"Hey Jeff can I sit down and see the options of the Chronivac?"
"Sure Jenny. I will watch over your shoulder and you can tell me what you are doing." As Jeff was saying this, he was getting of his chair to allow Jenny to sit.
Once Jenny sat and was looking at the computer, she began to check the options available to her. "Hey Jeff to tell you the truth I have a breeding kink."
"Huh, were is this coming from Jenny?"
"Well seeing the options I want to make my dreams come true. I always dreamt of turning into a Hellhound monster-girl and getting railed by you, till you knocked me up."
Jeff was blushing at his girlfriend's words and her notice she was blushing as well. He decided to tease her only a tiny bit. "What else happens in you dream." He of course wasn't expecting her response.
"Weeelllll.... In my dreams our families are swapped......... Your dad Gabriel is my mom and a sexy Dragon-girl, your mom Emily is my other mom and she's a Hellcat monster-girl and you 12 year old little sister Claire is my sister and a bimbo fairy........ We, you also fuck in pairs You, I fuck you dad, while your mom and sister fuck together. You fuck me and you dad together knocking us up, then go on to fuck your mom and little sister knocking them up.... you always knock us up in a threesome."
Jeff was in shock he didn't expect Jenny to come out like that. But the more he thought of her dream the more it turned him on. And the more he actually felt it was okay to do, but he did have one question on his mind.
"Why do I fuck you and my father together?"
"Well when you can't come over to fill us with your loads, I have sex with you father. That's why we fuck as a pair."
Jeff thought it over and guessed it made sense, it would be hard to come over every day. Jeff realized he felt surprisingly okay about knocking up his family and girlfriend, but he just realized a big issue.
"What about all the children i would have with you? I'm not ready to be a dad."
"Don't worry I thought of that, while I was checking the Chronivac. The children and the world wouldn't recognize you as the father so you won't have any responsibilities. While in my dreams I always dream of having a bigger and bigger family of monster-girls, being the Goddess-Queen-Mother to all Hellhound-girls, having incestual relationships with them and all of us living in an infinitely expanding house to hold all the children. What can I say I really want to be a very fertile mother."
Jeff now found himself a bit speechless. He at the moment didn't know what to think. After a few seconds, he knew this is what his girlfriend really wanted and what he wants is to make her happy. So he figured if this is what makes her happy then he should support her and give her what she wants.
"Okay Jenny, then lets do like that. Let's do what you want."
"Really Jeff, you are okay with this?"
"Ya, who can't say no to railing his girlfriend."
"I love you Jeff. You are the best."
With that Jenny got to working on choosing the body shapes of her soon to be family.
Gabriel would be a 6'5" tall, Dragon-girl, with a perfect muscular Venus body type, (A female body type with hips that are exceptionally wide, thick thighs, huge breasts, and a sagging belly that doesn't cover the pubic mound. Very loosely based on the Venus Anadyomene, the classical portrayal of the goddess Venus/Aphrodite.) and would always look like a 30 year old
Emily would be a 5'3" Hellcat-girl with a fertility goddess body type and would always look like 30 year old.
Jenny/herself would be a 5'11" Hellhound-girl with a muscular body type and DD-cup tits and always look like a 16 year old
Claire would be a 3'4" fairy with a bimbo body type and would always look like a 12 year old.
Jeff would be a 5'7" human male with his current body type and a 9" cock.
Jenny then went on to choose their relationships with each other and their fertility.
Gabriel would be Jenny's birthing mother and sex partner (have sex with each other and fuck Jeff together.) and lay 12 egg per pregnancies.
Emily would be Jenny's second mother/birthing father and would be sex partner's with Claire. She would lay a litter of 5 per pregnancies.
Claire would be Jenny's little sister, mothered by Gabriel and fathered by Emily. Claire is Emily's sex partner and gives birth to triplets per pregnancies.
Jenny is Gabriel's sex partner and gives birth to litters of 5-6 per pregnancies.
Jeff is the only one who can fuck the family and knock them up.
Gabriel's pregnancies caused by Emily was caused by a miracle, since Jeff wasn't there to knock them up yet.
"Done" Jenny said smiling from ear to ear.
"What about Gabriel's name? aren't you going to change it to something fitting for a woman?"
"No, actually I want Gabriel to be the only ones besides us to remember. But I will change his mind to remember me being his daughter instead of you being his son, Jeff."
"Why?"
"I think this would make sex more interesting."
"Okay if that is what you want."
"Thank you Babe."
"Now, time to make these changes a reality."
