Cindy and David both worked at PetroChem Inc., a large industrial chemical processing plant. While Cindy was just a secretary, David was a high-level researcher who worked directly with the chemicals. Cindy and David had dated off and on, but never really had anything major going. David was about 6'2", average-to-handsome face, and athletic build. Cindy was a vision of loveliness: 5'9", long flowing blond hair, deep blue eyes, perfect ass and legs, but for one problem; she had an incredibly flat chest. She was very self-conscious about it, too. A lot of people seemed to always stare at her, or so she thought. She was paranoid about it too.
David was working late one night when everyone was gone. This was his favorite time to work, as he could get away with things he should not be doing.
"One of these nights, I'll get this formula to work!" he said like a mad scientist. He had been trying for months to perfect a breast-enlargement formula, to help Cindy, because despite their lack of a major relationship, he really liked her. He went back to work on his formula until early morning.
Things went on like this for another 2-3 months until late one Friday night, the words: "YES!!! I've done it!!" echoed through the empty hallways of PetroChem Inc.
"Finally! I have completed my formula! I've got to call Cindy right away!" He poured the formula into a 2 liter bottle he had kept in his bag to store it. He ran to the parking lot and jumped into his car and drove toward Cindy's house.
Cindy awoke to the ringing of the phone.
"Hello?? Who is this? Do you have any idea what time it is?"
"Cindy, it's David, I'm on my cell phone. Yes I know what time it is. Get yourself awake, I'm coming by with a surprise."
Before Cindy could reply, David had hung up. Groggily, she got out of bed, and took off her nightgown, and pulled on a pair of panties, and her nearest bra. She then bumbled into the closet and grabbed a t-shirt and a pair of jeans.
David pulled into Cindy's driveway and jumped out of the car. He rang the doorbell. A very sleepy Cindy answered.
"This had better be some damn good surprise," she grumbled.
"Oh you bet it is!" said David excitedly. They went into her house and sat down on the couch.
"Now, Cindy, I know how you are about your breasts..." he trailed off as she gave him a glare of pure evil.
"Now wait, hold on a sec..I can fix that! That's my surprise!"
"What?? What are you gonna do? Tell me to get implants? I can't afford those and you know it! I should throw you out of here!"
"No! I can do it with this!" he held up his bottle of formula. "It's a formula that enlarges breasts! I've been working on it for months!"
"You're kidding."
"No, I'm not! I did this for you. Will you take it?"
"Well, even though I think you're lying, what could it hurt to humor you?"
"That's the spirit! Go lay down on your bed and remove your shirt. Don't worry, it's not like I haven't seen them before. I'll go prepare the proper dose."
"All right." Cindy went into her bedroom.
As David walked into the kitchen, and began looking for a measuring cup, a nasty thought escaped and ran through his mind.
"What if I gave her more than the proper dose," he thought, "she'd never know until it was too late..."
He wrestled back and forth with this idea, until the idea won. Without even measuring, He just dumped a large amount of formula into a very large glass. He smiled as he walked back to her room.
He handed her the glass. "Just drink the entire glass. The effects should be quick."
She took the glass and gulped it down.
About 10 minutes passed with no apparent effect.
"Well, thanks for getting my hopes up, David." Just as she said this she felt a strange tingling in her breasts. She looked down and saw they were beginning to inflate.
"Omigod!!! It's actually working!" she said. David did nothing but smile. Cindy's breasts continued to balloon until they were straining her bra. Cindy quickly unclasped and removed it. The growth began to speed up now and soon her breasts were a very plump DD.
"How big am I going to get??" She asked.
"Not quite sure," said David.
"Not quite sure?? Not quite sure?? Grrrr. If this didn't feel so good I'd kick your ass."
The growth began to increase in speed yet again. Cindy's ever-inflating boobs were now beachball-sized. All Cindy could do was giggle in pleasure. Her boobs had now ballooned to the size of large bean bags. When she was fully on her back all you could see was massive creamy tit flesh.
"David, am I done? Can this be reversed? I think I'm a little too big."
"Here, this is the reversal formula." He handed her the 2-liter that contained the remainder of the growth serum. She downed it without thinking.
Bigger and bigger her mams surged, but no matter how big they got, they remained perfectly shaped, round and no stretch marks. Her boobs had grown so big she could no longer reach or see around them except through her cavernous cleavage.
As they grew, passion built in her, and she yelled for David to suck her tits.
"David, they're so big!! I want them bigger! Suck my huge tits!!" He gladly stripped and obliged her. As he was sucking her nipples, she began struggling to remove her jeans.
"Here, I'll help you with those," and David helped her remove her jeans.
"Fuck me!" she screamed.
David just grinned.
After a long night of furious sex, Cindy and David awoke the next morning.
Cindy was shocked at first at her huge tits, but soon the shock subsided and became horniness.
"David! Fuck me!"
And they did.................................................................
