~~~ The Trip Home (continued) ~~~
At the hotel, that night, my sister slept in my bed - leaving mom to sleep by herself. We didn't fool around - well - other than kissing a little. I whispered to Melli that I thought she did a really good job of talking mom through her fears. We had both remained clothed as we climbed into bed together, but she pulled my hand into the gap between her legs and kissed my cheek when I wriggled my fingers against her cloth-covered cunt. She kissed the life out of me and then we snuggled together and fell asleep.
The next morning, mom surprised the hell out of me by trading me seats. When I asked her why she'd switched, she said it was because Melli had told her to watch us. She told me that it would be easier to watch from the back.
As I drove, I held my sister's hand and we chattered at each other about school, plans for Christmas and the Easter break, and Wyoming. We talked about adding onto Aunt Kimi's house and what other rooms the addition should have. We decided that one bathroom for the three of us wasn't going to work. Aunt Kimi had her own but the one in the hallway was too cramped.
The miles disappeared and - by the time we pulled into the house - my sister had a rough sketch on her tablet of what we thought we wanted to build. We ended up deciding on a second building - with a breezeway to join the two - linking them at the back deck where the hot tub sat. This would let us get to, and leave, the tub without worrying about anybody seeing. It would also let us put a bathroom right next to the tub so that we could manage potty-breaks easier. If we had visitors, it would also give them a closer place to change clothes - and avoid wet carpet in the hallway when people were changing back. Beyond the new bathroom, but on the same side of the hall, would be a second family room. On the other side of the hallway would be my bedroom as well as a guest bedroom. We sent the sketch off to Aunt Kimi and - by the time we had our bags unloaded and the laundry started - mom's sister had replied back that the two of them liked the idea. She texted me to tell me to start building a list of supplies. I reminded her that I worked at a lumberyard. I would run the sketches by the boss and - by the time Melli and I were ready to move to Wyoming - I would have everything delivered so that we could start construction.
"Come here, you two," mom said.
Melli and I stepped over to see what she wanted. She took one of our hands in each of hers. My sister and I automatically linked our hands to complete the circle.
"I'm just going to tell you right now that you two are scaring the loving hell out of me," she said. "My two kiddos are turning into adults in front of my eyes. I'm still going to be watching but I'm starting to believe that my little girl might be a genius and I never realized it."
"Mom," Melli said.
"You two don't sound like you're drunk on lust - you sound like two people planning for their future together. I am so excited and scared at the same time. I'm not sure I'll be able to sleep tonight."
"We'll sleep in your bed," Melli told her. "We'll wrap you up so you don't have to worry. You've had a lot of time off of work and we switched time-zones so you're gonna be trashed at work tomorrow."
"See?" Mom said. "Who are you - and what have you done with my daughter?!"
Melli laughed and wrapped mom in a hug. Since we were holding hands, that movement brought me into the circle as well. I wrapped my arms around both of them and gave a little squeeze.
"This isn't happening," mom said, sounding close to tears.
"You can come with us, mom," Melli told her.
"Now I know I'm insane," mom said.
"I'm serious," my sister told her. "You've got a few months to plan. Hell, we'll move out and get the new addition built. You wrap things up here, sell the house, and we'll have a place for you when you get there."
"I'm not ready to retire yet," mom said.
"Who said anything about retiring? You'll just be changing from what you're doing now to helping keep the other four of us out of trouble - you're getting promoted to manager."
Mom hugged her and kissed her cheek and said, "Okay, you're too much. Get to bed and we'll talk later."
I changed into my bed clothes and ended up meeting Melli in the bathroom. I brushed my teeth, peed, and washed my hands.
"Ready?" she asked me.
I smiled and nodded.
We knocked on mom's door, carrying our favorite pillows. When she asked what we wanted, we slipped inside, closed the door, and climbed into bed with her.
"You're fucking kidding me," she gasped.
"Language," I said, laughing.
She hugged our necks and then laughed as we snuggled in on either side of her to hold her as we fell asleep together.
~~~ The Watching ~~~
Over the next four weeks, my sister and I maintained what we'd already been doing - at least as far as having sex when mom wasn't aware.
