Rachael was still lying in her arms when Lissa woke up in the morning. Lissa just stared at her for a few minutes, trying to sort out her own thoughts and feelings. It was something she had never experienced before; Lissa had always been a good girl, never one to do something so dirty. But she couldn't deny that she had enjoyed it.
For now she decided to just call it an experiment and leave it at that. So now she had had a lesbian encounter. That didn't mean she was a lesbian; it was just one time after all. She still liked men, not women.
Rachael woke a few minutes later. She kissed Lissa once on the chest, then sat up and stretched, smiling brightly.
"I told you you would like it," said Rachael, then reached out and put her hand on one of Lissa's breasts. "Are you up for seconds?"
"No," Lissa told her. "Look, I..."
Rachael removed her hand. "So you haven't really converted over then," she nodded. "Oh well. It was worth a try."
"I'm sorry," said Lissa.
"Don't be. You let me do it once, and that's good enough for me. If you ever feel like getting naughty with another girl again, though, keep me in mind."
"I won't. This was just to see what it would feel like. I'm not going to do it ever again."
"We'll see," Rachael said with a wink. Then she picked up her tee-shirt and panties and headed for the door.
"What are you doing?" Lissa demanded.
"I've got to get downstairs before the others wake up," she explained. "What would they think if they saw that I had slept in your room?"
"But you're naked!"
"I'll dress downstairs."
"But what if they see you?"
Rachael laughed. "I like to take risks," she explained, then opened the door and slipped outside.
Jeff was sitting at the dining room table eating breakfast when Rachael appeared in the hall, completely naked. He stared in shock as she glanced around, then spied him. Her face lit up with a grin, and she motioned for him to come over. He did so, and she took his hand and pulled him into the front room.
"Why are you... I mean...?" Jeff stammered.
"Because I slept in the nude last night," she explained.
"But you weren't on the couch when I came downstairs," he said.
"That's because I didn't sleep on the couch."
"Where did you sleep then?"
Rachael grinned. She slipped her hand down inside his sweat pants and wrapped them around his cock, which was rapidly hardening. Then she leaned in and whispered, "With your big sister."
Jeff gasped, and his cock spasmed, causing Rachael to giggle. She withdrew her hand, to his disappointment.
"I wanted to see your reaction," she explained. "Or more accurately, feel it. You like that, don't you?"
He didn't know the answer to that question. She already knew he liked the idea of girls with girls, but his sister...
"You have to promise not to tell her," Rachael insisted. "Or anyone else, for that matter."
"But did you two...?"
"Yes we did. At least, I did to her, but since this was her first time I didn't expect her to reciprocate. That's why I need you to take care of me."
"Take care of you?"
"I've got to have an orgasm, or I'm going to explode," she said. "I could just play with myself, but I'd rather have someone else do it for me." She immediately grabbed his hand and placed it on her crotch. "It's not as good as lips, but until you warm up to the idea you'd probably think that's disgusting. And it's not as good as a cock, but that could be messy. So I'll have to settle for your hand," she said.
"But... right here?"
"Yes, right here in the front room, where everyone can see us if they come downstairs. And if you do a good job, I'll take care of your needs as well."
A little frightened of being caught, he began to rub her. She spread her arms over the back of the couch and gripped it in anticipation of the coming pleasure. At first she sat there immobile, but as the pleasure built she rocked her hips forward with each motion. He could feel moistness on his fingers, and her lips were beginning to spread. He let his fingers find her opening, slipping them in on the downstroke and back out on the upstroke. Her grip on the couch tightened and she threw her head back with her eyes shut tightly. Her mouth was closed, but he could hear little mewling sounds in her throat as she fought to keep from crying out.
He couldn't help himself, but leaned down and kissed her on the nipple. She gasped in pleasure and shock at the unexpected sensation. Taking that as a sign to continue, he licked all over it, and even held it in his teeth and nibbled gently.
As his fingers explored her opening, he could feel her starting to tense up around them, and he knew that she was close. He sucked her nipple into his mouth as hard as he could to maximize her pleasure.
Her orgasm was intense, but thankfully silent. She thrust her hips forward against his hand as if trying to drive his fingers deeper inside her, shuddered violently as she clenched her eyes shut tightly and grimaced in the height of pleasure, then finally collapsed back on the couch. Her hips continued to rock back and forth for about a minute longer as the pleasure died down, then finally she sighed and relaxed. Instinctively, he leaned over and kissed her on the lips. She kissed him back, putting a hand behind his head to hold him there. When she released him and he drew away, he could see the smile of contentment on her face.
