A few minutes later, you hear a noise at your front door. A glance at the clock tells you it's probably your your girlfriend come home from work.
You meet her with a kiss just inside the door.
"How was your day?" you ask.
"I hate my stupid boring office job" she replies. She kicks off her shoes and puts down her purse. "But one thing always gets me through the day, especially today: thinking of you."
She presses her lips to yours then presses her whole body against yours. Her kiss makes it clear in what way she was thinking about you. Your sex life has always been good, but this is an unexpected surprise. The two of you make your way to the bedroom, bouncing off walls and doors in the process as you both kiss and grope and pull off articles of clothing. You're both naked by the time you tumble onto the bed.
"I wouldn't want to make love to anyone but you" your girlfriend declares. You're reminded of your wish with the genie. It was real after all!
During sex, you hand slides to your girlfriend's hip and you feel something a little strange, almost like a couple scales. Your girlfriend moans when your run your fingers over the area.
Afterwards, the two of you lay in bed together, exhausted by your lovemaking session. Your girlfriend falls asleep first and you take the opportunity to take a look at her hip area where you felt scales before. Sure enough, there are a few little spots that look like fish scales. Your wish is coming true: your girlfriend's month-long transformation into a mermaid has begun!
