"Is everything okay?" Sarah asked her nephew Owen.

"Yeah, Auntie... why wouldn't it be?" He answered as he continued eating his breakfast. "By the way, thank you so much for letting me and Mommy stay for the summer. It's so nice here."

Jane, Sarah's maid, walked by to refill Owen's orange juice. Owen looked at her, "Thank you, Jane." 

"Hmmm, Jane please leave us alone for a moment." Sarah requested. 

"Of course ma'am." Jane nodded and left.

Owen suddenly looked more serious.  "I don't have a girl in uniform walking around my home taking care of my needs. It's nice to have a girl in uniform taking care of my needs."  His voice got slower and more confident at the end.

"It's nice to have a girl in uniform taking care of your needs." Sarah repeated in a dull monotone.

"You love to make me happy." 

"I love to make you happy."

Owen gave out a little giggle. "Aunt Sarah, what did you want to tell me? I think I interrupted you."

"Yes... well, I want you to be happy." Sarah paused for a second, trying to figure out how to word this. "Well... Let me start at the beginning. I thought something was wrong with my sister right after you arrived. I asked Jane to set up two rooms for you and your mother."

Owen interrupted. "Mommy. Her name is Mommy. It's not my mother or your sister or Michelle.  It's Mommy."

Sarah tried to regain her train of thought. "Her name is Mommy. Okay yeah, so we set up two rooms but your Mommy insisted that you two sleep in the same room. I didn't say anything because she is your mother... I mean Mommy. But you are eighteen and I think you should have your own room. Then she ordered Jane to stay out and insisted that she be the one to clean your room. I felt that she was isolating you. But then.... last night happened. I heard weird noises coming from your room. I opened your door and I saw your Mommy riding your cock while wearing a sexy maid outfit." Sarah paused again. "Is Mommy forcing you to do this? You can tell me. How long has this been going on? It's not okay for her to do this to you."

"Oh Auntie, calm down. I like it. It feels so good." Owen said innocently. "Mommy thinks it's very important to make me happy."

"Of course, I love making you happy as well. But incest is not okay." Sarah tried to debate.

"If Mommy thinks it's okay, then it's okay."

"Owen, how long has this been going on?" Sarah tried to get control of the conversation.

"Since my eighteen birthday. I was playing with one of my birthday gifts and then Mommy told me about her new philosophy."

"Okay...." Sarah tried to process all of this.

"If Mommy's parenting techniques make you uncomfortable, then you should just talk to her." Owen recommended.

"No, I'm calling the police. I need to make sure everything is okay. I know that I'm doing this for your own good."

"No!" Until now, Owen had been incredibly calm, like everything was completely normal. Suddenly, as he spoke this word, he became angry. Sarah felt her body and mind freeze.  She couldn't think and couldn't move. "Family stuff stays in the family."

Sarah repeated mindlessly, "Family stuff stays in the family."

Owen insisted. "Family stuff stays in the family."

Sarah echoed again as she became able to think and move. "Family stuff stays in the family."

Owen breathed a sigh of relief. "Talk to your sister.  She loves you. I'm sure you two can figure it out."

Sarah took a deep breath. "Yeah, I don't know what I was thinking. Family stuff stays in the family. But this can't continue, okay?"

Owen smiled. "I will do anything Mommy tells me to do."

Michelle had changed so much in the last year. Sarah sat across from her sister trying to come up with the right words, but how could she? They were sitting on the bed where Sarah had seen her sister fucking her son. Michelle was wearing a sexy maid outfit. Since the last time Sarah had seen Michelle, she had gotten breast implants. They looked like they wanted to spill out of her outfit. "Do you have to wear that?" Sarah asked. "I mean, it's not appropriate."

Michelle smiled. "Yes, I do. Mommy thinks that it makes my Good Boy feel better. He loves it. Mommy is always right."

Sarah tried to talk but instead she startled a little, finally managing to get out her words. "Yeah, Mommy is always right but... well Owen..."

Michelle interrupted. "His name is Good Boy. You will call him Good boy. He is my good boy. You are his Aunt so he is your Good Boy as well."

Sarah felt like she was about to shatter. "His name is Good Boy. I will call him Good Boy. Sorry, Michelle... I mean Mommy... Ummm... Well, Good Boy is not here is he?  So, do you need to wear that now?"

"He isn't here right now, but he could come in any second. Good Boy sometimes misses his Mommy and if he comes in, then I want him to see me in my uniform right away." Michelle explained.

