少子化対策の研究をする、二人の女の話-EN_beginning 30% (Pixiv Fanbox)

　The year is 20XX. 　Japan was suffering from an extremely low birthrate. 　Not only had the late marriages and aging society with fewer children continued from the previous century, but the global epidemic of infectious diseases had also skewed the population pyramid to an extreme degree. 　The impact of infectious diseases was particularly pronounced in the declining male population, with the male-to-female ratio drastically out of the norm at 34:66, with only one-third of the population being male in Japan. 　Japan was still moving slowly, even though it knew it would soon perish, but then a radical population recovery movement began to emerge. 　The argument was that if women could reproduce with each other, "population decline itself could be prevented. 　In other words, they proposed that women should procreate with other women, leaving the disappearing male population behind. 　This opinion was initially silenced as absurd ......, but science had already suggested that this was possible, and the radicals' opinion gradually became a groundswell. 　The radicals also established an institute that primarily studied female reproduction. 　One genius scientist belongs to that institute. 　Sara Minami (MINAMI, Sara). 　She is one of the world's top researchers on female reproduction and intercourse, and is also an extreme pragmatist. As soon as she completed her theory, she wanted to conduct experiments. 　Meanwhile, infectious diseases were infesting other countries, and Japan's neighbor, South Korea, was in the same situation as Japan. 　Korea was also similar to Japan in that it had a declining birthrate and an aging population. 　In Korea, too, an institute for research on female reproduction was established, and it too had world-class researchers. 　Kim, Si-Ra. 　Although Sara Minami and Si-Ra Kim did not know each other directly, they were aware of each other through academic journals. 　They were working on the same kind of research, and their progress was almost equal to that of each other. 　If it is said that they were rivals, it is not quite true. 　Rather than being rivals, they were more like adversaries. 　I was the one doing the best research and achieving the best results in this field, while my adversary was achieving similar results at about the same time. 　Their admiration was halved, and their frustration at the need to advance their research doubled. 　One day, however, they completed a theory at exactly the same time. 　A theory that could derive the optimal solution for reproduction between women. 　Sara and Si-Ra were impatient when they came up with this theory. 　The other party might reach this theory in the not-too-distant future. 　If they waited for the approval of the national ethics committee before conducting experiments, they might be outwitted. 　Thinking of this, they could not wait. 　Sara and Si-Ra decided to put the theory into practice, using themselves as the test subjects. 　One week later. 　Sara contacted Si-Ra for the first time. 　She said she just wanted to meet him. 　A few hours later, Sara and Si-Ra met each other at a hotel. Sara said, "Nice to meet you ......, but it doesn't feel like a first meeting. I'm Sara Minami. I think you know me well. 　She was dressed in a white shirt and jeans, but her beauty was clear. 　She had a well-defined face and long black hair that fell to her thighs. Her breasts protrude out, but her waist is tightly squeezed. Si-Ra said, "Nice to meet you, in a manner of speaking. I am Kim Si-Ra. You probably know me, too. 　Si-Ra was dressed the same way, coincidentally. Shirt and jeans. While she was dressed casually, her long feminine hair, large breasts, and slender waist were no less feminine than Sara's. Sara: "Today, I have something to tell you more than anyone else in the world. Si-Ra: "Oh, really?　Actually, I have something to tell you, too. Well, I guess you could call it a 'declaration of victory'." 　Sara's eyebrows twitched at the word "declaration of victory. Sara "What a coincidence, isn't it?　I was going to declare victory, too. 　Si-Ra's eyebrows moved this time. 　Both of them, sensing the possibility that they had arrived at the same theory and conclusion based on their past experiences, silently pulled down their jeans and then their shorts as well. 　There it was, the penis, an organ that women are not supposed to have. Sara said, "Yes. That's right. ......" Si-Ra said, "I knew this would happen. ......" 　They both expected this to happen. 　The actuality that this is the best way to make reproduction possible amongst females has been pointed out many times before. 　It is safe to say that not only Sara and Si-Ra, but also researchers all over the world are working toward this outcome. Sara: "But what about its performance?" Si-Ra: "That, of course, we'll have to find out." 　Sara's hand touches Si-Ra's meat stick, 　Si-Ra's hand touches Sara's pole. 　