It was always when we were alone like late at night, or when our parents were out. She -(TM)d have me pretend I was a captured spy and she was the interrogator. She would say she needed to search me and then proceed to slowly strip me one piece of clothing at a time. Once in my underwear only she -(TM)d tie my hands behind my back and then order me to hand over the -secret tapes - or she would have to torture me. I of course always refused to cooperate knowing what would come next. She -(TM)d say, -Well I -(TM)ll just have to search for them myself then. Maybe you have them in here -, reaching down into my underwear feeling my dick and balls moving her hand around and pulling on my shaft now and again. She -(TM)d reach under my balls and squeeze my ass too. She would just generally grope me till I was hard as a rock. She seemed fascinated with my dick. Once erect she -(TM)d pull my underwear down and off and tie me with my shaft waving around in the air to a big chair we had in the den with my legs spread apart. She -(TM)d then usually gag me. She -(TM)d tie me down so well I could not get lose even if I really wanted too (not that I really wanted too anyway!). I -(TM)d -mmmphfff - through my gag and struggle playing the part but she'd always get her way of course. She -(TM)d tickle and slap my rock hard shaft, yank on it, stroke it and touch it till I was near orgasm. She always would stop right before and not let me come! She -(TM)d do it for what felt like hours sometimes. She -(TM)d keep me that way slowly stroking me telling me I had to confess or else. Finally after making me beg for it, flexing in my chair, she would finally let me come shooting my load like a gusher through the air, and sometimes all over me if she felt like it and pointed it back at me. One time she took out a buzzing silver egg looking thing that had a cord (later I found out it was a vibrator!) and held it on my anus while stroking me with baby oil till I came with a gut wrenching orgasm. We called the game Persuasion. It was so bad of us but yet still remains some of my most memorable sexual memories.
