Mina sat behind the front desk of the Hideaway Inn, enjoying the peace and serenity that came from working the overnight shift. Working at a rundown hotel chain hadn't been one of her life goals, but she was confident she could persevere. 

“Mmmm…” She rubbed her eyes and yawned before resting her elbows on the counter, propping her face up. Her employer made her wear a nice uniform with a button-up blouse top and pencil skirt, likey to give patrons the illusion that they were staying somewhere upscale. Though, to be honest, she thought the outfit looked good on her.

She noticed her breasts chafing and grunted, picking at her bra strap. It wasn't the right time of the month for her period, so she wasn't sure why her breasts were so swollen and sensitive.  

Life wasn't all bad, though. Her job was straightforward and gave her time to browse the internet. She had also started seeing a male college graduate with a bright future. Both were in their early twenties and had their whole lives ahead of them.  She was also allowed to keep her long, fluffy black hair down.  Ponytails and buns weren’t her style.

Mina was incredibly picky with relationships and only dated those she could see herself marrying; she hadn't even slept with her new boyfriend after three months of dating.

She prided herself on being a chaste young woman but had been having more noticeable difficulties over the last few days. She would wake up in the middle of the night with her vulva throbbing in desperate need. When she pleasured herself, she marveled at how sensitive she had become.

After that first night of impassioned self-care, other changes set in. Men, in general, appealed to her more than ever before. She found herself seeking porn that let her fantasize about sucking and riding massive cock. She even caught herself daydreaming about some of the men who came in to get a hotel room.  

As if on cue, the front door opened, and a tall, well-built man walked into the building. She immediately noticed the muscular physique outlined beneath his well-fitted tee. He had a nice tan, well-cut hair, and just a bit of five-o-clock shadow.  

Her heart raced as adrenaline surged through her body. A strange, pulsing pressure manifested at the base of her spine and atop her head. When she stood to greet the guest, her shapely ass strained against the fabric of her skirt, she was sure this skirt fit the other day properly; how could it have shrunk? Did she wash it improperly?

"Hello, sir! Are you checking in?" Mina asked with a warm smile. She tried to remain professional, but it proved difficult when her panties wedged into the folds of her hot, steamy sex. I already have a man. I need to calm down, she lamented. 

"Yeah. I have a room for one reserved under Richard Stevens," he curtly replied, walking to the front as he pulled out his debit card and ID.

Mina nodded her head and made small talk as she checked him in. Wow, what a jaw-line, she thought as her nipples tingled and rubbed uncomfortably upon her inadequately sized bra. The pressure at the base of her spine boiled over as she felt something break through her skin and tear right through her skirt. Her cheeks flushed crimson, but she couldn't check to see what had happened.

"H-- Here are your cards!" Mina weakly laughed while sweat beaded and rolled down her face. There was a sudden pang in her nose as she handed them over. Something within her sinuses instantly changed as Richard's masculine, musky scent wafted through her nostrils. Her pupils dilated as her lips curled into a wide smile. "Please... Let me know if you need anything. I will be here all night," she purred, not noticing when two hard nubs sprouted atop her head.

Richard intently stared at Mina, unable to keep his eyes off her. An erection was already forming in his jeans. "What?" He blinked, looking down to see the cards in her hand. "Oh-- yeah. Thanks," he stammered, taking the cards before shuffling to the elevator.

She instinctively knew that this perfect male specimen held been aroused by her. All the while, her bra, and panties creaked and rubbed against her growing assets. She grew hornier by the second, taking deep breaths to calm herself. "I... I'm in complete control of myself. He's a stranger," she whispered in frustration. Despite her effort to reign in her thoughts, her mind still wandered. I wonder how big he is.  

A feeling of deep, unsatiated hunger and thirst erupted within her, screaming at her to feed. On what, though? She had eaten recently, and her stomach still felt full and happy. She licked her dry lips and took a swig of her water bottle, but it didn't help.

She remembered the ripping from a few minutes prior and immediately panicked and turned back. She shakily moved a hand down to feel around, and, much to her horror, she found a tail-like appendage that was now over two feet in length. It was taking on a darker color as well. "W-- What!?" She cried out, sliding her fingers over the new extremity. "Ahhhh!" A loud, lewd moan flowed from her lips as an orgasmic pulse shot through her pelvis and spread through her engorged vulva. The voice in her head screamed more loudly.

"Fuck. Feed. Self-indulge."

She shifted from foot to foot as an image of a naked Richard with a massive, throbbing cock manifested in her head. She walked away from the front desk without thinking and shakily sauntered to the elevator. Her ass and tits grew with every step, causing her bra and panties to fray at the seams.

