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

"It is time.”

Your mentor stood at the entrance of your little hut, staring at the greying sky, her heavy hair falling in dark curls along her back. The fatality in her tone awakened your prescient senses. As she had taught you, you seized the fleeting sensation—the Whisper of Destiny… You put down your spoon and peered into your bowl of bark broth: herbs and leaves formed a loose circle within the foggy concoction, and a piece of chipped bark floated outside it. A feeling of isolation rose inside you as you stared at it.

"Time?" you echoed.

Ever since Segora undertook your education in the magical arts, she’d alluded to the distant day when you would become a man and depart on your own quest; this culmination was "indispensable to the achievement of your fullest potential", as she put it. Even though more than a decade had passed, and you were now indeed a young man—and yes, it was true that your power now surpassed hers… Still, the realization split your mind as lightning cracked a silent sky, thunder rumbling in your bones in the aftermath. These last few idle weeks, going over old lessons... Had she been delaying this moment?

Segora 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, “you can shush him.”

As she walked over to you, she shrugged off of her druidic vest and let her trousers fall to the floor, disrobing so casually you would think there was nothing unusual there.

"W-what are you…” you trailed off, mouth agape.

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. 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...

“It is time," she repeated. "You see it too. We can’t hold on to innocence forever.”

Even though you knew her to be almost a hundred years old, she looked like humans looked in their thirties: druids were said to live up to two hundred years, and most of this time, they would look the way they had when their bodies reached adulthood.

“Get naked with me,” she said softly.

Her voice dissipated your thoughts. Uncertain yet aroused beyond measure, you stood up and started slipping out of your tunic, hands shaking. She smiled at your eagerness.

“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 the surprise at her knowing didn't register under the shock of the current circumstance.

“Not much more than what you told me,” you said, breathless, as your tunic bunched up at your feet. “He found a way to grow his power beyond what anyone had ever achieved, 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.

“Any hypothesis?,” she asked.

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

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

Your engorged manhood strained against the fabric of your underwear. Segora pressed a gentle hand against your chest, and you let yourself fall back onto your chair, staring up at her.

"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. Early on, she had warned you 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.

“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 as to how he did it, but I believe you could be the key to unlocking his secrets.”

Segora pushed your legs open and kneeled in between them. Her hand caressed your thigh, coming dangerously close to your tenting manhood.

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

Her finger traced the outline of your cock through your underwear, and it was all you could do to register her words.

“Your abstinence has kept your well of magic intact throughout the most crucial phase of your development. It’s allowed your power to grow without leakage. Now that your aura has settled, your well of magic brims with more potential than I've ever seen."

She licked her lips.

“Very few men make it this far in life without succumbing to the need for release and wasting their seed.”

Her supple hand snaked its way into the thigh opening of your undergarment and wrapped itself around you. Your mouth opened, but no sound escaped. Your whole body seemed to cling to the moment, **** to prolong it.

"Now. You’ve grown into a powerful, accomplished mage, but together we’ve reached the culmination of your innate abilities. The only way for you to grow past your current power class is to master the most dangerous form of magic, one that caused the downfall of countless power hungry mages. The one your father excelled at. Sexual transference.”

"Mm-hm..."

At some point while she talked, her hand had started moving up and down your hardness in a delicious, sensuous motion.

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

You nodded—for why use words?

She whispered "Dissipare" and blew some air on your crotch: your underwear immediately dissipated into dust, revealing the lewd sight of her smooth hand coaxing your bulging erection. She moved her face to your manhood and kissed the side of it. Then, she licked it and coaxed her saliva along the length of it, all the while staring in your eyes, studying the effects of her ministrations on you. You stared back in awe. She pressed her cheek against your length, as if to show you how big you were, and licked you some more, her saliva dribbling down and her hand lathering it up. It was too much. Your bowl of bark broth started bubbling on the table, and your cock throbbed dangerously in her soft grip. Your magical aura seemed about to burst.

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

Her hand motion slowed, and she closed her eyes. The familiar flicker of her magic alerted you to her doing just as frost appeared over her hand, her skin cooling rapidly around your burning erection. You gasped. The sensation wasn't unpleasant, but the sudden temperature change halted your rising sexual tension. 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 how much you want to let the power rush out of you. But have sex heedlessly, and you risk parting with a portion of your magic. Let lust control you, and your magic will become unwieldy, drifting from your grasp. Many mages fail to control their urges and thus have riddled 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.

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

You gulped, unable to respond, overwhelmed by a new craving. Segora stood up, bringing her glistening pussy into view. She brought her hand to it.

"See?" Her fingers glistened with juices. "Almost a century roaming this land, and still my pussy salivates for your cock. Lust assails all of us. But if I were to ride you right now, if you lost yourself inside my pleasure-hungry hole, you would be gifting me some of your magical potential. 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 mages, it means magical wells pour into each other. Since your well is bigger than mine, such an act would benefit me and leave you weakened, your power diluted. You aren't likely to find anyone that matches your power.”

You nodded, taking in all the information while trying to clear your thoughts. 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 eye's rested on it, and she kneeled in front of you again.

"Even now, part of me longs to bury you in my mouth until your potent seed fills me,” she said, almost to herself. "If I fed on your pleasure, I could grow my well of magic even more."

She brought her face close to you, gauging your reaction. Your mouth opened in anticipation. She proceeded to lick you from root to head in a quick, lavish motion. You shuddered in pleasure and moaned with her, 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.

"Segora..."

"Sshh..."

Locking eyes with you, she synced her breathing with yours, and you followed suit, falling seamlessly into a meditation technique you had done together many times: as her breathing calmed, so did yours, and you found a new balance between the peace of mind and the edging of your body. Once you settled in the rhythm of her breath and the rhythm of her hand’s motion on you, she spoke again in a calm voice:

"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 offered pussy. They will offer you ecstasy and steal your power from you.”

Her hand left you; you panted, feeling both relieved and anguished at the sudden lack of sensation.

“To keep your magical integrity, you will need to choose carefully how to expand your sexual energy. You will have to tame your lust and that of others. Sometimes, it will be a battle of will. 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 walked 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 erect cock.

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

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

“To grow your well of magic,” she continued, urgency creeping up in her voice, “you’ll have to 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. 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?"
