Jimmy had felt a couple of girls up, in the movies and in the corridor at school, after a dance. He had squeezed tit, both outside and inside a bra, and once a naughty girl had allowed him to have a feel of her hot pussy. But that was as far as his experience extended. He had never known the joy of having a girl even touch his naked prick, let alone fucking his cock into a cunt or a mouth.

He thought about the girls at school when he jacked off.

But mostly he thought about Elizabeth Tremayne. She was a married woman! She was no doubt getting well fucked every night! Jimmy found that a far more satisfying masturbatory fantasy than thinking about virgin girls who had never so much as touched his fucker.

Today, as he cut the grass, he had seen Elizabeth as she looked out her bedroom window.

Had the youth known what Elizabeth had been thinking, he would have come in his pants, on the spot. Not knowing, he still began to get a throbbing hard-on that was in need of attention. He tried to ignore it, but his cock kept getting bigger and harder and hotter. He guessed he had better jack it off, or else he was liable to cream in his jeans. He put the lawn mower back in the tool, shed.

He was tempted to jack off in the sheet.

But then he had a better idea. Elizabeth was no longer at her bedroom window. Maybe she had gone to the bathroom – naked, of course – and he could get a look at her silhouette on the frosted glass if he sought a vantage point in the bushes that extended along the common pound behind the houses on that street. He liked to jerk off in the open air. It was more refreshing and he could let his jism fly where it would, without having to mop up afterwards, as he did in the house or the shed.
