Liz watched in her private cinema everything her cousin did with his girlfriend, despite him not being a guy anymore. At first she didn't believe the story about the aphrodisiac pill that could turn someone into a mutant, but after what she saw she had no doubts it was true and was grateful that she had asked Brenda to give her one earlier. She had realized that her clothes could be ruined with the transformation, so she undressed before swallowing the only pill she had with her.
Trying to guess what she would become, Liz felt the effect as she felt extremely horny, and soon she felt the changes in her body begin. She grew taller, reaching 10 feet in height, as her nails turned into claws and a tail grew above her ass. Before she could look back she felt her face change as gray fur grew all over her body, her face lengthened into what was clearly a muzzle, her hair fell out and her ears moved up her head, becoming more pointed. She then felt a wave spread through her body, which was more changes taking place all over her at the same time, her torso got wider making room for a lot of breasts that grew on it, on her sides two new pairs of arms grew just below the original set, she also grew two new heads allowing her to see from three different viewpoints at the same time, and finally three dicks grew between her legs followed by a ballsack in which six testicles were deposited one after the other.
Liz could feel her transformation was complete, she was very horny and her dicks were rock hard but she held back, she wanted to see the full extension of the changes she had undergone. She left the private movie theater and walked through the mansion, she passed several employees on the way who looked totally surprised at her, some even made faces in astonishment, as she went to her room to look in a mirror.
Looking at her reflection she saw that she had changed to the point where there was not a single trace of what she was left, making it impossible to recognize her. She had become a 10-foot tall, three-headed anthro wolf with three pairs of arms, no trace of humanity was left in her heads. 16 breasts were on her chest in a 4-by-4 formation and a trio of 17-inch lupine cocks pulsed hard between her legs, accompanied by a ballsack containing six melon-sized testicles inside.
Having seen well what she had become, Liz decided it was time to deal with her boner and wondered how she was going to do it.
