"Well," Ty said in the brunette's voice. "That was amazing, but I think it's time we went our separate ways."
Ty looked down at her exposed breasts and decided it would be best to put them away and generally put her back where he found her. Otherwise, she would probably be very confused about how she ended up in an alleyway with her tits hanging out. He struggled a minute to put her bra back on properly. It was a puzzle that he had never faced before today, dealing with female undergarments.
Eventually, he gave up. He needed help, he realized. He needed the Internet. He probed her jeans and found her little phone crammed down a front pocket. The case was glittery, and the screen was cracked. Thankfully, she had not added any password to opening it. One swipe and he had access to all the accumulated knowledge of humanity. Hopefully someone out there could explain women's underwear to him.
At last, he discovered a site that described how he could put the bra on backwards and attach the hooks under her breasts. Then, he just needed to rotate the bra around 180 degrees and stuff her massive breasts into the cups. He followed the directions, and it worked like a charm.
"Thank you random Internet people," he said, once more enjoying her soft voice. He put her phone back in her pocket. Finally, he buttoned up her shirt and stood her up again.
Once he was confident that she was back to the way he had found her (aside from having some dampness in her panties from masturbating), Ty walked her out of the alley right back to where he had first possessed her. He even tried to stand her in the same pose and to face the same direction as she had been in before.
"Goodbye," he said to hear her very pleasant voice one last time. Then, he concentrated on leaving her body behind and reappearing where he had been before as well. He blinked a moment and found himself standing exactly where he had planned to be, back in his original male body again. He watched as the brunette took control over her body again. She shook her head for a moment as if to clear her thoughts. Then, she just shrugged her shoulders and walked off down the street, apparently unaware that anything strange had happened to her.
Ty watched her for a few seconds and then walked away in the other direction. He wondered what he might do next.
