As soon as Jeff left, Mary started to browse the vials searching for a new one to change into. She was fascinated by the mythical section. The variety was so large that she felt indecisive about what to try. She definitely wanted to try some other shape on that section. There was several types of succubus, lamia, drider, centaur, dragons and everything else someone can imagine.
She thought that she could make a surprise for Jeff and soon found the perfect solution. She took the ‘Blue Hermaphrodite Succubus’ vial. She thought that it was a truly exotic being. She knew that succubae are shapeshifters so they could lure men into having sex with them. She thought what Jeff would think about her being a hermaphrodite. She knew that he also visited internet story sites with stories just like that, a female becoming male or hermaphrodite while her partner tries to cope with her changes.
Finally, she put the pros and cons on a scale and drank the contents of that vial. She noticed that as soon as the vial was back on its place it filled itself again. She was on the sofa just when she relaxed, her nipples became erect and her pussy wet. She moaned lightly and looked at her body. She saw as her nipples suddenly grew and became purple. She hurried to the full-length mirror on the bedroom. She didn’t want to lose any changes on her body.
Just a few seconds later, she saw as her breasts filled from a b-cup to a d-cup while remaining firm and round, defying gravity. She was on the edge of an orgasm when Jeff’s phone rang. She answered it and tried to remain calm while talking to him. He had already arrived at their house and was asking what he should pack for her. Mary panicked thinking that he would be back before she finished changing and asked him to pack everything she had. That should keep him away from the cabin until she finished changing. While she was talking to Jeff, she noticed a tail growing out of her rear end. The tail was one inch wide and four feet long, ending on an arrow like tip. She was breathing heavily on the phone and Jeff asked what was happening. Mary just told him that his batteries were almost gone and quickly told him to buy food enough for a month. When she hung up, she quickly turned his cell phone off and ran a hand on her new tail.
She noticed that she could move her tail and that it was strong. Then she felt something change on her face and saw in the mirror her lips filling and turning purple too, while her teeth became sharper. She ran her tongue on her lips and found out it was forked and purple. She smiled and thought that her image was a little frightening.
Suddenly, Mary felt a vertigo and closed her eyes. When she opened them again, she noticed that she was taller, maybe seven feet high. Her feet had grown too, her toes merged, and now she had hooves on their place. Then her proportions changed and her hips widened while her waist narrowed, giving her a killer hourglass figure. Her legs were smoother and longer now and she had no hint of hair on her body, except for her head. Her eyes were now entirely dark blue in color and emitted a faint blue light.
All the time she was changing, she was on the verge of an orgasm. She noticed that her nails were growing and changing into one-inch deep blue claws. She looked at the mirror and saw as her hair went from brown and long to cobalt blue, super long and luscious. It was cascading on her back in waves. She looked at the clock and saw that almost an hour had passed. Then her muscles all increased in size but her figure kept very feminine.
A few minutes later, Mary saw her skin becoming blue, in a shade a little lighter than her hair. She ran a hand over her nipples and moaned on a sultry and sexy voice that she couldn’t believe was hers. She put a hand over her crotch and felt her clit throbbing. She immediately removed her hand and looked closely on the mirror. Her clit started growing and changing its shape, but stopped when it was five inches long. It was now definitely a small penis. Mary was flabbergasted with that. She touched it and felt an enormous pleasure. She felt the base of her penis and found her pussy.
Suddenly a wave of dizziness fell upon her. She looked at the mirror and saw as two deep blue horns grew on her head and curved back. They stopped growing when they were a foot long each. Two bat like wings sprouted from her back until they were fifteen feet each when opened. Mary folded them on her back and saw that they almost reached the floor while hanging almost as high as her horns. When she grabbed her penis again, she was startled that it was ten inches long now.
Then she felt it. One hour and a half had passed and she had finished changing. She was happy that she would be able to fly again that night and to stay on the cabin with Jeff.
As she thought about Jeff, she felt her penis and vagina aching for action. She noticed that her body was craving for sex. She felt like she was starving and promptly knew what she needed: she was craving sperm!
Mary knew she needed sperm to fuel her succubus powers. But she didn’t want Jeff to find out her changes as soon as he entered the cabin. All she could think was going out and taking the sperm from other men, but she didn’t want to betray her husband.
