[Their kiss had been part of the mating ritual. Laura was about to tell Kotarou he’d be able to breathe underwater for the night, but was immediately distracted by his palms rubbing against her breasts.]

You can touch them all you want. I mean not when we’re in class or anything, but whenever we’re alone.

[No one else had ever touched her tits, and it felt nicer than she imagined. Especially when he brushed against her small pink nipples. A far away gleeful look settled on her face before she shook her head.]

No. This is important. Kotarou our kiss was part of mermaid magic. Just for tonight you’ll be able to breath underwater. It will make it easier.

And when we’re under I want you to use your mouth on my boobs. I think it will feel really good.
