"No, nothing has changed. I'm a straight man and I like women." Jeff firmly said. "It's just..." He hesitated and Mary raised an eyebrow. "It's just that sex as a woman feels a lot more better than as a man. At work or at home, I feel this emptiness inside me that cannot be satisfied with a simple masturbation. I tried fingering my asshole but it's not the same. Then, I realized I can get rid of it as a woman and the feeling leaves... for a while. It's like after the orgasm my minds goes back to normal and I felt repulsed of my actions."
"Hmm... It sounds you're addicted to have sex as a woman." Mary said while she crossed her arms. "Would you help me?" Jeff pleaded while he offered her a male vial. He has the female one at his other hands and he seemed eager to drink from it. "No, I won't. Don't misunderstand me, I also enjoyed having sex as a man but it won't make any good to you in your current condition. You should try some days of abstinence." She stood up and took all of her sex toys and hid them from Jeff. She did the same with the vial box.
Jeff knew that she would try to take the male and female vials he had in hands, so before that he poured their content in two bottles of water and then he hid them under the sink. When she came back, she took the vials from him, their magic properties made them get full again, so she didn't suspect a thing. "It's for your own good, babe." She said before she kissed his forehead. "When you surpass this problem, we could try another kinky transformation. I was thinking about doggy style. Literally." She winked.
Later that night, at bed, Mary start to kiss passionately him and caressing his dick until he was hard. "I'm going to remember you how good was having sex with me." Jeff followed her and they ended up having a good night of sex. She felt fulfilled but he didn't. A few hours later, she was happily sleeping while he was staring at the ceiling wondering why he isn't enjoying sex like before. He started stroking his dick but despite it got hard he didn't feel aroused. He stopped and left the room decided to take the vials from under the sink.
He drink just a little bit of the female vial, the enough amount to turn his male parts into female ones. He started playing with his clit and despite it felt way more better than the sex he had a moment ago with Mary it wasn't enough but he didn't have Mary's toys anymore and turning her into a man was completely off the table. He tried to get something useful at the kitchen but it wasn't the same and in some cases it was even hurtful. He gave up, restored his male parts with the male vial and went back to sleep.
Sleeping wasn't as helpful as he expected. In his dreams, he was having sex as a woman while hundreds of men where waiting for their turn with him. He was sweating, moving and even moaning while he's asleep, fortunately Mary didn't wake up until the sunrise when Jeff had already stopped. She took a shower, changed into her job uniform and left the home. Jeff woke up almost an hour later, he was working at home so he didn't mind about the shower, he was thinking again about having sex as a woman. But how?
