Mary was your typical neighborhood MILF, long blonde hair, large F Cup boobs with a bit of sag to them and an hourglass figure with a large curvy heart shaped ass to top it off. She lived in suburbia with her husband John and her two teen aged kids Steve and Julie. She was alone most of the times during the day, left to tidy up the house and stay fit, but also left her bored most afternoons. Her friend had gotten Married a couple weeks ago, and at the bachelorette party someone had spiked the punch with TransFun, the party quickly became dogs as they left the unfenced backyard and wandered the neighborhood in tattered clothes. Mary had let her doggy instincts take her over to a local junkyard where she was ravaged by a pack of stray dogs the pack having their way with her even as she reverted back into her human form. The experience was amazing to her, she hadn't had sex that good since she had been on the cheerleading team back in high school and fucked the football team.
Since then she had been ordering it from a second hand supplier to cut costs on a shorter transformation time so she could change and get her fill of sex and revert back all before her husband and kids got back home. She had noticed a bit of unwanted side effects. She had gotten much more hairy and she started to smell a bit different too, especially when she was wet. She was less interested in sex with her husband, she had started to look up videos of dogs breeding and pleasuring herself. She ignored these changes, the feeling of changing and fucking was too good for those small things to stop her.
She looked at the vial in her hand, chugging it quickly before looking up to the bathroom mirror in front of her, smiling before sticking out her tongue to see it expand. She jumped as she heard the door downstairs open and close, swearing under her breath as someone was definitely home a bit too early...
