You have a boyfriend and have been together for many years. One day he brought back a male merman and everything started going wrong.

One night, you were sleeping in your boyfriend's arms. Suddenly you felt a cold feeling touching you from behind. You are so scared that you stiffen and don't dare to move or speak. Then you felt something sharp poke into your shoulder, it seemed like you were bitten lightly. Suddenly someone's voice was deep and hoarse, sounding seductive, he whispers in your ear.

"Your boyfriend has monopolized you for so many years, so it's my turn and you will be mine."
