The rain fell hard that evening, rattling against the wooden walls of the countryside house. Sayaka stood in the kitchen, drying dishes, her huge breasts bouncing gently under her damp blouse as she reached for the shelf.
Her mind had been restless all day. Her body ached, her thighs pressed together whenever she thought of him. She hated it—hated herself. She was a married woman. But she couldn't erase the hunger clawing at her.
When she carried tea to Kawamoto Genzou's room, she tried to calm her breathing.
But the old man's eyes fixed on her curves, burning with need. His cock twitched under the blanket, already hard from just seeing her.
"Sayaka…" His voice cracked, low and pleading. "Please… I can't hold back anymore. Just once… Let me inside you."
Her heart leapt into her throat.
"No… I… I can't…"
She backed away, but her body betrayed her—her nipples pressed against her blouse, hard and aching. Her thighs rubbed together, damp with shameful heat.
He reached out, trembling, clutching her wrist. His hand was rough, desperate.
"Please. Just once. I'll beg you. I'll die happy if I can feel you once."
Sayaka's lips trembled. She should run. She should slap him. But instead, she saw it again—that thick, monstrous cock she had tasted with her mouth, the one that haunted her every night.
Her breath shuddered. Her pussy clenched.
"…Only once," she whispered. "Only this once."

She slipped onto the futon, trembling as Genzou's hands explored her body. His fingers pressed against her blouse, groping her massive breasts, making them jiggle with every squeeze.
Sayaka gasped, arching her back, her face burning red.
"D-don't touch me like that… ahhh—"
But her moans betrayed her.
He tugged at her blouse, and her heavy tits spilled free, nipples swollen and dripping with arousal. The old man groaned, burying his face between them, licking and sucking greedily.
"Such huge… soft tits… ahhh, Sayaka…"
She bit her lip, whimpering as his mouth tugged on her stiff nipples. Her hands trembled as they gripped his hair, torn between pushing him away and pulling him closer.
When his hand slid under her skirt, she gasped. His fingers pressed against her soaked panties, feeling the heat of her pussy.
"No… don't… ohhh—"
But the wetness betrayed her. She was drenched.
Genzou's cock throbbed against her thigh, heavy and hot. Sayaka looked down—and froze.
That twelve-inch beast stood erect, thicker and harder than ever, veins bulging, the tip already leaking precum.
Her pussy clenched just seeing it.
It's too big… it won't fit…
But her body wanted it. Needed it.

He pressed her back gently onto the futon, spreading her thick thighs. Her panties slid aside, revealing her glistening slit.
"Sayaka… forgive me…" he groaned, positioning his cock at her entrance.
Her breath hitched as the fat head pressed against her pussy lips. It was too wide, too thick—her body resisted, stretching painfully as he pushed forward.
"Ahhh! N-no—it's too big!" she cried, clutching his shoulders.
But he didn't stop. Slowly, inch by inch, the monstrous shaft sank into her tight cunt. Her walls clamped around him, stretching, burning, her juices spilling down his cock.
Sayaka screamed into his chest, her tits bouncing wildly as her back arched.
"Ahhh—ahhh! It's tearing me apart—ahhhhhh!"
But beneath the pain was something else. Pleasure. A deep, overwhelming pleasure she had never felt before.
Her pussy clenched greedily, sucking him deeper. Her nails dug into his back as her cries turned into moans.
"Ahhh… ahhh yes… so thick… so deep…"
---
When his full length was finally buried inside her, Sayaka was trembling, tears at the corners of her eyes. Her pussy was stretched to its limit, her belly bulging faintly with the sheer size of him.
Genzou groaned, barely able to hold himself back.
"You're so tight… so wet… ahhh, Sayaka… I can't believe you're mine…"
He began to thrust, slow at first, grinding his fat cock against her walls. Her body jolted with each stroke, her tits bouncing wildly, her ass slapping against the futon.
Sayaka moaned shamelessly now, her head tossing side to side, sweat dripping down her flushed skin.
"Ahhh… ahhh yes… it's too good… I can't… I can't stop…"
Her guilt dissolved into pure, animal lust. Her pussy squelched loudly, dripping wet, clenching tighter with every thrust.
Genzou's pace quickened. His hips slapped against her thick thighs, his cock hammering her cunt deeper and deeper.
Sayaka wrapped her legs around his waist, pulling him closer, begging without words. Her moans grew louder, tears streaking her cheeks as pleasure overwhelmed her.
Finally, her body convulsed, pussy tightening violently around his cock.
"Ahhhhhhhhhh—I'm cumming!" she screamed, her juices gushing, soaking the futon beneath her.
Her huge tits bounced uncontrollably as she writhed in ecstasy, her pussy milking his cock desperately.
Genzou groaned, his balls tightening.
"Sayaka… I'm going to—ahhhh!"
Hot cum exploded inside her, filling her cunt with thick spurts. Sayaka gasped, moaning as the warmth flooded her womb.
Her pussy clenched around him, milking every drop.

When it was over, Sayaka lay trembling beneath him, her body covered in sweat, her tits heaving. She turned her face away, tears sliding down her cheeks.
"…This never happened," she whispered.
But the way her pussy still clenched around his cock, refusing to let go, betrayed her words.
For Sayaka Tanabe, the faithful wife, had taken her first step into betrayal.
And her body was already addicted.
