Back in their luxurious penthouse, the weight of another failed night hung heavy in the air like a storm cloud. Mimi and Tae sat on the edge of their massive bed, the silk sheets still rumpled from their earlier attempt at intimacy. Mimi, her pretty face flushed with a mix of frustration and lingering arousal, curled up against Tae’s broad chest. She was wearing a simple tank top and shorts that hugged her slim hips, her small breasts pressing softly against the fabric, nipples still perky from the foreplay that had gone nowhere. Tae, shirtless in his gray sweatpants, wrapped his tattooed arm around her, his handsome features etched with guilt. His dark hair was tousled, and his full lips were set in a grim line as he stared at the city lights twinkling outside.

“Baby,” Mimi whispered, her voice soft and trembling, tracing patterns on his toned abs with her fingertip. “We can’t keep doing this. The doctors we’ve seen… they’re good, but nothing’s working. I want our baby so bad. I want to feel you inside me, filling me up, making me swell with your child.” Her doe eyes filled with tears, making her look even more innocent and vulnerable. Tae’s heart twisted; he loved her fiercely, but his body betrayed him every time. His massive cock, hidden under those sweatpants, was a cruel joke—a thick, veiny monster that could destroy a woman if it ever fully hardened, but with Mimi, it barely stirred.

“I know, princess,” Tae murmured, kissing the top of her head. “We’ve tried everything—pills, injections, even that couples therapy bullshit. I’m just… broken.” He hated admitting it, his voice rough with shame. As the head of a billion-dollar empire, he commanded respect everywhere else, but here, in their bed, he felt like a failure.

Mimi sat up, her long hair falling over her shoulders, and cupped his sharp jaw in her hands. “You’re not broken, Tae. You’re perfect. My perfect husband.” She bit her lip, hesitating, then plunged in. “What if… what if we go see my mom? She’s the best fertility specialist in the country. Her success rate is insane. She could help us.”

Tae’s eyes widened, his handsome face paling. “Your mom? Koo? No fucking way, Mimi. That’s… that’s embarrassing as hell. She’s family. How am I supposed to talk about my dick not working with my mother-in-law? Christ, she’d think I’m not man enough for you.” He shook his head, his broad shoulders tensing. The idea made his stomach churn—exposing his vulnerability to the woman who’d raised his wife? Humiliating.

But Mimi’s lower lip trembled, her eyes welling up with fat tears that spilled down her cheeks. She pouted, that sweet, teary expression she knew melted him every time. “Please, Tae? For me? For our family? I hate seeing you like this, so frustrated. Mom won’t judge—she’s a professional. And she’s helped so many couples. Imagine it: me pregnant, our baby growing inside me because of her help.” She leaned in, pressing her soft body against his, her small hands roaming his chest, pleading with every touch. “Begging you, hubby. Pretty please?”

Tae groaned, his resolve crumbling under her teary gaze. How could he say no to that face? “Fuck… alright, fine. We’ll go see her. But if it’s too weird, we’re out.” Mimi squealed, throwing her arms around him, peppering his face with kisses. “Thank you, baby! You’re the best!” Deep down, Tae dreaded it, but for her, he’d endure anything.

The next morning, they arrived at Koo’s upscale clinic, the glass doors sliding open to reveal a waiting room that screamed luxury—plush chairs, fresh flowers, and soft classical music. Mimi squeezed Tae’s hand as they checked in, her pretty face bright with hope. Tae, dressed in a crisp button-down and slacks that hugged his muscular thighs, tried to look composed, but his mind raced.

When the nurse called them back, Koo was waiting in her office, perched on the edge of her desk like a queen on her throne. She was stunned for a split second—her daughter and that tall, handsome son-in-law? Here? But she masked it with a warm smile, her full red lips curving invitingly. Koo looked like pure sex today: a skin-tight red dress that plunged deep between her massive tits, the fabric straining over her heavy, jiggling boobs, nipples faintly visible through the thin material; the hem barely skimmed her thick thighs, her juicy ass practically spilling out when she moved; and black stilettos that made her legs look endless. No bra, of course—her tits bounced freely—and under that dress, her fat pink pussy was bare, already tingling at the sight of company.

