Taking Amy’s little sister Tina

Like I have told earlier Janet , Amy and Tina’s mother, had the girls at a really young age. She got pregnant with Amy when she was 13 and had her before her 14th birthday. Then against her parents, she got back with the same boy who was 18 and got pregnant again. She had Tina by her 15th birthday. Of course, as soon as the boy found out she was pregnant again, he disappeared just like he did before. So her parents picked up and moved to the same town where I lived and Janet finished school and was rasing her daughters with her parents help. Now too get back to the story of Tina.
Even though Tina was younger she had a little fuller body than Amy. What I mean is more shapely. She had larger titis and rounder butt. Amy was slimmer built. No complaints though.. I just couldnt get over the way Tina would do her sister. If Amy went to the bathroom, Tina would be all over me trying to get me to do something. She even took my hand and put it on her tits, or she would get my hand and rub it between her legs. I’m sure you have guessed I didnt resist much. There were times she would wear a dress and when Amy would have her back to us she would open her legs and show herself too me. When Tina did these things and finally left Amy and I alone. Amy paid the price. Not that she minded that much.
Janet had been getting a little worried about the fact that both girls were hanging around me so much. She even approached me one time and ask me if any thing was going on that she should know about. I just acted dumb and ask her what she was talking about and she dropped the subject pretty quick.
One Saturday I was working on the yards of the rental property that was close to our house, (that was one of my jobs in the summer) Tina came out of their house and brought me a glass of lemonade, so I stopped and talked to her for a minute. I ask her where Amy was and she said her mother and Amy had gone to town to get groceries and get Amy some new clothes and she didnt want to go with them. I drank the lemonade and told her thank you and started to get back to work when she ask me why didnt I come in and cool off a little. It was really hot so I told her ok. I really didnt have anything else in mind. At least I dont think I did. Maybe way back in the back of my mind.
Anyway I went into the house and Tina handed me a cool wet wash cloth and it did feel good and I wiped the sweat off my body.
