Chapter 1

During the course of two weeks, Danny matured rapidly. His mother was to thank for that. Carol loved to dirty talk whenever they made love and it proved to help quicken Danny's knowledge of sexual terms. He was still just a boy, but one who understood more adult natured themes than most kids his age and older.

The alarm went off at six o'clock in the morning. It was the morning where Susie was to be picked up from the airport. Carol was nervous of course, her daughter was only 13 after all and traveling alone. Luckily no plane switching was needed and each time someone was there to drop Susie off at the gate as well as pick her up, but Carol was a mother and naturally worried for her children, but she was also nervous for reasons not so obvious.

Susie went to Colorado to visit her best friend Krista for the summer. Susie and Krista were the same age, birthdays in the same month, and only up to a few years ago, grew up together in the same neighborhood, but when Krista's father was promoted they also had to move.

As far as Susie knew, seeing her best friend again was the only reason why she was sent there, however the adults, Carol and her best friend Sarah as well as Sarah's husband Ron, had ulterior motives. It's a long story with much history, but the short version was that Sarah's and Ron's marriage was growing dull and sex became mundane. In turn, without intent, they both began to develop sexual feelings for their daughter Krista. They acted on their feelings; manipulating and playing their daughter in hopes to subtlety create those same feelings in her. Eventually they succeeded and it was Krista who made the first real move towards her father.

Carol, who at the time also developed perverse feelings towards her own kids, knew all along. There wasn't anything her and Sarah couldn't tell each other. They became like sisters when they met 13 years ago. Both were pregnant in their teens and met in a support group specifically for that reason. When Sarah made the call to Carol to inform her that Ron just popped Krista's cherry, they were both thrilled. Not the typical reaction when told that a 13 year old just lost her virginity to her own father, but one that both Carol and Sarah shared.

So a plan was hatched during that phone call. A plan to get Susie's cherry popped. Sarah and Ron wouldn't force her or even pressure her; they would similarly manipulate her and use Krista to help. Afterwards, they'd have her sent home believing she could seduce her own family and continue her sex-apede. That was important though, Susie had to do the seducing. She had to believe she wasn't being played. She was of course, but if she were to find out, that could break any form of trust.

The plan didn't end there, but extended to involve Carol. If Ron and Sarah were able to get Susie to agree and did in fact sleep with her, then Sarah would call Carol the moment it happened and Carol would then play the part in seducing her son.

Carol reached over to turn off the alarm. "Alright Danny, time to get up." The morning was warm and the sun light was already starting to peek through the window. With a grunt, Danny got up. He wasn't as excited to see his sister as Carol, but he was still excited enough to actually get out of bed without a fuss; that would be an accomplishment on any other day.

"Mom, do we really have to hide what we're doing from Susie?" Last night before they slept, Carol talked to Danny about keeping the fact that they were sleeping together secret from Susie.

"We do. Not another word about it Danny. If and when the time comes, I'll tell her."

"But."

"No but's. I'm still your mother and you're still my son and you will listen to me. Understood?"

"I don't understand, but fine."

Carol let out a sigh, "Trust me Danny. It'll all work out. I know you want share what we have with your sister, but you just have to trust me."

"I trust ya."

"Good." Carol walked over to Danny and gave him a big hug. "Now go get dressed. We'll hit a drive through for breakfast on the way there."

The entire morning Carol was anxious to see her daughter. Susie left home a carefree and innocent little girl and would return a woman. Carol knew Susie had sex with Ron at least once, but any her knowledge never extended past that. Sarah kept it a secret; she wanted it to be a surprise. Sure Carol had ideas. She was pretty sure Susie had sex more than once, but did Sarah join in? Did Krista? The thought of Krista, Susie, together, naked, exploring their body's, Sarah instructing them, it was a good thing Carol decided to wear a skirt, her panties were soaked and would've shown through any pair of pants. Carol wasn't always bisexual, but when Sarah (who was bi since before they became friends) finally convinced her to try it, she discovered how hot it was, how much it turned her on.

When they arrived at the airport, it took Carol all she had to try and contain her excitement. She felt like hopping and being giddy as she waited for the passengers to come through the gate. "Mom, are you alright?" Danny could tell his mother wasn't acting her usual self.

"I'm fine Sweetie. I'm just excited to see your sister. I haven't seen or spoken to her in all summer."

"I'm excited too." Carol wrapped her arm around Danny's neck and held him close to her. People finally started coming through the gates, "Do you see her Mom?"

Carol didn't say anything, she held onto her son as she used all her focus to try and spot Susie amongst the crowd of people. And there she was. The moment Carol saw her she yelled out, "Susie!"

Susie looked just like her mother when she was her age at 13; young, pretty, sparkling emerald eyes, and an adorable smile. She stood at around 4'4''. Her hair was light auburn, sure to turn a darker shade as she grew. It went below her shoulder when she let her hair down, but often she liked it in a wide ponytail with braids and cute bangs. She was wearing a yellow sundress spotted with sunflowers and with a belt wrapped around just above the waist to show off her curves. "Mom!" Susie ran over to her mother.

