[skeb]特別なトイレを使う双子の続きの話-EN #1 (Pixiv Fanbox)

　The twins Rina and Sana Tezuka were once completely absorbed in online games. Their flexible lifestyle as university students living together made this lifestyle worse. However, at a certain point, their lives changed drastically. 　The amount of time they spent playing online games, which had previously taken up so much of their time and money, was cut in half, and they began to spend the rest of their time together. This was not something that could be described as a good thing, as they were close friends. Rina and Sana, who are identical twins, began to have sex with each other. As they were both women, they had no worries about getting pregnant, so they took advantage of this and sought each other out. Rina: "Sana, how are you doing? Are you getting close?" Sana: "Yeah, I'm good. Rina." 　What's more, their sexual activity was extremely unusual. The fact that they were of the same sex and twins made it unusual enough already. However, their perverted nature was not enough to explain it. Rina, who was wearing a sweatshirt as her loungewear, began to take off the top part (sweatshirt), and Sana took off the bottom part (sweatpants). 　The twins undressed half of their bodies each, as if they were contrasting each other. Sana forcibly twisted her lower body into Rina's sweatpants. The two girls' chubby right and left legs seemed to be squeezed into the pants. 　And since neither of them was wearing any panties, their private parts were pressed up against each other from the front inside the sweatpants. When this happened, Rina then turned up Sana's sweatshirt and twisted her head and upper body inside. Their well-endowed breasts and firm bodies were intertwined and pushed into the sweatshirt. 　The collar was already loose... or rather, it had been altered so that if the buttons were undone, it would not be too tight for the two of them to push their heads through. Rina and Sana were forced to be close together from top to bottom, and they could not separate. So they buried their faces in each other's necks and took deep breaths, enjoying the smell of the other person. 　As twins, I think they should smell similar to each other, but somehow they can recognize each other's scent. This is the scent. I like this scent. They breathe in each other's scent, filling their lungs with it, and then they begin to wriggle. 　Their skin rubs against each other, and they feel good. These small pleasures gradually light up their bodies, making their nipples hard and their labia moist. Their nipples collide, and their labia collide. Rina and Sana: "Huu, nn..." 　Sweet gasps of breath escape. The voices they make now carry a pleasure that makes their ears and brains feel like they're being shaken. Naturally, they want to hear more of those voices, and the two of them begin to rub their bodies together... at this time, their lower halves come together and start rubbing against each other. 　Their pubic hair rubbed against each other, their clitorises pushed against each other, and their labia licked each other as they clung to each other. The sound of their bodies being completely wet was the best proof that they were both feeling it. 　They help each other by pressing their labia against each other, preparing for the upcoming act. For what they are about to do, it is essential that their lower halves are in complete contact with each other. The fact that they can confirm this just by feeling shows how accustomed they are to this act. In this way, they connect their urethras and anuses as usual. Rina: "Is it okay...? Sana: "Yeah, it's fine..." And in the next moment, their faces relaxed a little and they were intoxicated by the pleasure of "release". The muscles that had closed off their urethras opened up, their bladders contracted, and they tried to release the fluid inside. Rina: "Today, I'm going to make you drink it!" Sana: "No, you're the one who's going to drink it!" The urine runs down Rina's urethra. Normally, this liquid would be released from the urethral opening. However, that urethral opening is blocked by the urethral opening of the woman in front of her, Sana. 　Rina's urine, which rushes into Sana's urethral opening, flows back up Sana's urethra. It then reaches Sana's bladder. Sana's bladder, which was originally contracting in an attempt to urinate her own urine, is forced to expand by Rina's urine flowing back up, and she writhes in agony. 　Sana's eyes open wide and she trembles as Rina's urine is forcibly poured into her. Sana: "Hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii 　Rina's urethra was forcibly filled with Sana's urine, and it even reached Rina's bladder. Naturally, Rina also had to endure the torment of her bladder being forcibly dilated as it contracted to urinate. Rina: "I'm peeing, but...!" Sana: "My bladder is in so much pain..." 　Despite the fact that both Rina and Sana were urinating, their bladders were being forcibly refilled with urine, and the pain in their bladders did not ease at all. In fact, the abnormal situation of being supplied with urine even though they were urinating was far worse than the pain of holding back urine normally. 　In Rina's bladder, Rina's urine was supplemented with Sana's urine, and the two mixed together and became uniform. By now, Rina's bladder was in a state where Rina's urine and Sana's urine were mixed together in equal parts. The exact same thing was happening in Sana's bladder. 　