She does.

“Okay...” I answered the stranger sheepishly.

“Excellent. My name's Benjamin by the way, but please call me Ben.”

“I'm Heather.”

“Nice to meet you Heather. Now go get your cute butt in there and try them on!”

I stepped into the changing room and he followed me in. There were four cubicles in the room with curtains to shield yourself from prying eyes. The room and each cubicle were empty, so I stepped into the closest one and slid the curtain closed. I pulled off the haphazard clothes I threw on this morning and slipped on a pair of panties and a bra. I was surprisingly thankful to finally have some underwear on me. I was most curious about the jeans so I put those on and then one of the tops that revealed some of my belly.

I looked into the mirror and it still took me a moment to remember that the reflection was really me. No more pudgy flabs of fat for limbs, I was now a slender sexy blonde. The jeans were really hugging my legs, and as I spun around I nearly gasped at how great my butt looked! I then took a deep breath and open the curtain to show the outfit to the stranger, Ben.

“Ooh! You look fantastic!” Ben seemed ecstatic about the outfit I picked, or more likely my body.

“Thanks.” I answered, still shyly but I was starting to warm to him.

I went back into the cubicle and changed into the skirt and a top with revealing cleavage. My breasts used to be on the small side and I was too shy to try and wear a push-up bra. But the breasts on this new body were amazing, they were so perky I didn't even need a bra at all! I stepped out to show Ben and he howled at this outfit as well. I even did a little twirl for him which lifted the skirt high enough for him to catch a glimpse of my underwear. I don't quite know why but the more I had this body the more cavalier I felt.

“You really do look fantastic Heather.” Ben smiled as he watched me pose the outfit for him. “Say, didn't I see you holding some lingerie?”

“Yeah.”

“Well why don't you try that on?”

“I don't know. What if someone comes in here?”

“Oh don't worry about that! Or how about I just come into the stall when you're ready?”

I'm not exactly sure why I did, but I agreed to his proposal. After all he was willing to pay for all these clothes, it's the least I could do. So I stepped into the cubicle again and changed into the sexy lingerie. It was black lacey bra and panties with sheer black stockings and a garter belt. I never in my life thought I would be able to wear something like this, and I loved it!

“Okay, you can come in.” I called for Ben. I was nervous about all this, but it was slowly turning into calm.

I backed to the corner of the stall to make room for Ben as he pulled the curtain aside and stepped in. His eyes lit up as he looked up and down my body. He asked me to turn around, I saw his reflection in the mirror and his eyes were locked on my butt.

“Damn Heather. You have a great body. How old are you?”

“Eighteen.”

“Oooh! Yes that is the ass of an eighteen year old.”

I was starting to really like hearing him compliment me, perhaps too much. That's when I felt his hands on my waist and I instinctively jumped away from him, but I was already in the corner so I didn't have far to go.

“Come on Heather.” He pulled his hands away from me. “You can't expect me to see you in that outfit and not make a move. I know you want it.”

“I just...” I was suspecting that he might not be wrong about that, but I still wasn't sure.

“I'm offering to pay for your clothes. If you just repay me now, we'll be even. Alright?”
