This was all so weird. Derrick was about to push off the bed and get away from this very amorous beast, only to get pressed down as the huge animal slid over top of him again. But this time he felt the hard tip of the lion's penis press against his spit-slick rump and was alarmed. "Wait a minute! I don't want..." Then he gasps as the lion pushed into him with a powerful thrust. It was confusing, for Derrick felt pain and pleasure, separate at first, then merging. The lion began humping him, and Derrick started sliding back and forth over the sheets.
This went on, the lion continuing to thrust, but Derrick felt like he was moving further back and forth each time. And a curious pounding started up in his legs, his back. The pleasure was coming from his belly and chest, the pain fading. Dazed by the constant pressure and pleasure, the boy saw his arms get shorter, drawing into his shoulders. A mass was building in his gut, pressure of built-up fluid. There was a short stab of pain as his heart stopped, and the rhythmic pounding got louder - the lion's heartbeat. Derrick was fully covered by the lion's chest, unable to do anything as he was rubbed against the mattress. The lion seemed huge now, more than four times Derrick's size and growing.
There was a sliding sensation over his belly, and Derrick's head started to pull into his shoulders. A jet of translucent fluid shot from his mouth, like thin mucus. Other senses were closing in - his skin was now incredibly sensitive and he could taste the fluid, but sight, sound, and smell were almost gone now. It wasn't a thick, ropey fluid shot from what had been Derrick's mouth that he realized it was cum, and he was almost fully changed into the lion's cock. Awareness closed in, and then he was stiff, swinging in the air as the lion shuddered in another release that splattered over the bed.
Derrick was about to spend at least two weeks as the lion's cock!
