Moving inside I see Sunny curled up on a warm blanket in front of the fire. She has on a very sexy negligee as I sit cross legged. Her eyes bright and... mouth smiling as she looks up to me. I love how her breasts and nipples show through her silky top, and I see her thong is wet as her full lips press against it. I slowly undress down to my briefs, bulging now as I lean down to kiss her. Her kiss is amazing; the feeling of her lips and her warm wet mouth tastes so good. I love how our tongues. 18 years old and she was better looking than any 22 year old I ever knew. Her nipples were starting to poke out a little too and she looked freshly shaven. I couldn"t believe how sexy my little sister was looking right now. She was the one to break the silence by saying,"So are you just getting in or about to get out?" I got a little gutsy and said,"I just got in but you can join me if you want." "I think I will actually." she replied. So she stepped in the shower and I swapped ends with her so. Her panties were wet like hell. She was dripping a lot. I whispered in her ears, “ do you want me to take of ur panties” and she moaned and said, do what ever you want, and she said, she was waiting for this moment for long time. I took off her panties and she pulled my shorts down, I was naked in front of her and she was naked too. She came closer to me as my dick touched her pussy. She started to move her pussy against my dick and she gave her boobs to me to suck them hard. I moved my hands. We had a small blackboard and river caulk to learn to print, and later to write in the flowing cursive style both our parents used. My siblings could already read and write, but they needed to learn mathematics, science, geography, and history to be as knowledgeable as adults.Dad taught me how to cipher from the time I was five or six. He was always using a stick on the ground to show me how to add, subtract, multiply, and divide. He said that you had to use numbers and fractions to know how.
