Sandra hesitated and then took a sip. It was sweet and made her feel warm. She took another sip and then drank it all. “Now Sandra this doll is used...for pleasure” he began “it has magic powers and gives pleasure to whoever holds it”. Sandra looked surprised “how do you know my name?” she asked even as she felt herself getting warmer. Ed didn’t reply. He just looked at her. “I feel so hot” Sandra said “what was in that drink?” “Don’t worry my dear. Now press the doll in the stomach” he said. She. Instead of belting back to bed, I paused outside my sister's room. A wild thought gripped me, and I fantasized for just a moment, before deciding that I knew what I wanted to do. I ran quietly and quickly back downstairs, hopefully before my little sister could make it back in the house. I underestimated her, apparently. As I slunk into the sitting room she tiptoed back upstairs. I shifted position to see her gorgeous ass creep upstairs. She had no breasts to speak of, nor any pussy hair. She was prepping her mouth for my cock. I blocked out for a few seconds how many dicks may have been in her mouth that day, that week. It didn't matter in that second. She propped herself up on one elbow and her full lips surrounded my cock head. This was an expert mouth. Her tongue dominated underneath my shaft while her wet lips engulfed the head with a wonderfully tight grip. I drifted between closing my eyes in ecstasy and reminding myself that this was an experience not to be missed, watch. She laughed and said, "I'll just go and leave this film in to be developed." I tried to catch her but the new 4" heels I had been practicing in proved too much and I ended up tripping over her suitcase in the hallway, landing flat on my stomach, with my skirt riding up as I watched the front door slam shut.Now, neither of us had a secret!When Karen came back about a half hour later I was dressed in slacks and T-shirt. The makeup was washed off and the clothes stashed away in their hiding place..
