Authors Note:
Warning! This chapter contains content of an explicit sexual nature. In that regard, if you find such material uncomfortable to read, I suggest that you skip ahead to the next chapter now. For those of you that elect to stay and are curious, the title of this chapter is taken from Pink Floyd's fourth album. Not only was the term, Ummagumma, slang for sex in Cambridge in the late 1960s, but like the album from which its name is derived, this chapter should be viewed as a bit of an experiment. I came up with the idea and, for lack of a better term, just ran with it. In the end, I am actually quite pleased with how it turned out. So, without further delay from me, enjoy.

Part Three: Their Secret
Chapter Four: Ummagumma
Stray beams of moonlight crept along the floor and up over the bumpy sheets that covered Kari Kamiya's bed. The bearer of light lay on her back beneath them, her knees raised and split, like the twin peaks of two mountains separated by a deep valley. Her pale blue pyjama trousers were bunched around her ankles and the matching jacket wide open to reveal the small mounds that were her breasts. Her eyes were closed and her mind focused on the image of her brother. His every metaphorical action mirrored by a touch from her own hands. A moan escaped from her lips as Tai lightly ran his index fingers in slow circles around her stiffening nipples. She gasped when thumbs and forefingers gently squeezed. In a firm grip, he took her breasts in his hands and began to knead them, like they were balls of dough. Her heart rate increased in tandem with his tempo and she could feel her breathing become more rapid. Ecstasy flooded through Kari and she arched her back as she let out an elongated moan. This attention to her breasts was almost too much to bear.

Across the hallway, inside his own bedroom, Tai lay beneath the covers of his own bed. After he had said goodnight to the physical incarnation of his sister, he had gone straight to his room, shut the door and stripped of his clothing. It had been a relief to finally be able to free his throbbing penis from the confines of his boxers and jeans. From his bottom desk drawer, he'd found a condom, ripped it open and used it to sheath his shaft. He intended to enjoy every moment of this and did not want to constrain himself with thoughts about making a mess.
Images of a naked Kari, her blazing hair glistening in an imaginary light filled his mind and for the first time, he welcomed her with open arms. Wrapping them around her slender frame he could feel the warmth between them. His entire body ached and he moaned softly at the contact between their bare skin. Using his own hand, he mimicked her strokes as she gently caressed his penis. A grin spread across his sister's face as she slithered down his body, extended her tongue and flicked one of his nipples with it. His free hand carried out her action and he groaned, "mmph."

Nipples hard like pinecones, Kari writhed under her sheets as her fingers pinched at them. Inside her head, Tai had slid downwards, taken one between his lips and sucked hard. She'd silently screamed in delight, her self-control hanging by a precarious thread. In an ironic twist of fate, the only danger was that Tai would hear her and give in to his own desires and turn fantasy into reality. While lust and libido would doubtlessly love every second of it, sense and psyche would probably have trouble processing it in the aftermath. It was one thing to allow your imagination to run wild, but something completely different to actually do it. And while she may be in love with Tai, Kari knew she was not ready to expose herself to him, or anyone for that matter. That aside, it did not stop her enjoying the creations of her own perverted mind.
After giving both breasts a thorough oral workout, her brother reached out and took both nipples between thumbs and forefingers. He twisted and teased, sending shockwaves up Kari's spine, as his tongue snaked its way between her cleavage, down her abdomen and towards her naval. He stopped briefly to plant some gentle kisses before continuing on his way south. A fingertip was the closest approximation she had as she traced a path through her neat pubic hair. A light touch told her that the night's ordeal had left her soaking. Inside her head, her brother's tongue flicked her clit at the same time her finger made contact.

Inside Tai's mind, all he could see was the bright orange of Kari's hair as he gazed down at her. One hand rubbed at his right nipple, while the left was tormented and teased by her teeth and tongue. A moan, far louder than he would have liked, escaped from his lips when his right-hand copied hers and tightened around his throbbing penis. Up and down he stroked in an even rhythm like he was stoking the embers of a fire, waiting for his sister's actions to allow him to ignite the furnace.
Kari's tongue circled his nipple one last time and then traced a path down his chest that caused him to tense. She lifted her head so he could gaze into those perfect reddish-brown orbs as she paused. The devilish grin spread across her face before she extended her tongue once more and licked the tip of his penis. In slow, deliberate movements, she circled around the head before running down the shaft to his balls. A series of gentle kisses were planted on each before she zig-zagged her way back to the summit. Lips puckered, Kari kissed the head of his penis with an exaggerated smooch, before opening just enough to allow him inside.

"Urgh," she exclaimed, as her brother lapped up her clitoris. Wave upon wave of pleasure crashed down upon Kari, showering her with an ecstasy that was truly divine. Each flick of his tongue was like a splash of red wine being added to the hot wok that was her sexual desire. The instant it hit the metaphorical metal, it erupted into a burst blue and orange flames. While in reality, it may just have been her own finger, it transpired that a saying she had once come across on the internet was indeed true; when it came to sex, the brain was king.
Imaginary Tai then moved lower. With ease, he slipped his tongue inside her opening and licked the upper region of her vagina; just managing to catch her g-spot. If there was a heaven beyond this, it could wait Kari thought as she swirled her finger around the outside of her vagina. The pleasure ramped up another notch. Her brother then raised his head, a droplet of her sweet nectar on his lips. He gave her a grin and shifted himself into position. Pressing her fingers over her entire area to simulate the feeling of her brothers erect penis rubbing up and down in her juices, Kari prepared herself for entry.

"Uhhh…" Tai called out as his metaphorical little sister bobbed her head up and down his long shaft. The urge to pop then and there almost overrode his self-control as he felt his pleasure ratchet up with each and every movement of her soft lips around his penis. When she lifted her head, his hand came loose. Licking her lips of his pre-cum she gave him a devilish smile and he knew what she wanted.
Slithering up his body, Kari rubbed her wet vagina against his erect penis. Arching her back, she brought herself upright so that she hovered above it. His body ached with the need for release, but like a champagne bottle that had been stripped of its foil and had the wire cage removed, he needed to wait until it was shaken before the cork could pop and the contents pour forth.
Taking his throbbing shaft in hand, Tai readied himself.

Tai and Kari's hips moved together and he slipped inside her, eliciting a cry of pleasure from both parties. Pressing further together, Tai moved deeper inside his sister, rubbing against her G-spot. Instinctively, both parties started thrusting. In sheer unadulterated ecstasy, the siblings felt pleasure wrack their bodies like it were strife in a cloud. With the results being no less electrifying.
"Mhhh, harder…"
"Ohhh, faster…"
They picked up the pace as Tai's penis reached as deep into Kari's vagina as it would go. With each and every thrust, their hips crashed together and separated in perfect harmony. Pleasure rolling of them both like drops of water off an awning. For the two siblings, nothing mattered except for the existence of them both in this moment.
"Argh!" Kari moaned out loud as the sensation of sheer bliss reached its zenith and threatened to tip her over the edge into orgasmic heaven.
"Urgh!" Tai cried out as the pressure in his penis reached a point that he could no longer contain.
"Tai!"
"Kari!"
The explosion that occurred in both siblings genitalia sent them soaring into a land of pure divine bliss. The feelings of release and pleasure so strong they overpowered all other thoughts.
In their respective bedrooms, Tai and Kari lay amidst their bedsheets, their limbs floppy and expressions of pure serenity plastered across their faces. That had been exactly what they had both needed.
