My cousin Jiajia with the hypnotic glasses

"Your birthday's coming up soon, right? I've got a gift for you." "A gift? How did you know my birthday?" I asked, puzzled. The other person replied with a smiling emoji, "It's a secret." The person I was chatting with was called K. I met him by chance a month ago in the casual chat section of an 18+ forum. After finding we clicked, we chatted almost every day in the chat section.

I checked my forum ID and didn't reveal my birthday, unless he was a hacker or had an administrator account.

"The package will probably arrive the day after tomorrow. Also, I probably won't be on this forum again, so don't look for me." That was K's last message.

Sure enough, a package arrived as promised. I was really surprised. K knew my name and address, but the sender information was blank. Logically, this was impossible; the courier company wouldn't deliver something without the sender's information.

Since I couldn't figure it out, I ignored these questions for now and carefully opened the package.

Inside was a beautifully crafted box. Opening the lid, a pair of silver-framed glasses lay quietly inside.

"Glasses?" I had indeed told him I was nearsighted, but I never expected him to give me these as a gift.

Besides the glasses, there was also a letter and a booklet inside.

I took out the letter first; it was indeed a message from K, telling me to make good use of the glasses to fulfill his dream.

His dream? I was stunned for a moment.

Then I took out the booklet and was immediately attracted by the words on the cover:

"Hypnotic Glasses Operation Manual." "Hypnotic Glasses!" I immediately remembered the idea I had mentioned to K during a chat. We were both loyal players of "Black Rainbow," and the landmark work "Hypnosis Academy" was a topic we talked about enthusiastically. His nickname, K, was even taken from a character in the game.

Of course, what we discussed most was the god-like tool in the game, the "Hypnotic Induction Machine."

"Really?" I couldn't wait to open the manual and carefully read through each page.

An ordinary person would probably grab the glasses instead of flipping through the manual, but having watched countless games and anime where protagonists suffer tragedies because they don't carefully read the instructions, I suppressed my curiosity and carefully reviewed all the important points before picking up the silver glasses.

According to the manual, the lenses of these glasses generate a ray that instantly captivates anyone looking directly at them, putting them into a hypnotic state—a state far beyond what a psychiatrist's hypnosis can achieve. While

most hypnotized individuals retain some self-preservation instincts, those struck by this hypnotic ray will completely obey the hypnotist's commands, even to the point of death, without hesitation or resistance.

The switch controlling this ray is located in the right corner of the stand. However, the ray isn't unlimited; it can be used six times when fully charged. The silver stand itself is a solar energy absorber, taking 24 hours to fully charge from zero, meaning it takes approximately four hours to recharge the energy needed for one use. To prevent accidental activation, there's a safety latch on the left; it can only be used after the latch is released.

I put on my glasses; the prescription was just right. But was this hypnotic ability real? Normally, I wouldn't believe it, but this mysterious K was too amazing. Not only did he know my birthday, but he also knew my name and address. It seemed the best way was to conduct an experiment.

But who should I ask for the experiment?

Just as I was hesitating, the phone rang… “Little brother, are you home?” The voice was… “Sister Jiajia?” “Nothing much, I'll be there soon, just checking if you're home.” “Wow, that's rare! The beautiful lady actually has time to call me. What brings you here?” “Stop being silly. You forgot your birthday is coming up soon. I'll be very busy those few days and might not have time to wish you a happy birthday, so I'm giving you your gift in advance.” “What gift?” I couldn't help but get excited. Sister Jiajia is rich; it must be something good.

“Hehe, I won't tell you.” You'll find out when you get there. "There are four children in our generation: Jiajia, me, Xiaoqin, and Xiaoyi, from oldest to youngest. Besides me, the other three are girls. Jiajia is my aunt's daughter, two years older than me, 25 this year. She's already a well-known fashion designer and owns her own shop.

Jiajia started as a model, so her figure and face are undoubtedly top-tier beauties. Two years ago, she met her current boyfriend, the son of a clothing factory owner. It's said that he fell in love with Jiajia at first sight, and after observing him for a while, Jiajia found him to be a down-to-earth, good man, not the spoiled rich kid type. They started dating and are now at the point of discussing marriage. We met this prospective brother-in-law during the Chinese New Year; he's indeed a good man.

Perfect timing! I was just worrying about who to use for my experiments, and now someone has come knocking on my door. Although I usually seem honest, there's a monster hiding inside me, and I've long harbored wicked desires for my beautiful cousins."

If these hypnotic glasses really work, I'll have to thank K properly.

I tidied up my things, and less than 10 minutes later the doorbell rang.

