While the VR helmet was on your head, you could see images of an open pasture, where you could see a bunch of bovine beauties eating grass, or having sex with each other. You didn't know it yet, but the VR helmet was mind controlling you, and changing your sexual interest as you were now wanting to be fucked by a bull.
While on the other side, a syringe came down, and poked you in the butt, but to your luck you didn't feel the pain after you were injected with something the syringe had inside it. Just then, the scientists managed to turn off the conveyor belt you were on, and turn off the helmet you were looking through, while shaking yourself awake. Your butt inflated once the syringe was removed, and you felt your own penis shrivel away, replacing it with a cows pair of lips easy for a bull to penetrate.
