I planted a big, wet kiss on her labia, making my sister gasp softly. I spread my gently kisses all over her outer lips, just as she had always instru...ted me. I began to lap upward along her fragrant slit, allowing my tongue to invade deeper with each pass. Penny did not like to be rushed, so I took my time. This was not a problem for me because I loved to dive into her luscious muff. Slowly, I pushed a finger into her depths, massaging the slippery interior of her tight vagina. My sister's. I’d spent the summer happily discovering her body. The softness of her skin, the curve of her neck and the scent that was distinctly hers, were all mine to memorize. I took pleasure in each delight she had to offer and did my best to offer her my own. Bardhini was a quick study. Her sexuality suppressed for so long, she was a veritable fountain of horniness. Eager to make up for time she only thought she had lost, she embraced all the secrets of sex that I had to offer. Clearly she was going to. We traversed a strange circular area with a sort of glassy look to the terrain. It reminded me of a plate with a hard brittle surface. It was not yielding to the touch and I had the feeling it was the result of some long ago high heat that melted it all together into a consistency that refused to absorb any liquid and didn’t crack from the weight of either two footed or four footed creatures. In fact, our wagons passed over it with no sign of passage and that convinced me the oddity was either. With that she started kissing me deep and frenzied, I tried to keep up but I was still in shock and my arms hung limply at my sides. “Come with me” She commanded and I followed into the bedroom “ Take your clothes off, you’ve seen my body I want to see yours” I fumbled around pulling off trousers, shirt and socks then stood in front of her in my boxers. ”You’re hopeless let me help” Before I knew what was happening she had yanked them down exposing my throbbing cock. “Wonderful” She grasped it.
