Dave writes, "Janet is a muscle builder with a body larger than Arnold Schwarzenegger's in his prime."
As he looks up at Janet, he finds that all of her muscles are now expanding. At the same time she is stretching out taller and taller. Her biceps and calves bulge as every striation in her quads thickens. She quickly develops a solid washboard stomach. Her modest B-cup breasts are dwarfed by the mountainous pectorals that spring up beneath them. Very soon, she has gone from athletic and trim to beefy and ripped.
When the changes stop, Janet is now 6'3" and 275 pounds of pure muscle. Her neck is twice as thick as her head, which still remains as feminine and pretty as ever.
Dave chuckles to himself. "Pose for me, Janet," he commands.
Without hesitation, the naked behemoth of a woman before him clenches her massive muscles and poses for him like a pro. He laughs out loud. "God, you look ridiculous now."
Dave shakes his head, still laughing, and asks, "So, how long have you been lifting weights?"
"Since I was a girl," Janet says. "My whole family works out all the time. I guess it's in our genes."
"I guess it is," says Dave in agreement.
"I've always been very muscular and tall. Some of the boys in grade school used to tease me because I was so big, but they stopped once I beat them up a few times."
"That'll show 'em," Dave says and starts laughing hysterically. It's just too much. His once chubby old secretary has become a young musclebound amazon.
