My head was swimming with so many scattered thoughts. Here we were, my sister and I, naked, and in her bed. It only took us a few minutes to get to this point, but in some ways, it was many years coming.
Her warm, soft body felt so good pressed up against me. I was in a state of complete relaxation, and also perpetual arousal. I'd never experienced such a thing. While it was amazing, I wasn't sure whether I'd be able to get to sleep. It was so stimulating. It felt like every cell in my body was vibrating. After a few minutes, Michelle's breathing began to get even and slow. I knew she had drifted off to sleep. My own lids began to feel heavy, and it couldn't have been another five minutes before I was out cold. The last thing I remember was tightening my grip on her body.
A few hours later, I woke up feeling parched. I don't know whether it was the two explosive orgasms, or the especially salty pizza, but I felt like I could drink a gallon of water. My dick was semi-hard. I decided to ignore it for the moment.
"Shelly. Baby." I nudged her a bit to see if I could wake her. I didn't want to startle her by leaving her bed. I was worried that she might not be happy if she woke up to an empty bed; I know I'd be pissed off if it were me.
"Yeah?" She was groggy, and I'm not sure she was entirely awake when she answered.
"I'm really thirsty so I'm going to go downstairs and get some water. Do you want anything?"
"Um, yeah. I guess water too." She sat up and began to look around her darkened room. "Have you been sleeping too?"
"Yeah, I've been sleeping too," I whispered. "I've been sleeping really well. I guess I just woke up thirsty."
I slowly pulled myself out of the warmth and comfort of the bed and headed downstairs for our waters. When I came back up, Michelle was in the bathroom. She was sitting on the toilet peeing, and brushing her teeth at the same time. I left her water glass on the edge of the sink.
"Pizza breath," she mumbled through a mouth full of foam.
We were both fully naked, but I suddenly felt like I should be modest. I grabbed a towel and wrapped it around my waist. I began to prepare my toothbrush and brush my teeth, when I heard the toilet flush behind me. A second later, I felt a tug, and off came my towel. I looked over at my sister, who was standing a foot away from me, smirking. My half-hard dick was at full staff, and pointing straight out and up. It was one thing to see each other naked in our darkened bedrooms, but here, in the bright harsh lights of the bathroom, everything seemed so very intense. I finished brushing, spit out the toothpaste, and rinsed out my mouth. Michelle stood behind me, and moved to press her body against the back of mine. I could feel her firm nipples pushing into my back. She reached around to my front and began to fondle my cock. Her grip wasn't as firm or assured as it was earlier. This was more exploration, but very gentle. She was handling me like I was fragile and delicate. She reached with her other hand, and after holding my dick against my stomach, started her exploration on my balls. It felt great and I didn't want her to stop, but her body was slumping hard against my back, and I knew she was tired.
"Do you want to go back to bed?" I asked, looking at our reflections in the mirror.
"Ok. Do you want me to take care of this first? Or just do it there?"
I smiled. It was so strange that the girl I'd been lusting after for so long was here, wanting to attend to my needs.
"I think I can wait a bit. Maybe after we get some sleep."
