"Huh? The whole night!?"
In the morning, Reimu looked at her daughter, who appeared completely "broken" and satisfied. The futon was soaked through. Upon learning they had been at it all night, Reimu massaged her temples. It was even more headache-inducing to learn that her daughter had initiated it.
Still, as a mother, she felt she had to scold Kars.
"Can't you show some restraint as a father? You play with different girls every day. Couldn't you have held back a little for your own daughter?"
"...Yeah, I messed up. My bad."
Kars didn't make excuses. He accepted the responsibility and went to wash the soiled bedding. Reimu took their daughter to the bath to clean her up and look after her.
Kars helped out, though his hands weren't idle. He sat behind Reimu, fondling her breasts and rubbing her pussy. Reimu, used to his advances, didn't stop him.
"Don't wake the girl up, you hear me?" Reimu whispered, her breathing already hitching.
"I know. Why don't we go outside and finish this?"
"...Fine."
They stepped out onto the porch and slid the door shut. Reimu's skirt fell to the floor immediately. Her enticing, wide hips swayed before Kars, inviting him to enter her already-soaked hole.
Kars thrust deep, savoring the wet warmth and the familiar grip of her internal walls. His meat throbbed with pleasure.
"Mmph~"
Reimu's expression instantly turned wanton. A blissful smile spread across her flushed face. To keep from waking their daughter, she clamped her hand over her own mouth.
"Alright Reimu, I'm picking up the pace."
Kars began to hammer her ruthlessly. Their bodies slapped together with a loud, wet sound. Wave after wave of pleasure crashed over Reimu. Her eyes widened, and despite her hand, muffled moans escaped her throat. Her tongue poked out, and saliva began to drip through her fingers onto the floor.
Her legs trembled, her toes curling and digging into the wooden floorboards. With every thrust, her knees buckled further until she was kneeling on all fours. Kars mounted her from behind like an animal.
"So... so intense... even more than usual... you spent all night in our daughter's hole, so why are you still this powerful...?"
Kars leaned into her ear. "I couldn't really let loose with her. I had to be careful. Half the time I just stayed inside her without moving. It was exciting, but I had to hold back a lot. Now, as her mother, it's your job to finish what she couldn't handle."
He drove his meat deep into her womb, making her cervix scream with pleasure.
"Ahhh~ I... I understand..."
Reimu's hips shook as her womb repeatedly clamped down on the rod, giving Kars an exquisite sensation.
Through the paper screen of the door, their silhouettes were locked in a rhythmic dance. The noise grew louder, and inside, Little Reimu stirred. However, she was too exhausted to wake up. The sounds seemed to trigger a vivid dream. Her naked body began to flush a deep pink. Her recently cleaned hole became wet once more.
"Mmm~ Daddy... your meat... play with my pussy... it'll feel better than Mommy's..."
Little Reimu rolled over and hugged her futon tight, wedging the fabric between her legs and rubbing her slit against it. The friction in her sleep made her breathing ragged. Finally, she hit a climax in her dream, her body jolting as her juices soaked into the futon she was clutching.
A satisfied smile remained on her sleeping face. She showed no signs of waking up, lost in her lewd fantasy.
Outside, Kars and Reimu continued their session undisturbed all morning. After they finished, they lay together in a heap of post-coital bliss. They eventually turned the entire shrine into their playground, leaving traces of semen in every corner.
