While Brit was in the den with Greg, Allison made her way up to Jeff's room to talk with Kari and him. "How are you feeling?" she asked Jeff, sitting down in an unoccupied chair.
"A little tired, that's all."
"And your head?"
"Just fine right now."
"Good. It breaks my heart to see you in pain. If there's anything I can do to help, just let me know."
"I will. Thanks."
Allison sat by him for a minute longer, as if she wanted to say something but was unsure about it.
"Jeff?" she finally said.
"Do you think you'll be up for a little... physical activity this weekend?"
"You mean like camping?"
"Actually, no," she replied, and he could see she was a little embarrassed.
"I don't understand."
She sighed. "I'm talking about spending time with Rachael."
"Exactly. There's just no stopping her when she sets her mind on something. And right now that something is you."
"Oh really?" asked Kari, raising an eyebrow.
"Exactly," Allison nodded. "Kari, I wanted to ask when you were here because I know Jeff would never go behind your back on things like this. I also happen to know that you're open to letting Jeff spend time with other girls in certain circumstances. Like your sister Crystal for instance."
"Good point," Kari shrugged.
"So what do you think?" asked Allison.
"But on the camping trip," Jeff replied, "there won't be much opportunity--"
"Actually, I was thinking of having you stay home from the camping trip."
"Stay home alone with Rachael?"
"Exactly. I was thinking, if you weren't feeling well enough to go to school tomorrow, then you probably wouldn't feel well enough to go camping."
"You actually want me to ditch school?"
"Just this once. You're not to do it any other time. I just think we need an excuse to leave you home. And since we can't leave you alone, you'll need an adult to stay here with you. Rachael never did like camping, so she would be the perfect choice."
Jeff laughed. Then he had a sudden idea. Lately, Allison's attitude toward him had changed. She seemed to be much more open about flirting with him, and she had lost control with him a couple of times. He wondered what had started it. Probably the kiss. She had seemed to enjoy it as much as he had. With her new attitude toward him, she might be open to a little fun herself.
"And what about tomorrow?" he asked.
"What about it?"
"While Brit's in school and Dad's at work, that leaves only you, me, and Rachael."
"Since you seem to have no problem watching Kari and me, I would think you wouldn't mind watching Rachael and me."
Allison grinned. "I hadn't thought of that. Good point. Now you're really starting to think with your dick."
All three of them laughed at that.
"Okay, I'll admit that it's tempting," she said. "Kari, it's really up to you."
She smiled. "I'll let you do it on one condition," she said.
"That I can come over on Saturday. I'm sure my dad will agree, especially since there will be an adult in the house to chaperone us."
"I don't think she's going to do much chaperoning," Jeff grinned.
"Oh, I think she's going to chaperone you all night," laughed Kari. "And then I'm going to chaperone you all Saturday. We'll both chaperone you till you beg for mercy."
As it turned out, Brit nearly ruined the plan. The next morning he pretended to wake up with a headache and sent Brit to fetch Allison and his dad. Rachael accompanied them as they entered his room. Jeff told them that he wasn't feeling well enough to go to school, and thought he had better stay home from the campout after all. Rachael immediately offered to watch him, since she really didn't like camping anyway. Unfortunately, Brit insisted that she remain home as well.
"I thought you liked camping," said Greg.
"But it wouldn't be as fun without Jeff there," she complained.
"A couple of weeks ago, you would have preferred it without him there."
"No, I wouldn't have. Even if Jeff and I would have argued the whole time, when there are only adults around it gets really boring."
Jeff suddenly thought of something unpleasant, though he wasn't about to bring it up. He should have thought of this before, when he had plotted with Allison. With Rachael and him staying home, that left Brit alone with Allison and Greg. And that was exactly the same combination of people that had been on that sailing trip that summer, except with Brit in the place of Lissa. Was she afraid of something like that happening to her? Despite those pictures, Jeff couldn't quite see his father as a child molester, but he could definitely see how Brit might be a little fearful. He suddenly pitied her.
"I wouldn't mind Brit here to keep me company," he said.
