Lana nods eagerly. "So how does this happen?" she asked.
"It seems that whatever I fantasize about sexually becomes reality" explained Amy. "I fantasized about being a lesbian mermaid, hence Aurora. I think you can guess what I fantasized about this morning..." she said, gesturing to her erect penis.
"And now you're fantasizing about me?" said Lana.
"Oh yes. When someone puts their penis in me, it turns them into a mermaid. So I like the idea of when I put my penis into someone, they get a penis. Does that sound good to you?"
"When I saw you and Aurora in the shower, I wanted your penis in me almost as much as I wanted to have a penis like yours."
Lana quickly removed her shorts and spread her legs wide. Amy crawled over and onto Lana, finding her already wet with anticipation. The two kissed - tentatively at first then more passionately. They began fondling each other's chests, but Lana was quickly tired appetizers and wanted the main course. "Give me your dick! Please!"
Amy obliged, sliding into Lana. Lana was in heaven, having never had such a big penis in her before. She wrapped her legs around Amy and drove the mermaid into a fast rhythm.
