Preparing for my journey

What followed that night with my mother was a major dynamic shift in our household. I went from being the Youngest person in the house, with the least amount of power, to being a head of the household. It was like a switch flipped in my mother's head and she became more like a Wife to me then a mother, and Mila was more then happy to fall into a relationship like a second wife, still listening to mom but they both seemed to follow my lead on everything. It was a little jarring to be perfectly honest, its not that I minded having a closer relationship with them, but I don't exactly see myself in a to Dominant position.
Thankfully Mila still prefers to be in charge when it comes to sex, so I still get to enjoy what we had before, but mother very much prefers to be submissive most of the time.
From what Mila has told me, its like Mother has reverted to like how she was when dad was still alive, like I have replaced him in her head. It seems kind of messed up, but Mila keeps telling me that as long as she is happy that I should just let it be. She still calls me by my name, when she isn't calling me Darling or Baby, and has even called me her Baby Boy sometimes when we are having sex, so I at least know that there isn't some major disconnect and she seems to really enjoy this change, even if the process of getting to this point still weights on my mind.

~ 1 week after that night ~

"So... your leaving in about a week right?" Mila says, sitting next to me on the couch.
"Yes... I have everything I need in order to make it to the nearest city so after a week I will head out with Izzy." I say. I see mom leave the room. Every time the topic is brought up she seems to make herself busy with something, not wanting to think about it. I get up and follow her to the kitchen where she starts cleaning. I walk up behind her and wrap my arms around her stomach from behind.
"I won't be gone for long... I promise. I will come home safely as soon as I get over the first hurdle, and once Izzy becomes a full grown dragon it won't be hard at all for me to get home." I say and kiss the back of her neck softly. "You don't need to worry so much. I will miss you to."
I feel mom start shaking a little and I just hold her close. She turns around in my arms and holds me tight and I can feel her silently crying into my shoulder. I just pet the back of her head and let her cry for a bit before she calms down and kisses me deeply. I return the kiss and after a moment we break apart and she lets me lead her into the living room where she sits on my lap.
"Rule 1: You have to come back once a month, and if you can't, then you have to sent word to us about why your late." Mom says with a strict tone in her voice, looking right into my eyes.
"Rule 2: If you are ever late, I get to punish you."
"Rule 3: If you find another girl out there that you want to be with, you must bring her here for my approval first before you start dating them, and then she will join what will probably be some kind of harem, and she has to be okay with sharing you like we are. I will not tolerate anybody trying to take you from me. You can have as many Flings as you want though."
"Rule 4: You need to have a group of people you travel with, no going it alone, even with Izzy this world isn't safe. I know it could take some time to find people, but you need to at least be looking."
"Rule 5: This is the most important rule. Until you put a Baby in me, you need to use some kind of protection with everybody else, like your sister has with those berries she uses. If you come home with a baby mamma before My belly has your child in it, I swear you will not be able to leave this place until we have our baby in my arms and that baby mamma knows her place." She says in a serious voice, sounding like a proper mistress now. I guess she has already determined that I will have a harem and she is putting herself at the very top. Also the thought of putting a baby in my own mother is a major turn on for some reason, I think going through Puberty a 2nd time must have crossed some wires or something, because new Kinks are popping up that I never had in my past life.
I agree to those rules and give her another kiss on the lips before we just snuggle for a while.

~The night before I leave~

Mom and Mila wanted to give me a farewell night of excitement, so here I was waiting in my room. Mila told me to wait for them, naked on my bed, so im doing just that.
After about 20 minutes of waiting the door finally opens and in comes Mila and Mom, wearing nothing but robes that look like are made of a soft animal hide. They walk over to me and Mila pushes me onto my back, climbing onto my chest and sitting on it. Mila and mom remove their robes and mom climbs onto my legs, rubbing herself against my thighs as Mila moves up and puts her pussy in my face, prompting me to start devouring her pussy, my tongue sliding in almost right away to start driving her crazy in the way I knows she likes. Her hand grips my hair and pushes my face against her, making sure I don't pull away, even if she knows I won't. My mother, seeing that my cock is now hard as steel, moves up and starts rubbing the head of my cock against her pussy for a few moments before lowering herself onto it with a deep moan.
I start thrusting my hips up to meet her movements, my tongue going into overdrive in Mila's pussy for a few moments before I focus on sucking and nibbling on her clit, one of my hands moving to slide 3 fingers into her pussy, moving them at the same speed as mom's movements.
It doesn't take long for both of them to cum, with it happening within 10 seconds of each other. I gulp down Mila's cum and lick her clean before she moves and turns around on my chest, giving me a amazing view of her amazing back muscles and her great ass, as she starts making out with mom.
I feel mom move off my dick as Mila starts to slide down my body and slide right onto my cock. Since her back is to me I decide to turn the tables on her and pull her down by the neck, thrusting into her at a fast pace. Its something that I saw in a hentai once and always wanted to try since I started having sex with her, but never got the chance since she has always been in charge. My hips go into overdrive, causing her body to spasm as she grasps at the bed sheets under us, moans flying from her mouth with every staggered breath as my hand has a light hold on her throat. Her pussy is milking me like crazy as in less then 30 seconds of doing this she is already cumming on my cock. I drive her to 3 more consecutive orgasms before finally letting loose my load deep into her pussy.
I let go of her neck and she lies limp on top of me for a few moments before rolling over onto her side and giving me kisses from my chest up to my lips.
"That was hot... but if you surprise me with that again, ill edge you for several hours." She says with a smirk, breathing heavily before giving me a kiss on the cheek.
Mom grabs my hand and pulls me up, and on top of her, her hand then coming up behind my head to pull me into a kiss.
"Breed me son... breed your mommy before you leave." She says, giving me the sexiest look I have ever seen in my life. My cock is instantly hard again as I start to rub it against her pussy, teasing her clit with my cock for a moment before sheathing myself inside her. I start to piston my hips in and out, building speed every few seconds.
I come up with a idea and surround my body with mana, attempting to enhance my movements, and succeeding, as my thrusting starts to get faster and harder then I had been able to before, and its driving my mom crazy. After a few moments I can feel her having a almost non-stop orgasm that lasts for several minutes, her moans mixing with screams of pleasure as she cums her brains out. When I start to feel her run out of energy I thrust all the way in and release the biggest load of cum I have ever released, flooding her ready womb and impregnating her. If that didn't do it then idk what would. After I pull out she passes out with a blissed out look on her face.
Mila pulls me over and kisses me passionately. "When you get back, and after she has that baby, your going to do that same thing with me." She says in a dominant tone "Your going to put a baby in me before any of those other harlots you may find out there. I'm willing to be below mom, but nobody else."
I simply nod and lay back down, pulling Mom over and then pulling Mila down with me so we can snuggle together before passing out.