"Well, maybe we should cancel the whole trip," Greg suggested. "It was supposed to be a family outing."
This was getting dangerously close to having the whole plan fall apart. Brit's presence might complicate things between him and Rachael, but at least she could be sent to bed early. But if everyone stayed home, the whole weekend would be ruined.
"I don't want that on my conscience," Jeff insisted. "I feel bad enough as it is. Why don't you and Allison just go and have a good time?" he said. "We can do it again some other time, after I'm feeling better."
"But it's getting late in the year. We probably won't have any more chances to go camping together."
"So then it's especially important not to cancel this one. Just go with Allison. It doesn't bother me, really."
Allison flashed Greg a hopeful glance. "I really wouldn't mind spending some time alone with you," she told him. "I haven't had you to myself in a while."
"But the kids--"
"We don't mind at all," said Brit. "Jeff thinks it's okay if you two go by yourself, and remember, I volunteered to stay home."
Greg glanced at Allison, then back at the kids. "As long as you won't feel left out, I suppose it's all right."
Jeff felt a surge of relief. His fun wouldn't be spoiled after all.
Greg and Brit had barely left the house when Rachael came up to his room and pounced on him. She attacked him with her lips, and he was more than happy to let her. She had her shirt and bra off and was working on her pants when Allison appeared in the doorway.
"Slow down, Rachael," said Allison. "He hasn't even gotten out of bed yet."
"That's the point," Rachael grinned.
"At least let him have some breakfast first. He's going to need to keep up his strength."
"Yeah, I guess you're right. Come on, Jeff. Let's go eat." Without putting her top back on, she took his hand and half dragged him out of bed.
The three of them descended the stairs and headed into the dining room, where the they found pancakes, bacon, eggs, and orange juice all ready. Jeff took a seat, and Rachael came and sat down on his lap, painfully mashing into his erection.
"Hey!" he said, though with a smile. He squirmed around until achieving a position where the pressure was relieved.
"What?" asked Rachael. "You've had Brit sitting on your lap all week. I was getting jealous."
"You're bigger than she is."
"Certain parts of me, at least," she grinned. "So tell me, Jeff, do you like big boobs like Allison's and mine, or little boobs like Brit's?"
"I'm not in the habit of peeking at her boobs," he replied. While that was technically true, he had seen her naked before. He wasn't about to tell Rachael that though, especially with Allison there.
"Okay, I guess that's fair. Just tell me, do you get as hard down there when Brit sits on your lap as when I do it?"
"No!" he said, growing red.
"Oh come on, Jeff. You can tell Auntie Rachael. You already admitted you think she's hot."
"I just meant that she's a very attractive girl for her age, that's all. There's nothing wrong with that."
"And there's also nothing wrong with getting aroused when an attractive girl sits on your lap."
"You really have a dirty mind, Rachael," he laughed.
"Just figuring that out now? Took you long enough."
The two of them ate breakfast together, Rachael of course continuing to flirt the whole time. Jeff was anxious to get on with the day's activities, but because Allison was taking her time, he decided not to forgo seconds on the pancakes.
After breakfast, Allison insisted on putting the leftovers in the fridge first, as well as loading the dishwasher. Jeff suspected she was doing it to tease him, drawing out the anticipation as long as possible. He didn't mind as long as Rachael made it up to him later.
Finally the three of them headed into Greg's and Allison's bedroom. While Rachael wouldn't have minded using Jeff's, the master bedroom was larger and cleaner.
Rachael was out of her clothes before Jeff even had his shirt off. Then she offered to help him undress the rest of the way, to which he happily agreed. She knelt down on the ground in front of him and pulled down his boxer shorts, finally releasing his cock. She grinned when she saw it.
"I think it's even bigger than last time," she said. "I'm really going to enjoy this." She opened her mouth and wrapped her lips around it.
"Oh god!" he moaned as the pleasure hit him.
Unfortunately, she only gave it a few preliminary sucks before letting it slip out of her mouth and rising to her feet.
"We don't want you to go off too soon after all," she said. "We have all day. I just wanted to see if it tasted as good as I remembered."
