Chapter 14 - Test Subjects
The bargain with Ginny had turned out to be more sexually rewarding than Harry had first thought. There was a plethora of potions and spells he and Hermione wished to test out, and Ginny was more than willing. The other unforeseen benefit was that Hermione agreed to use the control spell on any other girl Harry wished to use as a test subject.
The trio woke up to a beautiful Saturday morning and went over their prospective list of spells and potions that required testing. It looked like they'd have the whole day to themselves, with no homework or Quidditch practice to distract them. As Hermione ran off to ensnare a second test subject, Harry and Ginny made their way out into the grounds. The two potions he would be trying were nicknamed for simplicity; Maturity and Dopey.
Maturity read:
A simple but effective potion, which is able to temporarily age a female drinker to perfect sexual maturity. The spell only lasts a single hour.
Whilst Dopey read:
A powerfully effective sleeping potion which will cause the drinker to fall into a deep and relaxing sleep. They'll remain unconscious for an entire hour!
Like the vials of Hot Sauce, the labels on every single one of his handy little sex potions were enchanted to appear only when a secret phrase was uttered and the label tapped. He'd only reveal the secret password to identify which was which.
Because it was going to be such a beautiful Saturday; that they decided that the best place to try out the potions would be outside in the gorgeous sunlight. It was under this idea, that they agreed to meet near the Whomping Willow, a secluded and safe location. Harry and Ginny sat on the hill nearby, basking in the sun, with Harry's hand immediately moving to caress Ginny's perfectly shaped breasts.
"Oh Harry!' Ginny breathed, as she felt her nipples harden to his soft touch. The pair closed their eyes and enjoyed the sunshine, Harry's left hand continuing to caress Ginny's breasts
"Hey guys!" a voice said cheerfully, Harry opened his eyes to see Romilda Vane walking toward them, beaming.
"Mione?" Ginny asked, she understood the spell, but she was cautious in case it was really Romilda being friendly.
"Yep, managed to get her when she left her dorm room, I'm safely protected on my bed, wihtt he curtains drawn so only I can open them." Romilda said sitting down on Harry's right hand side.
"Why Romilda?" Harry asked, his eyes examining Romilda's fairly beautiful face, left hand not leaving Ginny's chest.
"Because it's no secret that she has the hots for you" Romilda said quickly, in Hermione's impatient tone. "So this'll be a nice, realistic dream for her." Ginny got up and cast several privacy wards, along with 'Muffliato' as an added precaution. Harry reached into his pocket and handed Romilda the bottle he identified as Dopey. Deciding to test Maturity on Ginny.
"Drink these and the reactions should be immediate" smiled Harry. "They're perfectly safe... I wouldn't test them if they weren't!" he added with a smile. Ginny took it as the truth before removing the potion stopper and consuming the contents in seconds. "mione, you could join us, I'll use Dopey on Romilda, but you will need to hurry." Romilda nodded before consuming the contents.
Harry saw a flicker in her eyes as Hermione abandoned her control, before she passed out
"I feel weir..." started Romilda, before she fell unconscious onto the ground.
"This potion feels really good!" replied Ginny, as her body began to change. Romilda remained unconscious while Ginny's entire body shifted, becoming taller, and her body became curvier, making her an unbelievably gorgeous eighteen year old girl. What made the situation even better was the fact that all of Ginny's clothes were now far too small for her and accentuated her perfect body. Harry immediately got hard at the sight, as Hermione walked calmly from the hidden passage under the Willow.
"Time turner" Hermione smiled as Harry gave her an odd look. Harry then pointed at Ginny as he looked down at his unconscious test subject and decided that it could have been worse, before pulling off his clothes and getting onto his knees in front of Romilda.
"I'm so horny!" moaned the adult sized Ginny, as she stroked her pussy through her skirt and panties.
