The lion stopped the slobbery licking and put its forepaws on the bed on either side of Derrick. Then it shifted forward. "Oh, man. You are not gonna..." Then Derrick gasped as he discovered that the lion WAS going to try mounting him. There was no place to go, and he braced himself for the assault. The beast prodded his butt a couple of times before finding his anus, and then Derrick cried out in pain as the lion's thick barbed cock was shoved into his body.
Instead of mounting him, thrusting back and forth, the lion just lay down, nearly smothering Derrick against the bed. The huge cock started throbbing, and Derrick found the pain was fading. Now he felt warmth and pressure, and a slow sense of dull pleasure spread up through his body. The throbbing moved down his legs and all the way to his toes. It was a nice feeling, but something was weird. It felt like his legs were drawing up, getting shorter, and he felt damp and sticky. Was he sweating? No surprise uhnder the massive beast, but it did not really feel like sweat.
Shifting a little, Derrick caught sight of his arms - they glistened with a whitish, slick substance that smelled funky. Then he gasped as his fingers melted away into a mass of the sticky fluid - semen! He tried to scream, but instead of sound, a gush of semen shot from his mouth and splattered the mattress.
The lion seemed to take that as a cue, for it backed off the bad and dragged Derrick back with it. twisting around frantically, Derrick managed to look back. His legs were gone, his body ending inside the sheath of the lion's now-gargantuan penis. Testicles the size of grapefruit swelled out as Derrick's body drew further in. He shuddered and spewed another gush of semen, feeling his arms pull in as he did.
Derrick felt like he was floating now, unable to find any sense of body or self. More semen spewed from his mouth, but he did not feel pleasure of ejaculation. The lion roared with pleasure. Instead, Derrick seemed to be less, somehow. Another roar, another shuddering ejaculation by the lion, and Derrick felt stretched, confused, aware of too many things, too many senses, too many Derricks. not hundreds, or even thousands. Millions of Derricks! Billions of Derricks. Some were already fading, the splatters on the bed and floor wriggling unseen with their last bit of life. The throbbing continued, all that Derrick was aware of now. The lion's heartbeat. Another shudder, another lessening. He had become a mass of lion sperm, the massive testicles drawing in as much as they could hold, and the rest of Derrick being spewed out to die. He was aware, but now his essence was divided.
Derrick was warm, contained, feeling a need to find something. An egg. He must find an egg. The lion had to mate with a lioness and let one of the wriggling sperm that now made up Derrick to fertilize her. The lion roared and shuddered, sending more of Derrick out to fade away. If he did not mate soon, Derrick would end up as nothing more than a collection of stains.