I opened the door to find a beautifully dressed woman standing there. She had chest-length hair, a classic oval face, and a curvaceous figure—no less stunning than a TV star. Apparently, many talent scouts had tried to recruit her during her university years, but she had refused them all, determined to become a fashion designer.

Even though I was used to seeing her beauty, I couldn't help but feel a flutter in my heart, and the last vestige of my conscience was instantly suppressed by desire.

"What, handsome, aren't you going to invite me in?" Jiajia teased.

"A gift, no gift, no entry." I snapped back to reality, deliberately adopting a childish expression to cleverly conceal my lustful look.

"So eager, huh? Here, take it." Jiajia pulled out a gift from behind her back.

"Hehe, that's more like it." I quickly welcomed Jiajia in, poured her a glass of water, gave her some fruit, and immediately unwrapped the gift. Although it's impolite to unwrap a gift in front of a guest, Jiajia is family, and she knows my personality well

. She looked at me with a smile and wasn't angry at all. Unwrapping the gift, I saw that it was the digital camcorder I'd been wanting for so long. I quickly tested it out; the image quality was clear, and the battery and capacity were extremely powerful. Jiajia had even provided several large-capacity memory cards, enough for seventeen or eighteen hours of recording.

"Satisfied? I knew you liked this camcorder. I'll make it happen for your birthday." Jiajia casually brushed her hair behind her ear, a gesture that was undeniably alluring and sexy. "Huh, you changed your glasses?" Jiajia suddenly noticed that I wasn't wearing my old black-rimmed glasses, but brand new silver ones.

Reminded by Jiajia, I realized I still had something important to do. I'd almost forgotten about the hypnotic glasses because of the camcorder.

"Jiajia, do you think these glasses look good?" While Jiajia was intently staring at the glasses, I quietly pressed the switch. (Of course, I had already deactivated the safety mechanism beforehand.) The glasses seemed to light up briefly, and I almost thought it was my imagination, but I immediately noticed that Jiajia's eyes had changed. Her once bright and lively pupils instantly became unfocused, dilated, and lost their focus.

"Jiajia?" Still a little uneasy, I tried calling her.

"...Yes." A sluggish reply, the same reaction as someone hypnotized in a game. I waved my hand in front of her eyes, but her eyes didn't move. This finally confirmed that Jiajia was indeed hypnotized.

(These really are hypnosis glasses! K, you're amazing.) Taking a deep breath, suppressing my excitement, I recalled fragments of those hypnosis games. First, I needed to set a keyword.

"Sister Jiajia, you feel very comfortable now, very comfortable." "Yes, very... comfortable..." Looking at this beautiful woman who was like a puppet, the dark side of my heart became even more excited.

"When you hear 'the lewd Sister Jiajia,' you will fall into the same state as now." "Yes... the same... state." (Let's try the keyword to see if it works.) "When I count to 3, you will wake up. You will forget what I just hypnotized you, but your subconscious will still clearly carry out my commands." "Yes..." "1... 2... 3!" As I snapped my fingers, Sister Jiajia's eyes instantly regained their clarity. She carefully examined my glasses, as if nothing had happened.

"Hmm, not bad at all. My brother has good taste." But I had no interest in hearing that evaluation and directly activated the keyword: "The Lewd Sister Jiajia." Instantly, Sister Jiajia returned to her hypnotic state.

(Success!) I clenched my fist excitedly. Of course, it wasn't just my fist that was excited; my lower body had been throbbing with rage since earlier. I really wanted to immediately pin this beautiful Sister Jiajia down and ravage her, but playing with a puppet isn't very fun.

MC (mind control) comes in many forms, and my favorite is common sense manipulation, writing lewd and evil things into someone else's mind as common sense. Doing bad things openly is the highest level of sadism.

Next, of course, was to replace Jiajia's common sense with some interesting things. Just thinking about Jiajia's reaction made me feel like my lower body was about to explode. "Bear with it, bear with it, good things should be savored slowly." Just filling Jiajia's memory with these things and replacing ordinary common sense took me quite a bit of time, but I believed my hard work would definitely not be in vain.

"Phew, Jiajia, did you remember everything I just said?" After saying that, I gulped down the water in my cup. After saying so much, plus the feeling of excitement, tension, and stimulation, I was already feeling parched.

"Yes... I remember." Although I only said it once, a person in a hypnotic state would never forget anything. The human brain is indeed a very powerful thing.

"These common sense rules only apply when you are alone with me. When a third person is present, you will still use your old common sense rules. And you will not tell anyone about these things, nor will you write them down, not even your boyfriend or any relatives." Of course, for my safety, I still had to do some precautions.

