Behind his back

Ron told her, that Harry was already sitting there and waving at them. Ron and Hermione had discussed it on the way over here: There was no reason not to tell Harry about this. He would find out anyway, right? In retrospect, Hermione wished she could have seen Harrys face as they told him about it.

"So... let me get this straight" Harry said, after Ron and her had finished. "You two are together now, so far so good. Congratulations on that by the way. But What I am not sure about is... I mean..." Hermione sighed and rolled her eyes. "Yes Harry, of course, I will still be fucked by other guys, I mean that is completely inevitable, right?"

Hermione did not want to say it out loud, but she even silently mouthed 'even you' in the direction where Harrys voice had come from. After all, being with Harry had so far always been a very different kind of fun than her times with Ron. Purely physical, but fun. "Good to know" Harry replied. She was not quite sure if he had seen her silent remark, but she did not want to repeat it.

"And what about Ron?" Harry asked "Do you want me to whack him if he goes after someone else now?" Harry joked. "Hey, mate!" Ron complained, but Hermione just giggled and said "He is still allowed to do that. But if he starts overdoing it, go ahead." Hermione and Harry laughed, and after a moment, even Ron reluctantly joined in.

While they ate, Harry told Ron a bit about how his day was going. Hearing about what he did with Cho, Hermione was scandalized at first. On the other hand though, she could not deny that hearing about the way Harry had been dominating her did trigger something inside her. Not that she was planning on calling Harry, or anyone else, Master from now on, but being taken in this way, even though just sometimes, sounded very tempting. After what Ron and she had shared now, Hermione somehow did not think he was still capable of treating her that way.

On their way up to Gryffindor Tower, Hermione listened silently while Ron and Harry were exchanging even more stories about this day. Hermione found, that she did not particularly care for Rons excited telling of how he had, as he called it, Lavenders ass jiggle like crazy.

In front of the portrait of the Fat Lady, Ron exchanged a few words with Neville, as Hermione suppressed a gasp. Someone, and since only Harry was with them, who else could it be, seized that chance to sink his fingers deep into her magically enlarged tits. As if to confirm her suspicion, she heard Harry whisper in her ear "Sorry, but there is just NO chance I am not grabbing those at least once you know?"

When Ron had turned back to them, Harrys hands had left again. This was silly, right? There was no reason to hide any of this. Although, Hermione had to admit she would not put it past Ron to get jealous, no matter what their agreement had been. But after hearing him talk about Lavenders oh so great ass like that, Hermione felt a lot of excitement at the prospect of getting groped behind his back, quite literally.

Inside the common room, things were a lot less quiet than usual. it seemed that with the lack of accountability coming with being invisible, the boys saw not much reason to honor their agreement today. Ginny seemed to be floating in mid-air, her arms flung around, well nothing, as she was happily moaning. Her ass showed visible indentations in the form of two strong hands holding her up and bouncing her up and down an invisible but from the looks on her face rather enjoyable cock.

"Ron, Harry, are you still here?" Hermione asked nervously. "Yes, I am here" they both said. To reassure her, Ron gave her hand a short squeeze. Hermione smiled warmly at this. Harry had chosen to do something similar. Hidden from Ron, he gave her ass cheeks a good squeeze instead. Hermione did not know what it was. The excitement of the day overall, the moaning around them, or just the fact that she wanted to get **** for what she heard about Lavender, but Hermione needed to act now!

"Ron? I.. well I mean this is a special night here I guess, you know with the opportunity to go for all the other Gryffindors you would not normally... well all I am trying to say is I DO mean it, you can go ahead and have fun." Some stammering later, Ron brought out the words "I.. wow! I LOVE you Hemrione!" When a second later, Parvati, who stood a few steps to Hemriones left got suddenly pushed down to her knees, Hermione was sure Ron had taken the bait.

"Wow, I would not have expected you to actually encourage him to..." Harry began, but Hermione cut him off. "Well I wouldn't, normally, but right now" she realized, that she sounded rather snappy. She calmed herself down a bit and added "Harry.. would you mind demonstrating to me once again that you are still here?" Of course, she did not see him, Not only was he invisible, but also standing behind her. But she just knew he was grinning now.

"Don't worry, I am still just behind you" Harry whispered as she felt his hands grab her ass and her boobs at the same time. Excitement shot through her body like a wildfire. When she saw Parvati falling over on all fours, she was absolutely certain. "Harry?" she whispered with a tense voice "I do not care where or how, but..." And at this moment she felt something thick and meaty glide between her thighs. "One step ahead of you" Harry breathed. The only reason Ron was unable to hear her excited gasp was because he himself had made Parvati moan rather more loudly at the same time.

Yeah, this felt right! So wrong, and so right!
