Greta’s inner sense of masculinity screamed in protest of the acts he performed upon the frustratingly attractive patron.  How did succubi function with such potent and unruly feelings of lust consuming their every thought and action?  Regardless, it didn’t matter.  Veilmont’s hot, steamy seed coated her mouth and flowed down her throat, her body glowing with wisps of crimson aura as a sense of complete invigoration overwhelmed her.

“Mmmmm…”  Greta couldn’t contain a moan of pure delight and pleasure, her body trembling and overflowing with mana.  Veilmont’s low grunts and moans only fueled her lust as she pulled back while sucking up every last drop of semen. ‘So-- so damn good…’ she purred, her cheeks flushing red as her actions sunk in.

Veilmont fell back onto the couch, his legs spread as he panted, his cock still twitching as the erection faded away.  “That-- was amazing,” Veilmont smirked.  “You’re a natural cock sucker; you know that?”

“I…”  Greta tried to speak, but her loins burned with unfathomable sexual need.  “I don’t know what came over me,” she squeaked, not noticing the more potent pheromones filling the air as they secreted from her sweat.  Even now, she desired nothing more than to accept her patron’s thick shaft into the aching hole seated at her vulva’s base.  Regardless of her identity as a manly, hardened mercenary, she found herself unable to fight the ever-growing hunger within.

“It’s instinct, my dear,” Veilmont replied, his breath rate finally falling under control.  Despite his experience, it was hard to resist the allure of even novice succubi.  “And I urge you to keep following it.”

Greta opened her mouth to protest, but no words came out.  Instead, a small amount of drool dribbled from her mouth’s corner, her eyes once more locking onto Veilmont’s dark shaft as it gradually sprung to life once more.  In a matter of seconds, he was rock hard.  Wholly mesmerized, she stepped forward with a sultray gait, her instincts taking control of her every action.  Gareth was pushed into the back of her mind.  It wasn’t as if she was a completely different person, or that she lost her memories, but feed mode blotted out all reason.

“Look what your pheromones did…  I’m hard already, and I’m completely under yoru spell, Miss Greta,” Veilmont teased, his body shuddering in anticipation as his penis twitched and a bead of precum emerged from the tip.

“Mmmm-- you’re so big, though…”  Greta said with worry that was more akin to an adorable, feminine pout. ‘I shouldn’t-- but the trial…’ Not only were her primal desires ur ing her forward, but the original goal of passing the trial could be more easily obtained by showing Veilmont the time of his life. ‘Will he fit?’ She mused with mild embarrassment, recalling the sensation of laying an egg.

“I am sure you can take it,” the man curtly replied, beginning to pant.

It was her duty to pass the trial, and to do so, she needed to succumb to her desires and please the beacon of masculinity sitting before her.  HIs dark skin, his glistening scales,  his musky scent and muscles-- all of it caused her loins to quiver in desperate need.

Without thinking, she stepped right in front of the sitting male and grabbed his shoulders before straddling his lap.  She lowered her body slowly, feeling the head of his erection press through her inner labia. ‘I-- I shouldn’t-- I can’t bed with a man-- but I have to…’ She bit her lip and trembled, stopping her descent as her breathing turned into labored pants.  She could pull away; the head had only just begun to part her feminine flower.  It wasn’t too late to back out and refuse the sexual encounter.

As she tried to reason with herself, she unconsciously pushed her hips down.  Her eyes suddenly widened as the head of Veilmont’s penis pushed into her vagina and inched upward. ‘W-- wait, I was thinking-- I-- ooooh…’  Her pupils dilated as a fuzzy, euphoric warmth enveloped her.  She leaned forward, pressing her breasts against her patron as her hips lowered, spreading her tight pussy apart and causing her to let out a string of purrs and moans.  It felt so fucking good already.  Her vaginal walls spasmed and contracted, massaging Veimont’s cock as she fully enveloped him to the base.  “Ahhhh!”  She cried out as Veilmont grunted and moaned himself, placing his hands on her hips.