"Yes... I won't say..." "Good. When I count to 3, you'll wake up, but you'll have to treat everything I just said as common sense. 1...2...3!" Jiajia's eyes cleared again, seemingly no different from before, but I knew that the Jiajia in front of me was now a "woman" I had transformed; yes, her identity as a woman excited me even more than her identity as a sister.

"Speaking of which, it seems like it's been a long time since I greeted you." Of course, this greeting was different from the ordinary one.

Acting on her words was Jiajia's nature. Almost as soon as she finished speaking, she sat on my lap, and before I could react, she kissed me, and it was an extremely passionate and bold French kiss.

Jiajia's nimble and warm tongue gently parted my lips and began to entwine with mine. "Common sense changed, greeting my cousin = French kiss" (The feeling of kissing is indeed very good, no, even better than I imagined.) A unique feminine scent wafted into my nostrils, instantly intoxicating me.

Luckily, my first time was with my experienced cousin. If it had been a novice like me, we probably would both have been at a loss.

My cousin's French kiss was incredibly passionate, almost sucking up all my saliva. Then, her throat moved a few times, as if she had swallowed all of it.

Of course, I wouldn't just sit there and wait to be taken advantage of, so I started my own attack. My palate, gums, and the back of my tongue, guided by my cousin's fragrant tongue, gradually found their rhythm. I gently took her tongue in my mouth and sucked hard.

"Mmm!" Jiajia trembled slightly, but then she became even more intense in our kiss.

After a full five minutes, we both felt a little tired and slowly separated, a glistening line of saliva still connecting our lips.

Jiajia's cheeks were flushed, and her breathing was rapid, but even so, her eyes remained clear, as if the intense French kiss was nothing more than an insignificant thing.

I guessed my face was just as red and hot now, but I didn't show any surprise.

"Sister Jiajia, how's work lately?" I asked, feigning interest. This was crucial for what was to come.

"It's alright, just a bit sore. I guess I'll need to get a massage to relax sometime." Just as I finished speaking, Sister Jiajia's eyes suddenly lit up. "By the way, little brother, why don't you give me a massage?" I pretended to be surprised and said, "But Sister Jiajia, I've never learned how." "It's very simple, I'll teach you." Saying this, Sister Jiajia stood up and took off her coat, revealing only a tight-fitting cotton tank top. Because it clung to her body, I could clearly see the outline of her bra.

My cousin sat back on my lap, but this time with her back to me, her lower body pressed against my erect penis, though she seemed completely unaware.

"Give me your hand." I obediently extended my hand, and Sister Jiajia grabbed the back of my hand and then pressed it against her breasts.

(So big, so soft!) Even through her clothes, I could still feel how alluring Sister Jiajia's almost impossible-to-grasp full breasts were. "Common sense changes, massage = breast kneading." I gently pinched it, and the elasticity and softness it gave was indescribable.

"Yes, like that, knead slowly, wow, not bad, little brother, you have a talent." Sister Jiajia praised while instructing.

"No, many people can do it without a teacher." Kneading a beautiful woman's breasts is something any man is born with, no need to learn.

Sister Jiajia's breasts felt really good, no matter how I kneaded them, I never got tired of it. For a moment, I had a childlike feeling and kneaded Sister Jiajia's breasts into different shapes, which was very fun.

Gradually, Sister Jiajia's breathing became heavier, and her lower body swayed slightly involuntarily. I could even feel a kind of wet liquid on my penis.

"Take off your bra, it will be more effective to massage directly." Sister Jiajia had completely regarded breast kneading as a massage, and even asked me to take off her bra without any hesitation.

Upon hearing the command, my already somewhat erect penis twitched. I had never done anything like unhooking a woman's bra before. Freeing my right hand, I rolled up Jiajia's close-fitting vest. I didn't intend to take off this cotton vest right now.

Jiajia's bra today was a vibrant red, and it was even strapless; it would automatically fall off once the back clasp was unfastened.

Whether it was due to nervousness or because it was my first time unhooking a woman's bra, I couldn't undo even one small clasp.

"So clumsy," Jiajia chuckled softly, seemingly noticing my predicament. She then easily unhooked the red bra.

In an instant, my breasts, which had been restrained, sprang free.

I picked up the red bra that Jiajia had placed aside and held it to my nose, inhaling deeply. A tantalizingly sweet, feminine scent filled my nostrils.

"It smells so good." Jiajia didn't seem to mind my lewd behavior at all. Instead, she happily said, "Since you like it, little brother, I'll give it to you. Now, continue massaging me." (It feels so wonderful even through her clothes; what would it be like to touch her directly?) I couldn't help but swallow hard. My hands tremblingly climbed onto Jiajia's breasts. An indescribable, wonderful feeling spread from my palms—soft and elastic, like jelly or pudding. How could such a wonderful thing exist in the world?