"I need to see-- if he needs help... Maybe an extra blanket..." Her lips curled into a hazy smile as lust consumed her. As the elevator approached the third floor, she fondled her breasts through her top. "Mm-- ooh..." The top two buttons popped off from the pressure as her new, milky cleavage bulged out from the ill-fitted garment. This doesn't seem right-- no... This is unnatural. What the fuck is happening to me! She tried to assert control as the elevator doors opened. Her trembling finger hovered above the ground floor button, but she hesitated.

"Give in. Feed. Empower yourself."

Her breath rate picked up as her new horns grew and took on a dark red sheen. Her tail extended outward and took on a spaded, devil-like appearance. "What... Am I turning into?" She choked as tears fell from her face. She didn't want to be a slut; to be someone who would cheat on their man and suck off a stranger's cock.

It was hard to reason with herself when the idea of bedding with Richard turned her on more than ever. She pulled away from the button and walked down the hallway, moaning and mewing with every step. Her pussy rubbed against her panties, which now fit like a thong. When another button popped, her tits spilled out from her bra cups, now bare and exposed to the cool air.

She reached the correct room and eagerly knocked on the door. All the while, she licked her lips and fidged her fingers in anticipation. I can still turn back... I don't want this; I don't...

She tried her hardest to fight back, but that was all lost when Richard answered the door in his boxers and a tank top. 

He started to speak. "O-- oh, yeah? Can I help y--"

The next minute or two were a blur. She leaned in and passionately kissed Richard before he could finish his sentence, pushing her tongue into his mouth. It felt so damn right to do this. She could smell his precum, and it was utterly irresistible. "C-- Carry me to bed. Now." She purred. What would his seed taste like? She somehow knew his sperm was the only thing to curb her appetite.

When they got to bed, she kissed Richard and roughly ripped the clothes from his body like a ravenous animal. She noticed the stud of a male had an expression of something between absolute arousal and confusion. He listened and obeyed Mina's every whim.

"Take your clothes off. Present your cock to me and ask your mistress to tend to it," she said with a devilish grin. There was still a voice screaming at her and telling her this was wrong, but things were different now. She felt great power once the realization set in that this well-endowed male listened to her every command. The possibilities were endless.

After Richard obeyed and removed his boxers, his salty male scent immediately flooded Mina's senses. With a squeal of delight, she latched onto the eight-inch member and slid her tongue all over it, sucking and infusing her aphrodisiac-laced saliva into him.

"Make him climax. Make him obey. Take nourishment from him," her instincts commanded.

As her tail and horns finished growing, she continued to suck while her point of view changed. She felt a great deal of power inside of her. She understood on a primal level that every man from now on would cater to her every whim. They would all gladly offer their servitude and vital essence if she commanded. Sure, she had a boyfriend already, but she saw a new light at the end of the tunnel. If she gave into whatever force that was changing her, she could quickly obtain wealth and endless, blissful sex.

After another minute, Mina pulled away from Richard's throbbing penis and quickly stripped off her tight, sweat-drenched clothes. She sighed in relief when her bra and panties hit the floor and promptly descended upon Richard again.  

Without a second thought, she straddled his hips and took his turgid erection into her sensitive, succulent pussy. "Mmm-- yesss!" She moaned as her tail wildly flicked back and forth. She rode him hard as euphoric bursts of ecstasy exploded from her vagina and cascaded through her body like a mighty storm.

She hit her climax in unison with Richard. When his hot, sticky semen shot into her pussy, her body faintly glowed. She felt something akin to drinking a jug of ice-cold water after spending a day in the hot desert with no relief. Her new body happily absorbed Richard's seed, extracting the vital essence as a wellspring of power bubbled up within her. This was fucking incredible. Not only did she experience the most intense orgasm of her life, but the added sensation of feeding off his life energy multiplied the pleasure by many magnitudes.

She finally got off of Richard, still trembling and purring. Before she could decide on what to do next, her instincts kicked in.

'He has more to offer. Milk him again.'

Mina gleefully obeyed, sliding her fingers around the base of Richard's now half-flaccid cock as she gave a slight squeeze.

Richard's cock hardened instantly, standing as a pillar of pure masculinity. Men were supposed to have a refractory period, but succubi didn't need to worry about such trifling matters.

Why was I so upset about this a few minutes ago? She thought to herself as she intently stared at her prize.

"Let's do it like this," Mina purred as she got on her hands and knees, sticking her ample rear into the air. She swayed her hips back and forth while her tail happily swished.
