Ch.3 Marianne the Succubus [FE3H CYOA]

[Ch.2 poll winner: option C - craving for sexy succubus clothes]

When Marianne’s weary eyes opened to the sight of Hilda’s bedroom, she thought she must still be dreaming. Oh, how she had dreamed of being back in this room again. But of course, after more of her consciousness returned to the waking world, she remembered this was no dream.

Only once she tried to lift the covers off herself did she realise her arm was barely responsive. Hilda was out like a light, but she still managed to cling to her girlfriend’s arm hard enough for it to fall asleep.

A weak smile graced Marianne’s lips. She had dearly missed Hilda needily holding her, anchoring her as if she could simply float away at any moment. Her nervous system, on the other hand, desired reprieve.

“I’m sorry honey, I need to get up now.” Marianne whispered almost silently, then leaned over to kiss Hilda’s forehead.

Hilda’s subconscious obliged, loosening her iron grip.

“Thank you, Hilda.”

As Marianne slid out of bed, the serene look on Hilda’s face washed away. On one hand, it was affirming to see how welcome her presence was on such a genuine, subconscious level; on the other, seeing her sleepy lover frown broke her heart.

And that was all before acknowledging her growing ability to sense the hearts of others. Looking into Hilda’s heart was easier than any other: what Marianne found within was love. Pure, desperate love, and a longing for her partner’s attention. Marianne practically melted.

“Ohhh, Hilda…” She cooed. “Come here honey, I’ve got you…”

The early riser slid back under the covers to embrace her dearly beloved. Without so much as a sigh, the sleeping woman immediately wrapped all her limbs around Marianne and held her tight.

“You poor, sweet thing… It’s alright, we’re together again~”

—

The day's journey back to the monastery went as surprisingly smooth as Marianne's trip the day before. It was nearly midnight by the time they returned, thanks to their morning spent sleeping in.

"It feels so weird being back here…" Hilda commented as Marianne guided Dorte back to his home in the stables.

"I feel much the same. I never realised how… ‘at home’ I felt here until we started using this as a base again."

"Yeah… We made some great memories here, didn't we!"

"We did, despite… everything."

"Have you made any more good ones while I've been gone? Ooh! Make any new girlfriends here?~" Hilda winked.

"Oh, um, n-no… I didn't…" Marianne turned away to hide her flushed face.

"Aww, why not? Ohhh, you're worried I'll be jealous, aren't you? It's ok Mari, I'm polyam too! I understaaand!" Hilda genuinely reassured her lover. "Come ooon, there's gotta be at least someone here you fancy! You've written about how much you care for everyone, and I know some of your old crushes have joined again as well~"

"W-well… hhhhh…" Marianne sighed. "There are a few people I'm interested in…"

"Eeee! Well? Don't just leave me hanging! Who are they?"

Marianne turned back to her girlfriend. Hilda hid it well, but she was jealous - though not in a possessive or controlling way - Marianne could feel it. Hilda truly was happy for and supportive of Marianne, but jealous at the same time. In her heart, what she wanted most was for Marianne to be happy, and yet… she feared Marianne would realise she didn’t need her anymore - that others could make her happier than she ever could.

"Hilda…" Marianne hugged her tight and whispered in her ear. "I will always love you, ok? Please… know how much I love you…"

"W-woah, where's this coming from?"

"I… I can feel your feelings, remember? I know what you’re feeling right now. You make me happier than I ever dreamed was possible… Please, please know… I want you to know that… you mean everything to me, Hilda.”

“Oh Mari… I love you too.” Hilda squeezed her lover with all her might, but this time, Marianne could withstand the almost superhuman strength. “Well, maybe we could start a polycule here together~”

Marianne giggled softly as she embraced her in return.

“Marianne, you’re back.” Byleth’s cool voice echoed from the stables’ entryway.

The couple broke off their hug and turned to face her.

“Professor? Is that you?” Hilda asked.

“Hello, Hilda. Welcome back.”

“Marianne was right, you haven’t changed a bit! Hee hee!”

“Would you care to share a meal? It’s late, you two must be hungry.”

“Sure thing! It’ll be just like when we were students!” Hilda smiled.

“Um, professor?” Marianne added. “Oh, um… nevermind, it can wait… But I have something I need to tell you after we eat. You both go on ahead, I’ll just finish up here.”

Marianne watched as the other two headed off, chatting as if nothing had changed in the past five years. It warmed her heart. She had feared that Hilda would be treated with suspicion upon joining their cause, but with the professor’s confidence, all others would quickly follow suit - save perhaps for Hubert, but he was suspicious of everyone.

Her body gave off her lilac glow in one short, faint pulse as a new urge coursed through her: an outfit. She needed a beautiful, tight, alluring set of clothes. Marianne desired to be eye candy to those she loved, and needed to be so as soon as possible!