Greta leaned heavily into his lips, forcing her tongue into his mouth as she lifted her hips and pushed down again, feeling the impossibly large, throbbing member spread her to the utmost limit.  There was no pain of any kind; every sensation within her throbbing womanhood-- no, within her entire body, was one of pure bliss.  Was this what sex as a woman felt like?  Her tail flicked wildly as she kissed and nipped the man, taking in his musty, masculine flavor and fueling her lust.  Her sexual encounters as a man paled vastly in comparison to the wonders of a lusty succubus body.

“Y-- You’re performing-- i--incrediby…”  Veilmont gasped as his penis throbbed and spasmed. He was at her mercy.

“I-- I am glad…”  Was all Greta could manage.  She thought of her sexuality as a man; that burining desire to press his cock into a tight, warm and moist hole-- the desire to impregnate.  Now, however, a very female Greta felt a vast emptiness that yearned to be filled.  Filled in a way only big, meaty cock could.

 They continued onward.  Every time Veilmont climaxed and shot his warm seed into Greta, she felt as if she were consuming an invigorating elixir through the walls of her pussy.  Her insides gladly acccepted Veilmont’s semen and mana, using it to feed her own power.  ‘I--  I shouldn’t enjoy this-- holy shit…  Fuck-- how do succubi deal with this lust?’ She briefly contemplated before another mind-numbing orgasm consumed her.  No matter where the trials took her, this night would stick with her for the rest of her life.

Lucilia and Nana sat together on the sofa of a secret staff lounge, gazing into the scrying mirror sat upon the coffee table.  Both had wide grins as they watched Greta finish up with Veilmont, having shown him an incredible night.

“She did such a good job!  Despite originally being male, she really devoted herself, heart and soul, to the trial.  What do you think?”  Lucilia asked her second in command.

Nana sat back and crossed one leg oer the other.  “She sucks cock like a veteran.  Veilmont appears quite satisfied with this most recent visit,” she chimed, the tip of her cat tail gently flicking about.

Lucilia sighed and waved her hand in front of the mirror, switching to both Chalce and Ingrid.  “All three of them have done well.  I never guaranteed they’d all be free to move onto the next trial at the same time, but none of them took the easy, slow road away from Succulence,” she purred, a wide grin spreading on her face as she brushed her tongue over one of her fangs.  “I’d love to keep them all forever, but, alas, I have a duty to Gaia,” she pouted, puffing her cheeks with an exaggerated huff.

Nana gently patted Lucilia’s back.  “There there.  I’m sure we’ll get some new girls to play with soon enough.”

Lucilia agreed, nodding in response.  “I suppose it’s only fair to give them one last challenge.  If they pass, I’ll move them on to the next trial.  Which one, though, I’m not completely sure.”

Nana hesitated, folding her hands in her lap as she thought about it. “I have an idea or two,” she chimed.

 Lucilia stretched and let out a yawn before facing Nana.  “We have time to think about it.  For now, I’m thinking that Orgy Night would be a perfect final challenge for those three.  What do you think, my dear?”

Nana’s ears perked excitedly as she nearly hopped in her seat.  “Oh!!  That’s a fantastic idea!!  Let’s do it!”

With that, the two succubi began their preparations, confident their three visitors would enjoy their final challenge at Succulence.

“I-- I can’t believe I’m really doing this,” Greta groaned, standing before an ornate wooden door.  Finally finding her nerve, she let herself into the room, still wearing the same skimpy outfit she was given during her first day of work.

She stepped into a large, dimly lit room with incense burners in each corner.  Beds, couches, and various cushions sat around the space, with some sections loosely segmented into separate lounges.  At the back center of the room, there was a bar counter with a petite, green-haired succubus happily humming and washing glasses.

“I guess I’m the first here…”  She glanced around cautiously before taking a seat on a couch near the room’s center.

Before long, two different doors opened and two women stepped in.  The first was a succubus with dark wings, tail, and horns.  She glanced around nervously, wearing an outfit much like Greta’s.  She had amber orange hair pulled into twintails, and eyes of the same color.  “Is-- is this the right place?”  She squeaked.

