Farting in front of my stepbrother, it'll be our secret!

Description: It was the first time i farted in front of my stepbrother. it was a little awkward at first. but when i realized he didn't mind, i kept doing it. at first, he would look at me and sniff them with relish and pleasure. so then i suggested we keep this secret between us. i would let him sniff my farts, and he wouldn't tell anyone about my hidden fetish. that way, we'd both win.
