Forbidden Circuits

**Chapter 1: The Unexpected Invitation**

Vander adjusted his tie in the mirror, the mundane rhythm of family life humming around him. Aline, his wife of twelve years, was corralling their three kids out the door for school, her voice a sharp whip of efficiency. He loved her, truly, but there was a fire missing—something raw and untamed that had flickered out somewhere between diaper changes and mortgage payments. His mind, as it often did, wandered to Terezinha.

Terezinha, Aline’s grandmother, was a force of nature. At seventy, she stood tall, her presence commanding with thighs that could crush a man’s resolve and an ass so huge it seemed to defy gravity. Her full breasts strained against every blouse she wore, and her skin, though weathered by time, told stories of a life fiercely lived. Vander had caught himself staring more times than he could count, his pulse quickening at the thought of her raw, unapologetic vitality.

His phone buzzed on the counter, snapping him out of his reverie. A text from Terezinha. *Vander, my computer’s acting up again. Can you swing by my apartment this afternoon? Augusto’s out golfing, and I’m hopeless with this tech nonsense.*

A grin tugged at his lips. An excuse to be alone with her. “I’ll be there,” he typed back, his fingers trembling just slightly.

The elevator ride to Terezinha’s apartment felt like an eternity, each floor ticking by with a thud in his chest. When she opened the door, she was a vision—wearing a loose floral dress that clung to her curves in all the right places, her silver hair pulled back to reveal the sharp lines of her jaw. Her eyes, still piercing, raked over him with an intensity that made his breath hitch.

“Vander, you’re a lifesaver,” she purred, her voice a low, smoky drawl that sent a shiver down his spine. “I swear, this damn machine hates me more than Augusto’s cooking.”

He chuckled, stepping inside, the scent of her lavender perfume wrapping around him like a forbidden promise. “Let’s see what’s wrong with the old beast. Probably just needs a firm hand.”

Her lips curled into a wicked smirk as she led him to the small desk in her living room. “Oh, I know all about firm hands, darling. You think these thighs got this way from sitting pretty?”

Vander swallowed hard, his throat dry as he bent over the computer, hyper-aware of her standing just behind him. Her presence was a heat at his back, and he could feel her gaze burning into him. “Just a few clicks here… looks like a virus. I’ll clean it up,” he muttered, trying to focus.

Terezinha leaned in closer, her breath hot against his ear. “You’re good with your fingers, aren’t you? Always fixing things. Makes a woman wonder what else you’re good at.”

His hands froze on the keyboard, a jolt of electricity shooting through him. He turned his head slightly, meeting her gaze. Her eyes were molten, daring him to cross a line he’d only fantasized about. “Terezinha, you’re playing a dangerous game,” he warned, his voice rough.

She laughed, a deep, throaty sound that made his blood race. “Boy, I’ve been playing dangerous games since before you were born. Question is, are you man enough to keep up?”

Before he could think, she pressed herself against him, her massive curves molding to his back. His cock stirred instantly, hardening against the constraint of his jeans. He stood, turning to face her, their bodies inches apart. “You’re my wife’s grandmother,” he growled, but there was no conviction in it.

“And you’re a man who’s been eye-fucking me for years,” she shot back, her hands sliding to his chest, fingers digging in just enough to make him groan. “Don’t pretend you haven’t thought about this—about me. I see it in your eyes every damn time you’re near.”

His resolve crumbled like ash. He grabbed her hips, pulling her closer, feeling the heat of her through that thin dress. “You’re trouble, Terezinha. Pure, fucking trouble.”

“Damn right I am,” she hissed, her lips crashing into his with a hunger that stole his breath. Her kiss was fierce, demanding, her tongue claiming his mouth as if she owned it. His hands roamed, gripping her huge ass, marveling at the sheer power of her body as she ground against him, her pussy pressing against his thigh through the fabric.

She pulled back, panting, her eyes wild. “I’m not some delicate flower, Vander. I want it hard, and I want it now. You gonna give me what I need, or are you just all talk?”

His response was a low growl as he pushed her back toward the couch, his body thrumming with raw, desperate need. Her dress rode up, revealing those thick, powerful thighs, and he knew there was no turning back. She was wet, he could sense it, dripping with the same hunger that had him sweating, his cock straining painfully. This was about to explode, and neither of them cared about the consequences.