"Did it?" asked Allison.
"Even better. At this rate, in a few years it's going to taste like ice cream."
Jeff chuckled. He was more than happy to let Rachael taste it as much as she wanted. If only he could get Allison to do the same...
"Wouldn't it be more fun if you were naked too?" Rachael asked her sister.
"Probably, but I made a promise years ago that I wasn't going to cross that line with Jeff," she replied.
"Apparently having him naked with you wasn't part of that promise."
"Exactly," Allison grinned. "And Jeff doesn't mind, do you, Jeff?"
"Not a bit," he smiled. "Although I have to admit, I'm kind of disappointed that it isn't more of a hands-on experience."
"Oh, I can take care of that," Rachael said, grabbing his cock. "But anyway, Allison, I know that you've worn a bikini in front of him before, so that much (or that little, I should say) shouldn't bother you."
Allison considered. "Oh, all right," she replied. "I'll go get changed."
"We'll wait for you," said Jeff.
"Speak for yourself," Rachael grinned, sliding her hand up and down his shaft. "Better hurry, Allison, or the show might be over by the time you get back."
While Allison rummaged through her dresser drawers for the bikini, Jeff and Rachael climbed into bed. They lay there next to each other, kissing and groping. Rachael's hand immediately went to his cock and she started to stroke it, slowly and gently. Jeff put his hand on one of her breasts, rubbing and squeezing it.
Allison found the bikini and headed into the bathroom to change, leaving Jeff and Rachael to play with each other. He could hear her shuffling around in the bathroom as she undressed, but his more immediate attention was on Rachael. The girl was so gorgeous and sexy, and she was naked with him in bed right now. He wasn't going to pass up this opportunity.
After a few minutes, the bathroom door opened. Jeff glanced over and grinned. Allison stood there, wearing that tiny little bikini that she had nearly seduced him in earlier that week. It was very sexy, showing plenty of skin in all the right places.
Rachael seemed to enjoy it too. "God, Allison!" she said. "You're so hot. Come over here and join us."
Allison climbed onto the bed, lying down on the other side of Rachael from Jeff. She reached out and placed her hand on her little sister's breast. Rachael gasped, and not surprisingly, so did Jeff.
"I just realized something, Allison," said Rachael. "Jeff's never seen us perform."
"True, but I'm not about to do it in front of him. Remember my promise."
"You only promised not to let him see you naked. You can still ravish my body with your mouth. What do you say, Jeff? Wouldn't you like to see a nice lesbian incest show?"
"You bet!" he grinned.
"Oh, all right," conceded Allison. "But Jeff, you have to promise to behave yourself. No touching."
"He can touch me all he wants," said Rachael.
"All right. Jeff, you can do anything you want to Rachael, but I'm off limits, okay?"
"Good enough," he replied.
Jeff moved to the side to give Allison room to work. His stepmother climbed over on top of her sister, then lowered her body and kissed her passionately on the lips. Jeff's eyes opened wide and his heart began to pound. He was actually going to see Allison engaging in hot lesbian sex! And with her sister even. He couldn't believe the thrill this was giving him.
The two women continued to kiss, their bodies pressed against each other. Rachael wrapped one of her hands around Allison and let it rest on her ass, while she reached out with the other and took Jeff's cock in her hand. Jeff lay on his back to make it easier for her to stroke it.
Both of the women were getting into it now. Their tongues sought out each other's mouths. Allison smiled with contentment as Rachael kissed her, and Jeff could see that she was starting to rub her breasts against her sister's. Rachael sensed the motion and giggled.
After a few minutes of kissing and rubbing, Allison moved down slightly and began to lick her tongue against Rachael's neck, causing the younger sister to squeal with delight. Jeff remembered that was a trick Rachael had taught him the first time they made love. He would have never figured out on his own that a tongue on the neck could feel so erotic. It gave him shivers just thinking about it.
But Allison wasn't finished. She moved lower, kissing her sister on the collar bone and just below the shoulders. As she did so, she slipped her hand down between the girl's legs. Rachael spread her legs for better access, closing her eyes and breathing heavily.
