your girlfriend then grunted as her breasts receded into her chest, and massive pecs grew in their place, tearing her shirt to ribbons. her body filled out with muscle as her height increased to 8 feet, shredding the rest of her clothes and leaving her in only her panties. her hair receded into her head stopping at her ears and looked wild. her face became masculine as body hair grew all over her, and an Addams apple grew on her neck. she now looked like an athlete, and she then grunted and thrust her hips repeatedly. her vagina closed up and then pushed out till she now had a hairy scrotum in its place, balls the size of bowling balls dropped into their sack, popping out of the sides of her underwear. her colitis grew in width and height till it was now the size of a bowling pin, breaking her panties in two.
"is that it," you asked, "yeah guess that's it *grunt*, then again." your girlfriend replied in his new manly voice. the changes were not over yet though. his cock shifted and mutated into a canine cock. his balls grew dark thick grey fur over them. short light grey grew around his pelvis as his spine extended into a thick wolf's tail. his pubic bush becoming more thick dark grey fur as the light grey fur spread down his legs. his stance shifted to the balls of his feet, and his feet then became that of a wolf. thick dark grey fur grew in place of his treasure trail and chest hair while light grey hair grew on his sides and back. his pit hair became that same thick dark grey fur as lighter fur went down his arms. His hands shifted to a mix of human and wolf, nails becoming claws as pads grew on his palms.
the fur soon covered his entire head, and the hair on top of his head became dark grey fur. his face pushed out into a wolfish muzzle, teeth becoming sharp and his nose becoming black and bumpy. his ears then migrated to the top of his head as his eyes turned yellow. he let out a triumphant howl as he cumed from his cock, splattering it over her room barely missing you. " *sigh* that feels much better, oops sorry it was just so pleasurable that I couldn't hold it in," your girlfriend said as his cock returned to its new sheath. "It's OK so how long do you stay in this form?" you ask. "all night which is why I asked you here. I know we've been dating for 5 months but I think this might be a deal breaker. I mean I'm not even a girl in this form. but I want to give this a shot if you will what do you say." he asked.
you didn't expect this your girlfriend was now an 8-foot werewolf man. but the question is what will happen next?
