He erupted into his second orgasm of the night. Just in time, Lissa closed her mouth over it to prevent his cum from escaping. She sucked it down just as Brit had earlier in the evening. He groaned as he released into her mouth.

Suddenly, they heard a knock at the door.

"Oh shit!" Brit exclaimed, climbing off of her big brother.

"Listen, you three," Allison said quietly from the other side of the door. "If you're going to have a three-way sibling orgy in this house, you'd better keep the noise down. Greg just thinks you're playing cards again, but if you get any louder, he's going to suspect something."

They heard her footsteps as she made her way back down the hall. The three of them stared at each other, then burst out into quiet laughter.

"I think maybe we'd better get to bed," Jeff suggested.

"I think you're right," Brit agreed.

***

They had a discussion about it the next morning with Allison after Greg left. She explained that she had gone upstairs to tell them to quiet down, then recognized the sounds they were making and figured out what was going on. She was certainly not opposed to them having that kind of fun; in fact, she was all for it. Unfortunately, Greg would no doubt feel differently, so she warned them to keep it quiet.

That afternoon the four of them took off their clothes and relaxed in the hot tub again. This time, there was no longer any reason to keep anything secret, so they didn't even try. Brit sat on Jeff's lap, and even let him stick his cock up inside of her. Lissa and Allison sat across from them, watching as Jeff reached around and fondled his little sister's tits.

"So Jeff," Lissa commented with a grin. "Which boobs do you like best? Those?" She pointed across at Brit's chest, "these?" She cupped her own. "Or these?" She reached over and grabbed Allison's.

Jeff gasped, his eyes growing wide. All three girls burst out laughing.

"That's not fair," Allison said, "catching Jeff off his guard like that. He's got a weakness for lesbians. If you're not careful, you're going to give him a heart attack."

"Sorry about that," Lissa replied.

"Besides," Allison continued, "you're not allowed to grab my tits unless I can grab yours." She reached over and put her hands on Lissa's.

"Oh shit!" Jeff exclaimed, his body tensing up. Brit's eyes opened wide for a second, then a grin spread over her face.

"Well, it looks like you did the trick, you two," she said. "You just gave Jeff an orgasm."

***

After the events of the past few days, Jeff was sexually exhausted, so for the rest of the day he just rested. Lissa apologized, saying it was her fault, so she had him lie on his stomach on the couch while she massaged his shoulders. It felt nice, like when they used to give each other back rubs back when Lissa was still living at home.

That evening after Greg returned home, they all played games downstairs in the rec room. They played doubles at ping-pong, with Jeff and Brit paired against Greg and Lissa. Allison watched from the sidelines. Every time the two younger children scored a point, Brit jumped on her brother's back in enthusiasm. It was so amusing that everyone had to laugh whenever she did it, and soon she started doing it just to see their reactions.

When bedtime came along, the three children headed upstairs. After the shock of being caught last night, they decided not to get together tonight, even to play cards. They still had all vacation to have fun, so missing one night wouldn't hurt too bad. They all agreed that if they didn't stay up late every night, Greg and Allison would be less likely to come upstairs and tell them to go to bed on the nights that they did. Jeff headed into his own bedroom, and the two girls changed into their pajamas and climbed into their bunks.

As Lissa lay in bed, she thought once again about the new version of herself. It was so exhilarating to have no regrets about anything she did, to be able to have fun whenever and with whomever she pleased. Not only had she had sex with three men at once, gotten involved in a lesbian threesome with her roommate and her roommate's girlfriend, but now she had even given a blowjob to her own brother. Whoever came up with the idea that incest was wrong didn't know what they were missing. In fact, she had had at least some kind of sexual contact with almost every member of this family.

Almost. She grinned as she realized that that meant she had one more conquest to make.

She sat up, then threw off the covers and climbed down the ladder to the floor below. She knelt by her little sister's bed, then reached out and cupped her cheek.

Brit opened her eyes. Lissa smiled tenderly at her. "Hi," she said.

"Um... hi," replied Brit.

"I was wondering, would you mind if I slept in your bunk with you tonight?"

"Why do you want to sleep with me?"

"Because I'm feeling kind of lonely. I just want to cuddle with someone tonight."

"Oh, all right," Brit smiled. Lissa climbed into the bed next to her and slipped an arm around her waist. Brit glanced at her, perhaps a little confused at the gesture.

