Colin didn't answer Sally at first. He looked at her from the far end of the hall, standing shakily on her four limbs. Her udder sagged like a water balloon between her legs.
"Well?" she asked, finally sitting on the floor to the relief of her strained legs. She scraped one fore-hoof against the other in a feeble attempt to shove off the gloves. "These are on here tight. I can't do it without hands."
Colin's gaze wandered over to the white gun Sally said she had used to fill her udder. An idea struck his mind, and he picked it up. "Why don't we do a little bit of experimenting?" he said calmly.
"What do you mean?" Sally asked. She watched as Colin approached her and squatted down to meet her eye-level.
"I mean," he smiled, "Let's find out how pleasurable this thing can really get." He quickly grabbed one of her rubber teats and pulled, sending a jet of milk shooting out. It splashed against his leg and made dabs on the wood floor, but he paid it no mind. He was too busy watching his girlfriend moan in pleasure as he continued to let her inner juices loose.
Sally tried to push away from him, but the thrust of her hooves was weakened by the milking. She thrashed her legs around the floor, but that only made Colin pull harder, granting more sweet release for Sally's tight milk sack. She moaned louder, unable to resist the pleasurable urges long enough to pull herself away from him.
Eventually, the udder was nearly drained of liquid, but that didn't stop Colin. Sally's eyes widened in horror as she watched her boyfriend's twisted smile reappear. He held up the white gun and held her udder firmly while he inserted its four nozzles into her teats. "Stop, Colin! Please...pleaaaAAAH!" More liquid shot into the udder, filling it up quickly and increasing the tightness that she had felt before. He didn't stop when it was full, however. He kept his finger pressed on the trigger as the rubber chamber stretched further, nearly reaching its limit. The "skin" was so tight, Sally winced and stammered as her plastic hooves vainly rubbed the tender bulge, now almost the size of a beach ball. Colin removed the gun from her dripping teats and stepped back to watch her writhe on the floor, curled up around her udder and clutching it with her hooves. Milk was slowly seeping from the erect teats.
"I wonder if I can use this in other places...," he mused to himself. Sally was so blinded by the sensations coming from her swollen udder that she didn't notice Colin leaning over her crumpled body until it was too late. He ripped off her delicate top and bra. He stabbed the flesh around her left nipple with the four-pronged gun and squeezed the trigger.
The inside of her chest felt icy cold at first, then started to feel much like her udder as her left breast swelled. It filled with the magical milk and grew over twice its size. Her skin stretched painfully. When he was done, Colin pulled the gun from her breast. The nozzles didn't let go without a fight, however, as they pulled her skin out several inches before giving up. She was left with four nubs that oozed white milk just like teats. He did the same to her right breast, and Sally was helpless to stop him.
Every second the strain of holding in so much milk increased. Her huge breasts pushed against each other and her udder. She needed release, and she needed it before her body exploded in a shower of blood, guts and milk. Her fingerless hooves could never do the job. She tried desperately to force a plea out of her mouth, but all that she could manage was a shrill moan.
"I know what you want," Colin said. "And I'm more than happy to give it to you...but first..."
