“How are you doing Dora?” Dorothy asked in concern as he daughter lay on her side moaning lightly. Her bulging midsection shifted as Roger moved inside her, inciting more moans from the slutty piglet. Licking her lips, Dora weakly sat up, moving her hand over her expanded midsection slowly. Then she smiled at her mother with all the joy she could muster.

“I feel like I just got fucked up the ass by a horse,” she vulgarly exclaimed, giggling happily as her body groaned at the pressure her insides were going through. Dorothy nodded, knowing that Dora was doing just fine. She had been afraid that Roger would be too much for the young girl’s body to handle. She could swallow Roger and then some, but her body was made of metal and advanced rubbers. The human body could only stretch so much.

“Mommy,” Dora began, slowly lifting her head up and staring longingly at her mother. Wiggling her hips, her ass cheeks smacked together loudly. “My ass is still hungry.”

It took Dorothy several seconds to understand what her daughter wanted and it was something the android wanted as well. She had wanted to play with her daughter’s fat ass ever since she saw it wiggle in front of her. Now, she was going to be eaten by the blubbery rump. “Then you better make room because mommy is coming in.”

Dora giggled and lifted her ass back in the air, wiggling it around invitingly for her mother. Dorothy moved fast, wanting to get close to the fat rump now. Behind her daughter, she eyed her ass as it jiggled provokingly at her. Her beautiful, firm ass was pushed into the air, round, bare and waiting for her to enter. Without a second thought, Dorothy pushed her face into the crack. She stared at the puffy anus in the shadow of Dora’s ass cheeks. Needing to get a taste before she plunged in, Dorothy ran her done from the bottom of Dora’s pussy to the end of her ass crack. A deep moan shook the cellulite cheeks around Dorothy’s head.

“Mommy Please! I Need It!” Dora screamed as her pussy squirted out juices on the sheets. Hearing her baby’s cries, Dorothy pushed her face in, shoving her whole skull in past the rubbery sphincter. A loud moan shook Dora as her mother squirmed her head into her backdoor, not stopping until her shoulders were rubbing against the sides of her expanded ass hole.

Dorothy breathed in the musky, foul scent. When Dora had been a baby, Dorothy hated her dirty diapers because of the smell, but now that her baby was a sexy fat slut, the smell of shit was a turn on. The things that change where a girl becomes a slut.
Twisting her shoulders into the rectum, Dorothy began the journey in, hearing wet, squishing sounds as she made her way past the anus. Her nipples brushed against the strained hole, sending pleasure through her own body. Dorothy would love right now to have a free hand to play with herself, but her hands were busy. She would just have to try this next time with Roger outside to fuck her. Thinking about Roger and how close she was getting to him, Dorothy squirmed harder, making her way deeper into the bowels of her only child.

“FUCK! FUCK! FUCK! FUCK!!!!!!” Dora screamed herself hoarse, feeling every inch of her mother as it spread her asshole out. She could feel her mother entering and her father deep in her intestines. Having them both inside was like getting fucked up the ass twice at the same time. Holding her swelling belly, Dora took deep hard breaths as her pussy gushed with fresh cum. She felt amazing, incredible and never wanted that feeling to stop.

Dorothy was moving her hips past the anus now, worming her way closer to Roger until she saw his feet just ahead. He was moaning and rubbing himself against the slimy surroundings, lost in his own lust. Dorothy squirmed harder, pulling her legs into Dora with a final slurp. A scream followed the last of Dorothy going in and Dora was left to lie on her belly gasping for air. Inside her, two long time lovers’s reunited.

“You know, we really have a great kid.”

“Don’t I know it.”
