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 to my step-son.  I arrive home late at night. The boys are in the living room playing video games as I sit on the couch legs crossed ladylike style in tight blue jeans.    I start farting during the conversation as each fart keeps getting longer, and more drawn out.  I don’t even apologize while farting.   I am clearly showing off today with my super long slow released bubbly farts on the couch.  Each fart I rip I can see how his friend turns his head in amazement.  I know how much I am turning both of them on but I play it off like nothing. Eventually my step-son leaves to jerk off in the bathroom leaving me alone in the living room with his friend.   Now’s my chance to really impress him.  I am sitting legs crossed farting my brains out while talking to the friend, impressing him with my abilities to fart super long drawn out musical multitoned bubbly farts.   I want to push him to the point of having to leave the room to jerk off as well but there’s only one bathroom in the house.  He’s needs to stay with me in the living room, so I just keep teasing him with my farts.  His dick is so hard at this point, yet I want to prove to him that my farts are the best.     The friend eventually says goodnight and excuses himself to bed and leaves towards my step-sons room.   What you don’t realize though is the friend secretly hides under the couch that you’re sitting on.  He eventually cums and waits for me to leave, but I still have a lot of gas and stay there to fart some more.  I just sit there gulping my brains out and he cums AGAIN because my farts are just too sexy sounding for him to handle.
