Yao Le’er knew what French kissing was all about, and her mind was already buzzing just listening to it.

　　The sister-in-law is now in a state of being “trained” and is extremely ashamed. This real first kiss should have been led and guided by the experienced brother-in-law, but now she is the one taking the initiative. It is really embarrassing, but it is also a unique experience.

　　Xu Bin’s lips were open, and Yao Le’er, feeling shy, still boldly stuck out her tender little tongue and clumsily found her brother-in-law’s tongue and gently licked it.

　　”Ding… The mission 1 of ‘Baby-faced, Big-breasted Sister-in-law’ is complete. You have fulfilled the additional condition and will receive two chances to randomly draw blind boxes.”

　　”Draw now?”

　　”no……”

　　At this point, Xu Bin had no intention of interrupting. After planning for so long, it was time to reap the rewards. Once the mission was confirmed, the affectionate brother-in-law would transform into a lecherous beast.

　　Yao Le’er was still feeling ashamed and annoyed that her brother-in-law was so mean. He had to tease her like this during their first kiss. When he kissed her, his tongue was as stiff as a log and wouldn’t move. How could he do that?

　　However, as soon as this thought crossed his mind, Xu Bin’s hands, which had been touching her buttocks, exerted force and suddenly grabbed her elastic and soft buttocks through her pants and began to knead them.

　　A tingling, electric sensation shot through Yao Le’er, causing her to let out a soft moan and stiffen. At that moment, Xu Bin, who had been behaving himself, also became more primal, kneading his sister-in-law’s buttocks and sucking on her frightened little tongue, licking and tasting it.

　　There seemed to be a faint, sweet milky fragrance. The taste made Xu Bin’s head spin. After suppressing his feelings for so long, he could finally enjoy his sister-in-law’s first kiss.

　　Yao Le’er felt weak and powerless from the kisses, and her clumsy little tongue responded, excited and absorbed, hugging Xu Bin even tighter.

　　The two were passionately kissing on the sofa. As their tongues intertwined, the woman’s instincts were awakened. No matter how clumsy she was, the most wonderful thing was that she received a passionate response.

　　”Brother-in-law…”

　　Yao Le’er was already completely captivated by the kisses, and couldn’t help but murmur.

　　It was the first time her tender buttocks had been so roughly grasped and played with. Even through her pants, the feeling of weak submission was particularly intense. At that moment, she sensed that her brother-in-law was very excited.

　　The fact that their genitals were pressed together through their clothes made her restless. An itch that felt like ants crawling all over her body overwhelmed her. Just then, Xu Bin grabbed her buttocks and began to roughly rub her soft area against his penis.

　　The pleasure brought by this rubbing was incredibly intense. Yao Le’er let out a soft moan and tried to struggle but was powerless. Lost in the passion of being kissed, she could only let her brother-in-law do as he pleased.

　　A wave of pleasure surged over her, and even though she was wearing clothes, the rubbing became more and more intense. Yao Le’er’s whole body was hot, her face was covered in fragrant sweat, and her little body was restless.

　　”Waaah…”

　　Finally, Yao Le’er couldn’t control herself anymore. An almost suffocating feeling spread and her whole body stiffened. The impact of the mini-orgasm was so intense.

　　Seeing that she had almost lost consciousness, Xu Bin suppressed his impulse and held his sister-in-law in his arms, gently stroking her back, kissing her face from time to time, and licking the sweat from her face.

　　His movements were unusually gentle, showing the utmost care and concern; he restrained himself from doing anything that would have been more excessive when the emotions were running high.

　　Yao Le’er nestled comfortably in her brother-in-law’s arms, closing her eyes and panting heavily. She knew clearly that this must be the feeling of an orgasm.

　　My sister-in-law had masturbated before, a process filled with curiosity and unavoidable moments, only the sensation wasn’t as intense as this. It even made her uncontrollably yearn for how intense real sex would be.

　　After resting for a while, Yao Le’er’s breathing gradually calmed down.