"You kiss like your sister," she commented. "Have you two been practicing together?"
"Uh... no..." he stammered, growing red.
"That's right, you said you'd never kissed anyone before me. So maybe being a good kisser is hereditary. I suppose there's one way to find out. I'll just have to kiss your dad."
"Later, though. Maybe after he comes home tonight."
"Oh, very funny."
"It wasn't a joke. But I forgot, I promised to take care of you, Jeff."
"Um, maybe we should do it in my room," he told her. "I don't want to make a mess on the couch."
"Good point. I guess I'll just have to swallow."
He grinned in anticipation as she slid down onto the floor in front of him.
She didn't disappoint him. She kissed the tip of his cock, and let the kiss open up into a slurp as the head disappeared into her mouth. She didn't stop there, though, but lowered her head along it until it reached the back of her throat. Then she pulled her head back until just the tip was in again.
She repeated this motion over and over again, sucking hungrily as she did so. Jeff watched her cheeks deflate each time she pulled back and let himself enjoy the stimulation.
It was her tongue that really drove him wild. She licked all over his cock, teasing it especially hard when just the tip was in her mouth. It danced over the head, sometimes pressing against the slit as if trying to burrow its way inside. It was almost a ticklish sensation, but in a good way. He loved the intensely erotic feeling.
She sped up her motion and at the same time sucked even harder. He didn't think it was possible, but the pleasure felt even more intense. He threw his head back, shut his eyes tightly and gritted his teeth, trying not to let out the moans of pleasure that threatened to escape his lips at any moment. Just like Rachael a few minutes ago, he began to rock his hips back and forth in unconscious motions.
She sensed his movements and wrapped one of her hands around the base of his cock to keep him from spearing it into her too far. She brought the other one up and began to tease his balls, running her fingernails lightly over them. That served to heighten the stimulation, pushing him closer and closer to a climax.
He could feel the pleasure mounting, and he smiled as he realized that Rachael was about to give him his third orgasm. His heart pounded in his chest and his breaths came in gasps. He was almost there...
A sudden movement off to the side caught his attention, and he turned his head. To his astonishment, Lissa stood there in the great hall, a look of shock on her face as she stared into the living room. Her eyes seemed to be fixed on the point where his cock disappeared into Rachael's hungry mouth.
The thought that he was putting on a show for his big sister was enough to push him over the edge. He gritted his teeth to keep the sound from escaping as he let the thrill overtake him, and he released his load. Rachael gulped it down eagerly and kept sucking as he shot over and over again into her mouth. Lissa continued to watch in fascination, her look of shock giving way to one of delight.
It finally ended, and Rachael let his cock slip from her mouth. She placed it back inside his pants as Lissa ducked out of view.
Rachael stood up. "We'll have to do this again some time," she said as she started searching through her bag for some clothes to wear.
"Definitely!" he exclaimed with a grin.
"So tell me Jeff, who's your favorite babysitter now?"
"Is there any doubt?" he laughed.
"Well, I guess I'd better go take a shower," she said, then grabbed her duffel bag and headed down the hall to Greg's and Allison's room, leaving Jeff on the couch feeling absolutely wonderful.
After resting for a few minutes with a broad smile on his face, he got up and headed back into the kitchen to continue his breakfast. He had just about finished when his little sister appeared in the hall.
"Hi, Brit!" he grinned.
"You sound particularly cheerful this morning," she replied. "What happened?"
"Nothing. I'm just happy to see you."
"That's a first," she giggled.
"I just don't feel like being in a bad mood today," he smiled. "So let's not spoil it, okay?"
"Aw, you're no fun," she teased, but he just laughed. She sat down at the table and poured herself a bowl of cereal.
A few minutes later Rachael returned from the bathroom, dressed in a tee-shirt and shorts. "So how's cute little Britney doing this morning?" she asked with a wide grin.
"Well, why not?" asked Rachael. "Apparently you're the popular one this morning, Brit."
"That or there's some kind of conspiracy going on here."
"You found us out," Jeff said. "We've got an evil plot to trick you into getting in a good mood, and then... well, we haven't really planned any further than that yet. But trust me, our plot will be suitably diabolical!"