Marianne's knees wobbled and a wet spot formed in her soft panties. She desperately clawed at her crotch through her dress in a futile attempt to sate her demonic hunger. Her breaths grew short and quick as mental images raced through her mind: turning on her lovers with her sexy succubus figure and form-fitting demonic garments; commanding her lovers to kiss her boots as she held them by a leash; sliding her gloved hands across her lovers' soft, toned, and muscly bodies; and perhaps even giving her lovers the chance to be her clothing…

A gentle whinny from Dorte snapped her out of her thoughts.

“Oh, ahem… Thank you, Dorte. You’re always looking out for me!” Marianne said, then gave her horsey friend a gentle pet. “I’ll see you again tomorrow, Dorte, don’t worry. Have a nice rest, you’ve earned it.”

With that, Marianne took a deep breath, did her best to compose herself, and hurried off to meet Hilda and Byleth in the mess hall.

—

When Marianne stepped through the door from the entrance hall, her libido returned with a vengeance. Another gentle pulse of light emanated from her body, bringing with it a renewed lust to model a sexy outfit for those she loved. It took all her strength not to return to fingering herself right there and then.

The professor and Hilda were already sharing a table at the other end of the otherwise-empty room. Three steamy bowls of soup sat on the tabletop as the pair patiently waited for Marianne to arrive.

With each wobbly step she took, Marianne’s distracting libido mounted. By the time she reached her friends, it was too late to go on like normal. She couldn’t hold back any longer.

A burst of light erupted from Marianne’s body as her modest dress and the rest of her clothes vanished into thin air. Her succubus crest materialised above her head, followed by rapid transformations in her body. In only a moment, Marianne regained her horns, her tail, her lilac hue, and her talons as she was forced back into her demonic form.

As this happened, Hilda’s eyes widened, her gaze drawn by her lover’s magical allure. Byleth, meanwhile, observed as stony-faced as ever.

Much to Marianne’s relief, replacement clothes formed around her - except these were like nothing she had ever worn before. A sleeveless, midnight-purple leather bodysuit wrapped itself around her glowing body. It featured a boob window that extended all the way down to her belly button, and flourished in an ornate little collar around her neck. As a pair of black leggings formed under the bodysuit, violet boots appeared and grew upwards. The boots tightly encapsulated her soft legs and lengthened into sexy leather thigh boots with modest three-inch heels. Next, Silky black opera gloves slid onto her lithe arms, followed by violet leather bracelets and a choker which matched the rest of her leather attire. A black gremory hat with accents of purple leather popped onto her head. A dark mesh veil sprouted from the back of the hat, shielding her hair and neck from view. Finally, threads of sparkly, bright violet silk appeared all around her and began to embroider themselves into a floral pattern on her leggings, gloves, and hat.

When Marianne stopped glowing, she instinctively stood with confidence. To her surprise, she didn’t feel like cowering away whatsoever. Instead, all she desired was the gaze of her lover.

“Oh my goddess, Mari, that outfit is STUNNING!” Hilda commented.

“Hmm, I suspected as much.” Byleth muttered, holding a hand to her chin. “It really is early days for you. You don’t even have your wings yet.”

“Professor? You’re not shocked or confused?” Marianne asked. “And… ‘Early days’? My ‘wings’?”

Byleth stood up and faced Marianne. “This is what you wanted to tell me, isn’t it?”

“Y-yes…”

“Ah. Well, I have something to tell you, too, but it will be easier to just show you.”

Byleth held a hand to her chest, bowed her head, and shut her eyes. Pitch black and shiny golden flames erupted at her feet, consuming her body in a swirl of light as the Crest of Flames appeared over her head. Only a second later, the flames and her crest vanished, revealing the person within.

Byleth was also a succubus!

A small, simple pair of horns protruded from her forehead and a thin tail tipped in a spearhead hovered around her. Byleth’s skin had turned an ashy, almost blueish grey colour, and her fingers bore their own razor-like claws. However, the most noticeable change was the pair of huge, demonic wings extending from her back. They were bat-like in shape and had a wingspan of about three metres! But inside, Byleth’s wings were a void, or portal, or some sort of optical illusion. Stars twinkled through her wings as magnificently as any hanging in the night sky!

Marianne stumbled back a step without averting her gaze, revealing another wonder of her professor’s succubus wings: the starry sky framed inside her moved stereoscopically with respect to the wings themselves. It was like there was a whole universe in there, and as far as Marianne knew, there really could be!

Both Hilda and Marianne silently wondered if this had anything to do with Byleth’s nickname of sorts, the ‘Ashen Demon’.

Without moving a muscle, Byleth summoned another wave of flames, both shadowy and golden. Her body vanished behind the bright - but surprisingly cold - fire, then emerged again in its human form.

“Don’t be afraid, Marianne. You’re like me. I’ll help you find your wings.”

Byleth reached out her hand, and after a moment of stunned silence, Marianne grabbed it with her own. Unable to hold back tears, Marianne practically leapt on her teacher for a big hug.

“Thank you, professor… Thank you!” Marianne sniffled.

“You’re welcome.” Byleth returned the hug. “For now though, let’s eat. You still need food and rest.”

With that, the pair joined Hilda at the table and enjoyed their meal together, almost as if it were just like old times.
