You seemed to drift back into bliss as the machine drains your new udder-scrotum and cock, pulling out pint after pint of cum. Slowly, your udder begins to shrink back down, just slightly, enough that you can sit comfortably. You didn't want to be some half-human half-cow.. thing.. and started thinking through your options. Aster seemed off in his own little world, tugging on his restraints, shifting about to see how much give he had. He was planning something, "What you thinking?"
Aster just shook his head and went back to checking his restraints. No.. straining them. He was trying to get them to snap. Though he went still a moment before you heard it yourself, the clop of hooves coming back down the hall.
Bessie came into the room, looking between her two prizes, holding a bottle of something in her hand. Her gaze settled on you. "Well, let's see how this little concoction I just whipped up works. Seeing you there with all those pumps gave me the most wonderful idea." She practically giggles as she steps closer to you, uncorking the bottle with her thumb. She pinches your nose and shoves the bottle in your mouth, forcing you to swallow or choke. The mixture tastes milky and creamy, but warm, and feels like it coats the inside of your chest.
Once you've swallowed it all, she pulls the bottle from your mouth and steps back, an artist surveying her work. A tingling spread through your chest and you looked down just in time to see your nipples swelling. "Oh god, no!" You can't help but cry out. They were growing plump as your areolas grew to almost two inches across. Then your chest started to puff up. Was she giving you breasts?!
No.. the shape wasn't right, they weren't the soft, laden globes of breasts, your chest looked firm. It looked like you were growing a pair of large pectorals.
Bessie was tapping her lips. "Interesting, adding the protein complex seems to have made the mammary tissue pad itself with muscle rather than fat.." So they were breasts.. but muscle breasts? Your chest looked ridiculously over-muscled compared to the rest of you, though looking yourself over again, the concoction seemed to have added a little bit of muscle everywhere. You had a bit of tone, but it was still lean, except for your chest that looked like it came off a body builder, well, other than the female sized nipples.
Milky white droplets formed on the tips of your plump, over-sized nipples. Bessie reached out to give them a little pinch. The feel of your nipples squirting milk was a strange sensation, but not unpleasant. "I'll have to run tests on the properties of this milk.. But imagine the possibilities." She flicked a drop of the milk from your nipple with a finger, bringing it up to her nose for a sniff. "Let's get you hooked up and start harvesting. Then I'll come back with more of that mix for dear Aster, here."
