Miraculously, you made it out of the mermaid's room, out of the hallway, down the stairs, out of the mansion, down the path, out of the park, and back to your home without so much as a stumble. No one seemed to notice or care about your mermaid companion that you were carrying in your arms, either.
However, your arms were beginning to hurt by now from carrying her, despite her looking light.
"I do hope we get there soon. I am starting to feel a bit dry ...," she commented as she released one arm from around you to rub her slightly webbed hand against her scales.
Then it hit you like a flash. In your haste and your lust, you had forgotten that there would be nowhere she could swim at your home, given you didn't have a pool. The best you had was a bathtub and a shower stall.
You made your way into your house and towards the bathroom, the mermaid having to help you open the doors as you had your hands full.
"You're kidding, right?," she asked as her caudal fin flapped about in midair as she looked at the bathtub.
"No, sadly, I'm not ... I don't have a pool," you said a bit embarrassed at your blunder and not thinking things through.
"I assumed you at least had a pool when you asked me if you could take me to your home," she replied in a frustrated tone as her large tail fin flapped about again.
At that, similarly frustrated at her tone and because your arms felt like they were about to give out anyway, you dropped her to the tiled floor. This caused her to rub at her scaly backside at a moment or two with one of her webbed hands.
"I'm sorry, but right now you don't seem to have any choice," you said, initially frustrated with the mermaid. However, upon seeing her tail fin flap frustratingly or even angrily against the floor, you sighed, knelt down beside her and placed a hand on her shoulder as you tried to cheer her up.
"I'll look into getting you a pool or a tank... or something bigger, but for now, this will have to do."
"Fine...," she replied as a sigh that still sounded frustrated escaped from her. "Just help me get in ..."
You fulfilled the request and helped the mermaid into the bathtub. You assumed she would like warm water, and so you turn both knobs on the faucet to get the water at the right temperature. In response to the water rushing over her scales and skin, she released a sigh of relief as the water began to fill up the tub, eventually stopping a bit above her large breasts. The only problem seemed to be that her caudal fin stuck out of the tub as it was too small to fit all of her.
"I do hope you get to build that pool soon enough ...," she said with a small smile on her face and otherwise sounding content in her tone of voice but the words were or implied anything but (completely) content.
