The Stark Effect

An Uncharacteristic Wave of Exhaustion.

Hi everyone! 💕 Welcome to The Stark Effect! I hope you enjoy Nia's story as much as I enjoyed creating her. This is my own take on the MCU, so there will be some changes to canon and plenty of original elements.

Please keep in mind that this is fiction, and some characters, relationships, and events have been changed for the story. I hope you enjoy reading! 💜

Olivia Harris was twenty-one years old, working toward her associate degree in sound engineering at Santa Monica College while commuting from a small, sun-bleached apartment near the Malibu border. She stood five feet seven inches tall, with rich, warm mahogany skin and expressive, almond-shaped dark brown eyes framed by long lashes. Her natural hair was styled in a crown of springy, defined afro curls that fell near her shoulders, catching the California sun with subtle reddish undertones. She possessed an athletic build, refined from years of track in high school, and carried herself with an easy, unbothered confidence. For her unauthorized trip up to Point Dume in late 2000, she wore a thrifted, emerald-green silk slip dress that contrasted sharply with her complexion, paired with understated gold hoop earrings and minimalist black heels.

Olivia was an orphan who had been fostered by an abusive family starting at age eleven. She never knew her birth parents, only knowing that her first name was Olivia and her last name was Harris. Ever since age eleven, she had been a huge fan of Tony Stark, fascinated by his genius and life. Her personality was awkward and klutzy, but she was deeply intelligent and stubborn, having always wanted a true family of her own.

Getting past security at the Point Dume mansion wasn't about high-tech manipulation; it was about timing. Olivia knew the catering company working the bash at 10880 Point Dume hired temp staff through a local agency. She simply arrived during the chaotic evening vendor drop-off wearing a black blazer over her dress, carried a clipboard, and walked right past the valet checkpoint while the guards were distracted by an influx of luxury sports cars. Once inside, she slipped off the blazer, left it in a quiet hallway, and smoothly blended into the sprawling, music-filled cliffside estate.

Tony was holding court by the bar near the pool with a glass of Scotch in hand. When he spotted Olivia near the sound setup-critiquing the acoustics of his high-end speakers-he gravitated toward her.

"You're not looking at me," Tony noted, stepping into her space with his signature wry smirk. "Usually, people look at me. It's in the unwritten rulebook."

"I'm looking at your frequency balance," Olivia replied, glancing at him with a faint smile. "Your high end is clipping on the patio speakers."

Intrigued by her sharp mind, lack of awe, and quiet charm, Tony spent the rest of the evening talking exclusively with her. The chemistry was fast and effortless. What began as clever banter over acoustics eventually moved away from the loud crowd and into his private quarters.

The moment the heavy door clicked shut behind them, Tony's hands were already on her. He backed her against the wall of his sprawling master suite, the ocean crashing faintly beyond the floor-to-ceiling windows. His mouth claimed hers in a deep, hungry kiss that tasted of Scotch and pure intent. Olivia's fingers curled into the lapels of his open collar shirt as he pressed the hard length of his body against hers. He broke the kiss just long enough to drag the thin straps of her emerald silk slip dress down her arms. The fabric whispered over her skin and pooled at her feet, leaving her in nothing but a simple black thong and the gold hoops at her ears. Tony's eyes darkened as he took her in-high, full breasts, the tight plane of her stomach, the strong thighs that spoke of years on the track.

"Fuck," he murmured, voice rough. "You're even better than the smart mouth suggested."

He cupped one breast, thumb sweeping over the dark nipple until it tightened, then bent and sucked it into his mouth. Olivia's head fell back against the wall with a soft gasp. His other hand slid down, palm gliding over the curve of her hip before slipping beneath the waistband of her thong. Two fingers found her already slick, parting her folds and stroking over her clit with deliberate pressure. She rocked against his hand, awkwardness melting under the heat of it. Tony worked her steadily, fingers sliding deeper, curling just right while his mouth moved to the other breast. When her thighs began to tremble he pulled back, eyes locked on hers.

"Bed. Now."

He guided her across the room, shedding his own clothes as they went. Shirt, trousers, boxers-all discarded in a careless trail. By the time the backs of her knees hit the edge of the massive bed, Tony was naked, cock thick and already leaking at the tip. He pushed her gently onto the mattress, hooked his fingers in the sides of her thong, and dragged it down her legs. He settled between her thighs, shoulders spreading them wide, and dragged his tongue through her wetness in one long, slow lick. Olivia's hips jerked. He did it again, then focused on her clit, sucking and circling with the kind of focused intensity he usually reserved for engineering problems. Two fingers slid back inside her, pumping in time with his mouth until she came hard, thighs clamping around his head, a broken moan tearing from her throat.

Tony rose over her, wiping his mouth with the back of his hand, that signature smirk back in place. He lined himself up and pushed in with one smooth, relentless thrust, burying himself to the hilt. Olivia's back arched; the stretch burned in the best way. He gave her only a second to adjust before he started moving-long, deep strokes that filled her completely. The rhythm built quickly. The slap of skin on skin filled the room, mixed with her soft, surprised sounds and his low, filthy encouragement. "That's it-take it. God, you're tight." He hooked one of her legs higher, changing the angle so every thrust dragged over the spot that made her see stars. Olivia came again with a sharp cry, inner walls fluttering around him. Tony followed moments later, burying himself deep and spilling inside her with a guttural groan, hips stuttering as he filled her.

They stayed locked together for a long minute, breathing hard. Then he rolled them, keeping her draped over his chest, one hand lazily stroking the damp curls at the back of her neck.

By morning, Tony had already been whisked away by Pepper Potts for an unexpected press briefing in Los Angeles, leaving Olivia to slip back out into her regular life. Nine weeks later, the persistent morning nausea and an uncharacteristic wave of exhaustion prompted Olivia to buy a test from a local pharmacy. Sitting on the edge of her cramped bathroom counter in Malibu, she stared down at the two dark pink lines. She was twenty-one, finishing her finals, and carrying the child of Tony Stark.

This story is ultimately just for fun, but I'm still putting a lot of research into it to keep things as accurate to the MCU as possible. I plan on covering all three Iron Man movies, the Avengers movies, the Home trilogy, and eventually Brand New Day. Of course, I won't be including every single scene from each movie because that would make the story unnecessarily long. I'll focus on the important moments while incorporating Olivia and Nia into the story as naturally as possible.

For the first few chapters, we'll be focusing on Olivia's pregnancy, with Chapter 5 being Nia's first proper introduction.

I hope you guys enjoy the story! Please leave comments and votes if you're enjoying it. They really mean a lot! 💜