"Do you remember the last time we slept together like this?" asked Lissa.

"The camping trip, a year and a half ago."

"So you do remember," Lissa grinned. "Of course, Jeff slept with us too that time. He was so sweet, looking out for you like that."

"Yes he was," Brit grinned. "Even back then I loved it when he held me in his arms. Of course, I had no idea that we would end up being lovers, but still, it felt really nice."

"What about you and Crystal? And Kari?"

"Oh, that feels really nice too. There's something really beautiful about making love to another girl. It's different from making love to a boy, even one as wonderful as Jeff."

"I know," said Lissa.

Brit glanced at her again, surprise in her eyes. "You know?"

"I'll tell you a secret," Lissa grinned. "I've been having sex with one of my roommates."

Brit actually gasped at that. Lissa giggled at her response.

"Actually it was me and her and her girlfriend," she added. "Just like you and Kari and Crystal."

"So you like girls too?" asked Brit.

"Absolutely. Take you for instance."

"Me?" asked Brit.

"Yes, you. You are so cute I can't stand it. I'm going to be honest with you, Brit. I find you very attractive."

"Oh my god!" Brit breathed. "Are you serious?"

"I'm completely serious. When I found out that you've been having sex with other girls, you wouldn't believe how much that aroused me."

"Lissa," whispered Brit. "Are you... are you hitting on me?"

"Yes," Lissa grinned. "If you're willing, I'd like nothing more than to make love to you."

"Oh god," said Brit.

"I'm sorry. Look, if it makes you feel uncomfortable, just tell me and I'll stop."

"But that's just it. I don't feel uncomfortable. You're very sweet, Lissa. And very beautiful. It's just that you've changed so much since you left. You've always been there to look after me, to keep Jeff and me from killing each other, and to cheer me up when I was sad. I've always loved you. I just don't know if this is what I want."

"Well, will you at least think about it? Tomorrow night, let me know your answer."

"Okay."

"I love you, Brit."

"I love you too, Lissa."

The two of them cuddled together for a few minutes. It felt so nice and relaxing that Lissa found herself quickly drifting off to sleep.

"Lissa," whispered Brit, and Lissa opened her eyes.

"What is it?"

"I've decided," Brit told her. "Yes."

"Yes?"

"Yes, I want you to make love to me."

"Right now?"

Brit nodded with a smile on her face. Lissa leaned in and kissed her on the lips.

"I hope you don't believe in Santa any more," she grinned, "because we're about to get naughty enough to make up for a whole year's worth of being nice."

"Maybe we'll get lucky and he's already made his list and checked it twice," replied Brit. "Of course, unless he had it finished before September, I'm definitely on his 'naughty' list this year."

"Well then, we have nothing to worry about."

Lissa rolled over off of her and sat up. There wasn't a lot of room to maneuver in the bottom bunk, but she managed to wriggle out of her tee-shirt, uncovering her chest. Brit gazed up at her breasts with a smile on her face.

"Your body is so beautiful," she commented.

"Thanks," Lissa replied. "Are you going to give me the chance to return the compliment?"

Brit nodded. She reached down to the base of her shirt, but her sister put a hand there to stop her.

"Mind if I do the honors?" asked Lissa.

"I'd love that," Brit replied.

Lissa lifted the bottom of her shift just a little, then leaned down and kissed her just above the waistband of her panties. Brit gasped at the sensation, keeping that smile on her face. Lissa smiled back, then lifted the shirt a little more and kissed her again. Slowly she worked her way up, inch by inch, kissing her little sister's body as she worked. By the time she reached the breasts, Brit's breathing had turned deep and heavy. She twitched whenever Lissa's lips touched her skin, a reflexive response to the stimulation.

Brit wore a bra, so Lissa slid the shirt over the top of the twin mounds, then ran her tongue down inside the cleavage, causing a soft yet audible whine to escape from Brit's lips. Lissa giggled quietly, then rose up and took hold of the shirt with a firm grip.

Brit lifted her arms, and in one swift motion, Lissa had the garment off. She reached down and fondled her little sister's breasts through the fabric of the bra. Brit lifted her own hands and took Lissa's tits in them, to the older girl's delight.

"That feels nice," Lissa told her. She leaned over, bringing her body down over the top of her little sister. Her breasts rested atop the younger girl's, causing them both to giggle this time.