Allison moved her head off to the side, kissing her in a straight line down her chest to one of her tits. Rachael began to moan now from the stimulation. It was such an erotic sight, Jeff just couldn't resist. As Allison took one of her sister's nipples into her mouth, Jeff leaned over and took the other one into his. Rachael cried out in pleasure.
They teased her breasts like that for at least ten minutes, listening to Rachael's breathing as it grew heavier and heavier until she gasped every breath. Her chest expanded as she inhaled, thrusting upward as if trying to drive her body into their mouths. Jeff and Allison got a rhythm going, beginning the suction just as Rachael was about to breathe in, and releasing the pressure as soon as she began to exhale.
Jeff loved to do this to girls; their reactions were extremely erotic, and he loved the feel of the nipple inside his mouth, especially as he toyed with it with his tongue. Rachael had gorgeous breasts, just perfect for sucking on.
"Take over," Allison told him, grabbing his hand and placing it on Rachael's other tit. Allison began to kiss her way down the underside of it, then toward her stomach. Rachael knew what was coming, and she moaned in anticipation, her mouth open wide in a smile. Jeff continued his work on her chest, suckling one breast while he fondled the other. He turned his head so that he could view the action going on below.
His stepmother was kissing her sister all over the stomach, sometimes up at the base of the sternum, sometimes just above the clitoris, and everywhere in between. Rachael's hips tensed up each time Allison neared her cunt, but Allison deliberately kept her distance.
Jeff knew what she was doing. He had discovered the same thing with Kari: the anticipation helped to build the pleasure so that when the physical stimulation actually came, it was all the more intense. Whenever he performed oral sex on her, he did almost exactly the same thing. He could sometimes bring her to multiple orgasms without even touching her pussy.
Crystal was different. She needed direct physical stimulation to climax. That could mean either Jeff's dick shoved deep inside her pussy, or Kari's tongue on her clitoris, or preferably both.
Finally, after what must have been an agonizing time for Rachael, Allison reached her goal. Rachael cried out in ecstasy and her hips bucked forward as her sister tongued her. She thrashed around on the bed almost violently. She grabbed the back of Allison's head and pulled her down, wrapping her legs over her shoulders. Her moans rose in pitch until they were screams.
After a few minutes, she began to calm down again, releasing Allison and relaxing. Jeff figured she must have reached her climax, though she had obviously been in the throes of ecstasy the whole time.
Allison lifted her head up and smiled at the two of them. Jeff rolled over until he lay next to Rachael on the bed, and Allison scooted up to lie on her sister's other side.
"So what did you think, Jeff?" asked Allison.
"That was incredible!" he breathed. "That's one of the most erotic things I've ever seen in my entire life."
"And now it's your turn, Allison," Rachael grinned. "I'm going to make you feel every bit as good as you made me feel."
"And just how do you plan to do that without me taking my clothes off?"
"Oh yeah," said Rachael. "Good point. Are you sure we can't change your mind?"
"Jeff's my stepson. I'm not going to let him see me naked."
"Okay, Jeff, turn around," said Rachael.
"Oh very funny," laughed Allison.
"What? Don't you trust him?"
"Of course I don't."
"Hey!" Jeff exclaimed.
"Sorry, Jeff," Allison apologized. "It's nothing about you personally, but you're a teenage boy, and that means that there's no way you would be able to stop yourself from peeking on a couple of lesbians having sex right in your presence."
"Plus if you're turned around, she won't be able to stare at your cock and fantasize about it being shoved up inside of her instead of my tongue," Rachael added.
Surprisingly, Allison laughed instead of growing red or getting angry. "You really have the most twisted mind of anyone I've ever met," she said.
"Easily. But I don't want you to lose out. We just need a way to keep Jeff from seeing us, some way that he won't be able to peek. Oh, I have it!" she exclaimed with excitement. "It's a little kinky perhaps..."
"Never stopped you before," said Allison.
"We just need a chair, a long piece of cloth, and a couple of pieces of rope."
"Oh my god!" Jeff said. "You're going to tie me up and blindfold me?"
