She felt itchy immediately, like her hair was standing on end, threatening to start growing and going wild. Keith, noticing his girlfriend’s transformation starting, snapped his fingers as staff in the vicinity disappeared. The wolf symbol on his wrist started glowing as his dick popped out of his pants, turning red and reshaping into a more canine look. He rubbed his slightly canine dick against Mary’s pussy, looks like she took his advice about not wearing any underwear. She felt him change as he rubbed against her, which fired up her other changes too as her ears and tail revealed themselves. He removed all his clothing and started licking her back as his tongue got longer and longer, his face reshaping into a wolf’s muzzle.
At this point, the entire venue was wondering what was happening, there was no band on stage and there was a moaning sound coming from somewhere. All it took was one casual glance from a random audience member and the entire audience panicked looking at the two wolf creatures fucking in a booth. They tried to escape to find that all the staff had started transforming into similar wolf creatures as well. Just when they thought it was all over, the actual band they came to see appeared on stage as werewolves as well, all of them massive with either long, musky, red knots or E+ cup tits. All of them put their hand up and spread as wide as possible before all of them grunted. Suddenly, a thick, visible musk came from the wolves and filled the air. As the others finished transforming, they started jerking themselves off or fingering themselves until they could squirt. Anyone caught in the blast immediately felt themselves change, fur sprouting from their chest or their noses turning black. Keith came inside Mary as the crowd slowly transformed into werewolves. The screams of terror slowly died down and turned into moans and grunts of wolves having sex. As Keith left his knot inside Mary, the same symbol appeared on her wrist, as her brain went out of feral animal mode and into a more horny furry mentality like her boyfriend’s. Mary got a good look at her body as Keith pulled his knot out of her. He must’ve dumped gallons of cum into her, as her once muscular chest now started to look soft and pudgy. The skin under her fur no longer looked taut and lean, as even her face felt rounder. There was even a slight amount of pudge on her fingers and toes. Keith leaned into her ear and told her, “Consider this our impromptu wedding. Love you babe.”
After the concert (and turning back into hairy humans) Keith and Mary had a lot of snuggling and kissing. Mary even kept her pudgy form even after turning back. Keith kept massaging her fat sensually and could barely keep his hands off of her. She kept kissing him until they eventually ended up in a couch where they cuddled themselves to sleep.
