You fall to the floor and feel as more changes occur. You look over at the boy as he succumbs to the need to pull down his pants.
He does this allowing his newly formed tail to swing free. The boy starts to age faster. His small willy starts to grow larger and larger until it turns into a mans penis. his formerly hairless body quickly becomes covered in pubes. His body then grows until hes at least six feat tall. His testicles are covered in hair and dangle halfway to his knees. He then groans as all his muscles become ripe and bulging. Unable to stop yourself, your cock gets hard looking at this naked donkey man. You leap up on to the man/boy and try desperately to locate his anus. You find it and thrust deep and the man/boy groans not in pain but in pleasure. You keep thrusting away incredibly turned on by this scent you can smell. The man/boy starts to get hard underneath you and starts to wank while this is going on. His cock gets larger and thicker and his testicles go black. You suddenly bray as you cum into his ass, and you collapse seconds later onto his hairy back. Momments later the man/boy gasps in surprise at his very first orgasm. You try to pull out of his ass, but your cock seems stuck. As you pull out you realize that the base of your cock i stretching the man/boys ass hole up to 3 inches. You feel your testicles. They are huge and feel all rough and leathery. the man/boy and you then collapse on the floor as exhaustion hits you both. the noise of braying wakes you...
