Chapter Eight

Harper had to try her best not to squeal out loud for joy upon seeing how much the size difference between herself and John had narrowed. Only her sense of self-control (and her respect for the library space) prevented her from such an ecstatic outburst. At 5’5, 138 pounds, Harper had gained 4 inches and more than 20 pounds since John had last seen her the previous night, when she had been riding his dick into oblivion. Less than a day before, John had been an entire foot taller than her, and had outweighed her by more than 60 pounds. But now that her growing, and John’s shrinking, had commenced simultaneously, she was only 3 inches shorter than him, and only 26 pounds lighter. The difference was immediately striking as she stood there in front of him, unable to keep the gratified grin off her face. 

But the pure statistics of the narrowing size gap wasn’t the only noticeable difference. Right as she had turned around to greet him, John had been walloped upside the head by the fresh vivacity and color of Harper’s face: the plush volume of her lips, the perky fleshiness of her cheeks, and the sparkling brightness of her hazel eyes. He had already been captivated by her ever since they had met the previous week after class, but now, Harper could tell from his stunned reaction to her vigorous new appearance that his appreciation for her beauty had reached a new level. 

For her part, Harper couldn’t help but notice (again, with an exited spring in her heart) that John wasn’t just looking shorter and skinnier — he was looking, well…a little drained. There was no other way to put it. And, as Harper told herself, it was the truth. She had literally drained the life-force, and the size, straight out of him. She glanced down at John’s clothes hanging looser on his body, and on his slightly-too-big shoes, and then averted her eyes back up (and only slightly up) to his face. She could see that his cheeks looked a little thinner, a little haggard. Anyone else would have just assumed that John had pulled an all-nighter, or else just partied too hard, but Harper knew the truth. She felt a little twinge of pity tug a little at her insides, but she waved it off. She knew that he wasn’t in any real danger…everything that he thought he held dear — like his status as a man — was in danger. But Harper was about to introduce him to a world of forbidden and untold pleasures that would completely undo and upend anything he thought before. Even if he didn’t know it yet, he was one of the luckiest young men in the world. 

“Wh-what’s…what’s going on, Harper?” asked John shakily, trying to focus his mind on the task at hand. It was quite difficult, however, to ignore the erection that was already starting to tent his oversized pants. The taller, brighter, more curvaceous Harper was proving irresistible. 

“Welllll,” she said flirtatiously, taking a step up to him as she flaunted her enlarged cleavage in his face. “A couple things. It’s pretty simple, actually. I’m growing…and you’re shrinking!” 

“I’m…b-but…but how?” he sputtered, a little too loudly. 

“Shhhh,” said Harper in a gentle warning, putting a manicured finger up to her full lips. John saw that she had painted her nails the same hazel color as her eyes…and had apparently sharpened them too. They looked pointier than usual, even though they had already been sharp before. 

“Sorry,” John said in a lower voice, but his eyes were still wide with pleading desperation as she bent down towards her face. He didn’t have to bend far at all. “How is this happening!?

Harper’s mind and body were buzzing with excitement. This was the moment of truth — she didn’t know what was going to happen, but it was going to feel so good, just to speak her reality out loud to a regular person. Her eyes, which were just a touch taller than John’s mouth, sparkled mysteriously as they looked slightly up, and straight into his. 

“I’m a witch, John.”

She spoke the words barely above a whisper, but they went straight into the center of John’s body. He just stood there for a few moments, his mouth slightly open, his brain lagging behind in his skull as he tried to process what she had just said. But suddenly, everything seemed to fall into place. The hushed rumors about the Kappa Gamma Delta house…all the small guys dancing with the taller, larger girls…the mysterious sparkle in the women’s eyes when they all looked at him…and Nora! Her…her potion-making on the porch just a little while before! It all added up in his mind, fulfilling a number of cliched assumptions he had about what a “witch” really was. John knew that what he was thinking was crazy, and that what Harper had said was crazy…but he had already gone through the exhausting motions of resisting the truth all day long. The reality was prominent in his mind, and he knew that it was staring at him in the face, smiling as steadily as she was: Harper was telling the truth. He took a step back from her, and his heart rate compelled his breathing to increase in tandem. 

