Go for a swim

You glance around, then strip off your dress and hang it in a tree. Naked, you step down into the pool, shivering as the icy water slides up your legs. You balls draw up and your cock shrinks back into your sheath as you walk deeper, your breath coming in short gasps. It's certainly cold, but it feels refreshing on your fevered hide. You dip your breasts into the water, your nipples peaking, as hard as rocks. You swim across the pool and take a seat on a partially submerged boulder, your back arched and your tits jutting out as you pull your long hair back at the nape of your neck, the breeze raising goosebumps on your wet hide. It feels sublime, but it does little to ease the aching need in your womb.

Suddenly, the boulder shrugs, throwing you back into the water. You splash and sputter, pushing your hair back out of your eyes as you watch the boulder uncoil, the long, scaled head of a water serpent rising above the surface, silver eyes like mirrors reflecting your shocked face back at you.

"What have we here?" the serpent asks, its thin, forked tongue darting out to taste the air. "A striped ass? I haven't eaten ass in forever."

"I-I'm not an ass," you say, your voice trembling. "I'm a Zebra, and you don't want to eat me."

"Why not?" the serpent asks, slithering toward you, its long, muscular body at least twenty feet in length and thicker than your thigh. "What use are you, if not to eat?"

You back slowly toward the edge of the pool, your hooves slipping on the loose rocks that cover the bottom. The water is only waist deep. You could make a run for it.
