A few minutes later, Delilah stood in the stable waiting for Taylor and Jason to return. She couldn’t believe things had gone so well and deep down she fully expected some kind of trick when the two humans came back.
The horse was surprised when Jason and Delilah returned, both in their robes. Jason seemed bewildered by everything that had just transpired back in the ranch house and Delilah, for her part, was equally shocked. Man and horse stared at each other and each flashed a knowing grin.
“Well, hello again, my friend,” Delilah winked at Jason, prompting Taylor to chuckle.
“So... I’ve explained to hubby about our little arrangement,” Taylor whispered. “As long as we can all stay open and honest about it, I think we’re going to be okay. You two can keep changing and experimenting, and... maybe me too. We’ll see what happens. But first, it’s three in the morning and we all need sleep.”
“I agree,” Delilah nodded, relieved with the final outcome.
With a fond embrace and relief, Jason and Delilah said good night. The mare was left to do as she pleased in the stable, with her stall and the main door unlocked, and they’d figure out everything else in the morning.
A few minutes later, Taylor snuck back into the stable, catching Delilah off guard. The human woman approached meekly, a little shy, and both the horse and woman shared a sly smile.
“Delilah, sweetheart...” Taylor whispered, wrapping her arms around the horse’s neck. “You’re family now, and if you need anything at all, please come up to the house and see us. I’ll be happy to help you with your every need.”
“M-My every need?” Delilah said pointedly.
“Your. Every. Need.” Taylor repeated, ensuring the horse knew exactly what she meant.
“Thank you, ma’am,” Delilah whispered back breathlessly. “I can’t wait to see where this goes for all of us.”
The human winked and stroked the horse’s mane before giving her a snuggle and heading back inside.
Delilah’s heart was racing now. This could go so many ways! All of them potentially full of delights.

Back in the bedroom of the ranch house, Taylor was turned on. It wasn’t just Jason, either... it was Delilah, her lustful animal nature, her polite gentility. The changes. The potential of exploration.
“The idea of this... the idea of sex changing a person. Of you growing a big horse cock... it’s intoxicating,” Taylor admitted. “I want to see it.”
“O-Okay...” Jason whispered. “But... I thought we wanted to stay in control?”
“We know your fluids are infected, love,” Taylor whispered gently, smiling as her hands stroked her husband’s chest. “if we’re careful, we can avoid any unwanted transformations. Although I wonder, will Delilah change more if she gets your cum and just your cum? Will you change more if you get her juices?”
Jason blushed deep red and gulped. “I... I don’t know.”
“Take off that robe, baby. Let me see my sexy horse-cocked husband.”
Jason removed his robe as instructed and crouched on the bed with his sheath twitching and his large black balls hanging softly against his thigh.
“Jerk it for me. Get it big.”
Jason nodded, easily aroused enough to spring to erection. Under Taylor’s lustful gaze, Jason built up his cock to full size. All fourteen inches jutted proudly from his groin, the dappled pink and black accenting the ridges and girth of his horse-shaped member. As he began to flare, gently masturbating, Taylor gasped.
“My god... you bell too. Just like a real horse.”
“Mmmhmmm...” Jason smiled with pride, glancing down at his member and feeling a flush of pride at Taylor’s reaction.
“Keep teasing it honey, let’s see how big you can get.”
The man complied, picturing Delilah’s aroused horse pussy. That made him quite stiff. He pictured Taylor changing. He pictured himself getting even bigger. He began to take in steady even breaths as he teased himself to full, both humans marvelling as Jason’s cock only seemed to grow bigger and bigger, the flare increasing to a massive size, the shaft swelling down to his medial ring. By the time he was fully grown the urge was massive and he was panting and blushing.
“You need relief...” Taylor whispered, watching her husband’s balls churn. “This is incredible. You were always a horny guy... now you’re part animal.”
Jason whimpered, his cock starting to leak pre from the flared downward opening.
“Hold it in, big fella. I’ll be right back.”
Jason nodded, keeping himself big and hard, stroking enough to keep his frustration up but not enough to cum. It was difficult to fight the urge not to finish himself, but he knew what Taylor was thinking and he grinned. He hoped he was right.
As he expected, the woman came upstairs with a small canning small and a pair of rubber gloves. Jason’s heart jumped in excitement. He was right! What a clever woman!
“Here, baby...” Taylor whispered, putting on the gloves and gripping the man’s hot throbbing horse dick. She angled his shaft toward the jar, marvelling at the firmness and tension of his engorged member, the veins thick and tight, and pointed the edge of the mushroom toward the opening. “Finish it off for me, okay?”
Jason happily complied, tugging himself with both hands as he great hot and sweaty. The scent of his horse dick was undeniably musky and animal, which reached Taylor’s senses and made her blush. The woman watched as he gave a final big swell, his cock close to bursting in size, and with a gasp, Jason released, squirting his load with such force it hit the bottom of the jar and splattered upward.
Taylor watched in awe. Squirt after squirt until he was empty, the last few drops dripping into the quarter filled jar as Jason squeezed them out.
“Honey...” Taylor gaped. “What a load!”
“Y-Yeah...” Jason said sleepily, eyes growing heavy.
The woman put the twist lid on the jar, sealing in the contaminated contents, and cleaned up the mess as Jason fell to the bed panting, his cock lazily deflating and pulling back into his sheath. She wiped her husband’s groin down with a sanitized cloth, made sure nothing had split on the bed, and ensured the outside of the jar was safe to handle.
She went downstairs, putting the cooling cum in the fridge, and went back to lie next to Jason. He fell asleep quickly, sated and happy with everything, but Taylor couldn’t sleep.
She waited until Jason’s telltale little snores began, and climbed out of bed. By this time, the cum in the fridge had cooled. She picked up the jar from the fridge, eyes wide, and pure wonder took her expression.
What would happen if she gave some to Delilah? Or... to herself? What if she drank a little? What if Delilah drank a little? What if she got the turkey injector from the drawer and put it inside herself? What if she did the same to Delilah? What if she gave some to the big stallion in the stable across from Delilah? Or... what if she just put it back in the fridge and waited?
