Dan turned around as soon as Rachel said his name. Upon catching sight of her, the towel around his waist hit the ground. Rachel was always attractive and Dan always noticed it, but as a Mermaid, she was now in a league of her own.
Rachel meanwhile pulled her self out of the pool, her tail arching up over her head as she laid their seductively. Dan walked towards her. "Someone seems happy to be here." She said flirtatiously, noticing his fully erect member. Even her voice was sexier. Dan stammered as she slid back into the pool. "Come on in, the water is perfect." Rachel said, floating around in the pool, flirtatiously gesturing for him to join her. Dan complied as they swam up to each other.
They held each other close and started to make out, then, they passed first base, and Rachel clasped Dan's sensitive member in her hand, guiding it to her waiting slit. The two of them moaned as Dan's member found it's mark and they both started thrusting back and forth, slowly, slowly getting faster as they moaned passionately in sheer bliss.
