My girlfriend squirted for the first time in her life after roleplaying a fantasy she had been masturbating over for years but had never shared with anyone else

I’ve never written anything here but this is something I just have to share. Me and my girlfriend ended up having sex last night after a hard day at work, we were both tired but we decided to make the effort. I began with oral sex, and I ended up making her cum with a clitoral orgasm which is the only orgasm she can have… or so we thought.