“No…no, John! Don’t be afraid, please!” implored Harper, still in her soft tone. She held out her hands to him beseechingly. “I’m not going to cause you any harm, John — ever.” 

“I…I d-don’t…I can’t —” John stuttered, not knowing what he was going to say, but Harper closed the gap between them and wrapped her arms lovingly around his upper torso, her hands snaking around to his back, and then to the base of his neck, where she started scratching him affectionately with her fingernails. John felt shivers spill down his spine, and emanate outward to his limbs. It felt sooooo good to be touched this way, especially from someone as gorgeous as Harper. His worried eyes looked into hers; she stared back at him, intently, but still with such a degree of adoration that he could not look away. This girl really liked him. No one had ever looked at him like that before, least of all a girl who looked like her. Even as John felt his resistance waning, he tried to hold strong. 

“I don’t want to get smaller,” he whispered, shaking his head slightly as he looked down at the floor. For some reason, he couldn’t bring himself to look into her eyes when he was talking. The mere thought made him feel…ashamed. “I don’t wanna be like those skinny…tiny guys at the party last night.”

“Awwww,” said Harper gently, moving her right hand up to the back of his head as she continued her tender scratching. “Don’t worry John — you don’t have to be like them!”

“I…I don’t?” he asked uncertainly.

“No!” she answered, smiling brightly. “It’s all up to you, where we go from here!”

“B-but…but I shrank, Harper! I shrank last night and — ”

“Shhhh!” she giggled, sticking her chin forward a little in urgency. “The library, John — remember — yes, you shrank a little last night, but the shrinking’s done! It’s all over! If you want, you never, ever have to shrink again.”

“But…we had sex…that was how….that’s how…oh god, I’m so confused right now!”

John closed his eyes and put his face in his hands, shaking it back and forth. Harper pulled him closer to her. 

“I’ll explain it all John…it’s simple,” cooed Harper in his ear. “You shrank because of two reasons: you drank our special Pink Panther last night, and then we had sex. If you have the drink without the sex, nothing happens. And…” — and here Harper’s eyebrows danced a little — "if you have the sex without the drink…nothing happens either. No shrinking, unless the two are combined.”

“I…oh,” said John, his face emerging from his hands. His eyes were screwed up in concentration, and his whole body seemed to pause as he digested what Harper had said.

“So…so after I had the drink…and we had sex last night…?” 

“I fucked the size out of you,” whispered Harper dirtily, winking at him. “I fucked it out of you and sucked it straight up…into me.”

“S-so…you…you took my size!?” stammered John.

“Mmhmm,” nodded Harper. 

John suddenly put his face back in his hands and started shaking it back and forth all over again.

“Oh god…oh god!” he moaned. 

“Shh, it’s ok, John, it’s ok!”

“No it’s not ok!” John’s voice came from behind his hands, which were still on his face. “I’m four inches shorter than I used to be!” He quickly took his hands off his face as an idea seemed to have struck him. “But I can change back, right!? Like…y-you guys…can make me grow back, can’t you??”

“Sure we can,” answered Harper genuinely. “You’ll just have to talk to Nora about that — I’m not anywhere close to that level of potion-skill yet, haha.” 

“I can switch back…” breathed John, looking past Harper, speaking almost to himself. “I can change back…I can get it all back…”

“Mmmm yes, you can get it all back…if you really want to.” Harper started lightly swinging his body back and forth in her arms, almost like they were doing a slow-dance in middle school. John was struck by how…evidently strong Harper had become. She certainly wasn’t having much trouble moving him around. He thought back to Nora…and Ariel…and Vera…and just how…solid and strong their bodies looked. But more than anything, for the first time that day, he was starting to feel something like relief — all of this could be reversed. 

“So no need to worry, ok?” reassured Harper, bringing him back and giving him a playful little shake. “I mean…you might have to make some choices…but like I said, it’s all up to you!”

“Choices? What kind of choices?”

“Take it all up with Nora, ok? She knows all the ins and outs of the potion stuff. I could try to tell you, but I don’t wanna say anything that isn’t accurate, you know?” 

