She wanted to know how to use a butt plug

My hot blonde girlfriend is very dumb when it comes to sex. She doesn't know anything and today she asked me how to use a butt plug. So, I told her to take off her clothes and shove this butt plug in her asshole. Once she does that and her asshole is wide enough, I shoved my big cock in her ass. I fucked her ass until I was ready to cum and she had a lot of orgasms.
