The lack of more changes really disappointed him. He had been so excited by all this, he had hoped that it would be a complete change. His balls and sheathe were still pink even. With nothing further happening, he was too tired to get off the horse to fuck it, but he was still horny, so he started to stroke himself, admiring the feel of his new dick and the medial ring and the bumps and grooves at the top. The horse kept on walking as he pumped himself and got closer to orgasm. He leaned back in the saddle and closed his eyes as he thoroughly enjoyed the masturbation session.
"Ohhh" cried Jason as he came with his horse cock for the first time. The spray of cum went straight and his such landed around the saddle and his legs, with some getting on his shirt. Tired from all the orgasm he had had that day, and the vernal day itself, he slumped forward in the saddle, satisfied but spent, and waited for the horse to finish taking them home.
When he got there, it was nearly 8 PM. The first thing he did was take care of the horse that he had ridden that day. "Thanks for the rides" he said while winking at the horse. Patting his now heftier crotch, he made his way from the barn to the house. He found a pair of work overalls in the barn and put those over himself, not sure how to explain that his crotch to his wife yet. His wife Taylor was home, but he didn't say much to her as he passed her in the living room on his way to tenbedroom. "Long day out there" He grunted as he walked past her.
"I'll say" she responded. "You've been gone all day! You were only supposed to be gone a couple hours." She wrinkled her nose as he passed closest to her. "And you smell like, really badly of horse, even for someone who's been on a horse all day. Almost like you are a horse."
He shrugged his shoulders at the smell part. "I took some paths I didn't expect, wound up a little lost but pretty happy with the ride overall." He chuckled at that last part, almost like it was an inside joke that only he was privy to. She raised an eyebrow at that but let it slide.
"Well, I'm off to bed" he said.
"Are you sure? I thought we could do stuff tonight..."
"No thanks, this day has really worn me out" he said and went off to the bedroom to sleep. It didn't take him long after he stripped out of his clothes and got under the covers. Before getting into bed, he admired his body in the full length mirror in the room. Nothing had changed besides his crotch, and that had remained the same since his last change. Disappointed but still mostly happy, he turned off the lights and hit the hay.
Taylor was still awake in the living room. She was frustrated he had been gone so long and was so tired he couldn't stay up to do anything, sexual or otherwise. It wasn't that easy to find the time in their busy lives to do stuff like cuddle and kiss and have sex so she had really been looking forward to tonight. She waited out there a while watching tv and playing on her phone until she too got tired and headed for bed. She walked into the dark room quietly, watching Jason sleep with his arms splayed out and his mouth wide open. She crawled in beside him and rested her face on his bare chest, with one arm over him. She closed her eyes and was asleep soon too.
