【TF娘】蒲生まみの受難#3

毎朝の搾乳に嫌気がさしていたマミは、自動搾乳機という機械の存在を知る。動画サイトで実際に使用されている映像を見ると、確かに便利そうな機械だ。しかしそれ以上にマミの興味を引いたのは機械で搾乳される牛の鳴き声が非常に艶めかしい、人間で言う喘ぎ声に聞こえたことだ。動画にくぎ付けになり口からは画面の向こうの牛と同じ呻き声が漏れる。それから通販サイトで搾乳機を購入するまではあっという間だった。

届いたダンボールを開け、実際の搾乳機を目の当たりにしたマミは、それが明らかに人間用ではないことに苦笑いした。着ていたシャツをたくし上げ、あらわになった乳房は牛化の弊害なのか乳首が親指以上に肥大化している。ホースの先の冷たいカップを乳房に押し当てスイッチを入れると、搾乳機は唸りをあげてマミの乳首を吸い始めた。

その瞬間、快感が全身を駆け巡り思わず声をあげる。他者に乳首をいじられるという初めての感覚に頭の中でパチパチと電流が流れるような気がした。快感で震えるたびに体はより搾乳に適した姿へと変化し体重が増えて膝立ちを続けることが難しくなる。床に手をつき四つん這いになり、尻尾を高ぶる感情を表現するように大きく持ち上げ、カップがついていない腹の下の複乳は体と床の間で潰されブシュブシュと白い水たまりを作っている。

今日も牛の力強い鳴き声が住宅街に響き渡る。だが誰もそれが人間の女性のものだとは思っていない。

Mami, who was fed up with milking her cows every morning, learned about a machine called an automatic milking machine. Watching a video of the machine in use on a video site, it certainly looked like a convenient machine. However, what caught Mami's attention even more was that the cows milking with the machine made a very sexy sound, which sounded like a human's gasp. She was transfixed by the video, and her mouth was moaning just like the cows on the other side of the screen. It wasn't long before I bought a milking machine from a mail-order website.

When Mami opened the cardboard box she received and saw the actual milking machine, she laughed at the fact that it was clearly not designed for human use. She pulled up her shirt to reveal her udders, the nipples of which had grown larger than her thumbs, probably due to the effects of her transformation into a cow. He pressed the cold cup at the end of the hose against her udder and flipped the switch, and the milking machine roared to life and began sucking on Mami's nipples.

At that moment, pleasure ran through her entire body, and Mami involuntarily screamed. She felt an electric current crackle through her head as she felt for the first time the sensation of having her nipples tweaked by another person. With each shudder of pleasure, Mami's body changes into a more milking-friendly shape, and her weight increases, making it difficult for her to remain on her knees. She was on all fours with her hands on the floor, her tail lifted up to express her heightened emotions, and her uncupped, under-belly udder were crushed between her body and the floor, creating a white puddle.

Today, the powerful cry of a female cow echoes through the residential area. But no one believes it belongs to a human.
