Mary rushed back to the vials looking for vials to reverse the effect of the vial. Not looking, she swallowed a couple of vials at once. What she had swollen was the snake, female and growth vials.
Mary fell to the floor as her legs merged together to form a long snake tail aboud 45'8" long at her best estimate. As the tail thickened at her waist she heard a cracking and felt pressure and stretching all around her, confused Mary looked all around looking for the source. Then she felt the pressure relieved as the pressure stopped only when she heard a large rip. Which it so happened that the rip was her human skin ripping apart to expose her new reptillian skin to the new world. The cracking was her bones dislocating, growing and relogcating to their spots. Mary noticed that her body grew to the same size as her waist where her snake tail met her once human body.
Mary looked in awe as her breasts grew to FF cups. Mary grew spikes on her body, her eyes turned reptilian and she grew fangs.
Now what does she do?
