Every member of the church would like to believe that they never have sinful thoughts. As one can imagine though, this simply isn't true. Even the most devout members of the church slip up occasionally. Luckily for them, there are seldom consequences for these transgressions of thought. David, however, did not have this luxury. 

It had been a pretty typical Sunday for David until he took a new way home from church. On his walk, he stumbled upon a small church he had never seen before. Curious has to what the inside looked like, he decided to saunter up to the front door for a peek. The stone steps leading up to the old wooden doors looked regal, and he climbed them carefully, admiring the ornate details of the stonework. The front doors of the church were large and imposing. David reached out a hand to one of the large iron hoops that hung from the wooden doors and pulled.

The door swung open, but not without great effort on David’s behalf. It seemed dark inside, and it took David’s eyes some time to adjust to the difference in light. Once they did though, he saw that he was looking upon one of the most beautiful church interiors he had ever seen. Every inch of the place seemed to be covered in intricate detail and extreme craftsmanship. David made his way into the church, examining it as he did. It was absolutely breathtaking.

There did not seem to be anyone around, and it was dead silent inside the church. David walked down the center aisle between the pews to the altar. The altar was the centerpiece of the room and was the only thing properly lit by a skylight above. It was intricately detailed and embellished with bits of gold and sparkling gems. David made his way around to gaze down at where there might have been a bible lying open on the altar. There, however, was no bible at all. Instead, there was an inscription carved neatly into the marble. It read:

Those who claim perfection touch the pedestal
Be tried by angels who read thoughts within your skull
If you are pure of heart, you will remain unscathed
But if you are to waiver, your body shall become depraved

David thought this seemed ominous, but surely it was just an inscription. David reached out and placed a hand upon the engraved words. Then, as if it could sense his touch, the pedestal began to glow with a soft, warm light. The jewels sparkled, and the gold seemed to hum with power. As this happened, he heard a voice speak within his head, “The challenge has begun. Now keep your mind free of sin.” Scared and a bit shaken by what had just happened, David ran out of the church. He gave it one last glance as he started to make his way back home, determined never to set foot inside again.

David walked fast, hoping to just go home and get back in bed. A woman walked towards him, heading in the opposite direction. For a moment, he thought about what she might look like naked. Instantly, he felt an odd sensation on his skin. He looked at his forearm and found that a tattoo had appeared. David had never gotten a tattoo before, and this one depicted a sexual act between two people. The words on the pedestal had been true! How long would he have to keep his mind free of sinful thoughts?

As soon as David got home, he went right to bed, hoping it was all a bad dream. As he dreamed, his mind conjured images of nude women doing all manner of things to him and each other. He awoke with a start as soon as he realized what was happening. David looked down to find that he was now covered in more tattoos than before. Even his sleeping mind was subject to the rules of the trial. This was going to be challenging.

David spent much of the week trying to avoid people altogether and keeping his mind free of any sinful thinking. This was incredibly difficult though, as his own body now depicted several sex acts in bold black ink. Twice, he had slipped up and thought about having sex the first time, he had gained even more ink. The second time, a different change altogether started to develop. David’s cock had gotten noticeably smaller but also much more sensitive. Even brushing it against his pants brought him to the verge of cumming.

Finally, David had run out of groceries though. He would need to head out into public and get more. David put on his loosest-fitting pants and cinched them with a belt around his waist. Then he made his way out into the world. While he was on the bus, he saw one of the prettiest girls he had ever seen, instantly sending his mind somewhere it wasn’t supposed to go. He felt another shift in his crotch but wasn’t quite sure what had happened.

When he got to the grocery store, he went straight to the bathroom. He was about to go into a stall when he caught a glimpse of himself in the mirror and did a double-take. David no longer looked entirely like David. His face had lost many of its masculine features and looked more like a woman’s face. This was worrying. David entered the stall and pulled down his pants only to find that “He” was no longer an accurate pronoun. David’s penis was completely gone. She touched where it should have been, only to have an intense orgasmic feeling surge through her body as she brushed against the clit of her newly formed vagina.

This feeling was enough to count as a sinful thought, apparently because David felt more changes take hold. Two small mounds pushed out against David’s shirt, and without checking, she knew they were boobs. Mildly panicked but having a task to complete nonetheless, she pulled up her pants and walked back out of the bathroom. She got some weird looks from other shoppers as she emerged from the men's restroom while clearly looking like a woman.

David managed to get her groceries and check out without further incident. On the way home, it took everything in her not to think about anything that might be considered sinful. When she got back, she brought in her groceries and went straight to the bathroom, pulling off all of her clothes. She stared at herself in the mirror. A heavily tattooed woman with perky tits stared back. For a second, only a second, she thought about what it might be like to get fucked in this body. Instantly, her breasts swelled larger, fuller, and some new tattoos appeared near her crotch displaying the text “free use” and “cum goes here.”
Horrified but determined not to have any further changes occur to her body, she wrapped herself in a towel and sat in the living room. She began to meditate and told herself she would do just that until this challenge ended. And so she did. For two days, she meditated in her home until a familiar voice rang out in her head. “The challenge is complete. You look as you deserve.” With a sigh of relief, David collapsed on the floor, proud that she had been able to hold herself together for the remainder of the challenge. Unfortunately, she was now stuck looking the way that she did.

In the coming month, David would change her name to Jessica as it suited her current appearance better. She got a job working as a nun to atone for her past transgressions. Perhaps with enough hard work and determination, the angels would see fit to return her to her original self. It would be no easy task though. She was always getting hungry looks during church service, now in her new body, and it took everything in her not to let those looks win her over.
