Festering Desire

It was late afternoon at the end of school. By this hour, the heat built up during the bright sunny day had already settled down from its peak, the gentle breezes carrying the sounds of cicadas herald the coming of summer. While other students congregated by the school entrance, Leo walked through the empty courtyard alone, making his way to the back of the gym.

The love letter from Lilith this morning politely requested him to meet up at the equipment storage room after school. Apparently, the gym's warehouse in school somehow had a sacred reputation of being a dating spot in this world. If there was a place one prefers to convey his or her love to another, or any other couple related endeavors, a hidden and well isolated storage room far away from the watch of civilization was the perfect location to commit a crime.

Perhaps it was obvious to imagine the purpose of this meeting; however, Leo highly doubted Lilith's intention was for her to simply confess her love. The girl was usually very blunt and confident, if she wanted to meet after school, it would have been simple to invite Leo straight to her home.

They had been friends for many years thanks to his late mother. He could tell Lilith's reactions today were fairly strange. For a girl that always shows off as much skin as her, she simply doesn't get shy too easily.

But of course, the letter had a bunch of other stuff and cute drawing of hearts insinuating it's a love proposal, but those are just trivial details that Leo barely scanned through. Classic maidenless behavior, do not try this at home.

The boy entered the storage room that was the size of a rather large shack. Its interior was dark, with a single ray of light beaming through a small window. Only a few strips of light landed on the figure waiting in the dark. They illuminated the endowed portions of the figure's assets while hiding the rest in shadows. The contrast of shades produced a mysterious vibe and an alluring ambient.

With time frozen in place for that brief moment, it seemed like it was the perfect time for Lilith to make her confession. But the boy simply turned on the lights, ruining the buildup of atmosphere.

"..."

"Leo, how do you feel about me? Perhaps, do you see me as someone more than a friend?" Lilith asked while playing with her fingers.

Leo briefly closed his eyes and revealed a faint smile. He walked forward and gently placed his hand on Lilith's cheek.

"Of course, I already see you as a family." That was pretty smooth...maybe.

Lilith's expression brightened up in red and grabbed Leo's hand to place it on her chest.

"I am extremely happy. Can you feel it? My heart is beating so fast. Po-don Po-don it bounces." The girl let the hand sink further into her deep valley.

The honest answer would be no, Leo thought. There were too many layers of fat for him to feel any vibration, but the soft sensation did feel heavenly.

Fortunately, Lilith then pressed her overflowing asset against his chest and tightly hugged the boy before he needed to answer. The girl was greedily sniffing the scent on Leo's broad chest.

"The smell! It got even stronger, so tender, so exquisite."

Leo did not resist but was slightly shocked by the perverted act; her legs were locked in with his and he could feel his upper leg pressing into the warmth inside the skirt. While she continued to tumble within his embrace,he noticed warm fluids from within the skirt were flowing down to his leg.

However, Leo managed to remain calm and was checking for any anomalies. Her Anima was slightly unstable, but still retained its purity and refinement, no trace of being possessed was found.

Suddenly, Lilith released the boy and took a few steps back. She grabbed the sensitive parts of her body with her own hands and heavily panted.

"Haa! I am sorry Leo. Hah! I can't hold back. I want it! I want it so bad!"

A pink aura began to form around Lilith, the girl had an ecstatic look on her face. Two curly horns were growing out of her head. She began to grow taller; the tight school uniform was digging into her skin. Her rear also began to develop in great proportion to her new height and a sizable portion escaped the cover of her skirt. The stretched panties formed a thin line within her buttock and could barely hide the two pink entrances.

And at the top, two cherry tips of her blooming melons were visible on the stretched fabric. Mr. Button finally gave out its last drawing strength and popped out with terrifying momentum, revealing her bare breasts with no bra underneath. Leo skillfully dodged the incoming projectile.

At last, with two adorable wings and a tail, Lilith was transformed from a pure overly endowed young maiden into a mature big sister with an explosive figure.

"Lilith, you are not human!? What are you?" Leo was in disbelief that his friend was a succubus demon straight up out of certain cultured animes that fall under the category H.

"Ah, I don't know if I count as human biologically. But why does it matter?" Lilith giggled and licked her lips.

Followed by a snap of fingers from the succubus, a runic circle appeared on the floor beneath Leo. In the next instance, the boy was tied down to a conveniently placed gym mattress by multiple blue strings of light. He was laying on all fours with his limbs spread out.

Leo thought it was careless of him. Lilith was known for her physical prowess as an awakened; he never expected her to be capable of such a sophisticated spell. However, he was in no rush to undo the binding. He wanted to see what she would do next. The boy still believed his pseudo-childhood friend won't bring him harm.

Lilith quickly crawled onto his body, pressing down her enormous soft pillows on the boy along the way. The girl stared down on Leo with fierce passion, panting heavily into his face. A passionate kiss naturally followed; she aggressively dug her tongue deep into his mouth, savoring the rich taste of high-quality Anima.

