AN: I bring you my first ever Lewd. Do with it as you will you filthy degenerates.
May be short but hey, what can you expect from my first time. These types of things take time to get skilled in.
Also, sorry for the delay. Was experiencing some minor computer problems that have been quickly fixed.

POV: Casual Twincest Enjoyer

She loved her brother. That was something that she knew with absolute certainty. And she knew that he loved her too, with how he was willing to claim her as his, stay by her side, keep her sane when all she wanted to do was go mad. When he saved her from that which lurked within her.

These were things nobody else could do, neither before when she was alone, or now, due to the choker on her neck proclaiming his ownership of her for the world to see. And she loved that, the feeling of belonging that he gave her, the way his voice calmed her, the way his touch sent shivers down her spine. The looks he gave her whenever they were alone.

Before he bound her, she was unsure of such attention, unused to being desired by others and hesitant by the fact it was her other half. But that, along with any doubt and fear she had, was undone by him. Now, she would bask in the looks he gave, the feel of his touch, the pleasure of hearing his voice. Was it any wonder then that she gave herself to him, allowing her to serve her other half in all ways?

He was her everything, the Light that saved her, the Peace that ground her, The Ecstasy that kept her awake all last night, thinking only of him as she had the past three nights. A part of her was tempted to ask him to do it once again, to numb her to all feelings but him, to drown herself in his presence. But she held back, as then they had no time.

When her master decided to leave her parents and the headmaster behind, he told her that he was taking her somewhere 'special'. She admits, hearing him say that as he led her by hand caused her heart to flutter and her mind to race. Would this be it, would he take her completely, solidify his claim over her body? She couldn't wait to find out.

While it did take them a while to arrive at their destination (it would have been longer had she not dragged him away from those two statues, she saw the look he was giving them) she was momentarily disappointed that he led her to some painting showcasing that wizards had no common sense, she decided to hold back a question when she saw him pace back and forth in front of a blank wall.

Her immediate thought was that it was likely just another hidden room like the dozens they saw last week, but for some reason this one he was particularly excited about. After he performed the required steps, a door appeared, and she was pulled inside without a word.

Inside was something she never could have expected. She couldn't contain her gasp of awe as all around her was an endless sea of black, with an innumerable number of stars blinking all around her. A quick look around showed that in the distance she could make out planets she had seen only through her mother's old telescope. Behind her, above the still present door, she saw it. Earth, from a distance, took her breath away. Beside her, Harry finally spoke up.

"I found this room earlier by accident, it takes the shape of whatever the user desires, showing any view and capable of summoning any object, or at least a copy of it, from within the castle. I remember that you mentioned that you enjoyed Astronomy when we explored and were excited for the class, and seeing as we missed the first class, I decided to do something special. Uh, I'm not really sure if it's possible but let me try something really quick."

He remembered that? It was just a passing comment she made when they were discussing classes. Taking another moment to gaze upon the vastness all around her, she was suddenly aware of another sensation in her mind. Not invasive, but more questioning, seeking any desire she had.

"There, I transferred control of the room over to you, so you should be able to make any adjustments that you want."

A simple smile adorned his face, seeming to be pleased that she was enjoying the room. Idiot. Did he not realize that it wasn't the room (however nice) that made her so happy, but rather the trust he placed in her, that merely being with him was enough? Well, she would have to show him, she supposed. After all, a good servant should take care of her master's needs, and she saw how he was looking at the two mother-daughter pairs from earlier, no doubt wishing to claim them as he did her. That was fine, he deserved all the best after all, and besides, she had him all to herself at the moment.

With but a thought the room changed just slightly, fulfilling her wish and causing a smirk to grace her lips. Lips that she immediately used to meet her twins own, pushing him back and onto the bed she summoned just for this.

POV: Confused Horny Boi

What?

No seriously what?

I mean the plan was always to sleep with her, that was never in doubt, but I had thought that it would take longer than this.

As my back hit the comfortable bed, lips locked with the one's above me, I could only rely on the instincts given to me by [Sticky Fingers] and kiss back, slowly coming out of my shock. My hands were moving without my say so and I was suddenly left without my robes and was furiously attempting to do the same to my sister. Feeling what I was doing, her hands joined mine and soon the robes were off, followed by our shirts and my pants.

When we finally separated to breathe, I was left only on my boxers, while she was clad only in her skirt and bra, as she apparently decided to go without panties today. I could only gaze at her beauty, the way her hair flowed freely behind her, how her chest was heaving as she tried to catch her breath, of the sheer love, lust, and devotion I could see in her eyes.

I gave into the foreign instincts completely, allowing my body to be controlled by an unseen force as I grabbed her and spun her so that I was now over her, as she stared up at me with clear need. My hands started to roam her body, feeling every nook and cranny as she let out quite moans due to my ministrations.

A hand slipped under her bra, cupping her chest as she let out a small gasp of pleasure, and started to play with the hard nub I found there. My other hand went lower, caressing her body as I trailed down, until eventually finding a small gushing slit. I cut off her coming moan with a kiss as I started to slowly insert a singular finger into her, granting her immense pleasure as I knew exactly where to touch for maximum effect.

I don't know how long I spent simply worshiping her body, feeling every part of her writhe under my careful ministrations. By the time I had finished she was a quivering mess, the bed we were on thoroughly soaked by her. I slowly separated from her, and finally allowing my dick which had become painfully hard free. Rose, finally recovering enough to look at me, simply stared at it with a burning intensity before looking at me and giving a quiet 'please'. I couldn't deny her. Removing her bra and lifting her skirt I slowly entered her causing her to start moaning once again, and it was all I could do to not release right away as I felt just how tight she was.

Every little bit that entered her sent waves of pleasure through the both of us, until finally I felt myself hit a barrier, and despite how much I wanted to keep going I stopped, hands fumbling to the side and finally managing to grab what I was looking for. A quick wave of my wand and a muttered spell and now she wouldn't feel pain from what I was about to do.

"Are you ready?"

A simple question, one that she answered immediately by grabbing me and slamming me into her all at once, filling her completely. She let out a howl as she violently came, spasming on my dick and it took everything I had not to just follow suit. I felt her legs wrap around me and kept me buried inside her as I once again claimed her mouth for myself, my hands mauling her bountiful chest. As she was recovering from what was probably the first orgasm she ever experienced, I managed to slowly pull out of her until only my tip was left, causing her to start letting out little whines of displeasure.

They were quickly replaced by loud moaning as I proceeded to slam back into her, enjoying the heat and tightness of her virgin hole. I started to slowly thrust into her, increasing my speed as she was begging me to go faster, to pound her harder. Soon all that was coming out of her mouth was her mangled attempts to scream my name as I made her cum again and again. Eventually though I couldn't hold back any longer and with a last forceful thrust, planted myself as deep as I could in her, before painting her insides white. She let out a deafening scream and experienced her largest orgasm yet.

Still rock hard inside her, feeling that I could go on for as long as I wanted, I proceeded to do exactly that. After all, I had until Monday to claim every part of her, and I planned on doing exactly that.
