My son sat with her and her son sat alongside me, and slipped his hand into mine, and as she repeated the offer to both our c***dren, he squeezed my h...nd and turned to me, 'You have to come', he pleaded and I said, 'Yes', to which she replied, 'Good, we shall go in the morning for the weekend, but tonight, you will sleep over in the flat.Everything seemed strange, as we cozied up to each other, I watched as my son sensed he was going to have sex with this beautiful sophisticated woman I had. She moaned while he assaulted her nipples with his fingers. He felt her pussy getting wet and began swatting at her chest.“Oh, David. Mommy has been so bad. I think you better spank me.”“Susan, you are a bad girl. Lay on my lap and suck my cock. Do it whore!”Susan lay on David’s lap and licked his cock while he swatted her several times on her buttocks. She loved getting spanked, and David got excited while he spanked her, and she pleasured him with her mouth.David pushed his fingers into. "Is this all the selection you have right now?" I asked."No come around to the door and I will show you what I have back here." he said as he walked to the door to unlock it for me to enter.As I entered the back of the display counter Phil showed me to the cooler at the opposite end of the back room.As I entered the cooler I heard him close and slide the bolt on the door to lock us in.I felt a little nervous but thought about how I asked for this by teasing him.My nipples were hard like little. I started to have this type of small chat with her regarding girls after few days I got the opportunity and that was the day of first fuck for me and my parents had went to attend a function for two days to Mumbai and my brother had to go on business trip as my dad was out at that eveI asked her to cook food that she liked so that we can have dinner of her liking and while she was cooking I had talked to her after that we had dinner at around 8 pm and after that we sat on the sofa to watch.