The two of them were urinating into each other's bladders, and then being urinated into in return, and the contents of their bladders were being swapped around and mixed together, like they were being stirred to make them more uniform. Rina: "I've always said it...! I don't need your pee, Sana!" Sana: "That's what I'm saying...! You just need to drink my pee from my bladder, Rina!" Rina: "I definitely don't need this dirty stuff...!" Sana: "I definitely don't need it either...!" 　Although they are both rejecting each other's urine, their urine is mixed together and poured into each other's bladders as if that doesn't matter. The two of them, who know that there will be no end to this fight, continue to fight. After checking the angle of their hips, they now focus their strength on their lower abdomens. 　Their tightly-clenched anuses twitch as they prepare for the upcoming action. Rina: "You should have just obediently drunk the pee..." Sana: "You should regret having to fight with your butt..." Rina and Sana: "...Huff! 　They squeeze their stomachs and expel their feces. Of course, the destination of the expulsion is the other person's anus and intestines. The anus slowly opens and the contents are pushed out. Naturally, the other person also defecates. The two people's feces collide with each other and are forcibly rubbed against each other and pushed into the other person. 　It's the same as when you urinate, but this "feeling of being pushed in while you're expelling" is agonizing and unpleasant. The things in your stomach are pushed out, and then things other than your own are pushed into your intestines, which should be making you feel better. The pleasure of being released and the pain of being forced to accept things you don't want are making Rina and Sana's heads spin. 　When one is pushed in, the other pushes back. Just like urine, the two girls' stools are also homogenized within their bodies. Their bodies are screaming with joy at this filthy, endless, abnormal act. Rina and Sana: "Mmm, mmm... ahhhhh!!!" 　The labia were dripping with love juice of joy, and the clitorises had become bigger than ever. Due to their positions, it was unavoidable that they couldn't rub their clitorises together. Anyway, the two of them were writhing in agony and pleasure together in this abnormal situation. Rina: "Pervert toilet girl...!" Sana: "Don't say that to me, you're my personal pervert toilet girl!" Even the worst insult of being a toilet girl was a pleasure that made their brains numb. Rina: "Sana, Sana, the toilet for Rina's exclusive use, Sana ♥" Sana: "Rina, Rina, the toilet for Sana's exclusive use, Rina ♡" When they hurl such insulting words at each other's ears, they feel a pleasure that makes their bodies shiver. Rina: "That's so unfair... you're just a toilet, Sana...!" Sana: "That's so unfair... you're just a toilet, Rina...!" 　They sweetly violate each other's eardrums, and the two of them are easily brought to climax. They let their love juices overflow and rub them against each other's labia. They expel a particularly large amount of urine, and it is forcefully supplied to the other person's bladder. The feces stop moving at this moment, but otherwise they slowly mix together and go back and forth through each other's intestines. 　And this time, the great pleasure brought about a slight change in their bodies. The breast milk spurted out forcefully from their nipples, wetting each other's chests. Rina and Sana, who had never produced breast milk before, were surprised. Rina: "What, my boobs...? Is that it?" Sana: "Yeah, it looks like it. Rina, did it feel that good?" Rina: "That's annoying. You did it too, Sana. You must have felt good, right?" 　While they were chatting like that, they took a look at the liquid on their chests with their fingers. They had been crushing their nipples together, but when their bodies twisted, their lower breasts were pushed together and turned slightly upwards. The milk that gushed out in that state fell straight onto the other person's pure white breasts. 　No, but still... this is too erotic. Have our own pleasure finally grown to the point where we're squirting breast milk at each other? The nipples of the other person in front of me... covered in the breast milk that I myself have squirted out, and still trembling with excitement, they look incredibly erotic. 　Their nipples, which had become engorged and enlarged and were now wet with milk, were so erotic that they couldn't help but stare at them. Even though they weren't pregnant, they were still producing milk. However, at this point, their thoughts turned to a certain matter. Rina: "Sana... your breasts came out, right?" Sana: "Yeah, I guess so. Rina's come out too, though." Rina: "Hey..." Sana: "Yeah, I know. If breast milk is a liquid that can be poured out... then I can pour it into you, right?" Rina: "That's right. You can pour it in, right? Will you drink it, Sana?" Sana: "You're the one who's going to drink it, though, right, Rina?" 　They were crazy. If you consider squirting breast milk to be "excretion", then it's natural for them to pour it into the toilet woman in front of them. Rina and Sana shake their huge breasts and adjust the position of their nipples. Like before, they make their nipples face each other. 　However, unlike before, overlapping their nipples, which were now more assertive, was a little more difficult. Even when they brought their large, breast milk-slicked nipples close together, they moved as if they were intertwined with each other, and the pleasure that welled up from their sensitive nipples distracted them from their goal.
