Mark knew, on some level, that you weren’t normal.
But that never stopped him from loving you.
You were his, and that was all that mattered.
And well… it wasn’t like he was thinking much at all when you were looking at him with those wide, dazed eyes, lips slightly parted in confusion as he pressed soft, open-mouthed kisses down your stomach.
Not when he was between your legs, pressing your plush thighs apart, eyes locked on the glistening heat between them. You were already wet, slick coating your folds, and fuck—his mouth watered just looking at you.
Mark licked his lips. "You're so pretty, baby."
You blinked at him, tilting your head. "Mate…?"
His heart ached at how confused you looked. God, you really didn’t know anything, did you? His perfect, innocent pretty girl. All you understood was that he was yours and you were his, but everything else—well, he had to teach you.
That made his cock throb.
"I'm gonna make you feel good," he murmured, pressing a kiss to your inner thigh.
Your brows furrowed. "But…?" You fidgeted, clearly unsure. "That… not for… making baby?"
Mark groaned. His hands squeezed your soft thighs, thumbs rubbing circles into your skin. You were so fucking cute. So perfect.
"I just wanna taste you," he said, voice hoarse. "Trust me, baby. You'll like it."
You made a small noise, still confused but trusting, and that was all he needed.
Mark licked a slow, teasing stripe over your folds, groaning at the taste of you. He felt you jolt, thighs twitching, a startled gasp leaving your lips.
"Mark!" Your fingers tangled in his hair, confused and overwhelmed.
Fuck. He needed to hear that again.
He latched onto your clit, sucking gently, and you whined, your whole body trembling. You were so sensitive. Every tiny movement of his tongue made you react, hips jerking, hands gripping him like he was your only anchor.
"You like that?" he murmured, lips brushing against you.
Your breath hitched. "Feel… strange…"
He chuckled, kissing your inner thigh. "Good strange?"
You hesitated, chest rising and falling rapidly. Then, shyly, you nodded.
That was all he needed.
Mark ate you out like a man starved. He licked, sucked, and kissed every inch of your dripping cunt, groaning every time you gasped or moaned his name. He wanted you like this forever—helpless, needy, completely at his mercy.
When he slid a finger inside you, your walls clenched so tight he nearly lost his mind.
"Fuck," he rasped. "You're so tight, baby. Gonna let me fuck you, yeah?"
You whimpered, clutching at his shoulders. "M-Mark…!"
He kissed you, swallowing your moans as he lined himself up. Your body clung to him, soft and warm, and when he finally pushed in—fuck—he nearly lost it.
You gasped, wrapping your legs around him, nails digging into his back. He could feel your walls fluttering around him, trying to pull him deeper, like your body knew he belonged there.
"Mine," he groaned, rocking his hips. "You're mine. Say it."
You whimpered, overwhelmed. "Y-Yours…! Mate…!"
"Good girl."
He started moving, slow at first, then rougher, deeper. He couldn’t help it. You felt too good. You were perfect—made for him, just like he’d always known.
And when he felt you tightening around him, trembling, gasping his name—he lost it.
He filled you up, holding you close, breathless and shaking.
You shivered, eyes blown wide as you felt it. Felt him spill inside you.
You liked that.
You really, really liked that.
Mark had no idea you were pregnant. Because you? You looked the same. No weird cravings. No morning sickness. Nothing. The only thing that changed was that you got even clingier. Mark would be sitting on the couch, and you’d crawl onto his lap. He’d be eating, and you’d steal his food. He’d be talking, and you’d lick his face to get his attention. "Babe—" "Warm." "Yeah, I know, but—Jesus Christ, stop biting my neck!" You were all over him. Touching him. Holding him. Curling up against him like he was your personal teddy bear. Mark, the horny dumbass that he was, did not question it. He just assumed you really, really liked sex.
Mark was completely, utterly, hopelessly in love with you. Which was really bad, because you weren’t human. You weren’t even close to human. And now? You were curled up against him, his. And Mark was happy. At least, until Nolan showed up. Nolan had just returned, stepping through the door, and then he saw you.
