Violet Enacts her idea first.

Sliding another book into place on the shelf, your fingertips buzzed as if full of electricity, pulsing with the power they held that could upend the world and had done exactly that.

You shudder at the memory of the haunting crimson dawn sky. That gave you a healthy respect for the power at your fingertips.

Which really just made you want to use it more, it made the notebook safely tucked away in your messenger bag you’d brought it in then as an added protection measure you’d written.

‘For everyone apart from myself they cannot consciously perceive the notebook, only subconsciously do acknowledge the notebook existence and treat it with care and seek to return it to me.’

But your back felt scalding hot on your side as if inside a sun radiating temptation was inside it.

That temptation was why you were putting books back into their places instead of hanging around the desks reading even though you didn’t have to work a single second again, as you have written.

‘All of my necessary work will handle itself and complete without my input, though I can work as normal whenever I want. All onlookers don’t perceive this and simply think and treat it as if I am working as normal, if they see me clearly slacking off or absent all day.’

You wrote it down as you had a strong ‘suspicion’ you’d soon be preoccupied with other matters than work during work hours. Sure, you could have left the reactions up to the book as no one would have thought it unusual. But, you wanted this as something completely unacknowledged without further consequence, out of sight, out of mind for everyone.

Like your sisters new hobby of camping because of their powers. You’d been looking through their social media finding Tsunade and Violet had tons of camping pictures. Many of them were Tsunade grinning ear to ear while in the background of many of them in her own gloom was Violet looking miserable, though there were enough of her enjoying herself that it was clear she liked those trips.

Going back further was a trippy experience as you saw on your moms profiles old pictures of you and your sisters as kids.

Seeing a kid Tsunade and younger Violet beside your younger self was strange and exhilarating. Pictures you long remembered with different faces while weird was expected, however the pictures of cherished memories being completely different reflecting Tsunade’s and Violet’s personalities spun your head a bit.

Letting out a breath you shook those thoughts from your mind as you your trailed your fingers over the spines of the books, it was mostly historical books.

Another book or two couldn’t hurt? You’d spent your morning reading them for inspiration along with fiction, fantasy and sci-fi books, ravenously pouring over historical oddities and the fantastical worlds contained in their pages for ideas.

They were wellsprings of inspiration serving as fertile grounds for ideas of exotic changes to ‘spice’ up things around the school and world, to the ambitious desire to outdo Genghis Khan prolific virility beating out his record of 16 million descendants.

Your cheeks tugged at your face as you couldn’t help but feel warmer at your lustful ideas, all the while in a school filled with hundreds of nubile young women who could become your harem with a single sentence.

To slowly corrupt or transform a house of learning into a campus of lechery dedicated for the sole purpose of raising and educating the finest concubines to serve you.

In your pants your cock hardened as you started to hurry a little more to finish and use one of your ideas. The ringing of the bell reminded everyone of ushering in the next period was a dull sound as you place the last book you had in its place.

Stretching among the tall bookcases of the library, your pants tugging down to pitch a noticeable tent. You looked around cautiously your gaze sweeping the empty aisle as you heard the soft voices of girls wanting to spend their free period in the library.

For a moment you thought you heard something, but quickly dismiss it as there’s no one else to be seen.

Before you could adjust your pants to hide your arousal, a source of warmth enveloped your back with two circles of blazing heat pulsing with a racing heartbeat. On your crotch you felt unseen hands grabbed your cock while a hot breath swept along your neck as your invisible assailant rested their chin on your shoulder.

“Violet?” You quietly groan as your pants are unzipped and the invisible smooth hands quickly wrap themselves around your rod twitched powerfully as you realized that to be completely invisible she must be completely naked sending a thrill down your spine.

“Hey bro, I uh wanted to see you.” Violet whispered with trembling fright into your ear holding you tighter, pancaking her modest tits in your back making her embarrassment and fear clear, yet she didn’t relent in her incestuous act.

Reaching back you find her side of bare skin and slide your hand down her body to her ass cupping it before groping her naked booty, confirming she was stark naked earning a soft moan in your ear that sent tingles of excitement through your body.

“Must have really wanted to if your running around naked to see your ‘big’ brother work.”

Violet swallowed as her hands clenched tighter around your girthy manhood. “Yeah, big.” She lustfully repeated the word.

Below your belt, her hands squeezed sliding down your pole, she went hand over once one hit the root of your shaft keeping you in an endless tunnel of pleasure you pump your hips into. Her repeating strokes building a sweltering heat in your body making it harder to breath as you could see how her hands squeezed your cock.

Straightening up you basked in your sisters perversion, the intermingling of incestuous lust and created belief of its necessity had them both abusing their powers to fuck in dangerous circumstance.

“Uhm, the fantasy section is just down this row or the next.” Naomi’s quiet voice pierced the silence of the library made you burst into a cold sweat and Violet’s breath hitching.

Your heart clenched in terror even as thrill sucked the air from your lungs. Violet needily whimpered in your ear, the danger of being caught seemily driving her wild with her hands speeding up their stroking as you looked to either side to see where Naomi’s had come from.

