Your Sister was already awake

You woke up in bliss. You looked down and saw Sarah casually sucking your hard dick. You suspected that she had been at it for a while. It took a minute for her to realize you were awake. When she did, She pulled off, her hand replacing her mouth.

"Morning Kyle!" She said with that cute innocence

"Morning Sarah."

"You are hard to wake up."

"And hard. How long have you been doing this?"

"Don't know. I enjoy sucking your dick so much that I lost track of time. Maybe fifteen minutes? But now that you're awake, let me finish, please?" She was almost begging.

"Go ahead then."

Her beautiful smile widened as she swallowed your dick. Earlier she had been sucking almost absentmindedly. I wouldn't have been surprised if she was on her phone while sucking, though her phone was over on my desk. Now, she put her full effort into it.

Within moments, she was slobbering over your dick and deepthroating it. You just lay there and let her do what she wanted. Despite her inexperience, she was very good. You soon felt yourself at the edge. You edge her off and have you kneel at the foot of the bed. You stand over her and jackoff until her explode over her face.

She tries to lick it off, but you stop her.

"I want you to go to breakfast like that."

Her face turned bright red at the thought, but as you went to your closest to get another pair of underwear, you see how wet the thought had made her.

You think to yourself, "Looks like she likes being exposed. That'll be fun."

You pull up the boxer briefs before you think to yourself.

"Hey Sarah?"

She looked up from her still mostly unpacked things, "Yeah?"

"The family only wore underwear inside the house because you were shy. Do you still want us to?"

"At this point, I don't mind, but I think I'd prefer you to wear some."

"Why only me?"

"I'm fine with wearing your cum to be seen by the family, the idea makes me surprisingly horny, but I would prefer not to jump on you and do something in front of them."

"Ok then."

She turns back to her stuff. You sneak up behind her and hugged her, cupping a tit in each hand. She yelped in surprise.

"Sarah, I am going to ask you a lot of things. Ask you to do a lot of things. I'm trying to identify the limits, so if something I ever ask you, or do, makes you uncomfortable, just tell me."

"Kyle, I meant what I said last night. I am yours. It'll take me some time, so I appreciate this, but I want to be your slutty sister. I want you to be my master."

"I'd kiss you right now if you weren't covered."

"Oh, does your command have unintended consequences?" She jokingly teased.

You chuckle and unwrap your arms from her, spanking her tight ass before walking away.

Lora called down from the kitchen that breakfast was ready.

The two of you walked down. Sarah had opted for a bra instead of her usual oversized shirt. You assumed she did so; so that she wouldn't smear the cum that still plastered her face.

You noticed that the amount of cum was much larger than normal. You also seemed to be able to cum more often. You just left it as 'That god did something'.

The kitchen was much like it was yesterday. Your Father and Mother were sitting at the head of the table working. Amber was cooking and Lora was setting the table. You and Sarah sat down and it wasn't until the meal was being served that Amber noticed Sarah's face.

"Oh my!" That caught everyone's attention.

They all then noticed and suddenly everyone was talking. Amidst all the chatter you heard that everyone was happy. All the chatter stopped when your Mother stood up, walked over to Sarah and kissed her on the lips. It most definitely wasn't a motherly kiss. When she released your sister, her tongue licked up some of the cum.

No one moved until your Mother sat back down. Then Amber kissed Sarah, licking up more of the cum before she sat down. Lora followed suit and licked up the remaining amount.

You and Sarah were frozen in shock, but she was bright red and she definitely wanted the kisses to last longer.

Your father burst out in laughter, "Congrats you two!"

The rest of them just had contented smirks.

"Ummm, what was that?"

"Oh, I thought you knew. Its an old tradition from my generation. When a new girl is added to the Harem, the man covers her face in his cum and then the other women will kiss her and lick off some of the cum as a way of welcoming the new girl to the sisterhood."

"But isn't Sarah the first girl in my Harem?"

Your mother spoke up, "That is a bit of a grey period. Your Father has transferred us from his Harem, into yours. But that is very rarely done. So, Sarah is the first girl you took into your Harem, but we are still part of your Harem."

"What she means, Sarah is technically the First Harem Girl because you brought her in yourself. With your own efforts." Lora said

"You say First Harem Girl like its a title." You notice.

Amber spoke up, "The official title is First Wife, but you two aren't married yet. This is more amongst the women."

"Meaning us men have no place to interfere." Your Father smirked.

"No, the man may change anything he wants, but its highly advised to not change the Wife Order of the Harem. The Order is a Hierarchy among the women. Just look at your Mother. She is the First Wife. She holds the most power after your Father. Then its me, then Lora. You can also notice the order with the jobs we do."

"So Lora takes care of the house because she is the lowest Wife?" That sounded almost tyrannical.

"Oh don't get it wrong Kyle," Lora spoke up, "I do the housework because I enjoy it. Amber cooks because she enjoys it. She organizes your Father's files and patients because she is good at it."

"The order just happens follow their desires. I have never cared for the 'First Wife, Second Wife, etc.'. They are all my Wives. But, there are Harems out there that are very strict in the order, and there are some that treat the 'lower' Wives as little more than servants."

"Father, Mother said that you transferred them into my Harem. Is that true?"

"Yes. I have a friend who is a lawyer, he helped me with the process. Now, legally, they wont be in your Harem until I die, but I'd like you to act like they are part of you Harem now so that when I go, its as smooth a transition as it can be."

"Wait, why are you acting like you are going to die soon?" Sarah spoke up.

That caused the same conversation from yesterday. By the end of it, Sarah was in your Father's lap hugging him tightly while she cried. Your Mother hugged her from behind. When the alarm to leave for work went off. Amber turned it off, and you helped Lora clean up.

Eventually, they had to separate. Sarah launched herself into your arms, and shoved her face into your chest, still quietly sobbing. Your parents got dressed and left. A few minutes passed before you pulled Sarah away and look in her eyes.

"Why don't you skip school today? We can go to the mall or the park?"

"That would be nice." She mumbled.

"Alright, go get dressed."

She was slow to walk upstairs. While she dressed, you planned events to help distract her. When you finished, you went up to get dressed. She was just finishing up, but you still admired her tight ass and full bouncy tits. You both finished getting dressed and got in the car.
