Juanita rushed forward to assist, knowing that, cavernous as Maria's cunt-hole was, the burro's cock was too huge to slip in without guidance.

The slender, nubile young girl knelt down beside the upthrust loins of the voluptuous woman. The donkey waited patiently, his cock pulsing as it jutted up out of Maria's groin like a bludgeon poised to strike her.

Juanita threw her arm around his cock-stalk, hooking her elbow and gripping his cock, just behind his cock-head, in the crook of her arm. With her other hand, she spread the lips of Maria's elastic cunt open wider. Then she levered the animal's cock down, forcing his cock-knob into Maria's fuck-slot.

The burro whimpered and his cock-head pulsed. Gooey cum oozed out, running into the woman's cunt, all milky and foamy in her coral pink cunt-folds.

He humped urgently.

Maria squirmed, pushing her cunt down eagerly to meet the beast's fuck-thrust.

Juanita released the animal's cock-stalk now that his cock-knob was in place. Using both hands, she spread Maria's cunt open even farther and then began to drag the woman's pliable cunt-lips down over the donkey's cock-head.

Inch by inch, his enormous wedge of cock-meat edged into her cunt, his dusky cock-knob nudging into her rosy pink cunt-folds. Maria's pussy sucked on him, her cunt-lips dragging him deeper. Her ass swung, her hips jolted. The burro fucked remorselessly, but with a controlled effort, knowing that too frantic an assault would defeat his purpose.

With a slurp, his cock-head vanished.

Juanita had done her part, helping them begin the coupling, and she drew her hands away now.
