Giving my sister a vibrator for her 18yo birthday unlocked her squirting skills

My sister is 18 years old, and for her birthday, I wanted to give her something fun. So, I bought her a vibrator.
When I gave her the vibrator, she was really surprised, but she said that she was excited to give it a try. I helped her set it up, and we started to play together.
After a couple of minutes, she started to squirt. She told me that she never has squirted before, and that it was really enjoyable.
We kept playing together, and we both squirted multiple times. It was a fun experience, and I'm glad that I did it.
