I had tried sort of flashing and being nearly nude around her when the opportunity arose. I would go into her bedroom at night wearing my pyjamas and ...it on her bed talking to her. I would purposely ensure that my pyjama trouser opening was indeed open and that my cock could be seen, she could not fail to see it through the opening of my pyjama trousers. That would be the extent of my sexual activities with my sister, I found these events immensely erotic and I would masterbate fantasising. ------"Johnny, I'm home." She called out as she entered our apartment. "I've just got back from the nail salon. I've had my feet done if you want to have a look."Alice called out to me. I came out the bedroom and into the living room of our small apartment just as she was kicking off her shoes. She wore tight leggings under her skirt showing off her shapely legs.I walked over to her and gave her a peck on the lips. She smiled at me and started to undress. I undressed with her and soon we were. Our tongues found each other and began a dance of fire in my mouth. He pulled his mouth away and began kissing my throat and started working his way down to my breasts. I began rubbing my hands up and down his back, feeling the muscles in his back and shoulders. My nipples were so hard they began to ache waiting for his mouth to find them. While kissing my neck he lowered my arms and slowly slid my sweater off my shoulders and down my arms, leaving it around my wrists. This time he was more. Let me know if you need any help." Again with a wink and a grin. Well, after what seemed like about three seconds I was cleaning myself up. I tucked my now tired self back between my legs, pulled up my panties, and walked back out to meet Stacey. She had already gatherer a bunch of stuff up and had a dressing room full and waiting."Feel better now?" she asked. She looked down to see that I had tucked myself back. "Looks good, is it still there?" she said, as she reached out and patted my new.
