The Heinz's lived over the road from us. For years we'd watched their children when they had to go out and vice versa.
They had a son and daughter Kelly, with Kelly being the eldest. She was a beautiful girl, long blonde hair all the way to her delicious butt and a body, which was always distracting.
Although she was now 18, her life had been rather sheltered, resulting in her being quite, innocent, and a little naΓ―ve.
One evening, her parents had to attend a school function for her brother and as usual, just for safety sake, I went over to be with Kelly, until they came home.
I arrived, switched on the TV took up my usual position on the couch, settling in for the evening.
I'd been there an hour or so when Kelly came down from her room, propping on the floor in front of me.
She sat down, her legs were wide apart at the knees, with the lower legs crossed. It was all I could do to keep my eyes off her white panties and her crutch.
Her short summer dress had ridden up, so her gorgeous legs were fully exposed with half her butt visible.
My cock had responded accordingly, my heart beat had increased, as I lusted for her in my mind. Suddenly she blurts out, "do you think I should start to have sex yet?"
I struggled out of my erotic fantasy, my mind raced in an effort to answer her, but with my cock now ruling my brain, lust took over.
Instead of behaving in a responsible adult way, telling her to ask her parents about those things, my cock driven brain took me down the road of lust.
Wanting to know more, I asked her if she wanted sex? Or were her friends pressuring her into it? Incredibly, she stated she'd been masturbating a lot, and really wanted to have sex with someone.
My cock was now bursting as I continued the conversation, all the time, imagining myself fucking her.
I asked how many times she'd masturbated, how often, what she thought of when she did, all the time, loving what I was imagining, thrilling to the throbbing of my cock as she described her thoughts and actions, in her answers.
I then asked if she'd be comfortable being naked in front of someone. She replied she'd been told by her friends and many boys at school had commented she had a nice body, so she wasn't ashamed of it.
I thought for a minute and then suggested it was one thing to imagine these things but in reality, it may not be as easy for her.
She seemed to have given it a lot of thought, then it crossed my mind how clumsy most boys of her age were.