Lissa's hands slipped under the torso of her little sister, who raised her chest to give her more room and subsequently increased the pressure between the two sets of boobs. Lissa found the bra clasp and unhooked it. She took the ends and pulled them out and up. Brit raised her arms once more to help her big sister remove it, and in a moment the two of them lay there, bare chest to bare chest. Lissa lowered her head once more and kissed Brit deeply and fully on the lips, letting her tongue penetrate into the girl's mouth. Brit kissed back, teasing her sister's tongue with her own.

Lissa found her own heart pounding in excitement and lust. Brit really was a gorgeous girl, and her body was so soft. There was something particularly delightful about the body of a young teenage girl that wasn't quite the same with girls her own age or older. It wasn't that she had any problem with Meg's or Sandy's; she just enjoyed Brit's better.

From the feel of Brit's hard nipples and the little sounds she was making, Lissa could tell that she was enjoying herself as well. The two girls remained in that passionate embrace, continuing to kiss each other hungrily and gently caressing each other for about five minutes. Then Lissa rose back up and stared down at the little beauty.

"You've turned into a gorgeous young woman," she said. "Your body is absolutely perfect for your age."

"My boobs aren't as big as yours though," Brit said.

"Well, I happen to like little boobs, especially on a little girl like you."

"I'm not so little any more."

"I've noticed that." Lissa lowered her head once more and took her sister's nipple in her mouth. Brit mewled quietly as Lissa sucked and licked at it, pleasuring the girl's body in the ways she knew felt good on her own.

She moved to the other nipple and spent a few minutes there, teasing it in the same way and causing Brit to gasp in pleasure. It was too bad that they had to be quiet, because Lissa knew from personal experience that when a girl got that excited, she wanted to just let it go and cry out.

She let her hand roam down her sister's body until it reached her panties. She found them, not surprisingly, damp. She slipped her hand inside and ran her fingertips across the slit. Brit did cry out then, but it was more a quick yelp than a prolonged moan.

"Shh!" Lissa grinned, putting a finger to Brit's lips. Brit giggled silently for a moment.

Lissa slid off the bed and knelt beside Brit's body. She grasped the waistband of the girl's panties and drew them down toward her feet. A moment later they came free, and she dropped them on the floor. Brit spread her legs as Lissa leaned in and kissed her there.

"If I'm going to do this," Lissa told her, "you're going to have to do the same for me."

"Let's do it at the same time," Brit smiled enthusiastically.

Lissa climbed back into bed, this time lying in the opposite direction of her little sister. Brit sat up and took a moment to peel off Lissa's panties, then they lay back down again. Lissa spread her legs and Brit rolled over on top of her, and each of the girls aligned their cunt with the other's face.

At the same time, they opened their mouths, stuck out their tongues, and set to work licking all over their partner's pussy. They both were experienced enough at this by now that they knew just what to do. Their lips, tongues, and fingers attacked each other mercilessly, plunging deep inside or tickling the clitoris. Brit kept her weight on her knees to keep from putting too much pressure on her sister's face, but Lissa grabbed her by the ass and pulled her down to allow for much deeper penetration with her tongue.

Both girls panted and gasped as their incestuous, sapphic lovemaking continued. Within minutes their bodies began to quake in the throes of a multitude of small orgasms. They let these orgasms run through their bodies but didn't let up on their enthusiasm; neither girl wanted to end this blissful encounter.

When exhaustion finally overtook them and Brit rolled over off of her sister, Lissa glanced over at the alarm clock, and was surprised to see that it had been over two hours since they had first climbed into bed. She smiled to herself as she wondered if tomorrow night they could try for three.

***

Greg had invited the Williams family over to spend Christmas Eve at the Primdale's, so Allen, Kari, and Crystal arrived the next morning. Lissa gave Kari a big hug; they had always gotten along well, and hadn't seen each other for four months either.

They divided into three groups. Brit and Crystal went back out to the studio, Jeff went downstairs with Kari and Lissa, and the adults stayed upstairs in the front room to talk.

Kari's presence reminded Jeff of something. While in one sense it was probably trivial, to him it was important.

"Kari," he said quietly, so that the adults upstairs wouldn't hear. "I have a confession to make."

"I knew it!" she said playfully. "You're actually an alien being sent to take over the world."

"Not exactly," he replied. "I'm not one to kiss and tell, but on the other hand, I have an obligation to you."

