Sasha and Jacob started to run through the rain to their property. They knew it wasn’t safe with the storm, but it was safer than staying and changing again. They still didn’t know what was happening to their bodies.
“I hope Ian finds his family okay.” Jacob yells through the heavy rain.
“Me too.” Sasha says.
“What made you have sex with him?” Jacob asks. “You always turn guys down.”
“I asked him.” Sasha says. “I don’t know, I guess with him being bi, it just made me more comfortable. I hate to think it was the changes that made us do it. I mean, I didn’t even notice the change until after.” Sasha then thought about Jacob’s change. “How did you change?”
“I was looking out the window trying to drown you out when I saw a black horse by the tree line.” Jacob replies. “There was a flash of lighting and I started feeling pressure down there.”
“So, a horse gave you a boner.” Sasha jokes.
“No!” Jacob shoots back. “I had started growing first and the boner came after my pants started ripping.”
“Wow.” That was all Sasha could say. “Hey, there is our fence line.” She yells at Jacob, as she points to the fence line about 150 feet away on top of the next hill. “We are almost there”
Unknown to the siblings, the Black Stallion had followed them from the barn and was watching them from a patch of trees nearby.
As they are running for the fence, Jacob trips and falls face first into the muddy ground. Knocking the wind out of him. Prompting Sasha to turn around, and run back to him.
Not wanting to waste the opportunity to change the siblings more, the Stallion's eyes turn a mighty shade of crimson as a powerful crack of lightning rocks across the stormy sky.
As Jacob started to sit back up and wipe the mud out of his eyes, Sasha kneeled down in front of him to help him back up. Little did she know, Jacob was quickly building another erection from his testicles growing bigger and more equine in nature. Causing him to drop onto his hands and knees in front of her, and for his pants to rip open revealing his full now 14 inch long penis. The head of which starting to flatten out and flare into that of a horse turning black in the process. Being overcome by the sensations of his penis growing and changing, Jacob starts thrusting his hips. His long penis slapping against his chest a few times before eventually climaxing, prompting him to grunt in a cross of a whinny and orgasm and start changing faster.
His seed hitting Sasha in the chest and face, some which flying into her mouth. Sasha finding that she kind of likes the taste of it, while she tries lifting Jacob back onto his feet. “We need to get out of here, right now.” She yells at Jacob. While she also notices that her vagina is starting to feel warm.
Sasha also begins to notice her brother's ears starting to grow into points, and his pants and underwear finally ripping apart as his legs and butt continue to grow in size. Recognizing the urgency they both start running again.
