Request: Brian to Lucia

"Mrs. Martinez...?" Evan asked hesitantly. His foxy neighbor had never come over to his house, and she certainly never dressed like she was now.

"Please call me Lucia... " the sexy older woman said before breaking out in laughter. "You really don't recognize me? It's me: Brian. I finally got my DNA resequencer to work. I used that sample we took from Mrs. Martinez's to turn myself into her exact duplicate. Think of the fun we're going to have with this."

"I can think of some fun I'd like to have right now," Evan said, the bulge in his pants leaving no mystery as to his meaning.

"Dream on, little man," the newly minted Lucia Martinez said. "With a body like this I have my sights set higher than the likes of you."

"You're laughing now," Evan said, "But I'll bet you fifty dollars you forgot to save a sample of your own DNA so you could change back."

Lucia's smile faded.

"Oh.  Shit."