“Uhh…yeah…sure, ok,” nodded John. They stood there for several moments, flanked by bookshelves, as Harper continued to look up into his face as she swayed his body back and forth, back and forth. There was no way for John to avoid the thought that the dwindled size gap between them was really…highlighting Harper’s assets. Her boobs had always been perky and spry, but now they looked…well, very big. Like, noticeably big. They stretched her t-shirt out suggestively, enough to where it was notable. And her…just her whole figure…her hips and thighs swelled alluringly in her skin-tight jeans, and from behind, John could tell that her ass was definitely bigger. She had been hot and sexy before…now…now she was even hotter. John was still trying to get everything straight in his head, but the promise of getting his size back allowed him to assume a sense of normalcy for the moment. He looked down at Harper, and she blinked and smiled back at him. He couldn’t be angry with this girl, not when she looked at him like that. And now when she was…just…everything she was. But he had to say something. 

“Harper,” he said in a business-like tone that made her giggle, and then he found himself helplessly starting to smile too. But he kept talking through the smile. “Harper, you…you guys shouldn’t be playing those…those kinds of jokes on people!” 

“Oh, but it’s not a joke John, it’s not!” she laughed, shaking her glorious, thick auburn hair back and forth. ‘It’s definitely thicker than it was before,’ thought John. 

“Well…yeah, I know, because…because it’s not very funny!” responded John, undercutting his words with the grin that was splayed across his face. “You all…you guys should…should ask permission before you pull that kind of crazy stuff on people!” 

“Oh but if we asked permission,” said Harper knowingly, “Then who would agree to it? Haha, no, no, we give guys a little taste first, and then just see if they like it. If they don’t, then of course they’re free to switch back, like I said.”

Harper let him go and took a couple steps back, doing a few 360-degree turns as she showed off her new curves. “So how about it? Do you like it, John?” 

Their voices were still spoken in whispers, but Harper’s body was speaking a lot louder. John’s eyes were helplessly drawn to every new curve and contour…and just the way she was moving…the new vivaciousness and confidence that she seemed to have. All of it was more than enough to make John’s cock fully hard, a hardness that had already been fast approaching.

“I mean…” he answered, grinning as he held his hands out to indicate the obviousness of the answer, “Yeah…duh…haha!” 

“Aww, thankssss,” purred Harper. John wanted to have sex with her…right then. But a thought suddenly interrupted his lustful drive. 

“But…you’ll…you’ll shrink, right?”

“Pardon?”

“When I get my size back…you’ll shrink, won’t you?” John was trying to be diplomatic here. “I mean…Harper…I always thought that you were hot, so it’s not like I’m saying that you’ll — ”

“I know,” she interrupted as she sauntered up to him and shushed him with her finger, “What you’re saying…and it’s ok! Don’t worry! That size I took from you…I’ll have it with me…always.”

She breathed the word “always” sensuously into his face. 

“So…you’ll stay like this…even when I grow back?”

“No matter what you do, John…I’ll never be 5’1 again.” 

“Wow…” 

This all seemed to be working out ideally as far as John was concerned. He could get his size back…and his girlfriend…or, well, soon-to-be girlfriend, at least (when he asked her out), had somehow become even hotter. He had been struggling with so much anxiety so far that day, and now it all seemed to be just fruitless worry. He wasn’t able to help laughing quietly again.

“Haha, gosh, Harper, you guys…all you Kappa Gamma Delta girls…how do people not know about all this stuff?! I mean, like…how are you not…like, on the news all the time or something!? Haha, like scientists studying the potions and stuff?”

“Oh, lots of people know about us,” said Harper. “But the ones who do…they’re usually not eager to talk about it.”

“Why not?” asked John blankly. “This is incredible! You guys can actually shrink people, and…and grow people…and transfer size!?! It’s some kind of crazy science discovery that — ”

“Shhhh, library!” laughed Harper a third time, quieting him down. “We’ve known about this stuff for a long, long time. Since ancient times, actually. It’s just been covered up in the annals of history.” 

“Uhhh…” said John. His head was spinning with all this new information, but he was becoming increasingly distracted by Harper’s knee in his groin. 

“We can talk about that stuff…later,” whispered Harper in his ear. 

