Tommy and Debby had dressed in hooded jackets that pretty well disguised them. They arrived early, taking seats at the front of the wagon where they didn't think Rebecca would notice them. Debby had been excited about playing the spy, and, truth is told, was rather hoping that they would catch Rebecca being naughty so that there would be a scandal. Tommy, of course, was hoping Rebecca would prove faithful and innocent, but he, too, found the idea of spying on her rather exciting.

Rebecca and Harry had arrived at the last minute, arm in arm, and laughing merrily, causing Tommy to frown. They had taken seats halfway along the big wagon, sitting snuggled up close. So far, they had not done any necking or petting. They were only talking, as far as Tommy could see. He was keeping his eyes on them from the shadows of his hood, as the four-horse team hauled them up the trail.

Soon enough, most of the courting couples were kissing and caressing each other under their blankets, and Tommy, began to see a grave disadvantage in being with his sister. Debby really had become a delectable little minx, he thought. She had curly, blonde hair and big, blue eyes and a sensual mouth with a full, lower lip. Her tits were firm and bouncy, she had shapely legs, and her ass was like an inverted valentine. Tommy knew she had a lot of dates, and he speculated on whether she did naughty things.

It excited him to think so!

He had his arm around her shoulders, pretending that they were a dating couple, and, as the wagon rocked, his hand slipped down, as if by accident, onto the slope of her tit. Debby didn't seem to notice, and Tommy left it there, not caressing her, of course, but letting the motion of the wagon move his palm on her tit.
