Marnie just sits back and enjoys the show

For a moment—only a moment—Marnie almost closes the tiny gap between herself and Alexa on that couch and joins the two lovers. She can't tell how much of her arousal is … natural … and how much is the responsibility of the amulet around her neck. But her panties and tights are now soaked through, and she is making soft whimpers as she masturbates to the sight of Alexa getting her pussy stretched by Vic's massive cock.

The black-haired Hispanic girl is screaming with ecstasy. Vic is clearly enjoying himself as well. He grabs Alexa's ankles and pushes her legs up behind her head; fortunately, Marnie's friend is flexible enough for such a pose. Her labia look thicker and puffier from this angle, warm and wet and inviting to the big black cock that is thrusting in and out of her cunt.

"Have you been a bad girl lately? Have you?" Vic grunts as he increases the pace.

"Uhhhh, oh yeah. Yeah, I've been bad! I've been so bad!"

"Then you're going to have to get punished."

Alexa fixes her eyes on Vic's. "Oh? And what punishment did you have in mind?"

"Knocking you up and turning you into a black breeder might be a good start," he grins mischievously.

If Alexa's ardour is not strong enough to extend to impregnation, she doesn't get a chance to say so. Even as she next opens her mouth, Vic takes her discarded panties and shoves them in as a gag. Thus silenced, Alexa can only groan through the shiny black material as she endures his not-so-tender fucking. She lets go of one ankle to remove the soiled article from her mouth, but Vic pulls her legs back down and then flips her over onto her knees. He pushes her face against the back of the couch and pulls her legs apart to stabilize her, then he pulls her hands up behind her back and holds them clasped in one, strong hand while the other teases her pussy lips.

"Hhhhhhgh," Alexa says, unintelligible. Vic stops teasing her and guides his cock back into her. This time he takes it slow, driving himself deep into her pussy before pulling out and gently brushing the tip of his penis against her clit and labia. One of his hands keep hers behind her back, forcing her to press her face against the couch for support, and the other grabs her ponytail and uses it like a pair of reigns to pull her head upwards slightly. She is completely in his power.

Marnie is in rapture over this sight. She can't hold it back any longer; she comes, and it's an orgasm like nothing she's had before. The vision of Alexa's domination by a powerful black man has satisfied dreams she never knew she had—or did she have them before this amulet came into her possession? Marnie can't tell any more. All she knows is that she's loving the show.

Alexa is loving it too. It seems she is resigned to being Vic's broodmare, if that's what he wants from her. She has stopped resisting, and her eyes look blank and accepting as she thrusts her ass back up against his cock. Vic's breaths get closer and closer together as he comes closer to his release. At the last second, instead of fulfilling his promise to fill her up with his seed, he jerks his penis out of her and sprays his load over her wide ass instead.

A jet of semen spurts from his cum. Most of it lands on Alexa's perfect butt, the milky white globs of liquid and sperm immediately beginning to trickle downwards along the natural curves of her ass. Some of its goes as far as her hair and neck, and some lands on the couch around her. Alexa's going to have some clean up to do later.

"I changed my mind—this time," Vic says in a tone that brooks no argument. He releases Alexa from his grip, and the young woman yanks the panties from her mouth and turns around so that she is facing Marnie while still on her hands and knees on the couch.

"Thank you," she says. In reply, all Vic does is thrust his semi-flaccid member at him, and she happily guides into her mouth with one hand and starts to clean it.

Alexa has avoided becoming pregnant this time, but somehow Marnie understands that this change she has wrought is permanent. Her friend is going to be an eager black cumslut for good, and if Vic doesn't eventually knock her up during what is sure to be their frequent, frantic couplings, then another black man who comes along definitely will.

Marnie isn't sure what to make of this. After Alexa finishes cleaning off Vic's cock, she seems to remember that Marnie is there and right next to her. "Oh, still here? I thought you had left a while ago." She giggles, letting a little bit of extra semen dribble from the corner of her mouth down her chin. The perfect picture of a slut. "Sorry about that. I guess we got a bit carried away."

Vic echoes her laughter and strokes her face like a master rewarding his pet. "Just a little. Maybe next time your friend could join us."

Alexa shrugs as she stands up. "I don't know. Marnie's not exactly the adventurous type—and she has a boyfriend." Alexa says this like it's a dirty word, as if she would never be so dull as to settle for one guy.

Vic pulls on his articles of discarded clothing and heads for the door. "Well, I'll see you later, I guess."

