Chris tried to act casual as he rushed to the kitchen. picking up the vial he read what it was. "dragon vial, form: anthro. drinking this will turn the person or animal into a humanoid dragon. turn to back for possible side effects" Before the 16-year-old could turn the vial around he heard his mom shout. he ran back to the dining room and saw his mom sitting down.
"Mom, what happened?" Chris said as he noticed his mom seemed larger. her bathrobe now straining slightly from new muscles growing. her mom seemed to be aroused as her nipples tented her clothing. She grinned as she let out moans. before Chris could do anything Katherine's clothes got even tighter.
this revealed two things, first her breast seemed smaller suddenly and the second was on her crotch. a bulge was visible before her clothing began tearing. this revealed what he feared a penis was growing from her shrinking pussy. the teen didn't know if he was more shocked or disgusted at what he saw. the moment his mom saw his new cock he grabbed it and began jacking off.
running back to the vials he checked the slots and found a dragoness vial. realizing what was happening to his mom he went back to the kitchen with the case. picking up the vial he flipped it around to see possible side effects. he was shocked at how much there was as the label wasn't that big. 'this thing can alter someone with magic. surely the label can be enchanted too' Chris thought as more moaning happened in the dining room.
his mom moaned as his pussy sealed shut. however, it didn't stay barren for long as a hairy scrotum grew with two large orange-sized balls inside. Chris ignored his mom's moans and read. "side effects: will become a male dragon no matter what. size increase up to 8 feet, larger is rare but not impossible. increase strength and possible magic depending on the type. may gain excessive body hair or complete loss. extra dick or internal testicles are possible. personality changes and/or mental changes are also possible. increased libido." Chris couldn't believe this but given how his mom was changing he kept reading.
"Additional vial intakes will result in one or more of the following: increased size ranging from 6 inches to a foot with each consumption. body hair growth if the hair is kept. muscle increase. duplication and/or increase of genitals. increased masculine features. if mental/personality changes happened it could increase these. magic increase or appearance." Chris then read something that made him gulp. "warning do not mix vials. This may have undesired if not dangerous effects. smaller vials such as growth, shrinkage, hair, form, and libido are permitted after initial transformations. if a form is undesired take human form: gender here." Chris finished and realized his mom had stopped moaning.
going back to the dining room he saw a six-foot man covered in cum and scraps of light blue cloth. his body was covered in hair and muscle. he kind of looked like his mom's brother if she had one. he seemed about ready to pass out. "what was in that coffee," his mom said. "I'm so sorry I..." Chris started before his mom moaned more. the man's cock seemed to grow and take on a less human shape. 'Guess the male part was first' Chris then ran to get his mom a towel to cover himself with. when he came back he saw a...
