Unfortunately on the third night I must nothave been discrete enough, as one of the other girls in myroom saw me and decided to dob me in to the nurse... forobvious self-abuse.As a consequence, the next day I was put into baby clothesI was unable to take off. These consisted of a rather dullblue dress that came with lockable plastic panties andthick lockable mittens. Miserably I realized that in themI wouldn't have any chance of masturbating or probablydoing much of anything else. The plastic. My eyes still wandered to my sister's sexy naked body. "That is going to far Tara! I won't do it!"She sighed frustrated. "Very well then, I think Chief Davis is working right now and I'm sure he'd love to see the tape-" Fine! Damnit!" I screamed knowing she was in full control.Her face lit up. "Ok now lay down on the bed while I handcuff you to the post," she ordered.I did just that and felt her cuff one hand and then the other. I was there now completely handcuffed to the bed letting my sister. He then began working my asshole with the head of his cock. My eager rear door quickly began to open for him. The cockhead invaded me just less than an inch and the feeling made me let out a very wild pain cry. He was really thick…He smiled and grabbed a tub of Vaseline and began to lube up the rest of his cock. Then he slowly started to push into me. His large cock began penetrating me deep. First it was only two or three inches, then six, eight…, I began to shake and moan but I held sturdy. And I went back to the kiss with Charlie. I thought of it, over and over, her holding my hips, and I her waist, pulling each other closer, and sharing a passionate kiss. After this night I knew I could never be with a man. I thought of tomorrows date. If I could, I would still go. She would know what to say to help me cope with this horrible violation of my body. Before I knew it they both came inside me at the same time, one filled my pussy with his hot load, and as he pulled out hi cum ran.
