To my chargrin I was restrained from expulsion by a butt plug attached to a harness. I was whining as she commanded me to retain this, sharing with me... I would not know for how long, perhaps, she smiled for up to a half-hour and by this time I would be in tears! During all of the above enema injections she chose to give me corporal punishment at the same time! She has well over 100 instruments for this including many leather and the much-hated rubber straps with their inherent accumulative. I watched her pulling softly on her nipples as I licked all around her sex and sank my tongue into her love chute.Then I as felt something strange I nearly yelped out. I looked down to see her little sister had taken my hard cock in her hand and was rubbing it softly over her face; she looked up and put her finger to her lips telling me to be quiet as she then slowly sank her mouth onto my cock taking me into her mouth and sucking gently on me. Jesus I thought one sister I was eating the. "Either they will see you naked or stay in rooms" mom said and I kept quiet. "Now get to bed, you look tired" mom added and headed back to the kitchen while my sister and I quickly made our way to our rooms, careful not to look at each other as we did.I woke up six hours later. My bladder was about to burst, and I was starving. I got out of bed, slipped out of my room and made my way over to the bathroom. Just as I got to it, the door opened, and my sister walked out. She was, of course, naked. ..!"Holly may not have known what was happening to her, but her pussy knew what to do and her juices began flowing in abundance in response to my tongue. I greedily lapped them up almost as fast as she produced them and my tongue, furiously working to capture them all, only made her squirm and wriggle more.Then I pulled another trick out of my bag. Using one side of my face to hold one of her asscheeks in place, I took my now free hand and used my thumb to rub across her exposed and erect.
