Marlin silently stood before the doors of Cassandra's room

He audibly gulped. He may have agreed to this for Bela's sake, and normally any guy who had sex incoming would have yelled with joy but the circumstances around it where both unorthodox and downright terrifying.

Cassandra's reputation as a gleeful sadist was very much well known. So Marlin could only imagine the horrors that awaited him.

He knocked on the door. Shaking in his boots.

"Enter" he heard a voice on the other end say.

He pushed the through the door only to be met by the sight of an almost naked Cassandra. Wearing only a black bra and panties and sitting on the edge of her queen's sized bed. Her eyes now focused on him.

"Good that you're here manslave, come over here" she beckoned him as he silently moved towards her.

As soon as he reached her in her pale semi-naked form she commanded him "strip your clothes. All of it."

Marlin immediately complied, taking off his clothes without a second thought.

Cassandra observed him and his naked physique. She licked her lips as she laid eyes on his member and his muscled chest. My, my dear sister you do know how to pick them she thought.

Immediately wasting no time she grabbed him and threw him on her bed and dropped on top of him. Sinking her teeth into the skin of his shoulder. The manservant screamed out in agony. The pain never got easier, you could never really got used to it.

Cassandra gulped and licked the life fluid from his shoulder in much the same as she always did, as painful and dragging it out as much as possible. Marlin could only take it, as per usual he was a subject to their whims and desires.

She dragged her teeth out of his shoulder, licking her lips as she did.

"You taste so good manslave, now let's see what you're made off"

In an instant her lips where forced on his unexpected ones. As she tried to force her tongue down his throat she ran her nails down his chest, leaving scratched to make him bleed. Marlin yelped as his lips where assaulted.

"Are you going to make me do all the work manslave?" Cassandra asked sarcastically. Marlin tried to respond but couldn't get a word out on account of the stringing pain in his shoulder and chest.

His feeling was interrupted by Cassandra digging her nails into the cut on his shoulder. Causing him to scream out.

"I WAS ASKING YOU SOMETHING MANSLAVE!" she yelled as she dug her nails in deeper.

"Aaaah! I….I" he tried to get out but the pain was too intense to concentrace.

"Yes?" Cassandra wondered sarcastically.

"I….I…I aim to please you miss Cassandra….to do as you wish" he said trying not to scream as she finally removed her nails from his now bleeding wound.

"Aww how sweet of you," Cassandra said looking sweetly, her chin full of the smear of his blood "so sweet of you to think of me manslave. But if you aim to please me, you better put in some effort."

In the blink of an eye she had torn her bra of her and thrown it across the room. Marlin gasped as her breasts bounced, clearly bigger than her sisters, her nipples hardening from the sudden chill. She grabbed his hands forcefully and placed them on her mounds.

"Use those hands manslave, and use them well or maybe I come to the conclusion you don't need them" she told him menacingly before she went back down to kiss him again.

Marlin was overtaken by multiple feelings at the same moment. Pain and pleasure as Cassandra forced her tongue into his mouth and he had no choice but to oblige, colliding his with hers. She was definitely rougher than her sister, much rougher.

Her breasts felt heavy in his hands, pushed against his palms as she dominated his mouth. Then Marlin tried being bold.

He squeezed hard.

He heard her moan in his mouth and she looked at him, a fire in her eyes. A fire of passion.

"Like that manslave, you're a quick learner" she told him, a seductive yet vicious smile on her face as she returned to kissing him. He once again gave a hard squeeze. She was moaning above him, pleasure building up.

Her lips removed themselves from him as she gasped at the feeling of another squeeze.

Her fingers lingered on the top of chest, looming close to the freshly made cuts she had made earlier. She was tempted to leave another scratch until he squeezed her breasts again, causing a loud moan.

"Hmmm….such a good boy you are," she told him sweetly, letting her hand go around his hardened erection behind her "and a nice size too. No wonder sister wanted to keep you to herself."

She laughed as she leaned forward, her eyes staring into his.

"And now….you're mine!"

Immediately and with a quickness he didn't know was possible, Marlin found himself again at her mercy as she moved backwards and instantly took his erection into her warm wet mouth.

Marlin's head fell back with a moan as pleasure shot through his body like a sugar rush. His cock pulsated as it was devoured by Cassandra's hungry lips. She was rough and wild as opposed to Bela's more methodical and calm way of pleasuring him. Cassandra was hungry and she wanted more.

The manservant's moans filled the room and it was no doubt a great source of pleasure to the middle Dimitrescu daughter. She loved having a man at her feet, or well at her lips in this instance.

"Miss….I'm going too" but before he could finish Cassandra's hand was around her face "oh no you're not. You're not coming until I say so GOT IT!" she said.

Her capability to switch from sweet to outright anger was still surprising to Marlin to this day.

"Yes mistress" he suddenly said.

"Hmmm….Mistress, I liked the sound of that. You call me for that from now on understood" she demanded. Marlin nodded in response.

