Then she looked down and saw that Buck was getting a hard on. Bonny tilted sideways on his back, gazing under him, fascinated. His prick was long and thick and getting longer and thicker by the moment, the huge cock extending in a series of jolts, and rising up to the horizontal. His naked black cockhead came sliding out from its leathery sheath, a massive slab of smoking hot cockmeat.

"Holy shit!" Bonny gasped.

She leaned closer, one knee hooked over his back, staring in awe at his gigantic cock. She shook her head as if in disbelief. Buck snorted and tossed his head about wildly. Slowly, the dreamy smile on Bonny's sensual lips changed to a wicked grin.

She leaned right out over the pony's flank, like an Indian shielding himself from a wagon train's guns, one thigh hooked across his back and the other leg sliding under him. She rubbed her instep and ankle slowly up and down the animal's cocksaft. The fat prick throbbed against her foot and Bonny whimpered. She fluttered her toes against the flaring wedge of his naked black cockhead and watched the huge prick pump in and out like an inhaling lung.

Bonny was wondering: Should she jerk the pony off?

She sort of owed him a favor. After all, she'd creamed on his back and by doing so, had caused that huge hard on, so she was sort of responsible for dealing with it. Then, too, she reasoned, it would be too embarrassing to bring the pony home in that aroused condition, and how could she make his cock soft again, unless she emptied his balls? These were justifiable reasons, certainly, but they weren't really the main reason – which was that naughty Bonny wanted to jerk the pony off! Her hands were itching for a feel of that hard, hot prickmeat and she was longing to have it throbbing in her grip, and then to see all that hot, thick horse cum spurt out of his pisshole. It was kind of naughty, she figured, but it was all the more exciting because of that. And it wasn't really wicked, not as if she was fucking him or sucking him off, she reasoned. She would never do that, would she?
