Your Girlfriend is Transforming into a Horse (Patreon)

You and your girlfriend thought it would be fun to explore an abandoned farm just out of town. She went to check out the barn while you got your backpack out of the car. You hear a scream coming from the barn. You run as fast as you can. Your girlfriend is really sweaty. She said doesn't feel good. Then her body just starts growing. Her shirt and pants are getting so tight. Her arms, breasts, legs - everything was getting bigger. She screams and tells you to help her. You rip off her shirt. You can see how insanely muscular she is becoming. Then she grunts hard and moans. Her nostrils start flaring uncontrollably. You watch as her nose grows bigger, nostrils expanding, and then pushing outward with her mouth to form a snout. Her ears also start moving up to the top of her heard. It finally dawns on both of you that she is becoming a horse - or at least some sort of horse hybrid monster. Then she says in a deep voice, "Ugh..... what the fuck... I'm feeling so god damn horny..."
