Go back for seconds (and more)

The next day at Hogwarts was a normal day in every way except for two. 1. Hermione found it difficult to sit anywhere and spent the day shifting around in her seat, muttering to herself. 2. Harry's mind was completely occupied. Never the most attentive student, today Harry wasn't even putting in any effort to paying attention to his classes. How could he when his mind swirled with thoughts of his newfound powers? Thoughts of his friend, Hermione's tight ass wrapped around his cock? Thoughts about whose ass he was going to take next? Of those thoughts, he was able to find an answer to one. The last one. Though he had greatly enjoyed taking her anal virginity, Harry was far from finished with Hermione's rear end.

From looking at her and listening to what she was saying during their conversations, it quickly became clear to Harry that the idea that she would be fucked in the ass again had not crossed her mind. Poor girl. She may have thought it was a one time thing, but Harry needed to gather more power. Even if he didn't, he wanted her ass again desperately. Just the one time fucking her woke something up in him, only making him desire her even more than he did before. However if there is one thing Harry was learning, it was patience. All day, he played it cool, not saying anything to tip her off, or tip off their friend Ron that anything had happened between the two of them. So, Harry bided his time, waiting all day for just the right opportunity, and late at night, one landed right in his lap.

As they were discussing classes (mostly all the material that Harry had missed) Ron yawned loudly. "Well, I'm tired, and for once, I actually understood what was going on in class, so as fun as this is, I'm going to bed."

Harry's heart raced with anticipation as he said, "Night Ron. See you tomorrow morning." With a wave to his two friends, Ron was gone, leaving Harry alone with Hermione once again.

"Now, where were we..." Hermione said, picking up a scroll.

"Actually, I think it would be better if we studied somewhere else. Somewhere more private," Harry said. Given the perplexed look on her face, clearly Hermione did not get the message. "Perhaps the same place we used yesterday," he added.

Given how her face immediately turned pale, Harry figured she understood this time. "What?!" She hissed at him, trying to stay quiet to avoid attention. "That was a one time thing just to see if it the book was real or not! It's real. Mystery solved." Hermione quickly looked around, making sure that her little outburst didn't attract any attention, and when she was assured that nobody else was looking, her gaze snapped back to Harry, her big, brown eyes wide as her chest heaved with her heavy breathing.

"That's true," Harry said, speaking slowly in order to let his words truly sink in. "However, now that we know that this book is the real deal, remember the whole point of Dumbledore giving it to me in the first place. He gave it to me so that I could gather the power needed to fight Voldemort. Don't forget how that power is created," Harry said. He had to fight to keep a smile from appearing on his face so that the excitement at the idea of fucking his friend in the ass again wouldn't influence her thinking. Under his robes, his manhood reacted, hardening as he thought about how tight her butt felt, and he was thankful for the flowing fabric concealing his arousal from view.

"Well, yes but..." Hermione stuttered. "There are other girls," she said, trying, in vain, to deflect his attention.

"What other girls?" He countered. "Right now the only girl who can help me is you."

"But I'm still sore from last night!" she whined.

Sensing her resistance, Harry decided to go in for the kill. "Is it really that bad compared to what other people have sacrificed fighting Voldemort? People have given their lives. I think you can do this to help, at least," Harry said, feeling a tinge of guilt for pressuring her so hard and using such underhanded tactics.

Hermione's shoulders drooped, along with her head as she accepted his argument. Harry felt even more guilty. "Okay... you're right," she said, slowly standing up. His guilt dissapated as a wave of lust poured over him. They exited the common room, with Hermione dragging her feet as Harry kept trying to nudge her to walk faster from behind. He did wish she had a bit more to her backside as he trailed her. In her heavy robes, she could have passed for a petite boy from behind. Still, her ass was a nice shape underneath her robes, and either way he was going to enjoy fucking the hell out of it.

