Mama vitregă se fute la miezul nopții 3

My step-son brings his friend over for a sleepover.I want to show his friend just how much better at farting I am compared to his step-mom because I heard him telling this.I arrive home late at night.The boys are in the living room playing games as I sit on the couch legs crossed in tight blue jeans.    I start farting during the conversation.I don’t even apologize while farting.I know how much I am turning both of them on.My step-son leaves to jerk off in the bathroom leaving me with his friend.   Now’s my chance to impress him.I am sitting legs crossed farting impressing with my abilities to fart long musical bubbly farts.I want to push him to the point of having to leave the room to jerk off but there’s only one bathroom.He needs to stay with me so I just keep teasing him. He eventually says goodnight and excuses himself.What I don’t realize is he hides under the couch.He eventually cums and waits for me to leave,but I still have a lot of gas.He cums AGAIN.