“So…you said that we can have sex…like, just sex…and I won’t shrink anymore, right?” breathed John. 

“Riigghht." 

John glanced around. There were a fair amount of people in the library, and it was just then that he noticed that the crazy idea to have sex on an abandoned book aisle had popped into his head. He would’ve never thought of such a thing before…but then again, he had never met someone like Harper before. 

“Handicapped bathroom?” purred Harper in his ear. 

“Or…wherever!” laughed John. 

A minute later they were stripped down naked in the handicapped bathroom, which was a single-use room that had the benefit of enabling them to lock the door. Harper had John sit on the toilet seat, with his cock pointing straight up, and she had slid down onto it, reverse-cowgirl, taking care to rivet and rile him with sways and bounces and heavy fluctuations of her big ass. John put his hands on her cheeks as she rode him, and her bouncing cheeks made his hands go up and down, left-right-left-right left-right. Her butt had been big before, but now it was just…extremely large. 

‘Nothing like Nora’s though,’ said a little voice in his head. ‘Or those other girls’…’ 

But John was easily able to shake away this distraction. The girl of his dreams was riding him like there was no tomorrow. They both knew to hold in their moans and cries, and the effect of their short panting breaths echoing off the bathroom tile was somehow more erotic than moaning. Within a minute or so, Harper was leaking little streams of ejaculate down into John’s lap, where it pooled and started running down his legs. 

“Oh godddd,” whispered Harper. “I’m cumming…I’m cumming, John…holy shit I’m cumming!”

Her passionate whisper, her delicious sandalwood scent, the feeling of her cum dripping down his legs, and her strong, curvy, supple body continuing to ride him without slowing…and the inherent “dirtiness” of what they were doing…it all added up to a seizure at the base of John’s dick. 

“Me…too,” he breathed, and just like that, Harper leapt off his cock, got on her hands and knees in front of the toilet, pushed his legs apart, and shoved his exploding length into her mouth. Down, down, down she took him, until her full lips were smooching over and over around the base of his cock. She had just deepthroated the whole thing…her throat swallowed once, and that signaled the moment of lift-off. John rocketed shot after shot of cum down her eager throat, which she instantly and eagerly gulped down. When she finally came off him, they both just stared at each other, breathing hard, in disbelief at the unprecedented sexual intensity of the encounter. Then they both just smiled and started laughing. 

“Holy…fuck!!” exclaimed Harper. 

“Y-yeah…shittt!” agreed John.

“I’ve never done that before,” she said.

“What, deepthroated someone?”

“Yeah!”

“Well…haha, I guess I’m your first!”

“Yes…you are.

The sound of someone trying the door handle snapped them back to reality, and they quickly threw their clothes on and shuffled gigglingly out past the person who was waiting outside. A minute later they were standing outside the library. 

“So…so I go talk to Nora about this whole…size thing?” 

“Yep…she’s the one to see about all that.”

“You wanna come with?” asked John. “You know…for moral support, haha?” 

Harper blinked and for a second her brow creased just a bit. “No, I can’t, sorry! I told some of my other sisters that I’d be going to a movie with them.”

“You mean some of the other witches, huh?” chuckled John. 

“Haha, yes,” laughed Harper. There was something that had fallen over her, though…almost a kind of sadness. 

“Well…ok, then, that’s all cool,” said John. It suddenly occurred to him that maybe Harper was waiting for him to ask her out, and that’s why she was acting a little off. It seemed almost perfunctory at this point, but if he was going to do it, now was definitely the time. 

“So…I wanna see you again,” was how the words came out. He realized his mouth was dry. “Do you…do you wanna keep doing this?”

“Oh John!” said Harper, throwing her arms around him and hugging him tightly to her. “Yes of course I do! I like you very, very much.”

There was still something like sadness…like wistfulness…in her voice, and in her face when she released him from the hug. 

“So…you wanna be my girlfriend?” ventured John, feeling the moment stand still in time. 

Harper’s eyes started shining with tears.

“Just…go talk to Nora…and then get back to me, ok?” she asked thickly through her tears. Before John could say anything more, Harper had turned and gone, walking quickly away down the sidewalk, her oversized bookbag bouncing underneath her big ass.
