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."