Guided by the techniques in the holy black bible, Leo was able to achieve pristine refinement of Anima normally unachievable by humans, or any other supernatural beings, with unique attributes of his own. His childhood friend had been resisting the urge for too long, and could no longer hold back after seeing Leo's refined Anima increase in quality day by day. With her keen succubus sense, Leo's concealment ability was rendered obsolete.

A certain burning sensation surprised the girl and diverted away her attention. It was the tip of a massive erection that formed an obscene bulge on his pants, rubbing the soft budding lips of Lilith's honey pot from beneath the fabric.

Lilith clenched her thighs against the oversized swell in response and had a mini orgasm. This was when the girl realized where the actual gold mine was hidden. She excitedly crawled back down to the obscene bulge and intoxicated herself with Leo's manly pheromone; it reeked the stench of highly refined Anima.

Freeing the beast from the constraints of fabric, the succubus was captivated by the majestic pillar and also enthralled by the dense concentration of Anima compressed within the bloated scrotums. Thick veins were populated over Leo's entire bulging mass, potent life force was flowing within them. The towering rod was beating with incredible power.

"This...! This is amaziiingg!! Leo, just what are you??" *Sniff Sniff* Lilith asked while staring viciously at her prey.

"Uhm? Shouldn't I be asking you the same?" Leo retorted, but his manhood was twitching in anticipation.

"Hehe. Please just let me take a little bit first, just a little...I will savor it, just a little is enough..." Someone with well-versed knowledge on Lilith's race would tremble in fear upon hearing those words, but will still die a happy man.

Wiping off the drool from her face; Lilith opened her mouth and revealed the soft pink texture of her naughty tongue covered in her own sticky saliva. Perhaps due to her racial talent, the girl gobbled up the swollen mushroom tip with ease and took in another few inches before it touched her throat. She grabbed the rest of the length with both hands and swirled the tongue around the tip.

Leo's size leaves little room for her tongue to maneuver, but the grinding of her teeth and the warm feeling of his tip being encompassed within the tender walls of her mouth easily brought him to the brink of climax. The boy felt complexed at the fact he was about to lose his virginity to the blowjob of his childhood friend.

All of the pressure from consuming supernatural entities had been pent up in saturation over the years. Once the trigger is lit, there will be unforeseeable chain reactions. The floodgate was finally breached under Lilith's aggressive attack and tremor can be felt within the swelling leviathan.

Small visible bumps began to travel along a certain length and Lilith's eyes widened from the forceful impact felt at her throat. Dense, viscous white seeds quickly filled the interior and expanded her cheeks. Soon, with few droplets escaping from her lips, for every glob reaching the tip of the towering rod, a bulge also traveled down along her throat. With a teary expression, the succubus finally received her long-anticipated meal.

Lilith couldn't fathom how much essence she just swallowed; it must have been at least half of a liter worth. Yet, more impressively, the colossus was still brimming with energy within her mouth and retained full form. Rather, the two orbs down below looked even angrier than before.

She slowly let go of the meaty gland with strings of thick cheese hanging down from her lips. Her mouth was unable to close while she erotically puffed out steamy fogs with thick aroma. Her eyes wandered off to the distant void as her mind was transcended by pleasure. A gentle warmth started to spread from her stomach, re-vitalizing every cell in her body.

However, just as Lilith was savoring the abundance of high-quality Anima, Leo's vast reserve of energies began to circulate through his veins at full speed. An adrenaline rushed over to his head and he broke the binding in an instant. The cultured cultivation technique from the grimoire was in full activation mode.

While Lilith still drowned in ecstasy, Leo stood up and grabbed her by the horns on her head. He hastily aimed the gargantuan rod and mercilessly thrusted its length down into her throat. The throbbing mass ignored all barriers including in the esophagus and was plunged into the very depth its length could offer.

Lilith had no time to be surprised as her mind blanked out at that very instance. Her eyes rolled back in shock while an abundance of white seeds were forced out from the rim of her lips.

The boy was suddenly taken over by lust, or more precisely, he was taken over by the new instinct he acquired from the grimoire's cultivation technique. A major side effect that he easily overlooked when reading the fine prints or simply did not understand its implications.

Locking down her head by holding the horns, Leo started to violate her throat with powerful thrusts. Lilith couldn't offer any resistance; if it wasn't for her superhuman body constitution, her life would have been in jeopardy. The obscene bulge that formed along with the movement of the leviathan inside her was an indication of the deepness that the boy reached.

But soon, Leo easily forfeited his second load of the day. It was just as rich and generous as the first serving and directly pumped into her stomach. Lilith slowly regained some of her senses in the middle of the discharge; she thought that Leo was finally done. The overwhelming volume was already too much for her body, his overabundance of concentrated Anima was intoxicating her very being.

Yet, near the end of the lengthy discharge, Lilith was gradually succumbing to fear. The bulky mass within her throat was not showing any signs of softening. It began to move again shortly. Temporarily overloaded with Anima, she could only helplessly look at Leo with her puppy eyes and beg for mercy. Leo's dominance almost made her feel like a disgrace to the succubi kind.
