Constantly Growing

Professor Johnson looked from Burroughs to you and gave a small smirk. The look of subtle approval sent a satisfied shock through you. Immediately you felt your nipples harden and threaten to pierce your overly strained tank top. As your secret benefactor turned back towards Burroughs, you felt the pressure behind your nipples peak before beads of sweet milk began to pool in the fabric and spill down your shirt. You stifled the smallest of moans as they bickered back and forth.

"I could understand how her being in a trial two days in a row could be a clerical error, but four? She's so full of experimental drugs right now that her clothes can't even contain her!" He didn't know that you had bribed Johnson to have access to these trials. Even better, neither of them knew that starting on the second day, you began to buy the drugs from several of the other trial participants, quickly realizing that they were only there for the money not the actual effects of the drug. Those extra drugs were now safely in your purse hanging off the chair.

It was advertised as a breast enhancement lactation drug. Side effects include: increased fertility, increased libido, increased appetite, increased sensitivity, dominant tendencies, muscle growth, etc...

As Johnson tried to explain away how you happened to be in all four trials, the drugs from that day began to kick in. Waves of pleasure began to wash over you as your milk fully let down. Neither was looking at you as you felt your fourth growth spurt in as many days take hold.

A loud creak in the chair followed by a massive tearing noise in your top instantly demanded the focus of both administrators. Their jaws dropped as your breasts were finally freed, openly spraying steady streams of milk across the room.

"Oops." You muttered, standing up and taking the chair with you. Shaking your ass free caused it to break apart, your skirt falling away with it. You were now left in a spilt top and strained, soaked panties. "I think your drug works really well." You said, hefting your new udders to test their size and sensitivity. You cooed in pleasure as they jiggled endlessly in your hands before moving to your nipples to express torrents of milk. "I feel so huge. I feel so sexy. I feel so good." You moaned, temporarily lost in your own pleasure. Johnson reached across the desk to grab his milk-splattered clipboard and began to take notes. 'Subject is in a state of euphoria. Subject has grown over a foot and several cup sizes. Subject is a giant sexy milk machine.' He only thought that last part, but he wasn't wrong.

"We need to get her to a hospital!" Burroughs said, trying to take control of the situation.

"No, I think I want to see where this goes." Johnson countered. "It's valuable data. Imagine if this drug makes it to market. Anyone would be able to take a dose this high."

His words pulled you from your stupor. You weren't just anyone. You didn't want anyone to be able to have what you had. "You make several good points professor. Except. No one else should be able to take a dose this high. I will give you some more data to work with though." Reaching down into your purse, you pulled out the bag of drugs from the other participants and emptied it into your mouth before either administrator could comprehend what was happening. You grinned and stuck out your tongue after swallowing them all like you needed to prove that you actually did it.

"Holy shit," Johnson blurted out. "You actually did it."

"You boys might want to run." You teased, already feeling the pills starting to work their magic. You could feel your heartbeat in your nipples as they heated up, the flow of milk only increasing with each cup size. Your feeble panties snapped away as another wave of growth surged through you. Naked and glowing, you reveled in your own enormity as your tits started to envelop the room. The exit was behind you. The two man were now trapped as your breasts began to press into them, coating them with your milk. They pushed and fought against your massive mammeries, but that only fueled your arousal.

"That's it, knead my giant fucking tits. That feels so good! You might as well help me out while you're over there, why not latch on? Have a drink? I'm producing more than enough for everyone!" It was true. The whole floor was now soaked and the room was full of the sweet scent of your milk and arousal. Suddenly you felt it, two needy mouths tugging and sucking on your impossibly sensitive nipples. An intense orgasm immediately wracking through you. As you threw your head back, you bumped the ceiling. You were running out of room. Post climax weakness filling your legs, you fell to your knees before collapsing in the cool pool of your own milk. Your last conscious thought was that you hoped you were still getting paid for all four days of the trial since new clothes would be really expensive. And you'd need an industrial sized pump. And a bigger place to live.
