While John was staring at the shewolf he was unable to think straight for only a moment. Her wild and musky scent filled his nose and while he pulled his straining cock out of his wife's wet tunnel, he could not take his eyes off the shewolf's wet hole.
A wild desire burned inside John's groins and despite he'd filled his wife with his sperm just a moment ago, his penis wasn't softening up a bit as his arousal was too strong at the moment.
The shewolf turned her canine head and started to growl softly, while still showing her wet mound to John.
John slowly started to push his horny wife to one side. Carrie did'nt resist, as she was still staring at the shewolf's hole she'd just licked so furiously only some moments ago while John fucked her own vagina from behind.
Then John took the vial with the transformation fluid from the desk where the blonde woman had placed it before changing into a creature half wolf and half human. He took a small sip from it, then placed it back onto the desk. His cock was still fully errect as the musky smell of the shewolf was intoxicating and arousing at the same time.
The effects of the potion affected John's body only a moment after he gulped the spicy fluid down his throat and he was unable to supress the desire to snarl and growl like a canine while he shed his last remaining clothes in a hurry. Dark-grey fur was starting to sprout all over his body and sharp claws grew from his fingertips.
Carrie was still kneeling on the ground between the shewolf and her changing husband and her eyes grew wide as she witnessed John's errect penis change into a wolf's huge member. The skin turned pink and his ballsac grew connected to his lower abdomen as the foreskin formed a canine sheath.
John felt the transformation as it rushed through his body and changed his mind, too. His human thoughts got erased by a canine point of view and strong instincts to mate and reproduce kicked in one by one.
Ignoring his aroused and awed wife, John closed in on the shewolf in heat and grabbed her hips with his furred claws.
While his face was still changing, John pushed his canine cock up to the blone shewolf's dripping mound and positioned the tip of his member right at her demanding flesh.
Then, with a growl, he pushed his wolfish cock right up her hole and started to fuck her like a maniac.
Carrie witnessed her husbands transformation and her own arousal grew and grew by the second. Soon she was pushing her fingers up her own wet pussy while observing John turning into a wolfman and fucking the blonde shewolf furiously.