"Well, the first part's working," she smiled.
Rachael stood back up. "I need to go see your sister for a minute," she said.
"Aren't you going to eat breakfast?" asked Brit.
"I already ate," Rachael replied, and Jeff snorted as he tried to keep from laughing.
"What's that all about?" Brit demanded.
"Just an inside joke," said Rachael, then headed for the stairs.
Lissa was sitting on her bed when Rachael knocked on the door and entered. Rachael came over and sat down beside her.
"I figured I should come talk to you before Allison and your dad get back," she said. "Lissa, if you feel at all bad about what happened, I want you to know that you did absolutely nothing wrong."
"Nothing wrong?" Lissa said. "But I let you..."
"Don't you dare blame yourself," Rachael insisted. "It was my fault, not yours. I won't say I wish it didn't happen, because I'm glad it did. You're an absolutely gorgeous young woman, and I've been attracted to you since I first met you."
"Please don't," said Lissa.
"So it does bother you. I'm sorry. I don't want you to hate me, but better that than to hate yourself. If you want to put all the blame on me, I'm perfectly willing to accept it."
"It's all right," Lissa sighed. "I knew what I was doing."
"Let me give you a word of advice then. Don't look back on the experience with disgust or horror. Remember how good it felt and think of it with fondness. Let it be a wonderful memory, even if you never do anything like it again. Then you won't feel so bad about it."
Lissa nodded. "Okay. I can do that much at least. I hope it doesn't sound like I'm mad at you, Rachael. I really do like you. I just can't do this again."
"I understand, and I'm glad that you like me. Can I still be your friend?"
Lissa laughed. "Of course, Rachael. Just don't expect me to let you take it any further than that."
Rachael leaned in and hugged her. "Thanks," she whispered.
When Greg and Allison arrived home that afternoon, Rachael ran up and gave Allison a hug. All three children were sitting in the living room playing card games.
"How did everything go?" asked Greg.
"Couldn't be better," Rachael reported. "Your kids are great. I'm jealous that Allison gets to spend so much time with them."
"So Brit and Jeff weren't any trouble?"
"They did get into a couple of arguments, but nothing serious."
"So how late did Jeff stay up?"
"Until midnight on Friday. After I sent Brit to bed, we went downstairs and watched a movie. Then on Saturday, he went to bed early. Probably tired after staying up so late Friday, the poor dear."
"Well, I'm glad you got along so well," said Allison. "And what about you three?" she asked the kids. "Should we invite Rachael back to babysit you again?"
"Sure!" said Jeff, a little too enthusiastically.
Allison laughed. "Looks like you have a fan," she told her sister.
"It feels good to be liked so well," Rachael beamed, "especially by someone like my little nephew Jeff."
"Hey, I'm not so little!" he complained, though jokingly. He understood what Rachael was doing; she was deliberately emphasizing the difference in their ages in order to minimize any suspicion about what had happened between them.
Rachael shrugged. "Okay, I'll admit that you're growing up, and that you're not just a kid anymore. Satisfied?"
"Fine," he said.
The three adults adjourned to the dining room to talk while the kids finished their game.
Rachael stayed for supper, where they all talked about their weekend. They conveniently left out certain parts, of course. To Jeff's immense relief, Rachael didn't even hint anything about it. He knew she enjoyed living on the edge, and could very easily have accidentally given it away.
After dinner, Jeff retired to his room, where he spent most of the rest of the evening lying on his bed, staring up at the ceiling and reliving the events of Friday night and Saturday morning over and over again in his mind. He couldn't believe how lucky he was to have a girl as beautiful as Rachael take his virginity. It was the most wonderful feeling in the world. He decided that he liked sex.
When bedtime came around, he stripped down to his boxer shorts and climbed back into bed. Just then he heard a knock at his door. Lissa opened it and stepped inside, closing and locking it behind her.
So here it was. He was about to have that talk with her that he had been anticipating all day. He didn't know whether he looked forward to it or dreaded it.
"Jeff," she said, sitting down on his bed next to him.
"I know," he replied. "We have to talk about today. You saw me and Rachael this morning."
"I'm sorry. I didn't mean to walk in on you like that."
"Don't be sorry; you didn't do anything wrong. I mean, we were right in the middle of the front room after all."