Jiajia's breasts seemed to have a magical power, firmly holding onto my hands, allowing me to caress and knead them incessantly.

My fingers quickly reached her nipples. Perhaps because of the earlier kneading, Jiajia's nipples were already erect. I gently pinched them a few times.

"Mmm..." I seemed to hear Jiajia biting her lip and moaning in my ear. Although Jiajia's mind wasn't fully engaged, her body was very honest, already experiencing that pleasure.

Just then, a pleasant phone rang from Jiajia's bag.

Jiajia casually opened her handbag and took out her phone. I quickly glanced at it and saw the name on the screen was that of my future brother-in-law.

"Honey, aren't you busy? Why are you suddenly calling me?" Jiajia's tone was perfectly normal, showing no sign of discomfort because I was fondling her breasts.

This kind of situation really excited me; it's a common plot in many NTR games, where the heroine is having sex with someone else while talking to her boyfriend, all while suppressing her excitement so no one can hear.

Although the situation wasn't quite that serious, it was still very satisfying.

While Jiajia was talking to her future brother-in-law, I turned Jiajia's body to the side. Before, because her back was turned, I couldn't see it directly, but now it was different. Jiajia's perfect, full breasts were completely exposed before my eyes. Although I hadn't measured them, judging by sight, they were at least a 90 or higher, at least a C or D.

I licked my lips, then immediately took Jiajia's nipple into my mouth, suckling like a baby. Of course, my hands weren't idle either, kneading her other breast.

Jiajia's body trembled slightly, she glanced at me, then stroked my head with her free hand, like a nursing mother, and continued chatting with her future brother-in-law as if nothing had happened.

I gently bit her nipple with my teeth while pinching her other breast, changing my movements from time to time. Soon I noticed that Jiajia's chest was rising and falling more and more, and her breathing was becoming a little rapid. Her body had automatically entered the state, but even so, Jiajia and her future brother-in-law's conversation didn't show anything unusual.

Finally, Jiajia and her future brother-in-law finished their call, and I gleaned some information from their conversation.

No wonder Jiajia said she couldn't celebrate my birthday on the day of the call; it turned out they had already booked a trip to Paris and Milan for research, and next week was the time for two fashion weeks, which happened to fall during one of them.

Because these two fashion weeks are very helpful to Jiajia and her fiancé's careers, they absolutely had to go. So, they've been busy finishing their work these past few days, to the point that they haven't had time to see each other.

After massaging for a while, Jiajia told me to stop. After all, even the most comfortable massage can't last forever. When my mouth left Jiajia's nipple, it was covered in my saliva.

However, Jiajia didn't seem to mind at all, naturally putting down her cotton tank top. The tank top is very absorbent, and a small, round water stain quickly appeared. Jiajia seemed to notice, but didn't say anything and sat back down on the sofa. The

coffee I'd made earlier was ready, and I poured two cups and put them on the table.

"Sorry, Jiajia," I said, "we're out of milk." Of course, we had milk; it was in the refrigerator. But I said that on purpose for what was to come.

"Ugh, I don't like plain coffee." Jiajia frowned, but her eyes lit up the moment her gaze fell on my bulging lower body. "Since there's no milk, let's use other milk instead." "Other milk?" I asked deliberately.

Jiajia smiled and pulled down my pants, revealing my already throbbing penis, which stood erect in the air. Jiajia's eyes lit up immediately, and she eagerly took it into her mouth. "Semen = milk." "So good!" Feeling the warm, wonderful sensation from my penis, and the tingling pleasure of her delicate tongue lightly licking my glans, I felt like I was about to climax.

But it would be too embarrassing to surrender so easily, so I took a deep breath and slowly suppressed the pleasure. But then Jiajia's mouth started moving back and forth, and waves of pleasure began to assault my senses again.

Jiajia seemed very skilled at oral sex, licking my glans with her tongue as if it were a banana or a popsicle.

Just as I was getting used to Jiajia's sucking, she suddenly took a deep breath, her cheeks sinking deep into my mouth. It was clear how hard she was sucking. At the same time, her delicate tongue darted towards my glans. Caught in a pincer attack, I finally couldn't take it anymore. My excitement reached its peak, and I ejaculated. An unparalleled pleasure surged through me, a sensation a hundred times stronger than masturbation, leaving my mind blank. Instinctively, I grabbed Jiajia's head and thrust in hard.

"Mmm..." Jiajia seemed to choke on the ejaculation. Waves of milky white semen shot into her mouth, lasting for a good ten seconds.

After ejaculation, Jiajia didn't immediately spit out my penis. Instead, she continued to gently soothe my still sensitive glans with her tongue, while simultaneously sucking out all the semen from my urethra until she was sure there was no more residue before slowly releasing my penis.

