Imagine that Johnny has a huge lust for horse dick. The smell, the texture, he just can't get enough. Not being able to walk, it feels almost safer to be underneath the powerful legs of a horse, even if it's technically more dangerous. But that also adds to the thrill, which also comes from the taboo of it. He really loves his horses.
Imagine that he needs his fix, he's addicted to sucking horse cock, during SBR, and he can't get away from Gyro for long enough. Finally, one night when Gyro's asleep or so he thinks
Johnny starts massaging the sheathe and balls of Slow Dancer. He's an older horse but still has no problems getting hard from Johnny's touch. His cum's still as virile and thick as ever, as Johnny's face can certainly attest to. The smell of the horse's dong makes his mouth water as he takes the spongy head into his mouth, lapping at its pisshole.As he sucks and jerks off the horse he doesn't realize Gyro woke up and is staring at him in disgust, too horrified to say anything.