Sarah took a deep breath. "Okay... I need to talk to you about something. How do I say this? I saw you fucking your son. It's wrong and it can't continue."

"Wrong? Didn't you hear me and my Good Boy moaning with pleasure? We were enjoying it." Michelle said, confused.

"Well, incest is wrong.  It doesn't matter how much you enjoy it. You are taking advantage of him.  He doesn't know any better." Sarah said in disbelief. 

Michelle's voice transformed into a much more serious tone. "Sarah, It's wrong for Aunties to criticize Mommy's parenting style."

"Is wrong for me to criticize your parenting style," Sarah said, suddenly embarrassed. 

"It's up to me to decide what my Good Boy and I do together." Sarah continued.

"It's up to you to decide what you and your Good Boy do together."

"Aunties have a responsibility to help Mommies take care of their kids."

"Aunties have a responsibility to help Mommies take care of their kids."

"Aunties can't overrule Mommy. He is Mommy's Good Boy after all."

"Aunties can't overrule Mommy. He is Mommy's Good Boy after all."

"Aunties love to make their Good Boy nephews happy."

"Aunties love to make their Good Boy nephews happy."

"Aunties must do anything Mommy tells them to do if it makes their Good Boy nephews happy."

"Aunties must do anything Mommy tells them to do it it makes their Good Boy nephews happy."

"I'm happy you understand now," Michelle said, much more relaxed.

"But fucking... I mean he is your Good Boy so you can do anything want. But why fucking?" Sarah asked. She was now just curious, not concerned.

"You saw us. Be honest. You got turned on by watching me and my good boy fucking."

Sarah took a second to respond. "Yes, I got turned on by watching you two fucking... but."

Michelle spread her legs.  Her maid skirt rode up enough to reveal that she wasn't wearing any panties. Her hands dropped to her pussy and she started to tease herself and give out tiny moans.  "It's so hot to remember."

"It's so hot to remember." Sarah felt herself getting flustered. "But we are... you can't..."

"It's perfectly normal for sisters to masturbate together.  It feels good.  There is no judgment between us."

"You are always right. It's perfectly normal, there is no judgment, and it would feel so good." Sarah quickly pulled off her leggings and panties.

Michelle giggled. "Now you see one of the benefits of my uniform."

"Hehehe... yes I do." Sarah spread her legs, just like her sister, and started touching her own pussy. "Oh my god... I think I was so shocked when I saw you fucking that I didn't realize how cute he looked as you rode him... and you, with your boobs bouncing in that sexy maid outfit. Oh my god. You are right, you made him feel so good."

"Is that all you saw?" Michelle asked, her smile full of joy.

"Yeah, I got scared and left," Sarah said, trying to keep her moans in.

"Oh you missed so much... my Good Boy put me on all fours and just started to fuck my ass over and over again. Oh, he loves doing that so much."

"Oh fuck that is so hot...." Sarah started fingering herself more enthusiastically. Both of the women just sat facing each other and touching themselves for a couple of minutes.  The only sounds were their moans. After a bit, they both slowed down a little. "This is so wonderful. I'm so happy you figured this out. Both of you seem so much happier. Where did you hear about this?"

Michelle looked excited. "I didn't, I came up with it all by myself."

"Really?"

"Yeah, it was the night of his 18th birthday. After the party, he was reading this mind control book that he had asked me to get for him. We were just talking and then I suddenly had this realization. We would be so much happier if we were closer. Good boys need to release their sexual urges. My good boy probably thinks that his Mommy is so hot. Mommy definitely thinks that her good boy is incredibly hot. It's normal for older women to find eighteen-year-olds hot."

Sarah leaned back into the bed and started touching herself faster "It's normal for older women to find eighteen-year-olds hot."

Michelle continued. "Incest is just a social taboo. If fucking made us happy, why not? So I put my hand on his leg and, before we knew it ,I had his cock in my pussy. Oh, he felt so incredible. Nothing like it."

"I'm so happy for both of you."

"I'm so lucky. I wasn't going to make a move but then something came over me." Michelle sounded thankful.

"Did you ever wonder if maybe he used mind control to make you think that?" Sarah said, concern returning to her voice.  She couldn't stop touching herself, however.

"Mind control isn't real. Mommy is in control. Good boys can never trick their Mommies."

"Yeah, silly me. Kids always think they can get one over their parents, but we are just so much smarter than they are. Mommies are always in control. Mind control isn't even real."

"I'm happy you understood so quickly. I struggled with it at first, but it made sense after my good boy explained it to me." Michelle said. "Well anyways, can I go back to the birthday story?"

