We spent much of the afternoon naked. I was on the bed reading while Eric sat in a chair across the bedroom to read. Every now and then, we would look up from our respective books, exchanging a knowing smile or briefly caressing each other with our eyes before returning to our respective tales.
After a while, Eric approached the bed. "How about Reverse Strip Poker?"
That baffled me for a moment, until I realized that since we were both already naked, Reverse Strip Poker would require us both to actually put on clothing.
We played on the wrap-around porch, each of us disappearing inside to put on an article of clothing upon losing a hand. I have never been good at card games, and especially not at poker, so I was quite surprised to still be topless by the time Eric was fully clothed. He stood leaning against the porch railing, holding open his arms, and I stood and joined him, eagerly hugging him even though it reignited the ache in each breast.
I must have made a small sound of discomfort, because he nudged me back and looked directly at my chest, appraising the injuries he had inflicted upon me earlier in the day. He ran a finger around the edge of his bite marks on my left breast, not directly touching the markings but still causing me to hiss slightly.
"Maybe it's a good thing you won the Reverse Strip Poker," my big brother commented softly. "If you were wearing a bra right now, you'd be hurting even more."
I nodded in agreement, watching and hissing as his finger kept making circles around the bite marks. Fortunately, we still had plenty of time to be alone in such an idyllic mountain setting, so far from society, meaning that I could remain topless -- if not completely naked -- for quite some time and allow the imprints of my big brother's teeth to fade away and heal.
Finally, I stepped back, a realization crossing my mind. "You know, we'd better call home, since the cell phones may not work too well way up here."
Eric nodded. We had not yet called our mother, and ideally we needed to call her before she might leave for the evening to enjoy fireworks somewhere.

I remained topless the rest of the day, and my big brother took off his shirt as well -- it was almost as if it was a display of "sympathy" for me, similar to teammates shaving their heads when one of their own has cancer and must undergo chemotherapy. As we made and ate dinner, it was nice to be able to again roam my eyes across Eric's chest, and it made me feel somewhat giddy to watch his eyes alight upon mine.
In the final hour or so of normal daylight, I decided to work on a tan -- not just a regular tan, but a full-body tan. Eric joined me long enough to cover my backside with sunscreen, then retired to the porch to read while I soaked in the warmth of the sun's rays. Even though my breasts were pressed into the ground and many blades of grass were prickling my injured flesh, the aching was quite bearable and served as a wonderful reminder of the lovemaking from earlier in the day. Those thoughts filled my mind, helping to pass the time as my body absorbed the last sunlight of the day, the wetness forming and eventually seeping from me as I relived the pleasure and the pain.
Feeling Eric's hand on my bare back, I slowly rolled over, keeping my eyes closed against the sunlight as he added more suntan lotion to my body. "My little sister seems to be wet," he commented, a tone of approval in his voice. I just smiled slightly, not saying anything -- I knew that nothing needed to be said -- as he continued to rub the lotion into my skin. His touch and his presence and his love encouraged my nipples to harden, and when he at last added lotion to my chest, his palms delighted my nipples and hurt my breasts, causing me to open my eyes at last and look up at him in what was undoubtedly a mixture of desire and distress, yet I did not want him to stop.
...although he soon did, giving me a loving kiss before returning to the porch and leaving me to soak in the sunlight. After a while, I heard my big brother head inside, but thought nothing about it, my mind thinking more about the unusual trajectory of our relationship and wondering whether our living together was indeed the beginning of our unusual relationship, or if it had always been there, percolating under the surface of our sibling status.
