She pumped her gently rounded belly out toward the beast and he brayed, spraying slobber.

Maria, athletic and acrobatic, began to bend over backwards. With incredible agility, the buxom beauty bowed back, her body taut. Sinews rippled in her firm thighs as her weight shifted from the vertical. Her head and shoulders dropped back and her heavy tits loomed upward, thrusting. She dipped farther and her hair hung down, sweeping against the floor of the platform.

She was so lithe, and limber that it seemed as if, had she been bending forwards instead of backwards, she could have gone down on herself – which, in fact, she could, and often did, as a sort of curtain call following the donkey-fuck.

Gracefully, she sank down until her head and shoulders were braced on the platform. Her feet were planted flat and her lush body was bent like a taut bow, arched up so that her loins were level with the burro's prick. Her exposed cunt was bubbling with fuck-juices. Trickles slid down, seeping into the crack of her ass.

The burro stopped looking for that other mysterious source of female fragrance, now that he was presented with Maria's inviting cunt in this position that the dumb brute had come to know so well.

The animal shuffled forward, awkwardly, stepping around his looming cock-shaft as if he were striding over the top rail of a fence. His balls, so recently drained, were already ballooning at the root of his cock. His head ducked down for a nuzzle in Maria's groin, then flew up and the beast advanced, covering her arched form. His head hovered over her tits and his prick loomed into her crotch.

His cock-muscles worked, causing the naked slab of his cock-head to flare in Maria's cunt slot. She moaned, shifting her ass from side to side, rubbing her foamy cunt against his bloated cock-slab. The animal shoved, but his cock-head slipped up and out, running over her cunt-mound. His piss-hole had begun to dribble again.
