I shave my pussy in front of my husband's brother and end up masturbating for him until I cum.

My beautician couldn't make an appointment for a wax, so I had to shave my pussy myself for the first time. Since I didn't know how to do it, my husband's brother said he could tell me how, so I did. But the friction from the razor got me wet, and I ended up masturbating for him and squirting cum. He masturbated while I enjoyed the show.