Carol knelt down to embrace her daughter in a hug and lifted her with a squeeze as she stood up. "I've missed you SO much!" Carol kissed her cheek.

"Mom!" Susie exasperated embarrassingly as Carol put her down.

"Hey Susie." Danny interrupted.

"Danny! I didn't see you there!" Susie went over to hug her little brother and he hugged her back. "So how've you managed without your big sister?"

"Fine. Haven't even noticed you were gone." Danny retorted.

"Liar. Admit it, you missed me."

"Not in the least bit."

The way Susie was acting surprised Carol. She wasn't any different. "Okay you two. Lets' go get your luggage Susie and head home. Might stop somewhere on the way and get something to eat." Carol gave Susie another hug, "So glad you're back home Baby!"

Chapter 2

During the ride home and while in the restaurant, Carol did notice something. Susie kept shifting or more so she really could never quite find a comfortable position when she was sitting. Even Danny said something, but Susie passed it off as a joke.

When they got home Susie went upstairs to unpack. Danny walked over to his mother and whispered, "Mom, are we still going to have sex even with Susie back home?"

"You ask me that now with Susie back home and not before?"

"Well I just assumed we were, but you acted so normal when she was around that I suddenly felt afraid we weren't anymore."

"Honey." Carol hugged her son, "Honey listen. We might not, but only for a little while!"

"How long would we have to wait?"

"I don't have an answer for that, but remember Danny, you have to trust me. Okay?"

Danny let out a sigh. Not being able to show his mother the affection he felt was tortures. "Okay."

"Thank you for understand Danny. I'll make it up to you, but right now I need to make a phone call." Danny nodded and went upstairs. Carol had an idea what for.

The cellphone in hand, Carol dialed Sarah's number. Someone picked up and a chirpy voice answered, "Heya Carol!"

"Sarah, hi."

"Everything okay?"

"Of course, I just wanted to tell you Susie arrived and we all made it back safe."

"That's good. How is she?"

"She's...normal. Not acting any differently."

"All part of the plan. She'll open up, her legs that is, soon enough."

"Sarah!" Carol laughed.

"I'm kidding, I'm kidding, but kind of not either."

"Well, either way, what happened over there?"

"Many things. Many kinky things. In fact, are you sure she hasn't been doing ANYTHING out of the norm since she got back?"

"Well, I didn't think anything of it at first, but now that you mention it, she has been odd in not being able to find a comfortable position." Carol continued, "Even Danny has said something to me. She keeps leaning forwards, standing up and rearranging her dress. I've even seen her sitting on her hands a couple of occasions."

"And why do you think this is?"

"Seriously Sarah, tell me."

Sarah let out a devious sound, "Butt plug."

"What?"

"Butt plug. She's wearing a butt plug."

"My little Susie is wearing a butt plug? She was on that plane for hours!"

Sarah let out the same devious sound, "I know. Don't get me wrong, it's a small one, well more like a medium small one."

"Why would she agree to something like that?"

"Carol, your daughter agreed to so many things. Don't worry though, it's perfectly safe. I told her to pull it out once she arrives home, so I imagine that's what she's doing now." Sarah started trailing off. "Pulling it out of her sweet...I'm sorry Carol. I need to find Krista. Now. Talk to you soon, bye!"

After Carol hung up she too began thinking of her little Susie having a small dildo up her ass. It was something Carol certainly never tried. Being a single mother of two and receiving no child support, Carol didn't have much of a sex life. Ass play was just something no one talked about while she grew up and having an assortment of plastic lovers, she only stuck with what she knew.

Sarah on the other hand only had one child and her husband wasn't a selfish coward. They did their best to keep things interesting in the bedroom, anal sex was among the crazy things they did. Carol thought of all the wild things Sarah told her that she and Ron have done to keep the flame going and that her Susie was being taught how to fuck by these people. The image of Ron's eight inch cock demoralizing Susie up the ass flashed in Carols mind. She wanted to just forgo the plan, run upstairs, and fuck her daughter mad! "Easy girl. Give her time." Carol said to herself. "Fuck that!"

Chapter 3

During the time Carol was on the phone, Susie was upstairs following Sarah's instructions. She wasted no time. It wasn't Carol who Susie was to 'seduce' first, but her little brother Danny. The way Sarah told her, "Have him catch you doing something sexy, if he doesn't look away or make himself known, you have him." Susie knew how to do just that.

While Danny was still downstairs, Susie went to her bedroom. She made sure her room was the only room to have light on. Danny's room was next to hers, so he would have to walk by her. She kept the door slightly ajar, leaving an opening large enough to see into a corner of her room.