Hermione basically tackled her to the ground after saying she was horny, pinning her to the ground and helping her to remove her tight clothing. Hermione tore off her own clothing as she lay on top of her prize, who was still in the process of rubbing her pussy. Hermione proceeded by unclasping Ginny's tiny skirt and tearing off her dress shirt and tie. Hermione was pleasantly surprised to find out that Ginny's bust size had increased substantially. She hadn't worn any bra before because she had nothing to support, so when he removed her shirt, her perfectly large breasts were completely visible.
Ginny gave her a quick wink before Hermione straddled her chest, summoned her cock and guided it toward her beautiful mounds. She gave each one a playful squeeze before forcing them together and rutting her hard cock between them. It felt so good to both Hermione and Ginny, who by this point loved the attention she was getting. Ginny may have looked like a hot and slutty eighteen year old, but in reality; she was the same girl as before. Hermione spat down onto her cock, helping it slide faster and smoother in between Ginny's gorgeous globes.
While Hermione titty fucked the horny Ginny, Harry was occupied in removing Romilda's school uniform. Romilda was a fairly attractive girl that Harry had never noticed. Now that she was completely defenceless to his advances, Harry was more than ready to take advantage of her situation. After getting her completely naked, Harry took a good long look at her attractive figures; her perfectly sized breasts, her tiny pink nipples and little fuzzy strip of black pubic hair located just above her tight pink pussy were very attractive. Harry couldn't be sure yet, but he had a nagging suspicion that Romilda was more of a virgin than Ginny.
"Let's see that ass!" Harry said to the unconscious Romilda, flipping her over in the process and getting a great view of her big juicy ass. Harry was surprise by how much junk Romilda had in her trunk and couldn't help but lie on top of her and begin to move his eight inch shaft in between her ass cheeks like Hermione was doing with Ginny's breasts.
"Ohhh Goddddd! It feels so good!" groaned Ginny, enjoying the sensation of Hermione's cock as it moved like a piston between her sizeable breasts. Hermione couldn't take it any longer and needed a taste of the beautiful Ginny again. She got between her legs and watched as Ginny continued to move her fingers in and out of her panties. Hermione bent her head down and got a great whiff of Ginny's pussy before using her teeth to grab hold of the thin material and tear off her panties. He threw them aside and moved his mouth in closer, sticking the tip of her tongue as deep into Ginny's pussy as possible.
"Ahhhhhh!" screamed Ginny, the sensation of the long tongue penetrating her caused her to scream out in ecstasy. Hermione continued to eat Ginny out for the next five minutes, only breaking away when she went through her two orgasms. The urge to fuck her overpowered Hermione, and she made to truly enjoy Ginny's mature form. Before she did however, she looked over at the scene developing only feet away and was surprised to see that Harry had already beaten her to the punch.
"Fuck this pussy is tight!" moaned Harry, humping into the unconscious Romilda while she remained on her stomach. Harry had spread her legs and was slowly working more and more of his shaft into her tight teen pussy. After a few inches, he quickly realized that Romilda was in fact a virgin. He continued to thrust into her flexible hymen for another three minutes before he tore through it, causing her to bleed from her pussy and coat his cock. "That's better!" he sighed, as he started to pump his cock into her with a little more freedom. "How's it going over there Mione?" Harry said as he propped himself up with his hands on the ground.
"She's so wet!" laughed Hermione, as she slid her cock into and screaming Ginny. Ginny's eyes were wide open in pleasure as Hermione's cock filled her tight pussy. She shut her eyes and rode another climax. Hermione grabbed hold of her jiggling breasts and pushed her shaft as deep into her as possible.
"FUCK ME HARDER mistress!" moaned Ginny, as her orgasm subsided and the pleasure from Hermione's thrusting began to increase. She wondered why she hadn't asked for this before as she felt Hermione twist her nipples and begin to kiss her neck.
Harry gave Romilda's juicy ass a few sharp slaps to watch it jiggle even more as his cock continued to move in and out of her pussy. Harry could swear he could here Romilda moaning under her breath every time he thrust his cock into her and he was sure she was having one hell of a dream.
