Doctor, Doctor I grabbed her by the hair, and yanked her head back quickly, “hey! Suzie exclaimed. Any further words were cut off as I stuffed Jasmines balled up panties into my little sisters mouth. “Mum and dad are just next door, remember, and this could tickle a bit”, I said. Suzie’s mouth was too small to take it all in her mouth easily and it hung out of her mouth, “no, no no,” I said, “that could easily fall out and mum and dad could hear you”. I grabbed the roll of duct tape I had brought and quickly tore a piece off. I then forced Jasmine’s knickers all the way into Suzie's mouth and quickly stuck the tape over her mouth, sealing them in place. I then pulled tight the scarves entwined loosely around her wrists and each leg, binding her hands together, and leaving her tied down on her front, naked on her own bed, with her legs spread wide open and tied to the posts of her bed, utterly unable to help herself or cry out. …. …. I slowly began to push my little finger into Suzie’s tight little pussy. Suzie’s cute little butt wiggled in the air as she struggled and fought to stop me from violating her. I pressed harder, forcing my finger deeper into her pussy, our parents where just next door, but with my Jasmines panties trapped in her mouth, Suzie couldn’t stop me from shoving my finger right inside her tiny hairless pussy while she was tied up and naked on her own bed. Jasmine was laying on the floor, also tied up,with her pyjama bottoms and panties removed, and my rubber hand exercise egg stuffed up her pussy, she looked up at me with pleading eyes, begging me to release her and stop this, I ignored her, I would get back to her pussy later, tonight I had a much to do to them both, and my little sisters pussy was practically untouched. this was the second night in my sister and jasmines sleepover `marathon`, and it was the second time i had violated jasmine, but probably the hundredth time i had violated Suzie in some way, its not like she could stop me when all i wanted was some of her sweets, and she couldn't stop me now from forcefully stripping her and her best friend, in her own room!