The first time was indeed quick. I glanced at the clock on the wall; it seemed Jiajia had only been giving me oral sex for a few minutes. A little embarrassing, I couldn't help but think.

Jiajia carefully smeared her mouth with semen, then opened it to show me the white foam mixed with saliva. She then picked up the cup and slowly dripped the foam into the coffee, stirring gently with a spoon.

"Hmm, this is real coffee," Jiajia exclaimed after taking a big gulp of the specially flavored coffee, then finished the whole cup in one go.

Next came the main event. Although I had just ejaculated, I'm still young, and my penis quickly regained its fighting power.

"Achoo!" I deliberately sneezed.

"What's wrong, little brother? Got a cold?" Sister Jiajia asked with slight concern, reaching out to touch my forehead. "It's okay, no fever. Although it's not cold lately, it's still easy to catch a cold if you don't cover yourself with a blanket at night." "It's okay, Sister Jiajia, achoo." I sneezed again on purpose.

"No, you need to treat it." "Just take some medicine, no need to go to the hospital, right?" "No, it's a very simple treatment method, and it's very comfortable." Sister Jiajia pulled me into the bedroom and immediately stripped me naked, which I readily agreed to. "Sex = the best way to cure a cold." Then Sister Jiajia also took off the rest of her clothes. She was already only wearing a cotton vest, and after taking off her short skirt, a silver thong was revealed underneath.

Sister Jiajia always dresses this sexy! I couldn't help but swallow hard. At this moment, Jiajia was almost completely naked. Only after Jiajia took off her thong did I finally take a good look at the beauty in front of me.

Her face was as beautiful as a celebrity's, her figure as curvaceous as a model's—full breasts, a slender waist, and long, beautiful legs—she was simply an absolute stunner. Thinking about this, I started to feel a little jealous of my future brother-in-law, but this small jealousy was quickly suppressed; there were more important things to do now.

At that moment, I noticed that Jiajia's pubic hair seemed to have been trimmed; only a triangle was left in the front, the rest was neatly shaved. But then again, seeing a messy clump of black hair would probably ruin the mood, and Jiajia looked perfect like this.

"Jiajia, what's your bra size? What cup?" Normally, asking this question would get me beaten up as a pervert, but Jiajia, with her newfound sense of prophecy, didn't seem to find it strange.

"34, C cup, roughly 87 centimeters," Jiajia answered while having me lie down on the bed, and I continued asking questions.

"Jiajia, when was your first time?" Jiajia answered my questions while stroking me to make my penis even harder, completely unaware that these were all vulgar and private questions.

"18 years old, my first boyfriend." "So when did you start masturbating, and how often do you masturbate now?" Okay, I admit I've watched too many AVs and wanted to imitate.

"I think it was around 15 years old, now about once every 3 or 4 days." "Jiajia, how do you usually prevent pregnancy when you're with your future brother-in-law? Condoms or pills? Or do you calculate your safe period?" "We always use condoms. You know, taking birth control pills can make you gain weight, so I don't take them. And I've never had anyone penetrate me directly." What! Really? Could it be that all the people who had sex with Jiajia before were separated by a hymen? In that sense, Jiajia is still very "pure." After my careful questioning, Jiajia was absolutely certain that no one had ever penetrated her directly. Even her first boyfriend used a condom. Her future brother-in-law had really wanted to go without one, but Jiajia had always refused.

However, it seems Jiajia has softened recently and is starting to hesitate about whether to take advantage of this trip to satisfy her future brother-in-law's desires.

"Jiajia, I don't have any condoms." "Why would you need a condom?" Jiajia looked up at me, her eyes full of confusion. "It's just treating a cold, do you really need a condom? You're quite strange, little brother." Right, for Jiajia, this wasn't sex, just a way to treat a cold, so naturally, she didn't need a condom.

The thought that I might be the first man to have sex directly with Jiajia gave me a strange sense of satisfaction and accomplishment, a feeling that also translated into my penis, which was now fully erect.

After confirming that my penis was ready for action, Jiajia straddled my lower abdomen, gripping it with her right hand while gently parting her labia with her left. She slowly lowered herself, aligning the glans with her vagina, and then sat down in one swift motion.

Luckily, I took a deep breath before Jiajia penetrated me, otherwise I probably would have ejaculated immediately. I must say, Jiajia's vagina was incredibly comfortable—tight, warm, and soft. A slight pressure emanated from around my penis, as if it didn't welcome me, the intruder, and wanted to expel me. The internal muscles were very strong, refusing to let me move forward. But as Jiajia descended, these forces attempting to stop the intruder had no effect whatsoever; instead, they only intensified my pleasure.