Neither of them can resist the desire to confirm that their own genital performance is better than the other's. Sara: "You seem to be feeling it. Si-Ra: "I'm sure you have good sensitivity too." 　Sara and Si-Ra's hands are gentle and careful, and they light a fire in the other's sexuality. The penis begins to swell as the fire is slowly nurtured by the hands. 　Sara's and Si-Ra's penises are getting bigger and bigger as if they are competing with each other. They are facing upward and are already as big as the navel. 　The size is heinous. 　Not only the simple length, but also the thickness is more than enough, the glans is bigger, and the gills are higher. 　However, there is no superiority found in their heinous size. 　Sara and Si-Ra's penises are exactly equal in size, including length, thickness, and glans tension. 　At the same time, they overflow cowper from their bell mouths, mix them together, and smear them on each other's glans. 　It reminded me of a predator drooling to devour the other. Sara: "After all, if we're going to check performance, this is the only way, right?" Si-Ra said, "Of course. It's just to check the performance. 　As if to make excuses, they both sat down and pointed their glans at each other's labia. Sara "I've been dreaming about it for a long time. ...... Si-Ra." Si-Ra: "Yes, me too,...... Sara." Sara "...... this time when I can rape this fucking cocky Korean and sire him with my superior Japanese genes!" Si-Ra: "...... I can rape this fucking arrogant Japanese and sire him with my superior Korean genes, this time!" 　Then, as the two men thrust their hips forward, their huge penises collide with each other, bouncing off to the left and making their lower abdomens close together. Sara and Si-Ra: "Hukku...... mmmm......" Sara: "Don't run away, Korean ......!" Si-Ra: "You saved my life, Japanese......!" 　They put their arms around each other's thin waists and reasserted their aim. 　This time, Si-Ra moved a split second ahead. 　Si-Ra's penis thrusts into Sara's labia, but Sara's huge cock clears it just in time. Si-Ra "Fugu! 　Sara's phallus is thrust out toward Si-Ra's labia, which are now out of position. 　However, Si-Ra, in this predicament, also hurriedly shakes her hips and strikes Sara's phallus away with her huge cock. Sara: "Uggg!" 　The two began to slam each other's penises against each other intensively. Sara said, "Mine!　Ugh!　My Japanese phallus is stronger!" Si-Ra: "Mine!　Ugh!　My Korean penis is stronger! 　With a bang, bang, thud, and thud, they smash each other's penises against each other, trying to make the other one shrivel up with the pain. 　However, the hostile awareness of each other is so strong that the reality that they are beating the other's penis and making it scream excites them, and both penises do not shrivel up. Rather, they become belligerently hard. Sara and Si-Ra: "You perverted people who get off on being punched in the dick ......!" 　In any case, it is not likely to be settled at this point. 　Sara and Si-Ra grasp their own penises and thrust them forward. 　Having come this far, they no longer felt that they could insert themselves alone. Sara: "We have no choice. ......" Si-Ra: "Let's put it in each other." Sara: "That seems to be the only way. Still, though, a good Japanese dick will totally fuck a Korean cunt." Si-Ra: "Hush up. It is the superior Korean dick that rapes Japanese cunts." 　They intentionally pointed their glans at each other's labia and did not disturb each other. 　Of course, I don't like being inserted. 　But more than that, I didn't think my labia would be defeated by the other's penis, much less my own labia. Sara: "Okay, here we go." Si-Ra: "Okay. ......" Sara and Si-Ra: "Se-no, no ......, ah-oh!" 　Sara's Japanese meat stick pushed through Si-Ra's Korean vagina. About half of it is in there. 　At this time, half of Si-Ra's Korean pole also pushed through Sara's Japanese vagina. 　At that point, both of them were cracking up and their mouths were gaping. 　It was thick, hot, and felt good! 　The male penis that entered them was like a natural enemy of the vagina. 　It surely stimulated her vagina and stroked the most sensitive part of her body with its gills. 　On the other hand, the meat stick was not free either. 　The tightness of the flesh pressed against the phallus. 　The wet and slippery vaginal flesh stirs, inviting the penis to go deeper and deeper. Sara "Ah, ah, ah, ah, ah! Si-Ra "Oh, oh, oh, oh! 　My hips move forward on their own. 　She is receiving the greatest stimulation, both in terms of being fucked by the penis and by the labia. 　The rod rubs the vaginal wall, then reaches the cervix, still pushing up the uterus with the extra length of the rod. 　Both the vagina and the penis ...... receive too much stimulation, both as a woman and as a man. 　Sara and Si-Ra instinctively held each other, trying to withstand the stimulation.
