"I found this strange shop with supposedly magical knick-knacks...I guess that's where you got your udder?"
Sally nodded.
"Well, I grabbed these. They looked real enough, so I figured you could add them to your costume." Colin reached into a shopping bag he had brought with him and pulled out white and black-spotted latex gloves. These gloves, however, didn't end in fingers. Each ended in a hard plastic hoof. There were two for her hands and two for her feet.
"Nice," Sally said. "But right now I think I'd better get out of this tub." She carefully stood up, nearly slipping on the milk. The weight of her udder was also hindering her efforts. Colin pulled the plug out of the drain to let the milk filter out, then wet a hand towel to wipe off Sally's milk-soaked legs.
"That really is a nice-looking udder," Colin said, fascinated. He poked it and Sally shrieked.
"PLEASE don't do that! I can really feel it."
"Oh...sorry," Colin said, flabbergasted. He didn't expect the items from that store to actually be magical, but was strangely glad to discover they were.
After Sally was out of the tub and dry, Colin picked up the hoof gloves. "You want to try them on?"
"What if they get stuck like my udder did?" Sally feared.
Colin pulled a tag off one of the gloves and read its small print. "It just says they're like normal gloves. You can peel them off any time."
"Okay...I guess," Sally said. Anything to distract her from her udder, which was starting to feel stretched again now that it was hanging free. Its bulk pushed up her top quite a bit, and her underwear was being strained underneath the large orb.
Colin removed the tags from the gloves as Sally sat on the toilet cover. He slipped on the hind hooves one at a time, pulling the latex tightly up her ankle. The spotted gloves reached almost up to her knees.
"Try to stand," he said. Sally stood up, holding onto Colin for support. She clopped her "hooves" on the linoleum, finding that the structure of the gloves caused her to stand on her tip-toes inside the plastic hoof base.
"It's kind of hard to balance," she said. "I don't think these were made to stand in like this." Colin helped her sit back down.
"Guess you need all four of them," he mused, thinking the costume's true purpose was to make the wearer feel as close to being a real cow as possible. That would make things rather awkward at the party. However...here in the apartment, the concept of his girlfriend walking on all fours excited him. "Try the hands too, just to try it out."
Sally picked up one of the remaining hoof gloves and pulled it over her left hand. Her fingers slipped into a groove inside the plastic hoof much like her toes did. The latex stretched up her arm and ended just before her elbows. She moved her hands to grab the other glove, but realized with her hand in one of them, she couldn't put it on.
"Duh," she laughed to herself. Colin smiled and helped her slip into the right hand glove, completing the arrangement. Sally slipped off her seat and pushed her upper body forward, landing her hooves on the floor with loud plastic claps. She seemed to be all right standing on her hands and feet, though her human proportions weren't very fit for such a position. Her arms were too short to level off her body, but she managed all right as she tested a walk down the hallway.
Colin watched his girlfriend clamber away, showing her round ass to him which was barely obscured by her underwear. He watched her udder sway between her legs as she hobbled down the hall, and inside him strange urges developed that he found hard to ignore.
"Okay, this works fine...I guess," Sally said once she had reached the main room of the apartment. "Dunno if I should wear the hind hooves to the party though. It'd be weird talking up to everyone else like this. Want to help me out of these things?"
