Always had a good relationship with my younger sister. She is two years younger than me. We were about 5 & 3 on a rainy day under our front porch when a neighbor kid older than us had his dick out, he told us to take turns holding it and massaging it. A few years later another older boy & myself had my sister take off her pants so we could inspect her young pussy. She enjoyed the attention and held our dicks & rubbed them. I was 15 & she was 13, our parents were away in Northern WI for a week. I was in charge and when night came we started to wrestle. In playing around I felt her young budding tits and put my hand down her pants. She did not protest and I grew bolder, rubbing her pussy that was just sprouting hair. I'd insert a finger or two and just kept feeling rubbing & exploring her c**t. she seemed to enjoy the attention. This continued for several nights. We took a Greyhound bus up North on an overnight trip to join our parents. the bus left Chicago at 10:30 PM.
We snuggled under a blanket & spooned. When I felt she was dozing off I slowly put my hands down her pants until I reached her young pussy. She knew what I was doing as she slightly lifted her leg to allow me full access to rub her pussy & insert my middle finger into her. We rode through the night that way as I could not sleep and rubbed her pussy & finger fucked her for a long time. When we were in high school we were at a New Years Eve party and she kissed me at Midnight & shoved her tongue in my mouth. I did get to see her nice tits when I came home one night. It was a very hot night, I was drunk, she was sleeping on her bed in just a pair of panties, no covers & no top. I turned on the light and was amazed at the sight, of her tits that were huge as she laid sleeping on her back. I tried to feel her up and lick her pussy, but she did not want to. She grew into a full bodied woman with large breasts and a nice body. We never went any further and we are 63 & 61 today. I still look at her around the swimming pool in he bathing suit & envision her c**t & tits. Maybe someday we will fuck, who knows?
