As you swim there, treading water in that warm lagoon, naked with those totally sexy mermaids, they smile mysteriously but alluringly at you with come-hither looks. You are about to swim closer when you hear some splashing: it looks like the mermaids have beaten you to it.
Soon, three or four mermaids swim less than a foot away from you. One mermaid swims in front of you and you get a nice, good, long look at her voluptuous body. She has long, wet, slightly curly red hair, dazzling sea-green eyes, a rounded, youthful face, full red lips, and smooth, pale skin. As your eyes travel down her body you become intimately aware of her perfect figute: perfectly rounded, free breasts, a thin hourglass waist, at the bottom of which begins her glistening orange-brown fish tail.
Her hands touching your face bring you back to reality, and they pull your face back to hers. She smiles into your eyes, and as you smile back, your thoughts are lost again. It is not simply a case of nervousness, your mind begins to cloud as she gazes deeply into your eyes. Then she swims closer, sliding her perfect body against your naked form as she does so. Your member jumps at attention. She closes the distance, closing her eyes and kissing you fully and with her tongue.
It seems like forever, You kiss for what feels like hours, before she pulls away, smiling at you. The tingling feeling in your body grows more fervent, and your breathing is quick-paced and shallow. You are so caught up by the mermaid's beauty that you are unaware of the changes that are taking place...