　　However, she remained nestled in Xu Bin’s arms, not opening her eyes because she was too ashamed. Now that she had calmed down, she was unsure how to face him.

　　My brother-in-law trained me to be so proactive during my first kiss, and he even brought me to orgasm. He must know that.

　　The sister-in-law, just beginning to experience romantic feelings, was filled with sweetness. She wasn’t some clueless idiot; all the nonsense she heard from her mother and others outside seemed to share a common theme.

　　Men are all incredibly rude beasts; once they get hard, they’re no different from wild animals. But now, my brother-in-law is gently touching and kissing my face without making any excessive moves.

　　But when her brother-in-law was so gentle and caring after her orgasm, she was almost fainting. If he had done something inappropriate then, she probably wouldn’t have been able to resist and would have let him do whatever he wanted.

　　”Baby, does it feel good?”

　　Xu Bin knew she had rested well, so he kissed her cheek and asked her gently.

　　”kindness……”

　　With a shy yet affirmative answer, Yao Le’er felt quite embarrassed, but her sweet and lazy voice couldn’t hide her joy.

　　Her arms were still wrapped tightly around Xu Bin’s neck, her small body twitching occasionally. The wonderful feeling of a small climax during their first kiss, without any excessive actions, was a beautiful memory for her.

　　”My darling Le’er looks so beautiful right now!”

　　Xu Bin lifted her chin again and kissed her under her shy and dreamy gaze, continuing to savor his sister-in-law’s incredibly sweet little mouth, kissing her until her bones felt soft and her whole body was powerless.

　　She collapsed into Xu Bin’s arms once more, panting weakly, and unconsciously licked her lips, saying, “Brother-in-law… it’s not what I thought.”

　　”What’s different?”

　　Xu Bin gently stroked her back, afraid that if he touched her shapely buttocks again, he would lose control.

　　Now we’ve at least figured out one pattern: the system’s tasks are always done step by step. Even if there’s an opportunity to go further now, we have to hold back to avoid more trouble later.

　　”Kissing, I used to think there was nothing exciting about it. It was disgusting to see two pieces of flesh touching each other with saliva in between…”

　　Yao Le’er kept her eyes closed in embarrassment, then quickly opened them slightly to look at Xu Bin, saying somewhat shyly:

　　”And my brother-in-law… I thought you’d take advantage of me and undress me or something, but I never expected him to be so gentle…”

　　…If it weren’t for the system task, you probably wouldn’t be a virgin now.

　　Of course, Xu Bin still maintained a tender and affectionate demeanor, taking her small hand in front of him and kissing it, saying gently, “Why are you surprised? In your brother-in-law’s eyes, you are a treasure. Even if you refuse insincerely, your brother-in-law will not force you as long as you are unwilling.”

　　”Brother-in-law, why are you my brother-in-law? It would be so much better if you weren’t my second sister’s husband.”

　　Yao Le’er was also overcome with emotion. Her small hands trembled as she touched Xu Bin’s face, and she said with some pain, “Even if you were a married woman I didn’t know, Le’er would still be willing to be your mistress and be your sugar daddy…”

　　”Le’er, you’re not thinking like that. You’re your brother-in-law’s darling.”

　　Xu Bin hugged her tightly and gently stroked her back, saying, “From the moment I saw those messages, I only felt worried and never had any improper thoughts. I’m willing to be good to you because you’re my precious darling, not because I want to spend money on you or defile you.”

　　”Ding… Sister-in-law Yao Le’er’s intimacy level is 75% (average level for a normal married couple; other foreplay before intercourse is acceptable…)”

　　Xu Bin was taken aback, not expecting that correct language could be so powerful.

　　”Brother-in-law, I know it’s always been me who’s petty, always scolding you and calling you a pervert.”

　　Yao Le’er also said emotionally, “I don’t actually dislike you, I’m just shy…”

　　Their relationship was heating up further when Xu Bin’s phone suddenly rang.
