PROLOGUE: Your mentor initiates you to anal sex before sending you off on your quest.

"It is time.”

Her heavy hair fell in dark curls along her back as she stared out at the dark, curling sky.

"Time?" you echoed.

A presage of storm hung in the air. At once calm and alert, you glanced at your bowl of bark broth, in which herbs and leaves floated in a loose circle. A single chip of bark floated outside of it.

The realization split your mind as lightning cracks a silent sky, thunder rumbling in your bones in the aftermath. Ever since you were a child, Segora had alluded to the day when you would leave to go on your own quest; this journey was "indispensable to the achievement of your fullest potential", as she put it.

She turned to meet your gaze. In this instant of knowing, the one question she had never answered hung between you.

"I've taught you everything I know about magic," she said. “Except—"

"Sexual transference," you finished.

The shadow of a smile flitted across her eyes.

"Eager, are we?"

"I want to know… But I'm not sure I'm ready to leave you.”

"The scared boy still clings to the man... Good. Carry him with you. Listen to him. He will keep your strongest impulses in check. But, for now,” she said, closing the wooden door of the hut, “shush him.”

She walked over to you, shrugging off of her druidic vest so casually you would think there was nothing unusual there.

"W-what are you…”

The sight of her smooth tan skin had an almost hypnotic effect; her glorious breasts, her toned belly, her trimmed pussy, her long, long legs... The ageless druidess was the only family you'd ever known, like a surrogate mother and sister to you; as wise as she was playful, as beautiful as she was wild, as distant as she was here. You had never seen her naked before.

Even though you knew her to be almost a hundred years old, she looked like humans looked in their thirties: mages often lived to see two centuries, and most of this time, they would look the way they had when their bodies reached adulthood.

“Get naked with me,” she said softly.

Uncertain yet aroused beyond measure, you stood up and started to undress.

“In your readings, have you learned anything about the source of your father's power?” she asked, walking around the table to you.

You had never mentioned your research to Segora—but you found her question didn't surprise you.

“Not much more than what you told me,” you said, breathless.

Your tunic bunched up at your feet.

“He found a way to grow his power beyond what anyone had ever achieved," you continued, "and he became one of the most feared men on the face of Eratheal.”

In the last few years, you and Segora had passed by many towns, but only four cities big enough to deserve a library. Making the most of scarce precious time, you had come up with excuses to abscond and read everything you could find about the darkest, evilest mage of remembered times, the one who had had the five realms trembling and uniting for the first time in history to defeat him. Aside from various accounts of the plights and corruption he’d inflicted on the realms, there was lots of speculation as to the source of his power—but no definitive answer.

The naked druidess stepped in front of you, raising an eyebrow. She smelled of sex, wildness and magic.

“Any hypothesis?,” she asked.

“Well… if I read between the lines… I’m gonna take a wild guess and say it had something to do with sex?”

Segora smirked. She glanced at your engorged manhood, straining against the fabric of your underwear, and pressed a gentle hand against your chest. You let yourself fall back onto your chair.

"When mages have sex," she said, "it moves their well of magic. Unless the willpower of the mage is iron-strong, it can have devastating consequences.”

This you knew: it was the reason Segora had forever prohibited you from masturbating. She had warned you early on of the incredible hold sexual desire could have over you, and how giving in to it would waste your magical potential. Ever since the awakening of your sexual desire as a teen, you had felt surges of magic pulsing in your blood, a tension that grew stronger every day, for years, the need for release, and yet you had never waned, until the **** of the magic coursing through you was almost indistinguishable from the stirrings of your libido.

Segora melted down to her knees before you.

“Your father found a way to use sex magic in ways no one thought possible nor have been able to replicate. We’re still unsure how he did it, but I... some of us believe you could be the key to unlocking his secrets.”

"Some of... who?"

Her hands cupped your kneed and parted them. Then, she scooched in between them.

"Hmm?" she replied, coyly.

Her face came dangerously close to your tenting manhood.

"You said..." you tried to remember, but her fingers brushed your thighs, clawing lovingly, climbing up...

"You inherited a lot from your father... You might be our best chance at dismantling the remainder of his influence on Eratheal. If you can keep showing... that amazing willpower...”

Your eyes were on her, and hers were on the shape your cock. She fondled you through your underwear, and your breath caught in your throat. You were suspended on her touch, on her eyes, and on her lips. Her finger traced the outline of your cock through your underwear.

“Very few men make it this far in life without... succumbing... to the need for release... and wasting their seed... You've done good. We have...”

Her hand snaked into the thigh opening of your undergarment and wrapped around you. Your mouth opened—but no sound escaped. Your whole being clung to the moment, **** to prolong it.

“Breathe... Good.You’ve grown into a very powerful mage, Magnus. Your abstinence has kept your well of magic intact throughout the most crucial phase of your development. Now that your aura has settled... your well of magic brims with more potential than I've ever seen."

She licked her lips.

"But we haven't tapped into your most potent gift. Sexual transference is the most dangerous form of magic. It caused the downfall of countless power-hungry mages. But it's one your father excelled at, and one you have a special predisposition for.”

"Mm-hm..."

At some point while she talked, her hand had started moving up and down your hardness in a mesmerizing, sensuous motion, and it was all you could do to register her words.

"This is what you wanted, Magnus. Are you ready?"

You nodded dumbly.

She whispered something and blew on your crotch: your underwear immediately dissipated into dust, revealing the lewd sight of her hand coaxing your stone-hard erection.

