Mitch was stunded to think he had become a ass and even more feared that he had changed sex. Turning to face Nathan, Mitch could only bray. No words came from his mouth. The more she brayed the less she understood Nathan's speech.
Nathan feeling ever so much as desire to mount Mitch since she was wafting a odor of sex. Nathan's ass self wanted this female so much that his cock was tight. So very tight that it impeeded his walking.
Mitch degrading mental self felt a need to be mounted. Yet the male human that was left had little say as to what his body did.
Turning and evasive Mitch stayed away from Nathan's shaft. However Nathan had enjoyed such experiance many times before and moved in for the thrill.
Mitch turned left as Nathan went right and bounded onto Mitch's rump. Inching alone as the female wiggled Nathan final movements and Mitch felt the thrust of a hardy Jackass cock push deep to his G spot. So delighted was this touch, Mitch lost all control and pushed her rump back onto the aching shaft. Further and further till Nathan's sheath moved between Mitch's sex lips.
The mating, mounting of two animals conntinued way into the night. Nathan still able to talk counter thirty four times mounted and thirty three times successful.
As midnight came Mitch regained his human form. Yet feeling very full his stomac now owned sixteen pounds of Jackass sperm. Mitch started to puke and tasted the yellow-greenish semen of the Jackass 'friend'.
Looking up at his suitor and mate Mitch asked for one last touch of Nathan's cock. Reaching for the Amulet and touching Nathan's overworked cock, Mitch wished Nathan to be more endowed and exceeded pleasured as he stayed in Jackass stud form. Also Nathan could change back to human form anytime he desired.
