Mom finished me off

Long story short, my mom walked in to the computer room where I was masturbating and watching porn. She had just gotten home from work and Zumba. She came in to ask how my day went/ what I wanted for dinner but instead saw me jacking off and proceeded to see what I was watching. It was an anal milf gallery with just spread assholes. Again long story short she used her purple vibrator to make me cum by taking one of her sweaty socks off, put the vibrator in it and wrapped it around my balls. She held my arms behind my back while the vibrator took about 5 minutes to make me cum. There was a lot of communication however this would turn into a novel if I didn't leave out those details.