"I promise I'll make it worth your while," Rachael told him.
"I don't know... It does sound kind of fun, but I'd be a little nervous."
"Don't you trust us?"
"You, no way," he grinned. "I know how much danger turns you on. But I suppose I trust Allison enough."
"So you don't mind?" asked Allison.
"Mind? Of course not. As long as Rachael makes good on her promise to make it worth my while."
"Oh, I will, believe me," Rachael laughed. She grabbed a wooden chair from the desk in the corner and brought it over to face toward the bed. "What can we use for a blindfold and rope?" she asked.
"I've got an old scarf," Allison replied.
"And there are some pieces of rope in Brit's room that are the right length," Jeff commented.
"Oh?" Rachael grinned. "Do you like to tie her up and have your way with her?"
"She's my sister!"
"That never stopped Allison and me. Remember when we used to do that to each other, Allison?"
"Do I ever! I always liked to be the one that got tied up."
"You two are really too much!" Jeff laughed.
"Actually, Greg told me something amusing," said Allison. "It seems that Jeff and Brit do have a little bondage thing going sometimes."
"What are you talking about?" Jeff demanded.
"Don't play innocent, young man. Sometimes when you're really in a sadistic mood, you tie little Britney to her bed, don't you?"
Rachael laughed out loud. "Oh my god, really?" she asked.
Jeff felt himself blushing. While it was technically true, there was nothing sexual about it at all. It was mean, admittedly, but it was just two kids playing around. Besides, he hadn't done it to her in years. That last time he had even threatened her with it had been over a year ago.
"That's different," he insisted. "I only do it when she deserves it, and only to tease her."
"Bondage and teasing," grinned Rachael. "Sounds fun. Maybe we can play that game with her tonight."
"No way!" he said. "If I know you, you'll take things too far."
"He's got a point," said Allison.
"Okay, fine," Rachael conceded. "We'll just have to settle for having wild and kinky sex in front of her. But anyway, we've been talking too long. Let's get you all tied up and blindfolded so Allison can get out of those stifling clothes."
Jeff had never thought a bikini could be considered 'stifling clothes,' but he certainly wasn't going to argue the point. He headed upstairs to Brit's room to retrieve the ropes that he used to tie her up. When he returned downstairs to Allison's and Greg's bedroom, he found they had already set up a chair in the corner.
"Have a seat," said Allison, taking the ropes from his hand. He immediately sat down in the chair, placing his arms and legs in position.
Allison thoughtfully retrieved some handkerchiefs from her dresser to minimise the chafing on his skin. The women set to work wrapping the ropes around his arms on the armrest, and his legs with the chair legs. He felt excited by the closeness of the two girls as they worked, chills running through him every time Allison touched him. He could feel the warmth of both of their bodies as they bound him, naked, to the chair.
After they secured him, Rachael stepped behind him and placed another handkerchief, rolled up, over his eyes and tied it behind his head.
"How's that?" asked Allison.
"Great," he said, testing the tightness of the ropes.
"Are you sure you can't see anything?" asked Allison.
"Nothing," he replied.
"And your arms and legs are securely fastened?"
He tried to lift first one arm, then the other, then each of his legs in turn. There was no way he could get free.
"Perfect," Allison said. "Now it's time for me to finish undressing."
"Wait a minute," said Rachael. Jeff could hear her moving around behind him. He suddenly felt her arms over his shoulders, running down his chest. She began to massage him.
"Come over here," Rachael suggested, and he could hear Allison stepping forward. "Closer," Rachael insisted. "Come right up to the front of the chair."
Allison followed her sister's instructions, and a moment later he felt her soft legs against the insides of his knees. This close, he could feel the warmth of her body less than a foot from him.
"Now strip!" Rachael ordered.
Jeff could hear Allison moving around, and he imagined her standing there naked, so close to him. If only he didn't have that blindfold! But then, without the blindfold, Allison wouldn't dare do this.
Something soft brushed against his cheek, and for a moment he wondered what it was. It felt like it was made of cloth and string and...
