A few moments later, Okarun slumped on the table and wept.
"Please just kill me... I can't marry anymore." He cried out bitterly.
"Granny Seiko, what should we do now?"
Ignoring Okarun, Jin asked Seiko about their next course of action concerning the cursed teen boy. She thought for a second, nodding slightly, "We need to exorcise the little worm on his backside. But we're all tired already, so let's do it tomorrow. You also want the reward tonight, don't you, Jiji?"
Jin blushed a little before replying, "Well, yeah."
Following that, they continued to eat while Seiko explained to Okarun what exactly happened and why his balls disappeared again despite supposedly having broken the curse earlier.
Finally, the day ended and Okarun returned home. Momo felt drained and went to the second floor, leaving only Jin and Seiko.
"Now no one is here." Granny Seiko took off her jacket and threw it aside, leaving her in a cardigan with only three lower buttons properly closed.
Two gigantic mountains could be seen through her open cleavage and loose clothes.
Jin licked his lips hungrily.
Despite his calm exterior, deep down his inner self burned with passion yearning for the beautiful mature woman before him. He unconsciously transformed and grabbed Seiko's chin.
"What a hot girl." He said seductively with a grin plastered across a handsome visage belonging to Nurarihyon, "I did try to flirt with you, granny. But I don't think you would make an advance like this."
"Don't get cocky, boy. You're 50 years faster if you think you can seduce me. I am not seduced, you fell for me first."
"I know, you sexy woman."
"Not bad. You've become even smarter when transforming."
Their faces were close to each other.
Seiko's sweet smell wafted past Jin's nostrils causing him to inhale deeply through nose while savoring the scent emanating from the voluptuous figure standing right before him now.
The air around them seemed to grow thick with tension; both parties were clearly aware where things led next if this kept up.
Their lips met midair halfway between them, mouths locking together passionately, tongues intertwining eagerly seeking each other out within warm caverns contained therein.
Wet slurping sounds permeated the otherwise silent room, accompanied solely by soft gasps emitted in between.
'Is kissing always feel this good?' Jin thought and closed his eyes enjoying his first kiss.
Not wanting to lose, Seiko sucked harder onto Jin's lips, pressing against him firmly using entire body weight. Her hands meanwhile roamed freely across muscular chest, feeling toned abs beneath smooth skin.
Unable to match such ferocity initially, Jin soon fell onto the futon with granny Seiko straddling him. She pulled her hair tie, letting the white hair flow naturally over her shoulder.
Still keeping her eyes locked upon Jin lying prone underneath her weighty bosom resting atop his torso, Seiko slowly undid remaining buttons holding her clothing intact exposing ample assets beneath fabric that only concealed the important part.
"Wow." Jin whistled as two peaks freed themselves from the clothing.
"Don't 'Wow' me, boy. I know how good I look." Saying this proudly, she leaned forward until her face hovered inches apart from Jin's own staring intently upward towards hers waiting expectantly.
Suddenly, she planted another fierce smooch upon unsuspecting youth beneath her overwhelming frame, kissing feverishly and deeply plunging her tongue straight inside his gaping maw.
Unable to keep pace initially, Jin tried his best to fend off attacks delivered by Seiko's eagerly. He moved his hand across her unexpectedly smooth skin, resting them on her large bosom, fondling her tits firmly. Inevitably muffled moans escaped Seiko's lips alongside saliva pooling out corners of her mouth as pleasure flooded her senses.
But it didn't last long however, as Seiko began pushing his head backwards, pinning him down forcefully against floorboards underneath him. She then proceeded to grind herself downwards onto his groin area rubbing herself roughly across hardness concealed beneath his pants.
She raised her body slightly and pulled his pants down, freeing his rock hard penis.
"Ah..."
Feeling it pulsating against her entrance, she breathed sharply.
"How is it? Way bigger than Okarun's, no?" Jin smirked.
"Don't compare your thing to that child. And no, this size is common."
But then her smile turned into a naughty smirk. "But to take it fully is extraordinary. Are you sure you can handle this?"
"Try me."
As soon as the words left his lips however, Seiko descended swiftly driving his length deep inside her passage.
"Hnn!"
His dick reached the deepest part at once, eliciting gasps of ecstasy escaping Seiko's lips uncontrollably. Her walls squeezed around thick organs intruding her moist folds, tightly gripping Jin's whole girth.
'Fuck.' Jin gritted teeth, clenching shut struggling to retain sanity amidst an onslaught of sensations assaulting the brain simultaneously.
Pleasure coursed through his veins, his cock pulsated inside the sexy woman's folds. Still straddling atop him, Seiko stared down at him, her face flushed crimson red.
"Hha~n.."
With another grunt of exertion escaping Seiko's throat, her hips descended further down. Jin didn't stay silent either though. He grabbed her perky ass cheeks harshly, guiding movement of plump bottom gliding upwards till only tip remained inside before repeating motion all over again.
Slapping noise echoed throughout the room punctuated by wet squelches produced during repeated thrusting motions.
As their intercourse went on unabated, beads of sweat trickled down their foreheads, engaging in passionate acts together.
"Aaahn~~~! Fuck...Haa...Is this the best you can do, boy?!"
Seiko moaned loudly, writhing wildly atop Jin. She ground herself roughly against the base of the stiff pole, raised her hips before taking everything inside her repeatedly.
Jin grabbed her bouncing tits while thrusting up. This stimulated Seiko greatly, making her scream. They were both approaching their peak.
"Fuck, you're so tight. What a fine piece of ass."
"You're still talking cocky. I'm going to milk you dry."
And just as she said, she tightened her grip on Jin. Her lips curled into triumphant grin seeing Jin groaning weakly beneath her onslaught. However, instead of retaliating immediately afterwards, Jin merely grinned broadly back.
With firm grip still affixed firmly atop her round bottom, Jin thrust upwards hard, pushing deeper inside.
"Hnn!"
A loud gasp of surprise escaped Seiko's mouth as his length plunged further inside.
"Not yet!"
Instead of stopping however, he continued pounding away furiously ramming himself repeatedly upwards without mercy.
"Haa—! Wait— Aaahhhhn!"
Moaning nonstop in tune with Jin's relentless pounding, Seiko bounced atop him frantically, moving herself in sync with each powerful lunge delivered by Jin underneath her.
Before long, her pussy contracted violently, milking Jin's swollen cock inside. Feeling climax nearing, he pulled his cock out at the very last moment before spraying streams of cum everywhere.
Thick ropes flew through the air landing on Seiko's stomach, coating her belly button with viscous fluids. She grabbed the cock and moved her hand up and down while fondling his testicles, coaxing every drop from his spent shaft.
After everything was done, Seiko raised her cum covered hand and licked it.
"That's it for your reward, boy."
Her tongue lapped against palm and fingers coated with semen, cleaning thoroughly with lewd expression apparent throughout the process.
Watching this made Jin hard again, but she already moved away, fixed her clothing, and lit a cigarette. Her smug smile never disappeared though.
"Good boy. That's a lot of nutrients from you. If you are still eager, do something that makes me want to reward you again."
With that said, Seiko exited the room.
"The shower is yours. You better clean up nicely and air your room, or I'm throwing you back to your cursed house."
"Yes, ma'am." He answered, undid his transformation, and laughed.
