Mary picked up the vial with a picture of a black widow on it. "maybe I'll change into spider-woman" she laughed as she drank the contents of the vial. Nothing seemed to happen, just as she expected. Mary decided to go to bed. When she removed her shirt, she saw a red hourglass tatoo on her stomach.
"How did that get there" she thought to herself. Then she started to cough. As she coughed, silk shout out of her mouth which then started to surround her body. Within minuted she was encased in a silken cacoon.
While in the cacoon, Mary felt her body change and then pssed out.
Several hours later she awoke and freed herself from the silk cacoon.
When she emerged from the cacoon she saw herself in the mirror. From her stomach up she was perfect, large breasts, flat stomach, beautiful hair. THe only thing that was different was that she had compound black eye and a pair of fangs. From the the waist down she was a black widow complete with eight legs and a spinner that produced silk for webs.
She loved her change. She now stood at 6 feet tall. SHe had super stength and saw much better than before with her nedw eyes, and she was beautiful. She started to decorate her room when she heard her room mate come home...
