haha man, thats going a little too far to hide it. I would have just come clean after she said she knew what you were doing, since in fact SHE KNEW WHAT YOU WERE DOING. Hiding it in your ass only means she didnt find it, but doesnt escape the fact that she knows. Thats how my mom is kinda, and when she caught me back in the day, I just came clean. No use hiding something I do every day. I guess I don't like being a sneak that much.

Funny story though. That might teach you something about being so careless and smoking in a parked car. Roll that shit up and drive sonn.