Sarah pulled her shirt and bra off so that she could start teasing her nipples with one hand. "Yes, please continue. Your story makes me feel so hot."

"I'm happy you are enjoying it." Michelle giggled as she saw her sister feeling so much pleasure. "Well, after my good boy filled my pussy with his cum, I kept thinking. What else can I do to make my good boy happy? I realized that I should serve him whenever and however he wants and that I should dress appropriately."

"That's what the maid outfit is for!  I'm so dumb. You are so smart. It suits Mommy so well."

"I know, I look so cute. It also makes it so my Good Boy can fuck me any time he wants."

"That sounds amazing."

"It is. I also thought that maybe I should do things to make my body look and feel better for my Good Boy.  So I started exercising and losing weight, plus I got breast implants." Michelle said with pride.

"You are such a good Mommy." Sarah congratulated her.

The two women heard a knock at the door.  Without waiting for a response, the door opened and Owen walked in. "Is everything okay? You two have been in here for a while." 

Michelle responded immediately. "Oh it's going great. It's just two sisters touching themselves together. Take off your pants and come join us." Michelle spread her legs.

Owen let his pants drop, revealing that he was wearing no underwear. His cock was hard and he started stroking himself immediately. He walked forward until he met his mother with a passionate kiss. Sarah watched, astonished by how natural and comfortable they looked. Owen kissed his way down to her mother's boobs and then his cock slid into her pussy.  He started slowly fucking his mother's pussy.

Sarah bit her lip as she saw her nephew fuck her sister. "Can I help? Can he fuck me too? I can make him happy too. I want him to make me happy too."

Owen kept fucking his mother with his lips happily sucking one of her nipples.  After a moment, he looked with a smile up. "Can I mommy?"

Michelle giggled. "Keep sucking dear.  I will take care of this." Owen smiled and continued sucking. Michelle turned her head to her sister, who was trying to contain her moans. "You see dear, my good boy is such a jealous boy. So if you want me to let him fuck you, you have to promise that you will never fuck anyone else."

Sarah didn't skip a beat. "I promise that I will never fuck anyone else."

"Your body belongs to my good boy." 

"My body belongs to your good boy." Sarah said, unable to look away from her nephew. She was sure that he had started to moan more in response to her proclamations.

Michelle looked down. "Good Boy, I think you should play with your Auntie for a bit."

Owen looked up and smiled at Sarah. As he got off his mother, Sarah scooted on the edge of the bed and spread her legs.

Michelle smiled. "Your Auntie is wet and ready for you."

Owen got up and moved to right in front of his Aunt.  His mother stood up and got behind him. Her hands reached around him and caressed his chest. Sarah watched as her sister whispered in Owen's ear. Owen giggled a little before he pushed his hard cock slowly go into his Aunt. Michelle was right. It felt so good to make her good boy happy.

Sarah came downstairs in her slutty maid outfit while trying to figure out what was taking her sister so long. "Michelle, your good boy is getting bored.  I can only distract him with my smaller boobs for so long." Sarah walked into the kitchen. She found her sister whispering into Jane's ear. Jane had vacant eyes and a huge smile. "Does she like the idea?" Sarah asked.

Michelle smiled. "I mean, how could she say no?"

Jane nodded. "I have loved servicing Owen for the last couple of days. I didn't realize it until right now, but it's the happiest I have ever been. I will do anything you tell me to, Michelle. I want to help you make Owen happy."

Michelle giggled "Call him Good Boy."

Jane corrected herself,  "I will call him Good Boy.  I will do anything to make your good boy happy." Jane looked thoughtful moment. "Do you think your good boy would like to take my anal virginity?" She asked excitedly.

"Oh yes, he would." Michelle confirmed. 

"Great!" Jane started to hurry to Owen's room. 

"Wait!" Michelle stopped her and then started unbuttoning Jane's conservative maid uniform. "Our Good Boy deserves to have us always wear outfits designed to make him happy.  Yours covers too much. Until we get you a proper, sexy uniform, you will wear nothing but panties around the house."

Jane smiled and repeated her new truth. When she finished stripping, Michelle smacked her ass to send her on her way.

Michelle and Sarah followed Jane, watching as she went into Owen's room. They both sat on the floor outside the door with legs spread and began touching themselves. They listened to Jane moan as Owen fucked her ass. Michelle had to be honest with herself.  This was boring her a little bit, but she wanted to be ready just in case Owen needed them. She had to be wet and ready at all times for her good boy.
