Step-son gets caught sniffing panties

While I was in the kitchen cooking, my step-son thought it would be a smart idea to sneak into my bedroom and look through my panties drawer. Who would've thought that he would be really that naughty? I was most certainly not expecting that from him, but since he did it, I decided to interrogate him a little about this little fetish oh his. He told me he sniffed them but didn't manage to touch himself. He was obviously hard from it, though. When I asked him which smell turned him on the most about it, he avoided the answer, so I figured I'd find out all by myself whether it was the smell of my pussy or that of my ass that made him so incredibly weak haha. So I let some gas and made him smell it since I was feeling super gasy anyway...and I'm pretty sure I figured out which smell he likes the most. I'm sure after inhaling and tasting my farts he'll remember to be a good boy, so he doesn't get in trouble anymore, though!
