We want more!

The Merman King and the other mermaid royal guards were swimming back and forth inside of the pool.

The Merman Queen called Ariel over to rub her tail along with her.

The two of them had astonished looks on their faces as they rubbed her tail.

It seemed that these customers were quite satisfied with the products that I showed them.

It seemed that there wouldn't be any problems in having them as repeat customers in the future.

But it turned out that I had underestimated how much they liked the product.

The Merman King and his mermaid royal guards kept swimming in the pool for a bit before they were satisfied. Or rather, it was better to say that they had no choice but to stop because the Merman Queen was finished admiring the lube's moisturizing effect on her tail.

She had glared at the Merman King and the others, forcing them to come out of the pool.

Since they had been swimming for a bit, it was already time for lunch.
