Chapter 1

Because of turning the wrong page of a particularly dangerous spell book, Hermione was dying. The only way to get a cure, she found out, was to turn into a boy using the polyjuice potion. At first, she thought that that would be a simple matter. She had brewed the polyjuice potion in 2nd year, after all. She soon found out that cross-gender transfiguration was notoriously difficult. The main ingredients to the potion were the following:

1. Pubic hair from 2 different boys
2. Armpit hair from the same 2 boys
3. A semen sample from the same 2 boys
Note: Boys must not be aware samples are taken from them

Hermione swallowed hard, looking at those ingredients. Obviously, those two boys were going to be Harry and Ron. But ... armpit hair and pubic hair? And semen!? Hermione felt a small tingle down her spine, suddenly imagining seeing her best friends naked. She had never actually seen naked boys before. Maybe a cousin when she was really young. Hermione swallowed harder, suddenly thinking of how to get a semen sample from the two.

And she had to somehow obtain all of this without their awareness! Hermione shook herself, she had to plan this out right.

Deep into the night, Hermione slipped into the boy’s dormitory. She got into the room Harry and Ron shared with Dean, Seamus, and Neville. Only the small nightlights beside their beds were giving any light. Each of the boys had a four poster bed, identical to the girls’ dormitory. All their curtains were drawn, except maybe Dean’s.

Hermione stood very still at the corner, assessing if everyone indeed had gone to sleep. There was no sound except their soft breaths. She nodded to herself, and went first to Harry’s bed. Hermione’s heart was pounding hard as she got to the trunk located next to his bed.

She opened the trunk, and after rummaging around found what she was looking for: the Invisibility Cloak!

With that in hand, she slipped inside Harry’s bed, and put the Cloak next to her, ready to put it on the second Harry looked like he was stirring awake.

Finally, heart pounding, Hermione turned to look at Harry, her first choice of obtaining the ingredients. He was fast asleep, looking so peaceful without his glasses, his unruly hair askew. Hermione felt a tingle that went down to her genitals, as she wondered if the hair under his arms and on Harry’s genitals were just as unruly as on his head. She felt her vagina moisten as she looked upon Harry.

It wasn’t that cool, and Harry hadn’t put the blankets over him, which was a good thing. He was just wearing a shirt and boxers. Swallowing hard, Hermione scooted over nearer oh so slowly. She was going to go for the easiest ingredient first: his armpit hairs.

One of Harry’s arms was already up, as he cushioned his head with his right arm. As slowly as she could, Hermione grabbed at his sleeve, and slowly pulled it, to reveal a small tuft of hairs growing on his armpit. Hermione couldn’t understand why seeing this made her so aroused. Quick as she could she grabbed a tuft of Harry’s armpit hair and snipped it with a scissors she had gotten for the occasion. She exhaled a quiet relieved breath, and put the hairs in a small cup, labeled “Harry”.

Okay, now for the part she dreaded, and as her moist vagina pointed out, the part that was arousing her.

Hermione wondered how to proceed without waking Harry up. The spell book had clarified that the unaware boys couldn’t be enchanted to sleep. So she had to rely on stealth. Good thing Harry was a deep sleeper.

Hermione slowly positioned herself nearer to Harry’s boxers, which were, to her aroused surprise, showing a bump on his crotch area. She had tried to look at some pictures in the library to prepare herself, but the magical library was woefully inept in regards to photos of naked men.

Hermione bit her lip and just threw caution to the winds. She grabbed at Harry’s boxer strap, feeling the warmth of his flesh, and quickly pulled it down. As she did, she saw starting from his exposed belly button right above his boxers, then down further a smooth expanse of skin, and then finally she saw his pubic hair. Her heart gave a lurch. She kept pulling down, looking at his unruly black pubic hair as it gave way finally to his penis, which flopped out as it got exposed.

Heart beating hard, Hermione stared at her best friend’s exposed penis, the first penis she had ever truly seen, right in front of her. For a moment, she just stared at Harry’s genitals.

It looked half erect, with enough hardness to point straight up to his belly button. It might have been 3 to 4 inches. Its head was exposed, and from Hermione’s limited knowledge, this was a circumcised penis, seeing a scar around his shaft. Harry’s pubic hair was growing just at the base of his shaft, and a light dusting on his balls. Hermione felt the moistening of her vagina lead to a drop of arousal running down her leg.

Now exposed, Hermione watched in amazement as Harry’s penis seemed to react and chub up a bit more. Hermione shook herself, reminding herself of the job to be done. She reached out, towards his pubic hair, careful not to touch his penis, which was so close. Picking a strand of his black hair, she snipped it quickly and put it in her Harry cup.

Now to the most challenging part ... the semen collection. Hermione knew that she was going to masturbate Harry. She knew how masturbate herself, but was more of a loss with how to do it with guys. This was why she was here now without panties under her skirt. She had planned to learn to masturbate Harry by masturbating herself.

Hermione raised her skirt up, to expose the V between her legs, which was covered by her curly brown pubic hair. This barely hid her very erect clit, and moistened vagina. There she sat next to Harry and his exposed penis with her own exposed genitalia.

Hermione crept one finger down to her clit, something she had been itching to do the moment she had seen just Harry’s exposed hairs. She bit her lip to stop a moan from escape, and she could feel herself wetting Harry’s bed with her arousal. Okay, if a girl masturbated by touching her clit and rubbing her vagina...

Hermione slowly reached out and hovered over Harry’s half erect penis. And then slowly, she grabbed hold of it. It was like a jolt of electricity down her spine as she held onto his spongy penis. It was so warm and soft. Oh, oh, oh! At the touch of her soft feminine hands, Harry suddenly groaned.

Hermione froze, her right hand around Harry’s penis, her skirt up exposing her own genitalia, and her left finger on her clit. But Harry didn’t wake up.

Slowly, Harry’s penis started to grow to its full erection with her hand around it. Hermione watched in amazement as she felt blood pump into Harry’s appendage. The soft flesh she held became firmer, she looked at the crown of the head of Harry’s penis enlarge. She marveled at how smooth his shaft was even as it grew. Finally, she thought, it was fully erect, at maybe 5 inches or more. It seemed to strain against her hand, and for a moment, Hermione just stared at it.

Okay, now how to masturbate a guy? She, herself, had learned to masturbate after entering Hogwarts. Most people were just starting puberty as they entered the school, after all. She looked down at her left hand next to her curly brown pubic hair and her clit. Just the image of her naked self and her hand around Harry’s exposed penis made her want to cum. She need to release all this tension. Slowly, she began to rub herself.

Shivers of pleasure went through Hermione, and she bit her lip trying to stay quiet. Alright, she needed Harry to feel the same way. How to rub him the same way she rubbed herself? Holding onto his warm penis, she experimentally squeezed it. To her amazement, it was very pliant and firm against her touch. Hermione continued to rub her clit as she squeezed at Harry’s penis.