Susie undid her belt, slipped the spaghetti strap off her shoulders making her dress fall. She looked over at the mirror and could see her door in the reflection. If Danny were to peak in she would know. Susie started looking over herself in the mirror. During her time in Colorado, Susie gained a lot of confidence through her body. She had no bra on, revealing her small (not entirely developed) breasts and puffy pink nipples. Her butt cheeks were hugged tight by white cotton panties and her mound was wet. Susie would stand here until her brother found her.

It didn't take long. Susie quickly heard the pitter patter of feet running up the stairs. She heard the steps getting closer and louder, closer and louder, and stopped. Hook, line, and sink; she had him. She wanted to smile, but needed to act as though she were clueless that Danny was there watching her. Susie pretended to be checking herself out; fluffed her hair, turned sideways to measure her breasts, all the while making sure that Danny still had a clear view of her. It was time.

Susie dropped her panties to the floor and stepped out of them, never taking her eyes off the mirror and keeping a vigilant view of her brother. Her cunny was hairless and her slit was wet. She moved her hands back and down to her butt. "Time to really give him a show." She said to herself. Susie bent slightly over and spread her cheeks revealing a blue ring poking out from her asshole. She wrapped one finger through it and slowing began pulling it out.

Movement in the door way caught her eye. Susie focused her eye sight while continuously pulling the dildo out of her ass little by little. "He's jerking off!" She finally had it plop out leaving behind a nickel sized gab, "Mmm." Susie brought it up to her lips as she stood back up and gave it a sultry kiss then sucked it. "You enjoy that little peep show?"

Danny didn't say anything. He was stunned and speechless. His big sister was in front of him naked and just pulled some blue plastic toy out of her butt and kissed it! And she knew he was watching! "Uhh" Danny's throat went dry.

Susie let out a laugh and spun around. She walked towards him swaying her hips in a manner no average 13 year old should be able to do. Danny still couldn't speak. The sight of his sister was so sexy. Susie grabbed his shirt and pulled him close. "Well, lets see if we can loosen that tongue of yours shall we?" She leaned in and planted her lips onto her brother and stuck her tongue into his mouth. What Susie didn't know was that Danny and their mother have kissed plenty of times.

Danny met her touch with similar ferocity. Susie was surprised. She didn't expect Danny to be capable of reacting so strongly. Their tongues swam and clashed against each other. Danny grabbed her waist and pulled her closer to him. Susie responded by wrapping her arms around his neck. When they broke, a strand of spit hung between their lips. It snapped down the middle. Susie's small chest was heaving. "Wow Danny, you're a natural!"

"Practice makes perfect." It never even occurred to Danny that one, this might be considered cheating on his mother, and two, that he might have just given away the fact that he was having a relationship.

"Practice? Has my little brother been making out with other girls?" Susie said smiling.

"Uh-oh." Danny needed to think quickly. He promised their mother he wouldn't let Susie know about their little sex scandal. "but Mom didn't know about this! I can't wait to tell her! Would she change her mind if she knew? If she gets mad, she might be angry enough to hold sex!" Danny needed to change subjects and keep his secret just in case. "Well I kinda think the more interesting question is what's happening here? You know, you, me, and that uh blue toy you just pulled out of your bum." He slid his hand down her back and squeezed her ass.

"Oh you liked that did you?" Danny nodded in reply. "Would you like to see it again?" Danny's mouth parted with that offer. "Hmhm. I thought so."

It would have to wait. They both heard their mother call for them from downstairs. "Danny, Susie, could you two come down here for a minute?"

"Damn it." Danny said under his breath.

Susie laughed. "Calm down little brother." She traced her finger down his torso and tucked her hand in his pants. When she found what she was looking for, she smiled. "They'll be another time." She then called out, "We'll be right down!"

Susie slipped her sundress back on, when Danny spoke. "Hey Susie?"

"Yeah?"

"Could you put that toy back inside you? Thinking how you had it in all this time makes me so...I don't know the word that describes it."

"It turns you on." Susie answered.

"Yeah and if I knew you were wearing now."

Susie laughed. "My little brother is quit the man now. I'll wear it, for you." She said with a smile. Susie picked up the dildo and lubed it with some spit. She lifted her dress, spread her legs, and leaned in a bit. She brought the toy up to her butt hole and gently eased it in. Danny watched as the blue plug disappeared. Susie stood straight and adjusted a little bit. "There we go. Now we better hurry downstairs or Mom will expect something." She walked past Danny who leered at her ass knowing what was between those two beautiful cheeks.

"Wait." Danny said. Susie stopped to look at him. "Are we going to have sex?"

"Tonight?" Susie asked.

"Yeah, I was hoping."

"You don't like to waste any time do you Danny? Not tonight. I want to spend some mother daughter time with Mom. I haven't seen her in such a long time." That was partially true. Susie did want to spend some time with her Mom, but she also wanted to begin the process of seducing her. "Now please, lets go downstairs."
