As Carrie watchs John pound away into the shewolf for all he is worth she decides she needed to change as well. As she reached for the bottle of potion she saw that John was now a full werewolf nothing left human was showing from the claws at the end of his toes to the pointy ears at the top of his head he was all beast. As he slams into the clerk over and over again she wants him more than ever.
When she takes a sip of the potion she feel the changes start from the inside of her body first. Her heart rate begins to increase faster and faster as her stomach does flip flops, the heat spreads down to her core and then erupts out to the flesh in a wild feral fire. Hair begins to erupt all along her body with a soft pale red color tint to it. It thickens dramatically in seconds first at her crotch and then between her breasts till its completely covers her body in a fine red sheen.
As she runs her hands down over her breasts and stomach she notices the beginings of new nipples emerging and orgasims as she rolls them slowly between her clawed fingertips. As she begins to come down she doubles over from a new wave of pleasure when her tail begins to erupt from her bottem. As her body finishs the transformation she lets out a long slow howl that coincides with anouther orgasim.
With this John takes notice of his wife he looks down at the blond shewolf and see that she is nodding to him. She tells him in a low gravely voice " You shud finish whuf her yur furst time." John grins as much as possible and slowly pulls out, he realizes for the first time just how much larger he is now. If the women had gained in size he had doubled that at nearly six and half feet tall now he was stonger than he had ever dreamed and could feel his muscles quivering down his whole body. His cock was now a monster in its own right nearly 10 inches sticking out of his new sheath he slowly rubbed it and could feel there was some more to go, his knot was not even out yet he knew what that was for and right this minute he planned on useomg it.
He walked over to Carrie as she came to her senses and gasped as she wrapped her tounge all the way around his shaft and slowly lapped the unbelievable taste from his cock and balls. Not able to stand anymore he moved behind her and slammed deep the first time. Carrie wimpered and then began to growl and moan as the picked up a rythm. The blond werewolf kneeled in front of Carrie and began to howl as Carrie stuck her nose and then seven inches of her tounge even deeper into her with motions that soon had her convulsing over and over again.
John began to feel his balls tighten and knew he was near and instict took over. He grabbed Carries hips as hard as he could and pulled her back against him as he thrust forward as hard as he could. The ball of his knot burst out of his sheath and deep into his wife and began to swell as he pumped more and more of his canine fluid deep into her womb. As he began to bite down inbetween Carries neck and shoulder he felt her clench his cock with new strength as she orgasimed again. As he began to sag his cock pulled tight against Carrie's hole and they both rolled to the floor together unable to seperate with each tug bringing more spunk from him and small shudders from her.
As the blonde stood up she began to change back to her human shape and smiled as she looked down at the couple locked together in a beastial embrace with a knowing grin. " You two where great don't worry about being stuck he will shrink and a half hour or so. But you probably will not change back for a few hours being your first time." As she put back on her shirt and skirt and headed to the door she smiled and said. " Anytime you want I can come back but I am need at desk for the next shift so I hope to see you around. By the way my name is Pam."
John and Carrie layed spooned to one anouther and began to drift off to sleep him still deep inside of her and both dreaming of the days to come.
