[skeb]特別なトイレを使う双子の続きの話-EN #2 (Pixiv Fanbox)

Rina: "Be quiet...!" Sana: "Give me your nipples...!" 　Despite the sweet stimulation causing them both to struggle, somehow their nipples ended up colliding head-on. Rina and Sana looked at each other and gave each other a light signal, and then pushed their chests forward. Rina and Sana: "Gukukuu...!" 　This is different from the urethral or anal openings, where a certain degree of tightness is possible. The two girls thrust the peaks of their protruding nipples against each other. They tried to concentrate the pressure of the flesh of their two large breasts on the peaks of their nipples and push them into each other. There was no way that their nipples, which were the same size to begin with, would be able to pierce each other. 　However, the two of them applied strong pressure to each other. The two pairs of nipples tried to penetrate each other with a grinding noise. Finally, one of the mammary glands was pushed out and slowly spread, and the nipple on the other side tried to forcefully enter it. The act of "inserting a nipple into a nipple", which seemed absurd, was also accomplished by these two people. Rina and Sana: "It's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in... it's in 　Sana's right nipple was hot, slimy with breast milk, and narrow. Rina's left nipple was being squeezed as if it were being pinched, and it felt like it was about to be crushed. On the other hand, Sana's right nipple was being forced to swallow Rina's left nipple, and the feeling of expansion was almost violent. 　The left nipple of Rina, which is being forcibly pushed outwards from the inside and is also a little rough, stimulates the inside of the vulnerable nipple of Sana with each gradual intrusion. Both the left nipple of Rina, which is being blamed, and the right nipple of Sana, which is receiving the blame, are being cornered together, and it was a situation where they would both collapse together. 　And with the other nipples - Sana's left nipple and Rina's right nipple - the exact opposite was happening. In other words, Sana's left nipple was being inserted into Rina's right nipple. 　Naturally, Sana's left nipple was being squeezed tightly by Rina's right nipple, and conversely, Rina's right nipple was being forced open by Sana's left nipple, and the inside was being rubbed, and they were both writhing in agony from the mutual torment of mutual destruction. Both of them regretted that this action was a mistake due to the tremendous stimulation. 　Neither the one inserting nor the one being inserted can overpower the other. Furthermore, the left nipple is being inserted and the right nipple is being inserted, so neither can enjoy the other one-sidedly. The mutual nipple insertion of the equal twins was a mutual sacrifice. However, this is not the end of the situation. 　The original goal was to pour breast milk into the other person's breasts... The situation was such that the breasts, which were already about to erupt with pleasure to the point of going crazy, were somehow being held back. If the breast milk in the left nipple of the person who had inserted it was released, the desired situation would begin. 　On the other hand, the right nipple would be forced to drink the milk. Although the damage was not to be ignored, I could not resist the desire to pour my milk into the other person. This was partly because the milk in my own breasts was overflowing. In this way, the milk was finally released from Rina's left breast and Sana's left breast. Rina and Sana: "Ohhh! It's coming out! It's coming out! My breasts are coming out... It's coming in! It's hot! It's coming in! 　The two of them were first intoxicated by the feeling of their breast milk gushing out. The breast milk flowed out after they forced open the milk ducts of their left breasts, which had become constricted. The pleasure of the gushing milk made their nipples tremble. Then, they writhed in agony as their partner's breast milk was poured into their right breasts. Their right breasts were already producing so much milk that they were about to burst. 　The other twin's breast milk was forcibly flowing into it. The hot breast milk that had just been made. It invaded sharply as a jet, and the lobules and lobule lobes of the right breast were violated. Even though they were twins, the feeling of having the breast milk of someone other than themselves flowing back. It was a huge wave of intense pleasure that felt as if it would drive the lobules and lobule lobes of the right breast mad. 　If it had been anyone other than Rina and Sana, these sensations would have been pure pain and suffering. What's more, it wasn't just any kind of pain or suffering. After all, someone else's breast milk was being pumped back into their own mammary glands. However, for Rina and Sana, these sensations were being converted into pleasure. The twin's breast milk being pumped into their own right breasts. 　No matter how you look at it, it's abnormal, no matter how you look at it, it's erotic, no matter how you look at it, it's the most arousing thing. Rina and Sana were enjoying the pleasure, drooling from the corners of their mouths. However, on the other hand, it was inevitable that their right breasts would become abnormally swollen and heavy. And as a completely physical reaction, their right breasts, which had been stretched to the limit, began to contract. 　No matter how much they tried, they couldn't store this much breast milk. As a counterattack, which sounded like a scream, breast milk gushed out of the right breast this time. Naturally, the destination of the flowing milk was the other person's left breast. There was a mixture of impatience, "This is bad. I have to get the left breast out of the way quickly," and a sense of expectation, "Will I be able to experience this pleasure with the left breast this time?" 　Of course, even if she tried to escape, the nipple was firmly held by the other person, so there was nowhere to escape to. Then, the milk that had been gushing out of the left nipple started to flow back towards the left nipple that had been gushing out milk until now. Rina and Sana: "Heee, iiii!!!!" 　