Deryck and his wife had finally gotten pregnant. That is to say that Deryck’s wife got pregnant. He always thought it was funny that couples said that they were pregnant together. Regardless, they were ecstatic to be bringing a child into the world together. Months went by, and Deryck’s wife began to develop a belly. As she reached the second trimester, her boobs began to fill with milk. Naturally, she went and bought a pump to save the milk for when the baby arrived. She would pump as needed and had begun to save up a good little stash.

Deryck had always been curious about breast pumps though. It seemed like such an odd thing to do. It was as if during and after pregnancy, humans just turned into cows for a bit. One day, while the wife was at a pregnancy yoga class, Deryck began to inspect the breast pump. He had never really looked all that closely at it, but he could see now that it was actually pretty fancy. She must have spent quite a bit of money on it. The pump unit had all sorts of buttons, dials, and settings that didn't seem terribly self-explanatory. Deryck's curiosity had been fully piqued though. He popped off his shirt and placed one of the breast pump cups over his nipple. 

Deryck pushed a small button that he assumed was the power button, and the small LED display on the pump sprang to life. It read: error, only one cup engaged. Deryck placed the other cup on his opposing nipple. The display changed and read: scanning. It stayed on this screen for a while, and Deryck wondered what it could possibly be scanning. Then the display changed again to say: Insufficient production… Adjusting output. As soon as it displayed this, the pump shot into action and began tugging on Deryck’s nipples aggressively. It was relatively uncomfortable, and Deryck had decided he had had enough. He tried to pry the suction cups off, but they simply wouldn't budge. The suction was far too strong.

Deryck tried to power down the pump, only to be met with display text reading: Unit cannot be powered down during adjustments. This was around when the “adjustments” actually started. With each tug of the pump, Deryck's chest began to inflate for lack of a better word. It was as if the pump was pushing instead of pulling as more and more flesh began to mound under the cups. Deryck grabbed at one in a panic and found that it felt full and swollen. The pump’s suction intensified, and jets of milk began to shoot from Deryck's now growing tits. Spinning around to face the mirror, Deryck found that it had been working on more than just his chest. His whole face had changed to resemble a female version of his former self.

Deryck leaned over, placing both hands on the countertop as the machine continued to do its duty. The milking, despite its intensity, was actually beginning to feel pretty good. Deryck moaned out loud in a voice much higher than the one he remembered having as even more milk was extracted from his steadily growing breasts. Finally, the machine slowed and came to a stop, leaving Deryck panting and horny. The two bottles that were attached to the cups were full. Deryck wasn’t done though. He wanted the pump to keep going, keep milking, keep pleasuring. His tits were still so full of milk. Deryck removed the two full bottles and inserted fresh empty ones. He began to put the cups back on when the bathroom door swung open, and his wife stepped in. He hadn’t heard her come home over the noise of the pump. He had been caught, but he wasn’t going to let that stop him.
