Author's Note: In the myth of Alpheus & Arethusa, Alpheus' love/lust is never realized. In this version I decided that it is, but in a way that it's very close to a non-consensual union. So just be forewarned... and Enjoy!
------------------------------
Arethusa was an exceptionally beautiful nymph, lithe and sweet with a voice the birds envied. A follower of the Gods, Artemis was her favorite and she was seriously considering joining the virgin's vocation, the strong female band of followers that joined the Goddess on the Hunt. But Arethusa hesitated because she was not a strong nymph, and she did not particularly care for the hunt, but she deeply wanted to be part of Artemis' elite group.
The Goddess had noted her attention, but respected Arethusa's reservations, waiting for the nymph to come to her own decision. Artemis' band was not an easy group to be in, the nymphs were expected to hunt, to run with the fleetest stags, swim like fish, and to guard themselves from all male contact. Arethusa was swift enough on foot and in the water, and she had never felt the touch of a man nor wanted it, but she also could not quite reconcile to the killing of animals. She did not condemn the Huntress or any hunters... but she was not sure that she herself could do it.
And so, there came a day when she wanted a bathe, and she chose the stream belonging to the River-God Alpheus (although she knew it not), and she did not have the Goddess' protection.

Alpheus felt his waters swirling around the most enchanting form his cool reach had ever touched, supple thighs and firm pert breasts, long trailing hair like vines in his waters. He groaned, letting his presence rush towards the beauty bathing herself in his swift waters, and he circled around her body.
