It was so big and hard. I didn't have anything to compare it to but it seemed to be huge. So many sensations were going through my body. I took a dee...p breath and swallowed hard. Suddenly his penis twitched. It caught me completely off guard and I made an audible sound like someone had scared me. I looked away but right into my step-fathers eyes. "Hi Heather," he said softly. Shocked again, I broke eye contact, but was once again looking at his hard-on. "Is your mother gone?" he asked while. She's gotten pretty used to this and admits that it adds some excitement to what appears to others to be an otherwise conservative ordinary marriage.One afternoon I called her and suggested that she meet me at the front door at about five o'clock for a surprise. She asked what I had I mind, but I simply told her to be ready for whatever might happen. I called her about 4:00 in the afternoon. She had just finished showering and was starting to do her hair and makeup. I told her that when she met. Big-time! The movie, in a vacuum, might not have been all that stimulating, but when I had seen my own Shirley, nude and in motion, it had become enthralling. Suddenly, I was glad that she'd been in those damned movies! I wanted to collect them all! I wanted to cut everything out of all four of her movies except the scenes she was in -- preferably alone. I wanted to get an expert film-cutter to combine them all into one feature-length tribute to my amazing, gorgeous, sexy, beloved Shirley!And I. She had my dick in a grip that almost hurt, and I saw the foam working out of her, soaking his crotch.When she had come down a little. Steve rolled her over on her back, and started fucking her, slow and steady at first, and then faster and harder. This time he was fucking for himself. She cried out every time he plowed into her."Get in there close, Bill," he said, spreading his legs more, slowing his tempo, "play with my balls."They were more than a handful, swollen and hard, tight up against.
