Harry is, thankfully, somewhat restrained.
Watching Vicky dart after Jessica on foot, leaving Harry behind you were certain he would mount and claim you...but...he hadn't? This was puzzling. As you thought about it, though 'think' could barely be used to describe your brain's capability with the incessant, curious tongue of that beautiful black rogue's tongue exploring your soon to be permanent female anatomy; as you thought (perhaps schemed?) you became less puzzled and more alarmed.
You looked back at Harry. He wasn't even attempting to mate, just keeping you juicing and stewing in your heat. Before running off Vicky had whispered into his ear.
Did she really have that power, even after turning a human into a horse? The stallions had always, well since you'd become a mare they had seemed sort of all powerful; the stallions. Yet here was Harry seemingly able to control his truly animal urges. Was it you? Were you somehow lacking?
A shudder of fear ran through you; no longer at Vicky's possible powers but at the possibility that you might be inadequate as a mare. But Harry had wanted you once? What could have changed? How could he resist now? It was the same woods he had taken you in that first day...oh...oh, he had already had you.
That must be it. Harry had been inside you and so now he wasn't as excited or afraid you'd 'escape' him.
...unless it was...what if he had been displeased with your coupling skills?
You sprayed a stream of urine in enticement.
Harry snuffed at it as you spread your hind legs and lifted your tail; but he wasn't responding any more urgently than before you sprayed.
You heard voices as you turned and lowered your head underneath Harry. It was Vicky, you recognized her voice...and the other was familiar too. Female, but who was it? Your tongue reached out to Harry's organ; you couldn't believe you were actually doing this though Harry didn't seem surprised as he teasingly moved away. His move away from your tongue forced you to strain your neck, tongue out, as you walked to him again.
You heard clapping - Vicky, you knew without even looking.
"You're such a slut Princess!" giggled the other voice, urging you on with it's tone.
Now you recognized the voice, it was Jessica! You were about to turn but Harry decided it was time for you to service him orally and stepped his hardened prick onto your outstretched tongue.
Mmmmmm....it was divine! His taste in your mouth affirmed your self confidence. Of course you had satisfied him that first time in these woods! He still desired you, how silly to have doubted your abilities as a mare in season.
You saw Harry's head swing to look over at Vicky and Jessica.
"I'm not sure buddy," Vicky chuckled, "she might not be ready for a brute like you..."
You redoubled your effort on his drippy cock, some hint of mare taste still lingered on it...but no wonder! Harry was the epitome of virility. Your eyes wandered over him even as your tongue sought to gratify his equine penis...but thoughts started to seep in.
What were you doing? Jessica was fine, you didn't have to sacrifice yourself any more. Jessica was fine...wait, what was Jessica doing? She was more than fine...she was holding hands with Vicky, nibbling at her ear...naked.
"Don't be mean! Of course she's ready...my Goodness! Look at her! She's seeping lubricant, it's pooling on the ground." then to Harry Jessica nodded her head and gave the permission he had been waiting for, "Take her stud; she was made for this!" and laughed as Harry began his ascent up unto your back.