“Yup! Here it is!” A bubbly voice echoed over from the row over as your eyes found nothing which loosened the tight wires of fear and your cock throbbed at the excitement.

Their voices had brought that danger to the forefront of both of your minds. But, you weren’t going to give up this pleasure or heart racing thrill.

“Violet we need to move or we’re going to get caught. The front desk.” You whisper to her muffled sound of agreement.

Breaking part was a frantic flurry of action as you turned hands flailing all over her invisible naked body, grabbing her tits, hips and ass as you searched for her pussy her preventing her from leaving you behind, your finger drifted over the solid invisible barrier in the air of her soft skin, following the curves of her body to her sopping wet sex.

Your fingertips stroked her fold letting you line up your cock with Violet’s unseen entrance.

“Are you crazy? Isn’t this worse?” Violet fearfully hissed, however her actions said otherwise as she wrapped her arms around your neck readying herself for your plan.

Touching your tip to her leaking womanhood that drooled her molten arousal down your cock.

“Well, do you think you can stay quiet.” You asked as you readied to thrust in.

There was a pause making you wish you could see her face. “Yes.” She answered unsure.

“Good en-” You thrust upward spearing into Violet hot clinging depths without any resistance. Sheathed inside her, it would look to anyone else as if your cock was simply freely standing tall glistening from its wetness, but you could see in full detail the way her inner-walls clenched like a vice around your cock in heavenly pleasure. “-ough!”

“Mrhp!” Violet quiet strangled gasp was all she made as she locked her legs around your waist supporting her impalement on your cock, her hot body clung to your front as her weight and gravity kept me buried to the hilt in her wet snatch.

Squatting down Violet wobbled on your cock, breathily groaning in your ear as you grabbed the plastic bin you’d carried the books you’d been putting away, lifting you pulled it against Violet’s butt covering your free floating cock.

Standing up the motion carries into Violet bouncing her booty on your crotch stirring her insides with your cock causing her to hotly gasp, sending her warm breath across your neck.

The pleasure intensifies as each step you take jostles and bounces Violet on your cock as you leave the row, your strained ears can make out the near silent wet sounds of your unintended thrusting that chips away at your stamina.

Reaching the end your sweating trying your best to look as if you aren’t fucking your invisible sister, only to your dismay and soaring excitement to come face to face with Naomi in her oversized sweater.

“Oh, Mister Haverty!” Naomi blinked in surprise and addressing you as always so over formally. “Are you ok? You’re looking very hot.” She asked with genuine concern marring her delicate oriental features.

Plastering your best friendly smile over your excitement from the sound of Violet breathy silent drawn out moan of pure carnal desire.

“I was just running around putting everything back in its place, nothing big.” You spin the exaggeration as you pant through the sentence.

Violet however had other ideas or was **** to continue as she pulled herself up using your shoulder and dropped herself down fucking herself on your cock as you spoke with your coworker/boss. Your face twitched and you took a harsh breath from the fiery thrill blooming in your body and your balls begging to blow their load.

Nodding Naomi looked at you with her beautiful eyes filled with worry. “Um, well you don’t need to work so hard. You always get everything done, I don’t know what I’d do if you hurt yourself.”

“Ha-ha! It’s nothing, I’ll just be taking a break at the desk alright?” You say, your breathing growing more labored as Violet plumps her depths with wet squishing sounds you swear are too loud no matter what she thinks and you cover by clearing your throat as you careful walk around Naomi keeping the plastic bin between you.

Naomi gently nodded again. “Oh, don’t let me keep you from it.” She hurriedly said freeing you from the conversation.

It’s a blessing that the study tables weren’t between you and the main desk as you briskly walk, the hurried motions sending Violet wildly bouncing on your prick turning it into a race to your chair before you cum.

You almost slide around the corner to the main desk making your cock press into one velvety side of Violet’s pussy. Making it to your chair you collapse onto it, your knees too weak from pleasure to support yours and Violet’s weight that brought her plummeting down your shaft far enough to kiss her cervix with your cockhead.

That was the final straw as you lock your jaw shut restraining your groan as you climax. Looking down you get to see your cum spray all over Violet’s inner-walls for a split moment before it turns invisible as your cum floods her, becoming apart of her fertile young pussy.

Violet sensually gasps and moans in stealthy sounds as she climaxes, your cock visibly clenched by her pussy’s constriction as it milks more cum from your balls, who are happy to rise to the challenge to fill her up spraying several more thick ropes of cum inside her.

Reaching its zenith it tips and you come crashing down exhausted as you enjoy the afterglow. Your soften cock still held straight in the ‘air’ inside your sisters cum lubed vagina.

Violet presses her soft lips on yours that you clumsily return to the invisible woman who hugs you as you kiss.

Coming off she sighed content. “I love you.” She whispered before her weight left you leaving you to put your cock away tired but feeling amazing.

Grinning you folded your hands on your head. "Love you too." You say, not sure if she's close enough to hear the soft words.
