Drew and Kendra say by the pool long enough that their tails dried out and slowly reverted back to legs. Drew had some difficulty standing up; having never had a tail before, going back to legs was an odd experience that left him a little unsteady on his feet. Kendra recalled a similar experience after her first transformation. She stood up and reached out her hands to help Drew. This gave Drew his first real look at Kendra in her naked female human glory. Even after seeing her as a mermaid, it was a sight to behold. Kendra wasn't going to win any modeling contests and didn't flaunt her looks with skimpy outfits, but she was still an attractive girl who would turn more than a few heads. Drew got lost in the moment as his eyes wandered her body.
"Earth to Drew" said Kendra, snapping him back.
Drew took Kendra's outstretched hands and got back on his feet.
"Sorry to zone out there. You're beautiful."
Drew kissed Kendra, pulling her close. Kendra wasn't in any hurry to stop him.
"I see you body agrees" said Kendra when their lips finally parted and gently wrapped her hand around his erection. "No so tired after all?"
"I might be getting a second wind."
"Today was the first time I've had sex since I started turning into a mermaid. A part of me wants to try sex again in human form..."
"And the other part of you?" wondered Drew.
"I've never had sex with a merman before" said Kendra, licking her lips in anticipation. "How about the hot tub this time?"
Drew nodded and Kendra led him over, removed the hot tub's cover, and started the water jets. They climbed in, with Drew finding a comfortable seat and Kendra straddling him. They could both feel their respective transformations as they made out, grinding their bodies together. Drew's transformation into a merman happened first, his penis withdrawing into a slit in his blue fish tail. Purple scales covered Kendra's legs, but she held off her transformation into a mermaid by continuing to straddle Drew. Kendra wasn't sure how long she could stave it off when she felt Drew's penis sliding back out of its sheath. She positioned herself to take it, the head slowly slipping into her waiting slit. Drew put his hands on Kendra's ass, holding her tight as he slid into her.
With Drew's first thrust, Kendra couldn't hold back her transformation any longer. Her legs slipped back and merged into a tail. The two mers shifted down to the bottom of the hot tub for a round of underwater lovemaking.