"Such a good boy" she said sweetly as she returned to sucking his cock.

Marlin tried to hold back but she was making it very difficult. Maybe this was her idea of torturing him. Making him hold back lest he face the consequences. Which would undoubtedly be way more terrifying.

She was good, she sucked and licked at the same time, squeezing his member tight and for all that it was worth. But eventually every man no matter how powerful, succumbs to the temptations of a powerful woman.

He couldn't even warn her as he came, shooting a load straight down her throat as she reeled back in surprise, the leftover seed squirting onto her chin and part of her hair.

The afterglow to Marlin was incredible only to be broken as he laid eyes on Cassandra, his semen dripping down her chin and in part of her hair.

Her reaction was instant. Grabbing him by the throat and squeezing tight.

"DIDN'T I TELL YOU NOT TO CUM UNTIL I TELL YOU TO YOU GOOD FOR NOTHING MANSLAVE!"

Her following act was to bite down deeply into his already bleeding shoulder and scraping her nails and digging deep into his chest. He cried it out in agony. She wanted him to suffer.

"I'm sorry mistress" he cried out in vain.

If she heard it then it didn't bother her because her teeth went even deeper into his skin and so did her nails. Tears forming in his eyes as he continued begging her to stop the pain but nevertheless she persisted.

After what felt like hours she finally released his shoulder from her fangs and looked at his crying face.

Her face immediately softened.

"Awww is the poor manslave crying" she proceeded to lick up the tears on his cheeks. "Did you learn your lesson little boy?" she asked softly holding his face in both hands.

"Yes…Mistress" Marlin snickered.

She smiled at him, not her usual sadistic smile but an almost genuine smile.

"Good boy," she kissed his cheek "now since you apologized so sweetly and you took your punishment like a good slave. How about you can have something too. Is there anything you would like to try manslave? This is the only offer you'll ever get from me."

Had he entered the Twilight Zone? Or the Bizarro universe? The woman who just mere seconds ago was making him bleed for disobedience was now offering him a chance to do anything he wanted. Had he underestimated Cassandra? Was this another of her sick twisted genie in a bottle type situation where she would turn it around him.

"Well?" she asked impatiently.

"I…." Marlin had never been put into this position before, a position of control, or at least to an extent. He didn't know exactly what he wanted, it's always been about what they wanted. But now the tables were turned, even just momentarily.

"I would like to spank you mistress" he ultimately said.

Cassandra raised her eyebrows at surprise "my, my such a naughty slave you turn out to be" she said patting the side of his face. "But I'm a woman of my word so" with that Cassandra turned around and removed her last article of clothing as she laid flat on her belly, her round pale ass standing out.

Marlin gulped. This should be insane, he shouldn't be doing this. But she was just laying there, giving him permission to do as he pleased.

"What are you waiting for slave, a written invit….. AAAH" Cassandra yelled out as his bare hand made content with her right butt cheek.

"Fuck….." Cassandra muttered out as Marlin reeled back in fair "I'm sorry mistress I didn't mean to…"

"SO GOOD!" he heard her say midsentence as she turned to him "again and harder this time!"

Upon hearing that he couldn't stop himself.

Another smacking noise filled the room as he once again spanked her, and she yelped it out. Begging for him to do it again. The powerful and imposing Cassandra was now begging for her manservant to spank her ass bare.

Marlin couldn't believe he had so much power now. It felt good. It felt right.

As he slapped her butt a fifth time she cried out "Fuck!" and her moans echoed through the room. She slowly turned to him and he half expected her to lunge at him out of restrained anger. But as he saw her face, he only saw burning passion.

Her butt was marked with his red handprint and she crawled to him, licking her lips.

She grabbed his face in both her hands and said in no uncertain terms a lot "Fuck me!"

Marlin's fire was alight and he grabbed her face to pull her into a kiss as he made her fall backwards on the bed, assaulting her mouth with his. Cassandra was moaning in his mouth, her hands holding onto the back of his head.

He was rock hard in an instant and aligned himself with her, pushing in and causing Cassandra to yelp.

"Fuck me hard manslave! Fuck me like a man" she demanded as he pushed himself deep inside of her. Cassandra's long black locks where now sweat covered around her face and she dug her nails into his back.

Marlin pushed and thrust forward as far as he could before pulling out. She was tight and it felt absolutely incredible! Cassandra moaned around him as he pushed and pulled, his lips almost never leaving hers as this intimate interaction continued.

"Fuck!" Cassandra yelped "harder! Harder!" she half begged and half demanded as he continued to try and please the woman who had been torturing him for years. Oh how the tables can turn so suddenly.

Minutes of pleasure filled the room until Cassandra yelped out the loudest moan as her orgasm overtook her, following that up with Marlin filling her once again, making her eyes go white with pleasure just like Bela's as she indulged in the incredible feeling.

Marlin collapsed on her as the afterglow hit them both. A blissful peace washed over them.

Oh I'm definitely keeping this one, Cassandra thought to herself.