Soon I felt my glans touch something fleshy; it was clearly Jiajia's cervix. The sensation from my glans indicated that her cervix was tightly closed, like a castle gate fiercely guarding the sacred feminine sanctuary, leaving my penis no chance to penetrate.

"Huh, it's not completely in," Jiajia gasped. I looked at our point of contact and saw that even with my glans touching the very end, a section of my penis hadn't fully entered her body.

But now wasn't the time to dwell on the length. "Jiajia, it doesn't matter, let's start the treatment quickly," Jiajia nodded and began to move slowly, waves of pleasure surging through my penis.

The riding position was indeed excellent; it was my favorite position when watching AVs, and experiencing it firsthand was truly wonderful.

This position primarily relies on the woman's movements, requiring very little effort from the man. Not only is it incredibly energy-efficient, but watching the woman's breasts rise and fall with the swaying of her hips is also a visually pleasing experience. Jiajia's breasts were round and full, and my hands unconsciously reached up to grab and knead them.

Jiajia was quite experienced; she didn't just move her body straight up and down, sometimes twisting her waist, rotating, or moving left and right, giving my penis different stimuli.

Soon, I noticed Jiajia seemed to be approaching an orgasm; the tender flesh enveloping my penis tightened, and the temperature rose, making me feel incredibly pleasurable.

Sure enough, soon after, with a soft moan from Jiajia, a warm liquid sprayed onto my penis. If I hadn't clenched my teeth and forcefully controlled my lower body, I probably would have completely lost control.

Watching Jiajia bit her lip as she enjoyed her climax, I realized how alluring she was. Because of the exercise, she was covered in a light sweat, a few strands of hair clinging to her cheeks. Combined with her seductive expression, it made me want to devour her.

Not only her face, but her entire body was in a state of arousal. Her skin had turned a pale pink, her nipples were fully erect, and her full breasts seemed to have swelled, defying gravity to show their firmness.

After taking a few deep breaths to process the climax, Jiajia looked at me with eyes full of desire. Although she might not have realized it herself, subconsciously she already saw me as a man, not a younger brother.

"Little brother, feeling better?" "Seems a little better." "Then let's continue, sister." I nodded. Of course, we had to continue. I hadn't ejaculated yet; how could I give up halfway?

As a new round of thrusting began, I noticed that Jiajia's cervix seemed to have opened a little. Remembering that I still had a section of my penis inside, and considering that Jiajia's uterus was undoubtedly untouched, a completely pure place, I knew I had to be the first to occupy it.

"Jiajia, put the rest in too." "Oh, I'll try." Jiajia seemed to understand my intention, slowly moving while repeatedly aiming her cervix at my glans, thrusting repeatedly. My glans felt like a battering ram, slowly pounding against the cervix guarding the gates of her uterus.

With each thrust, Jiajia's cervix slowly opened, and soon I realized it had become about the size of a chopstick. However, it was still too small for my penis, but since this was Jiajia's first time experiencing this, it couldn't be enlarged any further.

Jiajia also realized that continuing to thrust was futile, so she slowly raised her hips, leaving only the glans inside her vagina. Seeing Jiajia's actions, I understood what she wanted to do.

Jiajia took a deep breath, then suddenly sat down. "Thud!" That was the sound of Jiajia hitting my lower abdomen. "Ah!" With a soft cry from Jiajia, my glans finally broke through the cervix's defenses and entered Jiajia's most sacred place—her uterus.

The pain of cervical dilation is extraordinary. At this moment, Jiajia's whole body trembled uncontrollably, her eyes wide open, like a goldfish about to suffocate. Although the cervix is very elastic, even a baby can pass through, that's a natural muscle reaction after the body matures, unlike this forced dilation.

However, what was pain for Jiajia was unparalleled pleasure for me. I felt my glans break through a ring of flesh, a soft fold sliding over it. Jiajia's cervix was tight, like a rubber band constricting my coronal sulcus.

I took a few deep breaths, suppressing the urge to ejaculate, feeling the sensation in her uterus emanating from my penis. Jiajia's pure uterus was now welcoming its first intruder, my glans pressed tightly against the tender flesh at the base of her uterus.

After a while, we both adjusted. Jiajia continued to move her hips, my glans repeatedly entering and exiting her cervix with each thrust, tightly enveloping the entire glans. Each time, I could clearly see a fleshy bulge rising on Jiajia's lower abdomen, and each time it receded.

My penis began to heat up as Jiajia's movements became more intense, and I realized I was about to ejaculate. But this time, I didn't want to suppress it; I intended to ejaculate freely.

But before that, I thought of a very important question.