"But I... I stayed and watched. I should have just left right away. It was a private moment between you and Rachael, and I peeked."
"If I had really thought it would bother me, I wouldn't have let her do it out where anyone could see us. Just from what I know about Rachael, I'm sure she would have been delighted to know that you were watching. And it's not like you haven't seen my... well..."
She grew red. "I suppose you're right," she mumbled. "So it really doesn't bother you?"
"Not at all."
"So I suppose Rachael told you where she spent the night," Lissa sighed.
"Jeff," she said, and he was startled to see a look of fear in her eyes. "Look, I... Oh, Jeff, I know I shouldn't have done it, but I just..."
Then she suddenly broke down into tears. "I feel so dirty!" she said. "I'm horrified of what you must think of me! Promise me you won't tell Dad. I couldn't stand that."
He put an arm around her, and she collapsed into his arms, her tear-stained face against his chest. He didn't know what to do; this was the first time he had seen her cry in years. She was his big sister, always so strong, so sure of herself. He wrapped his arms around her and just sat there, not saying anything but just letting her sob into his chest.
"Jeff, if you can believe me, I'm not a bad person," she said. "This was the first time I've ever done anything like that. I just wanted to know what it felt like."
"Lissa," he soothed, "I don't think you're bad at all. You're my sister, and I'll never stop loving you." The words seemed to come naturally, and from the way they seemed to calm her, apparently they were just what she needed. "I want you to do whatever makes you happy. Personally, it doesn't bother me a bit; if you decide you like girls in that way, then I'm happy for you and I'll support you in that decision. But if you think this was a mistake, that's fine too, but don't dwell on it. Put it behind you. Personally, it doesn't bother me a bit if that's what you're worried about."
"Really?" she asked.
"Absolutely. You were just experimenting, that's all. You know I don't see anything wrong with experimenting, right? I mean, what else would you call that little incident while we were camping?" he smiled. Lissa looked up at him and laughed.
"Good point," she said. "Thanks, Jeff. But do you promise not to tell Dad?"
"I already promised Rachael I wouldn't tell anyone. Even you, but it looks like that's a moot point now. Your secret's safe with me. As long as you promise not to tell anyone about what you saw this morning."
"I promise. Jeff, I love you so much."
"I love you too, Lissa."
When bedtime came around, Allison made up a bed for Rachael on the couch. Greg noticed Allison give her sister a wink, but didn't know what she meant by that. It didn't bother him; if she wanted to share a secret with her sister, that was all right with him.
While the women talked in the front room, Greg headed into the bedroom to get ready for bed. Allison joined him five minutes later with a grin on her face. "Are you up for some kinky sex?" she said.
"What did you have in mind?"
Allison went to her dresser and opened the top drawer. She pulled out several pairs of handcuffs.
"Remember these?" she asked.
"Do I ever!" he grinned.
"We haven't used them since our wedding night. I've been saving them for another special occasion."
"And tonight's a special occasion?" asked Greg.
"It could be," she smiled. "So what do you think?"
Greg was all for the idea. Allison knew how to make sex fun; although they had been married for less than six months, he had a suspicion that it would never get dull with her.
"So who gets chained to the bed this time?" he asked.
"You do," she told him.
Greg chuckled. He was really going to enjoy this.
He began to strip off his clothes as Allison took each pair of handcuffs and attached one side of them to the bedposts. Then she began to take off her clothes as well.
As soon as he was completely naked, he lay down on the bed, face up. Allison took one of this arms, spread it out toward the nearest bedpost, then locked it in place. She repeated the gesture with the other arm, then slid her hands down his body toward his legs, making sure to brush against his hardened cock in the process. She pulled his leg to the side and locked it up with the third set of handcuffs. Finally, she went to the other side of the bed and locked his other leg in place.
Greg now lay spread-eagle on the bed, completely at Allison's mercy. She grinned and licked her lips. "We're going to have lots of fun with you tonight," she said. "I've got a special surprise for you, but I'm not sure if you'll like it or not. That's why I chained you up, because now you can't refuse."
"You naughty girl," he smiled. "What's the surprise?"
"You're just going to have to wait and find out." She sat down on the bed next to him, then reached out and grabbed his cock. He groaned as she let her hand slide up and down the shaft.
