Mary had an idea in mind. She was intrigued by spiders after reading Spiderwoman and Spider Gwen comics. She knew Jeff had read some stories about driders but Mary wasn't so sure about becoming that much of a spider. She picked up the Spider vial and thought about drinking only part of it. After thinking about it for a moment, she decided to take the Woman vial as well to ensure she didn't become too much of a spider. Without telling Jeff which vials she had, she popped the tops off with her thumbs and poured the down the hatch together.
Mary could feel the first changes but they weren't anything animalistic. She felt her chest expand slightly, her breasts growing a size and firming up. They strained at the t-shirt she was wearing. Her legs and arms took on a more toned appearance. Mary examined her hands and knew she could make a hand model envious. She was already attractive, but her skin became flawless. Her shoulder-length hair grew several inches and turned from brunette to dark black.
Jeff watched in awe. "You look...amazing. I thought you were beautiful before, but wow..."
"This is just the beginning" said Mary. The changes so far seemed to reflect only the Woman vial. What about the Spider vial?
Suddenly Mary doubled over and clutched her torso. Jeff rushed to her. "Are you okay?"
"I think the major changes are beginning" said Mary. "I feel like I'm torn apart."
Mary's torso slowly stretched several inches, leaving her midriff exposed. Then her chest heaved and her shirt began to strain and finally tear from the front down to the bottom, revealed extra pairs of breasts. Mary pulled off the ruined shirt like a vest. She could feel the changes weren't finished. Out from her sides grew two extra pairs of arms in line with her second and third pairs of breasts. Mary stared at her extra arms then realized what had happened. Spiders have eight legs and now Mary had eight arms and legs, along with eight breasts.
Curious, she simultaneously felt her six upper breasts with her six hands. They all felt quite sensitive and she enjoyed fondling them. Then she felt Jeff's hands on her lowest pair of breasts.
"A bit of a weird spider woman but I like it."
