I visit my best friend's home for the night and surprise her boyfriend with oral pleasure, resulting in him ejaculating in my mouth as she is away at work

I decided to visit my best friend for the night, and as soon as I arrived, I couldn't resist the urge to surprise her boyfriend with some oral pleasure. Even though he's not exactly my favorite person, I figured it would be fun to do something naughty while her away. After making sure that her husband was asleep, I went ahead and started giving him a blowjob, hoping that my friend wouldn't find out. As I was sucking his cock, he suddenly shot his load right into my mouth, leaving me covered in cum. I quickly got up and ran to my friend's room, pretending nothing had happened.
