I've always been close to my two brothers not so much my sisters until this day.As I walked outside to the pool I saw a sight and a half my youngest s...ster in a blue two piece swim suit (for privacy reasons ill call her casey) anyway she is only 10 but already stood 5 foot and mostly legs she had a firm ass and nice full a cup breasts. She has long strawberry blonde hair and green eyes. As I stood there looking at her I simply said to her " that swimsuit looks very nice". She looked at me and. "Then you don't get to cum." She winked, knowing who was in control.I was trapped, and I knew it. " It's yours to do with as you wish", I said, resigned to the fact that I had no bargaining power. Using her own pussy juices, Marnie jacked my shaft vigorously until I moaned, "I'm.. I'm cumming!" My cock errupted and warm cum slid down my shaft, over Marnies hand and onto my balls. Marnie licked up the creamy sauce, turned to Morgan. The gleam in my grand-daughters eyes indicated how willing she. After I was happy he was lubed up enough, I slowly started to push the dildo into his tight little asshole. He started to move his hands to push me away which resulted in me slapping his ass, HARD. "You can use your hands to hold your ass open slut, and nothing else." I commanded. He held his ass wide open for me, and I continued to push with the dildo until the tip popped inside his super tight hole. He instantly started whining and squirming, crying for me to go easy on him. "Don't worry. .."I am called Master here this is my domain and here I rule do you understand Lynnette?" I said "Yes sir I do!" He smiled and said "Reach for the legs and hold on to them I did and he put velcro restraints on me he said "Place your feet on either side of the back legs and he strapped me down there as well I was in complete submission I could not move an inch and he then turned on the television screen and there in front of me was me I filled the viewing area like a movie star on the silver.
