CHAPTER 43: DON’T BE UNFAITHFUL

Leah was in a daze for a moment, and it was Avery who was talking throughout the whole speech.

The chat history looked particularly aloof, until the very end when Luis typed a few words: Thank you, Leah is in school, I hope you can take good care of her. If there is anything that is difficult to talk about, please let me know. If you need money and it is inconvenient, you can tell me.

"Brother in law, so serious..."

"Stinky brother in law, ahhh, I am jealous as hell."

"Bunny said you were a taciturn pervert before, why do you care about her so much? Brother in law, please say a few more words, I want to chat with you."

The reply Leah saw was extremely serious: "Sorry, it is time to go to bed now."

"Brother in law, why are you sleeping? Can not you just chat with me properly?"

"You must have ulterior motives towards your sister in law. Do not act stupid here."

"Stinky brother in law, do not lie to me. Which brother in law not only spends money on his sister in law but is also so considerate? Do not think I can not see it."

After she repeatedly questioned him, Luis suddenly asked, "How much to take your virginity?"

There was no reply from Avery instantly. When Leah saw this, she had a vague idea that her brother in law asked this question because he was annoyed.

The main reason is that the little bitch said a lot and was annoying, so it is not excessive at all to suddenly say this. To say that it was a monetary transaction actually has a bit of ambiguity that is hard to understand.

The next reply, one sentence, was enough to drive her crazy:

"Brother in law, I do not want to be a prostitute... Just promise to treat me as well as you treat Bunny."

Leah squinted her lips, gritted her teeth and said, "This little bitch dared to seduce my brother in law. I will beat her to death later."

Luis smiled warmly and said, "Do not be angry, I was just joking. There is no way we would really have an affair after just one meeting."

"That is not necessarily true. Avery has such a good impression of you."

The more Leah thought about it, the more worried she became.

The internal conflict among their best friends is not a good thing, at least it does not benefit Luis at all, and it will easily make him unpopular with everyone.

Luis quickly shifted the focus and said in a slightly dissatisfied tone, "Baby, I think there is something more important. Do you have such a bad impression of your brother in law?"

Leah’s pretty face suddenly turned red, and she lowered her head embarrassedly. She also put Luis’s mobile phone aside, and her little hands were restless.

"Brother in law, that was my misunderstanding. Can you just treat it as nonsense?"

The more the sister in law thought about it, the more unreasonable she became. She felt so guilty that she even spoke in a whisper.

Worrying about gains and losses, giving sweet treats and a sense of crisis at times, the naive sister in law had no idea that the devil brother in law was enjoying the pleasure of playing with her psychological ups and downs.

Luis looked at his embarrassed sister in law, whose face was as red as a peach in March. She looked pitiful and well behaved, and was as frightened as a child who had done something wrong.

"Baby, come here and give your brother in law a hug!"

Luis put out his cigarette and opened his arms towards her. With the experience just now, Leah was not shy this time. With a blushing face, she sat astride her brother in law and rested her little head on his shoulder.

This time, the posture was chosen by her, just like the posture of an old tree with twisted roots, she spread her legs and sat on the man’s penis.

The hard cock jumped and hit her through her pants, making her whole body numb, as if she had been electrocuted. She felt embarrassed but did not move.

The genitals were in intimate contact through the cloth. Her weight was all on Luis’s body as she lay limply. The pair of plump breasts squeezed him even harder. Luis was so comfortable that he immediately hugged her back.

His hands gently stroked her lower back, enjoying the beauty of holding her soft and warm body in his arms, and the feeling of her chest rising and falling with every breath.

"Brother in law, please do not let my second sister down."

Leah suddenly spoke, murmuring softly, "Brother in law, Avery might be joking. You are not allowed to really miss her."

"Baby, are you jealous?"

Luis asked teasingly.

Leah remained silent, and Luis continued to tease her, "Baby, do not change the subject. You have said so many bad things about your brother in law. How do you think your brother in law should punish you?"

"I have given you a hug."

Leah blushed and said, "If my second sister sees this, I will be dead."

"Baby, if you do not punish me, you have to compensate your brother in law."

Luis blew hot air into her ear and said seductively, "Brother in law is actually very tempted. Avery is beautiful and has big breasts. If it is paid dating, it is not bad. And she is your classmate, which makes me feel more at ease."

"Hate it, no!"

Leah got angry when she heard this. She sat up straight and looked at Luis straight in the face. She punched Luis’s chest with her pink fist and threatened him in a soft and coquettish tone:

"If you dare to sleep with Avery, I will definitely tell my second sister."

Luis smiled as he looked into her big, watery eyes. His hands were still holding her lower back, and he controlled the urge to touch her small, perky buttocks. He said jokingly, "Your second sister will not be angry."

"You are talking nonsense!"

Leah naturally did not believe it, and snorted proudly, "Second sister is honest, but that does not mean she does not have a temper."

Looking at her proud and cute little appearance, Luis burst out laughing and said, "Then wait until I hook up with Avery, then you will know if you try it."

This statement was so confident that it sounded like a joke and it was hard to tell whether it was true or not.

Leah bit her lower lip and said fiercely, "No, brother in law is not allowed to be unfaithful."

Luis hugged her tightly again, greedily smelling the milky fragrance on his sister in law’s body, and teased her, "Do not be unfaithful. You can only be good to my baby Leah, right?"

"Except for my second sister... I can only be nice to them."

Leah said shyly and softly.

"Then what is the reward for being obedient, brother in law?"

Luis’s fingers were exploring the area behind her waist, and he was just one step away from touching her plump and perky little buttocks.

"Stinky brother in law, what reward do you want?"

Leah asked softly, her slightly nervous and shy look making people salivate.

She is not an ignorant child anymore. She has been listening to her second sister’s satisfied moans every day these days. Naturally, she knows a lot of secrets between men and women. She certainly does not think that the reward her brother in law wants is something childish.

At this point, Luis could not help but lick her red ear and said, "Brother in law wants to kiss Leah, okay?"

"Kiss, kiss on the cheek?"

Leah asked nervously.

Luis looked at her with a half smile on his face, shook his head decisively, and looked greedily at her rosy and cute cherry lips.

Leah hesitated shyly and said guiltily, "But, but I am your wife’s sister, your sister in law. How can I do this? If my second sister finds out, I will be dead."

"Just do not let her know!"

Luis looked at her lovingly and said softly, "But the one I am holding now is my baby Leah."

Leah did not say anything else and lowered her head silently. After waiting for a long time and seeing that her brother in law did not make any moves, and his hand on her lower back was very polite, she said tremblingly: "Then, kiss me."

After saying that, she shyly closed her eyes, and was so nervous that she held her breath. But her brother in law did not move for a long time. Leah opened her eyes in confusion, quite puzzled.

The system’s tasks were clearly stated. If you kissed her, you would get the normal reward. If she took the initiative to kiss you, the reward would be doubled.
