*Author's Note: You Might want to read "A Special Treat" 1-3 just to get up to speed. Or don't, if you really don't want to. It's not like I'm going to make you.
Racing winds whipped through Darcie's long brunette hair. She turned to see Heather dressed in her shorts and flip flops, but with a larger version of her white halter top with her enormous boobs popping out of the sides. Up front, Joyce had an unbuttoned white lab coat covering what she could of her voluptuous breasts. The wind tossed the fabric around and around. Sometimes her nipples would be flashed to anyone who happened to look in her direction.
The doctor turned around. "So, how do you girls like my new car," she yelled behind her through the roar of the wind.
"I've always been a convertible girl," Heather yelled back.
"Yeah, it's cool. Now, you'd better turn up here to avoid traffic," Darcie leaned over the front passenger seat. She could feel the upper hem of her spaghetti strapped top peel back slightly over the tops of her areolas.
"Please darling, I know how to get there. You know, they do carry smaller sizes than E cups, right? In fact, they're probably the best bras around by far."
"I know, but they can be expensive!" Darcie sat back down in her seat.
"Well, you get what you pay for." Joyce turned her review mirror to focus on Darcie. She could see the brunette's light brown areolas peeking just above her new shirt. "Darcie, I believe you're popping out of your shirt again."
Without looking down, Darcie fixed her shirt. "I swear, I don't fucking care anymore! These boobs are starting to become more of a pain in the ass than they're worth."
"Come on, Darc," Heather leaned over and nudged her friend. "Don't they feel great? Don't you feel sexy?"
"Yeah, but it's annoying sometimes. I like my big titties, but not when they're always in the way," Darcie yelled back and could hear herself a little more clearly. The convertible slowed down and pulled into an empty parking space near the store front. The doctor stepped out of the car.
"I told you I knew how to get here, and with an hour to spare before they close. Impeccable timing if I might say so," Joyce strutted around and pulled the latch to bring her seat forward. Both girls stepped out of the car and looked at the brightly lit sign in the window. It read "THE BRA-GAIN CENTER."
"How appropriate since we've gained quite a bit in our busts..."
"Come on!" Heather squealed with anticipation as she skipped past Darcie and Joyce. "I can't wait to find out how big I am!"
"I'm positive it will be quite interesting," Joyce retorted with a bright smile. The wind whipped the doctor's lab coat around to expose her swollen left breast. She leisurely brought her hand down and caught the hem to pull it over herself.
"Yeah, it's going to be real interesting when I see the price tag of that bra. You know, maybe I won't wear one until it wears off," Darcie pressed on following the doctor.
"Nonsense, sweetheart. If you go without support until your body rids itself of the drug, you'll be ready to cut those girls off in a week because of how heavy they'll feel. Sure, they don't feel heavy now. That's just because your body's trying to get used to the change, but you'll eventually feel it."
"I feel it right now, Joyce. My breasts are so sensitive that my nipples rubbing against the fabric of this shirt are making me wet. Every time I take a step, they jiggle more and more and it's all I can do to not tear my clothes off and do myself right here in the parking lot!" Darcie stopped and Joyce turned to console her. Heather kept joyfully skipping towards the entrance.
"Darcie, I understand how you feel. Yes, this is a blessing and a curse but just try to look at the situation in the brightest light that's possible," the doctor brought her lips up to Darcie's for a gentle embrace. "I'm sure you'll feel a renewed surge in your self confidence once you find out how big you are. Besides, your boyfriend will love it."
"Yeah," Darcie smirked. "That's all I need right now. He'll be planting those pills in everything I eat until the day he dies."
"Come on, Silly. Let's get you measured." Dr. Smothers snaked her hand around Darcie's arm, unintentionally pressing the back of her hand against the side of Darcie's right breast. She led the brunette to the shop where Heather had already bounded into the double glass doors.
Upon their entrance into the shop, Darcie and Joyce noticed Heather talking with a sultry woman with sexy features and shimmering, raven black hair. The woman's dark red lips naturally formed a sexy pout that seemed to be her best facial feature aside from her dark eyes. The redhead had her chest hefted above the counter and exposed as much cleavage to the seated woman as if she were seducing her way out of a speeding ticket.