"Segora..."

She moved her face to your manhood, nibbled the side of it, then pressed it to her cheek.

"Yes?"

She licked your whole length, staring into your eyes. You stared back in awe.

She slapped your length gently across her cheek, as if to better feel how hard and hot you were, and licked you some more. Her hand lathered up her saliva. Reality itself shimmered. Your bowl of bark broth started bubbling on the table, and your cock throbbed dangerously in her soft grip.

"Huh-unh," she warned, playful. "Not yet...”

Her hand motion slowed, and she closed her eyes. The familiar flicker of her magic alerted you just as frost appeared over her hand; her skin cooled around your burning erection. You gasped, the rising tension somehow halted. She held your pulsating cock in her magically icy hand, unmoving, and spoke with the authority you had come to expect from your mentor.

“Can you feel the surge in your aura? Our power swells when we engage in sex, and the excess seeks an escape. It becomes a craving. I can feel the power about to rush out of you. But have sex heedlessly, let lust control you, and your magic will become unwieldy. Your power will slip out of your grasp. Many mages fail to control their urges and thus riddle themselves with magical leaks.”

With that, she gave a gentle, agonizing tug on your erect cock and let it slip out of her freezing grasp.

"Aahh..."

"I know controlling yourself this long hasn't been easy..." she said. "But it was the best way to prepare you for what comes next.”

You gulped, overwhelmed by the new craving. Segora stood up, bringing her glistening pussy into view.

"See?"

She touched it, and her fingers glistened with juices.

"Almost a century roaming this land.... and still my pussy salivates for your cock."

She licked her juices off her hand.

"Lust assails us all. But... if I were to ride you right now... if I were to let you... lose yourself inside my pleasure-hungry hole..."

—her cheeks flushed, and you were suddenly certain that the same wild desire coursed through both of you—

"...you would be gifting me some of your magical potential," she finished. "That form of sexual transference is how most common folks have sex. It mingles the auras of the lovers in a powerful way; it can create life. But for us mages, it means our magical wells pour into each other. They usually even out. Since your well is bigger than mine... Bigger than most… Such an act would benefit me and leave you weakened, your power diluted. Magnus, you aren't likely to find anyone that matches your power.”

You nodded, taking in all the information. Despite Segora's frosty trick and her eerie warnings, this was the sexiest situation you had ever been in; you were still naked, and your cock was still standing rock hard, begging for attention. Segora rubbed her pussy again, but withdrew her hand quickly and dropped back to her knees.

"Even now," she continued, "part of me longs to taste you. I know I could taste… your power… I could… I could bury you in my mouth… until your potent seed fills me…"

You had never seen her like this. A new hunger played across her face... The same hunger that stirred in you. She brought her face close to your hardness, slowly. She opened her mouth, gauging your reaction... What did she just say? Something about... parting with a portion of your magic?

Her tongue coaxed you from root to head in a long, lavish motion. She moaned with you, even as your mind warned you to stop her. You didn’t want to give away your magic, did you?

But in this moment, your sex-starved body was hers. She had raised you, taught you everything you knew about… everything. You owed her your power; if she wanted to collect payment now, who were you to refuse her?

Her tongue left you. She pulled her head back and brought her soothing cold hand back to the base of your cock.

"Mmh!..."

"Sshh..."

Locking eyes with you, she slowed her her breathing, and you followed suit, syncing with her, falling seamlessly into a meditation technique you had done together many times—except for her massaging your cock... As her breathing calmed, so did yours, and you found a new balance on the razor's edge, between the peace of your mind and the edging of your body. Once you settled in the rhythm, she spoke again:

"This was just to give you a taste of what's out there... If even I feel the pull of your sexual aura, others will, too. And you, young mage, will have to be strong. Many, many creatures feed on sexual energy. Magical leeches will flock to you during your travels. They can sense your magic, as I can, and they would suck it out of you through their hungry mouths... or their salivating pussies. They will offer you ecstasy and steal your power from you.”

Her hands left you; you panted, feeling both relieved and anguished at the sudden lack of sensation. She stood up.

“To keep your magical integrity, you will need to choose carefully how to expand your sexual energy. You must tame your lust and that of others. Sometimes, it will be a battle of wills. Today,” she smiled,“you would have lost, making me stronger. But for this final lesson, I will yield to you. Consider it a parting gift.”

She sashayed to the little chest next to her bed and recovered a flask made of purple glass. Before your eager eyes, she uncorked it and poured an oily substance over her hand. Soon, your eyes rolled back into your head as the delicious sensation of her touch returned, made slippery with the oil she rubbed all over your erection.

“Oh wow…" she chuckled. "You are totally at my mercy, aren’t you?”

She gulped, and for the first time you noticed the shortness of her breath.

“To grow your well of magic,” she continued, urgency creeping up in her voice, “you must make your sexual partners submit to you. Own both your pleasure and theirs. Let them relinquish their body and their will, tipping the balance of sexual transference fully in your favour. Remember that, Magnus. You must lead them into a state of subservient satisfaction, where their pleasure is beholden to yours. The most potent way for a mage to do so is to fuck them through their most **** orifice.”

She turned around, presenting her perky, beautifully taut and round butt to you. A pink jewel shone between her tan-skinned cheeks. Your cock throbbed again as she peeked over her shoulder at you.

"Now, Magnus, would you please remove this jewelled wand from my ass?"
