Author Note: Just a slight bit of comedy. A potential NSFW bit of naughtiness with inflating boobs, double entendres and implied sexual behaviors.

Hermione was frustrated. She was back for her seventh year after the war and confused by which boy she really felt the strongest feelings for. She had gone through hell with Harry, Ron and Neville so loved and cared about all three of them equally so decided to let her sexual repression be the deciding factor. Only she wasn't sure how to decide which boy turned her on the most without being with each of them. She wanted to make sure before she went that far.

With a bit of research and inspiration she developed a potion that would allow her to have a physical and visual confirmation of which boy got her so excited that she had been repressing.

Brewing the potion she acquired some hairs from each of the boys. Shaking one of Ron's hair into the vial she watched as it turned a dull dark pink. Not excited by the appearance she swallowed the dull tasting potion. A moment later her breasts deflated completely, her nipples shrinking and looking like she was nine years old again. Casting finite she felt relieved when the girls were back to their normal handfuls.

Dropping Neville's hair into it she swallowed the magenta fluid that tasted slightly like mangos. She grunted as she was suddenly sporting twin honeydew melons. She was pushing the limits of her bra and blouse with the girls and was quite impressed. Casting a finite she heaved a sigh of relief as she returned to her handfuls. Although she did rub them a bit as they were slightly achy.

Putting Harry's hair into the potion she gasped as it turned scintillating pink. She drank it and screamed as she felt her clothes burst from the sudden explosive growth of her bosom. She was knocked off of her feet by how suddenly her center of gravity changed. She still held her wand and called for Harry to come help with a patronus.

Struggling to her feet she leaned against a desk as she tried to reach the dusky taut nubbins at the top of the mammoth mounds projecting from her now. She could just barely reach them and realized that Harry had definitely won the sexual energy repression contest. She must have been repressing her attraction for him for a very long time.

Harry burst through the door so quickly she was wondering if he had managed to bypass the anti-apparate wards. "Hermione! What's wrong? Are you okay?" He said looking around then freezing his stare on her expanded breasts.

"I uh. Well I developed a potion that would reveal how sexually attracted and repressed I am towards a person." She said with a grin slapping the side of one of the warm meat balloons with their taught tips pointing directly at him thanks to a levitation charm she had applied.

"Oh. Sexually attracted eh? I guess I'll go call Ron."

"Please don't. When I took the one keyed to him I shrunk smaller than I was when I was nine. Not fun." She said.

"Oh then who are these for?" Harry dared to ask as he stepped closer. His eyes and something else growing larger as she did nothing to conceal them.

"Well to paraphrase Hemingway my dear, Ask not for whom the boobs grow, they grow for thee." she said with a coy grin.

"For me?" he asked eagerly.

Reaching down to slide her skirt to the floor she said, "All for you."

Harry's clothes seemed to melt off of his body they had been removed so quickly. Kiss rained across each other. It would have required a physics equation to know who had jumped whom first but the magical energy built up in the lab as their passions joined, then built. Years of repressed feelings for each other released in an explosion of passion that spread out from the lab in waves.

In the greenhouses every plant sprung forth in a burst of fecund glory. The elves burst into the great hall with a Busby Berkeley dance routine. An old man leapt from his deathbed to make love to his wife once more. It was a joining most devoutly to be wished.

Laying in post coital bliss Harry panted, "Wow. How do you feel Hermione?"

Reaching up to rub her now returned handful bosom she sighed, "Not at all repressed."

"Good. I think I'll help keep you that way." He said with a grin.

Rolling him over onto his back she kissed his nose, "I certainly hope so." She then kissed someplace else with a much stiffer response.

…...

Several days later Head Boy Harry Potter was walking much better. Sitting in his common room he heard a knock at the door and shuffled over. Opening it he found a highly inflated Luna leaning against the door frame. She looked like she was trying to smuggle rather moderate sized dirigibles under her shirt.

"Luna? Did you take some of Hermione's repression revealing potion?" he asked licking his lips. Especially when he noticed the tips of each sweater zeppelin were the size of lemons themselves.

"Oh yes. Ginny demanded Hermione let us as she wanted to prove she was the most repressed girl for you around." Luna explained with a sigh that started by her chest wall and took several seconds to propagate to the tips.

Harry caught his breath as it tried to leave his body and said, "Oh. So uh. Where's Ginny?"

Luna shrugged which caused motions that entire math departments could write a doctoral thesis on. "I suppose the hospital wing. Her breasts inverted."

"INVERTED?" Harry shuddered.

"Yes Apparently there is a rather large difference between being sexually obsessed with someone and being sexually repressed for them." Luna said as she began to enter the room. A moment after her breasts had already done so.

"Oh. Well uh. I suppose you're going to wait here until Hermione can come and restore you?"

Sliding her shirt off Luna shook her head, "No. She gave me permission to have you help me not be repressed."

"Oh. I see." Harry said nodding as he shut the door.

Smiling warmly Luna turned and headed for his bedroom, "No you have seen yet, although when you get to the bedroom you will see."

Harry smiled as she slid her skirt down revealing her namesake anatomy was just as lovely as the rest of her.

"Oh the things you shall see Harry my boy!" Harry laughed lustily as he followed her.

…...

A week later Harry was frowning as he tried to remove his underwear. Hermione came into the bathroom, "Sorry Harry. I enchanted them so that only I, or Luna, could get them off of you."

"You do know when I have to go to the bathroom this is going to be quite the bother." He said grumpily.

"I know. But Ginny stole the formula to my repression potion. Its out all over the school and there are girls using it to see who they are the most repressed for." Hermione said, "I just wanted to protect the precious to ensure there was no unfortunate misunderstandings.

"The precious?" Harry asked.

Getting on her knees in front of Harry she kissed the bulging portion of his anatomy with a growling purr she said, "Yes the precious."

"Oh. Okay!" Harry said in a rising tone of enjoyment as she showed how precious she found it.

…...

A month later the side effects of the potion when consumed in great quantities had been revealed. It had changed the girl's anatomy to whenever they got sexually excited for anyone their bosom swelled, the more excited they were the larger they got. Expansion and levitation charms were mandatory on all forms of female garments.

Neville sighed as he said, "Well at least there's no trying to figure out if a girl is into you or not anymore."

Seamus chuckled, "Yeah all you have to worry about dating Susan is not being smothered to death."

Neville looked across at his blonde haired pneumatically enjoyable girlfriend and grinned happily, "Yeah but what a way to go!"

…...

Years later and the madness of the blissful bosom blow-up had not been passed to their prodigy Hermione and Luna Potter enjoyed a happy, unrepressed life with their husband Harry. She still showed him how precious she felt he was to her and he still enjoyed their bountiful love for him.

Shadeymankey: Post Hogwarts ones can be a bit sad sometimes I suppose. Glad you liked the other one though.

Freddie Rindklip: Yeah. It was not exactly meant to be anything more than a brief sad tale.
