He heaved up again, groaning. Rebecca grinned, amused by his frantic urgency, and thrilled by it, as well. She was considering teasing him a bit longer. But she certainly didn't want to run the risk of bringing him off too soon.

Fuck-juice was wasted on denim.

She grasped the clasp of his zipper and began to draw it down, lowly, lowering it an inch and pausing, then pulling down another inch. She unsnapped the waistband of his jeans and unbuckled his belt, then pulled the zipper down the rest of the way.

Harry's fly gaped open in a wide vee. Knowing Rebecca as he did, and foreseeing the possibility of getting at least a hand-job on the hayride, Harry had taken the precaution of not wearing any underwear. As his fly few open, his prick jerked out, naked.

Tommy moaned as he looked down the wagon and saw what was happening. Kissing and getting felt up had been bad enough, but now his girlfriend had gone too far! Yet, despite the torment of his jealousy, Tommy found that he was fascinated. He hated to see his girlfriend misbehaving, yet, at the same time, wanted very much to watch.

"Oh, golly, she's gonna jerk him off!" Debby whispered.

She, too, was intrigued by the sight. Unlike her brother, she didn't have the stimulation of jealousy to enhance her interest, but the sight of Harry's massive cock was really turning her on.

Harry's long, thick cock towered over his loins, a fat, dark vein pulsing up the underside. His cock-head was flaring out, so hot it seemed to be glowing an angry red. His piss-hole gaped open, and the tip of his cock was frothy with his cum.

Rebecca reached into his open fly and hauled out his swollen prick, exposing all of his sex tackle to her adoring gaze – and to the gaze of the sibling observers.

Rebecca leaned over his groin. Her eyes crossed as she looked upon his cock-head. She was panting heavily, and her breath steamed in the chilly air. The head of Harry's prick was steaming, too, as cum evaporated from his fiery meat.