"God I love your tits!" Rachael breathed, and Jeff suddenly realized, it was Allison's bikini top. That meant she was topless in front of him. His heart began to pound in his chest.
Allison giggled, then removed the garment from his face. He couldn't believe she was doing this, actually getting naked with him!
A moment later he felt something else soft on his cheek, and knew it must be her panties. So she was completely nude now, and standing right in front of him. He couldn't believe his fortune, but at the same time, cursed the blindfold that kept him from seeing her in all her glory.
"Okay, Rachael, are you satisfied?" she asked.
"Beautiful," her sister sighed. "It's just too bad Jeff can't see this. But you've got an imagination, don't you Jeff?"
"I don't think it's possible for my imagination to compete with the real thing right now," he grinned.
"Why don't you give him something else to fuel his imagination?" asked Rachael. "Give him a kiss."
Allison was silent for a moment. Then she said, "Do you mind, Jeff? Does my baby boy have a kiss for Mommy?"
So it was back to this game then. He didn't mind; on the contrary, it was deliciously naughty. That meant Allison was in the same mood as yesterday, and he wondered just how far she was going to take it this time. The fact that he was tied up and helpless made it even better; it meant that whatever she did, it would be what she wanted.
"Come kiss me, Mommy," he smiled, and puckered up.
From the moment he felt her lips on his, he was in paradise. She put her hands to the side of his head, holding him there as she kissed him with passionate abandon. As one, they opened their mouths, and he felt her tongue slide in to toy with his own. It was the most un-motherly kiss he had ever felt.
"Did you like that?" she asked as soon as they broke the kiss.
"Oh my god, Allison!" he gasped. "Yes!"
"Be a good boy and maybe I'll give you a reward later," she teased. She put a hand on his cheek and stroked it for a second, then slid it down to his neck, then his chest, then his stomach. Jeff groaned as she took it away just at the last second.
"Come on, little sister," she said. "I want to feel that tongue of yours shoved up my cunt."
Jeff shuddered at that mental image. Now he really wished he could see. He had to be content to listen as the women climbed onto the bed. He could hear the sounds of them kissing, perhaps a little louder than absolutely necessary, but of course Rachael at least would exaggerate the sounds to tease him.
Interspersed with the kissing noises were moans and giggles as the two girls toyed with each other. He tried to imagine what was going on from the sounds, but they were generic enough that the girls really could be doing anything.
After a few minutes, the sounds changed. There was less from Rachael and more from Allison. His stepmother was breathing deeply, and her moanings became more sustained, no longer just short hums.
"What's that?" asked Rachael suddenly. "Wait a minute, Allison. I'm not done with you."
Jeff wondered what was going on. He wished he could see, but the blindfold kept him completely in the dark.
"Hey, where are you going, Allison?" Rachael asked again. "Oh my god! I thought you didn't want to do things like that to Jeff!"
He gasped as the implications of her words hit him. Did that mean that his stepmother was about to...
"Sorry, Jeff," said Rachael. "I've seen that look in her eyes before. There's no stopping her when she gets in these moods. You're just going to have to suffer through it. If 'suffer' is the right word."
"What are you talking about?" he asked.
Then he heard someone shuffling across the floor toward him, probably on her knees. A pair of hands suddenly touched his thighs, and he jumped. Then there was another sensation: a warm, soft, wet feeling at the tip of his cock.
"Oh my god, Allison!" he exclaimed as he realized what was happening. Her lips closed about his member and he felt her begin to suck.
He moaned as she moved up and down the shaft, taking as much in as she could and then sliding back until she had only the tip between her lips. She repeated the rhythm over and over and over again, sucking it hard and deep.
Jeff couldn't believe what was happening! Only in his wildest fantasies had she ever done this to him, and now it had become real. Allison, beautiful Allison, was pleasuring him with her exquisite mouth!
"Oh shit!" he shouted. "Oh Allison! Don't stop! Keep going!"
She giggled as she heard him call out like that, but she didn't break her rhythm. Although he couldn't see her with his eyes, he imagined staring down at her, gazing into those big, beautiful, lust-filled eyes over her sweet red mouth wrapped around his cock. The image was beyond erotic.
