“Well, these vials can prove that magic do exist, and now we have a unique opportunity.” Mary said while she browsed through the options and then took a male vial into her hands.
"I am amazed at how this box works." Jeff said looking to the box.
“Only one way to discover that. If this is true, then I will change into a man just by drinking this liquid.” Mary said as she uncorked the vial.
“Are you sure about drinking that? What if it is poisonous?”
“I don’t think someone would make all of this just for poisoning us.” She said and drank the entire vial.
“You are really crazy. It would be interesting if you really could turn into some of these forms.”
“I don’t know if this will work, but I am getting really horny now.” Mary said as she licked her lips and approached her husband.
They kissed and started to make out on the living room. Soon they were removing their clothes and groping each other bodies. Jeff parted the kiss and lowered his head until he was facing her nipples. He started sucking a nipple while playing with the other. Mary moaned in extasy and felt her voice harsher. She just coughed and went back paying attention to Jeff’s ministrations.
When Jeff caressed her pussy, he felt it already engorged and moist. He left her nipples and descended to there. He licked lightly her labia, causing Mary to moan in a deeper but still feminine voice. Jeff sucked her clitoris and Mary moaned higher, almost grunting. She did not see her nails becoming shorter and her hands turning into manly ones.
While Jeff was sucking her clitoris, he felt it growing into his mouth. He was intrigued by what was going on and looked at it. It was then that he saw her clitoris slowly expanding and becoming wider.
“Mary! What is happening to you?” He asked taking Mary out of her trance.
