The movie was hot, in no time I was sporting an erection as over the next hour and a half I watched my sister have sex with various people, both men a...d women. At some point in the movie Jessica moved slightly and I found my hand resting against the side of her breast, while one of her hands rested on my thigh.As the movie ended I looked down at Jessie and our eyes met, and suddenly we were kissing, kissing as lovers, deep and passionate. She twisted towards me and we slid back until I was. Do it. Youwant to, you know you do. Do it. Do it, Karen.” I froze. Her perfume hung in the air like a fog, andher eyes stared deep into mine with an intensity I’dnever seen before. Confused, I held her tighter againstthe wall. “Oh yeah, Karen, do it. Hold me tighter, Karen.” I didn’t know what to think. Tina was ENJOYING this?What is she, perverted or something? She looked like ananimal in heat as she gazed back at me, unblinking. AndI noticed another scent that. Her hand wrapped around my cock, and pushed down on the shaft, toward the base, stretching the skin and inadvertantly touching my engorged head with her forearm.I breathed in sharply. Her eyes did a slow roll up to mine, without her head moving. There was so much lust in her eyes. Her hand was moving forward and backward holding my cock.I was ready to kiss her, but she began a slow kneel to the floor, never taking her eyes from mine. Her look was so sultry. She licked her lips slowly, finally. I quickly showered and changed into my bathing suit, being 55, I stilllooked good in a one-piece suit. I had a bit of a rounded tummy, but mylegs were long, nicely muscled from my daily walks and stationary bikeriding. I was often mistaken for a woman of 40 years of age. Beforeleaving the house, I slipped on a lacy white, beach cover-up, grabbed mytowel and headed out the door."Row", Donna enthusiastically said, when she answered the door, "come in,have some lemonade", she told me as I hugged.
