"I'm a monster," you thought to yourself as you followed Elizabeth into town, though away from where you and your wife lived.
You knew what was happening and knew what would happen. You didn't like it, and wished desperately for it to be a dream, but it wasn't. You had been turned into a mermaid by a group of mermaids you had stumbled into while on a walk on the beach. And as a result, you learned what was food for them, and that was the "energy" of men. They lured men into the water, or used their shape-shifting powers to go on land, and drained human men of their energy. And you felt that hunger. You were growing more and more aroused as you followed Elizabeth. You could feel it. It was like hunger, and you were fairly certain that your self control was rapidly vanishing with it. You would end up with some horny man, that most women would prefer to avoid, and you would end up draining him. And as you walked, you were fairly certain that you wouldn't fight it. You were growing too horny... to hungry to fight it.
"I know you don't like this, Michelle, but it's the only way you can survive," Elizabeth said from where she was leading you.
You wondered if she was some sort of mind reader or simply knew that you weren't a big fan of how mermaids fed and was trying to console you. A lot of it didn't really work for you, but you went along with it. You had been feeling a sort of friendship with Elizabeth and you didn't want to upset her. Which you found to be strange, but you went with it. Of course some of that also had to do with the fact that if you didn't, you'd be returned to male form long enough to be fed on. Elizabeth didn't want to do it, but you did get the sense that she would reluctantly do it if she had to.
"I know..." you said slowly, "but... I'm... I'm so horny, I don't think I can fight it."
"I know, you..." Elizabeth began when she suddenly bumped into a large man that rounded a corner.
"Well... look what we have here," the man commented as he looked down at Elizabeth as she pulled herself up and as a smaller man came around the corner after him, "a couple of hotties out for a walk..."
"One's a hooker, judging by her top," the smaller man leered, "and both of them are smokin'!"
Elizabeth moved to help steady you, but she looked fairly calm.
"Goin' anywhere ladies?" the big man gave a grin.
"Anywhere there is a good time," Elizabeth smiled back, "would you like to?"
You stood by nervously glancing between Elizabeth and big man and his smaller partner. Your sexual hunger was so strong that you were certain that if Elizabeth weren't there, you would have jumped both of them in the street. You could feel your body desiring it. And you got the strange sense that they did to. Like it was how they were responding to yours and Elizabeth's pheromones.
"You bet we would!" the big man smirked again and moved Elizabeth back against the side of a building. The smaller man meanwhile came up to you. You soon felt his hands proceeding to feel up your chest and posterior right there on the street.
"Do you have a place a little more private then the street here?" Elizabeth asked the bigger man, "then we would be more then happy to give you your just deserts."
"Uh... sure, come with me," the big man nodded, and grabbed his smaller compatriot by the back of the neck.
Elizabeth then urged you forward as the big man walked toward the back door to a convenience store. He ushered smaller man in and held the door open for you, though you got the sensation that he wasn't doing so to be a gentleman. You ended up entering a dirty looking break room with the smaller man undoing his pants in front a worn couch. Your resistance was fading to your sexual hunger.
"So, private, eh?" the big man inquired.
"Good enough," Elizabeth shrugged, "You may feed now, Michelle."
You rushed forward and ended up driving the smaller man down into the couch. You were kissing and nibbling on his neck in a sexual manner before even making impact. Your mind was disgusted by this, but you were so hungry that you couldn't stop.
"Damn!" you heard the big man gasp, "yer friend's at like she's starving."
Elizabeth merely grabbed the man by the wrists and pinned him against the wall. She did nothing sexual to him and simply held him down like he was nothing.
"She is," Elizabeth said simply.
You could barely be bothered. You were horny beyond belief. You stopped kissing the smaller man long enough to take off the shirt you'd put on and exposed your D cup breasts to him. Your nipples were hard and ready, and you could soon feel him sucking on one of them. This elicited an aroused moan from you as you began to work on getting his pants down. You needed to feed and you were so horny that you weren't about to fight it.
His pants came off easily as he had already undone the buttons himself. After pulling his pants down, you exposed his fully erect member that stood up toward you. A part of your mind was disappointed at his size, but you were too hungry to care.
The smaller man continued to play with your breasts with one hand as the other began to pull down the pants you had put on.
"Thank you," you breathed as your vagina was exposed to him and you lowered your hands to his member to guide it into you.
"Ohhh..." the small man moaned, "thank... ohh... yeah."
In that moment you had lowered yourself onto him. It was strange to you, having sex as a female, feeling a penis inside you, but there was pleasure in it, and you weren't about to fight. You were too hungry to fight. As he began to thrust into you, you began to thrust back to maximize the pleasure from it. Your breasts bounced with each thrust and the small man did his best to massage them and play with your erect nipples. Your moans got loader and loader until you found yourself screaming.
"Oh yeah... yeah..." you moaned, "yeah... ohhh yeeeeeaaaah, yeeeeeaaaahhh... cum please... feeeeed meeeee."
"I'm tryin... oh man," the small man moaned beneath you, "oh man you're good... I'm gonna... I'm gonna... oh YES!"
And then he came. You could feel his member spurt inside you. He hadn't brought you to an orgasm yet, but he had triggered whatever way mermaids fed on humans. It felt like there was a second set of "lips" inside your vagina that gripped the man's penis and pulled him into you. He tried to pull out, but this second set of lips pulled against him would let him pull out. And at the same time, as he came, you began to feel stronger.
"Oh yeeeesssssssss!" you gave a contented moan.
"Oh God, Harvey.... Harvey she's a siren!" the bigger man gasped, "stop, Harvey, she's draining you!"
You looked down to the smaller man, Harvey. He seemed to have no knowledge over what was happening to him, but you could see it wasn't good for him. His skin was drying out and growing taut over his bones. Like he was wasting away. At the same time you felt yourself becoming stronger and some of the edge of your hunger vanishing. You were feeding on him. As you felt your lips finally release Harvey, you had left him looking like mummy of King Tut.
"Still hungry?" Elizabeth asked me.
"Still horny," you said weakly, and still sounding aroused.
"Please, I'm sorry!" the big man begged as you approached, nude, "please."
Part of you wanted to spare him, but you were still in the grips of your sexual hunger. You still needed to feed you let him know how much you were able to fight that hunger by pulling down his pants. He was much bigger then Harvey and he was also fully erect. Yours and Elizabeth's pheromones, no doubt.
"He's all yours, Michelle," Elizabeth spoke as you then lowered yourself onto the bigger man...
+++++++++++++++++++++
You and Elizabeth went out the same back door you had gone in through about ten minutes later. You had drained both of the two men, and left them as nothing more dried out and shriveled resemblances of a human being. Elizabeth was now wearing the big man's shirt over her bikini top, which did better to cover her breasts. You had also put your own clothes back on, but you shuddered heavily as you went out of the convenience store. You had killed two people by having sex with them. Something you'd never figured possible until now... but it was and you had done it. All to satisfy a siren's hunger. And as you and Elizabeth then began to walk toward where you and your wife lived, one thought still went through your mind now that the haze of your sexual hunger was gone.
"I'm a monster."
