Amethyst's Multifandom Mermay Fics

Picnics, Pegging, and Plots
A merman, a strap-on, and an empty beach.
When Lumine fulfills a private commission for Neuvillette and Furina, she was not expecting to find them with fish tails, and certainly wasn't expecting them to invite her to join.
My Favorite Catch -WanLumi / ScaraLumi - Merman! Scara
Lumine is determined to find why The Wanderer avoids water so much and invites him fishing. To her surprise, she finds the greatest catch of them all.
Hope you enjoy with more to come because I adore merfolk! Leave a comment if you liked!