His helplessness only served to heighten his arousal. Unable to move, unable to resist, he knew it was all her own choice. She wanted this as much, if not more, than he did. No, that was impossible; nobody wanted this more than he did. But just the thought that she was taking him without giving him the chance even to say no felt wonderful. Not that he would have said no; it was just the thought that it was all her doing and none of his own.
Her hands weren't idle during this time either. She began to massage his hips, running them all over his lower body to stimulate the entire region. She sought out his balls, running her fingernail lightly over them to tickle them. That only increased the stimulation and the pleasure.
She drew back once more and stopped, her lips wrapped tightly around just his head. She sucked in as hard as she could, though keeping only the end of his cock in her mouth. Then he felt her tongue dancing across the tip, driving him even wilder with lust.
He had given up on words and was now just moaning with animal passion as she tickled his balls with her fingers while she teased his dick with her tongue. Even Kari had never been able to give him such intense pleasure. Allison was so skilled at what she was doing!
He couldn't stand it any longer. He had to find release. As his cock swelled, she sensed his need, and suddenly jammed her face forward, impaling her throat on his cock. He screamed as he let it go, and she hungrily gulped it down, moaning her delight as he shot load after load straight down her throat.
He was in absolute ecstasy, not only because of the intensity of the pleasure, but also from knowing who was giving it to him.
"Allison!" he cried out. "Allison! Allison!"
The end was almost a relief when it came; the pleasure had so completely overwhelmed him that he almost passed out. As he gasped in air to soothe the pounding of his heart, his head flopped forward in exhaustion. Only when she was sure that he had given her all he had did she let his cock slip out of her mouth.
"Okay, you've had your fun, Rachael," came Allison's amused voice from across the room. "I'd appreciate it if in the future you didn't cause my stepson to call out my name in the height of passion."
Jeff began to laugh, though weakly. Of course. He should have known. Maybe it was because he wanted it so badly that he had allowed himself to be fooled. But naturally Allison wouldn't have done this to him. Rachael, on the other hand, loved a good joke, especially one as dirty as this.
"Sorry, Jeff," Rachael apologized from between his legs. "I just couldn't help myself. It was just a sudden idea that popped into my head, and I had to go with it."
"You're such a naughty girl," he grinned.
"Does that mean you're going to punish me?" she asked excitedly.
"I'm the one tied to a chair, not you," he replied with a laugh. "Maybe you should be punishing me."
"Tempting," said Rachael, "but I still haven't finished taking care of my sister."
He heard her moving away from him, then back onto the bed. For a few minutes there was mostly silence punctuated by little gasps or tiny moans from his stepmother. Those sounds increased in frequency and volume, though, and Jeff could imagine Rachael's lips and tongue running all over Allison's body. While his recent orgasm kept him from growing hard again, he shivered at some of those mental images, especially when they were reinforced by the sounds coming from the bed.
A few minutes later, Allison sucked in her breath with a gasp, then let it out with a long, ecstatic wail. Jeff could hardly believe he was listening to her having an orgasm! There was something intensely satisfying about that sound coming from her. An orgasm was, in a sense, a loss of control. It was the body being overwhelmed by physical stimulation. Allison had always been such a powerful woman, always so self-confident and sure of herself. She was a woman far out of Jeff's reach. Now, listening to her lose herself in an orgasm showed another side of her, a more human side. She was capable of being consumed by her passions and desires, of losing control and loving it. While it didn't weaken her at all in his mind, it made her seem more approachable.
"God, Rachael, that was wonderful!" she breathed as she lay panting there afterward.
"Nothing's too good for my big sister," Rachael replied.
They lay there for a few more minutes. Now that the fun was over, Jeff felt anxious to get untied. He tried to be patient; he knew how exhausting sex could be, and wanted to give the girls a chance to recover.
Then he heard them moving around on the bed again, then it sounded like at least one of them is getting off.
"I think it's time for me to start making lunch," said Allison. "After what the three of us have been through, we need to recover our strength."
"So aren't you going to untie me?" asked Jeff.
