Trigger Warning: Rape Naive mermaid boy wants to become human. He asks his lifelong friend the human magician who lives under the sea and has his wish granted only to be raped by the magicians sea creatures and then the magician himself. Let’s face it, this was a thinly created plot for an underwater tentacle porn bonanza of restraints and forced pleasure. It didn’t tick any erotic boxes for me because I felt no emotional connection between the guys.
Adults (i guess). This is pretty fucked up. I'll give it points for creativity, and the author going completely balls-out on this one. There are certainly problematic elements here, but it's more like gay tentacle porn.
It's so weird and annoying, like how convenient that you raped this guy you supposedly love and it's okay because he actually loved you, too! Like, it's NOT okay, and wtf. I hate how yaoi tries to make rape cute. Plus, wtf, I love how he apologizes to the sea creatures on his dick. This artist has some odd kinks.
As it says, its between a mermaid and a magician one-shot smut. Mermaid wants to be human and asked his childhood friend, a magician, to transform him. It was a success but the mermaid was ravaged by the magician. Smut, tentacle, fish, rape, romance at the end.