Mark should have known something was wrong the moment Nolan froze.
His father had seen a lot. Done a lot. But when he saw you his expression twisted.
"...Mark." His voice was tight. "Who is this?" Mark blinked. "Oh—uh, this is my girlfriend."
Nolan didn’t react. He just stared. At first, he didn’t know why, but something felt wrong. Something felt off. You were sitting on the floor in all fours, chewing on a fucking slipper. Like a feral animal. Mark sighed. "Baby, what did I say about chewing things?" You blinked up at him, slipper hanging from your mouth. "…No?" He groaned, rubbing his temples. Meanwhile, Nolan was staring at you. That was not a normal person.
Because something about you—about the way you moved, the way your eyes shined just a little too brightly—felt off. Unnatural. Dangerous. Mark didn’t notice. He just kept talking, completely oblivious. "She’s kinda weird, but she’s sweet, y’know? She doesn’t really get human stuff, but she’s learning. Right, babe?" You looked up, smiling, before biting his finger. Mark sighed. "Yeah, she does that." He didn’t say anything at first. Just watched. Observed. And then, later that night, he did some digging. And when he finally found what you were? He froze. Because you weren’t just some alien girl. You were a Qu. A Queen. The stories—the horrors—he read about your species made his blood run cold. Qu were monsters. Galactic horrors. They didn't care about power, they didn't care about respect or fear. They did not form relationships. They did not love. They consumed.
A species so terrifying that the universe pretended they were extinct. A species that rewrote DNA like a child scribbling over a book. A species where the queen ate its own males.
The next time he saw you, Nolan barely concealed his unease. Mark had left the room for a moment, and he turned to you, his voice low. "You can stop pretending now." You blinked. And then—your entire posture shifted. You sat up straight, spine elegant, hands resting in your lap. Your eyes—normally soft and stupid—were cold. Expressionless. Your lips curled into something that wasn’t a smile. "Oh?" You hummed. "Figured it out, did you?" Nolan didn’t react. "I know what you are." You chuckled. Soft. Delicate. But it did not reach your eyes. "And what will you do, Nolan Grayson?" You tilted your head. "Kill me?" He said nothing. You leaned in, voice gentle. "Try it." And then—your voice turned sweet. "I will rip the flesh from your bones. I will wear you as a coat and sit on a throne made of your ribs. I will fill your lungs with your own bile and make a feast of your insides. You will watch, helpless, as I unravel every nerve in your body, plucking each one like the strings of a violin." You smiled. Soft. Sweet. "And when I’m done? I will hand your skull to your son as a gift." Nolan stiffened. A chill ran down his spine. Because he knew—he knew—you weren’t lying. You meant every word. And when Mark returned, grinning at you like a dumbass, you immediately returned to your adorable, brainless self. "Mark!" You climbed onto his back, nuzzling into his neck. "Miss." He laughed, holding you. "I was gone for two minutes." You pouted. "Long. No like." Nolan could only watch. And the worst part? Mark had no idea what you really were.
He didn’t notice you were pregnant. You never told him. You didn’t get sick. You didn’t act any different. You still followed him around, still sat in his lap, still licked his face when you were happy. But then, one day, as you were lying on the couch, Mark paused. "...Are you getting fat?" Your head snapped toward him, eyes wide. Mark immediately realized his mistake. "WAIT—WAIT—WAIT—DON’T GET MAD—" But you just blinked. Looked down at yourself. Then poked at your stomach with curiosity. "...Fat?" Mark swallowed. Oh, shit. You were never concerned about your body before. Hell, you barely even cared about clothes. But now? Now, you were poking your stomach like it was an alien parasite. Mark gulped. "Uh… yeah, just a little?" You tilted your head. Thought for a long moment. Then shrugged. "Good." Mark blinked. "Wait… that’s it?" You hummed. "No care. Body… change." "...What does that mean?" You just smiled. Mark didn't like that smile.