"I know what you like," she smiled. "You claim to be conservative in your fantasies, but you can't deny you have one or two tendencies that are a little wild. Nothing abnormal, of course. Just a healthy interest in a certain kind of sex."
"What are you talking about?" he asked, although he enjoyed her teasing. All the secrecy and mystery were really starting to turn him on.
"For one thing, I know you get excited by girls doing it together," she remarked.
He shrugged. "Okay, I'll admit I like lesbians. So what? A lot of men do."
"Exactly. You know I've been with other women before, right?"
Greg's cock jumped as he imagined Allison naked with another girl. She giggled at his reaction. "Apparently you like that, don't you?"
"Well... I suppose..." he said. It was really an awkward question after all. How was he supposed to answer it?
"Oh, don't worry. There's no chance of me running off with another woman and leaving you all alone. There is a chance, however, of me bringing home another woman so you can watch us."
"Oh god, Allison!" he exclaimed, that thought driving him wild.
"You wouldn't be opposed to that idea, would you?" she asked.
"No," he gasped, wondering if she was serious or just teasing. Would she really do it with another woman for him to watch?
"And of course, if you wanted to, we would let you join in. I'd like nothing more than to get fucked by my husband and a woman at the same time."
Greg couldn't believe what he was hearing. More than that, he couldn't believe the effect it was having on him. He found himself wanting more and more to take her up on the offer.
"Can you imagine it, Greg? The three of us there, our bodies rubbing up against each other, our hands exploring, our mouths kissing and licking and sucking. Can't you just see me with my lips wrapped around her nipples while you drive your cock deep into her pussy? Or maybe I would eat her out while you shove your dick down her throat. Wouldn't that be exciting?"
"Oh god yes!" he exclaimed, the thought nearly overwhelming him.
"Of course, it would have to be the right woman," Allison commented. "Someone who would be willing to do that with us. Someone not afraid to touch both of our bodies, someone who is already attracted to you and has already made love to me. I wonder if we know anyone like that?"
Greg tried to think. He didn't know too many of Allison's friends, and in fact, he couldn't remember her mentioning any of them as her former lovers.
"Wouldn't it be nice if we could find someone like that right now?" asked Allison. "As a matter of fact, I've got someone in mind."
"Really?" he said, shocked.
"Not only is she someone we both know," Allison grinned, "she's someone very close. In fact, she's standing right outside the door listening to us."
Greg's eyes grew wide. Did she really mean...?
"Rachael, you can come in now," Allison called. Rachael opened the door and stepped into the room.
Greg nearly lost it right there. So everything Allison had said was true! She really was going to involve another woman in their sex.
Rachael's face broke into a wide grin when she saw him tied there with Allison stroking his cock. Greg merely stared in amazement, almost not believing that this could be happening.
"Allison said you had a great body," Rachael told him. "I can see she wasn't lying."
Greg continued to stare, finding it impossible to speak. He realized he was naked in front of his wife's sister, but that thought, rather than embarrassing him, simply fueled his excitement.
"Remember I told you that my sister and I were lovers?" asked Allison, and Greg nodded. "Well, there was one thing I hadn't mentioned about our relationship," she continued. "You see, that first time we made love, I promised her I would share all of my lovers with her. And I've kept my promise faithfully. Every single man, or woman, that I've made love to, Rachael has too. Except one, and I intend to rectify that tonight."
"You're serious!" Greg exclaimed.
"Completely serious," Allison replied. "Tonight, you're going to fuck my little sister."
Greg chuckled. "And that's why you chained me up? So that if I refused, you could have her rape me?"
"Oh, I wouldn't do that," she said. "We would simply keep you tied up so you couldn't escape while we put on a little show for you, driving you insane with desire. By the time we were through, you would beg her to fuck you."
"Don't think we could do it?" asked Allison.
"I know you could do it," Greg answered. "That's why I'm laughing."
"You know, Greg's a little more enthusiastic than I had hoped," Rachael said. "I was kind of hoping we would have to convince him."
Allison reached out and slid her arm around Rachael's waist. "We could always pretend he has to be convinced," she said, then leaned in and gave her sister a juicy, open-mouthed kiss.
Greg groaned at the sight. It was one of the most erotic things he had ever seen. He had always thought incest was something horrible and disgusting, at least, until Allison had revealed her relationship with Rachael one night while they were making love. The thought of two sisters, especially ones as gorgeous as Allison and Rachael, as lovers had suddenly seemed more thrilling than revolting. When he was honest with himself, he had to admit that it had become one of his favorite fantasies.
