My sister at 5’6, 110 pounds became quite a cutie with sandy brown hair and blue eyes. Her main interest was dancing, and she joined the dance group...at school. I grew up to be 6’2 and 175 pounds with short light brown hair and blue eyes. Mostly I liked to draw and took an interest in cross-country track.When I turned 17 my mom started dating a guy named Bob. At first things were fine. After about 6 months of dating, Bob moved in with us and that is when all the problems happened.I won’t go into. The hours past and finally she had to head to her ‘job’. She knew better that to be late. She left ten minutes early to ensure she arrived on time. No need to give him a reason to punish her. Mr. Michaels had given her the code to the push button entry lock for the front door via text earlier in the day and told her to let herself in when she got there. She opened the door at 6:22.She found Mr. Michaels sitting on the couch watching TV as she walked in. She started to say hi when she saw. I made another bathroom trip and changed into the teddy. I wore only the matching panties leaving my breasts unsupported. I felt them gently swaying on my chest as I walked back to the bed. My nipples got hard as they rubbed against the silky teddy top. A warm feeling developed in my tummy as my mind drifted back to the feelings of earlier this afternoon when I imagined the doctor and I together. My body demanded satisfaction and I knew that I had only a single way to satisfy my increasing. Lifting her into my truck bed I’m quickly covering the bed of my truck with a plastic tarp.My hands are shaking as I lift her skirt to her waist. I’m pulling her panties off and she’s bucking like a wild mare, trying to bite my hand.I'm pushing the silk panties into her mouth. Then I'm removing my belt and wrapping it around her mouth, firmly securing the panties.Her moans get louder when she feels my two large fingers being forced into her soaking wet pussy.She's whimpering into the panties. I.