"I don't know," said Rachael. "Maybe we ought to leave you here. Brit will be home in a few hours, and maybe she'll want a chance to get her revenge for all those times you tied her up. Then again, maybe she'll want to join in on the fun."
"More likely she'll run away screaming," he laughed.
"Well then I'll just have to tie her to a chair too. Then I'll have my way with her."
"Oh, I'm sorry. I didn't know you wanted to do the honors."
"Hey! She's my sister!"
"That never stopped Allison and me."
"Oh. Um..." He really had no response to that.
Despite her playful threats, he felt hands fumbling at the ropes on his left wrist. A moment later he was free. He immediately took off the blindfold. To his disappointment, Allison had disappeared into the bathroom already to put her clothes back on. Fortunately, Rachael was still completely nude, and as soon as she finished untying her, he grabbed her and plopped her down on his lap, then gave her a long, deep kiss.
"Maybe I should tie you up more often if it gets you into that kind of mood," Rachael said with a wink as soon as she pulled away.
"I'm always in that kind of mood when you're around," he told her.
"You're making me horny. You know, we never did get to finish what we started earlier."
"Sounds good to me," he said, and they moved to the bed.
Allison reappeared then, still in that bikini. "Still going?" she asked with a grin as she saw them kissing and fondling.
"We're going to keep going all day," said Rachael.
"Well, I need a rest," said Allison. "An old lady like me can't keep up with youngsters like you."
"You're not old!" Jeff exclaimed.
"Thank you dear," she smiled, then climbed onto the bed and lay down next to him. He rolled over onto his back, and both girls began to massage his chest. Rachael kissed him on the lips, then when she drew away, Allison took her place.
Jeff sighed as the two sisters continued to rub him and kiss him, suddenly feeling very relaxed. He was still a little tired from the blow job a little earlier, so he closed his eyes and let the girls take care of him. Although he wanted to stay awake, he fell asleep to the wonderful feeling of their soft, gentle hands all over him.
He groggily opened his eyes and glanced around the room. His stepmother lay cuddled against his chest, with her sister's body pressed up against her back. Allison still wore the bikini, while Rachael wore nothing.
Allison yawned, then glanced up at him with a smile. "I guess we all fell asleep," she said. "You were the first one, and of course it had to be one of those episodes where we couldn't wake you, so Rachael and I decided to take a nap too."
"After raping you in your sleep of course," Rachael added, opening her eyes. "That's all right, isn't it, Jeff?"
"Only if the next time you rape me you do it when I'm awake," he grinned.
"Take that up with Allison. It was her idea. I couldn't believe how many times she fucked you. Probably from three years worth of pent-up sexual frustration at living with you but not being able to lay a hand on you. But she made up for it today, believe me."
"She's kidding of course," Allison told him. "I only took my top off and rubbed my tits all over your body."
Allison burst out laughing. "I'm sorry, I just had to see your reaction," she grinned.
"Tell her what we really did," said Rachael.
"Well, you know how Rachael has a thing for dangerous sex? You know, doing it in places where you could end up getting caught?"
"Well, she insisted that I get naked with her so we could do it right on top of you."
"Holy shit!" Jeff exclaimed.
"All you had to do was open your eyes, and you would have seen your stepmother in all her glory, getting eaten out by her little sister as she lay on your chest. It was too bad you were fast asleep. Next time you ought to fake it."
"You know, I'm feeling suddenly very sleepy again," Jeff grinned, then closed his eyes and began to snore loudly.
"Nice try," said Allison.
"Dang!" said Jeff. "Oh well."
"Anyway, it's almost three o'clock," Allison told him. "Brit should be home pretty soon. We'd better get dressed."
"Why should the three of us get dressed?" asked Rachael. "There are three of us and only one of her. Make her take her clothes off instead."
"Very funny. Come on, Jeff. Imagine her reaction if she sees us lying nude on the bed."
"She'd probably run away screaming," he laughed. "That would be hilarious. Maybe we--"
"Don't you dare!" Allison grinned.
Jeff sighed, reluctantly climbing off the bed to go put his clothes back on.