Allison suddenly released his cock, and he made a sound of disappointment. It was almost cruel to get him excited like that and then leave him unsatisfied. On the other hand, when he saw her place it on Rachael's breast and fondle her over her shirt, he decided he wasn't as disappointed as he had thought.
Allison turned her head to glance down and smile at Greg. Rachael took the opportunity to kiss her on the side of the neck. Allison closed her eyes and sighed. Rachael took her own hand and placed it on Allison's breast, this time with no clothes in between. She massaged and kneaded it, pinching the nipple between her fingers.
"You know, this would be more fun if we were both nude," Allison commented, and Rachael nodded. She stepped back, then pulled her shirt over her head.
Greg found the sight of her body extremely enticing. Although she still wore a bra, the parts of her that showed looked magnificent. She had beautiful, soft-looking skin with a cute, flat stomach and curvaceous hips.
Allison reached down and unfastened Rachael's pants, then dropped to her knees and slid them down to the floor. Rachael daintily stepped out of them, leaving her long, silky legs bare.
"Do you like what you see?" Rachael asked Greg, and he nodded dumbly, too awestruck to say anything. She giggled, then put her hands behind her back to unclasp her bra.
"Allow me," her sister offered, stepping behind her and unfastening it. She slid her hands up over the shoulders, under the strap, then forward until she rested them on the girl's breasts. The bra tumbled to the ground.
"Oh wow!" Greg exclaimed as he stared at Rachael's bare chest. While he still liked Allison's tits better, Rachael's weren't far behind. She had small yet well-defined nipples, and her boobs jiggled very slightly as she moved. Allison caressed them gently, her hands sliding all over them.
As she did so, she leaned down and kissed Rachael tenderly on the shoulders. Rachael leaned her head back and she sighed in pleasure. Allison grinned as she caught Greg's eyes, seeing how much he was enjoying this.
One of her hands slid down Rachael's body until it rested over her panties between her legs. Allison pressed gently with her middle finger and she rubbed it along her sister's slit. Rachael gasped at the contact. "Oh yes, Allison!" she breathed. "I love it when you touch me there!"
"I know," Allison told her. "Nothing's too good for my baby sister. Just tell me what you want and I'll do it."
"I want your hand down inside my panties," Rachael replied, and Allison happily obliged. Greg watched in wonder and excitement as he saw the the outline of his wife's fingers against the fabric.
Rachael's hips were starting to rock forward, pressing up against Allison's hand as if trying to drive those fingers deep inside. There was dampness on the cloth now wherever it came in contact with Rachael's skin, revealing just how excited she was getting. Of course, Greg himself was probably just as excited, despite having no physical stimulation.
"Take them off," Rachael whispered. Allison knelt down behind her sister, put her hands to the waistband, and slipped Rachael's panties down to her feet. Greg was delighted to see her pussy as clean-shaven as his wife's. Her nub was just barely peeking out from the top of the slit.
Allison reached underneath her sister's legs with one hand and rubbed her fingers up and down on the lips, beginning to spread them. Rachael moaned, putting her hands to her own breasts to fondle them. Greg watched his wife's hand work expertly on her sister's pussy, loosening her up and driving her more and more wild.
"Let's give Greg something to really get excited about," Allison said, then placed her hands on Rachael's hips and turned her to the side. Allison shuffled around until she was directly in front of the girl. Greg watched in exquisite delight as Allison leaned forward, stuck out her tongue, and pressed it against Rachael's pussy. He gasped as it slid inside.
"Oh yes!" Rachael called out. "Fuck your little sister with your tongue!"
Allison obliged her, using her fingers to spread Rachael's lips and shoving her tongue in deep. Rachael's breaths, which had grown heavier and heavier, now came in gasps. Allison grinned, obviously enjoying giving her sister that kind of pleasure.
Then suddenly, she stopped and pulled out, causing Rachael to groan in dissatisfaction. "You're about to lose it," Allison giggled.
"Then let me lose it!" Rachael demanded.
"Don't be impatient," she playfully scolded. "You haven't even taken Greg's dick up inside you yet."
"Oh my god, Allison!" Greg gasped. "Are you really going to let me have sex with your little sister?"