"You've been cheating on me behind my back?" she grinned.

"Well, that's why I'm telling you now, because I don't want it to be behind your back. A couple of nights ago, Lissa and Brit and I--"

"Say no more," Kari interrupted. "You had sex with Lissa and you're feeling guilty because you didn't get my permission first, right?"

"Basically, yes," he replied. "I mean, it wasn't..."

"I gave him a blowjob," Lissa explained.

"Well, you can stop feeling guilty," said Kari. "I'm sure you wouldn't have done it if you thought I would mind, and that's good enough for me. I figure if I can have sex with my sister, I should allow you the same privilege. Welcome to the club, Lissa."

"The club?"

"Me, Jeff, Crystal, and Brit. And now you. We're all each other's lovers. Although maybe I shouldn't assume too much."

"What do you mean?"

"Well, if you're going to join our little group, you're going to have to be willing to get together with all of us. All of us, if you get my meaning."

Lissa grinned. "And you're wondering whether I would be willing to be with another woman, is that right?"

Kari nodded.

"Does this answer your question?" Lissa leaned in and pressed her lips against Kari's. Jeff almost gasped at the erotic sight of two very beautiful girls kissing right there in front of him. They held out that kiss for almost thirty seconds, then finally Lissa drew back.

"Yes, that answers my question," Kari laughed.

"It's just too bad we won't have the opportunity to have some real fun during the vacation," said Lissa, "but if you're patient, I promise to make it up to you this summer."

"It's a deal," Kari told her. "But in the mean time, you wouldn't be opposed to a little groping, would you?"

Lissa grinned, then reached down and pulled up her shirt. It was not the most surprising thing in the world to see that she wasn't wearing a bra. "Grope away," she told Kari.

Kari reached out and grabbed her breasts. "These feel nice," she said.

"They taste nice too, or so I've been told."

Kari leaned in, then stuck out her tongue and ran it over one of Lissa's nipples. She licked all around it until it grew nice and hard. Then she took it in her mouth and sucked.

Jeff loved the sight before him even more than he loved seeing the girls kiss each other. He wished he had a camera to record this image forever. He had no doubt, though, that it would remain in his memory for a long time.

Unfortunately, there wasn't time to do anything else, because a few minutes later they heard footsteps on the stairs. Kari sat back and Lissa hurriedly covered herself, just before the three grownups entered the room.

"We thought we would shoot some pool," Greg explained. "Do you three want to join us?"

The kids glanced at each other. Jeff would have preferred to be left alone with his girlfriend and his sister, he was willing to settle for some less risqu?ntertainment.

"Sounds fun," Lissa shrugged. "Two teams of three? Kids against adults?"

"You realize that you're an adult now too, don't you?" asked Allison.

"Oh, I'm not in any particular hurry to grow up," Lissa smiled.

"I can certainly understand that."

They shot pool for the rest of the morning, then sent Jeff out back to retrieve the younger girls for lunch. He was not surprised to see them naked and making out on the couch. They dressed and followed Jeff back into the house.

After lunch, Lissa and Allison started fixing supper, which consisted of a large ham and about a trillion side dishes. Allison liked to go all out for Christmas dinner, and this year was no exception.

Jeff spent the afternoon with Kari, of course. With everyone home they didn't have much privacy, so there was no chance for sex. That didn't bother Jeff; he had plenty of opportunities to see Kari alone these days, and in the mean time, there was always Brit, and now Lissa as well.

They spent most of the time just talking in the front room with everyone else, although Jeff and Kari did steal the occasional kiss. Jeff felt a little self-conscious about kissing her in front of Greg and especially Allen, but neither father made a big deal of it. That gave him a little more confidence, so they kissed more and more frequently as time went on. Brit and Crystal teased them incessantly of course, but the adults merely gave them amused smiles.

The Williams family stayed for dinner, which was a fun time. There was something about good food (and Allison always made good food) that put people in jovial spirits, especially around the holidays. Crystal and Brit were as playful and flirtatious as always, Kari kept playing footsies under the table with him, and Lissa and Allison talked and joked like old friends. All in all, Jeff was in a great mood.

It was too bad that Kari and her family had to leave after dinner, but everyone needed to get to bed early "so that Santa could come," Allison insisted, although no one in the either family was young enough to believe in him any more. Jeff gave Kari one last goodbye kiss, then Allen and his girls climbed into their car and drove away.

