I hesitated, looking down at her tight, sexy ass and felt the heat rising in me again! the bikini bottom at the back was just a thin rope like strap a...ross the middle and an equally thin rope strap that fitted neatly into the crack of her ass, so effectively at the back at least she was naked! I must have hesitated too long, as she lifted slightly and turned to look at me and smiled, "Please, daddy, your hands are making me feel so special!", I could never resist that smile, and I started to. The day after we left grandma's place, my mom was determined to get through. I don't know if it was circumstances, or she needed and excuse to do it, but she immediately went to John to take him up on his offer. My mom told him she would do what he wanted, but she needed a big pay raise, extra hours, amongst other things. John agreed, but told her she knew what he wanted. My mom knew what he wanted and was willing to give it to him. John took my mom into his office, and told her to get. ‘Are you ready for me to be inside you?’ She looked up at me. ‘Yes. Pleas put your cock inside me,’ she said. I stood up and pulled my pants down. Because of the heat, I didn’t wear any underwear, so my 7′ dick was pointing straight at her. I don’t think she had gotten laid in a while because she looked at my dick like it was the biggest one in the world! I eased myself down in between her legs. I may not be long down there, but I am thick, especially in the head. I slowly pushed my head inside. I blushed and told him me and a boy did years ago. Really, did you like it he asked. A little, I told him. He reached around and grabbed my dick. Again I jumped,slapping his hand. Relax, it's just us here. After thinking about it I moved my hands. He took the soap and latherred up his hand and started stroking my dick. I got hard quickly, he stroked me slow at first then faster. I started breathing faster and my heart pounded. He pressed against me from behind and I felt his hard dick pushing.
