To be honest I had feelings to fuck my sister from a very long time because I used to watch a lot of incest porn featuring brother and sister, read a ...ot of incest stories here on ISS, etc. I and my sister share the same room though different beds while my mom has a different room downstairs. We have a good relationship with each other, sharing secrets talking most of the time, never fighting, etc. One night when we were sleeping, I woke up to check out my sister. There she was sleeping in her. I was so intrigued I asked her why she chose it. She explained that in that era, they were very repressed and sexual relations were never mentioned. She made us laugh by adding the fact that they had loads of c***dren so they must have been doing something right. She went on to say that the book was interesting in that it was written by a woman who through fiction takes the reader on a ride to show how older single ladies who were considered to old maids and sexually repressed but they flirted. I had to admit, I was quite proud of myself. “Oh jeez, Hallie,” Emily sighed happily, “He's really big...” Then she pushed backwards with her hips, pulling my full length into her hot, tight pussy, “Oh woww.” I had never felt anything like Emily. She was so tight my cock could barely move inside her at first, and I thought she had been hot to the touch on my fingers... this was almost like she was on fire! I forced my cock in to the hilt and held it there for a few moments, simply filling her. I looked down at myself and noted the t-shirt tapering from my huge breasts into my tightly belted jeans. I stood up, and sat straight back down again. My body just wasn't responding the way it should have been. I tried again, and found that tiptoe was the only way I could stand, and that my buttocks, back and stomach were all being strained. I sat back down and took off the trainers and jeans and pulled on the boots. This time, with the five inch heels, I could stand straight, but the position.