A short scream. At that moment, the left breast began to fight back. The breast milk of both herself and her partner, which had been stored to the limit in the right mammary gland, rushed through the mammary glands at once and spurted out sharply from the nipple. The left nipple, which had been relaxed due to its previous dominance, was unable to prevent the onslaught of breast milk. 　The milk flowed in in a rush. Unable to push it back, it flowed back through the right breast's milk ducts in one go, violently hitting the bottom of the milk ducts. Rina and Sana: "Unnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn 　One after another, the milk rushed in, and one after another, the right mammary gland was made to swell up. The milk was also a mixture of their own milk and the other person's milk. Just like a bladder or intestines that mix together urine and feces and rejoice, Rina and Sana's mammary glands rejoiced. The strange sense of unity of being violated by the mixed milk right down to the mammary glands, and the masochistic pleasure. 　On the other hand, the left breast felt the masochistic pleasure of raping the other's mammary gland, and a sense of domination. The situation where Rina and Sana were raping each other's breasts with their breasts was giving them both the pleasure of both attacking and being attacked at the same time. Furthermore, that pleasure was switching back and forth at a dizzying pace. Rina: "My right breast...!" Sana: "My right breast...!" 　The right breast, which had been forced to store up breast milk to the limit, began to spurt out breast milk again due to the power of the milk flesh and the contraction of the mammary gland. The right breast, which had attacked first, was counterattacked by the left breast, and the right breast then counterattacked again. 　However, the left breast, which has been filled with a mixture of Rina and Sana's breast milk, also reaches its limit and retaliates. Rina: "Now, the left breast...♥♥" Sana: "The left breast will retaliate...♡♡" 　It doesn't stop. The act of pouring breast milk into each other's breasts is repeated endlessly between the two of them. If there had been some kind of equilibrium, the breast milk pouring would have ended. However, the mammary glands and lobules of both breasts never admit defeat, and because they never compromise, the breast milk pushing and exchanging between the two of them never ends. 　What's more, the amount of breast milk is gradually increasing. This is probably only natural. The stimulation of having another person's breast milk poured into their mammary glands and lobules has increased the amount of breast milk they produce. It's not clear whether this is to clean their own mammary glands or whether it's an attack to drown the mammary lobules of the other person who is cheekily attacking them from the other side of the nipple. 　Anyway, Rina's mammary glands and Sana's mammary glands are competing with each other, competing with each other's breast milk production. The two girls' original J-cup breasts have become enlarged in this battle, and are now the size of K-cups, or perhaps even L-cups. 　For Rina and Sana, who are forced to share a single sweatshirt and are feeling the squeeze, the growth of their breasts forces them to press against each other even more, and in turn this leads to the breasts sinking into each other like they are in a battle for territory. 　The opposing lobes of the mammary glands in their breasts release breast milk at each other, and from the outside of their breasts, the lobes of the mammary glands press against each other. The lobes of both sides of the mammary glands do not give an inch. They are fighting each other with all their might, out of fear that if they show even the slightest opening, they will be destroyed. However, even the strength of the lobes of the mammary glands is the same in the bodies of the twins Rina and Sana. 　The battle between the mammary glands has no end in sight, and the two have been forced to fight each other in what seems like an eternal struggle. Rina: "Unngh♥ I'm excreting everything, all over Sana, and she's excreting everything all over me♥♥" Sana: "Unaa♥ I'm excreting into Rina all over, and I'm being excreted into♥♥" Rina: "I peed into Sana, but it got mixed with my pee♥ We're both going to mix our pee in each other's bladders♥♥♥♥" Sana: "Even though I pooped in Rina, it got mixed up with Sana's poop♡ We're going to mix our poop in each other's rectums♡♡♡♡" Rina: "I shot my milk into Sana's left breast, but she shot her milk into my right breast♥♥" Sana: "I shot my milk into Rina's left breast, but she shot her milk into my right breast♡♡" Rina and Sana: "This is like having sex with a bladder and a bladder and having a creampie♥♥♥♥" Rina and Sana: "This is like having sex with a rectum and a rectum and having a creampie♥♥♥♥" Rina and Sana: "This is like having sex with a mammary gland and a mammary gland and having a creampie♥♥♥♥" Rina and Sana: "This is like the worst kind of dirty exchange creampie sex between toilet women and toilet women♥♡♥♡. It's the worst♥♡. It's the worst♥♡♥♡." Rina: "All I want is for Sana to become my own personal toilet woman♥♥♥♥." Sana: "All I want is for Rina to become my own personal toilet girl♥♥♥♥" Rina and Sana: "We're going to thoroughly turn that cheeky toilet girl who's rebelling against us into a toilet girl♥♥♥♥. We'll make her pay for her insolence♥♥♥♥." 　They excreted urine, feces and breast milk all at once, and at the same time, the act of excreting and being excreted by their own personal toilet girls was repeated endlessly afterwards, and when they reached their limit, they rushed into the same toilet and released everything at once. The two of them, who had just had the most abnormal and worst excretion, were exhausted and fell asleep after a quick shower. 　Tomorrow, they will repeat the same "excretion". Thinking about this, they went to bed close together, their crotches wet for no reason. After this bizarre act... an act that was neither excretion nor intercourse for the two of them, Rina and Sana continued to live their lives excreting while also excreting for each other. 　There is no way they can do this kind of thing with anyone else. And they can't forget about this intense act either. Rina and Sana are like they've stolen each other's lives. Their relationship, like a mutual training session where they use each other as toilets, continues endlessly.