That night, Lissa didn't even make a pretense of sleeping in the top bunk. The girls continued to play cards with Jeff for an hour or two after going upstairs for bed, but as soon as he left the room, the two sisters stripped off their clothes and climbed in together in the bottom. This time Brit said she just wanted to cuddle, so Lissa didn't push her. They just lay naked together, holding each other in their arms. There was an unspoken understanding between the girls that, while the sex was nice, it was more just a one-time thing to strengthen their relationship as sisters. They had done it once almost just to get it out of the way, just to remove any doubt about whether it would ever happen between them. No longer did they need to second-guess each other's motivations or feelings; no longer was there any awkwardness as they tried to guess whether their affection was just as sisters, or something more. Now they could be comfortable either having sex or not having it. Lissa still loved to hold Brit's warm body in her arms, though. After Rachael, Allison, Meg, and Sandy, she no longer had any aversion to touching a girl like that, but rather enjoyed it.

In the morning, they got up early, met Jeff in his room, then headed down the stairs for the presents. They pounded enthusiastically on Greg's and Allison's bedroom door until the two grownups emerged, groggy but smiling. They headed out to the Christmas tree, where they set to work turning the hall into a mess of wrapping paper and cardboard.

Their time this year was just over fifteen minutes. Greg joked that they must be slowing down in their old age.

When Lissa unwrapped her present from her roommate Meg, she burst out laughing. It was a sheer teddy made of material so thin as to be nearly transparent. There was absolutely nothing innocent about it at all.

"That's... interesting," commented Greg.

"It's an inside joke," Lissa explained. "Meg's got a really warped sense of humor. She said she was going to buy me something like this for Christmas, but I didn't believe her."

"If you don't want it, I'll take it," said Allison, flashing a knowing look at Greg, whose face lit up with a grin.

"Oh no," Lissa replied. "I'm going to hold onto this. It will serve as a reminder that I have to find some way to get her back."

Jeff kept his good mood for the rest of the day, and it even increased that night when they went to bed. Brit said she wanted to sleep with him, but then Lissa said she did too. In the end, they compromised by pulling the blankets off of the bed and laying them on the floor in Brit's room, since Jeff still hadn't learned to keep his clean. The three of them stripped off their clothes and lay down on the floor.

"Jeff," said Lissa. "Tonight I want you to give me a very special Christmas present."

"Is it what I hope it is?" he asked with a grin.

"I want you to make love to me."

"Yep, that's what I was hoping."

He glanced over at Brit to make sure she wouldn't be jealous, but she was watching with interest and an amused smile.

He turned his attention back to Lissa, who leaned in and kissed him on the lips. Jeff accepted the kiss, enjoying it even though she was his sister. He remembered, years ago, when she had kissed him like this to torment him as punishment for being mean to Brit. In the end he had found it a rather pleasant torture, and now it was not torturous at all.

Jeff reached out and wrapped his arms around her, crushing her to his chest. He loved the feel of her body, the softness of her boobs with her hardening nipples poking into his chest, the smooth silkiness of her skin. Once upon a time the thought of holding his sister like this would have bothered him, but he had long since moved beyond that.

When Lissa drew back, she sighed in contentment. "I love you, Jeff," she said. "You know that, don't you?"

"Of course," he replied. "And I love you too."

"And I love you both," Brit grinned.

"Oh, come here, you," Lissa said with a giggle, grabbing her and pulling her in to a group hug. The three of them took turns kissing each other for several minutes, then Brit finally backed away.

"Well get on with it," she laughed. "I want to watch you two fuck."

"I can't argue with that," Jeff shrugged. He held Lissa as he lay her gently down on the floor, then leaned in and kissed her on the neck. She sighed again from the contact, reaching up and holding onto his head. He let his lips wander lower, eager to taste her sweet breasts, especially those nipples.

As he moved down her body, Brit slipped her hand between her sister's legs. Lissa spread her knees, allowing the girl to gently rub her. Jeff watched excitedly from his vantage point at her chest, loving the sight of one sister fingering the other.

When he reached one of Lissa's nipples, he opened his mouth and let his tongue explore it. He heard Lissa gasp at the sensation, so he continued teasing her. Brit's free hand went to Lissa's other breast, squeezing and fondling it. Then the younger girl lay down next to her big sister and sucked her nipple into her mouth.

