Ok Fine We Can Fuck, but Only My Butthole!

My stepson was horny and loafing around the house and asking me for sex. I told him sternly we could not have sex. He just wouldn't shut up though so I finally told him he could use my butt for his penis if he needed to fuck something till he came.... and I am still farting his cum out of my ass hole the next day!