"Wait." He turns, and a pair of panties hits him the face. He catches them in his hand and then kisses them before stuffing them in his pocket.

"See you," Alexa says, and she closes the door behind him.

Marnie stares at her. "See what I mean?"

"What?"

"You just let someone you hardly know fuck you right in front of me."

Alexa shrugs and goes over to the fridge, taking out a diet soda. "So?"

"So, don't you think that's a little bit out of the ordinary for you? Like, a-sex-demon-influencing-your-actions out of the ordinary?"

There is click followed by a pop as air rushes into the opened soda can. "No." Glug.

Marnie chews her lower lip. Then she sits up straighter as she realizes that, for the first time since she put on this stupid amulet, she feels … alone. Like there isn't a passenger in her head along for the ride. An idea comes to her, and she closes her eyes in concentration. This must look funny to Alexa, who says, "What are you doing now?" but Marnie only shushes her.

Sure enough, there's no response from Uhazral. She knows the demon isn't gone, but it is … quiescent. So Marnie goes out on a limb. She tries to replicate what she felt when she drew on the power of the amulet to change Alex and Vic. This time, however, she whispers a single word, over and over. "Remember." She opens her eyes.

A lone pattern of three runes pulses along her left forearm. And suddenly, the expression on Alexa's face changes. "Oh my God," she says. "Oh … oh my God. I didn't." Instinctively, she covers her chest, then realizing the futility of this motion after what Marnie must have seen, she lets her arms hang by her side again. Embarrassment turns to fury. "What the fuck, Marn? What the hell did you do to me?"

"I'm sorry. I—" Marnie wants to say she didn't have a choice, but that was the terrible part: she did. She had just chosen herself over her best friend. "I can't stop it." Which was true. Kind of.

"Am I … God. I’m like this permanently now, aren't I? Do you know I'm still thinking of his cock pounding into me, of letting him knock me up like some kind of baby factory? I'm picturing myself getting nice and round … fuck." She walks back over to the couch and sits down, knees modestly together but otherwise still immodestly unclothed. She looks at Marnie. "It's all true, isn't it? Everything you said. Why didn't I see it until just now?"

"When it … changes … people, I think they don't notice that anything is different. It's like all of reality gets altered so that whatever is happening is the new normal. So I just … made you remember."

"How? You said it's the demon doing this, not you. How can you use it's power."

"I'm not sure. Uhazral is silent right now. I think it's … feeding … on the psychic energy released when you and Vic had sex. It mentioned something when I first put on the amulet, something about harvesting that energy and using it to escape its prison. I think that's why it makes me do this. Every time I corrupt someone and they have sex, it gets stronger. But while it's feeding, it loosens its hold over me. I was able to borrow some of its power. And I don't think it's listening at the moment." Look at me, Marnie thinks, sounding like a demon expert.

"So what's the game plan?"

Marnie retrieves the letters from her bag. "These were with the amulet. I didn't have time to read all of them in detail, just skimmed a few. They might hold some answers, something about how to remove it at least. But I can't read them now, because unless I'm interested in sacrificing some more people on its altar, I can't guarantee that Uhazral won't be looking over my shoulder. So I need you to read them."

Alexa takes the proffered bundle and stares at them for a moment. "Me, Marnie? Are you sure? You know I hate reading the instructions on instant coffee, let alone … research." She wrinkles her nose. "Sure you don't want to ask someone more academic?"

Marnie takes her free hand. "There's no one else I trust more to help me."

"I'm touched." Alexa arches an eyebrow and gives a wry smile. She sets the letters down on the couch and stands. As she bends over to pick up her sweatpants and hoodie, she gives Marnie a nice view of her cum-stained ass. Marnie is surprised to find herself admiring it more than she would like to admit. Alexa pulls on her clothes and adds, "All right. I'll try. But you owe me, Marnie. And I don't mean for the research. I mean for that stunt you just pulled."

"Oh, come on, Lex. You know you loved it."

"Yeah, only because you made me love it!"

"Pfft. As if. You were a total slut already and you know it. I saw the way you were looking at Vic before I changed anything. Lending him DVDs? Come on, girl. You had already got your game on with him; I just … helped things along at the most."

"Whatever. Leave these with me, and I'll take care of it. In the mean time, what you are you going to do?"

Marnie sighs. "I don't know. I guess I have to go home."

"Are you sure that's such a good idea? What if this Uhaz-whatever wakes up and makes you, I don't know, turn Stephen gay or something like that?"

"I'm not sure. But I can't exactly go missing, can I? He'd be worried sick."
