“What do you mean?” She asked in a deeper voice and they looked at each other in disbelief.
Jeff saw that Mary’s face was slightly different, her jaw seemed a little more angular and her lips where thinner. Mary looked at her hands and saw her small nails and larger hands.
“I can’t believe! It works!” Mary said.
“What? Are you turning into a guy?”
“Can you explain this?” Mary pointed at her groin and they saw a small penis where her clitoris were just moments before.
“Amazing!” Jeff said. “But disgusting too! I don’t want to make out with another man!”
“Well, it is still me up here.” Mary said as she tapped her forehead.
“Yeah, but not where it counts.” Jeff pointed at her chest and Mary noticed that her D cups breasts were now just A cups.
Mary stood and ran to their bedroom to see her changes on a mirror. She noticed that her muscles were bigger and her shoulders were broader. Jeff followed Mary and was perplexed by how much she was changing.
“You are really changing into a man! What will we do now?” Jeff asked.
“The changes last for 24 hours as the note said.” Mary answered in a voice that startled both of them. “We have two options. One is to wait until this vial wears off tomorrow. The other is to you to drink a female vial and then we can test out our new bodies.”