In a walk that felt like an eternity to Harry and all too short for Hermione, the pair soon found themselves once more in the bathroom in which Hermione had her anal virginity taken. Both of them stood around awkwardly, neither of them wanting to make the first move. Finally, Harry spoke. "Well... I guess let's get to it then." He began to undress, taking off his robe, which allowed Hermione to see that he was already erect. She blushed, though couldn't seem to look away, as this time, Harry fully undressed, throwing his clothes into a pile on the floor of the bathroom. Hermione watched the entire process intently without undressing herself, which, for the first time, made him nervous. "Like what you see?" he said, cracking a joke as he stood in front of the fully clothed girl, naked as the day he was born, with his cock standing at attention.

She blushed and didn't answer, instead going into action herself. This time, she fully undressed as well, neatly folding her clothes into a pile next to Harry's jumble of clothes. Hermione's ass was everything he had been thinking about all day, and perhaps even a little more? He could have sworn it was just a tad bigger than it was yesterday, though maybe his eyes were deceiving him. It still had that nice shape, the curve of her bubble butt nicely accented by her shapely thighs. Her chest was similar, not large by any means, but perky and well shaped, with her nipples pointed in the rather cool air of the bathroom.

"Okay, let's get this over with," Hermione said, not giving Harry much more of a chance to ogle her body. Climbing onto the same bench as last night, she laid face down and tried her best to settle herself in a comfortable position. Her tight ass was still slighty pink, and Harry could tell that she wasn't fully recovered from last night's ordeal. That didn't stop him, though, as he slathered the pale blue lube on his hard cock. "Can you be a little more gentle this time?" Hermione asked.

"I can try," Harry replied, fully intending to do just the opposite as he grabbed a handful of her bubble butt, making her squeak as he finished preparing his cock for entry. Pressing the tip of his cock against her tight asshole, Harry pushed forward, finding it to be much easier than it was the first time. He gasped as the sensation of her ass around his cock, the sensation he had been thinking about non stop, finally returned. Just being inside her wasn't enough anymore, though, and this time there was no pause to savor the moment. As soon as he pushed all the way in, Harry pulled out. Then again. And again, stretching the girl's tight asshole out. For her part, Hermione remained mostly quiet, her knuckles turning white as she gripped the bench, only letting out the ocassional whimper as Harry pushed in and out of her ass.

Knowing what to do this time, Harry grabbed ahold of her hips in order to give himself something to pull against as he fucked her from behind. He was able to savor it much more this time, watching her tight ass as he pounded into it over and over, watching the small ripples as she absorbed the impact of his body. He was able to really watch as her tight asshole gripped his cock, even as he was able to fit more into her now, and easier than last night.

"How does it feel this time?" Harry asks Hermione as he continued fucking her.

"Still hurts a lot..." she groans. "But not as bad as last time," she says.

"Okay, I'm going to pick up the pace then," Harry says.

"Wait!" she replies, but is cut off when Harry grabs her hips tightly and rams forward quickly, her sentence turning into a loud groan. Working her faster now, the room filled with the sounds of slapping flesh and whimpers of pain as the teen witch had her butt used like a toy. Her whimpering increased in sound and frequency, but besides her earlier outburst, she doesn't complain about her ass being fucked hard. Either way, Harry doesn't care. He barely notices as he fucks her ass with vigor for much longer than their first tryst. Her tight, young body clenches and her butt reverberates with each deep thrust as he forces his cock deeper and deeper into her rear end.

However, all good things must come to an end, and before too long, Harry is groaning as his cock pulsates, dumping cum into her tight little ass for the second time. Hermiome recognizes the feeling, and Harry sees her body begin to relax, seeing that she is finally done with the ordeal. He pants, coming down as he pushes the last of his seed into her asshole.

"Fuck, that was amazing," Harry said.

"Uh huh," Hermione says dismissively. "Did it work?" She said as Harry extracted himself from her rear end, remembering the book this time.

"Let me check," he said, grabbing it. The glowing number did go up, but to his surprise, it went up far less than it did the first time. I guess those bonuses the book talked about from taking a girl's anal virginity and fucking her for the first time were a lot more substantial than he thought. Of course, Hermione didn't need to kmow that. "Errr, yeah it did. More power to fight Voldemort," he declared.

