"Hehe~ it seems Alice needs more training. Mom will have to satisfy Kars instead."
Shinki climbed back onto Kars. Once his cock was back in her pussy, she began a rapid, rhythmic grinding.
"Aah~ Kars... Mom's pussy feels better, right? Doesn't it feel great to be back 'home'?"
"Mmm, Mom's pussy is definitely warm and cozy. It really does feel like coming home."
Shinki's smile widened. "You really are Mom's favorite child! I'm so happy to have you!"
Alice, however, was miserable. Having been forced into an early climax and then losing her spot again, her frustration peaked. Kars noticed her expression and decided he couldn't ignore her. He reached out and touched Alice's pussy.
Alice thought he was just going to finger her, but then she felt a familiar, hard cock press against her opening.
"This... this is your cock, Kars!?"
"Eh? Alice grew a cock too!"
Both Alice and Shinki were stunned, staring at the second phallus Kars had manifested via his magic.
"Since Alice can't play with me directly right now, she can play with Mom alongside me. Look, Mom's asshole and mouth are still free."
Following Kars's suggestion, Alice moved behind Shinki. She aimed her new cock at her mother's tight asshole.
"Wait... wait! Using my ass is... and two at once? I'll definitely... aah~"
Shinki's protest was cut short as Alice thrust her cock into her mother's rectum without mercy. Shinki let out a depraved scream.
"Isn't this better? A lustful woman like you must be thrilled, right? Having both holes worked by identical cocks simultaneously?" Alice began to thrust in sync with Kars. The two cocks pressed against each other through the thin internal walls, giving Shinki an overwhelmingly intense stimulation.
"Aah~ I'm... I'm going to break... Mom's body is being ruined by her two children... but this... this feels too good... Alice, being this intimate with you and Kars... I'm so happy..."
"Mother really will say anything now." Alice wasn't surprised. Shinki was now just a mother whose head was filled with incestuous bliss, thriving on the lewd joy of being used by her children.
"This feels so good... and she adapted so fast." The once-tight asshole was now slick and loose. Alice marveled at her mother's sheer depravity.
"That's because... it's Alice and Kars together! Your love made Mom's body react instantly... I never imagined something like this could happen... if not for Kars... I might never have known..." Shinki hugged Kars's head, pressing her breasts into his face, while Alice's movements from behind caused her tits to deform against him.
"Here it comes! Let's cum together!" Alice and Kars both accelerated. The sensation of the dual thrusting was so intense Shinki felt like she couldn't breathe. With a final, shared scream, both of her holes were filled with semen. When the cocks were withdrawn, thick cum cascaded out of her.
"Keep... keep loving Mom's body with your cocks..." Shinki was now addicted. As she lay on the sofa, Kars continued to fuck her pussy while Alice moved to her mouth, thrusting her cock into Shinki's throat.
"Aah~ her mouth is sucking so hard..." Alice was conquered by Shinki's oral skill. She grabbed Shinki's head and drove her cock deep into her throat until they both ejaculated again, leaving Shinki's body twitching in a massive climax.
Finally, Alice took her turn being fucked by Kars while Shinki sat on her, grinding against her from above. While Alice performed oral on Kars, she moaned with every thrust he made into her pussy, eventually swallowing his cum while Shinki creampied her.
"Let's take a family photo."
At Kars's suggestion, they posed for pictures. The first was Kars standing while Shinki and Alice knelt to lick his cock, both making peace signs at the camera. Then came photos of Kars and Alice "playing" with Shinki, capturing every lewd expression. Finally, a photo of both women kissing Kars's cheeks. They developed the photos and hung them on Alice's wall.
"This finally feels like a real home. A loving family of three is the ultimate happiness," Shinki sighed contentedly as a thick stream of semen trickled down her thigh.
