"Transform" Susan answered without thinking about the consequences.
"Since I feel so horny, you will transform into a bull and fill my need!" Jennifer said lustfully. Only aware of her growing need.
"No! Jen! What have you done? I don't want to share your destiny. And I don't want to become a male!" Susan screamed in fear. But it was too late. Already she could feel two small bulges growing tight againts her pants. One in the front and one in the back. Soon a tail ripped free of her pants and a bulging penis popped open the buttons of her pants. Small horns growing at her sleeves. Her face pushing forward.
"Look at how sex you become!" Jennifer said licking her lips lustfully as her face stretched out forming a cow's muzzle. Her words becoming more like "moos" every second.
"Oh no! Jen. I don't want this. But I'm starting to smell you now. You smell so goooood!", Susan said as her own face continued tu lenghten. Her ears growing out, hands becoming more hoove like. Her body began to swell stretching her tight clothes. Her member stiffening and enlarging as she smelled Jennifer the cos nearby.
