You can't beat the classic, Ty thought. He put the image to mind and immediately started transforming. He growls and snarls, face shifting into a wolf's while his body gains more muscles and height. Black fur sprouted and covered his whole body and a tail sprouts above his rear. Finally the shifting werewolf's cock grows to a solid 12 inches and 5 inches in width, the whole thing molting and forming into a true canine shaft. With a loud howl, his transformation was complete, his hand quickly grasping his huge shaft and starts furiously masturbating.
"Ggggrrrrrrrrr fuck yeeeessssss!" Ty growls with pleasure shooting all over his body, glancing around to see who or what he can fuck. He finds a human male who was jacking himself off as cum leaks out of his asshole, indicating that quite a few beasts have already had a turn with him. Without hesitation, The new werewolf grabs the smaller man, pushing him on all fours and shoving his cock inside his leaking ass.
"AAAAOOoohhhfFUCK!! FUCK MY ASS PLEASE!" The male begs, arching his rear for the werewolf to pound more of his tight butt. Ty growls and starts his thrusting with ease, the cum that was already inside the human made it easy for the beast to slide in and out of his ass with no friction at all. "THIS IS AMAZING! OH I LOVE GETTING MY ASS FUCKED BY WOLF COCK!!"
"GGGRRRRRAAAAAAHHH I'M GONNA CUM!!" Ty roars out and gave one last thrust, hist huge knot sliding into the tight asshole to hilt inside him. "AAAWWWOOOOOOOOOOOOOOOOO!!!!!!!! The werewolf climaxes and floods the male's bowls with his thick seed. Rope after rope of wolf cum started to inflate the human's belly, causing him to faintly moan out like the slut he is. Ty finishes cumming, leaving the human's belly to look like he was pregnant. He decides to leave the human stuck on his dick for a moment, pondering on what other debauchery he can partake in.