Hermione in the meantime had Ginny's legs up over her shoulders and was pumping her cock into her as hard and as fast as she could. She knew it wouldn't take her very long to reach her end and she wanted to make sure she would be able to get Ginny to reach hers at least one more time before she did.
She was in luck too; just as she began to pant and near her end, she heard Ginny begin to squeal in pleasure before her juices enveloped her cock that continued sliding in and out of her. The added sensation of her pussy clutching and her juices coating her cock was more than enough to push Hermione over the edge in the process. She had no intention to pull out of the young teenage slut, deciding that because she would transform back into her younger self in only a few minutes, a healthy dose of potent seed into her womb would probably not impregnate her. Either way, she knew Ginny was willing to take the chance.
"UNGHHHHH!" grunted Hermione, jetting several wads of hot sticky cum directly into Ginny's fuzzy eighteen year old pussy. Ginny closed her eyes in pleasure as she felt Hermione fire several long thick strings of her warm semen directly into her for several seconds.
"GOD! I can feel you shooting inside me mistress!" moaned Ginny, not realizing that if she had actually been eighteen, she would in fact have been impregnated by Hermione's large load of cum. Hermione finally stopped cumming after several seconds of grunting and instead of pulling out of Ginny, she just remained inside of her and rested her head between Ginny's large breasts, as Ginny held wrapped her legs around Hermione's waist, keeping her inside.
As Hermione finished going through her orgasm, Harry began to go through his own massive orgasm. Unlike Ginny however, Romilda was definitely impregnable, but Harry cared little for that as he began to pant. He and his clone had already impregnated Katie Bell and Alicia Spinnet, so getting Romilda pregnant mattered little, especially when nobody would be able to prove his little act with Romilda after she awoke from her deep sleep.
"FUCK! I'M CUMMING!" screamed Harry, as he slapped Romilda's now red ass one more time and began cumming inside of her tight cunt. He painted Romilda's womb with four thick strands of hot seed deep inside of her before collapsing on top of her in ecstasy and relief.
"Mistress?" Hermione asked as she pulled out of Ginny and vanished her cock, Ginny blushed as her body began to return to normal.
"You sort of are Mione" Ginny said defensively, as the two women began to redress, Hermione's cum trickling down Ginny's leg. "I'm a subject for your lustful spells, and I love it!" She flung herself at the couple and hugged them tightly.
"I'm fine with that" Harry said carefully redressing Romilda, and then himself. Hermione nodded her agreement and kissed Ginny on the lips, which made Harry's cock strain against his boxers.
"Welcome to our strange little relationship" Hermione said when she finally stopped kissing Ginny.
"Mione, would you kindly return Romilda to where you found her, we'll guard your body." Harry said, pocketing Romilda's underwear. Hermione nodded and sat down as she cast the spell on Romilda.
"Good idea master! said Ginny, as she and Harry sat down on the hill again, Harry remembering what her breasts were like moments ago, went back to caressing her chest.
Ten minutes later Hermione passed out and Romilda awoke, without saying a word, she hurried back toward the castle. Another ten minutes passed befoere Hermione awoke.
"Left her in a chair in the common room, she'll think she fell asleep there" Hermione reported, before she sat on Harry's other side.
"I think we can say those products work just fine ladies!" Harry said to his women, as slid his hands under their tops and gently squeezed their breasts playfully.
"I love that book" replied Hermione and Ginny in unison, as they enjoyed Harry's expert fondling.
"Who or what is next?" asked Ginny, leaning in closer as Harry wrapped his arms around them, and felt the breast furthest from him.
"Let's see how everything unfolds" groaned Hermione as Harry's fingers twiddled her erect nipple.
"Well, I'd like a threesome eventually with you two" Harry suggested, they responded by kissing him on the cheeks. "And maybe fuck your asses?" he added. The two froze before shrugging. All three lay in the grass for the rest of the day, enjoying the weather and Harry's playful hands, until the sun began to set. That night, both girls snuck into bed with Harry, using the cloak to enter his dorm, for Harry, he was having the best year ever, nothing could dampen his spirits.
