You, and Isaac walked to the cave, and got there that evening. You introduced Isaac, and told Andrew, and Natalie to build a nest for you, and Isaac to share, and they obeyed finishing within 2 hours. You took Isaac to the nest, and asked Andrew, and Natalie about their task. "Mistress we did as you asked, and discretely tranfomed 18 humans into random mythical creatures, and animals, but all the same gender as you." Andrew said, and Natalie followed up,"We also made them completely loyal to you, and have been sent to find isolated caves, and breed with the ones that matched their species my mistress." "Good now you may make your own quarters here, but don't mate until your second mistress Isaac, and myself breed. You will then take care of us, and continue transforming anyone who sees you, until our young awaken starting tomorrow, and my new name is Shade us it and adress me as Mistress Shade. Do you understand what you have to do pets?" You said. "We will build a nest here for us, and then take care of you, and Mistress Isaac until your young have awakened, and if we have any complications with humans we transform them into your subjects Mistress Shade." Natalie said. "Good, now can you give your mistresses some alone time we must have our privacy when we perform such actions." You said, and the two nodded, and said in unison,"Yes, Mistress Shade." Andrew, and Natalie left as you turn towards Isaac. "They seem nice." Isaac said walking up to you. "Well I have to be strict, because they at first tried to resist, so I used Natalie as an example, and turned her female, as for Andrew he chose to be male." You explained leading Isaac to your nest. "So who's going to play mother, and who's going to play father my love?" Isaac asked,"Why don't we play both sides, and share this experience with our children when they do this later on, besides I wouldn't want only you to experience childbirth." You said.
Isaac nodded presenting hirself, and you shoved one of your dicks into hir pussy to get the space relaxed. As you did shi squeezed your breasts and you did hirs thrusting into hir, and inserting your other penis into her pussy, and you both climaxed cum shooting out of Isaacs penises, and dripped from your pussy when you did. Then it was Isaac's turn for penetration, and shi came up from behind pinning you to the ground as shi fucked you. You felt hir penises thrusting as shi vigorously squeezed your breasts, and your nipples ever so gently as you both climaxed once again. "Can we try something weird my love?" You asked,"We're already passed weird my love, and I want to go beyond the definition." Isaac responded. You told Isaac to copy you and shi did as you inserted one of your penises into her pussy and shi did the same to you. Then you proceeded to put Isaac's other cock into your mouth, and Isaac got the idea immediately after as you both sucked each other's cocks, while fucking each other with your other cocks. The two of you cummed and stopped once the two of you did cum. "That was the best feeling in my life, Shade can we do this again my love." Isaac said catching hir breath. "Maybe so, but we must tend to our brood, our children, and our empire." You said,"Besides we always have each other."
