"I wonder who Sarah Smith is," you muse out loud looking at the tag. You sighed as you realized that you would have to drive back to the airport to take the bag back. But you were tired and you figured that it could wait until tomorrow morning. After all airlines have lost bags longer than a day before so it wouldn't be that unusual for one to be gone for a few hours. In fact this probably explains why bags are lost in the first place, people mistakenly pick them up and don't return them right away. Well it was time to get ready for bed.
After brushing your teeth and using the bathroom you take off your clothes and you were about to put on the t-shirt and silk boxers you wear to bed when you remembered that they're still in your suitcase that you don't have. "Shit," you mutter remembering this and also remembering that your boxers were also in that suitcase. Well you supposed you could always sleep naked but you really didn't want to ever since the one night where a spider had bitten you on your nipples and dick. Still you don't have anything to wear to bed so you'll just have to risk it.
You had taken off your clothes when you automatically opened up the suitcase and pulled out a pair of silk panties and a silk nightgown. When you looked at them you were sure that they wouldn't fit as they seemed to be for either a petite woman or a preteen girl. You knew you shouldn't try to wear them but for some reason you put the panties on sliding them up your legs. They were difficult to get on but somehow you were able to pull them up. Your dick and balls were kind of squished especially seeing as how you were getting hard from the feel of the panties. However instead of taking them back off you picked up the nightgown and struggled into it. It was a bit looser than the panties but still it was tight especially on the short sleeves. You had to wonder how you didn't rip a seem in either one or the material. How that happened you have no idea. You knew you should take them off but for some reason you just went to bed and fell into a deep sleep.
As you slept your body changed. Your height decreased from five foot eight to four foot nine. Your weight went from 180 pounds to 83 pounds. Your hair grew out from it's short length to waist length and changed from brown to light ash brown. Your eyes changed from blue green to brown. Your face rearranged changing from a square face to an oval face. Your areola around your nipples enlarge a bit and a small mound forms under your nipples giving you small breasts. Your balls pulled up into your body as the body of your dick split on the underside. Your dick shrank as it repositioned itself between your legs forming your new clit. Your ballsack formed the outer lips while what had been your dick's body formed the inner lips. Your prostate enlarged until it was your new womb and it connected to the outside forming your vagina. The last change was your ears became pierced.
Once the changes were finished you and the suitcase faded out and would reappear somewhere else. This would lead to a baffling case of your disappearance over the next few days but that isn't really a concern for you now. What is a concern for you now is where you'll be waking up at.
