Todd watched in horror as his love changed and warped into a were-fox before his own eyes. The burning change that washed over his own body making him feel sick as the red fur swept across his shoulder and down along his own arms only to turn black at the elbows. The changes continues down his chest as the fur there became snowy white.
Astrid was bucking back harder and faster onto the male feeling the thick bulge of his knot pressing to her dark vulpine folds stretching her as the needful male worked himself into her his knot swelling and tying himself to Astrid as he climaxed into the once human female.
Todd's nose began to twitch at the scent of the males rutting into the vixen and shivered as his body became aroused and filled with thoughts of sex, his changing hand drifting to caress along his own length which seemed to feel different. As Todd looked down he watched in horror as his chest swelled and his cock became smaller before his own eyes. "Hmm look love, another vixen for me." The were-fox smiled as Todd's chest blossomed and a pleasure swept over the changing mans body. Soon two more sets of breasts began to grow under the first pair that Todd had grown. Astrid could only yip in response as the were-fox spilled himself into her body, her eyes watching the human cock vanish into Todd's groin, his sac pulling up inside and causing him to grip her stomach as the new internal organs grew making Todd's gender change complete as white fur now covered the swollen folds of her sex.
The were-fox smirked and licked his muzzle. "Hmm, I'm going to finish changing you myself." Slowly the were-fox pulled himself free of Astrid as his knot unswelled. Todd unable to think straight was tring to get ahold of herself before something else happened.
