Chris says, "Stop—wait, Marnie. I don't have any condoms."
Marnie responds by kneeling. "That's fine. We have options." She slides her hand up the front of his groin, unzips his jeans, and frees his hardening dick from the confines of his underwear. "Mmm … already getting nice and big." She can hardly believe herself, on her knees in front of a man she felt was more of a mentor than a friend.
Whatever rationalizations have been going through Chris' head, he has obviously picked one and embraced crossing this Rubicon. "I want to feel those nice lips of yours wrapped around my cock," he says, "and then I want to fuck your mouth and fill your stomach with my cum."
Soon he gets his wish. First, Marnie strokes his shaft with her right hand, pumping it at an even pace as it gets harder and bigger. Her other hand massages and lightly squeezes his balls. When she is satisfied with his size, she takes him in her mouth—just the head, then she gradually swallows more, inch by inch, until the entire cock is inside her, and her nose is pressed against the base of Chris' stomach. "Mmmph," is all she can manage under the circumstances—but it seems to be an acknowledgement of pleasure and pride.
She bobs up and down the length of his cock. Part of her can't help but compare it to Steven's—Chris is a little bigger, for sure, but she isn't sure if he tastes much better. Marnie wonders if this is the secret to being a cockslut—that is, that all men's cocks are generally the same, so you might as well enjoy sucking off whoever, whenever.
Such philosophical ruminations are not really appropriate for the mood or the event, however, and Marnie feels her academic perspective dissolving as her demonic desires take over. She lets the cock slip from her mouth, then holds it by the base and licks along the underside. She spits on his head, polishes it with her tongue, then teases the inside of his slit. Chris grunts and takes a handful of her hair, pulling her more upright. Instinctively, she opens her mouth and tilts her head up slightly.
Chris rams the full length of his cock into her mouth with nothing resembling gentleness or patience. Marnie gags but manages not to spit him out. He uses his hands to hold her head and mouth in place, so she has little choice but to serve as a passive receptacle for his cock. Thinking of herself this way surprisingly makes her even wetter, and while he throat-fucks her, Marnie slips a hand down her skirt and starts fingering herself.
Yes, you do like being used like this, don't you? Uhazral's incorporeal form lurks within the dirtiest recesses of Marnie's mind, drinking up every bit of her pleasure from this sordid act. I think, however, that things could be improved.
Marnie can do nothing to protest or stop Uhazral as the demon sends forth its magic through the conduit of her body. The runes suffusing her skin glow orange, bathing both of them in brilliant light, but only for a second. Marnie feels a tingling in her throat—then she realizes it isn't her, but Chris' cock. It's growing.
In less than a minute the member has thickened and lengthened, now over seven and a half inches and likely two inches thick. Marnie can't help but gag as he continues to fuck her throat; she has never had a cock this long in her mouth and has no idea how to handle it.
"That's right, bitch," Chris says, becoming bolder as their illicit act continues. "I knew you were just an eager little slut all along. Take it."
His enlarged cock is almost fully inside her mouth when he begins to cum. As such, Marnie doesn't taste it at first. Instead she only experiences the strange sensation of feeling something sliding down her throat. After only a moment, he pulls out until just his head is past her lips, and more of his seed lands in her mouth. Uhazral has enhanced the man's sperm production as well; Chris cums for what seems like minutes, a furious stream of warm semen flooding Marnie's mouth. Finally, he pulls out entirely, shooting the last few waves of ejaculate onto her tongue and lips.
Marnie looks up at him appreciatively. She uses a finger to wipe the stray cum off from around her mouth, then seductively sucks the finger clean like a lollipop. "Mmm, that was so good—Chris." Leaning back on her hands, she adds, "So … I get that travel money now, right?"
Chris chuckles as he zips up his pants. His jeans were loose before but now display an unmistakable bulge as they attempt to contain his improved penis. "I guess you do. Just remember that this is our little secret, Marnie. If word of this gets out, you'll be down a thesis adviser."
"Well, I wouldn't want that," Marnie says. "Besides, I'm kind of looking forward to tasting that big cock again. Soon."
Marnie collects her clothing and takes a moment to compose herself before she leaves Chris' office. She is alone in the stairwell when Uhazral speaks again. You are getting much more comfortable with this, pet! I am pleased.
Fuck you, Marnie shoots back.
That is no way to speak to your master. I should punish you for such insolence—but I think you have done well enough to earn a reward instead.
Before Marnie can ask what the demon means, she gasps. She stumbles and presses her back against the wall as a wave of the purest pleasure washes over her. Unprompted, the orgasm seizes every muscle. Her vagina contracts around nothing, and her nipples engorge and press against the fabric of her bra, yearning for freedom and touch. Conflicting emotions race through Marnie's mind: shame, anger, hatred, desire, lust …
… acceptance.
It could be like this every time.
