Ty suddenly realized that this provided a wonderful opportunity for further humiliation. Silently, he made his wish.
The lion suddenly stopped, sniffing the air. Dustin continued to back peddle, failing to notice the sudden drop in pressure in his pants in his panic. Unfortunately, by keeping his eyes on the lion he failed to notice a tussock of grass directly behind him and fell heavily on his ass.
The lion, seeing him fall, suddenly pounced and landed straddling the terrified teen. As the spectators screamed in horror, Ty chose this moment to make all of Dustin's clothes vanish. Instead of tearing into the boy, the lion leaned his great shaggy head down to the boy's crotch and started to lick his balls. Even as Dustin's rod stiffened from the raspy feeling, the pressure that the rough, wet tongue exerted seemed to have a gradual effect as the moderately sized balls began to be shoved back into the body.
As the ministrations continued, they disappeared all together briefly leaving Dustin with crotch featureless save his rod. The lion shifted slightly to start licking the rod instead. As the penis also began to melt into the skin, the slit at its tip began to lengthen and deepen. By the time no vestige remained of the once proud oak, a long vertical slit was all that remained. The saliva, however, seemed to continue to affect the region leaving the inner skin folded and working deeper inside, forming an entire reproductive tract.
Throughout the experience, Dustin's shallow terrified breathing subtly changed, becoming less terrified and more needy. When his genitals finished their transformation, the lion stepped back, almost as if to admire his handiwork. Dustin slowly rolled to his knees, still panting. Despite an inner voice screaming and cursing him to stop, he couldn't help looking back in his addled state and waiving his ass in the air in invitation to the obviously still interested lion.
As zoo keepers frantically dashed by towards the hidden entrance at the back of the enclosure, Ty watched in amused fascination.
