Since I was as regular as clockwork, we had sex at least once a day, four days before and six days after the appointed day every month.One thing we di...n’t change much was our somewhat kinky sex life. He still would tie me to the bed and use the Hitachi vibrator to tease several orgasms out of me as I jerked and pulled at my tethers, or do me doggie and spank my ass ‘til it burned in pleasure, all before plunging his eight inches into me—always driving me to even more climaxes before depositing. That's when some of his other college friends drove up and he took off with them laughing how I as the only 'kid' left in the house still got grounded. I was supposed to go out with my friends tonight and play with the new miniatures in our favorite war game, but Jerkface decided to steal one while I was painting them and went and broke it. I'd be able to glue it together, but even though I was home alone today, there would be no way I'd get home in time before my mom. If I went out after. We headed out to his car and drove to KFC. It was normal conversation in the car. Flirting of course. I couldn't stop laughing. He was so cute and funny and every now and then he would turn to me and smile. We got to KFC, and we ordered a bargain bucket and sat on a table in the corner and ate. The flirting carried on and so did the laughing. We hardly broke eye contact the whole time. It was amazing! His bright green eyes fixed on me. After an hour, we broke eye contact and he looked at his. Then she stopped again. She seemed to be trying hard not to wake me. This was just weird enough for me to let it go and see what she was up to. She reached the edge of my bed and ever so slowly sat down on it. At this point I could see that it was my big sister Jill. She was watching my face intently but she obviously couldn’t tell in the dark that I had one eye open just a tiny bit. I could barely make out that she was wearing nothing but a nightshirt and panties. What the heck was she up to?.
