The three cuts under each of her breasts were peculiar to say the least. They didn't hurt at all, and there wasn't any blood from them. As she breathed in and out, thin flaps of skin slightly overlapping the cuts flared out, and then closed. She gingerly touched her webbed hands along the openings in her sides, feeling the slightly rubbery flaps of skin. As she did so, the touches sent shivers to her loins.
Marina licked her lips, as she soon realized what it was that had sprouted under her tits. Gills! Marina had grown gills. That's why she was under the water for so long. She smirked, and marveled at the feeling of her gills flaring outward as she breathed in. She wanted water. Water to breathe through her new gill slits. Without thinking, her webbed hands soon started cupping her tits, rubbing them, and pinching her nipples, which had now taken on a more blue tint. "I feel, fishy..." she said aloud as she stood up and walked into the water.
