I am a doctor by profession. I am 24 yrs old. I am an avid reader of ISS stories, which by the way is the reason for posting my real life sex story he...e. This incident took place when I was doing my internship in a hospital in Bangalore. I was posted in Dermatology. Though I was least interested in this posting, what kept me going was this hottie, Dr. Kiran Kaur 27 yrs old, fair skinned Punjabi, who was doing her post graduation in Dermat. She was married to an engineer, who was working in. She spent a little extra time at the top of the corona, a spot she knew was erotically, very sensitive to him.All three were in ecstasy, living in the moment and forgetting any issues caused by time. They felt like they were in their late twenties in body and in their fifties in wisdom, a great combination, but then again, their having been together for almost thirty years helped them to know how to please each other.After another 15 minutes, Sarah shifted, letting Greg's cock fall from her. Tommy said, “Jen, this is my mom Laura.”She got up and shook my hand, but she also gave me a hug.“And this is my older half-sister, Amy.”She came over to me, and gave me a big hug too. She pulled back and we looked at each other. She said; “We are identical except that my hair is shorter.”Dad got up and said, “Jennifer please have a seat.”I sat down and asked, “What’s going on Dad?”“There are things I need to tell you: first your mom did leave us to have more sex; she was, or I should say she. He knew that she had a crush on him since she was a pre-teen but he always thought that she was too young for him. It was the joke in his family that Amy was going to be his girlfriend. At first it got under his skin when his parents started kidding him about Amy. After she reached her teens she seemed to be always there but not as infatuated with him as she was when she was younger.After Duke was in high school and started dating, Amy would critique his dates. There was never a decent woman.
