We said it was good and planned to meet again.That night I told Sir and he was kinda cross but found it very horny at the same time, he loves it when ... am so slutty. He Said I would be punished and set a time and date. The day come I was nervous and dressed as he told me to be in Black Stockings and my collar. He came into the room looking serious I looked at the floor. He strapped on my leather cuffs to my ankles and wrists and padlocked them on, he the got some strong fine chain and padlocked. I would see her glance down at my tits or my skirt, it was a huge turn on. Truthfully, this wasn’t helping me relax at all. I was nervous in wondering what she was thinking. But once again, if she didn’t like it, she wouldn’t be here. She put a hand on my thigh and pushed herself up off the couch, turned towards me and asked if I needed another beer. I said sure and handed her my bottle.This time it was my turn to watch her walk into the kitchen. I loved the way girl’s jeans made their ass look. I pressed the door closer and as it was going down I could hear voices coming from our pool area. I opened the back door of the garage to see who was talking. There next to the shallow end of the pool was three guys. They looked to be late twenties. I walked out to see who they where. As soon as one of them saw me he called my name. I walked up to him and said do I know you? He said probably not , as he held out his hand to shake he said but we know you. The other two came over with their hands. I walked in, threw my bag into the living room and shouted asking So what did you do all day? wondering what lie she would throw at me. She replied quickly Nothing, you know, just stayed home and watched television.. I ran to my room, and just sat on my bed. I always had the hots for my sister, although she was only 12, she had pretty nice tits, long black hair, brown eyes, and a really tight ass. She definitely was not exactly hot, but the idea of getting a blowjob from my own sister just.