She nods. "I'm glad to know all this is worth it." She looks around the bathroom and spots a shower. "I'm going to get cleaned up before going to bed this time," she said. Although the act still seemed painful, difficult, and repulsize to her, this time, it seems, she was able to keep her wits about her a lot better afterwards.

"That's a good idea," Harry remarks as he follows her. She opens her mouth to object before wordlessly shaking her head. What point is there in trying to protect her modesty when Harry has not only seen her naked now, but has fucked her twice.

With the bathroom being long abandonded, the open bay type showers have no curtains, so if you were to take a shower, you would be in full view of anyone else. Harry picks the first one he sees, turning on the water, which quickly gets hot enough for him to stand underneath. Still trying to protect some shred of dignity, Hermione tries to find a shower heard as far away from Harry as possibly, only to find each one in a non-working condition.

Seeing her try, and fail, to get any of the other showerheads going, Harry says,"Why not join me over here? I don't mind sharing." Hermione still seems apprehensive, but she knows that every minute longer they are gone together is another opportunity for someone to figure out that the two of them are gone together without Ron. With an audible sigh, she comes over to join Harry. He can't help but ogle her body, her thin body accentuated by her small but perky tits as well as her bubble butt. Hermione blushed at the stare, but she couldn't keep her eyes off of Harry's cock either. It was semi soft, though the longer he looked, the harder he got.

The two friends showered wordlessly together, with Hermione trying to avoid too much contact while Harry tried to do the opposite. It was not a long shower. Not long enough to make Harry bring up a second round of anal fun for the night, but it was pleasant to bump up against the soft body of his teenage friend. After finishing, Hermione summons up two towels, handing one to Harry, and the two of them dry their bodies off. Harry finds it difficult not to stare at the nubile body that his friend has, and he can tell that she sees him looking, though she doesn't make a comment. He does wish, deep down, that she was curvier. Her ass and breasts may be shapely, but Harry craves those women who are shapely and curvy far over those girls who are all skin and bones. Still, it's far from him to complain about a willing partner who is willing to let him violate her ass over and over.

"Okay, I have to go to the toilet to- well, I have to go. I'll meet you in the hallway!" She says, rushing off to the stall before getting dressed. This time, Harry gets dressed first, and sits listening at the door while he reads the book. The portion about changing his partner is now able to be read, and Harry eagerly reads it. Sure enough, his earlier guess is true. Hermione's ass is a bit bigger. The book says that those who are regulars of the user will change their bodies. Their rear ends and chests will grow bigger, if they are too heavy, they will lose weight. If they are not the best looking, their faces will become more shapely. And the best thing was, since beauty is so subjective, it would all depend on the preferences of the user!

As Harry read, he was serenaded by the sound of Hermione pushing his seed out of her rectum. Although not as painful as the first time, she still groans a lot as she forces the semen so recently injected into her into thr toilet bowl. Harry can't help but listen closely as the poor girl strains with the effort of expelling his cum. Harry wonders about asking her to leave it in, but he dismisses the idea as being a bit much at the moment. It takes a while for her to push out the frankly absurd amout of semen she had taken up the butt before finally emerging from the toilet, getting dressed, and heading back to their rooms.

In the next few weeks, they form a sort of routine, waiting for Ron to go to bed, and under the guise of extra studying, they dissapear up to the bathroom in order to have anal sex. After a week of daily butt fucking, Hermione finally can take it up the ass without limping the next day, and can take his cock up to the hilt without pain, though it is far from pleasurable. At least, for her. For Harry, the experiences are immensely enjoyable. The effect on her body after a few weeks is much more noticeable. Her ass and breasts have grown substantially from their previously small size, and now she struggles to hide her new assests even when fully clothed. Ron has taken notice, and both of you catch him staring quite a bit, though he always turns red and starts stuttering, not even having the courage to ask what is going on with her. Harry's power grows, slowly, but steadily, and he decides that it's time to add another girl to his rotation.
