Sylvia put her hand on Ann’s shoulder reassuringly. ‘So why don’t you go over there in front of the TV, and when I say go, you start finger fuck...ng yourself,’ she said pointing to the spot in front of the television. Ann walked over to the TV, and stood with her hands at her sides. Josh was horrified. He wanted to help his sister. He was about to stand between Ann and this horrible woman in some vain attempt to stop things, but before he could dash across the room, Sylvia grabbed him firmly by. John was hyper eager, and began pounding away at Sarah’s pussy. Sarah just squealed and bucked as her brother fucked her relentlessly. She felt her pussy moisten, despite her revulsion, but her animal instincts took over, and she began thrusting back onto her brother’s cock. Mother and Father watched their slave children fucking, and decided to encourage them some more. Both picked up riding crops, and began beating John and Sarah on their asses. Both ponies whinnied in pain and. I kicked my legs and cried for all I was worth begging them to stop. Then when they had stopped and I lay across Suzy's lap with the three of them staring at my giggling at my humiliation I knew that I could not win.So I sobbed, "Jennifer, I was a really bad example of a boy. I wasn't strong or assertive. I know how much I should be thanking all of you for letting me become your little cocktease sister. I know I'll be such a good girl with all of your help. Oh, Thank you Jennifer." I managed to. As I slid my hand slowly down his throbbing shaft to cup and massage his huge nut sack, he unbuttoned my night shirt and pushed it off my inflamed body. I moaned against his mouth as his fingers found my straining nipples. Taking the between his thumb and forefinger, first one then the other, he pinched them gently, stretching them, milking them until they grew into hard thimbles of flesh. I had never felt them get so erect, so hard. My nipples throbbed like to fiery-hot coals atop my cooler.
