Mum had been a single mum most of our lives. She was just 16 with twin c***dren & all alone. I remember as a young boy mum often joining us in the bat..., we would all play with toys, laugh & sing & play with soap, blowing bubbles & generally enjoying each others company. I clearly remember the last bath mum had with us. Mum would have still only been 27 or 28. She loved exercise & always looked fit, young and healthy, something she instilled in both my sister & I. I know I had started noticing. By the time I was also ready and started to kiss her. I then started fondling her breasts over her nighty. She then took me to her bedroom and started to remove her nighty. She was now only in her panties as she was wearing no bra inside. She removed her panties too and lied down on the bed and stared to finger her pussy and fondling her breasts. Wow she was looking like an angel in her birthday suit with those beautiful breasts and clean shaved pussy. She was so hot that she seemed to have. Susan answered it and all Martin could hear was she told someone that she would meet them in an hour. Martin thought it was good luck, as he wouldn't have to go out when Susan said "You'll have to change, we're meeting Bill and his partner Ron for dinner at the Iron Skillet Supper Club. In your closet you'll find a black evening dress that will be perfect for this evening, now go get it on then come into my bedroom and help me get ready." Martin went into the guestroom and looked in the closet. He gently straddled her with his legs either side, being careful not to emit his full weight on to her, he could feel his penis rub against her pussy and it felt wonderful. He kissed her gently on the mouth before giving her a more intense kiss, allowing his tongue to freely wonder into her mouth and intertwine with her waiting tongue. Her mouth tasted great, sweet and somehow intimate. Not as delicious as her sweet pussy of course, but still yummy. He started to slowly massage her boobs,.