“Mimi! Sweetheart!” Koo exclaimed, opening her arms. Mimi rushed forward, hugging her mom tightly, their bodies pressing together—Mimi’s petite frame against Koo’s curvy voluptuousness. “Mom, thank you for seeing us on short notice,” Mimi said, pulling back with a smile. Tae hung back, but his eyes widened, stunned by his mother-in-law’s slutty outfit. Holy shit, he thought—those tits were enormous, threatening to burst free, and that dress left nothing to the imagination. He’d always known Koo was beautiful, but up close? She was a walking fantasy, her beauty eclipsing Mimi’s in a raw, sexual way. His cock twitched involuntarily, a rare spark, but he shoved the thought down, ashamed.

Koo ushered them to sit on the plush couch across from her desk. “Of course, darling. Now, what’s going on? You two look… troubled.” Mimi glanced at Tae, who nodded stiffly, and she spilled it all: their marriage, the love, the wealth, but the heartbreaking struggle for a baby. “We’ve been trying for over a year, Mom. All the tests say I’m fine, but Tae… he has erectile dysfunction. Nothing works. We thought you could help.”

Koo’s eyes softened with genuine sympathy for her daughter—poor Mimi, so young and sweet, desperate for motherhood. She hadn’t known they were even trying; Mimi kept things private. But as the words sank in, Koo’s fat pussy clenched with excitement. Her special therapy on her own son-in-law? That massive, handsome man with a cock problem? Her mind raced with filthy possibilities—teasing him, touching him, making that dick hers to command. Her nipples hardened under her dress, and she crossed her legs, feeling her slick folds rub together. “I’m so sorry, loves. We’ll fix this. Tae, if you’re comfortable, I’d like to do a quick exam. Just to assess.”

Tae’s face burned red, his sharp jaw clenching. “Here? Now?” He glanced at Mimi, who nodded encouragingly, her hand on his knee. “It’s okay, baby. Mom’s the best. Trust her.” Swallowing his pride, Tae nodded, standing awkwardly as Koo led him to the exam table in the corner, disguised as a leather chaise. “Lie down, dear,” Koo said smoothly, her voice like honey. She slipped on a pair of latex gloves for show, snapping them against her wrists, her huge tits jiggling with the motion.

Mimi sat nearby, watching supportively as Koo helped Tae unbuckle his belt, her manicured fingers brushing his skin. Tae’s heart pounded, embarrassment flooding him as she tugged his pants and boxers down, exposing his thick, heavy cock. It lay soft against his thigh—massive even flaccid, veiny and girthy, the head plump and pink. Koo’s mouth watered instantly, her full lips parting in a silent gasp. Holy fuck, she thought—that thing was a beast, longer and thicker than any she’d seen in her slutty escapades. Her pussy throbbed, juices trickling down her thighs under her dress. She could imagine it stretching her fat cunt wide, pounding her senseless. But with Mimi here? She had to play it professional.

“Alright, just a standard check,” Koo murmured, her gloved hand wrapping around his shaft. It was warm, heavy in her palm, and she stroked lightly—up and down, as if measuring, her thumb grazing the underside. Tae groaned softly, his face flushed crimson. “S-sorry,” he muttered, mortified, but to his shock, his cock stirred—a light hardness building, veins pulsing under her touch. Koo’s pussy clenched hard, her clit aching, wetness soaking her inner thighs. God, she wanted to drop to her knees and suck that monster dry, feel it harden in her throat. But restraint—barely.

She pulled back, zipping him up with a professional nod. “Well, it’s clear there’s potential. You respond to stimulation, but we need targeted treatment. For it to be effective, though, sessions should be one-on-one. No distractions.” Mimi nodded eagerly. “Of course, Mom. Whatever it takes.” Koo smiled, her eyes lingering on Tae’s crotch. “Come back tomorrow, Tae. Alone. We’ll start then.”

They left soon after, Mimi chattering hopefully, Tae still reeling from the touch that had sparked something in him. Back in her office, Koo locked the door, her body on fire. She hiked up her dress, spreading her legs wide on her desk, her fat pink pussy exposed—lips swollen, glistening with arousal, clit peeking out like a needy pearl. “Fuck,” she moaned, two fingers plunging into her soaked hole, imagining Tae’s massive cock instead. She fingered herself roughly, her free hand squeezing her huge tit, pinching the nipple hard. “That big dick… my son-in-law’s monster cock… gonna make it hard for Mommy, aren’t you?” Her walls clenched around her fingers, juices squirting as she rubbed her clit in circles, visions of riding him, her tits bouncing, ass slamming down, his cum flooding her womb. She came hard, back arching, a guttural cry escaping her lips, pussy gushing over her hand. Panting, she licked her fingers clean, already plotting tomorrow’s “therapy.”
