Imagine a blender inside a bowl of pea soup that's on fire.

A kind of churning began immediately every spot that the pill touched as it dissolved. "Oh god, what the fuck..." He became nauseous and it felt like his stomach was literally spinning inside of his body. He could feel himself expanding, like he was an inflating water balloon. "Hurgghhh! What...?!" Pressure was on his chest as the water poured the most into that area and his hips and legs.

This was coupled with a curious sensation of his bones and muscles shrinking and becoming noticeably more fragile. He had been so occupied these bizarre sensations that he slouched in the chair with his legs splayed wide and his head thrown back. The female scientist gripped his hand tried to reassure him. "You're doing great honey, just a little longer."

He gripped her hand tightly and felting an inward sucking pressure in his crotch. He felt his cock and balls tunnel into his body a kind of hot dissolving occur inside of him. "OH GOD WHAT THE FUCK!" , he screamed, and just like that it was over. "It's ok honey, look here.", she brought over a portable full length mirror on rollers and gawked at a stranger in the mirror.

"Holy crap... That's me?", he said as he touched his remolded face. "Wow... I'm beautiful."

"Yep honey, that's you, for the next 11 eleven months. Even 12 if you want."

He looked down at his crotch and stared at it. Then he touched to confirm it was real. "Holy crap. I'm a woman..." A few of the male scientists chuckled and one handed him a patient gown. As he put it on, the female scientist continued, "There are some caveats here, Henry. You can get pregnant while in this form, though it's a low percentage probability. If that happens, there will be a hormonal shift in your body and it will become permanent, so I recommend you use protection if you ever want to be a man again. Additionally, you will be sharing room and board with other X-Change volunteers under observation. You will notice emotional and cognitive changes that may upset you and we are all here for your support. You will go through a battery of tests every week day and you will get week ends off to do what you like with your new body. You've signed a very strong non-disclosure agreement. If you tell anyone about this before the trial is over, you won't get anything. I just wanted you to know that. I'm sure you want to get paid."

"What's your name by the way?", Henry asked the female scientist as she opened the door to his --- her room she would be staying in for the next year. "Jamie. It's a pleasure to make your acquaintance. We have everything you would want here. Television, internet access, stocked refrigerator, shower, closet. Fully furnished. You'll get a 1000 dollar weekly sum to do with what you like. I recommend you don't spend it all in one place, it comes out of your contract fee. Tomorrow morning will be the weekly meeting with all the other girls at 9 AM. We like to get started early. By the way, you're going to need to pick a new name for the duration. We can't rightly go around calling you 'Henry" now, can we?"

Henry pondered for a moment and it came pretty quickly. "Hannah, Hannah sounds good."

Jamie smiled, "Hannah is a beautiful name. Well Hannah, until tomorrow, sleep well." Jamie left and shut the door behind her and Henry-now-Hannah excitedly dashed over to the bathroom mirror. She bounced up and down watching her breasts bounce with her. She squealed an "oh my gooood!" squeal she'd rolled her eyes at when hearing it from girls when she was young. She began pouring a hot bath in excitement.
