Sandra was examining the remote when Holly cried for her dinner. Sandra sighed as she put the remote down on the coffee table as she started to take out her tits for breast feeding time. Stew came Sandra came by, and Stew was bouncing around trying to get Sandra's attention.
"Stop Stew, I'm trying to get Holly her food. I'll get you yours in a moment." Sandra said as she went to her portable crib thing to start nursing her little baby girl... And then Stella had to get curious about the remote. She sorta remembered that she had an amazing experience when it showed up but... Stella pressed the button twice not really sure what it was doing when Sandra noticed that instead of a sucking feeling on her breasts she felt a licking motion as her Holly turned into a bitch. A rather horny bitch too as Holly dog leaped out of Sandra's arms in order to start fucking with Stew. "No, Bad boy and bad girl! Stop fucking!" at which point Stew climaxed, and while they were changing back the Sex Machine made a small noise signaling that it could be used again... Which startled the cat which pawed at it again.
Sandra scooped up her baby daughter again and when she started to put her baby daughter to her teat again her teat retreated as her breasts started to shrink into her chest. In fact it kind of felt to her like her whole body was shifting as her estrogen was turning to testosterone, and there was a pressure in her groin as she was growing an already hard penis. Lust began to fill Sandra's mind, and putting her baby down she found a naked girl on her back in a dog's begging position. The girl's breasts big and bare, and her hips were nice and supple. In the haze of lust the sex machine was inducing Sandra lost himself as he jumped on the girl and started to fuck her brains out. Each thrust pure bliss, each knead of the breasts like fluffing a cloud, and once a certain pleasure point was reached Sandra started cumming and cumming hard. He came continuously for half a minute as his dick was shrinking to nothingness and her breasts re-inflated.
"Woo!" Sandra said as Stew turned back into a little dog "Having a dick can be fun!.. Now Stella!" The cat hit the remote twice once more before Sandra swiped it. "There now you can't. OOO!" Sandra felt her breasts and ass swell like balloons as she started going into heat. her wrinkles of older age smoothing out as she youthened into her early twenties.
"Mommy?" a deep voice said behind her, turning around Sandra saw a big muscled man with a rather large stiff package.
"Holly? I..."
"I feel weird. Like when I was a puppy. You look... pretty..."
"...Fuck me..." Sandra said as she dove on top of her once daughter and slowly lowered herself onto Holly's large package, letting her wet pussy engulf it and then lifted and lowered herself on top of the girthy meat stick. The two panting and Holly just enjoying the ride as she saw Sandra thrusting up and down on his dick with her melons just bouncing in front of her. Sandra orgasmed over and over until Holly had enough and spewed his load into the person who was his mother. Then they started panting as Sandra re-aged and her sexual characteristics shrunk. Then Holly's muscles, dick, everything shrank until she was a baby once more unsure of everything she was comprehending. Sandra quickly got off her baby daughter, and then got decent as she got herself a pregnancy test. She waited a day or two before testing, but she for sure was pregnant with her baby daughter's baby. Like Holly she didn't want to abort, and people were starting to wonder how much Sandra was being raped or if it was a repeat offender or someone. However Sandra stood strong, had her second baby, and started smiling thinking about how the sex machine had given her a family.
"What are you going to call your baby boy?" the doctor asked.
"I think I'll call him... wait boy? I thought the other doctor said girl?" Sandra asked
"No, we got the records it was a boy."
"shoot... boy's name boy's name... Ugh... John?"
And thus John was born.
