The trail was long and winding as you and Jessica made your way towards the lake. As you looked around the forested area, it was running pretty long and as you made your way through it mixed with some side trails it felt like you were going backwards more than anything else. At this point you felt pretty lost and found yourselves in an out of the way clearing with a bench and a place to feed the horses.
"Well, this seems nice, why don't we stop here for a little while?" Jessica suggested as you climbed off your horses. She smiled as she took a seat on the bench as the horses started to graze.
You were a little surprised that they weren't eating the horse feed and oats that had been set out for them by the Zoo people. Your eyes fell on your girlfriend as she leaned back, she looked taller than you remembered and you felt an itching feeling on your body as you scratched at it a little not really paying attention as your fingers started to feel a little stiff.
"What are you doing?" You asked in shock as you looked over at Jessica who was starting to eat the feed. "That's for the horses."
"Yeah, but it smelled so good I couldn't resist," she said and gave you a smile as she swished her tail a little. "Come on try it, it tastes good and its not like the horses are eating it anyway. Come on, try some."
You looked at her strangely for a moment but as you moved over there you noticed that it did indeed smell good. You tried to pick it up in your hand, but your fingers stiffened and you lowered them as you craned your neck down and started eating. You couldn't believe how good it tasted as you kept eating, you didn't even notice as you fell down onto all fours and you stepped back as fur was growing over your body without you even noticing.
As you looked at Jessica, she was already nearly transformed into a horse with her clothes having torn into shreds, all that reminded her that she was once human was her face that was still forming into a horse muzzle. You smiled a little as she swished her tail, her vagina winked at you as you smelled her heat as your cock slid out of its sheath.
You could smell another scent of heat coming from another mare nearby. Your arousal was growing as you decided what to do.