"Oh god, you two!" Lissa whispered, keeping it quiet so as not to alert their parents. No doubt they were having their own private party downstairs, but that was no reason to risk alerting them.

Jeff let his own hand wander down to join Brit's on his sister's pussy. The two of them ran their fingers over it, tenderly rubbing her and watching as the stimulation caused her body to writhe around on the floor. Lissa's eyes were closed and her breathing heavy as she smiled in the glow of the pleasure.

"Jeff..." she finally gasped. "I want..."

He knew exactly what she wanted. Brit pulled back and withdrew her hand, giving Jeff room to roll over on top of her. He gazed down into her beautiful face, the face of his big sister. Together they had taken their first steps into the world of sex, exploring each other and learning to make each other feel good. Although he adored his little sister, there was a special place in his heart for Lissa, the beautiful girl who had accompanied him on the beginning of that journey. Now they were about to finish it together.

He lowered his hips, feeling himself penetrating into her. She sucked in her breath, but the smile on her face told him it was from pleasure rather than pain. Jeff continued descending onto and into her, loving the feel of her tight cunt around his cock. Finally, he buried it completely inside of her, and they both let out a sigh.

"I've been wanting to feel like this for years now," Lissa told him, wrapping her arms around him and holding him tightly. "Jeff, make me feel like a real woman."

He lifted his hips and plunged into her again, and she barely stifled her moan. He repeated the motion, working himself into a slow rhythm. Her own hips raised up to meet him, falling in time with him. Their bodies became almost like extensions of one another, working in absolute harmony to give them both pleasure.

Jeff kissed her deeply and passionately as they made love. He couldn't get enough of his big sister. Despite what the world might think of this relationship, it felt so right.

How long he floated in that world of passion, that world where only Jeff and Lissa existed, he didn't know. It was a timeless world where the passion between them went on forever. He thrust over and over into her body until finally, after an eternity, he felt the rush of pleasure that signaled his impending orgasm. At the same time, he felt her own body tense up, and she bit down on her lip to contain the scream that otherwise would have alerted Greg and Allison to their activities. Her legs tightened around his hips and her pussy clamped down on his cock, which pushed him over the edge. He erupted inside of her, his cock twitching as he released again and again into her steaming hot body.

Finally the pleasure waned, and he rolled off of her. She curled up next to him, laying her head on his chest and wrapping an arm around him.

"Merry Christmas," she told him.

"Merry Christmas," he repeated.

Brit crawled around so that she could lie down on his other side. He wrapped his arms around both of his sisters, and together they drifted off to sleep.

They slept on the floor for the rest of the vacation, engaging in a little silent sex play each night. Greg never suspected anything, fortunately, and since Allison had already admitted that it didn't bother her, their secret was safe.

It was too bad that Lissa had to leave a week later to fly back to school. Just when Jeff was just getting used to thinking of her in a sexual way again, she had to depart.

The night before her flight, she gave him a nice, long blowjob to remember her by, and cuddled with him all night. It seemed that she didn't want to leave either, but there was nothing that either of them could do about it. She promised to come back for summer, though, and then they would have several months together. That made him feel much better, and so as they said goodbye to each other at the airport, he was able to keep his composure.

Brit cried of course, but that was just her way. She was always very emotional. Jeff put an arm around his little sister to comfort her, and that seemed to help.

Lissa waved to them just before she disappeared down the hall, and then the four remaining Primdales returned to the van and drove back to a house full of good memories.

Greg thinks a photoshoot with his daughters is boring, after having had Lissa go down on him, back on the boat? I know six months has passed, but wouldn't that experience have been memorable enough to keep him in the studio?

Then again, if we take it as given that the only ulterior motives at play are to set up new combinations for hanky-panky, hauling Greg and Jeff out of the scene works as well as anything.

The sibs get together for oral fun, of course. Then the Allen kids join in. Of course. Somewhere in there, we learn that Jeff Primdale is not entirely averse to having his tongue engulfed by the genitalia of his baby sister. So that's something (though he doesn't get her off). And then, of course, Lissa and Jeff get together for full-bore copulation. Of course. Plenty of sweetness. Of course.

Then Lissa gets back on the plane, off to new adventures, with twenty-six chapters to go. Hmm. There might be time for Daddy to expand his horizons, after all.

A.P.