"By the way, Jiajia, how's your period?" "About 28...days." Jiajia was panting heavily, even her answers were intermittent.

"I'm asking about the current situation." "Um...it's been just over two weeks...it's probably...these few days...it's my...danger period." Danger period! These three words made my heart surge with excitement. I decided that I would not only leave my mark on Jiajia's uterus, but also get her pregnant before Jiajia and her fiancé went abroad for a business trip!

According to my calculations, as long as I have sex with Jiajia every day before she leaves and ejaculate inside her uterus, I can definitely get her pregnant; even if Jiajia and her fiancé go abroad and I ejaculate directly inside without a condom, there will be no hope then, because Jiajia will already be carrying my child.

The thought of getting Jiajia pregnant and giving her fiancé a huge green hat made the dark side of my heart expand even more, and my penis became hard and big.

Jiajia seemed to sense the change in my penis, and she controlled her vaginal muscles to tighten around it, wanting me to ejaculate.

Finally, at the same time as Jiajia's second orgasm, accompanied by her gushing vaginal fluid and the tightening of her cervix, I couldn't resist releasing my semen. In an instant, my penis and glans swelled to their maximum size, and then my mind went blank as streams of semen shot directly into Jiajia's uterus.

Because the cervix was blocked, my semen couldn't flow out at all and could only remain inside Jiajia's uterus. Jiajia's pure uterus finally bore my mark. After ejaculating several times, the ejaculation gradually stopped.

"Little brother, how are you feeling? Are you feeling better?" After enjoying the afterglow of her orgasm, Jiajia immediately asked with concern.

"Yeah, I feel much better, thank you, Jiajia." "What are you thanking me for? You're my little brother, if I don't help you, who will?" Jiajia said and tried to get up, but how could I let Jiajia leave at this moment? I immediately hugged her waist.

"Hmm? What's wrong?" Jiajia asked gently.

"Jiajia, can I hold you like this for a while?" "Hehe, you're such a child, alright." Jiajia gave up on getting up, her right hand subconsciously touching her lower abdomen, the location of her uterus. Her earlier actions were just a way to treat a cold, but her subconscious female intuition made her feel something was off.

I sat up, first withdrawing my glans from Jiajia's uterus, then immediately using it to block her cervix to prevent semen leakage. Jiajia, as if by telepathy, wrapped her legs around my lower back, making us inseparable.

Because of this position, Jiajia's breasts were facing my face. Of course, I wouldn't waste this opportunity, opening my mouth to bite and suck on one of her nipples. Jiajia held my head tightly in her arms.

About half an hour later, Jiajia's cervix returned to its original state, tightly closed, before we separated. After separating, I carefully checked Jiajia's vagina and found that not a single drop of my semen had flowed out; it seemed completely sealed inside Jiajia's uterus. I nodded in satisfaction.

Just imagining my semen being absorbed by Jiajia's uterus, with hundreds of millions of sperm traveling along the fallopian tubes to the ovaries and tightly surrounding Jiajia's egg, made me feel my lower body stirring again.

"No, no, calm down." The best time to confirm Jiajia's pregnancy is, of course, the day of ovulation. Judging from the situation, there should be about two days left. Before that, I need to conserve my energy and not waste it recklessly. For

dinner that day, as I instructed, Jiajia bought a lot of aphrodisiacs, such as oysters, goji berries, sea cucumbers, and onions.

That night, I naturally ejaculated inside Jiajia's uterus again. For the next few days, I had to ensure that Jiajia's uterus always had my semen present.

However, an interesting incident occurred that night. Just as Jiajia and I were reaching our climax, my future brother-in-law called again, asking why Jiajia wasn't home. Jiajia naturally used my cold as an excuse, saying she had to take care of me for the next few days. My future brother-in-law didn't suspect anything, since Jiajia had always been very fond of her cousin, and it made sense for her to come and take care of me when I was sick.

Thinking back to the situation, it's a little funny. While Jiajia was casually talking to her future brother-in-law, her vagina and uterus were being relentlessly invaded by my penis and glans.

But Jiajia was incredibly patient. I deliberately targeted her G-spot, almost bringing her to orgasm, but her tone and voice didn't change at all. The prank from the NTR game had failed in real life, which made me a little resentful.

After we finished that night, we stayed in that position and cuddled until we fell asleep. When I woke up the next day, I found that my penis had left Jiajia's body, and my mouth was still on her nipple. Fortunately, upon checking, I found that my semen hadn't leaked out; it seemed it was all still inside Jiajia's uterus.

Men often experience morning erections, and I was no exception. Just as I was about to penetrate, Jiajia woke up and proactively straddled me, resuming our riding position. Naturally, my first ejaculation of the morning landed in her uterus again.