"I don't care whether she lets me or not, I'm going to do it," Rachael said, climbing onto the bed. She swung one leg over Greg's waist so that she straddled him, her pussy directly above his cock. Allison grasped his member and pointed it up toward her waiting hole. She took her other hand and spread Rachael as Rachael lowered herself down onto his cock.
At the first contact, he groaned in ecstasy. She was so hot, so soft and wet. He couldn't help himself, but lifted his hips off the bed, spearing into her and causing her to gasp. She grinned, and pressed down even harder, and he felt himself sliding deep into her tunnel.
"That's right," Allison told him. "Fuck your sister-in-law. Fuck her long, hard, and deep. Shove it all the way up inside."
The words fueled his arousal, and he started to thrust even before Rachael was all the way down. As soon as she rested her full weight on him, though, she wasted no time but matched his rhythm. It felt so naughty to be having sex with a nineteen-year-old girl while his wife sat there watching, but as long as Allison didn't mind, he would take full advantage of it.
The sight of Rachael's hot little body bouncing up and down on his cock was almost too much for him. She was absolutely gorgeous. It was just too bad that he couldn't reach out and run his hands all over her, but on the other hand, the restraints added their own degree of excitement. The only thing he could touch her with was his cock, so he focused all of his energy there, spearing her almost brutally. She matched him with equal violence.
Then Allison climbed onto the bed. She straddled him above his stomach, facing her sister. She sat down, put her legs up over the top of Rachael's, and pressed their bodies together. The two girls kissed passionately as they held each other in a tight embrace, their tongues dancing together.
"Oh god!" Greg exclaimed as that erotic sight pushed him over the edge. He felt the pleasure mounting and knew he couldn't hold it any longer. "I'm going to cum!"
"Make sure you cum big," Allison told him. "Or you'll disappoint Rachael. Fill my sister full of your sperm."
He cried out as he felt the release. A wide grin spread onto Rachael's face as she felt him throbbing inside of her. That was enough to push her to the peak as well, and she nearly screamed as she climaxed. She thrashed about wildly, her hair flying all over. By the time she was through, her hair had fallen all over her face, completely hiding it from view.
Allison put her hand up and smoothed the hair away from her face, leaning in to give her one last kiss, this one more tender. "Are you going to take care of me now?" she asked her sister.
Rachael grinned and nodded. Allison lay back on top of Greg as Rachael climbed off of him. "You're going to love this part," Allison told him. Rachael lowered her body down until her head was at the level of his cock, which was still leaking cum. To his astonishment, she began to lick it clean. Although it had been growing soft, it suddenly firmed up again with the sudden stimulation. Rachael grabbed it and pointed it at Allison's pussy. Allison lowered her body onto it, letting it penetrate her.
As soon as it was inside, Rachael attacked both of them with her tongue. She licked them all over, from the base of Greg's shaft to the top of Allison's slit, paying particular attention to the point just where he entered her. Allison gasped in her breaths, especially when her little sister nibbled at her clit.
Greg couldn't believe what was happening. The sheer eroticism and forbidden nature of the act excited him beyond almost anything he had felt before. Here were two women, sisters even, stimulating each other and him at the same time!
When Allison reached an orgasm five minutes later, he did too. As his cum seeped out of his wife's pussy, her sister hungrily lapped it up. If he had been astonished before, that was nothing compared to what he felt now. Rachael apparently liked to eat cum. He wondered if she would ever give him a blowjob. He felt certain that if she did, she would swallow.
After it was all over, Allison rolled over off of him, and lay down next to him in the bed, her body pressing up against his. Rachael took a similar position on the other side. They didn't even bother to unchain him, which he found a little exciting. After all, he was still at their mercy, and they could do anything they wanted to him.
He was absolutely exhausted. The last time he had had more than one orgasm in a session was his wedding night with Allison; she had managed to get four out of him that night. Before that, he couldn't remember ever climaxing twice.
Allison reached out and put a hand on Rachael's breast. Rachael copied the motion, and Greg realized that they weren't through. It was too bad that he was too tired to enjoy it, but he liked to watch it anyway. He wondered if they would keep it up all night.
Unfortunately, he never found out. His exhaustion was so complete that despite wanting to enjoy the show, he felt sleepiness overtake him, and five minutes later he closed his eyes, not to open them again until morning.
