Rio and I sat down in the middle of the hall as we tried to come up with ideas to move the sled around easier. I had quite a few ideas floating around my head myself but I was still not sure if we had the resources to do them or not.

"Sora what about a pulley system? I had seen them being used in Lafina." Rio said after a long silence.

"It would work but it's not efficient with just the two of us and there is no telling how heavy something is. It would be different if I could inscribe some magic runes to assist us but I do not have the materials needed to make magic runes at this time. There is gravity magic that can be used to lighten things or make them heavier but my magic power is not strong enough yet. I can barely use the two mid-level magics, protection and absorb. " I was really depressed that I could not use a lot of the magic spells I had imprinted in my brain...

The two of us were starting to get depressed but a sudden idea came to mind. "Rio you said that the shelf in that room was made of strong metal right?"

"Un! It was very strong even after kicking at it for an hour, it did not even bend." Hearing Rio's words made me a little excited.

"Alright I have an idea then whether or not it will work is another thing. If I use part of this platform to put our sled on then using that shelf to make a wheel and axle system along with some metal cones, we should be able to easily get our sled up an incline and if need be we can set up a pulley system to assist as well. Because if I use my fire magic combined with wind magic I can create thrust to propel the sled. All it would require is me digging down floor to floor from outside the building. If this all works the way I think it should when we find the materials to inscribe magic runes we can make more sleds that work on a magic system I would like to call a magic circuit!" My mind was flowing with ideas at this time. If this all worked the way it should then we would be able to speed out work progress up substantially!

Rio was looking at me with glowing eyes. Before I knew it she had pounced on me and pushed her lips onto mine. Our tongues intertwined as we kissed for a few minutes before our lips parted. Rio moved her mouth next to my ear as she whispered: "Since you will be working the hardest out of all of us I will give you a little recharge." Rio then slipped her hand into my shorts and hooked her finger into my pussy while she continued to kiss me. Her other hand was busy under my shirt massaging my little mounds. I couldn't help but squirm in delight as I let out soft moans.

It was not long before I was on the verge of an orgasm. Rio seemed to have sensed this because she broke our kiss and pulled my shorts down before cupping her mouth over my pussy. As soon as her mouth was on pussy she flicked my clit with her tongue causing me to shiver in pleasure as cummed hard. Streams of my juices flowed into her mouth which she happily drank up. After my orgasm subsided Rio lifted her head and licked her lips and fingers clean. She smiled at me before moving her head back up to mine and planting another kiss on my lips. "Sora remember you are the head of our family so it is the duty of your family to make sure you are fully charged up and ready to go."

"Un! But it is also the duty of the head of the family to make sure her wives are satisfied as well!" After saying that I pinned Rio to the floor as I slowly stripped off every inch of her clothing before using my tongue to taste her entire body. Rio giggled and squealed as I trailed kisses all over her body. Rio's sexy moans had really gotten me horny so I changed our positions so that my pussy was now pushed up against hers. I invaded her mouth with my tongue as I grinded my pussy against hers. After a long while, the pleasure grew to be too much for Rio as she dug her fingernails into my back as I brought her to her orgasm. Just hearing her scream in pleasure caused me to climax as well. I gave Rio another deep kiss before helping her wear her clothes again.

Rio looked up at me and gave me a bright smile. "Sora at the rate we are going, I think you will end up pregnant along with me."

"Doesn't matter! Even if I did become pregnant it will be fine. I will give birth way before you so you will just need to help me during that time." I said with a smile as I pulled Rio into my embrace. "But still it most likely won't happen for a long while. Until then I will need my cute Rio to be an awesome mom for our first baby!"

Rio blushed at my words as she pushed her head into my chest. Squeezing me with her arms that were wrapped around me. "Un! The kids I have with Sora will all be precious little treasures!"

After resting for a bit we went to work. Our plan was to first make the modified sled. Then we would use the current floor we were on as a testing field. Before going to far dawn we were planning to head back home to go through the warehouse as well as creating the tunnel that would lead to and from our home back to the ruins.

This is how Rio and I's ruin excavation really got started.