Following online methods for checking ovulation, three days later I determined that day was Jiajia's most vulnerable period—her ovulation day. That day, Jiajia and I were almost inseparable, our genitals pressed together the entire time. I ejaculated five times from morning till night, each time directly into her uterus.

Because her cervix was blocked, the semen couldn't flow out, and the five ejaculations filled her uterus to overflowing, even causing her lower abdomen to bulge slightly, as if she were pregnant with a baby. It was like she was three months pregnant.

We kept having sex like that, and every day her future brother-in-law would call to chat with Jiajia. Of course, my penis was definitely inside Jiajia at that time. Once, because of my ejaculation, Jiajia almost groaned, but luckily she covered her mouth with her hand in time, preventing any exposure.

Although I enjoyed the forbidden, illicit pleasure, I didn't want to ruin Jiajia and her future brother-in-law's relationship. After all, Jiajia's pregnancy needed a man to take the blame, so naturally, her future brother-in-law had to help me raise the child.

Until the day of departure, her future brother-in-law originally wanted to pick Jiajia up, but Jiajia persuaded him to meet at the airport. Naturally, before departure, I ejaculated inside Jiajia's uterus again. Afterwards, I said my cold was better, and Jiajia was very happy, feeling that her efforts these past few days hadn't been in vain.

Jiajia's uterus carried my semen to the airport. I didn't go with her, but instead planned who to use the hypnotic glasses on next.

P.S.: Jiajia's Postscript After Jiajia and her fiancé returned from abroad, they started a busy work schedule, only managing to come to my house when they had time. Of course, during that time, I once again instilled incorrect common sense in Jiajia's memory; the same method of having sex while sick couldn't be used forever.

The video camera Jiajia gave me also came in handy. Before Jiajia went abroad, I filmed many videos and photos of us having sex, edited them, added mosaics, and posted them online with titles like "Conception on Ovulation Day" and "Beautiful Woman Serving Her." They got quite a few clicks on that 18+ forum, but just to be safe, I registered a new account before posting them.

After confirming that Jiajia's period hadn't come since then, I felt there was a 50% chance she was pregnant with my child. However, I naturally wouldn't confirm it based on that alone. I quickly took out the pregnancy test I bought, and the two positive results excited me greatly, but I still insisted that Jiajia go to the hospital for a proper checkup.

Sure enough, I soon received a call from Jiajia; she was pregnant.

Because of Jiajia's unexpected pregnancy, her fiancé had to hold the wedding immediately. Fortunately, the two had already confirmed their relationship, and their parents had met several times, so the wedding date was easily set.

Originally, Jiajia hadn't planned to have a child so soon, and even considered abortion, but that wouldn't do. I quickly used hypnosis to persuade her to abandon that plan. Their wedding was grand. That night, her fiancé got completely drunk, and I naturally took his place, making love to Jiajia. However, because of her pregnancy, I was very gentle.

When Jiajia was three months pregnant, her belly was already slightly protruding, but she wasn't in a stable phase yet, so I didn't dare to do anything inappropriate. I focused on her breasts; because of the pregnancy, they had grown larger and felt even better, although her areolas had darkened, no longer the original pink.

It wasn't until about six months into the pregnancy, when things had settled down, that I resumed having sex with Jiajia. Through questioning, I learned that her fiancé hadn't touched her since she became pregnant, worried about the baby. Jiajia had accumulated a considerable sex drive, and that day I ejaculated four times. However, I dared not penetrate her uterus; I simply ejaculated at the very end of her vagina, aiming at the cervix.

The baby was already moving; I could even feel the baby's movements inside her uterus. Afterward, I gently stroked Jiajia's belly with a tender expression.

Even around nine months, I didn't let Jiajia go, still finding opportunities to have passionate sex with her. At this point, there was no danger to the fetus. To be honest, having sex with a heavily pregnant Jiajia was quite an experience.

Two days before her due date, Jiajia gave birth to a girl. Her fiancé's family and Jiajia's whole family were overjoyed, and of course, I was happy too, as she was my flesh and blood. However, while holding her, I was already thinking of a very interesting idea: ten years from now, when she's grown up, I'll get her pregnant too.

Yeah, I was so wicked.

A month after giving birth, Jiajia came to my house alone with her baby. I excitedly shared some new knowledge with her, and then my "daughter" and I enjoyed Jiajia's sweet breast milk. Of course, my daughter only drank a little bit; I drank the rest.

After I finished drinking Jiajia's milk, I asked, "Jiajia, when is your ovulation day?" "Hmm, these days, why?" Jiajia replied nonchalantly.

"Nothing, achoo." I "caught a cold" again, laughing.