The other woman didn’t look remotely like a typical succubus.  She was a slime woman with a form shifting through shades of pink and purple.  A potent, succubus aura emanated from her translucent form, which had taken on an exaggerated hourglass shape with heaving, gelatinous tits.  “Oh!  I was so hoping I’d see you both again sometime soon,” she purred, stepping in as she glanced at the orange haired succubus to her left and then to Greta.

Greta blinked, looking between them as the realization suddenly hit.  “Chalce?  Ingrid?”  She asked, her cheeks flushing red.

After initial greetings, the three women sat on the same couch and made small talk about their time at Succulence.  Chalice stammered as she spoke, blushing furiously and shifting her eyes back and forth as she described an experience with a seven-foot-tall wolf man.  She provided vague details, but she showed signs of great arousal as she spoke.  Eventually, she had to stop speaking as she pressed her legs together, attempting to stop herself from getting even more aroused.

Ingrid had a different experience, but she showed nothing but eager excitement as she spoke.  She had been infused with succubus essence while retaining her slime-like form.  And, because of her unique abilities, she ended up servicing four clients simultaneously, using her deft manipulation of slime to please all parties involved, two of which happened to be women.

Greta was by far the most bashful, having very little desires to admit and discuss the fact fucking a male patron felt incredible.  “And, well…  I think I did a good job…  It’s not like I wanted to, but I couldn’t help it,” she muttered, fidgeting with her fingers.

“You don’t need to explain any more; it’s okay,” Ingrid warmly smiled.

"Yeah-- thanks…”  Greta sighed, not wanting to confess how excited her hormone-riddled succubus body was for orgy night.

After a short time, more succubi of various shapes and sizes entered, making small talk and giggling as they got comfortable, all seeming eager for the night ahead.  The group of three made small talk with the succubi who wished to converse with the new girls.

“I heard Veilmont was highly pleased with your abilities! He’s a top client of ours, so good work!”  A pink haired succubus purred.  

Greta flushed crimson.  “I-- I…  Thank you, I think,” she said sheepishly.  A small voice in her head asked when the patrons would get here, her body burning for more.

Eventually, a thus far unused door by the bar opened and people strode in, most looking  notexcited and nervous.  Most were men of varying races, but there were some women.  In total, fifteen showed up, the same as the number of available succubi.

Greta found herself eyeing a minotaur man wearing nothing but a loin cloth, his already erect cock poking through, showing off the head and half the shaft.  It was huge. How on earth would it fit?  She pushed her legs together, trying not to think about it.

Without warning, the room took on a bluish glow as the braizers burned brightly. Lucilia’s voice suddenly echoed for all to hear. “Thank you for joning us on orgy night, everyone!  Our lovely succubi and patrons have all been briefed on what to expect.  Please help yourself to complimentary drinks by courtesy of Miya, our lovely bartender for the evening!  Any attempt to harm our lovely succubi staff or force them into an unwilling situation will be met with immediate eviction and banning via magic!”

With that, the succubi and guests began to find one another and mingle, attempting to find partners for their first sexual interactions of the evening.

Greta sat awkwardly, her body trembling and screaming from the musty male fragrance wafting from the guests.  She planned on sitting here until someone approached, but Ingrid suddenly grabbed her hand and pulled her to her feet.  “Come on!  Let’s play with some guests together, okay?”  She grinned.

“W-- Wait, are you sure?”  Greta squealed as she found herself nearing the minotaur man and a couple of his friends, getting pulled along by Ingrid.  She turned back toward Chalce for support, but she had already wandered off toward a tall, lean male dark elf with handsome features and a throbbing erection beneath his shorts.

Ingrid and Greta approached the group in question, consisting of the minotaur man, a human barbarian of roughly the same height, and a shorter, but still tall and well-muscled man with deep red skin, horns, and other demonic features.  All three radiated pure masculinity.

Before Greta could open her mouth, Ingrid spoke for them.  “Hello!  Are you three gentlemen looking for a good time?”  She purred as the three men turned to inspect them with lust and contentment.