"...You'll be able to tell that they need bras too... OWW!" Heather turned to see Dr. Smothers behind her. Quickly she rubbed her behind and figured the pain she'd felt there was from her physician pinching her butt. "Doesn't that go against the Hippocratic Oath, Dr. Smothers?" The redhead glared back at Joyce, but suddenly noticed an older woman who seemed to be in her late forties come through the curtain that led to the stock room.
"Hello, ladies. Maybe I can assist you in finding something," the woman asked without missing beat.
"Yeah, we really need..." Heather started to speak but Joyce slightly nudged her aside.
"Ma'am, my friends and I are in dire need of new undergarments and we were wondering if there was a way to get precisely measured to find out what size we require."
The older woman looked the three very busty women up and down and smiled widely. "I think we can accommodate your needs. My name's Margie and you'll just follow me..." Margie turned to walk towards the dressing rooms in the very posh boutique. Just before she began to walk away, she turned to the raven-haired clerk. "If anyone needs me, tell them I'm busy ordering, okay?"
"Uh, yeah. Sure." The clerk nodded. Just as the four women trotted away, Heather turned back to her new friend and flashed her a seductive smile.
"I'll talk to you when we're done, Denise."
"See you in a minute, Heather." Denise was a bit hesitant to return the erotic gesture, but did so eventually. She could help but admire the way Heather's breasts jiggled as they stuck out past her sides. She'd never seen anyone's boobs do that from behind. Now, she had just witness three hot women who had the same trait just walk past her. Denise could feel her clit throbbing from the sight. She squeezed her thighs and bit her lip at the thought of experimenting with that voluptuous redhead.
Once they had entered the sales floor of the store, Margie turned to the three women and pointed towards a doorway with draped red velvety curtains. "If you three will go to the fitting rooms, I'll be there in a moment."
Joyce led the way, with Darcie and Heather in tow. Darcie felt her sexual frustration subsiding on her way to the fitting rooms. She knew she was going to be alone for a moment with Heather and Dr. Smothers. Her mind was anticipating a brief tryst with the two busty ladies before Margie came in to do her job. The brunette droned on behind Joyce and remembered how blissful it felt to have Dr. Smothers' skilled fingers teasing and massaging her sensitive breast flesh. Part of her was still in reality because she could sense Heather's perkiness as she walked. Darcie could tell that her excitement was well contained as much as she could possibly stand, but Heather exuded her feelings as well. Just at that thought, Darcie's brown nipples hardened at the thought of going at it again with Heather. Her friend was an intense kisser like her boyfriend. Then, she remembered how Dr. Smothers liked to tease and linger just within reach, her lips brushing just enough to make contact. The voluptuous brunette's pussy moistened more and more to where Darcie could feel the dampness in her crotch as she took each step.
"Darcie," a familiar voice called out. The brunette snapped back to reality and saw two good friends who were students at the same college she and Heather attended. Nelly, a voluptuous ginger haired cutie with a 38D sized bust; and Carmen, another of Darcie's very close friends with shoulder length black hair, sheet white flesh and titties that had to be stuffed into a 42G cup bra were browsing along some of the clearance racks near the entrance to the fitting rooms.
"Hey Darcie, what's happening," Carmen said stepping to the hot brunette. "What's up, Heather? What're you two girls doing here?"
"Oh Carmen, I've got to tell you about the coolest shit! It's so awesome..." Darcie turned and punched her redheaded friend in the arm. The force of her blow caused her tits to spring free from her new spaghetti strapped top. Carmen and Nelly stood in awe of Darcie's jiggling mams. The brunette quickly brought her hands down once she realized what had happened in a vain attempt to cover her bulging beauties. Nelly and Carmen both stepped in closer to get a better look. Both of Darcie's busty friends amazed at how big their busty friend had gotten, well... bustier.
"What in the world happened, Darcie?" Nelly was reaching her hand out to touch Darcie's olive-skinned boulders. Then, Joyce came to the fold with her lab coat whisking around her.
"Just a growth spurt, ladies. I'm Heather's physician and I'm here to assist them on finding a suitable bra for their particular situation."
"Yeah, just wait till the next party we have," Heather chimed in. The redhead pulled the top hem of her shirt down and exposed her massive porcelain breasts. "I'm sure the girls will get a load of me!" Margie strolled up to the five women with her measuring tape draped around her neck and dangling down to rest on her ample bosom. Her eyes almost bulged out of her sockets at the sight of Heather jiggling her huge tits for her awestruck friends.
