"Hello, little girl," I said. "You're awake." You are, too," she said, kissing me. "Let's get dressed and see what's going on around the house."Almost...reluctantly I got dressed, still feeling a warm glow in my groin from the wondrous activity there an hour or so before. We were both clad in jeans and sweatshirts and we walked downstairs and outside for a stroll around the grounds. The walk felt good, as did the small hand in mine, and the private moment together under the umbrella of the pine. As her hand movement become more frantic, her thighs part allowing greater movement. I know she is awake when her spare hand finds my dick. She leans towards my dick and I hear and feel her spit on it! And not the blowjob I had hoped.Without a word of good morning she pushes my hips over so that I’m flat on my back. Almost jumping up she impales herself on it. Then in true horsewoman style she fucks me hard at the gallop. Her tits bounce wildly before she holds them tight. Shame. “Come on stud. Ducks, almost always Mallard. Coot. Cormorant. Gulls.The first thing I saw was the brown, crested head of a female merganser, with a retinue of chicks. Mergansers are not ducks, though they look like it. I pointed them out to Dora, and offered her my compact binoculars.While she was peering through them, I saw the shape I was hoping for, and touched her shoulder.“What is it?”I pointed. The bird was some distance away, and if I hadn’t known what to look for I wouldn’t have noticed it. “Osprey,”. And my heart was beating like crazy to see my own sister playing with herself in such a sexy way. I bit my lip, trying to keep silent as I watched, lest my big sister hear me and be angry that I was in there, embarrassed that she was giving me such an intimate show. I was very aroused, my own little nipples hard, my pussy wet, and I realized I was aching to touch herm my own hot fucking sister. I put the heel of my right hand against my clit over my tight jean shorts and began grinding down on.
